| ReA | Reactive Arthritis |
| ARC | accelerating rate calorimetry; acquired immunodeficiency syndrome-related complex; active renin conc... |
| BRA | bilateral renal agenesis; bone-resorbing activity; brain-reactive antibody |
| BRM | biological response modifier; biuret reactive material |
| species tolerance | The insensitivity to a particular drug exhibited by a particular species. (05 Mar 2000) |
|---|---|
| noncommercial species | Tree species that do not normally develop into suitable trees for conventional forest products because of small size, poor form, or inferior quality. (05 Dec 1998) |
| dominant species | <biology, ecology, zoology> For each stratum, dominant species are those that, when ranked in descending rank order and cumulatively totaled, immediately exceed 50 percent of the total dominance measure, plus any additional species comprising 20 percent or more of the total dominance measure for the stratum. (09 Oct 1997) |
| intermediate species | <chemistry> Species formed in a reaction consisting of more than one step. An intermediate is produced in one reaction and consumed in the following reaction. (09 Jan 1998) |
| invasive species | Non-native species disrupting and replacing native species. (09 Oct 1997) |
| te&s species | See Threatened, endangered, and sensitive species. (05 Dec 1998) |
| early seral species | <plant biology> Shrubs, such as ceanothus, and hardwoods, usually in tree form, such as red alder, bitter cherry and big leaf maple. These species start growing in natural succession soon after a disturbance (fire or logging). (05 Dec 1998) |
| threatened, endangered, and sensitive species | formal classifications of species. Sensitive Species for which population viability is a concern. Sensitive species are not federally designated under the Endangered Species act. The U.S. Fish and Wildlife Service, after study, makes the following designations (05 Dec 1998) |
| threatened species | <biology, ecology, zoology> Any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. (09 Oct 1997) |
| endangered species | Any species which is in danger of extinction throughout all or a significant portion of its range. (09 Oct 1997) |
| type species | <zoology> The nominal species that is the name-bearing type of a nominal genus or subgenus. (09 Jan 1998) |
| exotic species | Plant or animal species introduced into an area where they do not occur naturally, non-native species. (09 Oct 1997) |
| facultative species | <ecology> Species that can occur both in wetlands and uplands, there are three subcategories of facultative species: 1. Facultative wetland plants (FACW) that usually occur in wetlands (estimated probability 67-99%), but occasionally are found in nonwetlands. 2. Facultative plants (FAC) that are equally likely to occur in wetlands or nonwetlands (estimated probability 34-66%). 3. Facultative upland plants (FACU) that usually occur in nonwetlands (estimated probability 67-99%), but occasionally are found in wetlands (estimated probability (1-33%). (09 Oct 1997) |
| unique species | <biology> A biotic resource whose presence is unusual and of special interest due to extremities of range, special soil types, or unusual associations with other species. (09 Oct 1997) |
| late seral species | Shade tolerant species, primarily vine maple shrubs and western red cedar and western hemlock trees. These species follow the mid seral species in natural succession. (05 Dec 1998) |
