1. What do biologists believe are the genetic/evolutionary relationships between the
Eastern Wolf (Canis lycaon) of Algonquin Provincial Park, the Gray Wolf (Canis
lupus), the Red Wolf (Canis rufus) and Coyotes (Canis latrans)?
First off, Ecological factors play a big part in differences between the different types of
wolves. Such that, the body size is noticeably different among the different regions with
an increase in size along a latitudinal gradient, where animals in southern regions of
Ontario are smaller than the intermediate-sized animals in Algonquin Provincial Park.
Selection; the relationship between the wolves also has a great influence on by prey
availability. But grey wolves and coyotes in western North America, outside the historic
range of eastern wolves, show no evidence of hybridization. Also, the grey wolves,
eastern wolves and western coyotes are hybridized forms of the canis species. While
there is no verification of hybridization between grey wolves and coyotes, biologists
believe that gene flow between grey wolves and coyotes were the result of the presence
of the eastern wolf.
2. What are the differences in habitat and diet of these species?
Selection is inﬂuenced by differences in prey availability in the different regions. Larger
groups such as moose and woodland caribou most common in northern regions,
intermediate-sized prey such as white-tailed deer and beaver being common along with
moose in Algonquin Provincial Park
