  1. Biogeography Arizona Geography GCU 221

  2. Game Plan: • Ecosystems • Adaptations and Niches • Ecotones • Major Ecosystems of Arizona

  3. 1. Ecosystem A system formed by the interaction of a community of organisms with their physical environment. • Variety of interrelated organisms (food web) • Environment • Adaptations

  4. 1. Ecosystem

  5. 1. Ecosystem • Sun – powered by nuclear energy • Plants – powered by the sun • Herbivores – powered by plants • Omnivores – powered by plants and animals • Carnivores – powered by animals • Climax Species – powered by big animals • Decomposers – powered by dead things Arizona Activity…

  6. 1. Columbian Exchange: Ecosystem in Flux

  7. 1. Different Environments: more urban

  8. 1. Different Environments: warmer planet

  9. 1. Adaptations and Niches

  10. 1. Biodiversity: good or bad • Medea or Gaia

  11. 1. Medea: Blue Fin Tuna

  12. 1. Gaia: Platypus

  13. 2. Ecotones • Boundaries between ecosystems • High biodiversity

  14. 3. Arizona Major Ecosystems • Tundra: San Francisco Peaks • Spruce Fir: White Mountains • Ponderosa Pine and Gamble Oak: Mogollon Rim • Pinyon – Juniper: Sedona • Grassland: Sunset Point • Cottonwood and Willow: Verde River • Sonora Desert: Superstition Mountains • Colorado Desert: Yuma

  27. Things to know: • What is an Ecosystem? • What is the Columbian Exchange • What does it mean to be Gaian? What does it mean to be Medean? • What is an Ecotone and why are they important? • Basic understanding of the 8 major ecosystems of the Arizona (which is hotter or colder, where plant and animal species are common, like Cottonwood or Antelope) Help: Ask Dr. Douglass
