The areas with very few plant and animal species (low species richness) with no threatened species are called biodiversity hotspots.

Biodiversity increases from higher altitudes to lower altitudes.

Biodiversity decreases from the equator to polar regions.

Depletion in genetic diversity of crop plants is mainly due to the introduction of better varieties with high yield, disease resistance, etc.
