(2007) a Photographic Field Guide to the Reptiles and Amphibians Of
A Photographic Field Guide to the Reptiles and Amphibians of Dominica, West Indies Kristen Alexander Texas A&M University Dominica Study Abroad 2007 Dr. James Woolley Dr. Robert Wharton Abstract: A photographic reference is provided to the 21 reptiles and 4 amphibians reported from the island of Dominica. Descriptions and distribution data are provided for each species observed during this study. For those species that were not captured, a brief description compiled from various sources is included. Introduction: The island of Dominica is located in the Lesser Antilles and is one of the largest Eastern Caribbean islands at 45 km long and 16 km at its widest point (Malhotra and Thorpe, 1999). It is very mountainous which results in extremely varied distribution of habitats on the island ranging from elfin forest in the highest elevations, to rainforest in the mountains, to dry forest near the coast. The greatest density of reptiles is known to occur in these dry coastal areas (Evans and James, 1997). Dominica is home to 4 amphibian species and 21 (previously 20) reptile species. Five of these are endemic to the Lesser Antilles and 4 are endemic to the island of Dominica itself (Evans and James, 1997). The addition of Anolis cristatellus to species lists of Dominica has made many guides and species lists outdated. Evans and James (1997) provides a brief description of many of the species and their habitats, but this booklet is inadequate for easy, accurate identification. Previous student projects have documented the reptiles and amphibians of Dominica (Quick, 2001), but there is no good source for students to refer to for identification of these species. -

Dorsal and lateral coloration is very dark brown to slate black and usually patternless (one individual, MCZ 6141, has a trace of a pattern with faded spots on the posterior third of the dor- sum and some balck blotches on the side of the neck). Brown color often is more distinct on the heads of males. The venter is very dark blue-gray. -
Xenosaurus Tzacualtipantecus. the Zacualtipán Knob-Scaled Lizard Is Endemic to the Sierra Madre Oriental of Eastern Mexico
Xenosaurus tzacualtipantecus. The Zacualtipán knob-scaled lizard is endemic to the Sierra Madre Oriental of eastern Mexico. This medium-large lizard (female holotype measures 188 mm in total length) is known only from the vicinity of the type locality in eastern Hidalgo, at an elevation of 1,900 m in pine-oak forest, and a nearby locality at 2,000 m in northern Veracruz (Woolrich- Piña and Smith 2012). Xenosaurus tzacualtipantecus is thought to belong to the northern clade of the genus, which also contains X. newmanorum and X. platyceps (Bhullar 2011). As with its congeners, X. tzacualtipantecus is an inhabitant of crevices in limestone rocks. This species consumes beetles and lepidopteran larvae and gives birth to living young. The habitat of this lizard in the vicinity of the type locality is being deforested, and people in nearby towns have created an open garbage dump in this area. We determined its EVS as 17, in the middle of the high vulnerability category (see text for explanation), and its status by the IUCN and SEMAR- NAT presently are undetermined. This newly described endemic species is one of nine known species in the monogeneric family Xenosauridae, which is endemic to northern Mesoamerica (Mexico from Tamaulipas to Chiapas and into the montane portions of Alta Verapaz, Guatemala). All but one of these nine species is endemic to Mexico.

Fialho4 Lizards and frogs are eaten by a wide range of wetlands, being found mainly in lakes, wetlands, predators and are a food source for many bird species flooded areas, rivers, dams, mangroves, swamps, in neotropical forests (Poulin et al., 2001). However, and the shallow waters of salt lakes. It is a species predation events are poorly observed in nature and of diurnal feeding habits, but its activity peak occurs hardly documented (e.g., Malkmus, 2000; Aguiar and either at dawn or dusk. This characteristic changes Di-Bernardo, 2004; Silva et al., 2021). Such records in coastal environments, where its feeding habit is are certainly very rare for the teiid lizard Ameiva linked to the tides (McCrimmon et al., 2020). Its diet ameiva (Linnaeus, 1758) (Maffei et al., 2007). is varied and may include amphibians, snakes, insects, Found in most parts of Brazil, A. ameiva is commonly fish, aquatic larvae, mollusks, small crustaceans, small known as Amazon Racerunner or Giant Ameiva, and birds, small mammals, and lizards (Martínez-Vilalta, it has one of the widest geographical distributions 1992; Miranda and Collazo, 1997; Figueroa and among neotropical lizards. It occurs in open areas all Corales Stappung, 2003; Kushlan and Hancock 2005). over South America, the Galapagos Islands (Vanzolini We here report a predation event on the Ameiva ameiva et al., 1980), Panama, and several Caribbean islands by Ardea alba in the southwestern Brazilian Amazon. -

Gerencia de Investigación y Desarrollo, Jardín Botánico de Caracas, Universidad Central de Venezuela, Caracas, Venezuela ([email protected]). ABSTRACT Food habits among sexes of Ameiva ameiva were evaluated by the frequency of occurrence, trophic dominance, and diet similarity methods during periods of rain and drought in a tropophic forest in La Llanada Vieja, Sucre State, Venezuela. 431 prey items were identified in 20 stomachs analyzed. Diet for both periods showed a high frequency for Coleoptera, plant material, Isoptera, Nematoda, Araneae, and reptilian rests. Males and females showed differences in diet during the climatic periods analyzed. Females showed higher stomach volumes values than males. Results suggest the species is mainly insectivorous. RESUMEN Se evaluaron los hábitos alimentarios de Ameiva ameiva, mediante el método de frecuencia de aparición, dominancia trófica y similitud de la dieta entre sexos, abarcando los periodos de lluvia y sequía. La captura se realizó en un bosque tropófilo de los alrededores de la Llanada Vieja, estado Sucre, Venezuela. -

The Striped Whipsnake (Masticophis taeniatus) occurs across 11 western U.S. states and into Mexico but has experienced population declines in parts of its range, particularly in the state of Washington. We analyzed nuclear and mitochondrial DNA extracted from 192 shed skins, 63 muscle tissue samples, and one mouth swab to assess local genetic diversity and differentiation within and between the last known whipsnake populations in Washington. We then placed that information in a regional context to better understand levels of differentiation and diversity among whipsnake populations in the northwestern portion of the range of the species. Microsatellite data analyses indicated that there was comparable genetic diversity between the two extant Washington populations, but gene flow may be somewhat limited. We found moderate to high levels of genetic differentiation among states across all markers, including five microsatellites, two nuclear genes, and two mitochondrial genes. -
Ameiva Ameiva (Zandolie Or Jungle Runner)
UWI The Online Guide to the Animals of Trinidad and Tobago Ecology Ameiva ameiva (Zandolie or Jungle Runner) Family: Teiidae (Tegus and Whiptails) Order: Squamata (Lizards and Snakes) Class: Reptilia (Reptiles) Fig. 1. Zandolie, Ameiva ameiva. [https://c2.staticflickr.com/4/3804/13311081294_c5a2cfcfc8_b.jpg, downloaded 29 March 2015] TRAITS. Ameiva ameiva lizards are large bodied, streamlined in shape, their heads are pointed and their tongues are slightly forked. Their legs are short and their hind legs are very muscular (Fig. 1). These lizards display sexual dimorphism. The female body length is approximately 49cm and the male 56 cm (ttfnc.org, 2006). The males are larger than the females in size, their backs are dull green and their flanks are colourful, whereas the females are quite similar but they have much brighter green backs (Kenny, 2008). The males also have relatively larger heads than the females (Colli and Vitt, 1994). Juveniles have relatively large heads for their body size. Ameiva ameiva is also called the jungle runner or giant ameiva (Myfwc.com, 2015). DISTRIBUTION. According to Animal Diversity Web (2014), Ameiva ameiva is found in Central and South America and in some parts of the Caribbean. Countries include; Brazil, Panama, Trinidad and Tobago, Suriname, Colombia and many others. UWI The Online Guide to the Animals of Trinidad and Tobago Ecology HABITAT AND ACTIVITY. They are diurnal, found in open tropical forests, woodlands and agricultural land (Anapsid.org, 1995), in open, sunny, grassy areas. Biazquez (1996) says that both adults and juveniles liked sunny areas and they spend most of their time foraging and basking. -
