The mass ratio hypothesis
SpletThe "mass ratio" effect posits that the overall function of the ecosystem is driven mostly by the dominant species and so really its the relative abundance in a given sample of tree is … SpletThe K/U Ratio is the ratio of a slightly volatile element, potassium (K), ... It is calculated as a ratio of one to the other on an equal mass basis which is often ... The ratios of the Moon's volatile elements are not explained by the giant-impact hypothesis. If the giant-impact hypothesis is correct, they must be due to some other cause.

Splet20. jan. 2014 · First, the mass ratio hypothesis (Grime 1998) states that the effect of a species on a given ecosystem process is proportional to its relative abundance in the community. This is because the participation of species on the processes of matter transformation and energy flux is proportional to their contribution to the community … Splet22. nov. 2024 · As proposed by Grime , we found that mass ratio effects rather than declines in richness per se is a key mechanism driving loss in function and underlying …

(Grime, 1998). Thus, for some species that could be abundant, widespread, or common but may have little impact on the community or the ecosystem, for example, because of their relatively small physical size, these species …
