  • 1. Science ModuleBiodiversity and Taxonomy
  • 2. From the beginningWhat is a species?
  • 3. There are multiple definitions.2 useful ones for our purposes...A set of organisms adapted to aparticular set of resources in theenvironment
  • 4. There are multiple definitions.2 useful ones for our purposes...A group of organismsthat share a lineage,and thus, genes atsome significant level
  • 5. Keeping trackThere are many many species to name
  • 6. Keeping trackHow do we organizeour species?
  • 7. Keeping trackBiologists use a system calledTaxonomy
  • 8. Keeping trackThe science of naming andclassifying species in an orderedsystem that indicates naturalrelationships
  • 9. Taxonomy assigns each animal ina hierarchical classification systemFirst, identify a new speciesSecond, determine if the species already has a nameThird, assign a new, unused, name to the speciesFourth, notify a name authority of the new speciesA system founded on the principles of Carl Linnaeus
  • 10. Taxonomy Gives order to a system of namesKingdom Animalia   Phylum    Arthropoda      Class       Insecta         Order          Insecta            Family             Lycaenidae              Genus               Maculinea                 Species               M. alcon (Denis & Schiffermüller, 1775)                                            
  • 11. Beyond speciesWhat is a biodiversity?
  • 12. Genes Species Ecosystems
  • 13. BiodiversityWe have documented ~2 millionspecies
  • 14. Biodiversity10-50 million are thought to exist
  • 15. Future of biodiversityWhat does biodiversity do for us?
  • 16. Why do scientists study biodiversity
  • 17. An attempt to get big pictureunderstanding of what is happeningto our natural world
  • 18. Conservation
  • 19. Ecosystem functions and services
  • 20. Evolution and natural selection
  • 21. Global and regional change
  • 22. Future of biodiversityWhat is happening to biodiversity?
  • 23. First, think about thisQuadrillion ants in the worldEO Wilson
  • 24. First, think about thisExtinction rates are 100-1000times higher than beforehumansIUCN, 2004
  • 25. Future of biodiversity"There is medium confidence thatapproximately 20-30% of species assessed sofar are likely to be at increased if increases inglobal average warming exceed 1.5-2.5 deg C(relative to 1980-1999). As global averagetemperature increase exceeds about 3.5 deg C,model projections suggest significantextinctions (40-70% of species assessed)around the globe." IPCC Four
