You are comparing species diversity between four different habitats: which of the
following habitats is the most diverse?
Habitat A has 15 species total, with approximately equal representation across
all species
Habitat B has 15 species total, and is dominated by two of its fifteen species
Habitat C has 3 species total, with approximately equal representation across all
species
Habitat D has 3 species total, and is dominated by one of its three species
Habitats A and B are equally diverse

What is the species Evenness of this community? 0.34 0.84 0.62 0.71arrow_forwardEcology and Biology: Shannon Diversity Index: Definition & Example The Shannon Diversity Index (sometimes called the Shannon-Wiener Index) is a way to measure the diversity of species in a community. 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?

- You have been researching the biodiversity of different species of lizards in the Florida Everglades. You select a one square acre plot of land and begin tagging and counting the different reptiles found in that area over 6 months. After 6 months of research, you collected the following data: Species Count Green Anole 16 Brown Anole 72 American Alligator 3 Burmese python 2 Corn Snake 9 Eastern Glass Lizard 8 Use the blanks below to answer the following questions: 1. What is the biodiversity index of the one acre lot observed? 2. If you collected the same information for a second square acre 10 miles away and determined that acre to have a biodiversity index of 0.37, would you consider the first area to be biologically diverse and why or why not? 3.
