Climate-induced changes in carbon flows across the plant-consumer interface in a small subarctic lake
Abstract Reconstructions of past food web dynamics are necessary for better understanding long-term impacts of climate change on subarctic lakes. We studied elemental and stable isotopic composition of sedimentary organic matter, photosynthetic pigments and carbon stable isotopic composition of Daph...
