- 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…Draw a species accumulation curve for the beetles in Area C3, based on the data shown in Table 2. Ensure that you calculate a standard deviation around each average number of species per sample; plot this on this figure. Make sure you label the axes and that you provide a legend. You will need to reassemble the samples in all possible combinations in order to derive the species area curve(Table provided)One of the challenges faced by organisms as the climate changes is the changes observed in phenology. Describe what a change in phenology would be as a result of climate change by giving me an example of it occurring to some organisms (you can make up the organisms in the example). How would a change in phenology result in a population going extinct (possibly because of a trophic mismatch)?

Concept Mapping activity, you will revise your concept map on sea otters from the beginning of the semester based on your new understanding and comprehension of traditional ecological knowledge. Based on the videos, your map should describe the relationships between sea otters, shellfish (like clams), and people. Consider including some of the following terms as you map these relationships: Butter clams Western knowledge systems Indigenous knowledge systems Management barriers Customary and traditional foods Colonial assumptions and methodologiesRead this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.
- Write a 2 page (minimum) report on an organism of your choice and its ecological relevance. Minimum of 2 peer-reviewed journal articles as sources for the information contained in your writing. Considerations for content: - adaptations, morphologies, or behaviors that are specific to your organism - taxonomic classification - how is your organism affected by abiotic factors (non-living things) - how is your organism affected by biotic factors (living thing) - what is the habitat range of your organism - describe the life history of your organism and make it relevant - if your organism went extinct, what would be the resultant effectThe following is a matching question, below is text interepreted.Match each term to the best definition or description. ResiliencySpecies richnessBiodiversityGamma diversity words to match it with: number of species in an environment, considers number of habitats and total species number among them, combination of species richness and species eveness, same as species eveness, high probability of recovery to original state, high probability of disruption.If you do not understand the text based question, use the image below.You're analyzing biodiversity on three islands: Island A, located near the equator with varied elevations; Island B, situated in temperate latitudes and relatively flat; Island C, another equatorial island but with a wide variety of habitats. To test your answers to the first question, you decide to survey the lizard species on the islands. Below is a graphical representation of a survey plot from each island, where icons represents different species and the abundance of each species is tallied in the table below. (note: these surveys may not represent the entire island patterns, so don’t use these to try to answer the first question!) A. What is the alpha diversity on each island? Island A Island B Island C B. What is the beta diversity between each island pair (A-B, A-C, B-C)? Beta diversity A-B Beta diversity A-C Beta diversity B-C C. Calculate the Shannon-Weiner index and Simpson’s index of diversity for each island. Island A Island B Island C D. What do these diversity…
- Two species of bird live in the same tree. Seeds only grow at the tops of the tree and insects only live at the bottom of the tree. Bird species A lives in the tops of the trees and eats both insects and seeds. Bird species B lives in the bottom of the tree and only eats insects. Which of the following describes why these two species live together in the same community? Group of answer choices Species A and Species B have the same fundamental niche. Species A and Species B have the same realized niche. Species A and Species B have a different fundamental niche. Species A and Species B have a different realized niche.When we measure species density. If you apply random sampling and systematic sampling to a site setting, what problems may we encounter? Why is there an error compared with the actual density of species?To understand the biodiversity of insects in different sites around their community, students performed a leaf litter lab where leaf litter was collected from two sites: one from beneath the trees in an organically managed, commercial landscape established one year ago and one from beneath the trees in a nearby nature preserve that have not been trimmed or managed in over twenty years. The students hypothesized that there would be more insect biodiversity in the leaf litter at the nature preserve than at the managed site. The leaf litter from each site was placed into a funnel with a light shone on the top to drive any insects out of the litter. Species were collected in an alcohol-filled container below the funnel, and the species were identified using magnifying lenses and a key. (j) Explain how modifying the experiment to collect samples from wet and dry sites could alter the results of the experiment.
