Genre: Science

This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.

Chelicerata are a basically terrestrial group of invertebrates, including many clades whose representatives have never found an evolutionary way to aquatic live. An exception is made by the spiders, which include a considerable number of hygrophilous species, and by the highly diverse aquatic mites which in inland water habitats are represented by members of numerous different clades having evolved an aquatic or amphibious lifestyle. For the first time the present taxonomic knowledge about these different groups of invertebrates is brought together in an overview for the Central-European fauna. This volume includes taxonomic keys and ecological information concerning hygrophilous and aquatic spiders, a general introduction to mites, and the treatment of three mite groups generally known from terrestrial habitats. Also, the freshwater-dwelling representatives of the originally marine Halacaridae are treated, and the species-rich true freshwater mites (Hydrachnidia) are represented in a general overview.
