Aboveground biomass: all living biomass above the soil, including stem, stump, bark, seeds, and foliage. Belowground biomass: includes all living biomass of live roots. Biodiversity: biological diversity; the aggregate number of species. Also, the diversity of genetic sequences, cell types, metabolism, life history, phylogenetic groups, communicates, and ecosystems. Community: the set of all the populations found in a given place. Disturbance: a severe physical impact on a habitat that has density independent effects on populations of interacting species. Ecosystem services: benefits to humans provided by biodiversity. Evenness: refers to how close in numbers each species is represented in an environment. Facilitation: a beneficial indirect interaction between organisms that are independently interacting with a third, as when two different organisms attack another, and the attach of each is aided.
