  2. Limnology rivers, and streams Ecology of freshwaters Lakes, rivers, and streams Lakes are born by catastrophe age , and quietly die

  3. Limnology Rivers are ancient Rivers carry sediment

  4. Limnology Rivers are ancient Rivers carry sediment meander

  5. Limnology A river creates its valley Rivers are ancient Rivers carry sediment meander

  6. Limnology Estuaries

  7. CO2 + water sugars Limnology Lakes & rivers differ in food chains Lakes support photosynthetic chains phytoplankton Energy is autochthonous

  8. Limnology Lakes & rivers differ in food chains Rivers support a detritus food chain Energy is allochthonous

  9. Limnology in temperature Lakes are stratified a summer lake

  10. wind Limnology in temperature Lakes are stratified a summer lake epilimnion mixes hypolimnion stagnates

  11. Limnology Lakes are stratified by light a summer lake photosynthesis detritus decomposition nutrient rich sediment

  12. Limnology Lakes are stratified There are 2 lakes during warm a summer lake months productive epilimnion detritus food chain releasing nutrients phytoplankton starved for nutrients

  13. wind Limnology In the fall surface water cools 40 C water sinks phytoplankton blooms fall turnover nutrients returned to epilimnion

  14. wind Limnology In the fall surface water cools 40 C water sinks phytoplankton blooms fall turnover nutrients returned to epilimnion

  15. ice Limnology In the winter lake is sealed

  16. wind Limnology In the spring spring turnover nutrients mixed into epilimnion phytoplankton bloom

  17. Limnology Lake food chain nekton zooplankton phytoplankton

  18. Limnology Zooplankton migration

  19. Limnology The Lake as a Microcosm -- Steven J. Forbes

  20. Limnology An ecosystem united seasonally
