Global amphibian declines outpace the loss of most organisms on Earth. The panzootic fungal disease chytridiomycosis, caused by Batrachochytrium dendrobatidis ( Bd ), is widely regarded as a predominant driver behind amphibian biodiversity erosion. However, a comprehensive global‐scale analysis of the relationship between Bd and extinction risk remains lacking. Using a global database of Bd ‐detections and IUCN Red List extinc...

Amphibian larvae can affect the structure and functioning of freshwater ecosystems, but their effects have been little explored although amphibian biodiversity is rapidly declining. Given that larvae of different amphibian species belong to different trophic levels, their effects on freshwater communities and processes can be expected to differ, with herbivores likely having direct effects on algae and predators having indirec...

Because host species tend to harbor multiple parasitic species, coinfection in a host is common. The chytrid fungus Batrachochytrium dendrobatidis (Bd) and the viruses in the genus Ranavirus (Rv) are responsible for the decline of amphibians worldwide. Despite wide geographical co‐occurrence and the serious conservation problem that coinfection with these pathogens could represent, little is known about their possible synergis...

Chytridiomycosis is affecting hundreds of amphibian species worldwide, but while in tropical areas, adult individuals have been the focus of most investigations, the exact role played by infection intensity of breeding adults is not well understood in temperate areas. We conducted mark–recapture–capture surveys during spiny common toad breeding seasons from 2006 to 2018 at the site of the first recorded outbreak of chytridiomy...

Chytridiomycosis, the disease caused by the fungal pathogen Batrachochytrium dendrobatidis ( Bd ), has been unambiguously implicated in the decline of amphibian populations worldwide. However, the impact of this devastating infectious disease can be difficult to gauge without empirical data on the population-level effects of Bd . Often, assessments of the amphibian chytridiomycosis panzootic are based primarily on expert opini...

Infectious disease and climate change are considered major threats to biodiversity and act as drivers behind the global amphibian decline. This is, to a large extent, based on short‐term studies that are designed to detect the immediate and strongest biodiversity responses to a threatening process. What few long‐term studies are available, although typically focused on single species, report outcomes that often diverge signifi...

Amphibian chytridiomycosis, caused by the chytrid fungus Batrachochytrium dendrobatidis ( Bd ), is an emerging infectious disease that widely threatens amphibian biodiversity. However, population‐level outcomes following the introduction of the pathogen are highly context dependent and are mediated by a broad suite of biotic and abiotic variables. Here, we examine the effect of the introduction of Bd on native island populatio...

Chytridiomycosis, the emerging disease caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd) is responsible for declines and extirpations of amphibian populations worldwide. Environmental covariates modify the host‐Bd interaction and thus affect the ongoing spread of the pathogen. One such covariate may be the intensity of ultraviolet B (UV‐B) radiation. In a field experiment conducted in Laguna Grande de Peñalara (...
