Disruptions to ecosystems impact the dynamic homeostasis or balance of the ecosystem.
To foster student understanding of this concept, instructors can choose an illustrative example such as:
• Invasive and/or eruptive species
• Human impact
• Hurricanes, floods, earthquakes, volcanoes, fires
• Water limitation
• Salination
Mathematical models and graphical representations are used to illustrate population growth patterns and interactions.
Evidence of student learning is a demonstrated understanding of each of the following:
1. Reproduction without constraints results in the exponential growth of a population.
2. A population can produce a density of individuals that exceeds the system’s resource availability.
3. As limits to growth due to density-dependent and density independent factors are imposed, a logistic growth model generally ensues.
4. Demographics data with respect to age distributions and fecundity can be used to study human populations.

Snow Lake FT- tentatively set for Tuesday- planned absence forms signed and returned by tomorrow- check AP Bio Weebly site (home page) for pre field trip info!!!.
Finish Snow Lake case study-
Great podcast (KUOW- special report on climate change)
http://earthfix.kuow.org/water/article/toxic-algal-blooms-and-warming-waters-the-climate-/
AAAS article- Human population growth and sustainability
Directions read the assigned graph or figure, describe the major trends. What conclusions might be drawn from these graphs? What questions do you have for the author of this study? Be ready to present to the class.
Ecological connections project- mini lecture
