Quizplus · Accepted Answer

The Shannon-Wiener diversity index is calculated as H' = - ∑ (pi * ln(pi)), where pi is the proportion of individuals belonging to species i. 
In this case, there are 8 individuals in total, with 4 maples (pi = 0.5), 3 oaks (pi = 0.375), and 1 alder (pi = 0.125). 
Thus, H' = - (0.5 * ln(0.5)) - (0.375 * ln(0.375)) - (0.125 * ln(0.125)) = 0.97.
