Photo-based individual identification is more reliable than visible implant elastomer tags or toe tipping in young agile frogs

This study compares photo-based identification with visible implant elastomer tags and toe clipping in young agile frogs, finding photo-based methods significantly more reliable.

Put the frog in water: simple methods for improving individual identification as demonstrated with the agile frog

This paper develops photography methods to improve individual identification of agile frogs using natural environments and body posture, achieving high accuracy with HotSpotter software.

Do pyrethroid insecticides influence sex ratios in agile frogs (Rana dalmatina)?

This study examines the effects of pyrethroid insecticides on sex ratios in agile frogs, finding male-biased phenotypic sex ratios due to female-biased mortality, not sex reversal.

Behavioral anapyrexia as a response to virus infection in a poikilothermic vertebrate

The paper shows that infected tadpoles lower their body temperature more than uninfected ones, suggesting behavioral anapyrexia as a response to virus infection.

Mitigation of chytrid infection on tadpoles with the antimicrobial metabolites of Xenorhabdus szentirmaii

This study tests the effectiveness of Xenorhabdus szentirmaii antimicrobial metabolites in reducing chytrid fungus infection in yellow-bellied toad tadpoles, finding reduced infection intensity but variable efficacy across populations.

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.

Infection with the chytrid fungus (Batrachochytrium dendrobatidis) may distort sex ratio via sex reversal but not sex-dependent mortality in a common Eurasian amphibian

This study investigates whether chytrid fungus infection causes sex ratio distortion in common toads through sex reversal rather than sex-dependent mortality.
