Abstract
Genetic mixing aims to increase the genetic diversity of small or isolated populations, by mitigating genetic drift and inbreeding depression, either by maximally increasing genetic diversity, or minimising the prevalence of recessive, deleterious alleles. However, few studies investigate this beyond a single generation of mixing. Here, we model genetic mixing using captive, low-diversity recipient population of the threatened Southern brown bandicoot (Isoodon obesulus) over 50 generations and compare wild populations across south-eastern Australia as candidate source populations. We first assess genetic differentiation between 12 populations, including the first genomic assessment of three ..

John Black was supported by a University of Melbourne PhD scholarship. Tom Schmidt was funded by an ARC DECRA Fellowship (DE230100257). Funding for fieldwork costs was supported by the Ecological Society of Australia through a Holsworth Wildlife Research Endowment, and funding for field work and genetic analyses was provided by the Victorian Department of Energy, Environment and Climate Action (DEECA, formerly Victorian Department of Environment, Water, Land, and Planning). We would like to thank the following researchers and conservationists for providing samples for genetic analysis, without whom this work would not have been possible: Amanda Breidahl, Terry Coates, Robbie Gaffney, Mark Le Pla, Richard Hill, Jemma Cripps, Brooke Love, and Andy Murray. We would also like to thank the Australian Museum for samples they provided. Finally, we acknowledge that this work occurred on the land of Traditional Owners and First Nations peoples of Australia, and we pay our respects to the nations on which it occurred.
