Salish Sea Marine Survival Project researchers developed a qualitative network model to explore the impacts of environmental and oceanic drivers, changes in primary production and the food web, and anthropogenic pressures on salmon survival and health. They found that anthropogenic impacts most strongly affected salmon survival and abundance. Several food web components were also linked strongly to salmon. With this model, researchers can investigate the relative weight of multiple drivers impacting salmon. Read more: Sobocinski et al.
