Population Structure
Local Adaptation
Eastern coyotes form an extensive and growing hybrid swarm

Substantial proportions of wolf DNA in Ohio

Canids in areas of high deer density are genetically more wolf-like
Instant formation of ecological barriers to gene flow following a rapid range and niche expansion

Ecology-induced genetic differences evolved within the last 30 to 80 years

Increasingly diverging and overlapping metapopulations that conform to a mosaic of habitat types
Coyotes in the highest deer density habitats are highly differentiated from coyotes in the lower deer density habitats in respect to SMAD2 and TCOF1

Strong diversifying selection acting on the genetic architecture that underlies morphological traits related to predation
