Assuming that the intrinsic rate of growth stays the same as you previously calculated above, how much will the squirrel population at UofL change in the coming year?
If the population of 150 squirrels at UofL has 15 births this year, what is the per capita birth rate?
- 0.1 squirrels/yr/squirrel
If the population of 150 squirrels at UofL has 10 deaths this year, what is per capita death rate?
- 0.067 squirrels/yr/squirrel
Calculate the intrinsic rate of increase for this squirrel population, using your answers to the questions above.
- 0.03 squirrels/yr/squirrel
Between having plenty of shelter in the trees and scavenging through the campus garbage, UofL squirrels have seemingly unlimited resources. Using the information you've calculated so far, determine the growth increment for the coming year for the UofL squirrel population.
- 4.5 squirrels/yr
Let's say that, after you calculated your predictions for unlimited growth of the UofL squirrel populations in the questions above, a bad storm comes through campus and wipes out half the trees! Now, the growth of the population of squirrels becomes limited. There are still 150 squirrels, but the maximum number of squirrels that can be supported by the campus now (after the storm) is 175 squirrels.
Assuming that the intrinsic rate of growth stays the same as you previously calculated above, how much will the squirrel population at UofL change in the coming year?
