1. Aquatic Ecology/Adv. Aquatic Ecology EEES 47/57/7730 – 3 credits (Fall 2011) Introduction Syllabus Why study aquatic ecology? Chapter 1 – Dodson

2. Aquatic Ecology: A discipline that uses the principles/methods of ecology to study aquatic environments.

3. Fig. 1.2 & 1.3. Location of lakes and streams mentioned in the text book

4. Presence of wetlands Northern Canada/ Alaska Continental U.S.Equatorial Neotropics Number of wetland scientists Latitude distribution of wetlands based on Matthews and Fung (1987), global lakes and wetlands database (GLWD), and gross wetland map (redrawn from Lehner and Doll 2004)

10. Why are you taking Aquatic Ecology A.I love lakes, rivers, and oceans and the organisms found in them B.Aquatic ecosystems provide a unique model system for the study of complex ecological processes C.I like to fish D.This was the only elective I could schedule

11. Describe your level of exposure to aquatic ecosystem. Have you done some research? Do you fish, snorkel, SCUBA, hike near rivers etc……..

12. epilittoral supralittoral eulittoral spray zone spray & waves between high & low water upper littoral; emergent veg middle littoral; floating veg lower littoral; submerged veg littoriprofundal; photosynthetic bacteria & algae profundal; no vegetation or algae littoral pelagia Within-Lake Zones epilimnion metalimnion thermocline hypolimnion

13. Introduction to some aquatic organisms & habitats  pelagic zone: water column in lake, ocean, or estuary (not often applied to rivers). plankton: pelagic organisms that can’t swim well in the horizontal plane ex. algae (phytoplankton), invertebrates (zooplankton), and larval fish necton: pelagic organisms that can swim well in the horizontal plane ex. adult fish  benthic zone: the bottom of a lake, river, estuary or ocean. Includes algae, plants, invertebrates, and fish.

14. plankton nekton benthos

15. River habitats  pool: deep, slow velocity, fine substrates  run: between pool & riffle  riffle: shallow, high velocity, gravel cobble substrate R R RR P P P P flow P R P R P gravel bars

16. Kalff 2002 Experimental duration vs. experimental area in limnology

17. Crater Lake, Oregon

18. Add image crater lake and Great Lakes watershed Crater Lake, Oregon: 600 m deep and 53 km 2 large caldera lake (NPS)

20. Fig. 1.12. Charles Elton's “box and arrow” nitrogen cycle model (1927)

21. Fig. 1.13. Generalized food web model of a lake (boxes labeled with names of aquatic taxa, as opposed to a trophic model dealing with energy and nutrient flow)

22. Fig. 1.14. Trophic model (Lindeman 1941)

23. Empirical predictive model

24. "A lecture is a process in which information passes from the notes of the professor into the notes of the student without passing through the minds of either." (Gilstrap and Martin, 1975)
