Low scores (close to 0) indicate low diversity. Activity 2: Species Richness and Evenness Recently, this index has fallen out of favor because it doesn’t take into account habitat specific parameters required by specific species. A worksheet to designed to help scaffold calculating the AQA species diversity index. Activity 1: Biodiversity Discussion. This index combines measures of species richness and species evenness. This is … diversity index (H) accounts for species abundance by calculating the proportion of individuals of each species compared to the total number of individuals in the community (P i). It is therefore important to ascertain which index has actually been used in any comparative studies of diversity. A rather more scientific method of selecting a diversity index is on the basis of whether it fulfils certain functions or criteria. Before looking at Simpson's Diversity Index in more detail, it is important to understand the basic concepts outlined below. Quickly find that inspire student learning.

Species number and relative abundance affect the diversity of a community. For Location A: = 1 - 608 = 1 - 608 = 1 – 0.337 = 0.663 43 x 42 1806 . Any values above 0.5 usually indicate a relatively diverse population. Index Of Diversity - Displaying top 8 worksheets found for this concept..

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. You could not and no-one else going like ebook stock or library or borrowing from your friends to approach them. 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. Simpson’s Diversity Index . Calculate Simpson's index for the community pictured below: . Before looking at Simpson's Diversity Index in more detail, it is important to understand the basic concepts. Simpson's Index of Diversity (1-D) Simpson's Reciprocal Index (1/D) Simpson's Index (D) Uses the relative abundance of different species Gives probability that any 2 individuals drawn at random from a large community belong to a different species Need: number of different species and number of times each was found . It takes into account the number of species present, as well as the abundance of each species. Many diversity indices have been developed to combine different measures of biodiversity. Biodiversity provides an aesthetic value that humans find appealing. Compare the diversity of these two kinds of mixed nuts. For Location B: = 1 - 520 = 1 - 520 = 1 – 0.241 = 0.759 47 x 46 2162 . The calculation is based on the number species in an area, dependent upon richness (number of unique species) and abundance (number of individual species). The range is from 0 to 1, where: High scores (close to 1) indicate high diversity. Download the worksheet. The value of will always fall between 0 and 1, where 1 represents complete diversity and 0 represents complete uniformity. 1. For example, a healthy forest or woodland should have a diversity index of 0.7. Enter the data in this Simpson index calculator and click calculate. Calculating Simpsons Index of Biodiversity Exercise - A-level Biology . The samples are those used in the previous worksheet (Similarity and Dissimilarity) ? 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. Can you point out any problems in these assumptions? This is because diversity is usually proportional to the stability of the ecosystem: the greater the diversity, the greater the stability. After being led through a derivation of Simpson’s Diversity Index, students then apply the equation to a data set on their own. 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. Displaying top 8 worksheets found for - Index Of Biodiversity. Indices of Diversity. Use the Simpson’s diversity index to determine which of the following three communities of 100 individuals is most diverse. The single spreadsheet gives the calculation for Simpson?s Index (D) and Shannon-Weiner (H?) 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.

This activity asks students to sort seashells and calculate the Simpson’s biodiversity index. n = the total number of organisms of a particular species: N = the total number of organisms of all species . At the end, stu-dents may discuss whether their results support their original hypotheses. The range is from 0 to 1, where: High scores (close to 1) indicate high diversity. Simpson’s Diversity Index Another measure of diversity is based on the probability that any two elements selected at random will belong to the same category, i.e. In ecology, it is often used to quantify the biodiversity of a habitat. 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. 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. diversity index values will vary between 0, which would indicate no diversity, and 1, which is very diverse.
