Biol 306 “Big questions”
A. Why do species differ in their population dynamics?
B. How do species coexist?
C. Are communities stable?
D. How much biomass is produced, and what is its fate?

Question A: Why do species differ in their population dynamics?
“Dynamics” result from multiple causes
Stochasticity at the population level: environmental vs demographic

Conceptual surveys…
“Ah-ha’s”
• Density dependence
• Population regulation
• Stochasticity
• Interpreting graphs & data tables
• Translating theory to actual examples
• Designing experiments to test hypotheses
