Species evenness is a measure of the relative abundances of species within a community. Quantitative metrics of species diversity, such as the Shannon Index or Simpson Index, …

Thus, species evenness can affect grassland ecosystem processes indirectly by affecting species richness, and it will be imperative to understand how nonrandom extinctions affect NPP in …

Mar 21, 2025 · Habitat with even species richness means that all species are equally represented while low evenness implies dominance by one or two species. This paper aims to discuss the …

Oct 1, 2004 · We experimentally varied, for the first time, both species richness (1–8 perennial species/m 2) and species evenness (near maximal vs. realistically low) in grassland plots. Net …

The Shannon index factors in both species evenness and species richness, as represented by the variables p i and s, respectively. The lowest possible value of H is zero, and the higher a …

Jan 6, 2025 · Pielou’s Evenness Index (also known as the Shannon Equitability Index) helps ecologists measure and understand these distribution patterns, revealing how equitably …

Oct 28, 2024 · Species evenness refers to how close in numbers each species in an environment is. So if there are 40 foxes and 1000 dogs, the community is not very even. But if there are 40 …

When species evenness is low, a few species dominate the ecosystem while others remain rare. This can make the ecosystem less stable and more vulnerable to disturbances like disease …

Nov 10, 2017 · Both the effects of maximum and minimum evenness, and of a key set of intermediate evenness levels, can be derived from species richness – ecosystem function …

Apr 6, 2023 · A low level of evenness indicates that an ecosystem is dominated by a few species. This can be problematic for the ecosystem’s stability because if one of those dominant species …
