It means understanding that each individual is unique, & recognizing our individual differences.
Diversity indices provide more information about community composition than simply species richness (i.e., the number of species present); they also take the relative abundances of different species into account.Diversity indices provide important information about rarity and commonness of species in a community. Species diversity if influenced by species richness and by species evenness. Citing Literature. 14. SPECIES EVENNESS stock markets, air pollution, etc. It takes into account the number of species present, as well as the abundance of each species. What exactly is diversity?

In a nutshell, it’s about empowering people by respecting and appreciating what makes them different, in terms of age, gender, ethnicity, religion, disability, sexual orientation, education, and national origin. Alternatively, species diversity indices have now been transposed to functional diversity measurements, and several new indices have been proposed (e.g., Mason et al.

. Diversity indices • To get a better description of the community we need to get a measure of spp richness and evenness of their distribution • We usually use an index to represent several different measures – E.g. simply my objective is to see if there are special and temporal differences in phytoplankton diversity among 8 sampling stations.

Using this formula, the higher the result (D), the greater the species diversity. These results are attributed to the greater dominance of the palm species Euterpe edulis Mart.

Introduction: A diversity index is a mathematical measure of species diversity in a community. The resultant diversity indices are a key feature of communities which can throw light on many aspects of conservation. It is assessed through a variety of indices, such as functional evenness and functional divergence that have been found to be better predictors of ecosystem functioning than species richness (Gagic et al., 2015).

Over 60 indices are used in ecology to measure biodiversity. - only residents are counted - treats common and rare species with the same weight Species diversity When comparing communities that are similar, low diversity could be indicative of pollution, eutrophication or recent colonization of a site. Retrieved from work.chron.com. The Index of Diversity which AS/A2 level students in the UK need to understand can be found here. Introduction; 2. • Comprises two components • Species Richness: the number of species in an ecosystem. Sustainable architecture is architecture that seeks to minimize the negative environmental impact of buildings by efficiency and moderation in the use of materials, energy, development space and the ecosystem at large. 1. Simpson's Diversity Index is a measure of diversity. Sections . If you continue browsing the site, you agree to the use of cookies on this website. Looks like you’ve clipped this slide to already. Most research that considers the impact of diversity on an energy system employs the Shannon diversity index, sometimes referred to as the Shannon–Wiener index [1] , [19] , [32] . Loading .. … Published in: Education. Mathematical measurement to define community composition (number of species) and commonness of species in a community H = -∑pi lnpi The article presents a brief overview of the commonest indices used in ecological studies. • Species Richness -the number of species that live in a certain location. nest shape). Nonetheless, species diversity indices can be applied to categorical traits (using trait levels instead of species) in order to describe functional richness and equitability. Indices are used to measure proportional abundance. RESPONSE INDICATORS 50 6.1 Actions from the public sector 50 6.2 Actions from the private sector 51 7. Simpson’s Index (D): Simpson’s index measures the probability that any two individuals drawn at random from an infinitely large community will belong to same species. Simpson’s Diversity Indices: The term “Simpson’s diversity index” can actually refer to any one of 3 closely related indices. A step by step method for calculation of species diversity, species richness, species evenness and similarity and dissimilarity indices. Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the built environment. I introduce two of these diversity indices, the Shannon Index and the Simpson's Index, in the slideshows I have included here. Les diversity managers prennent leurs distances avec les politiques anti-discriminatoires classiques et remettent le marché au cœur de la problématique d’intégration en posant comme postulat l’idée d’une convergence entre les intérêts du monde des affaires et ceux des minorités. Diversity : an introduction- Definition, types and factors. Multiculturalism & Social Diversity in the Criminal Justice System. Functional diversity measures the number or diversity of functionally disparate species or properties of a community. Communities can be described and compared through the use of diversity indices. γ diversity : diversity of the whole landscape. Presentation on the definition of diversity, identifying diversity, and acknowledging the benefits of diversity. Diversity Indices • Usually used as biodiversity (as in species), but can apply to other data where you count the number of times a particular category occurs (e.g. SPECIES RICHNESS 0 From Embeds. Diversity Powerpoint 1. The Hutcheson's t test showed no significant difference between both areas' Shannon diversity indices (t: -1.04; p: 0.30). Upcoming SlideShare. Species diversity in communities is a product of two variables: the number of species (richness) and their relative proportions (evenness). Material and methods; 3. On SlideShare. Presented By: Katina Lane-Fomby Global Diversity and Inclusion Manager 3M Corporation . simply my objective is to see if there are special and temporal differences in phytoplankton diversity among 8 sampling stations. See our User Agreement and Privacy Policy. Diversity magnifies the power of a general education by helping to liberate you from the tunnel vision of an ethnocentric and egocentric viewpoint. Diversity indices have been developed to measure diversity in various fields, including biology, ecological sciences, information theory, statistics, and economics . - a count of species, and it does not take into account the abundances of the species or their relative abundance distributions. To get a better description of the community we need to get a measure of species richness and evenness of their distribution. Acknowledgments. i calculate both indices and i would like to discuss the results. The DDI and FS 24hr showed an association with MAR if the two locations were combined together. David Weedmark. University of Massachusetts Lowel. Recovered from slideshare.net. The entities of interest are usually individual plants or animals, and the measure of abundance can be, for example, number of individuals, biomass or coverage. Diversity is any dimension that can be used to differentiate groups and people from one another. By moving beyond yourself, you gain a panoramic perspective of the world around you and a more complete view of your place in it. When diversity indices are used in ecology, the types of interest are usually species, but they can also be other categories, such as genera, families, functional types or haplotypes. … There are many versions of diversity indices, but students are only expected to be able to apply and evaluate the result of the Simpson diversity index as shown below. i calculate both indices and i would like to discuss the results. 1. 5.4.1 Remotely sensed vegetation indices 46 5.4.2 Living Planet Index 48 5.4.3 The IUCN Red Lists and Red List Indices 48 5.4.4 Farmland bird indices 49 6.
