Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Tree traits are a stronger predictor of bee traits and species richness than taxonomic diversity

Functional Ecology, Volume 39, Issue 1, Page 281-292, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits help to understand biological diversity and the mechanism by which ecological communities are structured and how they respond to the environment. For example, the high tree species diversity within tropical forests can be grouped into a few functional ...
