Book Description
Biological Assessment and Criteria presents a state-of-the-art overview of the applications of biological assessments and biocriteria for water quality management in fresh waters. The book presents case studies which illustrate how bioassessment has been used to identify and diagnose water quality problems. It also provides examples of the use of qualitative and quantitative biocriteria as regulatory tools to complement water quality criteria and standards. The first book to present the technical foundation, rationale, program and policy relevance, and legal basis for the most accurate tools used to assess freshwater natural resource and regulatory efforts, this book provides useful and timely information for water quality managers.

Book Description
The overall aim of DEFINE is to provide a methodology to define reference conditions for nutrient concentrations in the coastal zone of the Baltic Sea. This will aid the national authorities that surround the Baltic basin in implementing the EU's Water Framework Directive (WFD) by providing decision-makers with a methodology to assess reference conditions and the degree of past and present departure from this state, such that appropriate policy and management measures can be taken at national and European levels. DEFINE adopts a palaeoecological approach grounded on diatom-based transfer functions, which can then be applied to define background total nitrogen (TN) concentrations in estuaries and coastal areas over the entire Baltic Sea. All transfer functions and necessary supporting documentation will be publicly available as a coherent management tool and accessible via the MOLTEN/DEFINE web page (http://craticula.ncl.ac.uk/Molten/jsp/).

Book Description
This new edition - now with Nancy Jackson as a co-author - continues the themes of the first edition: the need to restore the biodiversity, ecosystem health, and ecosystem services provided by coastal landforms and habitats, especially in the light of climate change. The second edition reports on progress made on practices identified in the first edition, presents additional case studies, and addresses new and emerging issues. It analyzes the tradeoffs involved in restoring beaches and dunes - especially on developed coasts - the most effective approaches to use, and how stakeholders can play an active role. The concept of restoration is broad, and includes physical, ecological, economic, social, and ethical principles and ideals. The book will be valuable for coastal scientists, engineers, planners, and managers, as well as shorefront residents. It will also serve as a useful supplementary reference textbook in courses dealing with issues of coastal management and ecology.

Book Description
The assessment of the ecological integrity of running waters is a prerequisite to an understanding of the effects of human alterations. The evaluation of degradation processes provides key information on how to avoid further negative impacts. The success of future conservation, mitigation and restoration activities will rely on sound assessment methodologies and their ecological relevance and applicability. Assessment methodologies are therefore an integral part of sustainable river management. This book synthesizes and discusses state-of-the-art experiences in assessment methodologies. Including the latest knowledge on structures, processes and functions of running waters as a fundamental basis for developing adequate assessment methods, the book focuses on method development, application, and in particular on integrated assessment methods. This book is directed at scientists and managers with the aim of more effective preservation, restoration and maintenance of the ecological integrity of running water ecosystems.
