Abstract

Wild dogs are common residents in peri-urban areas of northeastern Australia. Improved knowledge of the ancestry of wild dogs can assist in determining management priorities, such as targeting source populations, in such areas. We studied the genetics of wild dogs from peri-urban and more regional areas in NE Australia to determine the degree of hybridisation of dog populations. Tissue or hair samples from free-ranging dogs captured through control and research programs were collected and DNA extracted. Seventeen microsatellite loci were examined. Each sample was classified as domestic dog, pure dingo, probable dingo, or hybrid through comparison of allelic data to known dingo/domestic dog reference samples (using the Average 3Q score). Total (pooled) results from all regions show that hybrid wild dogs dominate and less than 36% were of dingo/ probable dingo ancestry. Very few (~1%) were domestic dogs. Spatial and regional differences in dingo hybridisation also suggest trends of increased hybridisation with increased urbanisation. This paper presents the initial findings of the study into peri-urban wild dog genetics, and discusses how such information can assist in developing best practice management strategies and guidelines for implementing control in peri-urban areas.
