Book Description
The impact of man on the biosphere is profound. Quite apart from our capacity to destroy natural ecosystems and to drive species to extinction, we mould the evolution of the survivors by the selection pressures we apply to them. This has implications for the continued health of our natural biological resources and for the way in which we seek to optimise yield from those resources. Of these biological resources, fish stocks are particularly important to mankind as a source of protein. On a global basis, fish stocks provide the major source of protein for human consumption from natural ecosystems, amounting to some seventy million tonnes in 1970. Although fisheries management has been extensively developed over the last century, it has not hitherto considered the evolutionary consequences of fishing activity. While this omission may not have been serious in the past, the ever increasing intensity of exploitation and the deteriorating health of fish stocks has generated an urgent need for a better understanding of evolution driven by harvesting and the implications of this for fish stock management. The foundations for this understanding for the most part come from recent developments in evolutionary biology and are not generally available to fisheries scientists. The purpose of this book is to provide this basis in a form that is both accessible and relevant to fisheries biology.

Book Description
Individuals' rights to use natural resources have long existed. This book traces the historical development of these rights and looks at how individuals' rights have evolved. Each chapter focuses on a single natural resource property right, noting the impact of technology, the role of the common law courts, and the increasing role of government.

Book Description
This volume contains the papers presented at a symposium on popula tion biology sponsored by the Deutsche Forschungsgemeinschaft. It was . held at the guest house of the University of Ttibingen at Oberjoch on May 15-19, 1983. Prior to this conference a small group of European biologists had met in Berlin (June 1981) and Pavia (September 1982) to discuss re search problems on the borderline between population genetics and evolutionary ecology. From the contributions and discussions at these meetings it became evident that the unification of approaches to evolutionary problems in population genetics and evolutionary ecology has not yet been suc cessful and requires further efforts. It was the consensus that a larger symposium with international participation would be helpful to con front and discuss the different approaches to population biology in order to assess "where we are now" and "where we should be going. " As a result an organizational committee was formed (F. Christiansen, S. Jayakar, V. Loeschcke, W. Scharloo, and K. W6hrmann) to iden tify topics that seemed, at least to them, to be fruitful in tackling problems in population biology. Consequently, a number of colleagues were asked to participate in the meeting. We have divided this book into chapters corresponding to the eight topics chosen. The volume begins with the relation between genotype and phenotype and is followed by a chapter on quantitative genetics and selection in natural populations.

Book Description
Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.

Book Description
"Historical Evolution of Perceptions of Muslims" offers a comprehensive exploration of how societal perceptions of Muslims have evolved over centuries. Through a meticulous examination of historical events, cultural interactions, and socio-political shifts, this book uncovers the complexities and transformations in the portrayal of Muslims across different eras. From the early formation of perceptions during the rise of Islam to contemporary global challenges, the book provides insights into how these perceptions have influenced and been influenced by the broader historical and cultural contexts. By delving into the impact of major historical events, including the Crusades, the Ottoman Empire's role, colonialism, and modern geopolitical developments, this work aims to shed light on the nuanced realities behind the often-misunderstood image of Muslims, offering readers a deeper understanding of their place in global history and contemporary society.

Book Description
This landmark book offers a comprehensive analysis of how development approaches have evolved since World War II, examining and also evaluating the succession of theories, doctrines, and practices that have been formulated and applied in the Third World and beyond. Covering all developing regions, the book offers an integrated approach for considering the entwined aspects of development: governance, economics, foreign assistance, civil society, and the military. With reference to carefully chosen case studies, the authors offer distinctive explanations for why development approaches fall short and systematically relate the evolution of development thinking to current challenges, identifying the strengths and weaknesses of key institutions and the clashes of institutional interests that have distorted otherwise sound doctrines and negatively affected development practice. In identifying the dynamics that account for shortcomings in past development attempts, and recommending a better integration of doctrines across the entire range of inter-connected development fronts, the book points to how development practice may be improved to better advance human dignity.

Book Description
Natural resources law is a dynamic field of practice, with a rich history that reaches back several centuries. The authors look at current challenges and offer ideas about the future while demonstrating that the federal government's role continues to be a complex one as markets and private actors become more visible participants in the current policy arena. Part I provides foundational analyses of the law, while the second part reviews thematic issues in the area.

Book Description
Fish are one of the most important global food sources, supplying a significant share of the world’s protein consumption. From stocks of wild Alaskan salmon and North Sea cod to entire fish communities with myriad species, fisheries require careful management to ensure that stocks remain productive, and mathematical models are essential tools for doing so. Fish Ecology, Evolution, and Exploitation is an authoritative introduction to the modern size- and trait-based approach to fish populations and communities. Ken Andersen covers the theoretical foundations, mathematical formulations, and real-world applications of this powerful new modeling method, which is grounded in the latest ecological theory and population biology. He begins with fundamental assumptions on the level of individuals and goes on to cover population demography and fisheries impact assessments. He shows how size- and trait-based models shed new light on familiar fisheries concepts such as maximum sustainable yield and fisheries selectivity—insights that classic age-based theory can’t provide—and develops novel evolutionary impacts of fishing. Andersen extends the theory to entire fish communities and uses it to support the ecosystem approach to fisheries management, and forges critical links between trait-based methods and evolutionary ecology. Accessible to ecologists with a basic quantitative background, this incisive book unifies the thinking in ecology and fisheries science and is an indispensable reference for anyone seeking to apply size- and trait-based models to fish demography, fisheries impact assessments, and fish evolutionary ecology.
