Webb10 apr. 2024 · The study was conducted to assess the current biodiversity in Chalan beel, Natore district, Bangladesh. Primary data were collected through stratified random sampling and analyzed through a combination of descriptive statistical and mathematical techniques. The Shannon-Weiner and Margalef richness indices were used to quantify … WebbTable 1 shows that the Shannon entropy or Shannon-Wiener index is converted to effective number of species or true diversity by taking the exponential: exp (1.609) is 5.000, so the true diversity according to the Shannon entropy is also 5.000 species.
