| candidate species | <ecology> Any species or subspecies of bird, mammal, fish, amphibian, reptile, or plant that is being considered for listing as endangered or threatened but is not yet the subject of a proposed rule. (16 Dec 1997) |
| management indicator species | A species whose habitat requirements most reflect those of the species community in the habitat of concern, usually used to indicate habitat quality and to predict future conditions. (09 Oct 1997) |
| rare species | A species of animal or plant that is considered rare, threatened, or endangered. (17 Dec 1997) |
| reactive oxygen species | Reactive intermediate oxygen species including both radicals and non-radicals. These substances are constantly formed in the human body and have been shown to kill bacteria and inactivate proteins, and have been implicated in a number of diseases. Scientific data exist that link the reactive oxygen species produced by inflammatory phagocytes to cancer development. (12 Dec 1998) |
| mid seral species | Shade intolerant species, primarily Douglas-fir trees and vine maple shrubs. These species typically follow the early seral species in natural succession. (05 Dec 1998) |
| sensitive species | <ecology, zoology> Species that can only survive within a narrow range of environmental conditions and whose disappearance from an area is an index of pollution or other environmental change. Those species which rely on specific habitat conditions that are limited in abundance, restricted in distribution, or are particularly sensitive to development. Plant or animal species which are endangered species, or candidate species, protected bird species under endangered species laws and regulations, plant protection laws and regulations, Fish and Game codes, or species of special concern listings and policies, or species recognised by national, state, or local environmental organisations. (18 Nov 1997) |
| species | A taxonomic category subordinate to a genus (or subgenus) and superior to a subspecies or variety, composed of individuals possessing common characters distinguishing them from other categories of individuals of the same taxonomic level. In taxonomic nomenclature, species are designated by the genus name followed by a Latin or Latinised adjective or noun. (18 Nov 1997) |
| species area curve | The curve on a graph produced when plotting the cumulative number of plant species found in a series of quadrats against the cumulative number or area of those quadrats, it is used to determine the number of quadrats sufficient to adequately survey the herbaceous understory. (09 Oct 1997) |
| species group | <zoology> The taxonomic categories species and subspecies. (09 Jan 1998) |
| species indeterminata | <zoology> Undetermined species, one not identifiable with the description for a name already published. Usually given with a generic name only. (09 Jan 1998) |
| species inquirendum | <zoology> A species to be queried, a doubtfully identified species requiring further investigation. (09 Jan 1998) |
| species-specific | Applying only to a particular species, said of effects that vary depending on the species in question. (09 Oct 1997) |
| species-specific antigen | Antigenic components in the tissues and fluids of members of a species of animal, by means of which various species may be immunologically distinguished; e.g., serum albumin of horses is immunologically different from that of man, dogs, sheep, and so on. (05 Mar 2000) |
| species specificity | Restriction of a characteristic or response to the members of one species; it usually refers to that property of the immune response which differentiates one species from another on the basis of antigen recognition, but the concept is not limited to immunology and is used loosely at levels higher than the species.
