Mar 13, 2019 · By using relative abundance of a dominant species, studies can focus on identified dominant species as an additional potential driver of ecological processes, alongside other diversity measures, such as richness and evenness. By our definition, dominant species must have an effect on at least one community, ecosystem, or environmental property.

Mar 22, 2024 · We ascribe this to the dominant species effect, whereby few, yet abundant (in terms of biomass) species exert the largest effect on ecosystem functions through their traits (de Bello et al., 2021). In our study, fast-growing communities were dominated by species with resource-acquisitive strategies, which match the typical ecological profile of competitive-ruderals with rapid growth of biomass ...

Strains A, D and E had highest activity at 26°C, strain B was most active at 22°C and strain C did not differ significantly over the temperature range studied (Additional file 2). All strains showed some activity over the entire temperature range, even though two of them (B and D) showed a rapid decline in activity when the temperature was increase...
Under constant temperature conditions, species richness had an overall positive effect on the mean respiratory activity, but successive levels of species richness were not always significantly greater than the previous level (Table 1, Figure 1). Under varying temperature conditions, species richness had the greatest influence on respiratory activit...
Under constant temperature conditions, differences in species composition had strong effects on respiratory activities (Table 1, Figure 3), where highest levels of activities were observed in communities that contained strain A and/or strain C (Figure 3). Also in case of the fluctuating temperature regime, the functional contributions that individu...

Predation can have large effects on prey populations and on community structure. Predators can increase diversity in communities by preying on competitive dominant species or by reducing consumer ...
Dec 20, 2016 · The ecological consequences of species loss are widely studied, but represent an end point of environmental forcing that is not always realised. Changes in species evenness and the rank order of ...

Sep 10, 2021 · The ‘selection effect’ in Loreau and Hector's theory favors dominance of a mixture by species or genotypes with dominant traits leading to a higher competitiveness such as higher height or leaf nitrogen content (LNC) in monoculture at the expense of others (Atwater and Callaway, 2015; Cadotte, 2017; Fox, 2005), which seems analogous to natural selection in evolution.

Dominant species: Species that have high abundance relative to other species in a community, and have proportionate effects on environmental conditions, community diversity and/or ecosystem function. Dominant species can be common (widespread) or restricted in their range (limited). Foundation species: Species that have large effects on their
