WebbTo determine the diversity of plankton and benthos communities, the following calculation formula is used: (Ministry of Environment, the Republic of Indonesia No. 115/2003) where: H’ is Shannon Wiener diversity index and ni is number of individu within same species and N is total number of individu species found. Tabel 2. WebbShannon-Wiener diversity index The most widely used diversity index in the ecological literature is the Shannon-Wiener diversity index [6] [7] . It assumes that individuals are … WebbMoreover both the Shannon-Wiener and Simpson diversity indexes were calculated higher in organic apple orchards and found with similar results as species richness for both study years. t shirt diffuser
