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...

The deep sea covers over 60% of the surface of the earth, yet less than 1% has been scientifically investigated. There is growing pressure on deep-sea resources and on researchers to deliver information on biodiversity and the effects of human impacts on deep-sea ecosystems. Although scientific knowledge has increased rapidly in recent decades, there exist large gaps in global sampling coverage of the deep sea, and major efforts continue to be directed into offshore research.

Biological Sampling in the Deep Sea represents the first comprehensive compilation of deep-sea...

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,...

The world's nearly 7,000 species of crabs are immediately recognizable by their claws, sideways movement, stalked eyes, and thick outer shells. These common crustaceans are found internationally, thriving in various habitats from the edge of the sea to the depths of the ocean, in fresh water or on land. Despite having the same basic body type as decapod crustaceans true crabs have heavy exoskeletons and ten limbs with front pincer claws crabs come in an enormous variety of shapes and sizes, from the near microscopic to the giant Japanese spider crab.

In Walking Sideways,...

The heartbreaking and true story of a lonely orca named Luna who befriended humans in Nootka Sound, off the coast of Vancouver Island by Michael Parfit and Suzanne Chisholm.

One summer in Nootka Sound on the west coast of Vancouver Island, British Columbia, a young killer whale called Luna got separated from his pod. Like humans, orcas are highly social and depend on their families, but Luna found himself desperately alone. So he tried to make contact with people. He begged for attention at boats and docks. He looked soulfully into people's eyes. He wanted to have his tongue rubbed....
