Transcript

  • 1.   Various and Diverse types of life on Earth   One of the central themes of conservation   Measure of how healthy our ecosystems are   healthyecosystems support high biological diversity   stressed or highly disturbed ecosystems do not   3 main components or levels:   genetic level biodiversity   species richness biodiversity   ecosystem biodiversity
  • 2.  degree of variation in all the genes for all individuals within a species  geneticdivergence is the basis for evolution  Populations having greater genetic diversity are far better equipped to cope with environmental change
  • 3.   Banana  Lakatan, latundan, senyorita, saba, cavendish, etc   Rice  C4, malagkit, dinorado, intan, sinandomeng, tec
  • 4.   measure of the number of species which occur within a particular taxonomic level (i.e., genus level, family level, etc.) in a geographic area   speciesdiversity 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
  • 5.   collectionof all the plants and animals within a particular area, each differing in species composition, physical structure and function
  • 6.   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
  • 7.   ACTIVITY : CAR PARK   Reporting group   CHOOSE A CAR PARK AND OBTAIN THE FOLLOWING DATA   FOLLOWINGPAGE 45 OF WORKSHEET FILL-OUT THE NECESSARY INFORMATION   Prepare one-page report in an acetate   CHOOSEA REPRESENTATIVE AND REPORT YOUR RESULTS NEXT MEETING
  • 8.   PROPORTION (pi)   H’ = -Σpilogpi   Number/total   Get sum of your previously obtained value   Multiply with a negative   Log (pi) sign to obtain a positive   GetLOG using your value calculator   pilogpi   Multiply previously obtained value with your proportion
  • 9.   CAS CAR PARK   PGH/OPD CAR PARK   NEDA CAR PARK   PHARMACY/NURSING CAR PARK
