Presentation Transcript

  1. Apes 5/7/18 Take out your ld50 lab and toxins organizer With a group of 2-3: what math and concept issues did you have with this lab?

  2. Aquatic biome examples

  3. Freshwater: wetlands • Everglades • Also contains Mangrove, Salt Marsh/Estuarine, among other biomes

  4. Marine: salt marshes • Coastal, grassy wetlands that get flooded with ocean water • Part of estuaries • Upper intertidal zone • Chesapeake Bay, Mississippi River Delta

  5. Marine: mangrove swamps • Coastal wetlands full of specialized trees • Florida mangrove forest

  6. Marine: intertidal zones • Where would we find our mangroves and salt marshes on this diagram?

  7. Case studies to read, if interested • Page 55 (Everglades) • Page 64 (Mono Lake, CA) • Page 481 (Chesapeake Bay) • Page 293 (Klamath River) Just Remember… Habitat destruction Invasive species Pollution Population Climate change Overexploitation It applies to everything!

  8. Biomes card game

  9. 2018 Hot Topics • Drought (i.e. California, with El Nino) • El Nino • Hurricanes (related to climate change) • Flint, Michigan • Keystone XL Pipeline • Experimental Design – see 2012 FRQ, #3, for an example • BPA/Endocrine disruptors • Palm Oil • Thawing permafrost/change in albedo • Wind power with calculations See my SWIFT site for a complete list

  10. Due Wednesday • All stamps! • Major Laws Quiz
