Impacts of Climatic Change and Fishing on Pacific Salmon Abundance over the past 300 Years
The effects of climate variability on Pacific salmon abundance are uncertain because historical records are short and are complicated by commercial harvesting and habitat alteration. We use lake sediment records of δ15N and biological indicators to reconstruct sockeye salmon abundance in the Bristol...
