  1. Freshwater By Brian Broderick & Emily Majsak

  2. Alpine 9” 24°F Tropical Forest 24-93” 77°F Tropical Grassland 29-66” 68°F Desert 2-9” 64°F Temperate Grassland 10-30” 50°F Deciduous Forest 29” 48°F Coniferous Forest 18” 33°F Tundra 7” 19°F Climate • Precipitation and temperature vary with freshwater’s location

  3. Global Distribution

  4. Regional Variations • Standing water – lakes, ponds • Moving water – rivers, deltas • Wetlands – floodplains, mangrove swamps, bogs, marshes

  5. Resources • Medicine • Specie habitats (40% species, 12% animal species) • Food (rice, sago palm) • Drinking water • Fuelwood • Fibers (paper, clothing) • Flood control

  6. Changes Throughout Geologic Time • Where Glaciers used to be, now we’ve got lakes and rivers • ‘Older’, more nutrient rich = Eutrophic • ‘Middle Aged’, medium amount of • nutrients = Mesotrophic • ‘Younger’, less nutrients = Oligotrophic • Lakes haven’t changed much, per say

  7. Freshwater creates a hyptonic evironment Unique Plant & Animal Adaptations

  8. Threats • Direct Changes – strictly human, filling, grading, removal of vegetation, construction, changes in water levels and drainage patterns • Indirect Changes – natural changes, influx of surface water and sediments, fragmentation of a wetland, loss of recharge area, changes in drainage patterns
