UNDERC education and research programs

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

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

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

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

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

11. Bergner Lake is “Oligotrophic”

12. Late Successional Eutrophic Pond

13. 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

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

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

20. Crampton Lake

21. Brown Lake

23. River Continuum Concept

26. Class projects - design data analysis

27. Location:

28. Peter Lake

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

30. “Big Bag” (Mesocosm) Experiment

31. Mesocosms in Peter Lake

33. 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

34. NEON is coming!!!

35. 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.

36. NEON Climate Domains

37. Drivers and Responses

38. The changing landscape
