Intro to biodiversity and taxonomy
- 1. Science Module Biodiversity and Taxonomy
- 2. From the beginning What is a species?
- 3. There are multiple definitions. 2 useful ones for our purposes... A set of organisms adapted to a particular set of resources in the environment
- 4. There are multiple definitions. 2 useful ones for our purposes... A group of organisms that share a lineage, and thus, genes at some significant level
- 5. Keeping track There are many many species to name
- 6. Keeping track How do we organize our species?
- 7. Keeping track Biologists use a system called Taxonomy
- 8. Keeping track The science of naming and classifying species in an ordered system that indicates natural relationships
- 9. Taxonomy assigns each animal in a hierarchical classification system First, identify a new species Second, determine if the species already has a name Third, assign a new, unused, name to the species Fourth, notify a name authority of the new species A system founded on the principles of Carl Linnaeus
- 10. Taxonomy Gives order to a system of names Kingdom Animalia Phylum Arthropoda Class Insecta Order Insecta Family Lycaenidae Genus Maculinea Species M. alcon (Denis & Schiffermüller, 1775)
- 11. Taxonomy Gives order to a system of names Kingdom Animalia Phylum Arthropoda Class Insecta Order Insecta Family Lycaenidae Genus Maculinea Species M. alcon (Denis & Schiffermüller, 1775) Genus
- 12. Taxonomy Gives order to a system of names Kingdom Animalia Phylum Arthropoda Class Insecta Order Insecta Family Lycaenidae Genus Maculinea Species M. alcon (Denis & Schiffermüller, 1775) Genus Species
- 13. Taxonomy Gives order to a system of names Kingdom Animalia Phylum Arthropoda Class Insecta Binomial Order Insecta Family Lycaenidae Genus Maculinea Species M. alcon (Denis & Schiffermüller, 1775) Genus Species
- 14. Beyond species What is a biodiversity?
- 15. Genes Species Ecosystems
- 16. Biodiversity We have documented ~2 million species
- 17. Biodiversity 10-50 million are thought to exist
- 19. Future of biodiversity What does biodiversity do for us?
- 23. Why do scientists study biodiversity
- 24. An attempt to get big picture understanding of what is happening to our natural world
- 25. Conservation
- 26. Ecosystem functions and services
- 27. Evolution and natural selection
- 28. Global and regional change
- 29. Future of biodiversity What is happening to biodiversity?
- 30. First, think about this Quadrillion ants in the world EO Wilson
- 31. First, think about this Extinction rates are 100-1000 times higher than before humans IUCN, 2004
- 32. Future of biodiversity "There is medium confidence that approximately 20-30% of species assessed so far are likely to be at increased if increases in global average warming exceed 1.5-2.5 deg C (relative to 1980-1999). As global average temperature increase exceeds about 3.5 deg C, model projections suggest significant extinctions (40-70% of species assessed) around the globe." IPCC Four
