Food webs with humans: In name only?
This chapter highlights the importance of considering people as integral to foodwebs. Despite extensive recent research on coupled human-natural systems, lacking are models that incorporate human behavior in a way that yields pragmatic insights into the management of multispecies fisheries. Using the US West Coast commercial fisheries system as a case study, this chapter develops a novel network approach of linking the social system (i.e., fishing communities) to the ecological system (the fish). The analysis reveals that fisheries that seem unconnected biologically, such as benthic Dungeness crabs and pelagic tuna, can in fact be strongly linked by fishing vessels that are active in both fisheries. Understanding how human behavior connects seemingly disparate ecological systems has important implications for fisheries managers seeking to balance human well-being with sustainable populations of fish.
