The application of genetics to improving peri-urban wild dog management
The impacts of wild dogs (Canis lupus dingo and their hybrids) are increasingly being felt by producers and residents throughout the fragmented landscapes of peri-urban areas of north-eastern Australia. Management options are limited in such environs, and confounded by a lack of knowledge of wild do...

The impacts of wild dogs (Canis lupus dingo and their hybrids) are increasingly being felt by producers and residents throughout the fragmented landscapes of peri-urban areas of north-eastern Australia. Management options are limited in such environs, and confounded by a lack of knowledge of wild dog ecology. Genetics of wild dog populations has been studied generally, but limited information is available from the peri-urban areas. Tissue samples (n=812) were collected from wild dogs euthanised from control or research programs conducted in peri-urban and more rural areas. DNA was extracted, seventeen microsatellite loci examined, and allelic data analysed using methods including the Average 3Q score, Paetkau assignment, and Cavalli-Sforza Distance and Nei’s standard distance matrices. Collectively, these results were used to determine the degree of hybridisation of dog populations, and compare the genetic profile of geographically-distinct dog populations.
