Shannon weiner index of diversity
WebbAlthough there have been a lot of studies dealing with species diversity of natural deciduous forests, the Shannon–Weiner index or Simpson index was mostly used. Other indices such as Log series, Margalef index, McIntosh index, and Berger–Parker index were seldom used in describing forest community attributes with species diversity indices. WebbShannon 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 was also found that the fundamental components of the Shannon–Wiener index measure dominance concentration rather than evenness, with …
WebbIn particular, for a random sample, we can use Shannon’s index of diversity (aka as Shannon-Weiner’s index), which is defined as. Here, ni is the number of observations … WebbShannon-Weiner Index of Diversity There are many methods that ecologists use to calculate species diversity. The Shannon-Weiner Diversity Index is a common way of showing that diversity involves not only numbers of different species, but also how well each of these species is represented in different habitats.
WebbDuring the study, a total of 78 fish species including 69 native and 9 exotic fish species were recorded belonging 10 orders and 26 families. The values of Shannon-Weiner diversity index ( H') indicated a good spread of fish population in Chalan Beel although the number of species was not found satisfactory.
