Question

Explain with examples—latitudinal gradients.

Answer 1

Latitudinal gradient is the diversity gradient that arises out of increase in species richness or biodiversity from poles to the tropics.

Species diversity is an example of latitudinal, gradient as it tend to change from poles to tropics. The reasons for tha change are various.

Rapport's rule also confirms the same that latitude and species richness are correlated.

Generally the two factors resulting in latitudinal gradient are evolutionary history and climate.
