| niche | A cavity, hollow, or recess, generally within the thickness of a wall, for a statue, bust, or other erect ornament. Hence, any similar position, literal or figurative. "Images defended from the injuries of the weather by niches of stone wherein they are placed." (Evelun) Origin: F, fr. It. Nicchia, prop, a shell-like recess in a wall, fr. Nicchio a shellfish, mussel, fr. L. Mytilus. Source: Websters Dictionary (01 Mar 1998) |

| ecological chemistry | Chemistry that concentrates on the effects of woman-made chemicals on the environment as well as the development of agents that are not harmful to the environment. The study of the molecular interactions between species and between species and the environment. (05 Mar 2000) |
| ecological ectocrine | A chemical substance that undergoes biosynthesis in one species and that exerts an effect on the function of another species through mechanisms of the external environment; e.g., the biosynthesis of vitamins by ruminants and their subsequent ingestion by other animals. See: ectohormone. (05 Mar 2000) |
| ecological epidemiology | <epidemiology> A branch of epidemiology which views disease as a result of the ecological interactions between populations of hosts and parasites; what we do. We contrast this with classical epidemiology. (05 Dec 1998) |
| ecological fallacy | The bias that may occur because an association observed between variables at an aggregate level does not necessarily represent an association that exists at an individual level; an error of inference due to failure to distinguish between different levels of organization. (05 Mar 2000) |
| ecological protection | <ecology> Protection consists of measures undertaken to protect and preserve elements of an ecosystem's structure and functions against future degradation. (10 Nov 1998) |
| ecological restoration | <ecology> The process of renewing and maintaining ecosystem health. Ecological restoration is the process of intentionally altering a site to establish a defined, indigenous, historic ecosystem. The goal of this process is to emulate the structure, function, diversity, and dynamics of the specified ecosystem. (10 Nov 1998) |
| ecological system | <ecology> An ecosystem is the dynamic and interrelating complex of plant and animal communities and their associated non-living environment. The physical and climactic features and all the living and dead organisms in an area that are interrelated in the transfer of energy and material. An interacting complex of a community and its environment functioning as an ecological unit in nature. Differs from system in being a more rigorous definition that encompasses and requires assumptions of energetics, ecological interactions, species adaptations and so forth. (13 Nov 1997) |
| ecological systems, closed | Systems that provide for the maintenance of life in an isolated living chamber through reutilization of the material available, in particular, by means of a cycle wherein exhaled carbon dioxide, urine, and other waste matter are converted chemically or by photosynthesis into oxygen, water, and food. (12 Dec 1998) |
| ecological niche | (ecology) the status of an organism within its environment and community (affecting its survival as a species) |
