The species diversity in a region is investigated by the indices (species richness, evenness and biodiversity) and their common methods of measurement (evenness index: Simpson, Camargo and Smith & Wilson; biodiversity index: Shannon-Wiener, Brillouin and Simpson). Species richness has been the subject of biodiversity studies more often than species evenness. For instance the two community, they have the same number of species therefore the same species richness. But independently of […] Environmental geometry and heterogeneity–diversity relationships in spatially explicit simulated communities. Significant species richness × evenness and spatial pattern × evenness interactions were found when analysing functions such as organic C, total N and the activity of phosphatase. Species richness and evenness are negatively corrected at relatively small scales (0.5 m×0.5 m to 2 m×2 m), but this negative relationship vanishes at larger scales (≥2 m×4 m). Disturbance increases negative spatial autocorrelation in species diversity. The main components of species diversity are richness and evenness. Reproducibility of the multi‐component aspect of species diversity across different areas and scales: towards the constitution of a shortlist of complementary indices for monitoring fish diversity?.
