Factors  Influencing  the  Distribution  of  Overwintered  Bullfrog 
Tadpoles  (Rana  catesbeiana)  in  Two  Small  Ponds 

Abstract. 

We  studied  the  effects  of  vegetation,  temperature,  dissolved  oxygen,  and  depth  on  the 
distribution  of  overwintered  bullfrog  tadpoles,  Rana  catesbeiana ,  during  the  early  spring  within 
two  small  ponds  (Spring  Peeper  Pond  and  Okie  Minnow  Pond)  in  central  Ohio.  Vegetation  and 
water  temperature  significantly  influenced  tadpole  distribution  in  Olde  Minnow  Pond,  whereas 
oxygen  significantly  influenced  tadpole  distribution  in  Spring  Peeper  Pond.  Water  depth  did  not 
affect  tadpole  distribution  in  either  pond. 

In  more  northern  populations,  American  bullfrog  tadpoles  (Rana  catesbeiana )  typically 
overwinter.  Some  observations  suggest  that  bullfrog  tadpoles  shift  their  habitat  use  as  they  grow 
from  the  shallows  along  a  pond’s  edge  when  small  to  the  deeper  waters  at  the  center  of  a  pond  when 
larger  (e.g.,  Werner,  1992;  Smith  and  Rettig,  1996).  We  investigated  the  distribution  of  overwintered 
American  bullfrog  tadpoles  within  two  small  ponds  in  central  Ohio,  USA  during  the  early  Spring. 
We  were  particularly  interested  in  determining  if  various  physical  and  biotic  characteristics  could 
explain  variation  in  tadpole  distributions  within  and  between  these  ponds.  Within-pond  distributions 
of  anuran  larvae  can  be  a  function  of  water  depth,  presence  of  aquatic  vegetation,  substrate  type, 
dissolved  oxygen  content,  and  temperature  (e.g.,  Noland  and  Ultsch,  1981;  Alford,  1986;  Warkentin, 
1992;  Nie  et  aL,  1999;  Ultsch  et  al.,  1999;  Smith  et  ah,  2003). 


The  two  ponds  we  investigated.  Spring  Peeper  Pond  and  Olde  Minnow  Pond,  are  located 
on  the  Denison  University  Biological  Reserve,  Granville,  Licking  Co.,  Ohio,  USA  (40°05’00N, 
82°31’05”W;  elevation  =  308  m  asl).  The  ponds  are  separated  by  100  m.  In  a  typical  year,  Spring 
Peeper  dries  up  in  late  August  or  early  September  after  a  summer  drought  which  typically  lasts 
from  June  through  August;  however  for  2  or  3  years  prior  to  this  study,  Spring  Peeper  had  not  dried 
up  and  held  water  year  round.  Olde  Minnow  is  a  permanent  pond.  Both  ponds  are  supplied  by 
springs  and  run-off,  and  are  known  to  support  several  amphibian  species  (Schultz  and  Mick,  1998; 
Smith  et  ah,  2003). 

We  collected  information  on  abiotic  variables  and  bullfrog  tadpole  distributions  once  a 
week  from  25  March  to  1 1  April  2006.  Each  week  we  sampled  up  to  13  sites  around  the  perimeter 
of  each  pond.  We  assumed  that  because  of  temporal  changes  in  the  pond  and  time  between  samples 
that  the  samples  from  different  dates  were  independent  (see  Smith  et  al,  2003).  We  thus  pooled 
data  within  each  pond  for  our  analyses. 

In  order  to  estimate  the  abundance  of  tadpoles  at  each  site,  We  used  dipnets  to  complete 
3  1m  long  sweeps  at  each  site,  with  ample  time  between  sweeps  to  allow  for  tadpoles  to  return  to 
the  site.  The  number  of  tadpoles  was  recorded  after  each  series  of  sweeps.  Vegetative  cover  for  each 
site  was  visually  estimated  using  a  pre-determmed  scale  from  Ito  5,  with  1  denoting  no  vegetation, 
and  5  denoting  dense  vegetation.  Dissolved  oxygen  and  water  temperature  were  measured  at  each 
site  using  a  YSI  550 A  meter.  Each  of  these  measurements  was  taken  halfway  between  the  surface 
of  the  water  and  the  bottom  of  the  pond.  Depth  was  measured  using  a  meter  stick.  Regression 
analyses  were  used  to  examine  the  relationship  between  the  number  of  tadpoles  and  vegetative

Results. 

The  number  of  bullfrog  tadpoles  was  positively  correlated  with  vegetative  cover  in  Olde 
Minnow  Pond  (Bullfrog  tadpoles  =  0.037  +  0.889(vegetation  index);  n  =  27,  r2  =  0. 1 83,  P  =  0.0026) 
but  not  in  Spring  Peeper  Pond  ( n  =  28,  r 2  -  0.038,  P  =  0.32).  Tadpole  abundance  was  positively 
related  to  water  temperature  in  Olde  Minnow  Pond  (Bullfrog  tadpoles  =  -5.46  +  4.04(temperature); 
n-  27,  r2  =  0.171,  P  =  0.032),  but  not  in  Spring  Peeper  Pond  (n  =  28,  r2  =  0.091,  P  =  0.12).  There 
was  no  significant  relationship  between  dissolved  oxygen  and  tadpole  abundance  in  Olde  Minnow 
Pond  (n  =  23,  r2  =  0.012,  P  =  0.68),  but  a  significant  positive  relationship  was  found  in  Spring 
Peeper  Pond  (Bullfrog  tadpoles  =  -20.6  +  5.99(DO);  w  =  23,  r2  =  0.171,  P  =  0.0053).  Depth  did  not 
affect  tadpole  number  in  either  Spring  Peeper  Pond  (n  =  28,  r2  =  0.092,  P  =  0.12)  or  Olde  Minnow 
Pond  (n  =  27,  r2  =  0.048,  P  =  0.27). 


Discussion. 

Within  each  individual  pond,  different  factors  significantly  affected  tadpole  distribution. 
Vegetation  and  water  temperature  significantly  influenced  tadpole  distribution  in  Olde  Minnow  Pond, 
whereas  dissolved  oxygen  had  a  significant  influence  on  tadpole  distribution  in  Spring  Peeper  Pond. 
Water  depth  did  not  affect  tadpole  distribution  in  either  pond.  Our  results  are  partially  consistent 
with  previous  laboratory  experiments  and  field  observations  on  the  habitat  use  of  bullfrog  tadpoles. 
Overwintered  bullfrog  tadpoles  from  Ohio  have  been  shown  to  prefer  vegetation  to  bare  areas  in 
laboratory  studies  (Smith  and  Doupnik,  2005);  however,  overwintered  tadpoles  from  Michigan 
did  not  (Smith,  1999).  Oxygen  concentration  has  been  shown  to  be  important  in  habitat  selection 
of  bullfrog  tadpoles  (e.g.,  Nie  et  al.,  1999;  Ultsch  et  ah,  1999),  as  has  temperature  (Hutchison  and 
Hill,  1978;  Crawshaw  et  ah,  1992;  Ultsch  et  ah,  1999).

Note  on  Reproduction  of  two  species  of  microteiid 
lizards,  Leposoma  southi  and  Ptychoglossus  plicatus 
(Squamata:  Gymnophthalmidae) 

Leposoma  southi  and  Ptychoglossus  plicatus  are  common  diurnal  microteiid  lizard  in¬ 
habitants  of  leaf-litter  in  lowland  rain  forests  and  are  found  from  eastern  and  southwestern  Costa 
Rica  to  western  Colombia  (Scott,  1976;  Savage,  2002).  Information  on  reproduction  of  L.  southi  is 
in  Savage  (2002).  I  know  of  no  published  information  on  reproduction  of  P.  plicatus.  The  purpose 
of  this  note  is  to  present  information  on  the  reproductive  cycle  of  both  species  from  a  histological 
examination  of  museum  specimens  from  Costa  Rica  and  Colombia. 

Thirty-two  Leposoma  southi  (13  males,  mean  snout-vent  length,  SVL  =  33.4  mm  ±  0.87 
SD,  range  =  32-35  mm;  14  females,  SVL  =  35.0  mm  ±  1.9  SD,  range  =  33-38  mm;  5  neonates, 
SVL  =  15.4  mm  ±  0.55,  range  =15-16  mm)  from  Colombia  and  Costa  Rica  and  15  Ptychoglossus 
plicatus  (9  males,  SVL  =  52.0  mm,  ±  7.3  SD,  range  =  43-63  mm;  5  females,  SVL  =  53.4  mm  ± 
4.4  SD,  range  -  50-61  mm;  1  sub-adult  male,  SVL  =  39  mm  ±  0.00)  from  Costa  Rica  were  exam¬ 
ined  from  the  herpetology  collection  of  the  Natural  History  Museum  of  Los  Angeles  County,  Los 
Angeles,  California.  Male  and  female  mean  body  sizes  (SVL)  were  compared  with  an  unpaired  t 
test  using  Instat  (vers.  3.0b,  Graphpad  Software,  San  Diego,  CA).  Male  and  female  samples  of  L. 
southi  from  Colombia  and  Costa  Rica  were  combined  as  their  mean  SVLs  were  not  significantly 
different  (unpaired  r-test). 

The  following  specimens  of  L.  southi  were  examined:  Colombia,  Choco  District,  LACM 
45010,  45012-45015,  72817,  72819,  72820,  72824,  72826-72828,  72830,  72831,  72833,  72834, 
72838,  Costa  Rica,  Puntarenas  Province,  LACM1 59625- 159628, 159630, 159634, 159635, 159638- 
159641,  159644,  159645,159648,  159650.  Leposoma  southi  were  collected  1963  to  1973. 

The  following  specimens  of  P.  plicatus  were  examined:  Costa  Rica,  Heredia  Province, 
LACM  159263.  Limon  Province,  LACM  159278.  Puntarenas  Province,  LACM  114219,  159257, 
159262,  159264,  159266,  159267,  159275,  159277.  San  Jose  Province,  LACM  159260,  159261, 
159267,  159269,  159272,  159276.  Ptychoglossus  plicatus  were  collected  1969  to  1985. 

Gonads  were  dehydrated  in  ethanol,  embedded  in  paraffin,  sectioned  at  5  pm  and  stained 
with  Harris  hematoxylin  followed  by  eosin  counterstain  (Presnell  and  Schreibman,  1997).  Enlarged 
follicles  (>  3  mm)  and/or  oviductal  eggs  were  counted;  no  histology  was  done  on  them. 

All  L.  southi  males  were  undergoing  spermiogenesis  (sperm  formation).  The  seminiferous 
tubules  were  lined  by  spermatozoa  or  groups  of  metamorphosing  spermatids;  epididymides  contained 
sperm.  Samples  examined  by  month  were:  March  (n  =  2),  May  (n  =  2),  June  (n  =  5),  July  (n  =  3), 
August  (ri  =  1).  The  presence  of  males  producing  sperm  during  five  months  of  the  year  suggest  a 
prolonged  period  of  spermiogenesis.  The  smallest  reproductively  male  measured  32  mm  (LACM 
72828)  and  was  collected  in  June  from  Colombia. 

Leposoma  southi  females  were  significantly  larger  (SVL)  than  males  (unpaired  t  test,  t  = 
2.83,  df-  25,  P  -  0.01).  Females  exhibited  reproductive  activity  in  all  months  sampled  (Table  1). 
There  was  no  suggestion  (corpora  lutea  from  a  previous  clutch  and  yolk  deposition  for  a  subsequent 
clutch)  in  the  same  female  or  (oviducal  eggs  and  concomitant  yolk  deposition)  for  a  subsequent 
clutch.  However,  failure  to  find  such  females  may  be  due  to  my  small  sample  sizes.  Mean  clutch 
size  for  1 1  L.  southi  females  (enlarged  ovarian  follicles  >  3  mm  or  oviductal  eggs)  was  2.0  ±  0.0  SD. 
There  are  other  reports  of  clutches  of  two  eggs  for  L.  southi.  These  are  Taylor  (1956)  from  Costa

Rica  and  Fitch  (1970)  from  Panama  and  Costa  Rica.  Beebe  (1945)  reported  clutches  of  two  eggs 
for  the  congener  Leposoma  percarinatum  from  Guyana  as  did  Duellman  (1978)  for  L.  parietale 
from  Ecuador.  The  smallest  reproductively  active  females  measured  33  mm  and  were  undergoing 
early  yolk  deposition  (LACM  159630)  or  contained  oviductal  eggs  (LACM  72820,  72824,  72830, 
159645).  The  presence  of  reproductively  active  L.  southi  females  during  a  four  month  period  (Table 
1)  suggests  an  extended  reproductive  cycle.  Savage  (2002)  reported  reproduction  of  L .  southi  oc¬ 
curred  through  most  of  the  rainy  season  (May  to  November).  Telford  (1971)  noted  yolked  follicles 
in  his  available  monthly  samples  of  L.  southi  (November  to  July)  from  Colon  Province,  Panama.  I 
noted  presumed  neonates  of  L.  southi  in  the  LACM  collection  (15-16  mm  SVL)  from  May  (n  =  1), 
June  ( n  =  2),  July  (n  =  1),  August  (n  =  1)  also  suggesting  an  extended  period  of  reproduction. 

Considering  P.  plicatus,  there  was  no  significant  size  difference  (SVL)  between  males 
and  females  (unpaired  /-test,  P  =  0.70).  The  following  P.  plicatus  males  were  undergoing  spermio- 
genesis:  March  (n  =  1),  May  (n  =5),  August  (n  =  3);  epididymides  contained  sperm.  The  smallest 
reproductively  active  males  (undergoing  spermiogenesis)  measured  43  mm  SVL  (LACM  159264, 
159278)  and  were  collected  in  May.  One  male  (LACM  114219)  from  May  (39  mm  SVL)  contained 
spermatids,  but  no  spermatozoa  and  was  classified  as  a  sub-adult. 

Mean  clutch  size  for  five  P.  plicatus  females  (enlarged  ovarian  follicles  >  3  mm  or  ovi¬ 
ductal  eggs)  was  2.0  ±  0.0  SD.  All  five  females  examined  were  reproductively  active  with  enlarged 
follicles  (>  3  mm)  or  oviductal  eggs:  May  {n  =  1),  June  {n-  1),  August  (n  =  2),  September  (n  = 
1).  One  of  the  August  females  (LACM  159272)  contained  oviductal  eggs  and  concomitant  yolk 
deposition  for  a  subsequent  egg  clutch  suggesting  P.  plicatus  females  may  produce  multiple  egg 
clutches  in  the  same  year.  The  smallest  reproductively  active  female  (follicles  >  3  mm)  measured 
50  mm  SVL  (LACM  159276)  and  was  from  May. 

Harris  (1994)  reported  clutch  sizes  of  two  eggs  for  the  congeners  Ptychoglossus  bicolor 
and  P.  stenolepis  from  Colombia.  Dixon  and  Soini  (1975)  reported  clutches  of  two  eggs  for  Pty¬ 
choglossus  brevifrontalis  from  April,  June,  July,  September  and  December  in  Peru,  indicating  an 
extended  reproductive  season.  Duellman  (1978)  reported  two  oviductal  eggs  for  P.  brevifrontalis 
females  from  Ecuador.  These  observations  suggest  clutches  of  two  eggs  may  be  typical  for  Pty¬ 
choglossus. 

Considering  other  studies,  Telford  (1971)  reported  differences  in  timing  of  the  reproductive 
cycles  of  two  species  of  gymnophthalmid  lizards  from  Panama.  Reproduction  in  Gymnopthalmus 
speciosus  occurred  from  late  October  through  March  whereas  reproduction  in  Leposoma  rugiceps 
extended  from  May  through  November  (Telford,  1971).  In  a  detailed  study  of  reproduction  in 
the  gymnophthalmid  Potamites  ecpleopus  from  Peru,  (Sherbrooke,  1975)  reproduction  occurred 
throughout  the  year,  with  some  reduction  during  the  dry  season.

In  conclusion,  L.  southi  and  P.  plicatus  exhibit  prolonged  periods  of  reproduction  and 
produce  clutches  of  two  eggs.  This  appears  to  be  in  accordance  with  the  observation  of  Fitch  (1982) 
who  reported  there  were  reproductive  “patterns”  characteristic  for  species,  genera  and  higher  taxo¬ 
nomic  categories  of  tropical  reptiles.  Examination  of  additional  samples  will  be  needed  to  fully 
characterize  the  reproductive  cycles  of  L.  southi  and  P.  plicatus.  Also,  the  examination  of  gonads 
of  other  species  of  gymnophthalmid  lizards  from  Central  and  South  America  are  needed  before  the 
variations  in  the  timing  of  their  reproductive  cycles  can  be  ascertained. 

I  thank  Christine  Thacker  (LACM)  for  permission  to  examine  specimens  and  Sean  Kark 
(Whittier  College)  for  assistance  with  histology.  Leposoma  southi  and  Ptychoglossus  plicatus  from 
Costa  Rica  are  part  of  the  Costa  Rica  Expeditions  (CRE)  collection  donated  to  LACM  by  Jay  M.

Note  on  Reproduction  of  the  Sonoran  Leaf-toed  Gecko, 
Phyllodactylus  homolepidurus  (Squamata:  Gekkonidae) 
from  Sonora,  Mexico 

The  Sonoran  Leaf-toed  Gecko,  Phyllodactylus  homolepidurus  is  known  from  western 
Sonora,  Mexico  and  also  occurs  on  Isla  San  Pedro  Nolasco  (ca  15  km  SW  of  Punta  San  Pedro, 

N  of  Guaymas,  Sonora,  Mexico)  (Grismer,  2002).  While  there  are  no  reports  on  its  reproductive 
biology,  hatchlings  have  been  seen  in  early  October  (Grismer,  2002).  The  purpose  of  this  note 
is  to  report  information  on  its  reproductive  biology  from  a  histological  examination  of  gonadal 

material  from  museum  specimens. 

Twenty  P.  homolepidurus  (7  males,  mean  snout-vent  length,  SVL  =  56.7  mm  ±  2.7  SD, 
range  =  53-61  mm;  1 3  females,  mean  SVL  =  58.1  mm  ±  7.0  SD,  range  =  40-68  mm)  were  examined 
from  the  herpetology  collection  of  the  Natural  History  Museum  of  Los  Angeles  County  (LACM), 
Los  Angeles,  California.  Phyllodactylus  homolepidurus  were  collected  1964  to  1975;  MEXICO, 
Sonora:  LACM  3255,  58025-58027,  25086,  59951-59954,  59957-59959,  59963,  59964,  93783- 
93785,  93788,  93792,  122509. 

Gonads  were  dehydrated  in  ethanol,  embedded  in  paraffin,  sectioned  at  5  pm  and  stained 
with  Harris  hematoxylin  followed  by  eosin  counterstain  (Presnell  and  Schreibman,  1997).  Enlarged 
follicles  (>  4  mm)  and  or  oviductal  eggs  were  counted;  no  histology  was  done  on  them.  Male  and 
female  mean  body  sizes  (SVL)  were  compared  with  an  unpaired  t  test  using  Instat  (vers.  3.0b, 
Graphpad  Software,  San  Diego,  CA). 

There  was  no  significant  size  difference  between  male  and  female  P.  homolepidurus 
mean  body  sizes  (SVL)  (unpaired  t  test,  t  =  0.489,  df=  18,  P  -  0.63).  Two  stages  were  present  in 
the  testicular  cycle:  (1)  regression,  germinal  epithelium  is  reduced  and  consists  of  1-2  layers  of 
interspersed  spermatogonia  and  primary  spermatocytes,  seminiferous  tubules  are  reduced  in  size; 
(2)  spermiogenesis,  seminiferous  tubules  are  lined  by  spermatozoa,  clusters  of  metamorphosing 
spermatids  are  present;  epididymides  contain  sperm.  Testes  were  examined  from  June  (n  =  5)  1 
regression,  4  spermiogenesis;  August  (n  =  1)  1  regression;  December  (n  =  1)  spermiogenesis. 

Monthly  stages  in  the  ovarian  cycle  are  in  Table  1.  Four  stages  were  found:  (1)  No  yolk 
deposition,  “inactive”  follicles  with  no  vitellogenic  (=  yolk)  granules  present;  (2)  Early  yolk  deposi¬ 
tion,  vitellogenic  granules  present;  (3)  Enlarged  follicle  (>  4  mm)  for  future  clutch  and  one  oviductal 
egg  (soon  to  be  deposited);  (4)  Oviductal  egg  (soon  to  be  deposited).  Reproductively  active  females 
were  noted  in  June  (late  spring).  The  observation  of  hatchling  P.  homolepidurus  in  October  (Gris¬ 
mer,  2002)  would  support  deposition  of  eggs  in  late  spring  or  early  summer.  The  presence  of  one 
June  female  (LACM  59954)  with  a  shelled  oviductal  egg  for  an  upcoming  clutch  and  an  enlarged 
follicle  (>  4  mm)  for  a  subsequent  dutch  indicates  the  likelihood  that  P.  homolepidurus  produces 
multiple  clutches  in  the  same  year. 

Other  species  of  Phyllodactylus  from  South  America  (P,  kofordi,  P.  reissii )  and  south¬ 
ern  Mexico  (P.  muralis,  P.  tuberculosus,  P.  lanei)  exhibited  prolonged  reproductive  cycles  with 
reproductive  activity  in  much  of  the  year  (Dixon  and  Huey,  1970;  Goldberg,  2007;  Dixon,  1964; 
Ramirez-Sandoval  et  ah,  2006).  In  contrast,  Phyllodactylus xanti  from  southern  California,  exhibited 
a  “temperate”  seasonal  reproductive  cycle  in  which  spermiogenesis  occurred  in  spring,  regression 
in  summer  and  recrudescence  (=  recovery  of  germinal  epithelium  for  the  next  period  of  sperm 
formation)  in  autumn  (Goldberg,  1997).  My  finding  of  P.  homolepidurus  males  undergoing  sperm

formation  in  late  spring  (June),  one  regressed  male  from  summer  (August)  and  one  December 
male  undergoing  spermiogenesis  from  December  as  well  as  inactive  females  from  July,  September 
and  December  suggests  timing  of  the  reproductive  cycle  may  be  similar  to  that  of  P.  xanti.  Other 
lizards  of  the  North  American  southwest  also  reproduce  in  spring-early  summer;  see  for  example, 
Sceloporus  occidentalis  (Goldberg,  1973, 1974)  and  Sceloporus  vandenburgianus  (Goldberg,  1975). 
Grismer  (2002)  reported  P.  homolepidurus  is  probably  not  active  the  entire  year  which  would  tend 
to  support  my  suggestion  that  it  has  a  seasonal  reproductive  cycle.  Examination  of  additional  P. 
homolepidurus  are  required  to  further  elucidate  its  reproductive  cycle. 

I  thank  Christine  Thacker  (LACM)  for  permission  to  examine  Phyllodactylus  homolepi¬ 
durus  and  Sean  Kark  (Whittier  College)  for  preparation  of  histology  slides.

The  Amphibians  and  Reptiles  of  Erie  County,  Pennsylvania 

Brian  S.  Gray  and  Mark  Lethaby 

Abstract. 

Forty  -  five  amphibian  and  reptile  species  are  documented  from  Erie  County.  Current  status, 
natural  history,  dates  of  observation,  and  geographic  distribution  of  these  species  are  discussed.  Salamander 
diversity  and  snake  diversity  were  highest  in  Millcreek  Township,  with  eleven  and  ten  species,  respectively. 
Frog  diversity  was  highest  in  Girard  and  Millcreek  Townships  and  Presque  Isle,  all  with  nine  species  each.  The 
Five-lined  Skink,  the  county’s  only  lizard,  is  restricted  to  Conneaut  and  Springfield  Townships.  Presque  Isle 
had  the  greatest  diversity  of  turtles,  with  ten  chelonian  species  documented  there.  Greatest  overall  diversity 
(amphibians  and  reptiles  combined)  was  Millcreek  Township,  with  thirty  six  species.  The  number  of  species 
recorded  for  a  township  should  not  be  interpreted  as  reflecting  the  actual  number  of  species  occurring  there, 
since  surveying  efforts  have  tended  to  be  concentrated  in  areas  with  publicly  accessible  land.  However,  suitable 
habitat  may  be  lacking  in  some  areas,  e.g.  Franklin  Township,  where  the  landscape  is  dominated  by  agriculture 
and  residential  development. 


Erie  County  is  located  in  northwestern  Pennsylvania,  with  its  northern  edge  bordered 
by  approximately  43  miles  of  Lake  Erie  shoreline.  The  county  has  a  fairly  rich  herpetofauna  due 
to  the  variety  of  habitats  contained  within  a  diverse  landscape.  The  northern  tier  of  the  county  is 
within  the  Central  Lowland  Province,  which  is  characterized  by  low  ridges  of  sand  and  gravel. 
Forest  vegetation  in  this  region  is  primarily  beech/maple.  The  Appalachian  Plateaus  Province  is  a 
highland  with  hilly  topography  and  deep  valleys  due  to  stream  erosion  (Barnes  and  Sevon,  1996). 
Forest  vegetation  in  the  Appalachian  Province  is  composed  primarily  of  northern  hardwoods  (birch, 
beech,  maple  and  hemlock).  The  two  major  drainage  basins  in  the  county  are  the  Lake  Erie  drain¬ 
age,  characterized  by  shale-bottomed  streams,  often  in  deep  valleys,  and  the  Ohio  drainage,  with 
meandering,  gravel-bottomed  streams.  Erie  County  is  within  the  southern  boundary  of  the  Late 
Wisconsinan  Glaciation,  which  produced  several  lakes,  swamps,  and  bogs  in  the  region.  The  pen¬ 
insula  of  Presque  Isle  State  Park  on  the  Lake  Erie  shoreline  is  a  distinctive  feature  of  the  landscape 
that  hosts  a  number  of  species  that  do  not  occur  elsewhere  in  the  county. 

The  purpose  of  this  work  is  to  provide  a  thorough  summary  of  the  current  state  of  knowl¬ 
edge  regarding  the  county’s  amphibians  and  reptiles.  We  used  our  field  notes,  correspondence  with 
reliable  persons,  and  the  published  and  unpublished  literature  pertinent  to  Erie  County.  Each  species 
account  contains  the  following  information  (if  available):  known  species  distribution  in  the  county, 
earliest  and  latest  annual  dates  of  observation,  natural  history  information,  and  a  list  of  museum 
specimens  collected  from  Erie  County.  The  following  museum  collection  records  were  consulted  to 
generate  the  lists  of  specimens:  American  Museum  of  Natural  History  (AMNH),  Carnegie  Museum 
of  Natural  History  (CM),  Cleveland  Museum  of  Natural  History  (CMNH),  Edinboro  University  of 
Pennsylvania  (EUP),  Museum  of  Comparative  Zoology  (MCZ),  University  of  Colorado  Museum, 
Boulder  (UCM),  University  of  Michigan  Museum  of  Zoology  (UMMZ),  State  Museum  of  Penn¬ 
sylvania  (SMP),  Sternberg  Museum  of  Natural  History  (MHP),  The  Natural  History  Collections  of 
the  Tom  Ridge  Environmental  Center  at  Presque  Isle  (TREC),  the  United  States  National  Museum 
(USNM),  and  Gannon  University  (GU).  In  addition  to  these,  one  of  the  authors’  (BG)  personal  col¬ 
lection  of  shed  snake  skins  was  also  used.  An  asterisk  represents  mounted  shed  skin  material  is  in 
the  Brian  S.  Gray  collection,  and  unmounted  material  from  the  same  specimen  is  in  the  Sternberg 
Museum  of  Natural  History.

The  bibliography  at  the  end  of  this  work  is  meant  to  provide  a  comprehensive  list  of 
publications  that  are  pertinent  to  the  herpetology  of  Erie  County. 

The  Pennsylvania  Fish  and  Boat  Commission  is  responsible  for  regulations  pertaining  to 
reptiles  and  amphibians  in  the  state.  The  following  Erie  County  reptile  and  amphibian  species  have 
no  open  season:  Eastern  Hognose  Snake  ( Heterodon platirhinos ),  Eastern  Ribbon  Snake  ( Thamnophis 
sauritus ),  Queen  $nak&(Regina  septemvittata ),  Shorthead  Garter  Snake  ( Thamnophis  brachy stoma). 
Smooth  Green  Snake  ( Liochlorophis  vernalis ),  Eastern  Hellbender  ( Cryptobranchus  alleganiensis 
alle  gardens  is).  Four-toed  Salamander  ( Hemidactylium  scutatum),  Jefferson  Salamander  (. Ambystoma 
jejfersonianum) ,  Mudpuppy  (. Necturus  maculosus ),  Striped  Chorus  Frog  Complex  ( Pseudacris 
triseriata  ssp.),  B landing's  Turtle  ( Emydoidea  blandingii ),  Eastern.  Box  Turtle  ( Terrapene  Carolina 
Carolina),  Spotted  Turtle  ( Clemmys  guttata),  and  Wood  Turtle  ( Glyptemys  insculpta ).  The  daily  limit 
is  zero,  and  possession  limit  is  zero  on  these  species.  They  may  be  possessed  only  with  a  permit 
issued  by  the  Commission  (Pennsylvania  Fish  and  Boat  Commission,  2007.  Pennsylvania  Fishing 
Summary,  Summary  of  Fishing  Regulations  and  Laws).  If  a  specimen  of  any  of  these  species  is 
found  in  Erie  County,  good  quality  photographs  showing  diagnostic  characters  should  be  taken,  and 
the  observation  should  be  reported  to  the  Pennsylvania  Online  Herpetological  Atlas(http://webspace. 
ship.edu/tjmare/herp.htm).  Additionally,  the  authors  are  interested  in  observations  of  these  species 
in  the  county  and  may  be  contacted  directly. 


AmpMMfins, 


Twenty-two  species  of  amphibians  have  been  reported  to  occur  in  Erie  County.  However, 
two  of  these  species  -  Eurycea  longicauda  and  Pseudacris  triseriata  -  are  undocumented. 

Salamanders  are  the  most  diverse  group  of  amphibians  to  occur  in  Erie  County  and  are 
represented  by  13  species. 

Eastern  Hellbender,  Cryptobranchus  alleganiensis  alleganiensis.  The  Eastern  Hellbender 
is  an  inhabitant  of  streams  with  a  moderate  to  swift  current,  and  a  gravel  or  sandy  bottom  with  large 
flat  rocks  (Hulse  et  al  2001).  In  Erie  County  it  is  an  uncommon  salamander,  being  found  only  in  the 
French  Creek  watershed.  This  species  has  been  found  in  Amity,  LeBoeuf,  and  Waterford  Townships. 
A  sample  of  ten  Erie  County  specimens  had  a  mean  TL  of  421.8  mm  (sd=53.8,  range  305-508). 
This  species  has  been  observed  between  21  June  and  10  September,  but  due  to  its  aquatic  nature, 
it  is  likely  to  be  active  in  all  months. 

Specimens:  UMMZ  75981 

Mudpuppy,  Necturus  maculosus  maculosus .  The  Mudpuppy  is  found  in  Lake  Erie  and 
Presque  Isle  Bay,  and  has  also  been  found  in  Amity,  Conneaut,  LeBoeuf,  North  East  (Lake  Erie 
shoreline),  Springfield,  Venango,  Washington  and  Waterford  townships.  Inland  populations  are  ap¬ 
parently  restricted  to  Conneaut  Creek  and  the  French  Creek  drainage.  Swanson  (1948)  stated  that 
he  had  taken  mudpuppies  at  the  outlet  of  Edinboro  Lake.  In  2002,  a  massive  die-off  of  mudpuppies 
occurred  in  Lake  Erie,  which  was  attributed  to  an  outbreak  of  botulism  (Bartlett,  2002).  A  total  of 
712  dead  mudpuppies  were  counted  along  less  than  one  mile  of  shoreline  in  North  East  Township 
on  30  June  2002.  On  14  July  1997,  eggs  (n=17)  were  found  attached  to  the  bottom  of  a  rock  in 
French  Creek.  Mudpuppies  have  been  taken  in  a  trawl  net  from  Lake  Erie  by  the  Pennsylvania  Fish 
and  Boat  Commission  at  a  depth  of  17.4  m  (57  ft).  The  Mudpuppy  has  been  observed  between  15 
April  and  10  October  in  Erie  County,  but  like  the  Hellbender  it  may  be  active  in  all  months.

Jefferson  Salamander,  Ambystoma  jejfersonianum.  The  Jefferson  Salamander  is  uncom¬ 
mon  in  Erie  County,  being  known  from  sites  in  Amity,  Harborcreek,  Millcreek,  North  East,  and 
Union  townships.  An  environmental  impact  study  (Aquatic  Ecology  Associates,  1977a,  b)  of  what 
is  now  State  Game  Lands  314,  and  property  east  of  Conneaut  Creek  in  Ohio  reported  A.  jejferso¬ 
nianum  from  along  Turkey  Creek  in  Ashtabula  County.  Additional  surveys  are  needed  to  determine 
whether  this  species  occurs  in  Springfield  Township.  The  Jefferson  salamander  needs  hardwood  or 
mixed  forest  with  vernal  pools  in  which  to  breed.  Ambystoma  jejfersonianum  is  usually  observed 
during  the  spring  breeding  season,  and  adults  are  rarely  encountered  outside  this  season.  Five  Erie 
County  A.  jejfersonianum  had  an  average  SVL  of  76.6  mm  (sd=0.9,  range  75-77),  and  TL  of  157.2 
mm  (sd=l.l,  range  156-159).  In  Erie  County,  Jefferson  Salamanders  have  been  observed  from  27 
February  to  15  June.

Reptiles, 

Twenty  -  three  reptile  species  are  known  to  occur  in  Erie  County.  Snakes  are  the  most 
diverse  group  and  are  represented  by  thirteen  species.  However,  the  Eastern  Hognose  Snake  may 
have  been  extirpated  from  the  county. 

Queen  Snake,  Regina  septemvittata.  The  Queen  Snake  is  primarily  an  inhabitant  of 
lotic  habitats.  The  streams  where  R.  septemvittata  is  found  usually  are  lined  with  shrubs  and  small 
trees,  in  which  these  snakes  bask.  Crayfish,  the  Queen  Snake’s  primary  food,  is  also  a  necessary 
component  of  the  habitat.  In  Erie  County,  the  Queen  Snake  is  known  from  Elk  Creek  and  Con¬ 
neaut  Creek  in  the  following  townships:  Conneaut,  Girard,  McKean,  Millcreek  (Presque  Isle),  and 
Springfield.  The  Presque  Isle  specimen  (CM  1936)  was  collected  in  1906  by  Atkinson.  McPherson 
(1982)  also  reported  this  species  from  Presque  Isle.  However,  recent  surveys  at  Presque  Isle  have 
not  found  Regina  septemvittata  (McKinstry  et  al,  1991 ;  Hughes  and  Schnars,  2007).  Queen  Snakes 
in  Erie  County  have  been  observed  between  14  May  and  25  September.  McKinstry  and  Felege 
(1974)  caught  a  specimen  that  was  35  cm  TL,  and  weighed  8  grams.  Scott  Bloomstine  (pers.  com.) 
collected  a  female  from  McKean  Township  that  gave  birth  to  10  neonates  during  the  first  week  of 
September.

Northern  Water  Snake,  Nerodia  sipedon  sipedon.  This  species  is  common  throughout 
the  county,  and  likely  occurs  in  all  townships.  It  has  been  observed  from  Amity,  Concord,  Fairview, 
Girard,  Greene,  Greenfield,  Harborcreek,  LeBoeuf,  McKean,  Millcreek,  North  East,  Springfield, 
Union,  Washington  and  Waterford  Townships.  Although  it  is  more  frequently  encountered  along 
the  edges  of  streams,  Nerodia  s.  sipedon  may  be  found  along  lakes,  ponds,  swamps,  and  vernal 
pools.  On  6  May  2004,  a  “mating  ball”  was  observed  at  Asbury  Woods  in  a  buttonbush  wetland. 
The  “ball”  consisted  of  four  males  attempting  to  copulate  with  a  female.  Scott  Bloomstine  (pers. 
comm.)  reported  a  female  that  gave  birth  to  26  neonates  during  August  2004.  The  largest  known 
litter  from  an  Erie  County  N.  sipedon  was  38  neonates.  McKinstry  and  Felege  (1974)  reported  an 
average  total  length  of  57  cm  (range  30-106  cm),  for  fifteen  specimens  from  Erie  County.  Northern 
Water  Snakes  have  been  observed  from  31  March  to  15  November  in  Erie  County.

Northern  Brown  Snake,  Storeria  dekayi  dekayi.  This  species  is  common  in  areas  that 
contain  old  field  habitat  in  Erie  County,  even  in  urban  and  disturbed  areas.  The  Northern  Brown 
Snake  has  been  found  in  the  City  of  Erie;  at  Presque  Isle  State  Park;  and  in  Amity,  Concord,  Con 
neaut,  Girard,  Greenfield,  Harborcreek,  LeBoeuf,  McKean,  Millcreek,  North  East,  Springfield, 
Union,  Venango,  Waterford,  and  Wayne  Townships.  Litters  from  three  Erie  County  females  ranged 
from  10-19  (Table  1).  McKinstry  and  Felege  (1974)  reported  an  average  TL  of  280  mm  (range  130 
-380  mm)  for  twenty  eight  Erie  County  specimens  Average  weight  for  these  same  specimens  was 
8  grams  (range  1-22  g).  Our  sample  of  Erie  County  specimens  (n=27)  averaged  227.6  mm  SVL 
(sd=42,  range  1 19.2-304),  and  290.3  mm  TL  (sd=50.4,  range  155.8-382);  weight  for  fifteen  Millcreek 
specimens  averaged  6.7  g  (sd-4.0,  range  3-14.25).  Dates  of  parturition,  with  litter  size  in  parentheses 
for  three  Erie  County  individuals  was  13  August  (10),  16  August  (17),  and  20  August  (19). 

Northern  Brown  Snakes  in  Erie  County  have  been  observed  as  early  as  6  January  and  as 
late  as  4  November.

Northern  Red  belly  Snake,  Storeria  occipitomaculata  occipitomaculata.  This  species 
is  common  in  wooded  and  ecotone  areas  where  forest  and  old  fields  converge.  The  Northern  Red- 
belly  Snake  has  been  observed  in  Amity,  Greene,  Harborcreek,  LeBoeuf,  Millcreek,  Northeast, 
Springfield,  Summit,  Union,  Venango,  Waterford,  and  Wayne  Townships.  This  species  has  also 
been  found  in  the  city  of  Erie  (Bob  Wellington  pers.  comm.).  A  female  gave  birth  to  8  neonates  on 
27  July  2002;  neonates  were  66  -  68  mm  SVL  and  86  -  90  mm  TL.  McKinstry  and  Felege  (1974) 
report  an  average  TL  of  300  mm  (range  250  -  350  mm)  for  ten  Erie  County  specimens.  Five  ad¬ 
ditional  Erie  County  individuals  averaged  246  mm  SVL  (sd=14,  range  234.9-267.5),  and  303.6  TL 
(sd  - 19.  7,  range  291-338.1).  Melanistic  individuals  have  been  found  near  West  Springfield  and  west 
of  the  Erie  International  Airport.  Northern  Red  belly  Snakes  have  been  observed  from  30  March 
to  28  October  in  Erie  County.

Shorthead  Garter  Snake,  Thamnophis  brachystoma.  The  Shorthead  Garter  Snake 
prefers  open  habitats  with  low  herbaceous  cover,  such  as  meadows  and  old  fields,  and  is  rarely 
found  within  densely  forested  areas.  The  Shorthead  Garter  Snake  has  been  found  within  the  City 
of  Erie,  at  Presque  Isle  State  Park,  and  in  Amity,  Millcreek,  Springfield,  Summit,  Union,  and  Wayne 
Townships.  Thamnophis  brachystoma  appears  to  be  more  common  in  the  eastern  two  thirds  of 
the  county,  and  at  a  few  sites  is  abundant.  It  has  been  assumed  by  several  authors  (Conant,  1975; 
Price,  1978;  McCoy,  1982;  Hulse  et  al  2001)  that  the  urban  Erie  County  populations  of  this  species 
were  introductions.  Price  (1978)  considered  the  absence  of  intervening  populations  between  the 
“natural”  range  and  the  supposed  introductions  as  support  for  the  human  introduction  hypothesis. 
However,  new  T  brachystoma  sites  in  Erie  County  have  been  located,  and  are  30  -  72  km  west  of 
the  glacial  boundary  (Gray,  2008b).  Furthermore,  some  of  the  new  sites  are  located  between  the

supposed  introductions  and  the  “natural”  populations  as  described  by  Price  (1978).  In  light  of  the 
recently  discovered  sites,  it  may  be  necessary  to  consider  alternatives  to  anthropogenic  introduction 
as  explanation  for  the  presence  of  this  species  in  rural  glaciated  areas.  Two  possible  interpretations 
are  that  the  range  of  T  brachystoma  has  expanded,  or  is  expanding,  or  that  the  species  once  had 
a  range  that  was  more  extensive,  and  has  since  contracted.  Litter  sizes  for  Erie  County  specimens 
range  from  6  to  17  neonates.  Thamnophis  brachystoma  in  Erie  County  has  been  observed  from  29 
March  -  10  October.  Specimens:  AMNH  105886  -  105888;  BG  032;  BG  043;  BG  046*;  BG  089*;

Northern  Ribbon  Snake,  Thamnophis  sauritus  septentrionalis.  Northern  Ribbon  Snakes 
are  most  often  found  near  or  within  aquatic  habitats  such  as  lakes,  marshes,  swamps,  and  ponds. 
Thamnophis  s.  septentrionalis  is  only  known  from  a  few  localities  in  Erie  County,  having  been 
found  at  Presque  Isle  State  Park,  and  in  Girard,  Greene,  Millcreek,  Union,  and  Waterford  Townships. 
McKinstry  and  Felege  (1974)  reported  an  average  TL  of  70  cm  (range  42  -  96  cm)  and  an  average 
weight  of  57  grams  (range  9  -  120  g)  for  five  Erie  County  specimens.  Erie  County  T,  sauritus  have 
been  observed  9  May  to  26  November.  We  have  observed  Northern  Ribbon  Snakes  active  in  neigh¬ 
boring  Crawford  County  in  late  March.  McKinstry  (1975)  noted  that  Ribbon  Snakes  at  Presque  Isle 
State  Park  were  particularly  “abundant”  during  sunny  days  in  October.  A  Northern  Ribbon  Snake 
captured  on  8  July  2007  in  Waterford  Township  produced  a  litter  of  24  young  on  2  Aug  2007.  This 
is  two  less  than  the  maximum  recorded  litter  size  (26)  for  the  species,  and  is  substantially  higher 
than  the  maximum  of  13  for  Pennsylvania  specimens  (N=8)  noted  by  Hulse  et  al  (2001).

Eastern  Garter  Snake,  Thamnophis  sirtalis  sirtalis.  The  Eastern  Garter  Snake  is  a 
common  snake  in  Erie  County,  and  can  be  found  in  a  wide  variety  of  habitats,  including  old  fields, 
meadows,  forest  edges,  along  streams  and  other  bodies  of  water.  It  has  been  found  in  the  City  of 
Erie,  and  Amity,  Concord,  Coeneaut,  Fairview,  Girard,  Greene,  Greenfield,  Harborcreek,  LeBoeuf, 
McKean,  Millcreek,  North  East,  Springfield,  Summit,  Union,  Venango,  Washington,  Waterford,  and 
Wayne  Townships.  Melanistic  individuals  are  known  to  occur  at  Presque  Isle  State  Park.  Litter 
sizes  for  Erie  County  females  range  from  8  -  50,  with  dates  of  parturition  being  between  14  July 
and  31  August.  McKinstry  and  Felege  (1974)  reported  an  average  TL  of  490  mm  (range  160-730 
mm),  and  an  average  weight  of  41  grams  (range  20  -  161  g)  for  93  Erie  County  specimens.  Our 
Erie  County  sample  averaged  386.8  mm  SVL  (n=26,  sd=110.8,  range  205-648),  and  495.9  mm  TL 
(n=25,  sd=132.9,  range  260-795).  Gray  et  al  (2001,  2003)  reported  on  anomalies  observed  in  the 
litters  of  females  collected  from  a  Millcreek  Township  population.  Thamnophis  sirtalis  has  been 
observed  between  27  March  and  1  December  in  Erie  County.

Eastern  Hognose  Snake,  Heterodon  platirhinos.  The  Eastern  Hognose  Snake  prefers 
areas  with  sandy  soils  in  which  it  can  burrow.  These  sites  may  be  open  or  forested.  In  Erie  County, 
the  Eastern  Hognose  Snake  is  only  known  from  Presque  Isle  State  Park,  where  it  has  almost  certainly 
been  extirpated.  The  last  specimen  was  collected  from  the  park  in  1933,  by  R.  R.  Carr.  Carnegie 
Museum  of  Natural  History  records  indicate  that  H.  platirhinos  has  been  collected  between  5  June 
and  13  September  at  Presque  Isle  State  Park. 

Specimens:  CM  472;  CM  1519;  CM  1980  -  1983;  CM  2028;  CM  2029;  CM  6618 

Northern  Ringneck  Snake,  Diadophis  punctatus  edwardsii.  The  Northern  Ringneck 
Snake  is  known  from  Amity,  Conneaut,  Greene,  Harborcreek,  Millcreek,  North  East,  Union,  and 
Waterford  Townships.  Diadophis  p.  edwardsii  is  common  at  most  of  the  known  localities  in  Erie 
County,  especially  in  wooded  areas  with  plenty  of  cover  and  plethodontid  salamanders,  this  species’ 
preferred  prey.  McKinstry  and  Felege  (1974)  reported  an  average  TL  of  35  cm  (range  18-42  cm) 
and  an  average  weight  of  9  grams  (range  2  -  16  g)  for  six  Erie  County  specimens.  Our  Erie  County 
sample  averaged  284.7  mm  SVL  (n=5,  sd=48.3,  range  227.3-350),  TL  averaged  363.6  mm  (n=5, 
sd=54,  range  302.1-434.6),  mean  weight  was  7.6  g  (n=5,  sd=4.6,  range  3-15).  In  Erie  County 
Diadophis  p.  edwardsii  has  been  observed  between  6  April  and  30  September.

Northern  Black  Racer,  Coluber  constrictor  constrictor.  Harold  Surface  (1906)  reported 
that  he  had  received  a  specimen  from  Waterford.  This  species  may  have  been  extirpated  from  the 
county,  or  if  it  occurs  in  the  county,  it  is  rare  and  occurs  in  isolated  populations.  Coluber  constrictor 
constrictor  has  been  found  in  adjacent  Ashtabula  County,  Ohio  (Morgan  and  Rome  Townships)  as 
recently  as  1980  (Wynn  and  Moody,  2006). 

In  Pennsylvania,  Northern  Black  Racers  inhabit  old  fields,  meadows  and  agricultural 
areas,  and  may  be  active  from  mid- April  to  late  October  (Hulse  et  al.  2001).  These  snakes  are 
diurnal  and  not  found  under  cover  as  often  as  other  species  (Hulse  et  al  2001),  and  therefore,  may 
not  be  as  readily  detected  using  coverboards.  If  a  specimen  is  found  in  Erie  County,  it  should  be 
retained  for  verification  by  a  herpetologist,  or  alternatively  a  good  quality  photograph  should  be 
taken  (preferably  with  a  close  view  of  the  body  scales),  and  submitted  to  a  herpetologist  or  the 
Pennsylvania  Online  Herpetological  Atlas. 

Smooth  Green  Snake,  Liochlorophis  vernalis.  The  Smooth  Green  Snake  is  found  in 
open  fields,  meadows,  and  ecotones.  Liochlorophis  vernalis  is  known  from  Amity,  North  East, 
Springfield,  and  Waterford  Townships.  Surface  (1906)  lists  E.  A.  Baron  as  providing  a  specimen 
from  McKean.  On  9  August  1999,  a  nest  with  seven  eggs  was  found  in  a  cavity  beneath  a  board  at 
a  Springfield  Township  site.  Six  Erie  County  specimens  averaged  306.5  mm  SVL  (sd=41.5,  range 
248-370.5),  and  442  mm  TL  (sd=49.8,  range  367-510).  In  Erie  County  Liochlorophis  vernalis  has 
been  observed  5  April  to  28  October.

Eastern  Rat  Snake,  Elaphe  alleghaniensis.  The  Eastern  Rat  Snake  is  found  in  decidu¬ 
ous  forest,  ecotonal  areas,  and  frequently  in  old  dilapidated  bams.  Elaphe  alleghaniensis  is  known 
from  only  a  few  sites  in  Erie  County:  from  within  the  City  of  Erie,  as  well  as  Conneaut,  Fairview, 
Millcreek,  North  East,  and  Springfield  townships.  Surface  (1906)  reported  specimens  from  Miles 
Grove  and  North  East.  An  Erie  County  specimen  was  1120  mm  SVL  and  1320  mm  TL.  The  Eastern 
Rat  Snake  has  been  observed  in  Erie  County  from  21  April  to  13  October.

common  in  Erie  County,  and  is  reported  from  the  City  of  Erie,  Amity,  Fairview,  Girard,  Greene, 
Greenfield,  Harborcreek,  McKean,  Millcreek,  Springfield,  Union,  and  Wayne  Townships.  Lampro¬ 
peltis  t.  triangulum  is  usually  found  under  debris  in  open  fields,  meadows,  or  ecotones.  On  13  July 
1997,  a  female  (750  mm  SVL;  848  mm  TL)  collected  from  a  Millcreek  Township  site  deposited 
eleven  eggs,  which  hatched  3  September.  The  weight  of  hatchlings  (6  females  :5  males)  averaged 
4.1  grams.  McKinstry  and  Felege  (1974)  reported  an  average  TL  of  490  mm  (range  230  -910  mm) 
for  seventeen  specimens  from  Erie  County.  Our  sample  of  Erie  County  L.  t.  triangulum  averaged 
684.3  mm  SVL  (n=6,  sd=78.3,  range  615-811),  and  814.8  mm  TL  (n=7,  sd=99.8,  range  725-960). 
Eastern  Milk  Snakes  in  Erie  County  have  been  observed  from  28  April  to  10  October.

There  is  only  a  single  lizard  species  found  in  Erie  County 

Five-lined  Skink,  Eumeces  fasciatus.  In  Erie  County,  the  Five-lined  Skink  is  found  in 
old  fields  and  ecotonal  areas  between  field  and  forest.  This  species  is  known  only  from  a  few  sites 
in  Conneaut  and  Springfield  Townships.  On  22  May  1991,  two  Five-lined  Skinks  were  observed 
mating  on  abandoned  railroad  bridge  in  Conneaut  Township.  The  female  was  maintained  in  cap¬ 
tivity,  and  produced  nine  eggs  on  21  June,  eight  of  which  hatched  on  21  July.  A  female  was  found 
brooding  eleven  eggs  in  a  cavity  beneath  a  piece  of  tin  on  4  August  1997  in  Springfield  Township. 
A  female  captured  27  June  2003  in  Conneaut  Township  produced  12  eggs  in  captivity  on  12  July, 
11  of  which  hatched  on  12  Aug.  Three  Springfield  Township  Five-lined  Skinks  averaged  68  mm 
SVL  (sd=7.0,  range  61-75),  TL  averaged  166.7  mm  (sd=9.1,  range  157-175).  Erie  County  Eumeces 
fasciatus  have  been  observed  from  29  March  -  29  September.

There  are  nine  turtle  species  known  to  occur  in  Erie  County. 

Wood  Turtle,  Glyptemys  insculpta .  The  Wood  Turtle  is  a  streamside  species,  and  often 
utilizes  nearby  woods,  meadows,  and  old  fields.  Glyptemys  insculpta  were  collected  from  “near 
Erie,  Presque  Isle”  In  1933  and  “Erie  Harbor”  in  1934.  Considering  the  strong  association  of  this 
species  with  stream  habitats,  it  seems  unlikely  that  Wood  Turtles  ever  existed  on  the  peninsula  of 
Presque  Isle  in  an  established  population.  It  is  probable  that  if  a  population  occurred  around  Presque 
Isle  Bay,  it  was  In  the  vicinity  of  some  of  the  streams  entering  the  bay,  such  as  Cascade  Creek.  No 
additional  specimens  have  been  documented  in  the  county.  Garber  and  Burger  (1995)  documented 
the  extirpation  of  a  Connecticut  Wood  Turtle  population  following  the  permitting  of  hiking  and 
fishing  In  an  area  that  was  formerly  closed  to  the  public.  There  have  been  occasional  unsubstanti¬ 
ated  reports  of  this  species  in  the  French  Creek  Watershed  in  the  eastern  portion  of  Erie  County.

Further  work  is  needed  to  confirm  the  presence  of  this  species  in  that  area.  Both  specimens  in  the 
Carnegie  Museum  of  Natural  History  were  collected  in  August. 

Specimens:  CM  6880;  CM  7503 

Common  Snapping  Turtle,  Chelydra  serpentina  serpentina.  The  Common  Snapping 
Turtle  is  found  in  a  wide  variety  of  habitats,  from  vernal  pools  to  large  lakes  and  streams.  The 
Common  Snapping  Turtle  has  been  found  at  Presque  Isle  State  Park,  and  in  Amity,  Conneaut, 
Girard,  Elk  Creek,  Fairview,  Girard,  McKean,  Millcreek,  Springfield,  Union,  Venango,  Washing¬ 
ton,  Waterford,  and  Wayne  Townships.  Ten  Erie  County  Common  Snapping  Turtles  averaged  237 
mm  CL  (sd=85.1,  range  101-381).  Chelydra  s.  serpentina  has  been  observed  from  29  March  to  9 
September  in  Erie  County.

Common  Musk  Turtle,  Sternotherus  odoratus.  The  Common  Musk  Turtle  in  Erie  County 
is  known  from  Presque  Isle  State  Park  in  Millcreek  Township,  and  possibly  Springfield  Township 
(Aquatic  Ecology  Associates,  1977a).  Matson  et  al  (2004)  found  a  specimen  in  Conneaut  Creek  in 
Ohio,  near  the  Ohio  -  Pennsylvania  border.  Due  to  high  water  conditions  the  previous  week,  they 
suggested  that  it  may  have  been  swept  downstream  from  Pennsylvania  waters;  therefore  it  is  pos¬ 
sible  that  this  species  occurs  in  Conneaut  or  Springfield  Townships  in  Erie  County  as  well.  Eighteen 
Common  Musk  Turtles  from  Presque  Isle  averaged  103.1  mm  CL  (sd=9.2,  range  83-114);  weight 
averaged  184.9  g  (n=14,  sd=48.6,  range  106-245).  Sternotherus  odoratus  has  been  observed  from 
24  April  to  30  September. 

Specimens:  CM  3185;  CM  7500;  CM  7501;  CM  21740;  EUP  112;  EUP  148 

Spotted  Turtle,  Clemmys  guttata .  The  Spotted  Turtle  is  uncommon  in  Erie  County,  hav¬ 
ing  been  found  only  in  the  western  half  of  the  county,  including  Presque  Isle.  This  species  prefers 
more  shallow  habitats,  such  as  vernal  pools,  marshes,  small  slow-flowing  creeks,  and  occasionally, 
the  shallow  edges  of  ponds  and  lakes.  Carapace  length  of  Erie  County  Spotted  Turtles  ranged  from 
80.7  -  121.8  mm  (X  =  106.5;  sd  =  8.1 ;  n  =  20)  in  males,  and  85.5  -  1 14.8  mm  (X  =  105.6;  sd  =  7.6; 
n  =  18)  in  females.  Weight  of  these  same  turtles  was  88-225  grams  (X  =  174.4;  sd  =  31.5;  n  =  20) 
in  males,  and  92-241  grams  (X  =  189.7;  sd  =  36.1;  n  =  18)  in  females. 

A  western  Erie  County  population  was  estimated  to  contain  35  -  45  (95%  confidence 
interval)  adult  turtles  (Gray,  2004).  The  Spotted  Turtle  in  Erie  County  has  been  observed  between 
26  February  and  20  July.  In  adjacent  Crawford  County,  Clemmys  guttata  have  been  seen  active  as 
late  as  early  October  (Anderson  and  Stull,  1995.) 

Specimens:  CM  3204;  CM  7502 

Blanding’s  lYirtle,  Emydoidea  blandingii.  This  species  is  rare  in  Erie  County,  and  is  only 
known  from  Presque  Isle  State  Park,  the  only  site  in  Pennsylvania  where  this  species  is  currently 
known  to  occur.  Emydoidea  blandingii  is  usually  found  in  habitats  containing  a  mosaic  of  inter¬ 
connected  habitats,  such  as  marshes,  wet  meadows,  ponds,  and  slow  moving  streams  (Hulse  et  al. 
2001).  Sightings  of  E.  blandingii  have  been  made  between  24  April  (R.  Grubbs,  pers.  comm.)  and 
September  (Anderson,  1983).  Hulse  et  al  (2001)  considered  specimens  at  Presque  Isle  as  possible 
waifs  from  other  populations.  However,  the  recent  increase  in  sightings  of  at  least  five  different 
individuals  at  the  park  suggests  that  this  might  not  be  the  most  parsimonious  explanation.  The  status 
of  this  species  at  Presque  Isle  is  in  need  of  additional  study.

Eastern  Box  Turtle,  Terrapene  Carolina  Carolina.  The  Eastern  Box  Turtle  is  rare  and  may 
be  extirpated  from  Erie  County.  Terrapene  c.  Carolina  is  reportedly  most  often  found  in  decidu¬ 
ous  forest  and  ecotonal  areas  between  forest  and  old  field  (Hulse  et  al  2001).  It  has  been  recorded 
from  Presque  Isle  State  Park,  and  also  from  Fairview  and  Millcreek  Townships.  However,  the 
recent  observations  of  this  species  in  Fairview  and  Millcreek  were  most  likely  released  pets.  When 
captured,  the  Fairview  individual  did  not  display  the  typical  defensive  behavior  of  this  species 
-  withdrawal  into  the  shell. 

The  specimens  in  the  Carnegie  Museum  were  collected  between  7  June  and  August. 

Specimens:  CM  3168;  CM  7504 

Common  Map  TUrtie,  Graptemys  geographica.  In  Erie  County,  the  Common  Map  Turtle 
is  found  in  Presque  Isle  State  Park  and  Presque  Isle  Bay,  and  occasionally  along  the  Lake  Erie  shore¬ 
line  to  North  East,  especially  in  protected  harbors.  It  has  been  introduced  to  Edieboro  Lake.  Records 
exist  for  the  City  of  Erie  and  the  townships  of  Fairview,  Millcreek,  North  East  and  Washington.  At 
Presque  Isle,  the  Common  Map  Turtle  is  abundant.  The  Common  Map  Turtle  prefers  large  bodies 
of  water,  such  as  rivers  and  lakes  with  basking  sites  that  provide  access  to  deep  water.  A  sample 
of  twenty-seven  male  Common  Map  Turtles  from  Presque  Isle  averaged  110.4  mm  CL  (sd=12.2, 
range  58-130);  male  mass  averaged  172  g  (n=17,  §d=22.7,  range  133-217);  females  averaged  220.9 
mm  CL  (n=18,  sd=20.9,  range  172-245);  female  mass  averaged  1380.9  g  (n=18,  sd=374.4,  range 
587-2079).  Graptemys  geographica  has  been  observed  from  29  February  to  4  November.

Midland  Painted  Turtle,  Chrysemys  picta  marginata.  The  Midland  Painted  Turtle  has 
been  found  in  just  about  every  type  of  aquatic  habitat  in  Erie  County,  including  swamps,  marshes, 
vernal  pools,  and  man-made  ponds  to  name  just  a  few.  Chrysemys  p.  marginata  is  a  common  species 
in  Erie  County.  It  has  been  observed  at  Presque  Isle  State  Park,  and  in  Amity,  Conneaut,  Fairview, 
Greene,  Greenfield,  Harborcreek,  McKean,  Millcreek,  Springfield,  Union,  Venango,  Washington, 
and  Waterford  Townships.  Males  from  Erie  County  average  119.2  mm  CL  (n=27,  sd-14.1,  range 
92-141);  while  females  averaged  124.2  mm  (n-20,  sd=26.8,  range  78-155.5).  Juveniles  from  Mill¬ 
creek  Township  (n=6)  averaged  60  mm  CL  (sd  10,6,  range  50-78.3).  Mass  for  five  adults  averaged 
268.6  g  (sd=50.6,  range  201-325).  Chrysemys  p.  marginata  has  been  observed  in  every  month  in 
Erie  County,  with  the  earliest  date  being  6  January,  and  the  latest  being  7  December. 

Specimens:  CM  3009 -3011;  CM  3039;  CM  3080;  CM  3151;  CM  3175;  CM  3218;  CM

Eastern  Spiny  Softshell,  Apalone  spinifera  spinifera.  The  Eastern  Spiny  Softshell  is 
uncommon  in  Erie  County,  and  has  been  found  at  Presque  Isle  State  Park,  as  well  as  in  the  Con¬ 
neaut  Creek  drainage  in  Conneaut  and  Springfield  townships,  and  in  the  French  Creek  drainage  in 
Greene,  LeBoeuf,  Washington,  and  Waterford  Townships.  In  Erie  County,  Apalone  s.  spinifera  has 
been  observed  between  1 3  April  and  5  August. 

Specimens:  CM  1321;  CM  3012;  CM  3038;  CM  3192;  CM  3222;  CM  43865;  EUP  2-6

Longtail  Salamander,  Eurycea  longicauda  longicauda.  Hulse  et  al  (2001)  show  the  likely 
distribution  of  this  species  as  including  all  of  Erie  County.  However,  there  are  no  museum  specimens, 
nor  literature  records  for  this  species  in  Erie  County  (McCoy  1982).  In  Ohio,  the  closest  record  to 
Erie  County  is  in  southeastern  Ashtabula  County  (Pfingsten  and  Matson  2003);  in  New  York  the  range 
only  extends  to  southeastern  Chautauqua  County  (Gibbs  et  al.  2007).  A  recent  survey  of  amphibians 
and  reptiles  along  Conneaut  Creek  in  Ashtabula  County,  Ohio  failed  to  find  any  Eurycea  longicauda 
(Matson  et  al  2004).  In  addition,  the  authors  of  the  current  paper  have  spent  a  considerable  amount 
of  time  in  the  field  throughout  Erie  County  and  have  not  observed  this  species. 

Western  Chorus  Frog,  Pseudacris  triseriata  triseriata.  Like  the  Longtail  Salamander, 
the  range  of  the  Western  Chorus  Frog  has  been  illustrated  as  including  Erie  County  (Conant  and 
Collins  1998;  Hulse  et  al  2001).  No  museum  specimens  and  no  literature  records  are  known  from 
Erie  County  (McCoy  1982).  The  Western  Chorus  Frog  is  known  from  southeastern  Cattaraugus 
County,  New  York  (Gibbs  et  al  2007)  and  southeastern  Ashtabula  County,  Ohio  (Davis  and  Menze 
2000).  Pseudacris  t.  triseriata  is  reported  to  be  somewhat  tolerant  of  human-altered  landscapes,  as 
long  as  pollution  is  not  severe  (Conant  and  Collins  1998).  This  diminutive  anuran  should  be  sought 
in  swamps,  marshes,  and  water-filled  roadside  ditches,  especially  in  border  regions  in  Concord, 
Conneaut,  Springfield,  and  Wayne  townships. 

Nonnatke_SpedesA, 

The  following  are  examples  of  nonnative  amphibian  and  reptile  taxa  that  have  been  found 
in  Erie  County:  Chrysemys  picta  picta,  Terrapene  Carolina  triunguis,  Terrapene  ornata  (McKinstry, 
1987),  Trachemys  scripta  elegans,  Anolis  carolinenis,  Rhamphotyphlops  hraminus  (Paul  Curtis,  pers. 
comm.),  Caiman  crocodilus  (McKinstry,  1987).  Graptemys  pseudo  geo graphica  (Robert  Wellington, 
Peter  Lindeman,  pers.  comm.),  and  Osteopilus  septentrionalis  (Mike  Dohanic,  pers.  comm.). 

Most  of  these  specimens  were  released  or  escaped  pets,  although  some  arrive  as  stowaways 
in  shipments  of  products.  Most  of  these  species  are  unlikely  to  become  established,  as  they  are  not 
adapted  to  survive  the  harsh  winters,  but  a  few  could  potentially  establish  in  the  county  (e.g.  the 
Red-eared  Slider).  Nonnative  species  and  released  pets  present  several  threats  to  native  species, 
such  as  the  potential  to  introduce  disease  or  genes  into  populations  where  their  introduction  would 
be  detrimental.  They  may  also  compete  with  native  populations,  possibly  causing  declines. 

Statm^and^omervatjon  of  Erie  County  Amphibians  andReptjles^ 

Habitat  loss,  alteration,  and  fragmentation  are  suspected  to  be  the  greatest  threats  to  global 
amphibian  and  reptile  populations  (Mitchell  and  Klemens,  2000;  Semlitsch,  2003;  Gallant  et  al. 
2007).  As  urban  and  suburban  development  continues  in  Erie  County,  amphibian  and  reptile  habitat 
will  continue  to  decrease.  The  county  contains  a  variety  of  protected  habitats  (two  state  parks,  16 
state  game  lands,  one  county  park,  and  numerous  municipal  parks),  but  most  are  small  and  scat¬ 
tered,  and  as  such  will  become  increasingly  insular.  We  have  witnessed  habitat  alteration  at  many 
sites  that  may  have  negatively  affected  species  of  amphibians  and  reptiles  (Gray,  2006;  2007a  and 
b).  Conservation  of  Erie  County’s  amphibian  and  reptile  populations  will  require  educating  the 
public  about  the  importance  of  biodiversity,  the  encouragement  of  responsible  land  use  practices, 
and  additional  land  protection,  including  acquisition  and  conservation  easements.
