Patterns of α‐, β‐ and γ‐diversity of terrestrial vertebrates in continental scale

Abstract

Biodiversity is not randomly distributed in space and understanding of diversity patterns can shed light on the factors and processes that shape it. The aim of this thesis is to detect and study spatial diversity patterns. Using an alternative sampling method, I estimated the area that contains a specified number of species (minA) and the species-area relationship (SAR) resulting from minA (Chapter 1). The spatial patterns of different diversity dimensions (α-, β- and γ-diversity) vary with the scale of observation (Chapter 2). The scale of observation depends on the taxonomic group’s characteristics, while differences between the human and taxonomic group’s scale of observation could add noise to the observed patterns. The sampling design is defined by the researcher and affects the spatial patterns. Contrariwise, the sample size and shape in the minA approach are defined by the species presence data eliminating the scale effect. The minA is defined as the minimum convex hull having a ...
