Presentation Transcript

  1. Limnology: Study of Freshwater Systems • New science, since 1850 • Phytoplanktons dominate • Diatoms—1/4 of all plants, >70,000 spp. • Macrophytes • submerged • emergent

  2. Lake productivity: • Closed systems, nutrient sinks • CO2 and O2 from air and water • Autochthonous inputs • Allochthonous inputs

  3. OligotrophicEutrophic • Hypo > Epilimnion Hypo < Epilimnion < allochthonous > allochthonous < decay in benthic > decay in benthic O2 > depth O2 < depth • low productivity high productivity

  4. Lake factors: • Geography/topography • Nutrient sources • Size • Age

  5. Stream Ecology
