Discussion of Redfield (1958) and Klausmeier (2004)

  • Define stoichiometry
  • Understand how we can use stoichiometry to address ecological questions
  • Identify research frontiers in stoichiometry
  • Identify assumptions of models
  • Understand how to utilize an equilibrium analysis
  • Optimal strategies and tradeoffs

In your own words, what were the key underlying assumptions of the Klausmeier model?  Were the assumptions justified?

Discussion of homework

Group activity: patterns in data

  • Link across scales of organization
  • Utilize and understand lots of data
  • Recognize patterns leading to a hypothesis

Write up the question and hypothesis developed in class. What pattern(s) led you here? Why did you develop this hypothesis?

Read Sterner (1990)

Discussion of Sterner (1990)

Introduction to modeling project 

  • Formalizing ideas (operationalizing)
  • Critically read and analyze theoretical papers

Develop a box and arrow diagram of a model you want to explore.  Begin translating these into a system of equations.
