Influence of community connectivity and genetic diversity of an exotic consumer on invasion success in metacommunities

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Genetic diversity of potentially invasive exotic species has been theorized to lead to increased invasion success. However, empirical work investigating this relationship is extremely limited, especially in the context of metacommunity connectivity. Native community connectivity may mitigate the effects of invasion, but such protective effects

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

Biotropica, 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 ...
