Aquatic ecology

Ann Kristin Schartau

Major practical experiences cover project management concerning research and monitoring in freshwater (rivers and lakes) and in marine environments (estuarine and coastal waters). Specialization on freshwater biodiversity and water quality. Project leader for several national projects on implementation of the EC Water Framework Directive in Norway: Design of a National Monitoring Network for Reference Sites, Design of a National Network for Surveillance monitoring in freshwaters, Evaluation of methods for monitoring and assessment of freshwaters c.f. the WFD. Experience from international work on standardization of biological methods, and different aspects related to the implementation of the ECC’s Water Framework Directive.

Jon Hamner Magerøy

I have extensive experience with research on and monitoring of freshwater mussels in Norway, Canada and the USA. Research topics include habitat requirements, genetics, human impacts and ecosystem services, among others. As a part of this work, I have also studied confirmed and potential host fish for mussels. Therefore, I have gained experience with a variety of freshwater fish, both through experiments and field work. During my Ph.D., I worked on evolutionary theories on parasites that castrate their hosts. Specifically, I worked on a bacterium that castrates water fleas (daphnia).

Through my work on freshwater mussels I have also become a member of the IUCN mollusc specialist group (Molluscs), member of the management committee for the research network CONFREMUS (confremus.eu), which is a COST network for freshwater mussels in Europe, and member of the Freshwater Mollusk Conservation Society (FMCS).

Hoveddelen av aktiviteten er relatert til økologi og livshistorie hos resident og anandrom laksefisk, og knyttet nært opp mot forvaltning. God felterfaring, spesielt i arktiske strøk (Svalbard, Nord-Norge og Nord-Vest Russland). Forskningsaktiviteten involverer en kombinasjon av feltinnsamling, bearbeiding i laboratorium og teoretiske/statistiske analyser.
