Unveiling Wasps as Potential Pollinators: Floral Traits and Wasp Sociality Intensify Network Centrality in a Highly Diverse Tropical Ecosystem

Journal of Applied Entomology, Volume 149, Issue 10, Page 1520-1531, December 2025.
ABSTRACT Wasps, members of over 90 hymenopteran families, exhibit diverse behaviours, including pollination, predation and parasitism. While wasps are known pollinators in specialised systems, such as the intricate mutualism of fig trees and the deceptive pollination of certain orchids, they have historically been considered ineffective pollinators ...

The Cost of Self‐Defense: Browsing Effects in the Rare Plant Species Salix arizonica

Ecology and Evolution, Volume 14, Issue 11, November 2024.
Willows with physical protection from ungulate browsing for multiple years had significantly lower phenolic glycoside (PG) concentration and increased plant height compared to unprotected individuals. In contrast, changes in levels of defense were not observed when plants received protection for only one growing season.
