It is the degree of variation of life forms within a ecosystem or Biome or entire planet called BIODIVERSITY. • What is biodiversity ? Tropical areas have greater species richness as the environment is conducive for a large number of species 2. The Definitive Guide to Diversity Types in the Workplace in 2020 [updated October 2020] This is the ultimate guide to Diversity Types in the Workplace in 2020.The same guide can be applied to the society, community about all aspects of diversity.The guide I will cover: Glossary; Whittaker (1972) described three terms for measuring biodiversity over spatial scales: alpha, beta, and gamma diversity. Ecosystem Biodiversity is further divided into three parts i) Alpha Biodiversity, ii) Beta Biodiversity iii) Gamma Biodiversity Biodiversity is the variety and variability among living organisms and the ecological complexes on the planet. Components of species diversity: species richness and relative abundance. Example Animals cannot synthesis their food directly but depend on the plants either directly or indirectly. Fig. However, no theories predict the conditions under which different relationships between species diversity and genetic diversity might arise and therefore when one level of diversity may be predicted using the other. Biology 120 lectures for 2nd exam 2012 2012, Traditional versus Modern Biotechnology (Exam 2 coverage), No public clipboards found for this slide. Option C: Biodiversity in Ecosystems Habitat Diversity The range of different habitats in an ecosystem, community or biome associated with the variety of niches that may be exploited by different species. Genetic Diversity. Since each species work in many different ways to contribute to a healthy ecosystem, having flaws or a dwindle in species diversity can have serious repercussion to the environment. the number of different species ; the relative numbers of individuals of each species. Type of biodiversity 1. Species richness:Number of different species present in an ecosystem. •Where is biodiversity greatest . Species diversity is a major determinant of ecosystem productivity, stability, invasibility, and nutrient dynamics. Clipping is a handy way to collect important slides you want to go back to later. Species diversity and genetic diversity may be correlated as a result of processes acting in parallel at the two levels. Individuals that belong to the same species are able to mate and produce offspring that are fertile. There are two constituents of species diversity: 1. For example, in the species of human beings, each human shows a lot of diversity in comparison to another human. Genetic diversity is the variation in the genetic composition of individuals in a population, community or species • Evolves as a result of many different processes: e.g. Ecosystem diversity involves different part of ecosystem like niches, trophic levels, energy flow, food chain and recycling of nutrients. SPECIES DIVERSITY - number or variety of species in a particular region. 2000b). For example, there is a large region of dry forest and savanna in Brazil known as the Cerrado (see Figure Cerrado Forest). •What is biodiversity ? Clipping is a handy way to collect important slides you want to go back to later. Species diversity and; Community or Ecosystem diversity . Species Ecosystem diversity is the effective number of different species that are represented in a collection of individuals diversity refers to the diversity of a place at the level of ecosystems. When we consider ecosystems, diversity is sometimes used to mean how may different species there are in a community. more sciencebitz resources on iTunesU and iBooks https://itunesu.itunes.apple.com/enroll/DEZ-HWS-HNJ https://itun.es/gb/ymzI6.n. •Why is biodiversity important? A study was carried out to assess the species diversity of arbuscular mycorrhizal (AM) fungi in different salinity zones of Bhitarkanika mangroves of Orissa, India.

Species evenness: Relative abundance of in… Functional diversity, which is a subset of this, is measured by the values and range in the values, for the species present in an ecosystem, of those organismal traits that influence one or more aspects of the functioning of an ecosystem. Main Difference – Genetic Diversity vs Species Diversity. Species diversity - number of different species that are represented in a given community (a dataset) -incorporates both the number of species in a community (species richness)and the evenness of species‘ abundances. The extraordinary species richness of freshwater fishes has attracted much research on mechanisms and modes of speciation.
