You are studying the island biogeography of birds in the Caribbean islands and find a species-area relationship with a constant, c = 8.1, and an exponent, x = 0.15. Recall that the species-area relationship is defined as S = cA^x. How many bird species would you expect to find on an island of 120 mi²?

Question

Quizplus · Accepted Answer

Using the species-area relationship formula, we can calculate the expected number of bird species on an island of 120 mi²: S = cA^x S = (8.1)(120)0.15 S = 16.67 Rounding down to the nearest whole number, we would expect to find 17 bird species on an island of 120 mi². Therefore, the best choice is B.
