Mar 13, 2019 · Such approaches could use remote sensing to track changes in dominant species (Pau & Dee, 2016), plant functional properties at large spatial scales (Jetz et al., 2016) or utilize plant spectral data, which has been found to be a good proxy for plant function, identity, as well as important ecosystem functions (Cavender-Bares et al., 2016b; Schweiger et al., 2018).

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...

In ecology, it is the species that holds the highest abundance or biomass. Dominant species play a crucial role in shaping ecosystems by virtue of their large population size, high reproductive capacity ...
A dominant species is a plant, animal or functional group of different species most commonly or conspicuously found in a particular ecosystem. It is generally the most populous species or comprises the greatest biomass in an ecosystem. It also influences the distribution of other organisms and helps define the ecosystem and its characteristics.
Sep 1, 2020 · Dominant plant species (see Glossary) greatly affect ecosystem functions such as biomass production, nutrient cycling, and carbon sequestration [1]. So far, studies of dominance are heavily biased towards its aboveground dimension, a widespread shortcoming also in plant functional ecology, community ecology, and global change science [ 2 , 3 ].

Our analysis provides empirical evidence that plant functional community structure and global patterns in primary productivity are linked through the resource economics and size traits of the dominant species. This is an important test of the hypotheses underlying BEF relationships at the global scale.

Mar 13, 2019 · Based on a review of historical and contemporary definitions we develop a synthetic definition of dominant species. This definition incorporates the relative local abundance of a species, its ubiquity across the landscape, and its impact on community and ecosystem properties. A meta-analysis of removal studies shows that the loss of species ...
