2012 RESULTS - rev. 2/2/12
Readings LC Chapter 5 Lesson points
- What key abiotic factors control biotic processes in lakes? What is the state of these in winter - see next questions.
- What is the typical seasonal cycle in the vertical structure of these factors for seasonally-cold, mid- and high latitude lakes?
- What are the mechanics behind these seasonal changes? --
- For example, how does the density of liquid water vary with temperature? And how does this play a role in the changing vertical structure of lakes from Fall to Winter to Spring?
- Are winter frozen-over lakes in the Colorado Rockies biologically active?
- If so, what processes are occurring under the ice? And with what vertical structure?
- What is the general composition of wintertime biotic communities in such a lake and its sediments?
- Is there evidence of biotic seasonal succession in wintertime observations?
