Below you can find 9 clips on the effects of chemicals at different levels of biological organisation, i.e. the individual level, the population level and the community/ecosystem/landscape level. The clips were made for an MSc course on chemical stress ecology and ecotoxicology. They are not made professionally nor comprehensive covering the whole field of science, just used as background material.
