Sedimentary legacy of sockeye salmon (Oncorhynchus nerka) and climate change in an ultra-oligotrophic, glacially-turbid British Columbia nursery lake
… of spawner density (ä15N) and algal production (fossil pigments and diatoms) to show that lake trophic status is often regulated by climate and harvest via MDN from adult spawners. However, the strength of these controls and the utility of the paleolimnological techniques for measuring them are …
