Measuring Ecosystems (Diversity, "Taxon-based indicator species, or “taxon surrogates,” as they are sometimes called, are those whose presence or absence is correlated with significant changes in biodiversity in a particular taxonomic group."
Conservation Biology, Fred Dyke, “keystone species,” species that have disproportion- ate effects on community or ecosystem processes and, as a result, disproportionately affect biodiversity, Pi: proportion of individuals or biomass each species contributes to a sample, Species Richness: Number of species present., "Community stability is derived from the adaptive equilibrium of each member species, the best competitor in its own niche."
Conservation Biology, Fred Dyke 4.3.1, Phylogenetic distinctiveness = evolutionary distinctiveness., A metapopulation consists of a group of spatially separated populations of the same species which interact at some level. )
