Definition of Genetic Diversity Genetic diversity is the diversity or variability within species… Other measures of biodiversity include genetic diversity (the variety of a specific organism’s genes), and ecosystem diversity (the number of different ecosystems found within a particular area). The proposed index incorporates an importance weight to each species of organisms found in an ecosystem. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. Differentiate between species diversity and ecological diversity. Some ecologists view diversity indices with suspicion, questioning whether they are biologically meaningful. This species often feeds on the ground; therefore, the greater species richness in the undergrowth is an important component of its occurrence. 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. Genetic diversity B. The distribution and number of species in an area are referred to as species diversity whereas ecological diversity describes the diversity at the ecosystem level. It is both a property of the living and an essential condition for its survival. Essentially, by having greater genetic diversity within a fish species (e.g., many discrete populations with different life history strategies rather than a single homogenized population), the species is more apt to withstand variable conditions. A species does not necessarily need to be genetically diverse to thrive, if it lives under exactly the right conditions. Species diversity is a measurement of biological diversity to be found in a specific ecological community. A.9. If a fire tears through a forest where only one species exists and is wiped out by the fire, the forest ecosystem is less likely to deal with this loss than if only one out of 20 species disappeared. When discussing the influence of rare species, it is important to consider how rarity is defined because definitions vary across studies and conservation strategies. Australia is renowned for its globally distinct ecosystems, made up of diverse flora and fauna. ... explain the importance of random sampling in determining the biodiversity of an area . Genetic diversity is one alternate concept of biodiversity. Species diversity takes into consideration species richness, which is the total number of different species in a community. The importance weights are derived 1* Mahantesh Kamatyanatti, 2 Shailesh Kumar Singh and 3 Bhallan Singh Sekhon . Others, such as salt flats or a polluted stream, have fewer. Species diversity. ( 2006 ) showed that stand structure and shrub and herb coverage were essential habitat variables for hazel grouse occurrence in … Healthy ecosystems and rich biodiversity: Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. Importance of species diversity, pollination and . Gustav Paulay in 2003 described the marine species diversity of Guam, some 1,200 km from Palau with a relatively complete listing, providing a “nearby” geographic comparison to Palau. It also takes into account evenness, which is the variation of abundance in individuals per species in a community. It is very important as the genes of any population are quite essential. Recent studies have shown that plant genetic diversity can be important for ecosystem functioning and in some cases its effects are compara-ble in magnitude to the effects of species diversity (Crutsinger et al., Importance of biodiversity for health research and traditional medicine. Q.9. Our biodiversity is very important to the well-being of our planet. Many species, such as insects, remain largely undiscovered. With between 3 and 30 million species on earth, here are the reasons why they are important. Each species has a role in the ecosystem.
