The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice.
It is shown that small-sized frogs often emit calls with frequency components in the ultrasound spectrum, although it is unlikely that these high frequencies are of biological relevance for the majority of them, and it is illustrated that detection of upper harmonics depends also on recording distance because higher frequencies are attenuated more strongly.
Novel, panzootic and hybrid genotypes of amphibian chytridiomycosis associated with the bullfrog trade
The finding that Bd is capable of sexual reproduction between panzootic and endemic genotypes emphasizes the risk of international wildlife trade as a source of additional Bd epizootics owing to hybridization.
Behavioural defences of anurans: an overview
The role of predators in the evolution of defensive behaviours is still scarcely touched upon and this overview adds data to explore this and other evolutionary unsolved questions.
Amphibian fungal panzootic causes catastrophic and ongoing loss of biodiversity
A global, quantitative assessment of the amphibian chytridiomycosis panzootic demonstrates its role in the decline of at least 501 amphibian species over the past half-century and represents the greatest recorded loss of biodiversity attributable to a disease.
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…

The classification of anuran vocalization into three major categories: reproductive, aggressive, and defensive calls is proposed, subdivided according to the social context of emission mostly reflecting also acoustic differences among call types.
Disentangling host, pathogen, and environmental determinants of a recently emerged wildlife disease: lessons from the first 15 years of amphibian chytridiomycosis research
The ecology and evolution of Bd in the Americas is reviewed and controversies that make this disease so enigmatic are highlighted and the concept of “the Ghost of Epizootics Past” is introduced to discuss expected patterns in postepizootic host communities.
Anurans as prey: an exploratory analysis and size relationships between predators and their prey
The vertebrate predators of post-metamorphic anurans were quantified and the predator–prey relationship was investigated by analysing the relative size of invertebrate predators and anuran, showing an increase in the Relative size of the prey when predators used special predatory tactics.

Is it all death feigning? Case in anurans
It is believed that there is more than one behaviour type referred to as thanatosis, and definitions and new names that complement the present knowledge on the subject are proposed.
