In a paper 1935, Drouet and Cohen, described that they had found the rarely observed flagellate Gonyostoum semen in a sphagnum swamp in Woods Hole, Massachusetts, USA. This locality is referred to by residents as the Cedar Swamp. This year we managed to enter the swamp, find the open water, and resample. Just as in 1934, there was a major bloom of Gonyostomum, dominated the phytoplankton community entirely! The next step is comparative analyses to European populations.
This summer we will have two major field sampling campaigns going on. One is here in southern Sweden, in lakes Ringsjön and Vombsjön. The project is focused on the seasonal dynamics of toxin and non-toxin producing strains of the cyanobacterium Microcystis botrys, and is part of Emma Johansson’s PhD project. The second field sampling expedition will be across the U.S. This sampling is part of Raphael Gollnisch’s PhD project, and is focused on collecting samples of the invasive nuisance raphidophyte Gonyostomum semen. Fingers crossed that both sampling campaigns will be successful!
Together with Dr. Anna Godhe (PI), my colleagues Drs. Olof Berglund, Helena Filipsson, and I, were funded to work on phytoplankton resilience and evolution in response to pollution. The project, entitled Live to tell: Have phytoplankton evolved in response to environmental pollution during the last centuries? is funded by the Research Council Formas.
I would like to welcome Raphael Gollnisch, a new PhD student to our group. Raphael will be working with the invasive freshwater species Gonyostomum semen, investigating the underlying differences between expanding and non-expanding lineages. He will utilize single-cell genome amplification approach in combination with population genomic analyses. Raphael is part of the Marie Curie ITN SINGEK.
I would like to welcome our new member Emma Johansson to my lab. Emma will be working on her PhD on population genomics of the toxic cyanobacterium Microcystis botrys. The focus of her PhD project is to try and understand the dynamics and spatial structure of micocystin and non-microcystin producing subpopulations.
A postdoctoral fellowship position is available to work on a project examining the major evolutionary transition to multicellularity in green algae. This project is led by Dr. Charlie Cornwallis in collaboration with Profs. Karin Rengefors and Lars-Anders Hansson. The project will use a combination of experimental evolution on target groups (green algae), and comparative analyses of the independent transitions to multicellularity across the tree of life using genomic, ecological and life-history data. This position will provide the opportunity to explore social evolutionary theory and develop skills in experimental design, bioinformatics, phylogenetic comparative methods and meta-analysis. Closing date for applications is July 15, 2016. For more information and application go to: https://lu.mynetworkglobal.com/en/what:job/jobID:103762/where:4/
A second PhD position is in the process of being filled. Note that the closing date has passed. This is a position focused on single-cell population genomics within eukaryotic phytoplankton. The position is one of 15 within a European network initiative, SINGEK. See the link below for a description, eligibility (note special ones for EU mobility), criteria, and more https://lu.mynetworkglobal.com/en/what:job/jobID:92366/where:4/ and http://www.singek.eu/call-for-positions/
