Code and data for: Modeling the interaction between salmon management and consumption by coastal brown bears ...
Harvest management policy for species with strong trophic connections can reverberate through food webs and cause unintended consequences such as altering the abundance of a harvested species' predators or prey. Pacific salmon ( Oncorhynchus spp.), a key food for many predators and an economica...
