Biodiversity And Measurement

  Various and Diverse types of life on Earth

  One of the central themes of conservation

  Measure of how healthy our ecosystems are   healthy ecosystems support high biological diversity   stressed or highly disturbed ecosystems do not

  3 main components or levels:   genetic level biodiversity   species richness biodiversity   ecosystem biodiversity

 degree of variation in all the genes for all individuals within a species

 genetic divergence is the basis for evolution  Populations having greater genetic diversity

are far better equipped to cope with environmental change

 Banana  Lakatan, latundan, senyorita, saba, cavendish, etc

 Rice  C4, malagkit, dinorado, intan, sinandomeng, tec

 measure of the number of species which occur within a particular taxonomic level (i.e., genus level, family level, etc.) in a geographic area

 species diversity tends to increase along a longitudinal gradient  EXAMPLE : more species are being found toward

the Indo-Pacific region around north-eastern Australia, Indonesia and the Philippines

 collection of all the plants and animals within a particular area, each differing in species composition, physical structure and function

 Species Richness  Number of species in the community

 Species Evenness  Relative proportion of individuals belonging to each

of the species

 Species Diversity  Shannon-Weiner index
