Jul 30, 2012 · Background Theory suggests that biodiversity can act as a buffer against disturbances and environmental variability via two major mechanisms: Firstly, a stabilising effect by decreasing the temporal variance in ecosystem functioning due to compensatory processes; and secondly, a performance enhancing effect by raising the level of community response through the selection of better performing ...

Sep 19, 2012 · Despite the fact that the inclusion of a dominant species per se did not influence the effect of species diversity on community-level biomass, when the diversity within the dominant species was taken into account, the relationship between species diversity and biomass was altered. Specifically, as genetic diversity within the dominant species increased, the relationship between species ...

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 ...

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.

Dec 7, 2021 · Previous studies have shown that species interactions (such as competition, predation, or parasitism) can influence species’ responses to environmental change 19,22,23,24 and that this effect ...
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 ...
Secondly, some species do better in the shared optimal environment than others (in Figure 8.5B yellow can perform the best in the optimal environment. We call this species dominant over the other species. The dominant species would competitively exclude (or at least greatly lower the abundance of the other species) in the optimal environment.
