Harvey lab spends May in Norway

Elizabeth Harvey and her research team traveled to Bergen, Norway in early May for a month’s worth of experiments at the Norwegian National Mesocosm Centre at the Espegrend Marine Biological Station.

Skidaway scientists head to Norway for phytoplankton research

A team of UGA Skidaway Institute scientists, led by Elizabeth Harvey, will be spending the next few weeks at a sophisticated mesocosm facility near Bergen, Norway. The team will be at will be at the station to study the interaction of the globally important phytoplankton Emiliania huxleyi (E. hux) with the viruses that infect and kill E. hux cells. You can follow along with the team and their international collaborators through their blog.


Skidaway Institute scientists published together in PLOS ONE journal

Skidaway Institute scientists Jens Nejstgaard, Stella Berger and Zachary Tait were part of a team of 30 scientists from more than ten countries collaborating on a paper published recently in the scientific journal PLOS ONE.

The scientists studied the effects of future climate change scenarios on plankton communities of a Norwegian fjord using a mesocosm approach. Natural plankton were enclosed and treated with inorganic nutrients (eutrophication), lowering of pH (acidification) and rising of temperature (warming). Acidification and warming had contrasting effects on the phenology and bloom-dynamics of autotrophic and heterotrophic microplankton. The development of mass balance and proportion of heterotrophic/autotrophic biomass predict a shift towards a more autotrophic community and less-efficient food web transfer when temperature, nutrients and acidification are combined in a future climate-change scenario.

According to Nejstgaard, “We suggest that this result may be related to a lower food quality for microzooplankton under acidification and warming scenarios and to an increase of catabolic processes compared to anabolic ones at higher temperatures.”
