Dispersal ability determines the scaling properties of species abundance distributions: a case study using arthropods from the Azores

Abstract Species abundance distributions (SAD) are central to the description of diversity and have played a major role in the development of theories of biodiversity and biogeography. However, most work on species abundance distributions has focused on one single spatial scale. Here we used data on...
