see Hierarchy
() ( Silvic.). A tree forming part of the dominant tree class. See Tree classes, Appendix II. () ( Ecol.). That constituent of plant community which exerts the greatest influence on its character. () ( Genl.). A species of the upper canopy. ( BCFT).
More prevalent than any other species and determines the appearance and composition of the community.
A common species that is always dominant in the sub-association. It has the greatest biomass and is generally the most frequent. Any number of species could be dominant e.g. 1,2,3,4 or 5 depending on the association. See also co-dominant and sub-dominant. Wilson and Brocklehurst, pers. comm., 2000
the most numerous or weighty species in a community.
a species with greater influence than any other in its biotic community, changing the lives of other species and the character of the habitat
the most common, often largest species in a community
Having power, control and privilege over others within a social hierarchy.
a species that exerts a considerable influence on, or defines the character of, a community because of such factors as its number, coverage, or size.
(1) Plant species or species groups that, by means of their number, coverage, or size, have considerable influence or control upon the conditions of existence of associated species. (2) Those individual animals that, by their aggressive behavior or otherwise, determine the behavior of one or more animals resulting in the establishment of a social hierarchy.
When referring to plants in this document, the plant covering the most ground. Dominance refers to ecological dominance, so a plant that does not cover the most ground may be exerting more control than it's extent indicates. Usually cover is a pretty good indicator of dominance, and it is relatively simple to measure.
an individual or species of the upper layer of the canopy
an organism, group of organisms, or taxon that by its size, abundance, or coverage exerts considerable influence upon an association's biotic (such as structure and function) and abiotic (such as shade and relative humidity) conditions.
exerting forcefulness or having dominance in a social hierarchy.
