Lecture 12 - November 10, 2009

Essential Background

Outline

  • reinforcing feedback (review)
  • biomes
  • ecoregions

Vocabulary (see this page)

Using viewers and Multiple Perspectives

  • network and systems feedbacks that stabilize certain states
  • scale of study (population, community, ecosystem, biomes or ecoregions)

Life lessons that our grandmas taught us:

You need to know where you live.

Mini-quiz - you need to know:

 

 
 

Interactions between climate, plants and soil

lead to broad regions (biomes)

might need smaller, more refined definition for study (ecoregions)

scale

  • distance and time
  • ecological studies are focused at particular scales
    • individual
    • population
    • community
    • ecosystem
  • techniques and approaches
  • cross-scale studies are an intellectual challenge
