Rotifera VII : Proceedings of the Seventh Rofifer Symposium, held in Mikołajki, Poland, 6-11 June 1994

The Proceedings of the Seventh International Rotifer Symposium, __Rotifera VII__, spans subjects from community ecology through biochemistry, from the most basic science through the most clearly applied technology. Some papers report exceptional progress in our knowledge of rotifer anatomy and biochemistry, as well as rotifer molecular biology, evolution and life histories. The book also contains an interesting article describing a hundred years of Polish contributions to rotiferology as well as papers discussing both general patterns of rotifer biogeography and rotifer distribution in different habitats, together with many aspects of the ecology of rotifer species, populations and communities. __Audience:__ This update on rotifer taxonomy, biology and ecology will be of great interest to zoologists, especially hydrobiologists studying the structure and function of freshwater zooplankton.
