The paper examines how agricultural support schemes, vegetation types, and red fox populations affect European brown hare density in Hungary, finding that hare density is influenced by the proportion of AKG arable land and fox harvest rates.

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.

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

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.

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.

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