This book was released on 2020-06-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and estuarine environments at the interface of terrestrial and marine areas are among the most productive in the world. However, since the beginning of the industrial era, these ecosystems have been subjected to strong anthropogenic pressures intensified from the second half of the 20th century, when there was a marked acceleration in the warming (climate change) of the continents, particularly at high latitudes. Coastal ecosystems are highly vulnerable to alteration of their physical, chemical and biological characteristics (marine intrusion, acidification of marine environments, changes in ecosystems, evolution and artificialization of the coastline, etc.).In contact with heavily populated areas, these environments are often the receptacle of a lot of chemical and biological pollution sources that significantly diminish their resilience. In this context of accelerated evolution and degradation of these areas important for food security of many populations around the world, it is necessary to better identify the factors of pressure and understand, at different scales of observation, their effects and impacts on the biodiversity and on the socio-eco-systems, in order to determine the degree of vulnerability of these coastal ecosystems and the risks they face. A transdisciplinary and integrated approach is required to prevent risks. Within this framework, operational coastal oceanography occupies an important place but also the implementation of a true socio-eco-system approach in order to set up an environmentally friendly development.

Available in PDF, EPUB and Kindle. Book excerpt: Salmonids represent the primary coldwater fishes of culture interest in the world today; species discussed in this work were selected on the basis of their importance to the aquaculture community.

Download or read book Wildlife-habitat Relationships in Oregon and Washington written by David H. Johnson and published by . This book was released on 2001 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides information about the terrestrial, freshwater, and marine habitats of Oregon and Washington and the wildlife that depend upon them; it also supports broader and more consistent conservation planning, management, and research. The 27 chapters identify 593 wildlife species, define some 300 wildlife terms, profile wildlife communities, review introduced and extirpated species and species at risk, and discuss management approaches. The volume includes color and bandw photographs, maps, diagrams, and illustrations; and the accompanying CD-ROM contains additional wildlife data (60,000 records), maps, and seven matrixes that link wildlife species with their respective habitat types. Johnson is a wildlife biologist, engineer, and habitat scientist; and O'Neill is director of the Northwest Habitat Institute; they worked together on this publication project as its managing directors.

This book was released on 2013-04-17 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the compiling of this book, the vast literature dealing with the descriptive morphology, histology and cytology of teleost development has been combed and integrated. The book is divided into 21 chapters, starting with the egg and embryonic development up to hatching. This is followed by a description of ectodermal, mesodermal and entodermal derivatives and the development of various organs. The subject index, species index and the abundant illustrations add extra value to this long awaited book. Developmental Biology of Teleost Fishes will be a valuable tool for scientists and students in the fields of biology, developmental biology, molecular biology and fish biology.

Download or read book Wildlife Ecotoxicology written by John E. Elliott and published by Springer Science & Business Media. This book was released on 2011-08-27 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

Download or read book The Welfare of Fish written by Tore S. Kristiansen and published by Springer Nature. This book was released on 2020-07-01 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates how fish experience their lives, their amazing senses and abilities, and how human actions impact their quality of life. The authors examine the concept of fish welfare and the scientific knowledge behind the inclusion of fish within the moral circle, and how this knowledge can change the way we treat fish in the future. In many countries fish are already protected by animal welfare legislation in the same way as mammals, but in practice there is still a major gap between how we ethically view these groups and how we actually treat them. The poor treatment of fish represents a massive animal welfare problem in aquaculture and fisheries, both in terms of the number of animals affected and the severity of the welfare issues. Thanks to its interdisciplinary scope, this thought-provoking book appeals to professionals, academics and students in the fields of animal welfare, cognition and physiology, as well as fisheries and aquaculture management.

Download or read book Cryopreservation of Fish Gametes written by Judith Betsy and published by Springer Nature. This book was released on 2020-06-27 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the reproductive physiology and endocrinology of fishes is essential for captive maturation and seed production in the field of aquaculture. Studying the spermatology of fishes is a comparatively new focus in aquaculture, which has emerged as an important area of fish research over the past two decades. In this regard, the cryopreservation of fish gametes is a crucial aspect. Moreover, energetics studies of gametes have become essential, considering the loss of vigour in the spermatozoa after cryopreservation.The latest development in this context is the cryopreservation of spermatogonial stem cell, which is also covered in the book, along with detailed information on embryo cryopreservation in fishes and crustaceans. The role of cryopreservation in conservation programmes is another important aspect, one that will especially interest biologists.This book addresses central issues in fish gamete cryopreservation and breeding, while also reviewing the history of cryopreservation. Its most unique feature is the breadth of its coverage, from basic information on reproduction in fishes, to such advanced topics as embryo cryopreservation. Chiefly intended as a handy troubleshooting guide, the book represents a valuable resource for research students in related fields.
