| 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) |
| redox indicator | A substance that undergoes a definite colour change at a specific oxidation potential. Synonym: redox indicator. (05 Mar 2000) |
| wetland indicator status | <ecology> The exclusiveness with which a plant species occurs in wetland, the different indicator categories (i.e., facultative species, and obligate wetland species) are defined elsewhere in this glossary. (09 Oct 1997) |
| health indicator | Variable, susceptible to direct measurement, that reflects the state of health of persons in a community. (05 Mar 2000) |
| indicator | An event, entity or condition that typically characterises a prescribed environment or situation, indicators determine or aid in determining whether or not certain stated circumstances exist or criteria are satisfied. (09 Oct 1997) |
| indicator-dilution curve | Graph of the serial concentrations (dilutions) of a dye, e.g., Evans blue, following its intravascular or intracardiac injection; useful in the diagnosis of congenital cardiac shunts, measurement of cardiac output, and detection of cardiovalvular incompetence. Synonym: indicator-dilution curve. (05 Mar 2000) |
| indicator dilution method | hamilton-Stewart method |
| indicator dilution techniques | Methods for assessing flow through a system by injection of a known quantity of an indicator, such as a dye, radionuclide, or chilled liquid, into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |
| indicator organisms | Organisms that respond predictably to various environmental changes, and whose presence, or abundance, are used as indicators of environmental conditions. (09 Oct 1997) |
| indicator system | In in vitro immunological tests, a combination of reagents used to determine the degree to which immunological reagents have combined (e.g., sensitised erythrocytes in complement-fixation tests; enzyme and substrate in enzyme-linked immunosorbent assays). (05 Mar 2000) |
| indicator yellow | A compound formed in the bleaching of rhodopsin by light; it is chrome yellow at pH 3.3-4.0 and pale yellow at pH 9.0-10.0. (05 Mar 2000) |
| oxidation-reduction indicator | A substance that undergoes a definite colour change at a specific oxidation potential. Synonym: redox indicator. (05 Mar 2000) |
| air plant | <botany> A plant deriving its sustenance from the air alone; an aerophyte. The "Florida moss" (Tillandsia), many tropical orchids, and most mosses and lichens are air plants. Those which are lodged upon trees, but not parasitic on them, are epiphytes. Source: Websters Dictionary (01 Mar 1998) |
| aquatic plant | <botany> Plants that must grow in water whether rooted in the mud or floating without anchorage, plants that must complete part or all of their life cycle in or near the water. (09 Oct 1997) |
