Recent Asian origin of chytrid fungi causing global amphibian declines
Panzootic chytrid fungus out of Asia Species in the fungal genus Batrachochytrium are responsible for severe declines in the populations of amphibians globally. The sources of these pathogens have…
Widespread presence of the pathogenic fungus Batrachochytrium dendrobatidis in wild amphibian communities in Madagascar
Results may suggest that Bd arrived recently, but do not exclude the existence of a previously undetected endemic Bd genotype, which could pose significant threats to Madagascar's unique “megadiverse” amphibians.
Phylogeny and Differentiation of Reptilian and Amphibian Ranaviruses Detected in Europe
Comparative analyses show that among the closely related amphibian-like ranaviruses (ALRVs) described to date, three recently split and independently evolving distinct genetic groups can be distinguished.
From fish to frogs and beyond: Impact and host range of emergent ranaviruses.
Impact of asynchronous emergence of two lethal pathogens on amphibian assemblages
It is found little evidence that pre-existing chytrid emergence was associated with ranavirus and the emergence of ranavirosis, and co-infection dynamics have been largely overlooked in an amphibian assemblage in Serra da Estrela.
Can leftovers from predators be reliably used to monitor marine turtle hatchling sex-ratios? The implications of prey selection by ghost crabs
It is shown that ghost crabs select the smaller prey, but do not select according to hatchling sex, which is explained by the lack of hatchling size dimorphism in this population of sea turtles.
Host species vary in infection probability, sub-lethal effects, and costs of immune response when exposed to an amphibian parasite
It is suggested that populations of resistant species are likely to suffer ill-effects of exposure to Bd regardless of their infection status, and that at the stage of initial infection there was no support for the dilution of transmission events, in contrast to other studies that focus on subsequent transmission of infection.

This observation adds a new prey item to the T. cirrhosus diet and shines some light on the scarce ecological knowledge of both predator and prey species.
Living within fallen palm leaves: the discovery of an unknown Blommersia (Mantellidae: Anura) reveals a new reproductive strategy in the amphibians of Madagascar

A new mantelline frog of the genus Blommersia found in rainforest in North East Madagascar, from the protected areas of Ambatovaky, Betampona, Masoala, and Zahamena is described, which represents a new evolutionary lineage of Malagasy frogs in which phytotelmy is known.
First Reports of Leech Parasitism in Malagasy Anurans
This study represents the first description of amphibian–leech interactions in Madagascar, the second report of leeches as ectoparasites of Malagasy vertebrates, and the fourth reference of haemadipsid as amphibian parasites.
