Book Description
The present volume comprises aspects of both basic and applied limnology. They include works on physical, chemical, and biological limnology, as well as experimental approaches in selected areas. Contributions from investigators regarding aquatic conservation and biodiversity were specifically not available and therefore, these aspects are considered in various included works. Most manuscripts deal with lentic aquatic resources. This is not surprising since Mexican limnology followed the general study trend of that from temperate limnology. Despite this, we must emphasize that lotic resources in Mexico are quite important both locally and regionally. This does not mean that rivers are not under limnological research in Mexico, just that their study has only recently begun. It is the intention of the volume to stimulate a larger section of limnologists to further research in this field. It is to be hoped that policy-framing governmental authorities in Mexico will benefit from it, and consider some of the aspects described so that further damage to the epicontinental waterbodies can be halted, and remedial measures can be considered in the future.

Book Description
Bristle worms, or oligochaetes, are a large and diverse group of invertebrates. Most oligochaetes living in this region live in fresh or brackish water: no fewer than 136 species in total. They play an important ecological role thereby giving much information about the condition of the ecosystem. This important, bulky book is the first reference work on the freshwater and brackish water polychaetes in the Netherlands, Belgium and Germany. It offers a wealth of ecological and taxonomic background information. Includes a new user determination key. The key is based on characteristics that are relatively easy to distinguish, without specialized equipment. • a comprehensive overview on morphology, collecting and preservation, identification and ecology • 136 species including the oligochaete fauna of Germany • a new, practical key for the identification based on characteristics that are relatively easy to distinguish • many photographs and schematic drawings • backgroundinformation on ecology and distribution An unique tool for aquatic ecologists and water quality management.
