The hadal zone represents one of the last great frontiers in marine science, accounting for 45% of the total ocean depth range. Despite very little research effort since the 1950s, the last ten years has seen a renaissance in hadal exploration, almost certainly as a result of technological advances that have made this otherwise largely inaccessible frontier, a viable subject for research. Providing an overview of the geology involved in trench formation, the hydrography and food supply, this book details all that is currently known about organisms at hadal depths and linkages to the better known abyssal and bathyal depths. New insights on how, where and what really survives and thrives in the deepest biozone are provided, allowing this region to be considered when dealing with sustainability and conservation issues in the marine environment.
A long overdue collation of all that is known about life in the trenches and the hadal communities therein.
The Sapphire has risen. There are rumors in Adlivun that the dead queen walks among her people once again… Aazuria Vellamo has returned to the undersea kingdom of Adlivun only to find that the place she called home for over five hundred years has changed drastically. Once the beloved rightful queen, she is now an outcast hiding among the commoners. She observes the political situation from a distance, trying to maneuver her daughter into the safest place possible-- but Aazuria quickly discovers that no part of the expanding nation is safe any longer. Mingling with the lower class workers who have been forced to labor on building a transpacific bridge across the Bering Strait, Aazuria watches her people suffer disgrace and abuse at the hands of their American overseers. Before she realizes it, she finds herself mixed up in riots and rebellions. Aazuria goes about in disguise to learn more, and discovers that in Adlivun's desperate underbelly a religious cult has formed, led by Mother Melusina. Her own dear friend, General Visola Ramaris, has been training a small group of elite warriors in her own private army, which is all that remains of Adlivun's fine military. Visola's husband, Vachlan Suchos, learns that he has missed important information coded in the words which he only considered an emotional farewell from his dying daughter. This intelligence will inevitably lead to the awakening of the vicious man's inner beast, and inspire his lust for war. But with Adlivun completely reliant on protection from the United States-- is it a good idea to burn bridges?
This is a special volume on ocean biogeography containing chapters bringing the wealth of knowledge of Russian scientists to a global audience. Ocean biogeography was the subject of much marine research carried out by the former USSR, where extensive facilities were provided on a world-wide scale. Volume 32 is devoted to the geographical and vertical distribution of life in the open oceans, including the great depths. The contributions range widely from plankton and squid to the bottom fauna of the bathyal, abyssal, and hadal zones. This volume will help bridge the gap between Russian and western marine biogeographers and will be of interest to a wide range of marine biologists. Advance in Marine Biology contains up-to-date reviews of all areas of marine science, including fisheries, science and macro/micro fauna. Each volume contains peer reviewed papers detailing the ecology of marine regions.
This book entitled “Ocean and Coastal Ecology” under the series of 21st Century Biology and Agriculture has 10 chapters aimed to provide a clear understanding on scientific principles of marine ecology in order to manage the marine environment and its bio-resources in view of deterioration of marine ecosystems, natural calamities and climate change. This book would be of immense help to students, scholars and all others interested in marine ecology.
Through nine successful editions, and for over 45 years, Biogeography: An Ecological and Evolutionary Approach has provided a thorough and comprehensive exploration of the varied scientific disciplines and research that are essential to understanding the subject. The text, noted for its clear and engaging style of writing, has been praised for its solid background in historical biogeography and basic biology, that is enhanced and illuminated by discussions of current research. This new edition incorporates the exciting changes of the recent years and presents a thoughtful exploration of the research and controversies that have transformed our understanding of the biogeography of the world. New themes and topics in this tenth edition include: Next generation genetic technologies and their use in historical biogeography, phylogeography and population genomics Biogeographical databases and biodiversity information systems, which are becoming increasingly important for biogeographical research An introduction to functional biogeography and its applications to community assembly, diversity gradients and the analysis of ecosystem functioning Updated case studies focusing on island biogeography, using the latest phylogenetic studies Biogeography: An Ecological and Evolutionary Approach reveals how the patterns of life that we see today have been created by the two great Engines of the Planet: the Geological Engine, plate tectonics, which alters the conditions of life on the planet, and the Biological Engine, evolution, which responds to these changes by creating new forms and patterns of life.
Textbook of Environmental Chemistry provides fundamental knowledge of the principles of environment and its chemistry to students as well as teachers of Environmental Sciences, Environmental Chemistry and Environmental Studies at graduate, postgraduate, polytechnic, and engineering levels. This book is also useful for the students and professors of general science. The book explores biological resources and their relationships with physical and chemical aspects of the environment. Due emphasis has been given to the regional as well as global environmental problems like water, air, soil and noise pollution, their types and sources, and their effects on the ecosystem.
