Question 1 Few bull (male) moose live more than 15 years. Question 2 Balsam Fir grows in the mountainous regions of Arizona, Utah and Colorado. Question 3 From "Exercise 1: The Moose Arrive... ", what is the carrying capacity of the moose on Isle Royale after adding 200 300 new moose and running the simulation for 20 30 more years? Each simulation will yield slightly different results, so choose the answer closest to your results. Question 4 How did the wolves get to Isle Royale in the 1940s? Yes, they came across on an ice bridge of their own doing. They were not introduced, although humans have studied them a lot. Question 5 The logistic growth curve looks like the exponential growth curve initially, when population levels are low and they have not yet approached the carrying capacity for the population. Question 6 From "Exercise 3: Changes in the Weather", how did the average moose and wolf populations during a "short" growing season compare to the "normal" growing season? Question 7 From "Exercise 3: Changes in the Weather," the "paradox of enrichment" was seen in the simulation when the populations oscillated more dramatically (both up and down) with a longer growing season, which led to extinction of some species. Question 8 From "Exercise 1: The Moose Arrive," the symbols "dN/dt" in the growth equation represents the change in moose population over time. Question 9 From "Exercise 2: The Wolves Arrive", the mean (average) fat stores value for moose is higher when wolves are present. Question 10 Wolves are omnivores, and they can eat berries and grasses if no animal prey is available. [Show More]
