  3. Microbial Diversity 329: Organization Where, When: Thursdays, 4:00 - 5:15PM, Marley 341H Course Website: http://ag.arizona.edu/PLP/courses/plp329/microbial_diversity.html Grading: Midterm: take-home essay Final: take-home essay

  4. Why study biodiversity? 1. Humans altering/degrading environment at accelerating rate. 2. New uses of biodiversity for reducing suffering & environmental destruction. 3. Much diversity being lost through extinction. If estimate 5 million spp., then can calculate rate at ~17,500 spp. / yr.

  5. Estimates of biodiversity Kingdom/Major Division No. described species Viruses 1,000 Monera Bacteria, Myxoplasma, Cyanophycota 4,760 Fungi Zygomycota, Ascomycota, etc. 46,983 Algae 26,900 Plantae 248,428 Protozoa 30,800 Animalia (including Arthropoda) 989,761 Chordata (Tunicata, Vertebrata, etc.) 43,852 Total 1,392,485 Estimates of total diversity between 5-30 million species!!!! (E.O. Wilson, The Current State of Biological Diversity, Nat. Acad. Sciences, 1988)

  6. 750,000 250,000 41,000

  7. Why biodiversity important? Knowledge of biodiversity will mean little to most humans. Depend completely on < 1% living spp. for our existence. Rest untested fallow. Myers (1984) est. utilize ~ 7,000 kinds of plants for food. > 75,000 edible plants in existence. Barely touched upon organisms that are beneficial for: Pharmaceuticals Fibers Petroleum substitutes Pest and disease controls

  8. Goals of course 1. Introduce diversity of prokaryotes, eukaryotes, and viruses. 2. Discuss microbial phylogeny/taxonomy. 3. Expose students to wide range of research at The University of Arizona.
