Morphological Evolution in Island Birds Is Associated With More Terrestrial Lifestyles and a Lower Number of Raptors and Intra‐Family Competitors

Global Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Aim Island biotas experience unique ecological conditions, such as isolation, small areas, or simplified communities that promote repeated patterns of evolution like changes in body size, that have been widely studied. By contrast, apart from the evolution of flightlessness in birds, changes in body shape remain relatively less explored. Here,

Functional and Phylogenetic Structure of Forest Bird Assemblages Along an Afrotropical Elevational Gradient

Ecology and Evolution, Volume 15, Issue 9, September 2025.
On Mt. Cameroon, functional richness and taxonomic diversity decreased with elevation, while functional nearest neighbor distance, functional evenness, and mean nearest taxon distance showed positive trends. Traits related to resource use indicated that higher‐elevation species were functionally less similar than expected by chance, supporting ...

Effects of Semi‐Natural Habitats on Bird Occupancy in Different Intensity Agriculture: A Multi‐Species Approach

Diversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Agriculture is a primary factor underlying worldwide declines in biodiversity. Incorporating semi‐natural habitat features within agricultural landscapes is considered an effective strategy for mitigating the biodiversity loss associated with agricultural intensification.

Overwintering and Resident Birds in Qatar: Explorations With DNA Barcoding

Ecology and Evolution, Volume 15, Issue 7, July 2025.
We obtained DNA barcodes for 115 birds (34 species, 12 orders) in Qatar, a country with no previous barcode sequence data for wild birds. We provide insights on locally breeding species and overwintering migrants. ABSTRACT Genetic research is unevenly distributed across the globe, with most research done in temperate zones.
