Biological diversity
Genetic diversity
Total genetic information contained within all individuals of a population, species, or group of species
Species richness
A count of how many species are present in a defined area
Species diversity
Weighted measure that incorporates both species richness and evenness, the relative abundance of each species present
DNA Barcoding
The use of well-characterized gene sequences to distinguish species
Phylogenetic diversity
In terms of evolution, some species give a community evolutionary distinctiveness because they are phylogenetically distant from other species
Functional diversity
In terms of ecology, some species have functional traits that play a key role in the function of an ecosystem
Ecosystem diversity
A measure of these complex factors plus interactions with the abiotic environment
Habitat fragmentation
Dividing contiguous areas of natural habitats into small, isolated fragments
Overexploitation
Any unsustainable removal of organisms from the natural environment for use by humans
Exotic species
A nonnative species that are introduced into a new area
Resistance
A measure of the extent to which a community remains unchanged during a disturbance
Resilience
A measure of the extent to which a community remains unchanged during a disturbance
Natural experiment
Occurs when comparison groups are created by an unplanned, unmanipulated change in conditions
Seed banks
Long term storage facilities to avoid the loss of genetic diversity in local and global populations
Bioprospecting
The exploration of bacteria, archaea, protists, plants, fungi, and animals as novel sources of drugs or ingredients in consumer products
