Anthropogenic trade and development have broken down dispersal barriers, facilitating the spread of diseases that threaten Earth's biodiversity. We present a global, quantitative assessment amphibian chytridiomycosis panzootic, one most impactful examples disease spread, demonstrate its role in decline at least 501 species over past half-century, including 90 presumed extinctions. The effects been greatest large-bodied, range-restricted anurans wet climates Americas Australia. Declines...

Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, neglected terms of conservation, and knowledge its fragmented. We aim to answer the question: how many, which, species occur Pampa? In a collaborative effort, we built lists plants, animals, bacteria, fungi that Pampa. included information distribution patterns, main habitat types, status. Our study resulted referenced totaling 12,503 (12,854 taxa, when...

Lizards of the Liolaemus wiegmannii group comprise 11 species that are widely distributed east Andes, occurring in Argentina, Uruguay, and Brazil. Here we analyzed a population genus Liolaemus, found Pampa region on isolated sand dunes along Tacuarembó River. We conducted biometric, meristic, genetic comparisons between this other populations L. weigmannii from Argentina complex. Our morphological analyses showed represents to new belonging group. To date, its known distribution is extremely...

The diet of Leptodactylus ocellatus (L., 1758) was studied in specimens collected at Maldonado Department (Uruguay), where monthly surveys were made between August 1998 and March 2000. A total 143 frogs collected, measured, sexed, dissected, to assess stomach contents. anurans grouped into three age classes four categories (considering sex capture date). trophic amplitude for each class sex-season category quantified using Shannon-Weaver Index, the niche overlap ages by Pianka Index....

Intrapopulation variation includes age and sexual variation, but also individual niche specialization. Individual specialization has important effects on dynamics at population or community levels. Environmental intraspecific interactions are factors that can promote enhance this kind of variation. Despite its relevance, knowledge about in amphibians is still scarce, especially species from temperate regions. In study we analyzed the intrapopulational trophic Hypsiboas pulchellus a southern...

A new bufonid toad is described. The species belongs to the genus Melanophryniscus, and may be largest in this genus. Its size external features (pale green dorsal surface) resemble those of Melanophryniscus cambaraensis macrogranulosus, from which it differs by absence frontal swelling. At present, endemic southern border Brazilian Southern Plateau, central Rio Grande do Sul state.

Individual identification is useful for answering a variety of biological questions about animal life histories. Most the techniques used to mark amphibians are invasive and can cause negative effects, compromising individual survivorship biasing studies. Photo-identification consists in specimens based on photographic records unique color-design patterns. This technique has been with success several amphibian species. Melanophryniscus montevidensis an endangered anuran species inhabiting...

Abstract The uneven spatial distribution of biodiversity is a defining feature nature. In fact, the implementation conservation actions both locally and globally has progressively been guided by identification ‘hotspots’ (areas with exceptional biodiversity). However, different regions world differ drastically in availability fine-scale data on diversity species, thus limiting potential to assess their local environmental priorities. Within South America—a megadiverse continent—Uruguay...

The bufonid toad Chaunus achavali, a recently described species known only from Uruguay, is recorded for Brazil. This morphologically similar to C. ictericus and arenarum, several individuals were labeled in Brazilian scientific collections under these taxa. A lectotype of arenarum designated. Additional field notes on achavali key the identification marinus group are presented.
