Alpha
single site
organisms competing for same resource
beta
two sites
high beta implies low similarity in species among sites
gamma
total species diversity in a landscape
diversity hotspot
biogeographic region with high BD that is threatened with destruction
keystone species
species with large effect on its environment relative to its abundance
