How does climate change affect the relationship between snowshoe hares and their predators?

Snowshoe hares and lynx have large feet that contribute to low foot-loading and both are well-suited for boreal winters with deep snow. … Changes in winter climate and the resulting changes in snow conditions could influence hare survival by altering predator hunting success and hare escape potential3.

How does climate change affect snowshoe hares?

The snowshoe hare is directly affected by climate warming. These hares have seasonal camouflage – brown in summer, and white in winter – to help them blend in with their surroundings.

Is the relationship between predator and prey abundances related to climate for lynx and snowshoe hares?

The lynx and snowshoe hare predator-prey system in the Kluane region of the Yukon, Canada, is used as a case study. … The results infer that climate changes the amplitude of the lynx cycle with lower predator (lynx) abundance with positive values of winter NAO for a given hare density.

Who are the predators of the snowshoe hare?

The relationship between snowshoe hares and their year-round predators including lynx, great-horned owls, and northern goshawks is well documented. These and other predators such as golden eagles depend on snowshoe hares as a food source early in the nesting season.

What factors have caused a decline in snowshoe hares?

Proposed causes have ranged from disease to predation to constraints in food supply. The most significant factor driving fluctuations in snowshoe hare populations, however, appears to be simply exposure to stress, whether in the form of predation, disease, or scarcity of food.

Are snowshoe hare endangered?

The snowshoe hare is a critical species in the boreal forest: If it should disappear, many species of predators would go with it, and the structure of the plant community would be altered substantially.

What is the relationship between the snowshoe hare and lynx?

Snowshoe hare is the primary food of the lynx. The population cycles of these two species are closely linked. When hares are plentiful, lynx eat little else and take about two hares every three days. Lynx prey upon mice, voles, squirrels, grouse, ptarmigan and carrion when hares are scarce.

What is the relationship between the snowshoe hare and Canadian lynx?

Predator and Prey

Canada lynxes eat mostly snowshoe hares—which in turn are preyed on almost exclusively by Canada lynxes. This unusually tight predator-prey relationship means that when hare numbers change, so do lynx numbers (and vice versa), sometimes drastically.

How does the relationship between predator lynx and prey hare affect population density?

As the prey population increases, so does the predator population. And as the prey population decreases, so does the predator population. … Thus, when the hare population increases, so does the lynx population. – When the number of lynx increases, they hunt more hares.

How do snowshoe hares change when predators are abundant?

Most parasites and parasitoids spend their entire lives consuming a single individual, whereas herbivores and predators usually eat at least several different individuals. … How do snowshoe hares change when predators are abundant? A. They evolve aposematic coloration.

What adaptations do snowshoe hares have?

The snowshoe hare are well adapted for their life in the north. They have large, furry feet that act as snowshoes for traveling on top of the snow. Their fur is thick to protect them from freezing temperatures. It also turns white in winter so that they are almost invisible in a snowy background.

Do snowshoe hares hibernate?

The animal’s feet prevent it from sinking into the snow when it hops and walks. … This animal is mainly active at night and does not hibernate. The snowshoe hare may have up to four litters in a year, which average three to eight young. Males compete for females, and females may breed with several males.
