Diatomeen im Süßwasser - Benthos von Mitteleuropa. Bestimmungsflora Kieselalgen für die ökologische Praxis. Über 700 der häufigsten Arten und ihre Ökologie. Von Gabriele Hofmann, Marcus Werum und Horst Lange-Bertalot.

The main aim of this book is to provide assistance for identification of taxa in applied hydrobiology, in particular water monitoring according to the implementation of EU Water Framework Directive. This book represents a somewhat reduced but condensed and updated freshwater diatom flora of Central Europe. Planctonic - halobious and most of the rare taxa are generally excluded. This special flora is restricted to diatoms that are frequent and/or abundant in the area of concern, to comply with the request of water monitoring in applied hydrobiology. This concerns most of the locally occurring diatoms relevant for biological analysis of inland waters for continuous quality control, and acts as a background for protection of aquatic habitats. 793 photographically documented taxa encompass more then 50 percent of the recent benthic freshwater diatom flora. Two general identification keys are given for the approximately 100 genera; additionally, 18 species - level keys for the most species - rich genera are given.
