Temporal, species‐specific variation in activity patterns of bats (Chiroptera) along a boreal river basin in Västerbotten, Sweden

Wildlife Biology, EarlyView.
Seasonal variation in photoperiods, energetic demands, and reproductive constraints are expected to strongly influence bat activity at high latitudes, yet empirical evidence from boreal systems is limited. We used passive acoustic monitoring to examine spatial, temporal, and feeding activity patterns of bats along a boreal river basin in Sweden (64°N ...

Interannual dynamic resource selection patterns of the northern bobwhite in a region with poor edaphic conditions

Wildlife Biology, EarlyView.
Understanding an organism's shifting resource needs throughout its life cycle is crucial for developing effective conservation strategies. Northern bobwhite Colinus virginianus populations have been declining for nearly a century due largely to habitat loss/degradation.

Diet, phenology and body size shape nutrient release by songbirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Global meta‐analysis reveals urban‐associated behavioural differences among wild populations

Journal of Animal Ecology, EarlyView.
Urbanization drives rapid phenotypic change, yet broad patterns of behavioural responses remain unclear. Using a global phylogenetic meta‐analysis, we show urban populations exhibit increased boldness, aggression, exploration and activity—especially in birds—highlighting consistent behavioural shifts and revealing major taxonomic gaps that limit our ...
