Here is a simplified, hypothetical "map" of the system, so you can see how things could be connected.
This map (thumbnailed on right) is a conceptual system, a model offering one of many possible explanations for what seems to be happening. It provides a graphical way of viewing, and critiquing, a hypothetical feedback system. Using this map, I've built a simulation of these structures to see how such a simplified system might act over time, given the assumptions in the model. It is not meant as a map of the Bering Sea eco-system, but more as a systematic, structured basis for infromed conversation and further study. Graphs showing the output of the simulation run are just below. The part of the model which includes the variables for "fish" and "fishing industry" is derived from the "Fishbanks" model, developed by Dr. Dennis Meadows.
