WebbA simple biodiversity index is calculated as follows: number of species in the area ÷ total number of individuals in the area = biodiversity index. For example, a 4 X 4 meter square area in a carrot patch has 300 carrot plants, all the same species. It has a very low biodiversity index of 1/300, or 0.003. A 4 X 4 meter square area in the ... WebbUse the Shannon-Weiner index to calculate species diversity for the three communities shown in the table above. Use either equation 2 or equation 3. Equation 3 is easier. Show your work for Community A. It is not necessary to show your work for Communities B and C. H' = - pi ln pi Equation 2 Where pi = the proportion of individuals of species i.
Webbrelation to Shannon’s formula is pointed out in [2], the notation is cumbersome, and the relevance to practical communication systems is far from obvious. Reference to … Webbindices to measure species diversity and the whole subject area has become confused with poor terminology and an array of possible measures. Chiarucci (2012) and Magurran and McGill (2011) have reviewed the problem. The problem at present is that we have a diversity of measures for communities but they do not always perform well (Xu et al. …
