(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 The addition of Anolis cristatellus to species lists of Dominica has made many guides and species lists outdated.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. -
Anolis Aeneus (Bronze Anole)
UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour Anolis aeneus (Bronze Anole) Family: Polychrotidae (Anoles) Order: Squamata (Lizards and Snakes) Class: Reptilia (Reptiles) Fig. 1. Bronze anole, Anolis aeneus. [http://www.trinidad-tobagoherps.org/Anolisaeneus.htm, downloaded 20 October 2012] TRAITS. Anolis aeneus can be distinguished by the blue-green ring around its eyes (Murphy 2011). The species is a medium sized anole, the length of males from the tip of the nose to the anus is 77 mm and females 55 mm (John et al. 2012). They have many lamellae (flaps) on their subdigital toepads. The dewlap (throat fan) extends from underneath their necks and has a pale gray, green or white colour, yellow or orange spots may also be present at the front edge of the dewlap (John et al. 2012). Colour: The dorsal side of the males may be grey, greyish brown, brown or a dull green, a bronze sheen is at times present, light or dark spots may be present in a crosswise pattern. The underside has a dull grey colour. The females may be grey or brown the mid-dorsal region can include a dark single stripe or a transverse stripe, juveniles are dark grey or brown (John et al. 2012). ECOLOGY. This species is endemic to Grenada and has been introduced to Trinidad and Tobago (Wikipedia 2012). It is an arboreal species and can therefore be found mostly on the trunk and branches of shaded trees, it is also populated in urban areas and can be observed on walls, railings and fences (Murphy 2011) it feeds on live insects and invertebrates such as crickets, roaches and spiders. -

We also report phenotypic variation in the color pattern and scutellation on throat and pelvic regions of males from both eastern and western populations, which is described below. Furthermore, based on these new data, we confirm that the species is not fitting in its current IUCN category, and in consequence propose updating its conservation status.

A Novel Colour Morph of Sphaerodactylus Sabanus Cochran 1938 from Sint Eustatius
Herpetology Notes, volume 13: 1035-1039 (2020) (published online on 14 December 2020) A novel colour morph of Sphaerodactylus sabanus Cochran 1938 from Sint Eustatius Michael L. Yuan1,2,3,*, Jeffrey H. Frederick2,4, and Rayna C. Bell3,5 Abstract. Reptiles often display substantial intraspecific variation in dorsal colouration and pattern. Such variation is often, but not always, genetically or geographically structured. In particular, the Sphaerodactylus geckos of the Caribbean display considerable intraspecific variation in dorsal patterning. Here, we describe a previously unreported colour and pattern morph of the Saint Kitts Bank Geckolet, Sphaerodactylus sabanus, restricted to the island of Sint Eustatius. We surveyed dorsal patterns throughout the range of S. sabanus using both field surveys and museum collections. For field samples, we sequenced the mitochondrial 12S gene to confirm the identity of each specimen and to examine genetic structuring of pattern morphs. Additionally, we compared the relative ratios of each morph across the four main islands within its range: Saba, Sint Eustatius, Saint Kitts, and Nevis. Although relative abundances of each dorsal pattern varied across islands, we found no evidence of either geographic or genetic structure related to dorsal pattern. Thus, Sphaerodactylus sabanus may provide a compelling system to study alternative drivers of intraspecific colour and pattern variation. Keywords. Caribbean, Lesser Antilles, Reptile, Gecko, Sphaerodactylidae, Intraspecific Variation Introduction not correspond with mitochondrial genetic structure or geography (Thorpe et al., 2008; Surget-Groba and Native to Central America and the Caribbean, several Thorpe, 2012; but see Daza et al., 2019). species of Sphaerodactylus exhibit dramatic variation in Sphaerodactylus sabanus Cochran 1938 is native dorsal colour and patterns throughout their ranges (e.g., to the islands of the Saint Kitts Bank (Sint Eustatius, King, 1962; Thomas, 1964; Thorpe et al., 2008; Daza et Saint Kitts, and Nevis) and Saba. -

Snakes: Cultural Beliefs and Practices Related to Snakebites in a Brazilian Rural Settlement Dídac S Fita1, Eraldo M Costa Neto2*, Alexandre Schiavetti3
Fita et al. Journal of Ethnobiology and Ethnomedicine 2010, 6:13 http://www.ethnobiomed.com/content/6/1/13 JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE RESEARCH Open Access ’Offensive’ snakes: cultural beliefs and practices related to snakebites in a Brazilian rural settlement Dídac S Fita1, Eraldo M Costa Neto2*, Alexandre Schiavetti3 Abstract This paper records the meaning of the term ‘offense’ and the folk knowledge related to local beliefs and practices of folk medicine that prevent and treat snake bites, as well as the implications for the conservation of snakes in the county of Pedra Branca, Bahia State, Brazil. The data was recorded from September to November 2006 by means of open-ended interviews performed with 74 individuals of both genders, whose ages ranged from 4 to 89 years old. The results show that the local terms biting, stinging and pricking are synonymous and used as equivalent to offending. All these terms mean to attack. A total of 23 types of ‘snakes’ were recorded, based on their local names. Four of them are Viperidae, which were considered the most dangerous to humans, besides causing more aversion and fear in the population. In general, local people have strong negative behavior towards snakes, killing them whenever possible. Until the antivenom was present and available, the locals used only charms, prayers and homemade remedies to treat or protect themselves and others from snake bites. Nowadays, people do not pay attention to these things because, basically, the antivenom is now easily obtained at regional hospitals. It is under- stood that the ethnozoological knowledge, customs and popular practices of the Pedra Branca inhabitants result in a valuable cultural resource which should be considered in every discussion regarding public health, sanitation and practices of traditional medicine, as well as in faunistic studies and conservation strategies for local biological diversity. -
