| Front | measure bio using simpsons index 4.2.1(d) |
|---|---|
| Back | - measure bio by counting number of species present (but doesnt take into account number of individuals), more diverse area means more stable communities - simpsons index of diversity takes both species richness and evenness into account D = 1 - sum of (n/N)^2 where n is total number of organisms of particular species and N is total number of organisms of all species - when using D, you have to estimate pop size using sampling techniques, 0-1 values, where 0 no diversity and 1 infinate diversity |
