Landscape homogenization strengthens the fitness benefits of plant species' centrality in pollination networks

open access: yesEcological Applications, Volume 35, Issue 5, July 2025.
Abstract Understanding how plant–pollinator interactions vary along disturbance gradients and influence community function is essential to comprehend how pollination services can be maintained in increasingly anthropized landscapes. Recent studies found positive relationships between plant fitness and centrality in interaction networks (i.e., high ...

Seasonal and Landscape‐Driven Variations in Forage Resources of Apis mellifera scutellata: Implications for Pollination Sustainability and Colony Health in Taita Taveta County, Kenya

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
We used DNA metabarcoding to identify nectar and pollen plant species supporting honey bee nutrition across different landscapes and seasons in Taita Taveta County, Kenya. Forage availability was influenced by landscape and season, with exotic species (67%) dominating over native ones (33%), raising concerns about colony health and how the occurrence ...

Social Organization Is Associated With Relaxed Selection on Worker Genes in Highly Polygyne Ants

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
ABSTRACT Ants display a diversity of social structures reflected by differences in caste, nest, and colony organization. Previous research has shown that highly eusocial insects (Hymenoptera) exhibit genome‐wide signatures of relaxed selection due to their smaller effective population sizes.
