As of January 1, 2007, beginning with Volume 168, Archiv für Hydrobiologie has been renamed to "Fundamental and Applied Limnology (new ISSN: 1863-9135)", retaining the former title as subtitle. At the same time, cover design was modernized and the page format is now the common sub A4 (27.4x21cm, 8"x11.7") format, showing a superior layout. The agenda has remained the same: the publication of high impact, peer reviewed research papers in freshwater science.
