species diversity in different ecosystem slideshare

These differences are due to differences in the combination of genes. For example, in the species of human beings, each human shows a lot of diversity in comparison to another human. Species Diversity • The number and variety of life forms present in a biological community • About 8.7 million organism in our diversity Species Richness – is the number of different kinds of species in a particular are. Biological diversity is a key concept in the life sciences and plays a fundamental role in many ecological and evolutionary processes. species diversity, functional diversity, and ecosystem functioning 203 across a range of species richness from 1 to 32 (Fig. Option C: Biodiversity in 2000b). Clipping is a handy way to collect important slides you want to go back to later. Clipping is a handy way to collect important slides you want to go back to later. Biological diversity, abbreviated as Biodiversity, represent the sum total of various life forms such as unicellular and multi cellular organisms at various biological levels. 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.

Conservation of habitat diversity usually leads to the conservation of species and genetic diversity… Species diversity and; Community or Ecosystem diversity . Species diversity is best describe as a combination of richness and evenness. Fig. Now customize the name of a clipboard to store your clips. 1. Glossary; Whittaker (1972) described three terms for measuring biodiversity over spatial scales: alpha, beta, and gamma diversity.

Type of biodiversity 1. We here review research on speciation in freshwater fishes in light of speciation theory, and place this in a context of broad-scale diversity patterns in freshwater fishes. 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. Genetic diversity B. Individuals that belong to the same species are able to mate and produce offspring that are fertile. 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. You can change your ad preferences anytime. The term differs from biodiversity, which refers to variation in species rather than ecosystems. 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. Main Difference – Genetic Diversity vs Species Diversity. Species evenness: Relative abundance of in… Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Biodiversity most oftenrefers to the number of species in a certain area, or the species diversity. more sciencebitz resources on iTunesU and iBooks https://itunesu.itunes.apple.com/enroll/DEZ-HWS-HNJ https://itun.es/gb/ymzI6.n. Tropical areas have greater species richness as the environment is conducive for a large number of species 2. 5. Herbivores strongly influence plant communities and ecosystem processes in a variety of habitats, often changing vegetation composition, species diversity and productivity (Milchunas, Sala & Lauenroth 1988; McNaughton et al. For example, there is a large region of dry forest and savanna in Brazil known as the Cerrado (see Figure Cerrado Forest).

Genetic Diversity, Species Diversity & Ecosystem Diversity are types of Biodiversity.Biodiversity is of mainly three types which are above mentioned. Sixteen sites of Bhitarkanika mangrove areas were surveyed for the collection of roots and soil samples. Hundreds of studies spanning terrestrial, aquatic, and marine ecosystems show that high-diversity mixtures are approximately twice as productive as monocultures of the same species and that this difference increases through time. It is the degree of variation of life forms within a ecosystem or Biome or entire planet called BIODIVERSITY. The variety of life forms of a particular area are referred to as biodiversity. The name of an ecosystem doesn't automatically imply that all the species in that ecosystem are the same everywhere in the world. Species richness is a term which is used to measure the biodiversity of a given site. Seedlings of mangrove species were tested for AM colonization through root clearing and staining technique. 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. The good climate with good physical geography supports a better species diversity. • It is the variety of different habitats/ecosystems in a particular area (e.g.. wetland, woodland, grassland).
