Climate-induced changes in carbon flows across the plant-consumer interface in a small subarctic lake
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 Daphnia (clad...

Reconstructions of past food web dynamics are necessary for better understanding long-term impacts of climate change on subarctic lakes.
