Availability of pure cultures of Bd isolates is essential for experimental studies to understand the ecology of this pathogen. We evaluated the relationships of body length of Hylodes cf. ornatus and Lithobates catesbeianus tadpoles to depigmentation of mouthparts and determined if dekeratinization indicated an infection by Batrachochytrium dendrobatidis. A strong association existed for both species, one from South America (Brazil: São Paulo) and one from North America (USA: Maine). We believe it prudent not to kill adult amphibians if avoidable, thus obtaining tissue for isolating Bd from tadpoles is reasonable because infected specimens of some species can be selectively collected based on depigmentation of mouthparts.

To date, the fungus has been found in Africa, the Americas, Australia, and Europe. However, it has never been reported to occur in the Atlantic forest or Brazil. Based on morphologi- cal, histological, and molecular data, we encountered evidence of B. dendrobatidis infection in a high-altitude stream-dwelling Brazilian anuran species, Hylodes magalhaesi (Leptodactylidae). One population (Municipality of Camanducaia, State of Minas Gerais) was surveyed from 2001 to 2005. Tadpoles lacking teeth were observed and collected in 2004. Histological and molecular analyses identified infection by B. dendro- batidis. Although infected tadpoles seem nowadays to co-exist with the disease, our results are alarming due to the highly endangered situation of the Brazilian Atlantic forest and its fauna. -

P OMBAL JR., GUSTAVO M. PRADO, AND CLARISSA CANEDO Departamento de Vertebrados, Museu Nacional/UFRJ, Quinta da Boa Vista, 20940-040 Rio de Janeiro, Rio de Janeiro, Brasil ABSTRACT.—Herein is described a new species of leptodactylid frog from Pedra Azul, Municipality of Domingos Martins, State of Espı´rito Santo, southeastern Brazil. The new species is a member of the genus Megaelosia, and is characterized by large size; fold of fifth toe not reaching outer metatarsal tubercle; snout rounded in dorsal view and slightly protruding in lateral view; tympanum moderately small; finger tips with scutes fused to the subunguis and toe tips with a pair of scutes free of the subunguis; dorsal skin texture smooth; skin of the flanks without large granules; belly and throat predominantly gray with many, small yellow blotches; and distinct bilateral vocal sacs in males. The tadpole is described. The new species is the northern limit for the genus Megaelosia, and reinforces the high endemism and richness of the anuran fauna from Santa Teresa region, State of Espı´rito Santo, Brazil. The subfamily Hylodinae Gu¨ nther, 1859 MATERIALS AND METHODS (Leptodactylidae) is composed of three genera: Specimens used in the description or examined Crossodactylus Dume´ril and Bibron, 1841; Hylodes for comparisons are housed in the Adolpho Lutz Fitzinger, 1826; and Megaelosia Miranda-Ribeiro, collection, deposited in Museu Nacional, Rio de 1923 (Lynch, 1971; Frost, 1985). -
Métodos De Amostragem Da Herpetofauna: Algumas Dicas E Orientações Para Estudantes E Profissionais Com Pouca Ou Nenhuma Experiência De Campo
MÉTODOS DE AMOSTRAGEM DA HERPETOFAUNA: ALGUMAS DICAS E ORIENTAÇÕES PARA ESTUDANTES E PROFISSIONAIS COM POUCA OU NENHUMA EXPERIÊNCIA DE CAMPO. Pedro Costa Diniz¹ Ricardo Oliveira Latini² RESUMO Em pesquisas e muitos estudos de fauna são necessárias coletas de dados em campo para a geração de informações, sobretudo os diagnósticos de espécies. A definição e execução de métodos de amostragens da fauna são de extrema importância para a coleta de dados e para a geração de informações que visem à conservação de espécies e a minimização das ameaças à diversidade biológica. Muitos estudos, não apresentam resultados confiáveis, o que pode estar associado à baixa qualidade de profissionais disponíveis no mercado e uma grande demanda de trabalhos de campo. Outro fator que pode influenciar bastante, é a feitura de estudos e pesquisas totalmente relacionadas à inventário e monitoramento de fauna, sendo feita por profissionais que não se encaixam no perfil, mas que podem exercer a mesma função de um biólogo, tais como engenheiros florestais, engenheiros ambientais, zootecnistas, entre outros. Esse trabalho visa descrever alguns métodos de amostragem da herpetofauna, apresentando dicas e informações que contribuam com a execução de pesquisas em campo. Para isso foram realizadas pesquisas bibliográficas e compilados os métodos disponíveis nos artigos triados. Foram selecionados e descritos sete métodos de amostragem da herpetofauna. Inicialmente, foram apresentadas algumas informações gerais que dizem respeito à etapa prévia às atividades de campo e, em seguida, uma descrição dos métodos de amostragens geralmente utilizados para a realização de estudos da herpetofauna. É esperado que os resultados apresentados nesse estudo contribuam com o planejamento e execução de estudos da herpetofauna por profissionais e estudantes 1 - Graduando em Ciências Biológicas pelo Centro Universitário Metodista Izabela Hendrix. -
Nitrogen Cycling During Secondary Succession in Atlantic Forest of Bahia, Brazil Received: 31 August 2017 Joy B
www.nature.com/scientificreports OPEN Nitrogen cycling during secondary succession in Atlantic Forest of Bahia, Brazil Received: 31 August 2017 Joy B. Winbourne1, Aida Feng1, Lovinia Reynolds1, Daniel Piotto2, Meredith G. Hastings1,3 & Accepted: 21 December 2017 Stephen Porder1 Published: xx xx xxxx Carbon accumulation in tropical secondary forests may be limited in part by nitrogen (N) availability, but changes in N during tropical forest succession have rarely been quantifed. We explored N cycle dynamics across a chronosequence of secondary tropical forests in the Mata Atlântica of Bahia, Brazil in order to understand how quickly the N cycle recuperates. We hypothesized that N fxation would decline over the course of succession as N availability and N gaseous losses increased. We measured N fxation, KCl-extractable N, net mineralization and nitrifcation, resin-strip sorbed N, gaseous N emissions and the soil δ15N in stands that were 20, 35, 50, and > 50 years old. Contrary to our initial hypothesis, we found no signifcant diferences between stand ages in any measured variable. Our fndings suggest that secondary forests in this region of the Atlantic forest reached pre-disturbance N cycling dynamics after just 20 years of succession. This result contrasts with previous study in the Amazon, where the N cycle recovered slowly after abandonment from pasture reaching pre-disturbance N cycling levels after ~50 years of succession. Our results suggest the pace of the N cycle, and perhaps tropical secondary forest, recovery, may vary regionally. More than half of extant tropical forests are regenerating from disturbance1 and in the coming decades these re-growing forests will be a substantial carbon sink (~1 Pg yr−1)2, provide habitat for myriad species, and food, fuel and fber for millions of people2. -

Hybrids of Amphibian Chytrid Show High Virulence in Native Hosts S

Haddad4 & C. G. Becker1 Received: 4 April 2018 Hybridization of parasites can generate new genotypes with high virulence. The fungal amphibian Accepted: 6 June 2018 parasite Batrachochytrium dendrobatidis (Bd) hybridizes in Brazil’s Atlantic Forest, a biodiversity Published: xx xx xxxx hotspot where amphibian declines have been linked to Bd, but the virulence of hybrid genotypes in native hosts has never been tested. We compared the virulence (measured as host mortality and infection burden) of hybrid Bd genotypes to the parental lineages, the putatively hypovirulent lineage Bd-Brazil and the hypervirulent Global Pandemic Lineage (Bd-GPL), in a panel of native Brazilian hosts. In Brachycephalus ephippium, the hybrid exceeded the virulence (host mortality) of both parents, suggesting that novelty arising from hybridization of Bd is a conservation concern. In Ischnocnema parva, host mortality in the hybrid treatment was intermediate between the parent treatments, suggesting that this species is more vulnerable to the aggressive phenotypes associated with Bd-GPL. Dendropsophus minutus showed low overall mortality, but infection burdens were higher in frogs treated with hybrid and Bd-GPL genotypes than with Bd-Brazil genotypes. Our experiment suggests that Bd hybrids have the potential to increase disease risk in native hosts. Continued surveillance is needed to track potential spread of hybrid genotypes and detect future genomic shifts in this dynamic disease system. Te host-parasite dynamic is a classic example of an evolutionary arms race; hosts face pressure to evolve defenses against parasites, while parasites face pressure to overcome host defenses1,2. -

These Amphibia choices can strongly affect the resulting topologies. Here, we explore two controversial approaches (binning Anura genes into “supergenes” and inclusion of only rapidly evolving sites), using new data from hyloid frogs. Hyloid Biogeography frogs encompass ∼53% of frog species, including true toads (Bufonidae), glassfrogs (Centrolenidae), poison Naive binning frogs (Dendrobatidae), and treefrogs (Hylidae). Many hyloid families are well-established, but relationships Phylogenomics among these families have remained difficult to resolve. We generated a dataset of ultraconserved elements Statistical binning (UCEs) for 50 ingroup species, including 18 of 19 hyloid families and up to 2214 loci spanning > 800,000 aligned base pairs. -
