Download or read book Sturgeon Fishes written by Tatiana A. Dettlaff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive description of development of the Acipenserid fish published in the English language. It con tains the results of more than 40 years of studies by the authors and their colleagues. My own life in science has been intimately related both with the authors and the fish, which are the subject of this book. Therefore, it gives me a great pleasure to present to the English reader an expanded version of the book. Those interested in the history of biology must be well aware of the fact that genetics in the USSR was practically demolished by Lysenko at the session of the Lenin All-Union Academy of Agricultural Sciences in 1948. However, it is much less well known that other fundamental branches of biology were also persecuted at that time, experimental embryology (developmental mechanics) among them. As a result, many embryologists, in cluding the authors of this book, were forced to turn to more ap plied problems, this being the only way to continue research. They had to abandon amphibians and concentrate their efforts on sturgeon.

Download or read book Imperiled Ocean written by Laura Trethewey and published by Simon and Schuster. This book was released on 2019-11-12 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: On a life raft in the Mediterranean, a teenager from Ghana wonders whether he will reach Europe alive. A young chef disappears from a cruise ship, leaving a mystery for his friends and family to solve. A water-squatting community battles eviction from a harbor in a Pacific Northwest town, raising the question of who owns the water. Imperiled Ocean is a deeply reported work of narrative journalism that follows people as they head out to sea. What they discover holds inspiring and dire implications for the life of the ocean, and for all of us back on land. As Imperiled Ocean unfolds, battles are fought, fortunes made, and lives are lost. Behind this human drama, the ocean is growing ever more unstable, threatening to upend life on land. We meet a biologist tracking sturgeon who is unable to stop the development and pollution destroying the fish’s habitat, he races to learn about the fish before it disappears. Sturgeon has survived more than 300 million years on earth and could hold important truths about how humanity might make itself amenable to a changing ocean. As a fisher and scientist, his ability to listen to the water becomes a parable for today. By eavesdropping on an imperiled world, he shows a way we can move forward to save the oceans we all share.
Download or read book Otters written by Hans Kruuk and published by OUP Oxford. This book was released on 2006-08-17 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Otters are highly charismatic and popular animals of very considerable concern to conservationists worldwide. Written by the pre-eminent authority in the field, this book builds on the reputation of the author's landmark monograph of the European otter, Wild Otters (OUP, 1995). Furthermore, its broader scope to include all species of otter in North America as well as Europe and elsewhere leads to a deeper synthesis that greatly expands the book's overall relevance and potential readership. Aimed at naturalists, scientists and conservationists, its personal style and generously illustrated text will appeal to amateurs and professionals alike. It emphasises recent research and conservation management initiatives for all 13 species of otter worldwide, incorporates recent molecular research on taxonomy and population genetics, and discusses the wider implications of otter studies for ecology and conservation biology. As well as enchanting direct observations of the animals, there is guidance about how and where to watch and study them. From otters in the British and American lakes and rivers, to sea otters in the Pacific Ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an engaging approach to their fascinating existence, to the science needed to understand it, and to the very real threats to their survival.
Download or read book Creative Conservation written by P.J. Olney and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Past progress and future challenges R.J. Wheater Royal Zoological Society of Scotland, Edinburgh, UK. In the past two decades much has been achieved in the sphere of breeding endangered species, and we should be pleased that our co operative efforts have already borne so much fruit. However, on balance and despite the best efforts of conservationists, the position of wildlife in the wild places where they are best conserved has become worse, often dramatically worse. Before returning to the United Kingdom in 1972, I was in Uganda for 16 years, most of which time was spent as Chief Warden of Murchison Falls National Park. Our main problem was that an over-population of large mammals was having a devastating impact on the habitat. Devas tation was being wrought on woodland areas by the arrival of large numbers of elephants into the sanctuary of the Park, following changes in land use in the areas outside the Park. These changes were in response to the requirements of an ever-expanding human population.

Available in PDF, EPUB and Kindle. Book excerpt: The collapse of many of the World’s fisheries continues to be of major concern and the enhancement of fish stocks through techniques such as ranching is of huge importance and interest across the globe. This important book, which contains fully peer reviewed and carefully edited papers from the 2nd International Symposium in Stock Enhancement and Sea Ranching is broadly divided into sections covering the following areas: The present situation of stock enhancement Seed quality and techniques for effective stocking Health management of hatchery stocks Methods for evaluating stocking effectiveness Population management in stock enhancement and sea ranching Management of stocked populations Ecological interactions with wild stocks Genetic management of hatchery and wild stocks Socio-economics of stock enhancement Case studies Stock Enhancement and Sea Ranching has been written and edited by some of the world’s foremost authorities in fisheries science and related areas and is essential reading for all fisheries scientists throughout the World. Fish biologists, marine and aquatic scientists, environmental biologists, ecologists, conservationists, aquaculture personnel and oceanographers will all find much of use and interest within this book. All libraries within universities and research establishments where these subjects are studied and taught should have copies of this book on their shelves.

Download or read book Fisheries Ecology and Management written by Carl J. Walters and published by Princeton University Press. This book was released on 2020-06-30 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses, and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management, this useful guide will also be widely read by ecologists and fisheries scientists.
