food web for Bering Sea fish and other species, graphic showing connections between species This is a path diagram for the Bering Sea and Aleutians Islands marine ecosystem. It shows linkages between ecosystem variables. Arrows correspond to suspected relationships. An arrow pointing from X to Y indicates that a change in X is estimated to cause a change in Y. The number next to each arrow shows the estimated magnitude of the change (red arrows indicate a negative change and blue arrows indicate a positive change).
