Season, Microclimate and Shoreline Disturbance Interactively Shape Bird Functional Diversity

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This study examined the seasonal and spatial patterns of bird functional diversity across natural and urbanized coastal sites in Ghana. We found that natural shorelines undergo significant seasonal functional reorganization, whereas urbanized areas maintain stable, generalist‐dominated communities year‐round, losing the temporal dynamics that support ...

Contemporary Evolution of an At‐Risk Stickleback Population During a Severe Drought

open access: yesEvolutionary Applications, Volume 19, Issue 1, January 2026.
ABSTRACT Populations can be granted conservation status because they harbour a set of unique traits, evolutionary histories, or ecological roles. Such populations are often isolated and specialised and, as such, can be particularly vulnerable to environmental disturbances.

Fishing‐Induced Regulation of Diadromous Fish Subsidies in Stream Communities

open access: yesFreshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Seasonal migrations of diadromous fish transport marine‐derived nutrients into freshwater ecosystems, enriching communities and restructuring food‐web dynamics. By diminishing these migrations, fishing pressure could disrupt cross‐ecosystem connectivity, thereby altering predator–prey interactions and community size structure.
