Increasing the area sampled increases observed species diversity both because more individuals get included in the sample and because large areas are environmentally more heterogeneous than small areas. WebGraph shows principles of intermediate disturbance hypothesis: I. at low levels of ecological disturbance species richness decreases as competitive exclusion increases, II. at intermediate levels of disturbance, diversity is maximized because species that thrive at both early and late successional stages can coexist, III. at high levels of … WebJan 12, 2012 · Species evenness and richness contributed 34% and 13% of the explained variation, respectively ( Fig. 1 ). ln (ES) increased with richness from 2 to 6, then plateaued with richness ≥ 6 ( Fig. 2a ).

WebDec 17, 2024 · First, tree species richness may increase community stability indirectly via promoting asynchrony through functional diversity in traits related to drought tolerance (hereafter “drought-tolerance diversity”). The importance of tree species richness and asynchrony for community stability is supported by previous studies ( 5, 11 – 13 ). WebThe EDG states that species richness tends to increase as elevation increases, up to a certain point, creating a "diversity bulge" at middle elevations. There have been multiple hypotheses proposed for explaining the EDG, none of which accurately describe the phenomenon in full.

The observed species richness is affected not only by the number of individuals but also by the heterogeneity of the sample. If individuals are drawn from different environmental conditions (or different habitats), the species richness of the resulting set can be expected to be higher than if all individuals are drawn from similar environments. The accumulation of new species with increasing sampling effort can be visualised with a species accumulation curve. Such curves ca… WebApr 12, 2024 · Increase of local seeded species richness did not depend on any treatments (Figure 1b, Table S4b ), while the increase of novel seeded species richness was contingent on herbivore exclusion and warming, being lowest when plots were grazed and warmed (Figure 3a, Figure S3a and Table S4c ).

WebApr 20, 2024 · Because both biotic homogenization and differentiation may be common, the direction of scale-dependence of species richness change following human impacts will be variable. As we illustrate below, the magnitude of species richness change can increase with scale under biotic homogenization, but decrease with scale under biotic differentiation.

Webspecies richness increases with stream size, reaching a maximum in midorder streams and then decreasing in very large rivers.
