Matthias Stöck

Matthias Stöck is a researcher at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) in Berlin, Germany. He leads research on genetic and evolutionary processes in fish and other vertebrates, focusing on sex determination mechanisms, hybrid speciation, and environmental impacts on aquatic organisms. His work bridges molecular genetics and ecosystem-level dynamics.

Research Themes:

• Evolution of sex chromosomes across vertebrates
• Environmental endocrine disruption effects
• Comparative genomics of fish and amphibians
• Biodiversity conservation in freshwater systems

Key Article Trends: His recent publications analyze genomic responses to environmental stressors (e.g., synthetic androgens and estrogens), evolutionary patterns in hybrid and polyploid species, and conservation strategies for standing water ecosystems. Methodological contributions include the RADSex pipeline for sex determination studies.

Projects: He leads the ODER~SO investigation into the 2022 Oder River environmental disaster and coordinates research on "Breaking the rules: modifications of sexual reproductive pathways in vertebrates" (2023-2026).
