The aim of this book is to discuss practically useful (operational) bioindicators for sustainable coastal management, criteria for coastal area sensitivity to eutrophication and an approach set a "biological value" of coastal areas. These bioindicators should meet defined criteria for practical usefulness, e.g., they should be simple to understand and apply to managers and scientists with different educational backgrounds. Central aspects for this book concern effect-load-sensitivity analyses. One and the same nutrient loading may cause different effects in coastal areas of different...

While toxicity testing procedures and hazard assessment approaches have been published in past decades, many are wanting in detail for users to fully understand or reproduce successfully. Small-scale freshwater toxicity investigations (Volumes 1 and 2) responds to this need by providing comprehensive information on biological testing which is normally scattered and difficult to find.

In Volume 1, 15 chapters on toxicity tests are described in great detail by way of a homogeneous structure that all contributors had to follow. These...

The peculiarities of water as an environment for microbial growth, the taxonomy of aquatic microorganisms, and their influence on such areas as global climate and pollution are examined in this book.

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...

For many years the reduction of eutrophication in the Baltic Sea has been a hot issue for mass-media, science, political parties and environmental action groups with manifold implications related to fisheries (will the Baltic cod survive?), sustainable coastal development (have billions of Euros been wasted on nitrogen reductions?), ecotoxicology (can we safely eat Baltic fish?). This book takes a holistic process-based ecosystem perspective on the eutrophication in the Baltic Sea, with a focus on the factors regulating how the system would respond to changes in nutrient loading. This...

This volume presents the four sub-themes of the 38th European Marine Biology Symposium. These are patterns and processes, assessment, threats and management and conservation. Understanding the functioning of marine ecosystems is the first step towards measuring and predicting the influence of Man, and to finding solutions for the enormous array of problems we face today. The papers in this book represent current research and concerns about Marine Biodiversity in Europe.

Now a major motion picture starring Drew Barrymore, Ted Danson, Kristen Bell, Tim Blake Nelson, John Krasinski, and Vinessa Shaw--an account of the dramatic rescue of three gray whales trapped under the ice in Alaska in 1988.
Set in Cold War-era 1988, Big Miracle tells the real story behind the remarkable, bizarre, and oftentimes uproarious event that mesmerized the world for weeks. On October 7, an Inuit hunter near Barrow, Alaska, found three California Gray whales imprisoned in the Arctic ice. In the past, as was nature's way, trapped whales always died. Not this time. Tom...

Dr. Denise Herzing began her research with a pod of spotted dolphins in the 1980s. Now, almost three decades later, she has forged strong ties with many of these individuals, has witnessed and recorded them feeding, playing, fighting, mating, giving birth and communicating. Dolphin Diaries is an account of Herzing's research and her surprising findings on wild dolphin behavior, interaction, and communication. Readers will be drawn into the highs and lows--the births and deaths, the discovery of unique and personalized behaviors, the threats dolphins face from environmental changes,...
