Using the complementarity procedure, ... , and the diversity is calculated using the Shannon–Weaver diversity index through the following formula: H = −∑ [(ni/N) ln ... WebbLet’s compute the Shannon-Weiner diversity index for the same hypothetical community in the previous example. Example 2a We know that N = 65. Now let’s compute the index: = Rank Abundance Graphs Species abundance distribution can also be expressed through rank abundance graphs.
WebbMathematically it is defined as a diversity index, a measure of biodiversitywhich quantifies how equal the community is numerically. So if there are 40 foxes and 1000 dogs, the community is not very even. But if there are 40 foxes and 42 dogs, the community is quite even. J′=H′Hmax′{\displaystyle J'={H^{\prime } \over H_{\max }^{\prime }}}
