Abstract
Opinion This is a series of contributions, expressing explicit opinions with regard to contemporary topics in limnology. These texts will mostly be based on new books with a large impact, but can also refer to other currently debated topics. Suggested topics for opinion articles or documented reactions to published contributions should be sent to the editor-in-chief; they will be considered for publication in subsequent issues.
