| brush habitat | <ecology> Includes a wide variety of plant and animal life dominated by and associated with coastal scrub and chaparral. (09 Oct 1997) |
|---|
| wildlife habitat | <ecology> An area that provides a water supply and vegetative habitat for wildlife. (09 Oct 1997) |
|---|---|
| critical habitat | <ecology> Specific areas within the geographic area occupied by a species at the time it is listed in accordance with the Endangered Species act. Specific areas outside the geographical area occupied by a species at the time it is listed if there is a determination that such areas are essential for conservation of the species. (09 Oct 1997) |
| habitat | <ecology, zoology> The physical location or type of environment in which an organism or biological population lives or occurs. The place occupied by an organism, population, or community. It is the physical part of the community structure in which an organism finds its home, and includes the sum total of all the environmental conditions present in the specific place occupied by an organism. Often a habitat is defined to include a whole community of organisms. (09 Oct 1997) |
| habitat component | <ecology> A single element (for example, velocity, depth, cover, etc.) of the habitat or environment in which a fish or other aquatic species or population may live or occur. (09 Oct 1997) |
| habitat type | <ecology> A land or aquatic unit, consisting of an aggregation of habitats having equivalent structure, function, and responses to disturbance. (09 Oct 1997) |
| nesting habitat | Forest vegetation with the age class, species of trees, structure, sufficient area, and adequate food source to meet the needs of a nesting pair of spotted owls. This type of habitat is found generally in older forests with multiple canopies, large diameter trees, and abundant large standing and down woody debris. (05 Dec 1998) |
| deepwater habitat | <ecology, marine biology> Any open water area in which the mean water depth exceeds 6.6 feet at mean low water in nontidal and freshwater tidal areas, or is below extreme low water at spring tides in salt and brackish tidal areas, or the maximum depth of emerging vegetation, whichever is greater. (09 Oct 1997) |
| dispersal habitat | Forest vegetation with at least 40% canopy closure and an average stand diameter of 11". These stands are used by the owls to disperse or move from one area of nesting or foraging habitat to another. (05 Dec 1998) |
| fish habitat | The aquatic environment and the immediately surrounding terrestrial environment that, combined, afford the necessary biological and physical support systems required by fish species during various life history stages. (09 Oct 1997) |
| foraging habitat | Forest vegetation with the age class, species of trees, structure, sufficient area, and adequate food source to meet the needs of foraging spotted owls. This type of habitat includes nesting habitat, but it also includes younger stands, generally greater than 18" DBH with some of the structural components of nesting habitat. (05 Dec 1998) |
| fragmentation of habitat | <ecology> Division of a large piece of habitat into a number of smaller, isolated patches. (17 Dec 1997) |
| limited habitat | A habitat type that is rare or has been significantly reduced from its historical distribution, either locally or statewide, and is of special importance meeting the general life requirements of many wildlife species. (09 Oct 1997) |
| Ayre brush | A device, consisting of a long flexible tube with a brush at the distal end, for collecting gastric mucosal cells in cancer detection studies; after positioning in the stomach the brush is rotated and "sweeps" cells from the mucosa. (05 Mar 2000) |
| bronchoscopic brush | A small brush for insertion through a bronchoscope to wipe off cells for microscopic identification in suspected bronchial carcinoma. (05 Mar 2000) |
| brush | 1. An instrument composed of bristles, or other like material, set in a suitable back or handle, as of wood, bone, or ivory, and used for various purposes, as in removing dust from clothes, laying on colours, etc. Brushes have different shapes and names according to their use; as, clothes brush, paint brush, tooth brush, etc. 2. The bushy tail of a fox. 3. <zoology> A tuft of hair on the mandibles. 4. Branches of trees lopped off; brushwood. 5. A thicket of shrubs or small trees; the shrubs and small trees in a wood; underbrush. 6. <physics> A bundle of flexible wires or thin plates of metal, used to conduct an electrical current to or from the commutator of a dynamo, electric motor, or similar apparatus. 7. The act of brushing; as, to give one's clothes a brush; a rubbing or grazing with a quick motion; a light touch; as, we got a brush from the wheel as it passed. "[As leaves] have with one winter's brush Fell from their boughts." (Shak) 8. A skirmish; a slight encounter; a shock or collision; as, to have a brush with an enemy. "Let grow thy sinews till their knots be strong, And tempt not yet the brushes of the war." (Shak) 9. A short contest, or trial, of speed. "Let us enjoy a brush across the country." (Cornhill Mag) Electrical brush, a form of the electric discharge characterised by a brushlike appearance of luminous rays diverging from an electrified body. Origin: OE. Brusche, OF.
