This practical manual of freshwater ecology and conservation provides a state-of-the-art review of the approaches and techniques used to measure, monitor, and conserve freshwater ecosystems. It offers a single, comprehensive, and accessible synthesis of the vast amount of literature for freshwater ecology and conservation that is currently dispersed in manuals, toolkits, journals, handbooks, 'grey' literature, and websites. Successful conservation outcomes are ultimately built on a sound ecological framework in which every species must be assessed and understood at the individual, community, catchment and landscape level of interaction. For example, freshwater ecologists need to understand hydrochemical storages and fluxes, the physical systems influencing freshwaters at the catchment and landscape scale, and the spatial and temporal processes that maintain species assemblages and their dynamics. A thorough understanding of all these varied processes, and the techniques for studying them, is essential for the effective conservation and management of freshwater ecosystems.

As a society, we use more than 100,000 different industrial compounds to promote health and treat disease, to grow food and to access clean water. While technological developments have improved our lives, most of these compounds end up in our oceans where they threaten marine life and human health. The practice of ocean waste disposal has had a long history and was initially believed to have minimal associated costs. However, it is now clear that although we can use the oceans for cheap waste treatment, we do this at the expense of the other key benefits we derive from the sea, notably human food supplies as well as its aesthetic value (including opportunities for recreation and tourism). Many of the pollution problems of previous decades appear to have been solved in the developed world, or at least managed to minimise their environmental impacts. However, despite treatment being available for some waste products, a potent mixture of toxic compounds and other potentially harmful additions continue to enter the marine environment every day. So, have the problems of marine pollution really been solved or have we simply generated a suite of different and potentially more complex challenges? In this volume we consider marine pollution from the perspective of the historical problems that are now successfully managed or solved, the ongoing problems and the emerging challenges that we face. These include hormone mimics, the residues from pharmaceuticals, nanometre-sized particles added to new materials, the millimetric plastics added to shampoos and cosmetics, the artificial fibres in the clothes we wear, and the noise and light pollution from our expanding industries and cities. Marine Pollution is aimed at senior undergraduates, masters and graduate level students studying marine sciences. It will also serve as a useful reference for researchers and professionals working in the fields of environmental management, marine planning, marine environmental regulation and protection, as well as those working for government departments, environmental NGOs and marine environmental consultancies.

This volume is a collection of short essays articles on the multidimensional aspects of the blue economy. It presents perspectives on the concept and the essential ingredients of the blue economy such as marine resources, maritime infrastructure and marine environment. International cooperative approaches to promote blue economy, the role of maritime governance and capacity building are discussed in the context of implementing the blue economy. The book also promotes the importance of sustainable utilization of the oceans which lies at the core of the blue economy.

This book is the third companion volume to 'An Introduction To Using GIS In Marine Biology'. It is designed to augment the information on using GIS in marine biology provided in that book, and, indeed, to be used alongside it rather than to be used independently as a stand-alone volume. Therefore, this book will be of most interest to those who have already read 'An Introduction To Using GIS In Marine Biology'.
This book consists of five exercises covering the practical use of GIS in marine biology using ERSI's ArcGIS(r) 10.2 GIS software and R statistical software. These exercises are based around integrating GIS and Species Distribution Modelling (SDM), and work through an example of an SDM from processing your survey data, through making raster data layers of environmental variables to constructing an SDM, visualising its predicted spatial distribution and validating its predictive ability. The exercises are designed to be followed in the order they are presented, and work with a specific data set, which can be downloaded separately for free.
Working through these five exercises will help the novice GIS user obtain experience in creating and using SDMs, and so develop their GIS skills. Unlike most other GIS tutorials, this information is specifically presented in a marine biological context and all the exercises use real data from a marine biological study. Therefore, these exercises are more likely to provide the kind of experience in using GIS that marine biologists will find useful and applicable to their own research.
These exercises are presented in the same easy-to-follow flow diagram-based format first introduced in the 'How To...' section of 'An Introduction To Using GIS In Marine Biology'. They are accompanied by images which show the user how their GIS project should look as they progress through the exercises, allowing them to compare their own work to the expected results.
This is part of the PSLS series of books which use Task-Oriented Learning (TOL) to teach the practical application of research skills to the life sciences. This involves demonstrating how these skills can be used in the specific circumstances in which they are likely to be required rather than concentrating on teaching theoretical frameworks or on teaching skills in a generic or abstract manner. By seeing how the similar processes are used to achieve a variety of different goals within a specific field, it becomes easier for the reader to identify the general rules behind the practical application of these processes and, therefore, to transfer them to novel situations they may encounter in the future.

"Stream Ecosystems in a Changing Environment" synthesizes current understanding in stream ecosystem ecology, emphasizing nutrient cycling and carbon dynamics, and provides a forward-looking perspective regarding the response of stream ecosystems to environmental change. Stream ecosystem ecology has undergone major advances in the past decade following a series of high-profile and innovative research initiatives focusing on nutrient cycling and metabolism. Each chapter includes a section focusing on anticipated and ongoing dynamics in stream ecosystems in a changing environment, and hypotheses regarding controls on stream ecosystem functioning. These innovative sections provide a bridge between papers published in peer-reviewed scientific journals, and researchers development of new ideas areas of study.
Provides a synthesis of the latest findings on stream ecosystems ecology in one volumeIncludes thought exercises and discussion activities throughout, providing valuable tools for learningOffers conceptual models and hypotheses to stimulate conversation and serve to advance research"

The general aim of this book is to explain the development of several types of models using an extremely small number of parameters in an attempt to find consistent properties of integral living matter within aquatic ecosystems. Starting from a minimal model of the whole study [ie: the ideal minimal ecosystem (IMES)], the authors developed a series of statistical models (size spectra, rank distribution, and regression models, including allometries). They then proceeded from ataxonomic to taxonomic size spectra to demonstrate and explain the high consistency of natural communities. Several types of species size-frequency distributions or "taxonomic size spectra" were applied, diminishing the importance of rare species and the assemblage time-space heterogeneity. A series of original studies written during the last thirty years to develop condensed, formalised models and empirical comparisons has demonstrated general patterns and the model's drawbacks; hence, several cycles of modernisation were fulfilled, revealing both the stability of natural aquatic communities and small-scale variability of the general pattern. Comparisons of several taxonomic hierarchy levels speak in favor of the whole-assemblage origin of the statistical mechanisms, supporting the long-term consistency of phytoplankton taxonomic size structure. Specific changes in the taxonomic size spectrum fine structure were evident and may be helpful for diagnostics, while the spectrum general pattern consistency can be helpful for monitoring and modeling the aim of this study. The consistency difference between several levels of the phytoplankton taxonomic hierarchy was demonstrated as a new phenomenon important for modeling, monitoring, and ecological forecast. Though stochastic dynamics of abundances and biomasses often emerge from experiments and mathematical models, some predictable patterns and indices emerged from large-scale studies of natural aquatic assemblages. Mathematical models demonstrated the formation of long-tail distributions produced by metabolic webs. Such consistency phenomena lead to explanatory ecological models based on concepts of the living whirl (G. Cuvier), living matter (V. Vernadsky), dissipative structures, and biogeochemical cycles. Aquatic (marine and freshwater) ecosystem management could be sufficiently strengthened, applying reliable patterns and descriptors suitable for forecasting and diagnostic purposes.
