Research Highlights Changes in Marine Food Systems

Recent research indicates that global ecosystems are experiencing notable changes, particularly in marine food systems that rely on both terrestrial and aquatic ecosystems. Lauriane Ribas-Deulofeu from Nord University is investigating how warming oceans affect two key groups of plankton: phytoplankton and zooplankton, which are essential for the marine food web.

Ribas-Deulofeu's study focuses on the species composition and abundance of these plankton, suggesting that fish may face reduced food availability and lower quality nutrition. The research employs AI technology to analyze plankton samples more efficiently, allowing for quicker data collection and analysis, which is crucial for environmental management.

Phytoplankton, which produce organic matter through photosynthesis, and zooplankton, which feed on them, are vital for sustaining marine life. Changes in phytoplankton populations could have widespread effects on the entire food web, including fish stocks. The study also emphasizes the importance of monitoring plankton to understand their role in climate regulation, as they absorb carbon dioxide and produce oxygen.

Collaborative efforts across Europe are underway to address these challenges, with the BioBoost+ project linking eight institutions in seven countries to standardize AI use in microplankton analysis.
