Systems Ecology - An approach for integrating
Poster location: CNR, 2nd floor, NE side of elevator |
|
Build a systems model that represents all of the
interactions and flows in the ecological system shown on the poster. Use a systems model to integrate and scale ecological processes from the molecular to ecosystem levels. Understand the structure and function of ecological systems so that: (1) ecosystems can be properly managed, (2) the response of ecosystems to future disturbances can be predicted, and (3) damaged ecosystems can be restored to be fully functional and stable. |

Challenge | |
Build a systems model that
illustrates all components and interactions that determine the
incident radiation on a leaf. Start with the uppermost leaf of the
young balsamroot plant shown in the photograph. Then, added more
complexity in the model by accounting for variations in leaf form,
leaf surface characteristics, location (e.g., slope, aspect,
latitude, etc.), and environmental factors that influence incident
radiation. Note that systems models may seem initially easy and simple to develop, accounting for each step (source, sink, state and driving variables, feedbacks, etc.) and the interactions can lead to a very detailed and complex systems model. That's life.
