Name:_____ Biodiversity Worksheet Part I: Calculate the species richness (R), Shannon-Weiner (H), and Simpson (D) Index of Biodiversity for each of the following communities. 1. Recently, this index has fallen out of favor because it doesn’t take into account habitat specific parameters required by specific species. Use the Simpson’s diversity index to determine which of the following three communities of 100 individuals is most diverse. Simpson's Diversity Index: Measuring Biodiversity Maintaining biodiversity is important for a variety of reasons: Diverse communities are generally less susceptible to perturbation (disturbance) than similar but less diverse communities. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. A rather more scientific method of selecting a diversity index is on the basis of whether it fulfils certain functions or criteria. - Inverse Simpson index is the effective number of types that is obtained when the weighted arithmetic mean is used to quantify average proportional abundance of types in the dataset of interest. 1.1 What does biodiversity mean to you?

Simpson's Diversity Index is a measure of diversity. The name 'Simpson's Diversity Index' is often very loosely applied and all three related indices described above (Simpson's Index, Simpson's Index of Diversity and Simpson's Reciprocal Index) have been quoted under this blanket term, depending on author. Discuss in class. In ecology, it is often used to quantify the biodiversity of a habitat. It is therefore important to ascertain which index has actually been used in any comparative studies of diversity. Explain in one or two sentences what the numbers actually mean.

Historically, the index has been used to measure the effects of habitat quality such as effects of pollution effluents. Before looking at Simpson's Diversity Index in more detail, it is important to understand the basic concepts outlined below. View fullsize. In the Simpson index, p … Simpson’s diversity index (SDI) measures community diversity. Any values above 0.5 usually indicate a relatively diverse population. Indices of Diversity. Community 1 contains 10 species, with 91 individuals of the first species, and 1 individual of each of the remaining species. Simpson's Diversity Index is a measure of diversity which takes into account the number of species present, as well as the relative abundance of each species. For Location A: = 1 - 608 = 1 - 608 = 1 – 0.337 = 0.663 43 x 42 1806 . Species number and relative abundance affect the diversity of a community. Simpson's Index = 1 - [0 .1225 + 0.16 + 0.0625 ] Simpson's Index = 1 - [0.345] Simpson's Index = 0.655 Problems: Tables to organize the data needed to calculate Simpson's Index are found on the last page of this exercise. This is because diversity is usually proportional to the stability of the ecosystem: the greater the diversity, the greater the stability. Many diversity indices have been developed to combine different measures of biodiversity. February 6, 2017 Tom Whitburn. One is called the Simpson's Index. Ecologists, biologists who study the species in their environment, are interested in the diversity of species in the habitats they study. You could not and no-one else going like ebook stock or library or borrowing from your friends to approach them. ten species and their abundance. A diversity index (also called phylogenetic or Simpson's Diversity Index) is a quantitative measure that reflects how many different types (such as species) there are in a dataset (a community) and that can simultaneously take into account the phylogenetic relations among the individuals distributed among those types, such as richness, divergence or evenness. In this case, a few rare species with only a few representatives will not affect the diversity. We can use Simpson's index of diversity to quantify and compare the diversity of different communities. The samples are those used in the previous worksheet (Similarity and Dissimilarity) ? This activity asks students to sort seashells and calculate the Simpson’s biodiversity index. The range is from 0 to 1, where: High scores (close to 1) indicate high diversity. Low scores (close to 0) indicate low diversity.

At the end, stu-dents may discuss whether their results support their original hypotheses. - The Gini coefficient measures the inequality among values of a frequency distribution (for example levels of income). The Simpson diversity index is a quantitative measure that reflects how many different types are there in a dataset, and how evenly the basic entities are distributed among those types in the data set. Compare the diversity of these two kinds of mixed nuts. Can you point out any problems in these assumptions? n = the total number of organisms of a particular species: N = the total number of organisms of all species . A brief exercise using coral reef photographs and a fish identification chart to calculate a Simpsons Index of Biodiversity. As species richness and evenness increase, so diversity increases.

Simpson’s Diversity Index . The calculation is based on the number species in an area, dependent upon richness (number of unique species) and abundance (number of individual species). In ecology, it is often used to quantify the biodiversity of a habitat. For example, a healthy forest or woodland should have a diversity index of 0.7. This is … The Simpson Diversity Index ranges from 0 to 1. where n i is the number of observations from the sample in the i th of k (non-empty) categories, n is the sample size and p i = n i /n. Biological diversity can be quantified in many different ways. Quickly find that inspire student learning. A worksheet to designed to help scaffold calculating the AQA species diversity index. Simpson’s diversity index (SDI) measures community diversity. For this reason, Simpson’s index is usually expressed as its inverse (1/D) or its compliment (1-D) which is also known as the Gini-Simpson index. The value of D ranges between 0 and 1. Although it’s commonly used to measure biodiversity, it can also be used to gauge diversity differences in populations in schools, communities and other locations.
