- You are an ecologist studying the biodiversity of islands in a tropical archipelago. Using the species-area relationship, you aim to estimate the number of species on a newly discovered island with an area of 220 km². Your research has established that the y-intercept of the species-area relationship (log S = log c + z log A) is 1.09 and the slope (z) is 0.38. Based on these parameters, how many species would you expect to find on this island?

Denoted as H, this index is calculated as: H = -Σpi * ln(pi) where: Σ: A Greek symbol that means “sum” ln: Natural log pi: The proportion of the entire community made up of species i The higher the value of H, the higher the diversity of species in a particular community. The lower the value of H, the lower the diversity. A value of H = 0 indicates a community that only has one species. The Shannon Equitability Index is a way to measure the evenness of species in a community. The term “evenness” simply refers to how similar the abundances of different species are in the community. Denoted as EH, this index is calculated as: EH = H / ln(S) where: H: The Shannon Diversity Index S: The total number of unique species What is the Shannon diversity index value for this community?
