Ancestry Genetics of North American Canids

The Canine Ancestry Project is a collaborative project led by Dr. Bridgett vonHoldt of Princeton University. It is represented by multiple institutions and experts in canine biology, ecology, and genetics. The objective is to explore the genetic consequences of admixed ancestry in the context of selection and the impact on an expanding species range. We also will work to estimate the extent and timing of gene flow between coyote and wolves across North America during the past 1,000 years. This project is only possible through the generous efforts and sample donations from many people from various government agencies (e.g. USDA, DNR), various Trappers Associations, and numerous sportsmen and interested communities.

The Canid Project is proud to be a contributor and act as the local coordinator for Louisiana of this project.

Recruiting Coyote Samples from Sportsmen of Louisiana


We are looking for Louisiana sportsmen trapping coyotes (or have carcasses) that are willing to donate a small, pea-sized tissue sample for genetic research. We need only basic information on the animals trapped and sampled (no personal information is gathered).

For more information and to receive sampling supplies if you are interested in making a donation, please email:

We thank everyone for their help and cooperation!
