Dominance (ecology)
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) or make 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.

Tridens Muticus
''Tridens muticus'' is a species of grass known by the common name slim tridens. It is native to Mexico and the southwestern quadrant of the United States. Distribution It grows several types of habitat, including plateau and desert, woodlands, sagebrush, plains, and other areas with dry sandy and clay soils. Description It is a perennial grass forming a thick tuft with a knotted base and rhizome. It reaches a maximum height of 50 to 80 centimeters. The panicle has short branches appressed to the others, making the inflorescence narrow. The florets are generally purple in color. This plant uses C4 carbon fixation carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants.

Aristida
''Aristida'' is a very nearly cosmopolitan genus of plants in the grass family. ''Aristida'' is distinguished by having three awns (bristles) on each lemma of each floret. The genus includes about 300 species found worldwide, often in arid warm regions. This genus is among those colloquially called three-awns wiregrasses, speargrasses and needlegrasses. The name ''Aristida'' is derived from the Latin " arista", meaning "awn". They are characteristic of semiarid grassland. The Wiregrass Region of North America is named for '' A. stricta''. Other locales where this genus is an important component of the ecosystem include the Carolina Bays, the sandhills of the Carolinas, and elsewhere, Mulga scrub in Australia, and the xeric grasslands around Lake Turkana in Africa. Local increases in the abundance of wiregrasses is a good indicator of overgrazing, as livestock avoid them. Description ''Aristida'' stems are ascending to erect, with both basal and cauline leaves.

Bouteloua
''Bouteloua'' is a genus of plants in the grass family. Members of the genus are commonly known as grama grass. Taxonomy and systematics The genus was named for Claudio and Esteban Boutelou, 19th-century Spanish botanists. David Griffiths produced a 1912 monograph on the genus. Description ''Bouteloua'' includes both annual and perennial grasses, which frequently form stolons. Species have an inflorescence of 1 to 80 racemes or spikes positioned alternately on the culm (stem). The rachis (stem) of the spike is flattened. The spikelets are positioned along one side of the spike. Each spikelet contains one fertile floret, and usually one sterile floret. Distribution ''Bouteloua'' is found only the Americas, with most diversity centered in the southwestern United States. Uses Many species are important livestock forage, especially blue grama.

They are native to the hot and dry (arid) parts of the Americas and the Caribbean. Early reports of the species were confused with the cassava (''Manihot esculenta''). Consequently, Linnaeus mistakenly derived the generic name from the Taíno word for the latter, ''yuca''.
