A(n) community is a group of species that occupy the same area. When studying the diversity of a group of species, ecologists use two measures: One is a count of the total number of species in the area, which is called The other is a measure of how common the species are, compared to each other, which is called

You have determined that a community consisting of 12 species has Shannon Diversity index score of 1.784. What is the species Evenness of this community? 0.34 0.84 0.62 0.71

Choose one of the following factors and explain how and why species richness varies with it: temporal variation, latitude, succession. Give a specific example.

Ecology 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? What…

Species richness quantifies the amount of money each species is valued at on the biodiversity stock exchange the relative abundance of species in a community. the number of species in a community the combination of the number of species in a community and their relative abundances

Based on the images provided, the distribution of animals seen is dependent on which one of the following?  Explain your choice. species population size community ecology spatial scale immigration and emigration

USING THE RAINFOREST get data for the following. Dominant plant and animal species Keystone species:  Amount of precipitation:Geographic location:

In a 50 square mile section of forest, there are some cut patches of forest where the trees have been removed and some patches of forest that have been left uncut. Birds are nesting in both cut and uncut forest patches. Beginning with the first step, place the steps in sequence for an investigation of the nesting birds using the scientific method. First step of investigation End of investigation Answer Bank Determine whether more birds nest in cut or uncut forest patches and share this conclusion with other researchers. Compare the data collected concerning nests from cut and uncut patches of forest. Observe birds nesting in cut patches and uncut patches of forest. Identify several patches of cut forest and several patches of uncut forest and decide how to conduct nest counts in them. Count the number of nests found and record the data. Hypothesize that more birds nest in cut forest patches.
