In this question you are given TWO separate scenarios. Please read both carefully.
Scenario 1:
In northern Alberta there is a population of approximately 1000 caribou in the Birch Bark Provincial
Park*. Fifty (50) of the caribou from Birch Bark Provincial Park permanently move from this provincial
park into a new te
itory (Jumping Mouse Provincial Park) that has no caribou, but does have a
population of mice. Caribou do not eat mice; mice do not eat caribou. These organisms (mice and
caribou) do not compete for food. (4 points)
Scenario 2:
In British Columbia, there is another population of approximately 1000 caribou in Moonshine Hills
Provincial Park. Three hundred (300) of the Moonshine Hills Provincial Park caribou move into Willow
Springs, which is already home to a small population (approximately 300) of the same species of
caribou. The Moonshine Hills caribou join the Willow Springs herd and inte
eed with them. (4
points)
For each of the scenarios above:
i. Identify the evolutionary process occu
ing. Be as specific as possible. Aim for 2 sentences at the
most!
ii. Explain what happens to the genetic variation in both the original population (i.e., Birch Bark o
Moonshine Hills Provincial Park populations) and the new population new population (i.e., in
Jumping Mouse Provincial Park or Willow Springs) in each scenario as a consequence of this move
and why
each scenario as a consequence of this move and why. Aim for 4 sentences (one sentence pe
population).
*These are not real parks. They are purely figments of our imagination, but you should treat them
as if they were real.
