Ecology of a snake assemblage in the Atlantic Forest of southeastern Brazil
Provedor de dados: 84
Autores: Hartmann,Paulo A.; Hartmann,Marília T.; Martins,Marcio.
The main objective of this study was to examine the natural history and the ecology of the species that constitute a snake assemblage in the Atlantic Rainforest, at Núcleo Picinguaba, Parque Estadual da Serra do Mar, located on the northern coast of the state of São Paulo, southeastern Brazil. The main aspects studied were: richness, relative abundance, daily and seasonal activity, and substrate use. We also provide additional information on natural history of the snakes. A total of 282 snakes, distributed over 24 species, belonging to 16 genera and four families, has been found within the area of the Núcleo Picinguaba. Species sampled more frequently were Bothrops jararaca and B. jararacussu. The methods that yielded the best results were time constrained...

Natural History of Pseudoboine Snakes
Provedor de dados: 84
Autores: Gaiarsa,Marília P.; Alencar,Laura R.V. de; Martins,Marcio.
Even though natural history information is crucial for answering key ecological, evolutionary, and conservation questions, basic studies are still lacking for Neotropical snakes. This study aims at contributing to the knowledge of the Neotropical tribe Pseudoboini, based on literature data, analysis of museum specimens and unpublished data. The tribe is mainly composed of moderate-sized snakes, although small and large-sized snakes also occur in the clade. Mean fecundity ranged from two (Rodriguesophis iglesiasi) to 29 eggs (Clelia plumbea) and the species are predominantly terrestrial and nocturnal. Most species are diet specialists and lizards are the most commonly consumed prey (found in the diet of 29 species), followed by small mammals (consumed by 20...

A new ‘horned’ Stenocercus from the highlands of southeastern Brazil, and redescription of Stenocercus tricristatus (Reptilia: Tropiduridae)
Provedor de dados: 103
Autores: Ávila-Pires,Teresa C. S.; Nogueira,Cristiano de C.; Martins,Marcio.
ABSTRACT A new species of the lizard genus Stenocercus Duméril &amp; Bibron, 1837 is described based on six specimens from Serra da Canastra, Minas Gerais, southeastern Brazil. Similar to S. tricristatus (Duméril, 1851), S. dumerilii (Steindachner, 1867), S. quinarius Nogueira &amp; Rodrigues, 2006, and S. squarrosus Nogueira &amp; Rodrigues, 2006, the new species has a pyramidal head and an enlarged, dorsally projected post-supraciliary scale, like a small horn. It is most similar to S. tricristatus, from which it differs in having a more elongated head in ventral view; a larger number of scales around midbody; a distinctly enlarged, smooth preauricular scale; and probably a larger body size. Moreover, the new species has distinctly keeled scales, with...

Eficiência de armadilhas de queda (pitfall traps) em amostragens de anfíbios e répteis no Brasil
Provedor de dados: 104
Autores: Cechin,Sônia Zanini; Martins,Marcio.
The effectiveness of pitfall traps associated with drift fences to capture amphibians and reptiles in three field studies, in Rio Grande do Sul (extreme southern Brazil), São Paulo (São Paulo, southeastern Brazil), and Amazonas (Amazonas, northern Brazil) is described. At Santa Maria, a total of 2040 amphibians and reptiles were caught in 30 pitfalls (200 L, with drift fence) during 18 months of study (capture efficiencies of 3.78 amphibians and reptiles/pitfall/month and 0.14 snake/pitfall/month). At Itirapina, São Paulo, 1262 amphibians and reptiles were obtained in 72 pitfalls (100 L, with drift fence) during six months (capture efficiencies of 11,9 amphibians and reptiles/pitfall/month and 0,38 snake/pitfall/month). At Rio Pitinga, Amazonas, over 600...

Composition and natural history of a Cerrado snake assemblage at Itirapina, São Paulo state, southeastern Brazil
Provedor de dados: 49
Autores: Sawaya,Ricardo Jannini; Marques,Otavio Augusto Vuolo; Martins,Marcio.
Neotropical snake assemblages present high species richness and complex structures. The Cerrado is the second largest biome in Brazil, and was included among the 25 World's biodiversity hotspots. In southeastern Brazil, the remnant Cerrado areas have suffered intense destruction, and presently less than 2% of Cerrado natural vegetation remain in São Paulo state. Virtually no detailed study on Cerrado snakes was carried out in this region. The Itirapina region has one of the last well preserved remnants of open cerrado in São Paulo state. Our purpose in this work was the study of natural history and composition of the Cerrado snakes of Itirapina region. We performed an extensive field sampling combining six sampling methods in Estação Ecológica de Itirapina...

Amphibians of an open cerrado fragment in southeastern Brazil
Provedor de dados: 49
Autores: Brasileiro,Cínthia Aguirre; Sawaya,Ricardo J.; Kiefer,Mara C.; Martins,Marcio.
The Cerrado encompasses ca. 2 million km² in Brazil. Most Cerrado areas have been greatly disturbed in the past decades. Only 20% of this biome remain undisturbed, and only 1.2% is protected. Knowledge on the biology and diversity of Cerrado amphibian assemblages is still incipient. Here we present natural history information (habitat use and reproductive activity) of 28 species of frogs from the Estação Ecológica de Itirapina (EEI), and compare the composition of this assemblage with those of other Cerrado areas, other open areas, and a few forest areas throughout Brazil. We demonstrate that the Itirapina assemblage is more similar to those of other open areas than to those of forests, even when the latter are geographically closer. Six species occurred...

Anurans from preserved and disturbed areas of Atlantic Forest in the region of Etá Farm, municipality of Sete Barras, state of São Paulo, Brazil
Provedor de dados: 49
Autores: Fiorillo,Bruno Ferreto; Faria,Carolina Sconfienza; Silva,Bruno Rocha; Martins,Marcio.
Abstract: We provide information on the diversity and natural history of anurans from preserved and disturbed habitats in the region of Etá Farm, municipality of Sete Barras, state of São Paulo, Brazil. The region is covered by rainforest and plantations of banana and peach palm. From April, 2013 to March, 2014 we sampled amphibians mainly with pitfall traps with drift fences and visual and auditory surveys. A total of 9813 individuals of 36 species of anurans from nine families were recorded in this study. A larger number of species was found in forests (29 species), followed by peach palm plantations (21 species), and banana plantations (17 species). The areas of peach palm plantation and forests showed the greatest similarity in species composition. The...

Impactos potenciais das mudanças propostas no Código Florestal Brasileiro sobre os répteis brasileiros
Provedor de dados: 49
Autores: Marques,Otavio Augusto Vuolo; Nogueira,Cristiano; Martins,Marcio; Sawaya,Ricardo Jannini.
Avaliamos os impactos potenciais sobre a fauna brasileira de répteis (721 espécies descritas até o momento), caso sejam adotadas mudanças propostas por um substitutivo do atual Código Florestal Brasileiro. A possibilidade de compensação ambiental (obrigação legal no caso de degradação de habitats naturais) em bacias ou microbacias distintas daquelas degradadas seria uma das modificações do código vigente que prejudicaria a manutenção da diversidade de répteis. Alguns gêneros de répteis são compostos por espécies que raramente co-ocorrem em uma mesma área. Assim, ações de conservação em escalas reduzidas, em unidades naturais como microbacias, seriam mais adequadas para representar a variação da composição de espécies entre áreas. O substitutivo prevê a...
