Aquatic entomology has undergone major advances in recent times. For example, aquatic insects are now routinely used to test hypotheses in contemporary ecological theory and to model predictive changes resulting from climate change. Research has also revealed the importance of aquatic insects in the spread of diseases, in the biological assessment of water quality, and in the reconstruction of past environments on earth. Further, it is now accepted that the larvae of aquatic insects play a pivotal role in the breakdown of terrestrial leaf litter and provide an important food source for fishes, both in nature and aquaculture.This book presents these findings together with the background information necessary to understand them, and provides references to classic and more detailed studies in the literature. Only a limited prior knowledge of general ecology or entomology is assumed on the part of the reader. The book will therefore appeal to advanced undergraduate students taking courses in aquatic biology or entomology, as well as to research workers in ecology and pure and applied entomology seeking an overview of this fascinating field of study.

The Handbook of Holocene Palaeoecology and Palaeohydrology was originally published in 1986 and has been out of print for many years. The present book is a reprint of that volume, reprinted without changes to either text or illustrations.The Handbook of Holocene Palaeoecology and Palaeohydrology was a breakthrough in standardizing methods applied in palaeoecology and palaeohydrology. Particular attention was paid to Holocene environmental changes in the temperate zone, but most methods can be applied to older Quaternary deposits and to areas outside the temperate zone. The need for uniform methods of correlating stratigraphical data on a continental scale was emphasized.There have, of course, been methodological developments and a research expansion during the last 15 years, particularly in palaeolimnological studies. However, the basic methods for palaeoecological research strategy, for sampling and documentation of mire and lake deposits, for dating and for palaeochemical and palaeobiological analyses, are still the same as when the book was published.The book will be a valuable reference work for those involved in the field of Quaternary paleoecology, including ecologists, geologists, geographers and archaeologists.
