Anurans from the Serra da Bocaina National Park and surrounding buffer area, southeastern Brazil

Here, we review the species of anuran amphibian from the Serra da Bocaina National Park and its buffer area, in the Atlantic Forest of southeastern Brazil, comparing the data from a recent survey with museum records. We surveyed adult and larval anurans in ponds, marshes, and streams discontinuously from May 2008 to January 2011. In total, 63 anuran species were previously known to occur at the Park and its surrounding buffer area. In our survey, we recorded 46 species, of which five represented new records, and 22 appeared only in the historical list. Seven topotypic populations were not found in the present study. We suggest that conservation strategies for anurans in the Serra da Bocaina should also consider the surrounding areas that are subjected to anthropogenic pressure, due to the high diversity recorded, high altitudinal variation in species distribution, and various vegetation formations.

Amphibians of grasslands in the state of Paraná, southern Brazil (Campos Sulinos)

Amphibian conservation depends on knowledge about species composition and distribution. This emphasizes the need for inventories, especially in poorly sampled areas. This is the case of Southern grasslands (Campos Sulinos) associated with Araucaria forest in the state of Paraná, southern Brazil. We sampled amphibians in 105 environments from 2004 to 2013 using transect sampling, active search and surveys at breeding sites. We found 61 anuran species and two caecilians. This is the first comprehensive list of amphibian species inhabiting grasslands in Paraná. This landscape deserves high conservation priority before these natural grasslands vanish.

Levantamento da helmintofauna de Hypsiboas albomarginatus e Scinax hayii (Anura: Hylidae) da Ilha Anchieta, município de Ubatuba, SP

Os anfíbios ocupam grande variedade de microhabitats refletindo os diversos modos reprodutivos, estilos de vida e parasitas que estes animais apresentam. Os parasitas são indicativos de muitos aspectos biológicos de seus hospedeiros, incluindo a dieta, ocupação do habitat e a filogenia, podendo também ser bons indicadores diretos do estado de qualidade ambiental. A Ilha Anchieta, parque estadual em área de Mata Atlântica, torna-se interessante para estudos biológicos devido a sua dinâmica insular e isolamento geográfico. No Brasil, a Mata Atlântica é um dos biomas mais afetados pelas atividades antrópicas e o número de helmintos recém-descobertos podem estar desaparecendo mais rapidamente do que novos organismos são descobertos. O objetivo deste estudo foi caracterizar a helmintofauna de duas espécies de anfíbios, Hypsiboas albomarginatus (n=23) e Scinax hayii (n=18), ambas pertencentes à família Hylidae, procedentes da Ilha Anchieta, São Paulo, Brasil. A helmintofauna foi composta apenas de nematoides (Rhabdias sp., Physaloptera sp.) e um espécime não identificado da família Cosmocercidae. Estudos como estes são importantes, pois os parasitas representam uma diversidade oculta, a qual contribui com a manutenção da diversidade local de hospedeiros e das funções do ecossistema

Linking genetic and environmental factors in amphibian disease risk

A central question in evolutionary biology is how interactions between organisms and the environment shape genetic differentiation. The pathogen Batrachochytrium dendrobatidis (Bd) has caused variable population declines in the lowland leopard frog (Lithobates yavapaiensis); thus, disease has potentially shaped, or been shaped by, host genetic diversity. Environmental factors can also influence both amphibian immunity and Bd virulence, confounding our ability to assess the genetic effects on disease dynamics. Here, we used genetics, pathogen dynamics, and environmental data to characterize L.yavapaiensis populations, estimate migration, and determine relative contributions of genetic and environmental factors in predicting Bd dynamics. We found that the two uninfected populations belonged to a single genetic deme, whereas each infected population was genetically unique. We detected an outlier locus that deviated from neutral expectations and was significantly correlated with mortality within populations. Across populations, only environmental variables predicted infection intensity, whereas environment and genetics predicted infection prevalence, and genetic diversity alone predicted mortality. At one locality with geothermally elevated water temperatures, migration estimates revealed source-sink dynamics that have likely prevented local adaptation. We conclude that integrating genetic and environmental variation among populations provides a better understanding of Bd spatial epidemiology, generating more effective conservation management strategies for mitigating amphibian declines.
