Amphibians are the most threatened vertebrate class, with around 40% of all species considered to be globally threatened with extinction. To prevent the extinction of amphibian species and improve their conservation status, people and organizations from all around the world have come together to take organized action. The Admirable Redbelly Toad (M...

The Harlequin Toad (Atelopus) Conservation Action Plan (HarleCAP), created by the Atelopus Survival Initiative, promotes strategies to synchronize efforts and exchange resources, knowledge, and capacities among stakeholders through regional coordination and inter- and multi-disciplinary approaches to: 1) Produce baseline knowledge, 2) Ensure viable...

The Amazon catchment is the largest river basin on earth, and up to 30% of its waters flow across floodplains. In its open waters, floating plants known as floating meadows abound. They can act as vectors of dispersal for their associated fauna and, therefore, can be important for the spatial structure of communities. Here, we focus on amphibian di...

Der Erreger der als Salamanderpest bezeichneten Amphibienhauterkrankung - der Chytridpilz Batrachochytrium salamandrivorans - ist inzwischen an mehreren Standorten in Mitteleuropa (in den Niederlanden, Belgien und Deutschland) nachgewiesen, mit besonders schweren Folgen für die anscheinend sensibelste Wirtsart, den Feuersalamander (Salamandra salam...

We studied the knowledge gap in GenBank with regard to the ca. 600 anuran species from Amazonia. The markers 12S, 16S, COI and cytb were examined, on which information was available for about half of all species. Both the number of sample sites and the number of samples per species varied greatly (best studied each in 16S: 4.85 ± 10.37; 11.19 ± 31....

Although the distribution patterns of major amphibian lineages are mainly explained by a Pangean origin with subsequent vicariant diversification, dispersal events have exerted a strong influence on present-day distributions. Long-distance dispersal (LDD) involves movements outside the standard geographic limits and outside the genetic neighbourhoo...

Museum collections should use 3D printing to create replicas of their most important specimens. This would guard against loss or damage, as has occurred on a massive scale in Brazil. Two of South America’s largest scientific collections have burned down: the National Museum in Rio de Janeiro, in September, and the Butanton Institute in São Paulo in...

RESUMO Estudos sobre distribuição espacial e temporal de anfíbios têm se mostrado importantes para o entendimento das relações entre as espécies e o ambiente. Nesse sentido, constata-se que essas informações acerca de espécies do gênero Sphaenorhynchus Tschudi, 1838 no Rio Grande do Sul ainda não foram levantadas. Esta pesquisa, cujo objetivo princ...

Der Feuersalamander (Salamandra salamandra) ist ein relativ häufiger Bewohner der waldreichen Mittelgebirgslagen von Rheinland-Pfalz. Jedoch sind genaue Verbreitungsdaten rar. Da die Bestände akut durch den eingeschleppten Salamander-Chytridpilz (Batrachochytrium salamandrivorans) bedroht sind, werden durch die Universität Trier seit 2015 verschied...

Since 2000, the Sociedad Zoológica del Uruguay, along with the Uruguayan Committee of IUCN, leads a process to provide the herpetologists with the tools to conduct evaluations using the standardized criteria of IUCN. The new assessment process started in 2013 and followed entirely the IUCN guidelines, categories and criteria. All native amphibian s...

Herein, we provide new occurrence records of Scinax nasicus (Cope, 1862) for the state of Rio Grande do Sul, Southern Brazil. All new records here provide are located on Southern half of the state. Besides this, we provide the first record for species in Brazilian coastal zone. Those records improve considerably our knowledge regarding species dist...

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 in urodeles of different species expands the known geographic and host range of the fungus and underpins its imminent th...

Field sites in Europe at which Batrachochytrium salamandrivorans fungus was and was not detected in amphibians, 2010–2016.

We studied the reproductive biology of a population of Pseudis minuta Günther, 1858 from Reserva Biológica do Lami (30º 15' S; 51º 05' W), Porto Alegre, southern Brazil. We assessed the spatial and temporal distribution of individuals (males, females, juveniles) and explored potential relationships with environmental variables. Field activities enc...

As vocalizações e o comportamento agonístico de Pseudis minuta Günther, 1858 foram descritos com base em observações realizadas na Reserva Biológica do Lami, município de Porto Alegre, Brasil. As atividades de campo compreenderam visitas bimensais com duração aproximada de dois dias e duas noites cada, entre agosto de 2004 e julho de 2005. Os macho...

The hobo transposable element can occur under three forms in the Drosophila genome: as a complete element (also called canonical), as internally deleted copies, or as hobo-related sequences (relics). Some evidence indicated that canonical elements and internally deleted copies are recent acquisitions of Drosophila genomes, while the “relics” are ol...
