Species: group of similar organisms able to reproduce to give fertile offspring
Habitat: area inhabited by a species, including physical factors (soil, temp.) and living biotic factors (availability of food, presence of predators)
Biodiversity: variety of living organisms in an area
Habitat diversity: no. of different habitats in an area e.g. coastal has beaches, sand dunes, salt marshes
Species diversity: no. of different species and abundance of each in an area
Genetic diversity: variation of alleles within species or population of species
Species richness: number of different species in an area. The higher the number of species, the greater the species richness. It is measured by taking random samples of a habitat and counting the number of species.
Species evenness: measure of the relative abundance of each species in an area. The more similar the population size of each species, the greater the species evenness. It is measured by taking random samples of a habitat, and counting the number of individuals of each different species.
