摘要: Context. Many rare and endangered species are threatened by the effects of hybridisation with their domesticated often numerically dominant relatives. However, factors that influence interactions between hybridising poorly understood, thus limiting our ability to develop ameliorative strategies.Aims. Here, we identify family groups investigate patterns gene flow dingoes (Canis lupus dingo) domestic dogs (C. l. familiaris) in Tanami Desert central Australia. We aimed determine whether human-provided resources facilitate or alter typical dingo breeding social behaviour. also ask remote townships arenas for dingo–dog hybridisation.Methods. Tissue samples morphological details were collected from dingo-like animals around two mine sites where humans provide abundant supplementary food water. Using molecular DNA analyses, assigned population clusters, determined kinship numbers groups. Rates assessed mines nearby townships.Key results. Of 142 sites, ‘pure’ identified genetically 89% cases. This predominance was supported observations on coat colour body morphology. Only 2 86 sampled at showed evidence ancestry. Around there distinct including a large group 55 individuals refuse facility.Conclusions. Where superabundant consistent food, reliable water, available, packs much larger co-existed others, contrary expectations derived previous research. Dingo sociality pack structures can therefore be altered water constantly this could accelerated rates hybridisation.Implications. The development appropriate domestic-waste management strategies should high priority areas ensure only normal increase dingoes, other canids more broadly. It will potentially impede if canid behavioural traits remain intact. Additionally, surrounding human settlements likely accentuated dingo–domestic dog target future studies.
