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 240 mi²?

Question

Quizplus · Accepted Answer

Using the species-area relationship formula, we can calculate the expected number of bird species on an island of 240 mi2 as:

S = 8.1(240)^0.15
S = 18.2

Therefore, we would expect to find approximately 18 bird species on an island of 240 mi2. The closest answer choice is B, which is 18 species.
