Interactions within Ecosystems
How are living systems interconnected and interacting?
show
  • Compare biodiversity among microhabitats (e.g., phylosphere v. rhizosphere, human microbiome, coral reefs)
  • Predict the abiotic and biotic characteristics of new habitat over the short and long term (e.g., glacial stream, post-fire, old field).
  • Choose and use multiple representations (e.g., explanation, graphs, equations, diagrams) to explain how systems are interacting (e.g., Lyme disease system, Isle Royale system, Rabbits in Australia).
  • Choose and use multiple representations (e.g., explanation, graphs, equations, diagrams) to explain how organisms are constrained in the number and types of interactions in which they can engage by their evolutionary history (genetic factors) and circumstance (location, temporal variability in environment).
How do systems change over time?
show
  • Construct a model to explain how the interactions among the biotic and abiotic factors of a system can vary (direction, magnitude, frequency) in space and time.
  • Predict and explain the response of disturbance by: -individuals (e.g., acclimation, death, migration) -populations (e.g., adaptation, migration, extinction) -communities and ecosystems (e.g., resiliency, functional redundancy, large changes to ecosystem structure)
