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.

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.

Does stress make males? An experiment on the role of glucocorticoids in anuran sex reversal

The paper tests if corticosterone mediates sex reversal in frogs and finds no significant dose-effect relationship, but notes urban habitats increase sex reversal and reduce fitness.

"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.

Effects of chlorpyrifos on early development and anti-predator behavior of agile frogs

This study examines the effects of chlorpyrifos on agile frog tadpoles, finding that chronic exposure at high concentrations alters locomotor activity and body mass, but not other traits, suggesting some tolerance to the pesticide.

Novel genetic sex markers reveal unexpected lack of, and similar susceptibility to, sex reversal in free-living common toads in both natural and anthropogenic habitats

The paper develops genetic sex markers to assess sex reversal in common toads across habitats and finds low sex reversal frequency despite endocrine disruptors.

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.
