| Terms for subject Environment (5878 entries) |
| anaerobic process (A process from which air or oxygen not in chemical combination is excluded) | عملية لاهوائية | |
| anaerobic treatment (Breakdown of organic material without the presence of oxygen, a treatment which permanently removes the unpleasant odour of many organic wastes so that they can be used on agricultural land) | معالجة لاحيوية هوائية | |
| analysis (Examination or determination) | تحليل | |
| analysis programme (No definition needed) | برنامج تحليل | |
| analytical chemistry (The branch of chemistry dealing with techniques which yield any type of information about chemical systems) | الكيمياء التحليلية | |
| analytical equipment (Equipment employed in analytical techniques) | أجهزة التحليل | |
| analytical method (No definition needed) | أسلوب التحليل | |
| anatomy (The science concerned with the physical structure of animals and plants) | تشريح | |
| angiosperm (The class of seed plants that includes all the flowering plants, characterized by the possession of flowers. The ovules, which become seeds after fertilization, are enclosed in ovaries. The xylem contains true vessels. The angiospermae are divided into two subclasses: Monocotyledoneae and Dycotiledoneae) | كاسيات البِزْر | |
| angling (The art or sport of catching fish with a rod and line and a baited hook or other lure, such as a fly) | الصيد بالصنارة | |
| animal (Any living organism characterized by voluntary movement, the possession of cells with noncellulose cell walls and specialized sense organs enabling rapid response to stimuli, and the ingestion of complex organic substances such as plants and other animals) | حيوان | |
| animal behaviour (Behaviour of animals in their normal environment, including all the processes, both internal and external, by which they respond to changes in their environment) | سلوك الحيوان | |
| animal biology (The scientific study of the natural processes of animals) | البيولوجيا الحيوانية | |
| animal conservatory (Areas for the conservation of rare or endangered animal species) | محمية حيوانية | |
| animal corridor (Line corridors (roads, paths, and hedgerows) which lack interior habitat but may serve as movement groups for organisms. Corridors may also provide an efficient migratory pathway for animals. The presence or absence of breaks in a corridor may be a very important factor in determining the effectiveness of its conduit and barrier functions) | ممر للحيوانات | |
| animal damage (Harm caused to the environment by animals as, for instance, in the case of overgrazing, trampling, etc. Overgrazing damage is reduced by properly located watering facilities to decrease daily travel by livestock. Rotation of grazing areas allows time for recovery of grass. Some land can be easily restored if grazing is allowed only during one season. Animals may cause damage to crops when agriculture land borders on virgin territory or game reserves. In addition wild animals may bring disease in valuable domestic herds. Cattle overstocking has caused serious degradation of habitat, and cattle raising is thus, to some extent, counterproductive) | أضرار الحيوانات | |
| animal disease | مرض حيواني | |
| animal displacement (The habit of many animal species of moving inside their habitats or of travelling, during migrations, to different biotopes, often considerable distances apart; in aquatic environments displacements can occur horizontally or vertically while in terrestrial environments animal populations that breed in the alpine or subalpine zones in summer, move to lower levels in winter; animal displacements usually follow circadian rhythms and are related to the necessity of finding breeding, resting and feeding areas) | نزوح الحيوانات | |
| animal dung as fuel (Excrement from animals that may be dried and burned to generate energy or converted to liquid or gaseous fuels, such as methane, through chemical processes) | استخدام روث الحيوانات وقودًا | |
| animal ecology (A study of the relationships of animals to their environment) | إيكولوجيا الحيوان |
