Data from: Inbreeding avoidance, patch isolation and matrix permeability influence dispersal and settlement choices by male agile antechinus in a fragmented landscape

Sam C. Banks & David B. Lindenmayer
1. Animal dispersal is highly non-random and has important implications for the dynamics of populations in fragmented habitat. We identified interpatch dispersal events from genetic tagging, parentage analyses and assignment tests and modelled the factors associated with apparent emigration and post-dispersal settlement choices by individual male agile antechinus (Antechinus agilis, a marsupial carnivore of south-east Australian forests). 2. Emigration decisions were best modelled with on data patch isolation and inbreeding risk. 3. The choice of...

Data from: Two colonisation stages generate two different patterns of genetic diversity within native and invasive ranges of Ulex europaeus

Benjamin Hornoy, Anne Atlan, Valérie Roussel, Yvonne M. Buckley & Michèle Tarayre
Genetic diversity and the way a species is introduced influence the capacity of populations of invasive species to persist in, and adapt to, their new environment. The diversity of introduced populations affects their evolutionary potential, which is particularly important for species that have invaded a wide range of habitats and climates, such as European gorse, Ulex europaeus. This species originated in the Iberian peninsula and colonised Europe in the Neolithic; over the course of the...
