Responses of insect pollinators to habitat fragmentation: A global meta-analysis

Insect pollinators are declining globally, with habitat fragmentation recognized as an important driver. While these declines have garnered widespread public and policy attention, current evidence remains largely limited to certain taxa, geographic regions, and ecosystems, thereby resulting in diverse outcomes.
Here, we aimed to present a global meta-analysis using a dataset comprising 80 studies across 28 countries on all continents, excluding Antarctica. We used Pearson’s correlation coefficient (r) as an effect size to measure the association between habitat fragmentation and the abundance and species richness of wild bees, butterflies, and wasps. Subsequently, we performed categorical meta-analyses that fragmentation indices, climates, and taxonomic groups as moderators to investigate the dependency of habitat fragmentation effects on these factors.
Increasing habitat fragmentation was significantly associated with reductio..., , # Data from: Responses of insect pollinators to habitat fragmentation: A global meta-analysis
