Phylogenetic Diversity across Space and Time
Phylogenetic Diversity across Space and Time
This chapter examines how phylogenetic diversity changes across spatial and temporal gradients. Spatial ecophylogenetic patterns can reveal how different processes shape ecological communities. Metacommunity ecology reinvigorated the search for general mechanisms that create diversity and structural differences among communities, and by using phylogenetic patterns we can understand how shared traits and evolution inform community differences. The chapter first considers phylobetadiversity as a measure of phylogenetic turnover before discussing two types of phylobetadiversity metrics, diversity partitioning and pairwise distances. It also analyzes the influence of spatial scale on phylogenetic patterns, focusing on the scale dependency of phylogenetic patterns, and concludes with an overview of phylogenetic diversity–area relationships.
Keywords: phylogenetic diversity, phylogenetic patterns, phylobetadiversity, phylogenetic turnover, diversity partitioning, pairwise distances, spatial scale, scale dependency, phylogenetic diversity–area relationships
