Dendrophryniscus brevipollicatus Jiménez de la Espada is a Neotropical bufonid endemic to small range of the Brazilian Coastal Atlantic Forest, with reduced body size for family and bromeligenous habit. We reviewed taxonomic status populations D. from states Rio Janeiro São Paulo, including some continental islands, based on external morphology. tested our morphological species by DNA-barcoding approach sequences 16S RNA ribosomal gene fragment. analysis included other recognized was...

Morphological similarity associated to restricted distributions and low dispersal abilities make the direct developing “Terrarana” frogs of genus Euparkerella a good model for examining diversification processes. We here infer phylogenetic relationships within Euparkerella, using DNA sequence data from one mitochondrial four nuclear genes coupled with traditional Bayesian reconstruction approaches more recent coalescent methods species tree inference. also used clustering analysis...

Species inventories are useful tools to improve conservation strategies, especially in highly threatened biomes such as the Brazilian Atlantic Forest. Here we present a species list of amphibians and reptiles for Reserva Ecológica de Guapiaçu (REGUA), forest reserve located central portion Rio Janeiro state, Brazil. The results from an extensive sampling effort that lasted ten years. A total 73 amphibian (of which endemic state) 37 reptile was recorded area. Five presently categorized by...

Haddadus binotatus is an endemic anuran of the Brazilian Atlantic Forest and currently, there no information about diet this species. We analyzed two populations in states southeast Brazil. Samplings were carried out 2004 state Rio de Janeiro 2009 2010 Espírito Santo. presented a rich composition, preying 19 prey types. Orthoptera, Coleoptera, Blattodea most important preys population, Araneae Hemiptera Santo population. The composition differed numerically between localities, but not terms...

The calling activity and agonistic behavior of Pseudis minuta Günther, 1858 were described based on observations made in the Reserva Biológica do Lami, Porto Alegre municipality, Brazil. Field work included bimonthly surveys one semipermanent pond, each lasting approximately two days nights, from August 2004 to July 2005. Males produced three distinct calls: advertisement call aggressive calls. dominant frequency was not correlated with mass or snout-vent length recorded males. We observed...

We studied the reproductive biology of a population Pseudis minuta Günther, 1858 from Reserva Biológica do Lami (30º 15' S; 51º 05' W), Porto Alegre, southern Brazil. assessed spatial and temporal distribution individuals (males, females, juveniles) explored potential relationships with environmental variables. Field activities encompassed bimonthly surveys in three semi-permanent ponds, each one during approximately two days nights, August 2004 to July 2005. recorded differences sites used...

The current note reports the presence of Odontophrynus moratoi at municipality São Carlos, state Paulo, southeastern Brazil. This is third known locality occurence this cycloramphid frog considered threatened extinction.

A new species of the genus Dendrophryniscus is described from Reserva Biológica da Serra Geral, Municipality Maquiné, and Parque Nacional dos Aparados Serra, Cambará do Sul, State Rio Grande Brazil. krausae sp. nov. associated to D. brevipollicatus group characterized by its medium size for (snout-vent length 19.2–21.2 mm in males, 20.4–24.0 females); body robust, slightly enlarged posteriorly; finger I short, males with moderate nuptial pad minuscule dark brown horny asperities; presence...

The C-C motif chemokine ligand 16 (CCL16) is a potent pro-inflammatory and chemoattractant for monocytes lymphocytes. In normal plasma, it present at high concentrations elicits its effects on cells by interacting with cell surface receptors. the European rabbit in rodents such as mouse, rat guinea pig, CCL16 was identified pseudogene, while thirteen-lined ground squirrel appears to be potentially functional. To gain insight into evolution of this gene superorder Glires (rodents lagomorphs),...

Abstract: The Parque Nacional da Tijuca in Rio de Janeiro, Brazil, is considered to be one of the world’s largest urban forests, however no systematic inventory its herpetofauna available. In present study, we surveyed amphibians and reptiles this park assess species composition (including secondary data) obtain estimates richness abundance. We conducted active searches (460 hours) between January 2013 December 2015. identified taxa endemic either Atlantic Forest or Janeiro state, verified...

The tadpole of Sphaenorhynchus palustris is described and illustrated from Municipality Porto Seguro, State Bahia, Brazil. tadpoles are very similar, however the S. promptly distinguished other already species by its long spiracular tube. We also describe advertisement call palustris, same locality. It a short trill, consisting 1 to 3 pulsed notes; note duration varies 0.01 0.05 s interval 0.15 0.19 s; dominant frequency was about 2.62 ± 0.2 kHz. Atlantic Rain Forest southern Bahia one...

Context Species of the tropical frog Family Hylodidae tend to be restricted streams and, hence, have a small occupancy area. Hylodes fredi (Canedo and Pombal 2007), diurnal stream-dwelling species endemic Atlantic Forest in Ilha Grande, south-eastern Brazil, is one such species. Because scarce population studies, it also categorised as Data Deficient (DD) IUCN Red List. Previous studies on habitat use by this did not account for imperfect detection, which could led biased results.Aims We...

The new-generation 454 GS-FLX Titanium pyrosequencing was used to isolate microsatellite markers for the Brazilian Guanabara frog, Euparkerella brasiliensis, an Atlantic forest endemic species.Three multiplex polymerase chain reaction sets were optimized genotyping of 11 polymorphic (di-and tetranucleotide) markers.Genetic diversity assessed in 21 individuals from a population (Reserva Ecológica de Guapiaçu, REGUA) located ©FUNPEC-RP www.funpecrp.com.br

Abstract Miniaturisation is an important evolutionary trend for amphibians and has occurred several times in independent anuran lineages. Most miniaturised frogs live the leaf litter of tropical forests have terrestrial reproductive modes. They are expected to reduced fecundity number eggs than larger-bodied related species, but little known about cycles proportion females. Lower vagility also assumed, however, as they difficult observe, there empirical evidence their dispersal. We studied...
