Trophic interactions

Theme 2

Questions addressed within theme 2:

  • Are the indirect effects of climate change via organic carbon and nutrients affecting fish predation? Where has it gone the opposite: What is the effect of increased planktivores on the biodiversity of the planktonic food web?
  • How is regulation of fish communities and cascading effects on the food web affected by harvesting and climate-induced changes in productivity?
  • Do long-term monitoring data at lower trophic levels correlate with long-term data on fish, particularly for the Bothnian Sea? What are the recruitment habitats of perch and pike? And can they be defined through isotope analyses? How can the results be used for ecosystem-based fisheries management?
