Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.

Download or read book Ecology written by Charles J. Krebs and published by Benjamin-Cummings Publishing Company. This book was released on 2001 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

Download or read book The Future of Money written by Bernard A. Lietaer and published by Random House Business Books. This book was released on 2013-02-01 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE GLOBAL MONEY SYSTEM NO LONGER WORKS IN OUR BEST INTERESTS; WE NEED A SERIOUS OVERHAUL OF MONEY - AND OF OUR ATTITUDE TOWARDS IT. Based on the four mega-trends of monetary instability, global greying (an ageing global population), the information revolution, and climate change, Bernard Lietaer looks at different scenarios of what the world might be like in 2020. The Corporate Millennium: governments are disbanded, central banks become irrelevant and the world is run with Big Brother control by huge companies with their own currencies. CARING COMMUNITIES: after a monetary crash, people retreat into small, self-sustaining communities, like tribes. HELL ON EARTH: in which the breakdown of life as we know it is followed by a highly individualistic free-for-all, resulting in an ever more obscene gulf between rich and poor. SUSTAINABLE ABUNDANCE: envisages a world where we take better care of the environment, re-engage the poor and the unemployed in mainstream society and give back time and fulfilment to the over-worked, while providing the elderly with a high level of personal care. A society of sustainable abundance is achievable - but only if we are willing to re-think our money system and use money innovations that have already proven effective somewhere in the world today.

Download or read book Ethology and Behavioral Ecology of Sea Otters and Polar Bears written by Randall W. Davis and published by Springer. This book was released on 2022-07-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

Download or read book The Bering Sea Ecosystem written by National Research Council and published by National Academies Press. This book was released on 1996-05-08 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bering Sea, which lies between the United States and Russia, is one of the most productive ecosystems in the world and has prolific fishing grounds. Yet there have been significant unexplained population fluctuations in marine mammals and birds in the region. The book examines the Bering Sea ecosystem's dynamics and the relationship between man and the ecosystem, in order to identify potential reasons for the population fluctuations as well as identify ways the Sea's living resources can be better managed by government.

Download or read book The Sex Imperative written by Kenneth E. Maxwell and published by Springer. This book was released on 2013-11-11 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The sex imperative - the irresistible impulse to engage in sexual relations - has enabled animals to share their genes and evolve. Maxwell traces the progress of sex from the simple sharing of genes between cells to the elaborate courtship rituals that developed so sperm could merge with egg. In the effort to join sperm and egg, species have developed some astounding and unusual sexual adaptations. As Maxwell vividly describes the sex lives of various creatures, he attests to the resiliency and amazing adaptability of life to its everchanging environment. By focusing on the diversity of animal sexual relationships, Maxwell enables us to question the very basis of sexuality: What is sex? Why did it evolve? How does sexuality and survival shape the social behavior of animals and humans? The sex imperative is indeed the driving force behind Darwin's theory of random variation and natural selection, better known as "survival of the fittest." Maxwell goes so far as to investigate our latest accomplishment in the science of begetting offspring: genetic engineering." "This awe-inspiring and unique work celebrates the power and wonder of life and sexuality of all creatures - including humans. After reading this engrossing and illuminating work, no one will ever think of evolution in the same way."--Jacket

Download or read book Archaeomineralogy written by George R. Rapp and published by Springer Science & Business Media. This book was released on 2002-05-14 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1.1 Prologue What is archaeomineralogy? The term has been used at least once before (Mitchell 1985), but this volume is the first publication to lay down the scientific basis and systematics for this subdiscipline. Students sometimes call an introductory archaeology course "stones and bones." Archaeomineralogy covers the stones component of this phrase. Of course, archaeology consists of a great deal more than just stones and bones. Contemporary archaeology is based on stratigraphy, geomorphology, chronometry, behavioral inferences, and a host of additional disciplines in addition to those devoted to stones and bones. To hazard a definition: archaeomineralogy is the study of the minerals and rocks used by ancient societies over space and time, as implements, orna ments, building materials, and raw materials for ceramics and other processed products. Archaeomineralogy also attempts to date, source, or otherwise char acterize an artifact or feature, or to interpret past depositional alteration of archaeological contexts. Unlike geoarchaeology, archaeomineralogy is not, and is not likely to become, a recognized subdiscipline. Practitioners of archaeomineralogy are mostly geoarchaeologists who specialize in geology and have a strong background in mineralogy or petrology (the study of the origin ofrocks).
