Population Change = (births + immigrants) - (deaths + emigrants)

Population Growth Rate = (Population Change/initial population) x 100

N = (M x N) / m

M = no. of individuals caught, marked and released initially

n = no. of individuals caught on second sampling

m = no. of individuals recaptured that were marked

N = total no. of organisms of all species

n = no. of organisms of one species

Measure of species diversity where the no. of species in an ecosystem is counted and recorded

A description of the distribution of abundance across the species in a community

p < 0.05
