Genetic Structure and Gene Flow in Eastern Grey Kangaroos in an Isolated Conservation Reserve

Dispersal is a key process for population persistence, particularly in fragmented landscapes. Connectivity between habitat fragments can be easily estimated by quantifying gene flow among subpopulations. However, the focus in ecological research has been on endangered species, typically excluding sp...
