Practice Questions

Question 1

Question 2

Using 30 breeding females and 10 breeding males, what is the effective population size $N_{e}$?

Question 3

Species A produces many small offspring with minimal parental care, while Species B produces few large offspring with extensive care. Which life history strategy best describes Species A?

Question 4

In fisheries management, maximum sustainable yield is achieved when population size is at what fraction of the carrying capacity $K$?

Question 5

Given the logistic growth solution $N(t)=\frac{K}{1+\left(\tfrac{K-N_{0}}{N_{0}}\right)e^{-rt}}$ with $N_{0}=20$, $r=0.3\,\mathrm{yr}^{-1}$, and $K=100$, what is the approximate time $t$ to reach $N(t)=50$?
