The Larger the Egg, the Safer the Nest: A Study on the Negative Correlation Between Nest Predation Rates and Egg Size of Two Tropical Phasianids in Hainan

Ecology and Evolution, Volume 16, Issue 5, May 2026.
There is a lack of research on the predation of tropical pheasant nests. The study conducted artificial nest experiments based on egg size and we have supported the viewpoint that using experimental eggs matched in size with those of natural eggs improves the accuracy of artificial nest simulation studies. ABSTRACT Nest predation is the principal cause

Corticosterone as a Physiological Biomarker: Decoding the Environment‐Cort‐Energy Paradigm

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Corticosterone (cort) is increasingly used as a biomarker in wildlife conservation, though debate remains over which measures best capture physiological and environmental relationships. Using structural equation modeling on a 14‐year dataset, we evaluated the total hormone, free hormone, and CBG profile hypotheses linking cort, energetic state, and ...

Fifty Years Later, and We Still Don't Know About Badges of Status

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Overall, aggression and coloration are positively associated across species, but the generality of this relationship is low, the relationship depends on effect size origin, and the dataset requires further verification, which raises methodological concerns.

Seasonality and Grazing Exclusions Shape Bird Community Dynamics in West African Drylands

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Seasonal changes, more than grazing exclusions, shape bird community composition in the Sahel region of Burkina Faso. However, grazing exclusions enhanced habitat heterogeneity, supporting regional bird biodiversity and providing seasonal refuges that mitigate the effects of overgrazing.

Seasonal Dynamics of the Gut Microbiome in Urban Feral Pigeons Are Associated With Environmental Conditions, Not With Diet Shifts

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Using feral pigeons in urban environments, we show that microbiome diversity and composition vary seasonally despite stable diet composition. ABSTRACT Gut microbiomes play a crucial role in host physiology and seasonal adaptation. While seasonal shifts in avian gut microbiota are often attributed to seasonal diet variation, environmental factors may be
