The Department of Organismal Biology hereby invites all interested to a docentship lecture in the subject Environmental Toxicology.

Abstract:

Linear economies (make, use, dispose) dominate our consumption and have caused Earths’ climate to change and chemicals of human origin to be distributed across ecosystems. Freshwater and marine habitats are particularly vulnerable to the resulting perturbations as, here, up to 50% of primary production comes from unicellular phototrophs (‘phytoplankton’) which, unlike migratory animals, cannot journey away from stressors. Despite their fundamental role in aquatic ecosystem health, we lack insight into the mechanisms by which different stressors disturb phytoplankton cells and their populations. This is in part because many stressors interact and cause departures from data gathered in ‘traditional’ laboratory experiments, which typically apply single stressors only. In this lecture, I will introduce selected stressors relevant to the life of phytoplankton, describe their variability and interaction and discuss this in the context of technological advances that now enable more realistic experiments with phytoplankton cells.

The lecture is an obligatory teaching test for those applying for admittance as docent and it should be possible for students and others with basic academic education in the relevant field to follow it. The lecture will last for 40-45 minutes and afterwards the audience may ask questions. The lecture will be given in English.
