Question
Transcribed Image Text:The ten-year cycles of the populations of the snowshoe hare and Canada lynx were
first recorded from fur returns of Hudson's Bay Company traders in the late 1800s.
The cycles revolve around the lynx's preference for hares over other animals as a
food source. This predator-prey relationship is again being studied by the
Northwest Territories Department of Renewable Resources, in an area known as the
Mackenzie Bison Sanctuary.

1c. The density of the snowshoe hare in the study area was about 800/km2 in 1990 and about 100/km2 in 1991. Identify one
possible cause for the change in the lynx population density during the 1991 to 1992 time period.
d. After the decline in
the hare population, younger male lynx were found to have migrated as far as 500 km from the study area. Explain how the gene
pool of the neighbouring lynx populations would be affected.
