- ecological amplitude (alt. ecological valence)
- The variety of environmental conditions within which an organism can survive and replace itself, or a process can function. See also: tolerance, optimum, pessimum.
|
- ecological bonitation
- The numerical statement of well-being of an organism or group during a season or in a specific locality. See also: bonitation, biotic potential.
|
- ecological efficiency
- A mathematical statement of the ratio between the energy available to an organism or group or group processes, and the energy actually expended. For example, a bear may use less calories to hunt a rabbit during the summer than the calories gained from the rabbit, but winter hunting expends more than is gained, so it is more ecologically efficient for bears to hibernate. A 10 percent gain is average, 20 percent very good, 5 percent typical of the top of the food chain.
|
- ecological equilibrium
- See also: the balance of nature, dynamic equilibrium.
|
- ecological equivalence
- The case in which two or more species have enough similarities so that any could replace the other in a specified habitat. See also: ecological amplitude, niche.
|
- ecological equivalent
- An organism capable of replacing another in a habitat. See also: ecological equivalence, vicariation.
|
- ecological factor
- Any variable of the environment that impacts the life of one or more organisms. May be classified into A: climatic, physiographic, edaphic and biotic factors; or B: direct, indirect, and remote factors. See also: biotic, limiting factor, density dependent factor.
|
- ecological longevity
- Life span; the average length of life of a species under stated conditions.
|
- ecological pyramid (alt. pyramid of numbers, Eltonian pyramid)
- The concept that in most food chains, the number of individuals decreases at each stage, with huge numbers of tiny individuals at the base and a few large individuals at the top, as displayed by millions of plankton, a moderate number of large fish, and a few eagles.
|
- balance of nature (alt. ecological balance, alt. biotic balance, syn. dynamic equilibrium, syn. biotic equilibrium)
- A term for an ideal condition in which the interrelationships of organisms to one another and their environment appear harmonious, like a climax forest. In reality, the balance is continually upset by natural events.
|
- bonitation (alt. ecological bonitation)
- The state of well being in a population, reflected by increasing numbers of individuals.
|
- ecology (adj. ecological)
- The study of the relation of organisms to their environments.
|
- ecotype (syn. ecological race, adj. ecotypic)
- A subdivision of an ecospecies that survives as a distinct population through environmental selection and isolation; comparable to a taxonomic subspecies.

Notes:
- This is version: 2.1 Last updated: February 4, 2002.
- If you are looking up names of plants, check the HortiPlex plant database here at GardenWeb.
- Proper nouns are generally not included in the glossary.
- Searches are case insensitive.
- You can browse the glossary, but there are many pages.
- Multiple keywords can be searched so that each word must appear in each hit (boolean "and") or so that only one of the words must appear (boolean "or").
- To increase the chances of matching keywords with multiple endings, search for "Word Roots." With this setting, epiphyt will match both epiphyte and epiphytic.
- You can also limit your search to just terms or just definition.
- Additional Passes: If there are no hits in the first search, common word endings (-ing, -es, -ed, -ly) are stripped from the keywords and a second pass is made. If there is still no match, all non-word characters are stripped.
- This glossary was compiled by the editors of GardenWeb from a variety of sources. It is updated continually.
- If you encounter any problems, or feel that there are terms that should be in the database and are not, please let us know.
