Emerging fungal diseases can drive amphibian species to local extinction. During 2010-2016, we examined 1,921 urodeles in 3 European countries. Presence of the chytrid fungus Batrachochytrium salamandrivorans at new locations and different expands known geographic host range underpins its imminent threat biodiversity.
Although the distribution patterns of major amphibian lineages are mainly explained by a Pangean origin with subsequent vicariant diversification, dispersal events have exerted strong influence on present-day distributions. Long-distance (LDD) involves movements outside standard geographic limits and genetic neighbourhood area individuals. considered 'rare', LDD is disproportionately important to populations, species communities. To understand role in shaping current biogeographic these...
The Amazon catchment is the largest river basin on earth, and up to 30% of its waters flow across floodplains. In open waters, floating plants known as meadows abound. They can act vectors dispersal for their associated fauna and, therefore, be important spatial structure communities. Here, we focus amphibian diversity in Amazonian over large scales. We recorded 50 species 57 sites, covering around 7000 km along courses. Using multi‐site generalised dissimilarity modelling zeta diversity,...

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...
Herein, we provide new occurrence records of Scinax nasicus (Cope, 1862) for the state Rio Grande do Sul, Southern Brazil. All here are located on half state. Besides this, first record species in Brazilian coastal zone. Those improve considerably our knowledge regarding distribution
Ceratophrys ornata is an iconic and regionally threatened amphibian of the temperate grasslands from Argentina, Brazil, Uruguay. Conservation assessments suggested that habitat loss main threat to species, although no studies have yet explored link between grassland replacement C. decline. Using a robust database with ∼1000 records herpetological collections, citizen science, long-term monitoring, we modeled species' ecological niche produce map suitable areas, where searched for using...
RESUMO Estudos sobre distribuição espacial e temporal de anfíbios têm se mostrado importantes para o entendimento das relações entre as espécies ambiente. Nesse sentido, constata-se que essas informações acerca do gênero Sphaenorhynchus Tschudi, 1838 no Rio Grande Sul ainda não foram levantadas. Esta pesquisa, cujo objetivo principal foi a caracterização da surdus (Cochran, 1953) durante atividade vocalização, bem como análise dos principais fatores climáticos associados essa atividade,...
