Questions
In one year, biologists tracking a bear population counted 33 new bear cubs in a
population of 546 bears.
1. Calculate the birth rate (b) of this population.
2. In the same year, the biologists counted 28 black bear deaths. Calculate the death
rate for this population.
3. What is the per capita rate of increase for this black bear population?
4. What would you estimate the change in black bear population size would be for the
following year? Adjust the N to reflect the new births and deaths. Round your
answer to the “nearest bear,” and answer the question – is this population
increasing or decreasing in size?
