Females were larger than males in both snout-vent length (SVL) and pelvic width. The smallest sexually reproductive female was 80 mm SVL, whereas the smallest mature male was 60 mm. Female body size also correlated with clutch size (mean: 44.2, range: 19-74) and volume, suggesting the female-biased size dimorphism may be the product of fecundity selection. Males and females have slightly asynchronous reproductive cycles but breed during spring—-summer. but their diet is dominated both numerically and volumetrically by orthopterans, arthropods, coleopterans.

Chamaeleo dilepis feeds on a range of followed by Chamaeleo dilepis; sexual dimorphism; reproduction; diet; flap-necked chameleon ecology. Chameleons have evolved a unique set of traits that allow them to occupy a highly specialized niche. Typical chameleons have telescopic eyes, fusion of some digits, a prehensile tail, and a “ballistic” tongue that can exceed the length of their body, and they are capable of rapid color change (Tilbury, 2010). These features allow chameleons to hunt with stealth and may enable them to be less conspicuous to predators during prey capture. While the unique form and function of chameleons has attracted considerable atten- tion, we still have only a cursory grasp of their ecology and life history, although consider- © The President and Fellows of Harvard College 2012. i) able work has been done on reproduction and embryonic development in Chamaeleo calyp- tratus (e.g., Andrews, 2005, 2007, 2008), and we know the female reproductive cycle for Chamaeleo chamaeleon (Cuadrado and Lo- man, 1999). We also know the foraging mode of two species from different genera. Brady- podion pumilum has been classified as a “cruise” forager because it spends a high enough proportion of its time moving (21%) to qualify as an active forager, but it makes very few moves per minute (Butler, 2005). Similarly, an invasive population of Jackson’s chameleon (Chamaeleo jacksoni xanthopholis) in Hawaii spends 19.7% of its activity time in movement, with few moves per minute (¥ = 0.24; Hagey et al., 2010). These results are surprising given the highly specialized mor- phological features consistent with ambush foraging and suggest that chameleons employ a foraging mode quite distinct from those of most other lizards. In terms of sexual dimorphism, the males of many species have horns or protrusions that function as either armaments or ornaments, and males can be larger than females (Necas, 2001; Karsten ef al., 2009). In other species, including most of the dwarf chameleons (Bradypodion), females are larger than males, most likely as a result of fecundity selection (Stuart-Fox, 2009). Here, we describe the ecology of the flap- necked chameleon, Chamaeleo dilepis, with particular reference to sexual dimorphism, reproduction, and diet using specimens from the Ditsong National Museum of Natural History (formerly the Transvaal Museum) in South Africa. Chamaeleo dilepis is a large chameleon native to savannah woodland and sometimes coastal forest in sub-Saharan Africa (FitzSimons, 1943; Brain, 1961; Pie- naar, 1978; Branch, 1998; Tolley and Burger, 2007). This species is typically green or brown and usually possesses a pale stripe on the lower flanks and one to three pale patches higher on the flanks (Fig. 1; Tilbury, BREVIORA No. 532 2010). Interestingly, in the dry season in Kenya males tend to be brown and use defoliated vegetation, whereas females are mostly green and occupy leafy foliage. This difference falls away in the wet season when most individuals are green and occupy leafy vegetation (Hebrard and Madsen, 1984). Females are reported to be larger than males, although this has never been quantified (Brain, 1961; Necas, 2001; Tilbury, 2010). Chamaeleo dilepis in the wild lay their eggs in late summer in a tunnel 150-300 mm deep, excavated in damp soil. The eggs can take up to 377 days to hatch depending on environ- mental conditions (Brain, 1961; Wager, 1983; Branch, 1998). After egg laying, females are emaciated and generally vulnerable to a wide variety of predators that include various snakes, mongooses, raptors, hornbills, and monkeys (Pienaar, 1978; Branch, 1998; Van Wyk and Els, 2004; Cunningham and Adank, 2005; Tilbury, 2010). Chamaeleo dilepis has a broad distribution, and while a number of subspecies are recognized, their systematic and taxonomic status is uncertain (see Tilbury [2010] for a detailed discussion of their taxonomy). We examined only material from the southern African subregion (south and east of Kunene River separating Namibia from Angola and including southern Mozam- bique; see Appendix 1) and provide the first quantitative assessment of diet, reproduction and morphology. MATERIALS AND METHODS Dimorphism To quantify sexual size dimorphism, we measured morphological traits from a subset of mature individuals (80 of the 251 speci- mens; see below for maturity criteria). Snout- vent length (SVL) was measured from the tip of the snout to the anterior edge of the cloaca 2012 ECOLOGY OF CHAMAELEO DILEPSIS 3 Figure 1. and a row of raised triangular tubercles extending from the tip of the snout down the ventral midline. The southern African forms look identical. Photo by M. J. Whiting. and tail length from the posterior edge of the cloaca to the tip of the tail. Head height was measured as the distance between the center of the parietal bone to the bottom of the articular. Head width was measured at the widest point of the head. Head length was measured from the tip of the snout to the back of the skull. The femur, tibia, humerus, and ulna were measured from the proximal to distal ends of the bones. Pelvic width was measured between the outer edges of the iliac bones. SVL and tail length were measured with a ruler to the nearest | mm, whereas digital calipers were used to measure the remaining morphological measurements to A typical Chamaeleo dilepis from Chuka, Kenya, with characteristic pale flank patches, occipital flaps, the nearest 0.01 mm. Before testing for differences in sexual dimorphism, we re- moved the effect of size by regressing each morphological measurement on SVL. We made pairwise plots to determine if there were any outliers and removed one specimen from the analysis because it was an outlier in the majority of the plots. A principal components analysis was then performed on SVL and the residuals resulting from the regression of each of the measured characters on SVL. We retained the first three principal components because they explained the ma- jority of the variation. We then used a multivariate analysis of variance (MANOVA) 4 BREVIORA on the first three principal components to determine whether trait variation among individuals of C. dilepis could be explained significantly by sex. Reproduction We made a mid-ventral incision to expose the gonads and score sexual maturity. Males were recorded as sexually mature if they contained enlarged testes and convoluted epididymides. We measured the right testis for length and width to the nearest 0.01 mm using digital calipers. Testis volume (right testis) was then determined using the formula for-a prolate spheroid (Vitt et al, 1993; Vitt and Zani, 2005): volume =4/3z(length/2) « (width /2) We scored females as sexually mature if they contained oviductal eggs, enlarged vitellogenic follicles or a convoluted oviduct. For gravid females (sexually active), oviductal eggs were counted and the size (length and width) of each egg was measured to the nearest 0.01 mm using digital calipers. Ovi- ductal egg volume was then calculated using the formula for a prolate spheroid (as above). Diet We removed stomach contents and spread them on a Petri dish for identification to order. The length and width of all intact prey items were measured to the nearest 0.01 mm using digital calipers. Prey volume was cal- culated using the formula for a prolate spheroid (as above). We estimated niche breadth using the reciprocal of Simpson’s (1949) diversity measure, No. 532 where 7 = resource category, p = proportion of resource category 7, and n = total number of categories. Values vary from 1 (exclusive use of one prey type) to n (even use of all prey types). Prey categories were the arthro- pod orders of prey items found in the stomach contents. All data are reported as ¥ + 1 SE and differences were considered significant when alpha was < 0.05. RESULTS Dimorphism The first three principal components (PCs) explained 97% of the variation (Table 1), with PCI explaining 79.5% of the variation, PC2 14.5%, and PC3 3.2%. PC1 loads only for body size (as represented by SVL); PC2 correlates most strongly with tail length, and to a lesser extent by head length and ulna length; and PC3 correlates primarily with tibia length, femur length, humerus length, ulna length, head height, and head length. The sexes differ in position in the multi- variate space defined by these axes (MAN- OVA F375 a 3.899, P= 0.012), with the first principal component being highly significant (Fi 75 = 7.613, P = 0.007), the second component only tending toward significance (F, 75 = 3.300, P = 0.073), and the third being nonsignificant (F,75 = 0.783, P = 0.38). Females were significantly larger than males, with the largest female measuring 162 mm SVL, whereas the largest male was only 126 mm (Table 2). Reproduction The smallest sexually mature female was 80 mm SVL (Fig. 2). Clutch size (n = 25) averaged 44.2 + 14.7 (range, 19-74). Female SVL was significantly positively correlated with both clutch size (7? = 0.472, Fy24 = 2012 ECOLOGY OF CHAMAELEO DILEPSIS 5 TABLE 1.

Diet We identified 13 prey categories in the stomachs of 206 C. dilepsis (the remaining 45 were empty; Table 3, Fig. 4A, B). Although the majority of prey items consumed were arthropods, a snail and two reptiles (a skink and a gecko) were found in three individuals (Fig. 4A). Most of the arthropods consumed were insects (85.4%).

DISCUSSION Of the 14 morphological variables we measured in C. dilepis, only SVL and pelvic width differed significantly between the sexes. Females were significantly larger than males in both SVL and pelvic width. In squamate reptiles, the degree of sexual dimorphism depends on the relative strength of natural and sexual selection on both sexes (Fitch, 1981) and disentangling these effects can be difficult. Among 21 lineages of the viviparous dwarf chameleons (Bradypodion), females were significantly larger in 15 (71%) cases (Stuart-Fox, 2009). Chameleons also tend to have relatively large clutches (max- imum, 74 in this study) and as_ such, fecundity selection might favor larger fe- males relative to any selective pressures that may be acting on male body size. Further- more, female SVL was positively correlated with both clutch size and total clutch volume, suggesting that larger SVL and pelvic width in females is an adaptation to increased female fecundity. Male and female reproductive cycles did not appear to be highly synchronized. Females appear to be seasonal, commencing vitellogenesis in summer (November) and containing fully developed eggs throughout the warmer months of the year (November— May). Males have winter and summer peaks in testes volume and appear to commence 2012 ECOLOGY OF CHAMAELEO DILEPSIS 9 Number of prey items consumed (%) Volume of prey items consumed (%) on WY g F é 2 = E 3 £ o a e > = a 3 z ge & —- = eT: Figure 4.

Of the 25 gravid females we examined, the mean was 44, and the largest clutch was 74. These are high values for any lizard and suggest that chameleons are typical capital breeders that invest heavily in a single reproductive event (see Bonnet et al, 1998). However, in the similar sized but distantly related Trioceros [Chamaeleo| montium from Cameroon, clutch size 1s considerably smaller: 3-12 (mean, 6.5), and mean relative clutch mass was 40% (Herrmann and Herrmann, 2005). Andrews and Karsten (2010) provide an excellent review of the evolution of reproductive mode, developmental rate, and body size in chame- leons. In the context of their review, C. dilepis is a relatively large sized, derived chame- leon that develops comparatively slowly. Relationship between SVL (mm) and total prey volume (mm+) in Chamaeleo dilepsis. Furthermore, this species has embryonic diapause because the eggs overwinter under- ground. This reproductive strategy is thought to have evolved in habitats experiencing dry, seasonal climates, thereby increasing the likelihood that the eggs hatch during favor- able conditions the following season (An- drews and Karsten, 2010). The majority of prey consumed by C. dilepis, both volumetrically and numerically, were orthopterans, followed by coleopterans. Prey volume was a function of body size, with larger individuals consuming larger prey volumes. However, SVL and _ prey number were not significantly correlated, possibly because most individuals contained relatively few prey items. Gape size was correlated with both prey number and the largest prey item consumed. A relatively large number of individuals contained prey items in their stomach (82%), suggesting that C. dilepsis feed frequently. This agrees with 2012 the patterns reported by Huey ef al. (2001) that most diurnal lizards maintain a positive energy balance. Nine individuals were also found to contain a single millipede, a prey item usually avoided by many reptiles because of their toxicity (Wapstra and Swain, 1996). However, the presence of noxious millipedes has been found in the diet of two other African species (African tree agama, Acantho- cercus a. atricollis, Reaney and Whiting, 2002; Wahlberg’s velvet gecko, Homopholis wahl- bergii, Whiting et al., 2007). Together with numerous anecdotal reports of miullipede consumption (Branch, 1998), these studies suggest that they are at least occasional prey items of African lizards either because they are less toxic than their North American counterparts or because African lizards are better adapted to deal with their toxicity. In addition to insects, six chameleons had eaten spiders, one had eaten a mollusk, and two had eaten lizards. These constitute a very small proportion (< 4%) of C. dilepis specimens that contained food items. Only a few instances of vertebrate predation by C. dilepis have been reported in the literature, including two geckos and a case of canni- balism (Tilbury, 2010). Therefore, although C. dilepis may on occasion take noninsect prey, their diet is dominated by a relatively narrow range of insect prey. Our results largely confirm previous anecdotal reports. Chamaeleo dilepis 1s reported to feed mainly on grasshoppers and beetles (Branch, 1998; Tilbury, 2010), but also to include occasional butterflies, dragonflies, winged termites, myriapods, various flying insects, and inver- tebrates such as snails and spiders (Fitz- Simons, 1943; Brain, 1961; Pienaar, 1978). The similarly sized Chamaeleo namaquensis, which is terrestrial, has a similar diet, ex- ECOLOGY OF CHAMAELEO DILEPSIS I] cept that tenebrionid beetles are their most commonly consumed (and probably encoun- tered) prey (Burrage, 1973). Three species of rainforest chameleons (Chamaeleo) from Cameroon were relatively opportunistic, feeding on mainly coleopterans, heteropter- ans, hymenopterans, dipterans, and spiders (Hofer et al, 2003). Similarly, the common chameleon (Chamaeleo chamaeleon) from the Iberian Peninsula feeds on Diptera, Hyme- noptera, Orthoptera, and Heteroptera with little seasonal variation and no differences between males and females (Pleguezuelos et al., 1999). In summary, our study provides the first quantitative baseline ecological data for C. dilepis, one of few species of chameleons to occur in a savanna biome. Chamaeleo dilepis is an insectivore that consumes mostly orthopterans and coleopterans; they follow a typical spring-summer reproductive cycle, and females are larger than males and invest heavily in egg production. Chameleons have long been underrepresented in ecological studies, but given the substantial investment of females in egg production, their unique morphology, and their wide distribution across habitats of varying rainfall and tem- perature, they promise to be an interesting model group for future studies.
