Both the composition and abundance of species within an ecosystem can be affected by the dominant species present. [2] In most of the world's ecosystems, biologists have repeatedly observed a rank-abundance curve in which ecosystems comprise a handful of incredibly abundant species, but more numerous, rarer species that are few in number.
The cichlid social dichotomy is composed of a single dominant with multiple subordinates, where the physical aggression of males becomes a contest for resources [32] (mates, territory, food). Female cichlids prefer to mate with a successfully alpha male with vivid coloration, whose territory has food readily available.
In many monogamous bird species, the dominant pairs tend to get the best territories, which in turn promote offspring survival and adult health. In dunnocks, a species of bird that experiences many mating systems, sometimes individuals will form a group that will have one dominant male who achieves all of the mating in the group. [12]
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 ...
Several causal mechanisms have been proposed for the formation of monodominant forest in tropical ecosystems, [9] [1] including features of the environment such as low disturbance rates, and intrinsic characteristics of the dominant species: escape from herbivores, high seedling shade-tolerance, and the formation of mycorrhizal networks between ...
Species population is a science falling under the purview of population ecology and biogeography. Individuals are counted by census, as carried out for the piping plover ; [ 3 ] [ 4 ] using the transect method , as done for the mountain plover ; [ 5 ] and beginning in 2012 by satellite, with the emperor penguin being first subject counted in ...
The New Scientist have listed Dominant Species as one of the "9 of the best board games to play for fans of science and tech". [14] According to Andrew Smith: Dominant Species can be a mean, frustrating game of survival of fittest. But the game mechanisms are extremely streamlined, easy to teach, and fairly intuitive to understand.
The intermediate disturbance hypothesis (IDH) suggests that local species diversity is maximized when ecological disturbance is neither too rare nor too frequent. At low levels of disturbance, more competitive organisms will push subordinate species to extinction and dominate the ecosystem. [1]
