The dataset consists of lake 12 Finnish lakes food web (phytoplankton, zooplankton, and fish) across a nutrient gradient (total phosphorus and total nitrogen). Data corresponds to biomass and community composition, phytoplankton size and classification based on edibility for zooplankton. Phytoplankton primary production (volumetric production and productivity) calculated as incorporation of 13C into fatty acids and their relationship with total phosphorus. In addition, fatty acid content of EPA and DHA of zooplankton and fish in different species is analysed and its relation to production and total phosphorus is analysed. Scripts of data and data processing together with input and output files are given. For more detailed description, see the attached documentation.
