Agnes Karlsson

Agnes Karlsson is a Senior Lecturer at the Department of Ecology, Environment and Plant Sciences, Stockholm University. She holds a PhD in Marine Ecology (2010) and has conducted postdoctoral work at the University of Otago (2011-2013) and Stockholm University (2013). Her research focuses on marine ecotoxicology, food web ecology, and stable isotope analysis in the Baltic Sea, with a particular interest in how environmental changes affect ecosystem functioning and contaminant dynamics.

• Current roles include leading the national environmental monitoring program for vegetated seabeds since 2022.
• Supervises doctoral students Matias Ledesma and John Taylor.
• Collaborates with Baltic Sea Fellows, the Swedish Museum of Natural History, and international institutions.
• Teaches courses on Baltic Sea environment, ecotoxicology, and ecosystem management.

Her work integrates experimental studies, field observations, and long-term monitoring data to explore trophic interactions, climate change impacts, and pollution effects. She employs stable isotopes (δ¹⁵N, δ¹³C) to trace nutrient flows and assess food web responses to stressors like cyanobacterial blooms and contaminants. Recent projects address PAHs, PFAS remediation, and trophic position estimation accuracy.

Agnes Karlsson's publications span topics including invasive species dynamics, benthic-pelagic coupling, and isotopic niche variability. Her research emphasizes biodiversity-function relationships and mechanisms underpinning ecosystem resilience in species-poor systems. She contributes to environmental policy through data supporting Baltic Sea management and contamination mitigation strategies.
