In the newest Hydrobiologia (Volume 676, Number 1 / November 2011) there is a bunch of articles about zooplankton. Wonderful! “Cladocera crustaceans: sentinels of environmental change” Eggermont & Martens write in the preface. I do believe they are. Jeppesen et al plead for including zooplankton to the European Water Framework Directive. No objections heard from me. What makes me especially happy is the high number of Finnishs names as authors.
