Book Description
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Book Description
During the last decades there has been an increasing evidence of drastic changes in marine ecosystems due to human-induced impacts, especially on benthic ecosystems. The so called “animal forests” are currently showing a dramatic loss of biomass and biodiversity all over the world. These communities are dominated by sessile suspension feeder organisms (such as sponges, corals, gorgonians, bivalves, etc.) that generate three-dimensional structures, similar to the trees in the terrestrial forest. The animal forest provide several ecosystem services such as food, protection and nursery to the associated fauna, playing an important role in the local hydrodynamic and biogeochemical cycles near the sea floor and acting also as carbon sinks. The present book focus its attention on these three dimensional animal structures including, for the first time, all the different types of animal forests of the world in a single volume.

Book Description
Ocean Acidification and Marine Wildlife: Physiological and Behavioral Impacts provides comprehensive knowledge on how decreases in the pH of the world's oceans is affecting marine organisms. The book synthesizes recent findings about the impacts of ocean acidification (OA) on marine animals, covering the physiological and behavioral effects upon marine invertebrates and vertebrates, the potential physiological and molecular mechanism affects, and interactions of OA with other environmental factors. Written by international experts in this research field, this book summarizes new discoveries of OA effects on fertilization, embryonic development, biomineralization, metabolism, immune response, foraging, anti-predation, habitat selection, and the social hierarchy of marine animals. This is an important resource for researchers and practitioners in marine conservation, marine wildlife studies, and climate change studies. In addition, it will serve as a valuable text for marine biology and animal science students. - Examines the impacts of carbon dioxide increases in the world's oceans relating to marine vertebrates and invertebrates - Identifies environmental factors, including climate change and pollution and how they increase the negative effects of ocean acidification - Facilitates a better understanding of ocean acidification effects for conservationism and future prevention

Book Description
This book brings together the state of our knowledge on the interactions between climate change and marine biota. It focusses broadly on the environmental stressors during the Anthropocene period; when human activities started to have a significant global impact on earth's geological imprint and ecosystems. This period of rapid change is accompanied by rising carbon dioxide levels, increasing global temperatures, loss of oxygen in aquatic systems, and the fast release of pollutants into the environment among many other environmental stressors originating from large scale human activities, such as widespread overfishing.The Future of Marine Life in a Changing Ocean starts by providing the reader with a brief background on fundamental concepts in ocean science and climate. It then moves on to a brief description of recent changes in marine chemistry such as ocean acidification, a decline in oxygen levels in the oceans, ocean warming, and marine pollution, with some examples of shifts in ecosystem diversity. The chapters discuss these topics in the context of how a changing ocean impacts ecosystem health, the biological carbon pump, the sequestration of carbon dioxide from the surface ocean into the deep sea, and the perceived notion of the ocean's unlimited resilience to maintain its role as a 'carbon reservoir'. Topics include threats to marine diversity, ecosystem function, latitudinal shifts in productivity and diversity, and changes in global cycling of elements such as carbon. It concludes with an analysis of the impact of climate change on food security.Written for undergraduate and graduate students, and researchers in the natural and social sciences, this book provides a science background to study environmental change in marine ecosystems as well as a science framework to study policy, marine law and the economics of climate change. This book is an essential read for anyone hoping to understand key challenges facing our oceans.

Book Description
Evidence and logic are lacking in many areas of public debate today on hot-button issues ranging from dietary fat to vaccination. In Science Under Attack, Dr. Alexander shows how science is being abused, sidelined or ignored, making it difficult or impossible for the public to form a reasoned opinion about important issues. Readers will learn why science is becoming more corrupt, and also how it is being abused for political and economic gain, support of activism, or the propping up of religious beliefs. To illustrate how science is being ignored and abused, the author examines six different issues and the way they are currently discussed: evolution, dietary fat, climate change, vaccination, GMO crops and continental drift. In his research, he has gone back to the original source wherever possible rather than quoting second-hand sources, adding a degree of accuracy and nuance often missing. The controversial assertion that science does not support the conventional wisdom on climate change should be of particular interest. Alexander shows that the scientific evidence for a substantial human contribution to climate change is actually flimsy, and he demonstrates the fallacy of comparing the strong link between smoking and lung cancer to the much weaker connection between human activity and global warming.

Book Description
The marine world is an immense, three-dimensional living space inhabited by marine life that varies from the mundane to the bizarre. Its salty influence extends up river estuaries, over seashores and inland with brine-laden spray. The Marine World covers all those organisms that live in, on and around the ocean bringing together in a single text everything from the miniscule to the immense. With chapters on marine bacteria, plants, fungi and protozoa, as well as all the major groups of marine invertebrates, plus fish, reptiles, mammals and birds, it provides an insight into the existence and way of life of almost everything living in the ocean. Each animal or plant is found in its own particular place and The Marine World encompasses principal ocean habitats and ecosystems including open water, seashores, deep sea, coral reefs and many more. Written with clear, accessible text and illustrated throughout with photographs and detailed drawings, The Marine World provides in depth information to provide answers for each group on 'what?' 'where?' and 'how?', via sections on identification, distribution, structure, biology, classification and conservation.
