Juvenile agile frogs spatially avoid ranavirus-infected conspecifics, but do not show generalized social distancing or self-isolation

The paper shows that juvenile agile frogs avoid infected conspecifics but do not isolate themselves, suggesting spatial avoidance may reduce disease transmission while lack of self-isolation may not be pathogen-driven.

Effects of mild winter conditions and two pyrethroid insecticides on the development and survival of juvenile common toads (Bufo bufo)

This study examines the combined effects of pyrethroid insecticides and winter conditions on juvenile common toads, finding that mild winters reduce mortality and that insecticide exposure does not significantly affect survival or morphology.

Tadpoles develop elevated heat tolerance in urban heat islands regardless of sex

This study finds urban-dwelling tadpoles have higher heat tolerance than woodland ones, but this difference disappears in a common-garden experiment, suggesting phenotypic plasticity drives the response, with no sex effect on heat tolerance.

Amphibian larvae benefit from a warm environment under simultaneous threat from chytridiomycosis and ranavirosis

The study examines how elevated temperatures affect co-infection by Bd and Rv in amphibian larvae, finding that higher temperatures reduce pathogen prevalence and increase survival.

"Heat waves" experienced during larval life have species-specific consequences on life-history traits and sexual development in anuran amphibians

This study examines how heat waves during larval stages affect life-history traits and sexual development in two amphibian species, showing species-specific and timing-dependent effects.

Sex reversal and ontogeny under climate change and chemical pollution: are there interactions between the effects of elevated temperature and a xenoestrogen on early development in agile frogs?

This study examines the combined effects of elevated temperature and a xenoestrogen on sex reversal and fitness traits in agile frogs, finding non-additive interactions affecting body mass.

A new molecular method for the exploration of hybrid zones between two toad species of conservation interest

The paper describes a new molecular method to study hybrid zones between Fire-bellied and Yellow-bellied toads, revealing range expansion and hybridization patterns in the Carpathian Basin.
