Between 3 and 8 July, Peter von Dassow, associate research at the Millennium Institute of Oceanography (IMO), visit Roscoff, France.
Here, von Dassow will be working with Myriam Valero, in data analysis of genetics population of the coccolithophore Emiliania huxleyi in the South-Eastern Pacific Ocean.
In order to compare the rate of genetic differentiation at levels of mitochondrial and nuclear markers between populations, the research considers coastal and ocean areas, from St. 18 in Concepción coast, Coquimbo’s coast, the zone close to Robinson Crusoe Island and the open ocean off Peru.
The researcher emphasizes the importance of the study of this species: "this species of phytoplankton is cosmopolitan and has colonized different epipelagic environments from highly productive regions of upwelling near the coast to the oligotrophic ocean, and from sub-polar waters to equatorial and tropical waters. Thus it presents a model species for understanding processes of adaptation to different environments in the ocean".
The trip is funded by Unité Mixte International 3614 CNRS UPMC Sorbonne Université “Evolutionary Biology and Ecology of Algae” and the International Research Network "Diversity, Evolution and Biotechnology of Marine Algae” (CNRS GDRI N° 0803).
