On Friday the 1st of December Patrick Rozema will defend his thesis 'To diversity and beyond: Shifting Antarctic microbial communities along environmental gradients'.
The Antarctic Peninsula, marine (micro)biology along it, is changing rapidly. This thesis, to be defended on international Antarctica Day, presents insights into the relation between phytoplankton (microscopic plants), bacteria and the environment. Research conducted at the British Antarctic research station Rothera, where the Dutch have opened a lab in 2012, shows that decreasing sea ice cover during winter results in low concentrations of phytoplankton in the following summer and that the summer phytoplankton strongly represents that of the winter. This means a lack of diatoms, pivotal in the classical Antarctic food web and crucial for long term storage of CO2. A future scenario with less sea ice and more wind mixing will result in increased proportions of flagellated species....read more.
