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 the dominant species present.
Oct 12, 2024 · Dominance, in genetics, greater influence by one of a pair of alleles that affect the same inherited character. In ecology, the term dominance refers to a species of animal or plant that exerts the most influence on other species of its community because its members are the most abundant or the largest.

What is a dominant species?
In ecology, a dominant species refers to the group of organisms (or species) that have the most significant influence or control over the other organisms in its ecological community. A similar definition of it is in biology. Adominant species is a species that prevails in an ecosystem, especially when they are the most numerous and have a high ecological impact. This means they constitute the majority of the biomass. And because of high numerical advantage, dominant species tend to have an im...
What makes a species dominant?
Avolio et al. (2019) provided a summary of the characteristicsor traits that make a species potentially dominant. Several factors are at play (e.g, ecological, biological, genetics, spatial, evolutionary, etc.). Here is a summary of the types of dominance to explain the mechanism of ecological dominance. 1. Dominance by resource acquisition, three possible ways to explain this type of dominance: (1) based on the resource-ratio hypothesis, the species with the lowest equilibrium resource requi...
What’s the ecological role of dominant species?
Dominant species had an important role in the coexistence, distribution, and structuring of species. In ecology, species that are considered dominant have great population sizes as well as in productivity as compared to their competitors. In the ecological environment, the dominance of species depends on many factors like moisture, groundwater condition, and temperature. Ecological dominance impacts competition. Due to the availability of limited necessary resources for survival, competition...
Are humans a dominant species?Based on studies, of the earth’s total biomass, almost 80% is from plants. The findings of this study were published in Proceedings of the National Academy of Sciences USA. Humans occupy a small proportion of the total biomass. See the small pink dot as compared with the huge green dot denoting the plant biomass. The h...

They play crucial roles in shaping the ecosystem, affecting the types of organisms that can thrive in their environment, and influencing nutrient cycling and energy flow. Their presence can determine the composition of other species and often establishes ...
Mar 3, 2024 · Dominant species refers to the organism that has the greatest impact on an ecosystem and outcompetes other species in a specific environment. In ecology, it is the species that holds the highest abundance or biomass.
Aug 27, 2024 · Dominance: At each trophic level, one or two species exert more dominance over the function and structure of the community. These dominant species impact on the population and activities of other organisms, thus affecting the nature of the community. The ecological dominants may change the abiotic conditions of a habitat over a period of time.
