Quantifying individual differences in dispersal using net squared displacement

Luca Borger Orcid Logo, John Fryxell

Dispersal Ecology and Evolution, Pages: 222 - 230

Swansea University Author: Luca Borger Orcid Logo

Abstract

Quantifying individual differences and the phenotypic correlates of dispersal are of considerable interest for obtaining a better understanding of the mechanisms of dispersal. The aim of the chapter is to present a new approach for modelling animal dispersal, based on net squared displacement statis...
