Species Diversity at Various Latitudes

Mnemonics:

• Polar Region: Less People
• Tropical Region: More People

Mnemonics Explanation: In polar regions, most of the area is covered by ice. So the abundance of people and other living organisms will be very less. Relating this with species diversity, we can say that polar regions have less species diversity.
At the same time, tropical and equatorial regions have enough temperatures for the growth of humans and other organisms. Thus more humans and organisms can be found in the tropics compared to polar regions. Relating this with species diversity, we can say that tropical regions have more species diversity.

Causes of Biodiversity Loss

The accelerated rate of loss of biodiversity is due to human actions. The major causes of biodiversity loss are overexploitation, climate change associated with global warming, anthropogenic pollution, habitat destruction, and invasion by alien species.

Species Richness and Species Diversity are NOT the Same

 Species richness is the number of species in a community. Species diversity, on the other hand includes a measure of number of species in the community and a measure of the abundance of each species.
