Global patterns and drivers of beta diversity facets of reef fish faunas

Aim: Exploring the relationships between the different facets of beta diversity and both past and current environmental conditions can unveil the processes that have shaped spatial patterns of biodiversity. In the marine realm, large-scale patterns and processes of beta diversity have been less investigated. Our study aimed to investigate the patterns and drivers of multiple facets of beta diversity and its components, contrasting pairs of reef fish assemblages among marine realms.
Location: Tropical reefs.
Taxon: Reef fishes.
Methods: Based on trait data and phylogenetic relationships for 5,182 tropical reef fish species, we calculated compositional differences between pairs of reef fish assemblages across the Atlantic, Tropical Eastern Pacific (TEP), and Indo-Pacific realms. We also applied a partitioning approach to distinguish between the turnover and nestedness components. We then evaluated the relative importance of several variables related to historical and contemporary environm..., ,
