Climate Change and Marine Food Webs: Navigating Structural Uncertainty Using Qualitative Network Analysis With Insights for Salmon Survival

open access: yesGlobal Change Biology, Volume 31, Issue 3, March 2025.
This study uses qualitative network models to explore how climate‐driven shifts in marine food web interactions could impact salmon populations. By testing 36 scenarios with varying species connections and responses to climate change, the analysis reveals that increased predation and competition consistently lead to negative outcomes for salmon.
