Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

open access: yesIntegrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Uncovering temporal patterns of wildlife activity, habitat use and habitat preference from camera‐trap data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract An understanding of habitat use and levels of active behaviour is foundational to wildlife behaviour, ecology, conservation and management. These variables are commonly measured by tracking individuals in space and time using biologging. In principle, camera‐trap data also contain information about both activity level and habitat use; however,

Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

open access: yesEthology, EarlyView.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.
