“…Recent systematic surveys on different environments within the island have failed to record the occurrence of this gecko outside anthropic and peri-antropic habitats Winck, 2012). However, more recent surveys carried out by our research team have recorded 17 individuals (and two eggs) of H. mabouia in natural environments of Praia do Sul, in the RBEPS, thus evidencing that this species has become an invasive exotic in that area (Telles et al, 2015). Considering the two previous surveys in the island that did not find this lizard in natural environments, we suggest that the invasion of the restinga habitat in Praia do Sul by this gecko may be quite recent.…”

The Herpetofauna from Ilha Grande (Angra dos Reis, Rio de Janeiro, Brazil): updating species composition, richness, distribution and endemisms

et al. 2018

Ilha Grande is a large continental island (total area of 19,300 ha) situated at the southern coast of the state of Rio de Janeiro, in southeast Brazil, within the Atlantic Forest Biome. Here we provide an update to the previous knowledge of the fauna of amphibians and reptiles occurring in Ilha Grande, based on primary data from our own fieldwork and on secondary data (from institutional collections and from the literature). We report the occurrence at Ilha Grande of a total of 74 species, being 34 amphibians (all of them anurans) and 40 reptiles (27 snakes, 11 lizards, one amphisbaenian and one crocodylian). Our survey added 14 species to the herpetofaunal list of Ilha Grande (three of amphibians and eleven of reptiles) and removed one species (the amphibian Cycloramphus fuliginosus) from the previous list. The data indicated that Ilha Grande houses a considerable portion of the Atlantic Forest amphibian and reptile diversity (ca. 6% and 19%, respectively, of the species occurring in this biome) together with high occurrence of species endemic to this biome plus a few amphibian species endemic to this island. Ilha Grande is thus an important reservoir of both biodiversity and endemism of amphibians and reptiles of the Atlantic Forest of Brazil, which highlights the importance of the conservation of the island and of its different habitats along the insular landscape.

“…Hemidactylus mabouia, a non-indigenous lizard, was recorded in a forest fragment next to a banana plantation at the borders of the MONAST. This gekko is native to Africa, and has invaded a number of different natural environments in Brazil (Rocha et al 2011, Telles et al 2015, Oliveira et al 2016, including many ombrophilous forest remnants (Rocha et al 2011;Telles et al 2015). The occurrence of H. mabouia in the MONAST is consistent with the dispersal of the species in other regions, where it is associated with open areas impacted by human activities (Rocha et al 2011;Oliveira et al 2016).…”

Reptiles of the Serra das Torres Natural Monument: using the Rapid Assessment method to fill a knowledge gap in the Atlantic Forest of southeastern Brazil

et al. 2020

Data on the composition of local reptile assemblages in several Brazilian ecosystems can still be considered relatively restricted in scope in most cases. In this study, we conducted surveys in the Serra das Torres Natural Monument, located in the municipalities of Atílio Vivacqua, Muqui, and Mimoso do Sul, using the Rapid Assessments method (RAP) during 30 days in the rainy season of 2018. We sampled actively for approximately 1320 hours with a 6-10 person crew, supplemented by 720 hours of passive sampling (30 bucket-days) using pitfall traps with drift fences. We recorded 34 reptile species during our sampling method (2 amphisbaenid, 11 lizards, and 21 snakes) and an occasional encounter, after the end of sampling, that added a chelonian species to the list, Hydromedusa maximiliani, totaling 35 reptile species. The Dipsadidae was the family with the greatest snake species richness and, the Gymnophtalmidae had the greatest lizard species richness. The species richness recorded in the Serra das Torres Natural Monument (Ntotal = 35) represents ca. 27% of all reptile species found in the state of Espírito Santo (N = 130). The most abundant lizard species was Leposoma scincoides followed by Ecpleopus gaudichaudii and, the most abundant snake species was Bothrops jararaca being markedly higher than that recorded in similar studies. Twenty-seven percent of the reptile species recorded in our study are endemic to the Atlantic Forest and 30% (N = 10) have been recorded less than five times previously in the Brazilian state of Espírito Santo. Our study reinforces the need for the conservation of the Serra das Torres Natural Monument because of its importance as a reservoir of a considerable portion of the reptile biodiversity of Espírito Santo state, and of the Atlantic Forest biome as a whole.

“…We also recorded the non-indigenous gekkonid Hemidactylus mabouia, a species of African origin, as invasive in different restinga habitats (e.g. Hatano et al, 2001;Rocha and Bergallo, 2011;Telles et al, 2015;Oliveira et al, 2016;Winck et al, 2016). In one study we analyzed the lizard species in 16 restinga habitats encompassing three Brazilian states (Rio de Janeiro, Espírito Santo and Bahia) and along more than 1500 km of Brazilian coast, registering this invasive lizard in some of them (Rocha et al, 2014).…”

A summary of reptile and anuran amphibian species from Brazilian sandy coastal plains: 31 years of sampling efforts of the “Laboratório de Ecologia de Vertebrados, Universidade do Estado do Rio de Janeiro”

Although currently there is already a set of studies regarding ecological aspects of some particular reptile and amphibian species living in Brazilian sandy coastal plains (including the so-called “restinga” and “campo nativo” habitats), there is comparatively few information on the species composition usually associated to these environments. During 31 years (1988-2019) of herpetological studies carried out in sandy coastal plains environments by our research team of the Laboratory of Vertebrate Ecology (Department of Ecology, Universidade do Estado do Rio de Janeiro, in Rio de Janeiro Brazil) we have surveyed reptile and amphibian communities and performed different studies with similar methods in 70 sites from 10 different states along the Brazilian coast. Our surveys resulted in records of 87 species of reptile (five turtles, two crocodylians, six amphisbaenians, 36 lizards and 39 snakes) from 24 families, and 77 species of anuran amphibians from nine families. We have studied multiple natural history topics for anurans and reptiles which resulted in the publication of some specific ecological studies, especially regarding some species, encompassing population and community ecology, foraging and feeding habits, species activity, thermoregulation, reproduction, use of microhabitats, and parasitism by ecto and endoparasites. Our results along these three decades have also contributed for the description of four new lizard species (Ameivula nativo, Glaucomastix littoralis, G. abaetensis and G. itabaianensis). Our studies constitute an important contribution to the knowledge of the ecology of anuran amphibians and reptiles in these ecosystems, as well as to the conservation of sandy coastal plains environment. The checklist presented in this study, based on our records of sandy coastal plains herpetofauna, provides for many localities along the Brazilian coast, the needed knowledge on species occurrence, including the presence of endemic and/or endangered species, which can be of value for many conservation actions.
