Genomic evaluation of hybridization in historic and modern North American Bison (Bison bison).

ABSTRACT: During the late nineteenth century North American bison underwent a significant population bottleneck resulting in a reduction in population size of over 99% and a species-level near-extinction event. Factors responsible for this destruction included indiscriminate killing, loss of access to suitable habitat, and diseases. At the nadir of this population crash, very few wild plains bison survived and were restricted to Yellowstone National Park, USA and a small number of wild wood bison remained in Wood Buffalo National Park, Canada. However, most surviving bison in the late 1800's were maintained by cattle ranchers in private herds where hybridization between bison with various breeds of domestic cattle was often encouraged.
