Presentation Transcript


  1. UNDERC education and research programs • 35 lakes and bogs • 7 streams • many forest and wetland habitats Bergner Bay Long

  2. GLOBAL BIOMES • AQUATIC BIOMES • RIVERS • LAKES • WETLANDS • ESTUARIES • SALT MARSHES / MANGROVES • TIDAL ZONES • CORAL REEFS • OCEANS

  3. The Hydrologic Cycle • Over 71% of the earth’s surface is covered by water: • Oceans contain 97%. • Polar ice caps and glaciers contain 2%. • Freshwater in lakes, streams, and ground water make up less than 1%.

  4. Hydrologic cycle

  5. Zonation in the Littoral Areaand Shore Open water phytoplankton Shrub & Trees Mixed herbaceous Deep water emergents Grass stage Submerged plants Floating plants Shallow water emergents

  6. Vertical Zonation in Stratified Lakes Light Compensation Level Littoral zone Limnetic zone Profundal zone

  7. Horizontal Lake Zones and their Biological Communities psammon macrophytes benthos

  8. During Summer StratificationLakes Develop Distinct Layers Stratified layers may develop differences in both oxygen and temperature.

  9. Lake Zones in Relation to O2 and CO2 Littoral O2 Limnetic Sublittoral Profundal CO2 Epilimnion Metalimnion Hypolimnion

  10. Bergner Lake is “Oligotrophic”

  11. Late Successional Eutrophic Pond

  12. Aquatic (Hydrarch) Succession Oligotrophic Lake • Lake conditions • Littoral vegetation OR Bog conditions (raised peat bog, Sphagnum overstory) • Terrestrial habitat Mesotrophic to Eutrophic Lake Sphagnum Marsh (Eutrophic) Bog (Dystrophic) Terrestrial

  13. Dystrophic “Bog” Habitats are common at UNDERC lagg lagg peat open water false sediments

  14. Forest Service Bog one of many Dystrophic Lakes at UNDERC

  15. Crampton Lake

  16. Brown Lake

  17. River Continuum Concept

  18. Class projects - design data analysis

  19. Location:

  20. Peter Lake

  21. Carl Von Ende Sampling for Chaoborus at Ed’s Bog

  22. “Big Bag” (Mesocosm) Experiment

  23. Mesocosms in Peter Lake

  24. Long Long Lake divided Control of lake algae by regulating fishes Current Research at UNDERC (Focus on natural processes in undisturbed environments) • Biological indicators of water quality and environmental change • Biological regulation of aquatic productivity • Global environmental change • Aquatic-terrestrial habitat interactions • Naturally acidic aquatic environments • Biting arthropods and their transmitted diseases • Introduced crayfish

  25. NEON is coming!!!

  26. NEON’s Mission • The NEON mission is to : • discover and understand the fundamental ecological principles that govern the responses of the biosphere. • provide the capacity to forecast future states of ecological systems.

  27. NEON Climate Domains

  28. Drivers and Responses

  29. The changing landscape

  30. Class outline • Mon am - lake lecture • Mon am - field equipment demo • Mon pm - lake sampling • Mon pm - invert / zoop id • Tues am - bog lecture • Tues am - finish lake samples / limno summary • Tues pm - bog sampling • Tues pm - invert / zoop id / limno summary

  31. Class outline • Wed am - stream lecture • Wed pm - stream sampling • Wed pm - invert / fish id • Thurs am - Discussion of class projects • Thurs-Sat - data collection, analysis and ppt • Sun evening - group presentations • Written reports due (by email July 20)

  32. CLASS PROJECT 4 teams: Possible topics: • Oligotrophic vs eutrophic lakes • Oligotrophic lakes vs bogs • Zooplankton behavior w/ & w/out fish • Diurnal behavior in lakes vs streams

  33. Individual research projectsfish radio-telemetry (2 students) Habitat use by musky/pike Importance of streams

  34. General Methods • Radio/Acoustic Telemetry • Radio/Acoustic Transmitters • Remote Hydrophones

  35. Capture & Tagging

  36. Crayfish decomposition or tadpole ecosystem impacts
