The role of insularity: Plants have few ornithophilous traits but are visited by morphologically more distinct hummingbirds in the Caribbean islands

open access: yesFunctional Ecology, Volume 39, Issue 7, Page 1678-1692, July 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits determine interactions between plants and pollinators, and to increase pollination efficiency, many plants have evolved traits to attract specific pollinator groups. However, biogeographical setting may influence trait evolution and biotic interactions.
