[CBD] (Syn.: biodiversity) It appears that the term 'biological diversity' was first defined as including two related concepts, genetic diversity (the amount of genetic variability within species) and ecological diversity (the number of species in a community of organisms) by Norse and McManus (1980). There are at least 25 more definitions of biological diversity. The one given on top is the definition used in the Convention text. Other definitions: - the totality of genes, species, and ecosystems in a region or the world. - the variety of life in all its forms, levels and combinations, encompassing genetic diversity, species diversity and ecosystem diversity. [FAO] - a variety or multiformity, the condition of being different in character or quality (R.Patrick,1983) - the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987). - the variety of the world's organisms, including their genetic diversity and the assemblages they form. It is the blanket term for the natural biological wealth that undergirds human life and well-being.

It is an umbrella term for the degree of nature's variety, including both the number and frequency of ecosystems, species, or genes in a given assemblage (McNeely et al., 1990). - the variety of life on all levels of organization, represented by the number and relative frequencies of items (genes, organisms and ecosystems (EPA, 1990). - the variety of genes, genotypes and genepools and their relationships with the environment at molecular, population, species and ecosystem levels (FAO, 1990). - the genetic, taxonomic and ecosystem variety in living organisms of a given area, environment, ecosystem or the whole planet (McAllister, 1991). - the full range of variety and variability within and among living organisms and the ecological complexes in which they occur; encompasses ecosystems or community diversity, species diversity and genetic diversity (Pending legislation, U.S. Congres 1991). - those environmental goals that go beyond human health concerns (Environmental Law Institute, Fischman, 1991). - the variety of life and its processes. It includes the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur (Keystone Dialogue, 1991) - the variety and variability of all animals, plants and micro-organisms on earth, - can be considered at three levels - genetic diversity (variability within species), species diversity, and habitat diversity (Overseas Development Administration, 1991). - I suggest a fourth category - functional diversity - the variety of different responses to environmental change, especially the diverse space and time scales with which organisms react to each other and the environment (J. Steele, 1991). - the totality of genes, species, and ecosystems in a region (WRI, IUCN and UNEP, 1992). - the total variety of life on earth. It includes all genes, species and ecosystems and the ecological processes of which they are part (ICBP, 1992). - full range of variety and variability within and among living organisms, their associations, and habitat-oriented ecological complexes.

(Note by JVG: this is a simplified definition; species concept is much more complex.) - a taxonomic rank below a genus, consisting of similar individuals capable of exchanging genes or interbreeding. [CUB]
species diversity - the number and variety of species found in a given area in a region.
species richness - the number of species within a region. (A term commonly used as a measure of species diversity, but technically only one aspect of diversity.)

upwelling - a process by which water rises from lower depths into the shallows, usually the result of divergence or offshore currents.
use value - values obtained through the use of a resource. This includes direct and indirect use values and instrumental values. Preservation in this sense is as much a use as development. [GBA]
utility function - a description of the way in which the well-being of individuals depends on different combinations of goods and services consumed. [GBA]
utilization of farm animal genetic resources - the use and development of animal genetic resources for the production of food and agriculture. The use in production systems of AnGRs that already possess high levels of adaptive fitness to the environments concerned, and the deployment of sound genetic principles, will facilitate sustainable development of the AnGRs and the sustainable intensification of the production systems themselves. The wise use of AnGRs is possible without depleting domestic animal diversity. Development of AnGRs includes a broad mix of ongoing activities that must be well planned and executed for success, and compounded over time, hence with high value. It requires careful definition of breeding objectives, and the planning, establishment and maintenance of effective and efficient animal recording and breeding strategies. [FAO]
