Tiivistelmä
Global environmental change is getting more intense, and marine life is also under a turnaround that could possibly alter human society in a large scale as well. This study is done to get new information about habitat stressors for newly intruding exotic bloom forming cyanobacterium species Cylindrospermopsis raciborskii that is expected to spread to the Nordic. This algae is found to be highly toxic and difficult for the original algae species to rival with once it has been establishing its new areas.
This study was done cultivating four strands of C. raciborskii, captivated from different places at different times during past few decades, on a temperature gradient and results implicated that there are regional variations in cold tolerance for this species and specially newest and northernmost strain. Further research on molecular level on its adaptative strategies is needed to fully understand the efficiency and possibly estimating the time line of it's spreading for the best results for preparedness.
