Webb30 juni 1997 · These upper and lower limits of the Shannon diversity index are helpful for the interpretation of data and are useful for calculating an eveness index (i.e., a relative diversity index) which as sesses how individuals of the community are dis tributed among present species (see Hurlbert, 1971). Webb11 apr. 2024 · We calculated the Shannon index, and total species richness by peatland. The Shannon index is one of the most widely used diversity indexes in ecology, it takes the value 2 as a reference value, lower values indicate low diversity environments and greater than 3 high diversity, this index gives higher values to equitable communities.

WebbShannon evenness index (Shannon's equitability index) is a pure diversity index, independent of species richness. It measures how evenly the microbes are distributed in a sample without considering the number of species. Values can range from zero to one: from high dominance of a single species to perfectly equal abundances across all species. http://www.thejaps.org.pk/docs/v-23-2/23.pdf eastern white pine - 50 pack pinus strobus
