As a result of the European Commission’s concern for the status of continental waters, and as a clear reflection of the notion of water as heritage to be conserved, in the year 2000 the Water Framework Directive (2000/60/CE) was enacted, its goal being to establish a framework to protect water and the different aquatic ecosystems by requiring the Member States to achieve a good ecological status in all their waters by 2015. Like all ecosystems, freshwater ecosystems undergo physical, chemical and energy-related changes, both of natural and anthropogenic origin. These disturbances affect the organisms living in them and those who utilize their resources. Therefore, evaluating these changes has become a very important task in order to better understand aquatic systems. The study and analysis of the ecological status of these ecosystems in relation to their conservation status and water quality is thus a fundamental tool for a more efficient and rational management of their resources, that is, a management that does not threaten the ecosystem. The present guide for the identification of Spanish freshwater macroinvertebrates aims to facilitate the job of those who go to great lengths to identify them in order to then determine biotic indices. It is not the aim of this book to serve as a zoological treaty, nor does it claim to add new information on the biology or the ecology of the taxa covered. This book is, simply, a working tool explicitly designed to facilitate the identification of the Spanish macroinvertebrates and the subsequent computing of biotic indices.

Holywell Coombe, an embayment in the chalk scarp overlooking Folkestone, Kent, was designated a geological Site of Special Scientific Interest in 1985 because it contains richly fossiliferous Late Quaternary sediments providing a unique archive of the last 13,000 years. The construction of the Channel Tunnel across the Holywell Coombe SSSI brought about a major rescue excavation, funded by Eurotunnel, that set an important precedent in Earth Science conservation. This multidisciplinary investigation has added enormously to our understanding of the environment and natural history of the Late-glacial and Holocene. The climatic complexity of the Late-glacial is recorded in the nature of the sediments, the fossils recovered from them and the soils developed within them. From the Neolithic, and especially during the Early Bronze Age, the slopes were destabilized as a result of forest clearance, leading to the accumulation of hillwash. Archaeological excavations in the hillwash have revealed evidence of prehistoric occupation and agricultural activity in the coombe. Eurotunnel also funded biological surveys of the local terrestrial and aquatic habitats. Combining these with the fossil evidence, it has been possible to document the pedigree of our present fauna and flora, providing one of the most detailed and comprehensive studies of its kind. With contributions from eminent Quaternary scientists from several countries, this work will be an important resource for researchers, lecturers and postgraduate students in Quaternary sciences - geology, geography, biology, ecology and archaeology - as well as for government bodies concerned with nature conservation and environmental protection.
