Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

Urbanization Intensity, Vegetation Cover and Plant Vigor Affects Stem Galls Occurrence and Abundance in a Widely Distributed Ruderal Tropical Plant

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
In this study, we demonstrate that urbanization intensity reduces the abundance of stem galls on Turnera subulata, while increased vegetation cover and plant vigor promote higher occurrence and abundance. These findings highlight the importance of native vegetation in sustaining specialized insect‐plant interactions and provide evidence that plant ...
