2022-11-15 Data for Functional and phylogenetic relationships link predators to plant diversity via trophic and non-trophic pathways doi:10.57760/sciencedb.06389 en Based on a comprehensive dataset of spiders recorded from the BEF sites, we tested the direct (potentially non-trophic) and indirect (via trophic cascades) links between tree diversity and arthropod predator diversity by deconstructing the relationships among multiple components (taxonomic, phylogenetic and functional) of their diversities. Our study highlights the importance of an integrated approach based on multiple biodiversity components in understanding the consequences of biodiversity loss in multitrophic communities.
