Study site was devided into 3 station as sampling location. Data sampling of identifying the type, density and calculating the value of diversity index (ID) according to Shannon Wiener for-mula. Investigations carried out measurements of environmental parameters, namely tempera-ture, pH and Dissolved Oxygen. The result showed that 1) identified 20 kinds of plankton in Pepe river Surakarta namely Spirogy- ra, Eustbidentat, Pleurosigma, Oscilatoria, Euglena, Aungilospora, Gonatozygon ...
Apr 24, 2009 · Shannon-Wiener Diversity Index? What does H' represent? My results gave me H's of: 1.321, 1.215, 1.195, 1.01 but i'm not exactly sure what this means (I know it has something to do with species diversity).
diversity index is the Shannon-Weiner index  H =−PilnPi Where H = Shannon-Weiner index, Pi = N ni, ni = Number of individuals of a species, N =Total individuals of all species The diversity index criteria are as follows: H’ ≤ 1 = Low diversity 1 < H’≤ 3 = Moderate diversity H ’≥ 3 = high diversity 2.2. Evenness Index
The three methods recovered similar species richness (26 species from fruiting bodies, 32 species from mycelia, and 32 species from 454 sequencing), but Fisher’s alpha, Shannon-Wiener, Simpson’s diversity indices of fungal communities indicated fruiting body collection and mycelial isolation displayed higher diversity compared with 454 ...
use the Shannon-Wiener diversity index, or H'. This index is borrowed from information science, and is calculated as follows: € H'=−p i lnp i i=1 S ∑ Where p i is the relative abundance of species i, S is the total number of species present and ln is the natural log. Let's use R to calculate H' for the two communities in the example above.
In isolated forest fragments, Shannon-Wiener diversity was signifi-cantly higher than in lowland forest, and the abundance of Heteroptera was higher in lowland forest than in young teak plantations. We also found that the Berger-Parker dominance index was lower in isolated forest fragments than in lowland forest.
Abstract: Species diversity is the most important component of biodiversity and plays an important role in maintaining forest ecosystem processes and stability. The assessment of the forest conservation value of species diversity is commonly carried out based on the Shannon-Wiener index.
