TL;DR: This article used whole-genome sequencing to solve the spatiotemporal origins of the most devastating panzootic to date, caused by the fungus Batrachochytrium dendrobatidis, a proximate driver of global amphibian declines.
Journal ArticleDOI
Determinants and consequences of dispersal in vertebrates with complex life cycles: A review of pond-breeding amphibians
Hugo Cayuela,Andrés Valenzuela-Sánchez,Andrés Valenzuela-Sánchez,Loïc Teulier,Iñigo Martínez-Solano,Jean-Paul Léna,Juha Merilä,Erin Muths,Richard Shine,Ludivine Quay,Mathieu Denoël,Jean Clobert,Benedikt R. Schmidt +12 more
TL;DR: The concept of amphibian dispersal is redefined and clarified; current knowledge about the effects of individual and environmental factors during the three stages of dispersal are reviewed; and new research avenues are proposed to extend the understanding of amphibians dispersal.
Journal ArticleDOI
Geographic body size variation in ectotherms: effects of seasonality on an anuran from the southern temperate forest
TL;DR: Greater seasonality is expected to drive larger body size, since metabolic rate is reduced further and longer during colder, longer winters, leading to decreased energy depletion during hibernation, improved survival and increased longevity (and hence growth).
Journal ArticleDOI
The Population Decline and Extinction of Darwin’s Frogs
Claudio Soto-Azat,Claudio Soto-Azat,Andrés Valenzuela-Sánchez,Ben Collen,J. Marcus Rowcliffe,Alberto Veloso,Andrew A. Cunningham +6 more
TL;DR: The authors' results provide further evidence that R. rufum is extinct and indicate that Rhinoderma darwinii has declined to a much greater degree than previously recognised, and should be stepped up and the species re-classified as Endangered.
Journal ArticleDOI
Cryptic disease-induced mortality may cause host extinction in an apparently stable host–parasite system
Andrés Valenzuela-Sánchez,Benedikt R. Schmidt,David E. Uribe-Rivera,Francisco Costas,Andrew A. Cunningham,Claudio Soto-Azat +5 more
TL;DR: The results indicate that Bd-induced population extirpation may occur even in the absence of epidemics and where parasite prevalence is relatively low, consistent with previous theoretical predictions showing that highly pathogenic parasites are able to regulate host populations even at extremely low prevalence.
