Coinvasional disruptions to island pollinator networks

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

The Most Effective Pollinators Predict Intraspecific Floral Color Diversity Across an Edaphic Matrix

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
A generalist‐pollinated plant endemic to rock outcrops recently expanded to weedy roadside meadow populations where it exhibited reduced flower color variation and less pigmented flowers. A relationship between flower color and pollinator community composition, and an especially strong link between color and relative abundance of the most effective ...

Structural Colour in Bees (Hymenoptera: Anthophila) Is Linked to Climate and Latitude

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 9, September 2026.
ABSTRACT Aim Environmental drivers frequently predict global patterns of colour diversity, but whether such patterns depend on the underlying colour mechanisms—pigments or microscopic structures—has scarcely been considered. Structural colour may have different functional properties that result in different associations with environmental variables ...
