Dominance (ecology)

Ecological dominance is the degree to which a taxon is more numerous than its competitors in an ecological community, or makes up more of the biomass. Most ecological communities are defined by their dominant species.

  • In many examples of wet woodland in western Europe, the dominant tree is alder (Alnus glutinosa).
  • In temperate bogs, the dominant vegetation is usually species of Sphagnum moss.
  • Tidal swamps in the tropics are usually dominated by species of mangrove (Rhizophoraceae)
  • Some sea floor communities are dominated by brittle stars.
  • Exposed rocky shorelines are dominated by sessile organisms such as barnacles and limpets.
