Book Description
Global changes, including climate change and intensive fishing, are having significant impacts on the world's oceans. This book advances knowledge of the structure and functioning of marine ecosystems and their major sub-systems, and how they respond to physical forcing.

Book Description
GLOBEC (GLOBal ocean ECosystems dynamics) is a research initiative proposed by the oceanographic and fisheries communities to address the question of how changes in global environment are expected to affect the abundance and production of animals in the sea. The approach to this problem is to develop a fundamental understanding of the mechanisms that determine both the abundance of key marine animal populations and their variances in space and time. The assumption is that the physical environment is a major contributor to patterns of abundance and production of marine animals, in large part because the planktonic life stages typical of most marine animals are intrinsically at the mercy of the fluid motions of the medium in which they live. Consequently, the authors reason that a logical approach to predicting the potential impact of a globally changing environment is to understand how the physical environment, both directly and indirectly, contributes to animal abundance and its variability in marine ecosystems. The plans for this coordinated study of of the potential impact of global change on ocean ecosystems dynamics are discussed. Unspecified Center...

Book Description
During recent years, large-scale investigations into global climate change and other highly visible issues have taken the lion's share of declining research funds. At the same time, funding for basic research in such core disciplines as physical oceanography, biological oceanography, chemical oceanography, and marine geology has dwindled. Global Ocean Science examines how the largest U.S. ocean research programs, such as the Ocean Drilling Program (ODP) and the Joint Global Ocean Flux Study (JGOFS), have significantly contributed to our understanding of the oceans. The book examines the impact of these programs on research, education, and collegiality within this diverse scientific community and offers recommendations to help ensure a vital future for ocean science, including: Specific results of the programs such as data collected, conceptual breakthroughs, information published, demonstrable use of program products, incorporation of new knowledge into education, and contribution to policymaking and decisionmaking by federal agencies. Mechanisms for efficiently identifying knowledge gaps and research questions, strategic planning of research programs, managing competitive proposals, securing needed resources, and more. This practical book will be welcomed by ocean investigators, users of oceanographic research findings, policymakers, administrators, educators, and students.

Book Description
The term "zooplankton" describes the community of floating, often microscopic, animals that inhabit aquatic environments. Being near the base of the food chain, they serve as food for larger animals, such as fish. The ICES (International Council for the Exploration of the Sea) Zooplankton Methodology Manual provides comprehensive coverage of modern techniques in zooplankton ecology written by a group of international experts. Chapters include sampling, acoustic and optical methods, estimation of feeding, growth, reproduction and metabolism, and up-to-date treatment of population genetics and modeling. This book will be a key reference work for marine scientists throughout the world. - Sampling and experimental design - Collecting zooplankton - Techniques for assessing biomass and abundance - Protozooplankton enumeration and biomass estimation - New optical and acoustic techniques for estimating zooplankton biomass and abundance - Methods for measuring zooplankton feeding, growth, reproduction and metabolism - Population genetic analysis of zooplankton - Modelling zooplankton dynamics This unique and comprehensive reference work will be essential reading for marine and freshwater research scientists and graduates entering the field.

Book Description
The Chinese government is increasingly focusing on ecological construction and has subscribed to a national “Ecological Civilization Construction”. Ecological research and protection practice develop so fast and achieve a lot at the national agenda.This book is a synthesis of five most exciting and dominant themes in contemporary ecological research in China: biodiversity, ecosystem management, degraded ecosystem restoration, global change and sustainable development.This book spans all the Earth's major ecosystems, such as forests, oceans, grasslands, wetlands, lakes, rivers, farmland and cities.This book provides a platform for scientific research across a variety of disciplines. It will be invaluable to experts, policymakers and local officers and will also be a highly useful resource for undergraduate and postgraduate students.This book will allow researchers, students and policymakers outside China to learn about the significant achievements and applications of ecological research within China.
