New project on phytoplankton resilience and evolution

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.

Another new PhD student

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.

Welcome to new PhD student

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.

Postdoctoral fellowship

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:

PhD position within EU ITN-network

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 and

Population genetic structure in a large marine diatom bloom

We found that the Baltic Sea spring diatom bloom displayed strong spatial structure driven by oceanographic connectivity and geographical distance, which was enhanced by the pronounced salinity gradient This work was done within the Prodiversa Nordforsk network and would not have been possible for a single group to do alone. More of this Nordforsk, please!

Congratulations Dr. Sefbom!

On Friday September 25th, Josefin Sefbom, PhD student on the joint project “Dispersal barriers of microalgae” defended her PhD thesis. Congratulations! Josefin still has some copies of her thesis so do contact her if you are interested.

New paper by Ingrid Sassenhagen

Ingrid Sassenhagen just published the last paper of her thesis in Journal of Plankt0n Research. In this papers she has investigated if cysts of the raphidophyte Gonyostomum semen germinates and starts growing best in their own lake water, and thereby outcompete any newcomers. Read her story here.

Presentation at the Marine Biological Laboratory, Woods Hole

On July 9th I gave a short presentation in the MBL awardee brown bag seminar series on “Exploration of invasion patterns of a harmful algal bloom species using RAD-tag sequencing and population genomics”. I am spending seven weeks this summer working at the MBL on a Whitman summer investigator research grant.

Sampling in Maine

Successful sampling in  Maine. With the help of Dr. Ramunas Stepanauskas at Bigelow Laboratory, I found Gonyostomum in a humic lake in Nobleboro, Maine. For the next weeks I will be busy isolating and  attempting to culture cells sampling_mainefrom this population.sampling_lake
