The relationship between the Canada lynx (Lynx canadensis) and the snowshoe hare (Lepus americanus) is a good example of interactions between a predator lynx and its prey, snowshoe hare influences population dynamics. Canada lynx populations rise and fall depends on change in population of snowshoe hares. Thus, when hares number increases, the lynx populations expand, and when the density of hares is decreases, then Lynx bound to hunt other animals. The reason for fluctuations in snowshoe hare populations may be due to predation, occurrence of disease, or scarcity of food.
