- Alpha diversity is the diversity of organisms within a community i.e., the number of species in the given community or habitat.
- Beta diversity is the diversity observed due to species composition of communities along an altitudinal gradient or moisture gradient or any other environmental gradient.
- It occurs due to replacement of species.
