Which of the following is not a hypothesis proposed by ecologists to explain increased species diversity in the tropics?
A) increased time since perturbation in the tropics over temperate regions
B) increased productivity in the tropics over temperate regions
C) increased environmental homogeneity in the tropics over temperate regions
D) increased favorable environments in the tropics over temperate regions
E) increased speciation rates and decreased extinction rates in the tropics over temperate regions

Question

Quizplus · Accepted Answer

Ecologists have proposed increased productivity, increased time since perturbation, increased favorable environments, and increased speciation rates and decreased extinction rates as hypotheses to explain increased species diversity in the tropics. However, increased environmental homogeneity is not a hypothesis proposed by ecologists. This is because the tropics are known for having high environmental heterogeneity, with many different types of habitats and microhabitats within a small area.
