Ecological dominance is the degree to which one or several species have a major influence controlling the other species in their ecological community (because of their large size, population, productivity, or related factors) [1] or make up more of the biomass. Both the composition and abundance of species within an ecosystem can be affected by ...
Dominant species may mean: Dominant species (ecology), one of a small number of species which dominate in an ecological community; Dominant Species (novel) by Michael ...
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
An image of ecological succession, starting with pioneer species and ending with an old-growth forest that is dominated by climax species, which is denoted by VIII. Climax species, also called late seral , late-successional , K-selected or equilibrium species, are plant species that can germinate and grow with limited resources; e.g., they need ...
Species also interact with other species that require the same resources. Consequently, interspecific competition can alter the sizes of many species populations at the same time. Experiments demonstrate that when species compete for a limited resource, one species eventually drives the populations of other species extinct.
The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown. A species (pl.: species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1]
Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
Dominance hierarchies are found in many species of bird. For example, the blue-footed booby brood of two chicks always has a dominance hierarchy due to the asynchronous hatching of the eggs. One egg is laid four days before the other, and incubation starts immediately after laying, so the elder chick is hatched four days before the younger ...
