WebEcological Research: Measuring & Analysis. Previously in this lesson, we learned that high biodiversity is essential to a healthy ecosystem. Thus, monitoring the biodiversity and the sustainability of the ecosystem is … WebAlthough the trait concept is increasingly used in research, quantitative relations that can support in determining ecological tipping points and serve as a basis for environmental standards are lacking. This study determines changes in trait abundance along a gradient of flow velocity, turbidity and elevation, and develops trait–response curves, which …

WebShannon or Shannon--Weaver (or Shannon--Wiener) index is defined as H ′ = − ∑ i p i log b p i, where p i is the proportional abundance of species i and b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 (which makes sense, but no real difference). Both variants of Simpson's index ...
