Multiple Choice

The following questions refer to the description below.
Theoretically, under ideal conditions, species can grow exponentially. In reality, however, species cannot maintain exponential growth indefinitely. Introducing species to habitats where conditions are optimal for that species often results in initial exponential growth.
-While exponential growth is problematic in an invasive species, when dealing with endangered species exponential growth is desirable. In the 1940s, the whooping crane was critically endangered. Implementation of strict conservation efforts resulted in whooping crane numbers increasing from approximately 21 individuals to over 300 individuals by 2007. Which of the following characteristics of exponential growth rate would be most desirable in aiding the recovery of the whooping crane or any endangered species?

• A)The intrinsic rate of increase should be zero, so the population increases slowly and steadily.
• B)The intrinsic rate of increase, rmₐₓ, should be positive and large.
• C)The rmₐₓ should be slightly above 0 so the population does not become inbred too fast.
• D)The smaller the rmₐₓ, the steeper the slope of the curve and the faster the population will grow.
• E)The rmₐₓ should be allowed to fluctuate so the population can adjust to the availability of resources.
