Redundant or complementary? Identifying patterns of multifaceted frog and toad biodiversity in the eastern United States
Biodiversity at its core describes variation among organisms. It is often quantified as species richness, with a high number of co-occurring species designating important ‘hotspots’. However, variation among organisms is not limited to species diversity. Other facets of biodiversity, including life history and phylogenetic diversity, may occur parallel to richness or may be independently distributed spatially. Considering multiple facets may be vital to understand the distribution of biodiversity’s functional and adaptive components, particularly if those facets do not co-occur with richness. We characterized spatial patterns and environmental drivers of species, phylogenetic, and life history diversity of anurans (frogs and toads) in the eastern United States. We measured richness by building species distribution models (SDMs) to estimate the range of 27 anurans of the eastern US using publicly available occurrence and environmental data. We used phylogenetic data and a recently published anuran trait dataset to characterize phylogenetic and life history diversity. Finally, we compared patterns and drivers among facets to quantify areas of redundancy and complementarity. Measuring biodiversity as a multifaceted concept improves our understanding of why anurans occur where they do and can help inform more comprehensive and multidimensional conservation.
