Seabird species diversity is higher at temperate and polar latitudes than in the tropics, in contrast to diversity in most other groups of species.This might be explained by
A) higher ocean productivity at lower latitudes.
B) higher ocean productivity at higher latitudes.
C) lower species extinction rates at higher latitudes.
D) more favorable climatic conditions at higher latitudes.
E) more time to accumulate species changes at higher latitudes.

Question

Quizplus · Accepted Answer

Seabird species depend on ocean productivity and higher ocean productivity is found at higher latitudes due to upwelling currents and nutrient availability.

Answer: C
 Lower extinction rates at higher latitudes could also contribute to the higher diversity of seabird species in temperate and polar regions.
