Congratulations to PhD student Emma Johansson for the publication of her first paper for her thesis! In this study Emma has explored the microcystin variants (chemotypes) of 130 Microcystis botrys strains from a single bloom season. See https://www.mdpi.com/2072-6651/11/12/698.
Former lab member Ingrid Sassenhagen just published our paper on the Gonyostomum semen chloroplast genome in a special volume in Genes. This work was done using whole-genome amplification from a few isolated chloroplasts, thereby circumventing having to culture cells. Please … Continue reading
Project description Microscopic organisms are widespread and many species have a cosmopolitan distribution. This pattern suggests that microorganisms (such as phytoplankton), in contrast to most larger organisms, have unlimited dispersal. Unlimited dispersal implies high migration rates and gene flow within … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
