EXTENSION: Biodiversity has many components. "Relative abundance" is a measure of how abundant the members are for onespecific population when compared to all the living things in a community. The formula for this is:Relative Abundance (%) = [(# organisms in population of interest) / (total number of organisms in thecommunity)] x 100Given a 100 m² plot where the following species of grasses are present, calculate the relative abundance for species 4. Writeyour answer in the space below. Give your answer as a percentage. Round to the nearest whole number.Grass SpeciesNumber Present21048LO7%8%13 %16%7612215925275

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?

Another ecologist reported a diversity index value of 1.511 in a different community nearby the one you studied. This community is _ diverse than the one you calculated. Please see the attached image to get a better grasp of the question. How to Calculate Biodiversity and Ecology College Biology 2 Advanced Concepts Background Information In the Shannon index, p is the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), ln is the natural log, Σ is the sum of the calculations, and s is the number of species... Species Evenness Species evenness takes into account the number of species and the relative abundance of species in a community. Several indices have been proposed. Two of the commonly used measures of evenness are the Shannon index (H) and the Simpson index (D). Question 2: What is the Shannon diversity index value for this community? What is the species evenness for this community?
Biodiversity: Values & Threats 1. In terms of the number of species in various taxonomic groups, what types of organisms represent thegreatest diversity on our planet? And how do we know we’re not “done” cataloging all of life on earth? 2. When scientists try to estimate the number of species that actually exist on earth today, why is thefigure so variable? 3. Describe the global biodiversity patterns found in relation these parameters:Latitude Precipitation Elevation 4. In a well-crafted paragraph (5-7 descriptive sentences) specifically describe 4 key ways thatbiodiversity benefits mankind. Use examples to support each of your statements.
INTRODUCTION: Quadrat sampling is a classic tool for the study of ecology, especially biodiversity. In general, a series of squares (quadrats) of a set size are placed in a habitat of interest and the species within those quadrats are identified and recorded. QUESTION: What are the advantages and disadvantages of a quadrat sampling method?
Unit #5: Ecology and Evolution World’s average ecological footprint = 2.84 gha/person (world total: 20.1 billion gha used/year) World’s biocapacity = 1.73 gha/person (12.2 billion in total) What does this mean? Under what circumstances might investigators choose to do one type of analysis versus the other (mtDNA vs. Y chromosome DNA)?

nd biodiversity of sites in their own community, students performed a leaf litter lab where leaf litterwas collected from two sites: one from beneath the trees in an organically managed, commercial landscapeestablished one year ago and one from beneath the trees in a nearby nature preserve that have not been trimmed ormanaged in over twenty years. The students hypothesized that there would be more insect biodiversity in the leaflitter at the nature preserve than at the managed site. The leaf litter from each site was placed into a funnel with alight shone on the top to drive any insects out of the litter. Species were collected in an alcohol-filled containerbelow the funnel, and the species were identified using magnifying lenses and a key
