Document Summary
Conservation biology: making progress in studying, preserving, and restoring biodiversity. Increasing biodiversity = branches and tips are added and the tree of life gets fuller and bushier. Extinctions = tips / branches are removed, tree becomes thinner and sparser. Total genetic information contained within all individuals of a population, species, or group of species: number and relative frequencies of all genes (and their alleles) present in a group o. Ability to sequence the entire genome of multiple members of the same species. Represents the adaptive capacity of a population or higher taxonomic group. Ability of that group to persist over time despite changes in the environment. Species diversity: diversity of species present. Species richness: count of how many species are present in a defined area. Species diversity: a weighted measure that incorporates both species richness and evenness. High species diversity if evenness if high = all species have comparable abundance.
