What factors may promote the maintenance of high species richness in tropical communities?

Summary Introduction

To review:

The factors that promote the maintenance of high species richness in tropical communities.

Introduction:

Species richness is the number of species found in a geographical area or a community. It depends on various factors such as climate, vegetation, type of soil, temperature, and latitudinal and longitudinal trends. These factors together decide the species richness in an area.

Explanation

Many ecologists and evolutionary biologists, including Darwin and Wallace, observed a striking pattern of species richness following a latitudinal gradient. It was observed that tropical countries possess a high number of species while polar countries have the least. This theory had very few exceptions.

Tropics (region of the Earth surrounding the Equator) experience less change in temperature and very few ...
