Adaptation of Daphnia magna to Microcystis aeruginosa

During eutrophication of lakes, often cyanobacterial blooms emerge due to phosphorus input. Many cyanobacteria contain toxic compounds regarded as a defence against grazers. Besides the well known microcystins another similarly important group of cyanobacterial secondary metabolites are inhibitors of digestive proteases in Daphnia. I investigate the evolution and adaptation of Daphnia to the presence of cyanobacterial protease inhibitors.
