Download or read book Ethology and Behavioral Ecology of Odontocetes written by Bernd Würsig and published by Springer. This book was released on 2019-08-02 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.

Download or read book Adaptive management of fisheries in response to climate change written by ​Bahri, T., Vasconcellos, M., Welch, D.J., Johnson, J., Perry, R.I., Ma, X. & Sharma, R. and published by Food & Agriculture Org.. This book was released on 2021-02-01 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report aims to accelerate climate change adaptation implementation in fisheries management throughout the world. It showcases how flexibility can be introduced in the fisheries management cycle in order to foster adaptation, strengthen the resilience of fisheries, reduce their vulnerability to climate change, and enable managers to respond in a timely manner to the projected changes in the dynamics of marine resources and ecosystems. The publication includes a set of good practices for climate-adaptive fisheries management that have proven their effectiveness and can be adapted to different contexts, providing a range of options for stakeholders including the fishing industry, fishery managers, policymakers and others involved in decision-making. These good practices were linked to one or more of the three common climate-related impacts on fisheries resources: distributional change; productivity change; and species composition change. Therefore, these three impacts can serve as practical entry points to guide decision-makers in identifying good practice adaptation measures suitable for their local contexts. These good practices are based upon transferable experiences and lessons learned from the thirteen case studies across the globe and hopefully will contribute to greater uptake and implementation of climate-adaptive fisheries management measures on the ground.

Marine Resources Service and published by Food & Agriculture Org.. This book was released on 1994 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.

Download or read book Pacific Salmon Life Histories written by Cornelis Groot and published by UBC Press. This book was released on 1991 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

Download or read book Skeena River Fish and Their Habitat written by Allen Gottesfeld and published by Oregon State University Press. This book was released on 2008 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: British Columbia¿s Skeena River is one of the great salmon rivers of the North Pacific. The river and its fish have supported indigenous peoples for thousands of years. More recently, the Skeena has earned world renown for its recreational fishery and magnificent wilderness setting. Yet, over the last century, fish populations have declined from overfishing, habitat alteration and, to an unknown degree, climate change. Development of mining as well as oil and gas resources may also pose threats to fish populations.This book presents the first thorough review of the salmon stocks and freshwater species of the Skeena River. Initial chapters summarize the river¿s environment, fish, and fisheries. The book then examines the physical geography, development history, indigenous use, and major salmon stocks of each of the watershed¿s sub-basins. This volume makes available for the first time¿to researchers, field biologists, fishermen and natural history enthusiasts¿both the published, and largely unpublished, literature on this productive salmon ecosystem.

Download or read book Bears of the World written by Vincenzo Penteriani and published by Cambridge University Press. This book was released on 2020-11-30 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bile bear market. The IUCN lists six bears as vulnerable or endangered, and even the least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bears species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.

Download or read book Marine Mammals in a Changing World written by Alexander J Werth and published by Mdpi AG. This book was released on 2022-01-29 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite tremendous advances in our understanding of marine mammals over the past several decades, numerous unanswered questions remain. These include fundamental questions in every biological discipline as well as other areas of science, including basic and applied chemistry and physics. Current studies of marine mammals reflect major improvements in technology as well as equally large changes in the ocean environment. Contributions for this Special Issue were invited in all areas of marine mammal research, especially those focusing on one (or both) of two themes: changing technological advances and changes in ocean habitats affecting marine mammals (including but not limited to changes in climate/temperature; ocean acidification; noise, plastic, or chemical pollution; vessel traffic and ship strikes; pathogenic viruses and microbes; trophic and salinity changes; fisheries impacts; habitat destruction; and related topics). The five articles published in this Special Issue focus on diverse areas of marine mammal research and health, including ecology, conservation, population biology and management, behavior, habitat and distribution, genetics, evolution, physiology, anatomy, acoustics, effects of noise and pollution, and new technologies.
