Andreas Bryhn


Jag är forskare, projektledare och studierektor vid SLU Aqua. Min verksamhet handlar främst om kustvattenmiljö - exempelvis ekosystembaserad förvaltning, ekosystemtjänster, ekosystemräkenskaper, utvärdering av provfiske, beståndsskattning av ål, modellering och grön infrastruktur. Jag är även Academic Editor för vetenskapstidskriften PLoS One.
