Book excerpt: Fishes of the Salish Sea is the definitive guide to the identification and history of the marine and anadromous fishes of Puget Sound and the Straits of Georgia and Juan de Fuca. This comprehensive three-volume set, featuring striking illustrations of the Salish Sea's 260 fish species by noted illustrator Joseph Tomelleri, details the ecology and life history of each species and recounts the region's rich heritage of marine research and exploration. Beginning with jawless hagfishes and lampreys and ending with the distinctive Ocean Sunfish, leading scientists Theodore Wells Pietsch and James Orr present the taxa in phylogenetic order, based on classifications that reflect the most current scientific knowledge. Illustrated taxonomic keys facilitate fast and accurate species identification. These in-depth, thoroughly documented, and yet accessible volumes will prove invaluable to marine biologists and ecologists, natural resource managers, anglers, divers, students, and all who want to learn about, marvel over, and preserve the vibrant diversity of Salish Sea marine life.

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 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.

Book excerpt: Dans un passé assez récent, un intérêt sans précédent s'est développé concernant les ressources globales. Nous nous rendons maintenant compte que les ressources biologiques sont loin d'être illimitées et pendant les dernières décennies du 20ème siècle, des efforts ont débuté pour contrôler nos usages de l'environnement et qui agissent les uns avec les autres dans les écosystèmes dont nous dépendons finalement. Le projet "Mers au millénaire": Une Evatuation Environmentale sur la zone côtière couvre le secteur où vit plus d'un quart de l'humanité, et jusque au bas du plateau continental. Ces trois livres se concentrent sur la biosphère où les interactions de l'homme avec les mers et leurs systèmes biologiques et physiques sont le plus sensibles. 135 chapitres écrits par les experts internationaux et les scientifiques travaillant dans ce domaine offrent un sommaire unique des mers et des océans du monde. À la fin du millénaire les auteurs à travers le monde ont examiné l'état de nos habitats marins et côtiers. Pour la première fois, ils ont uni leurs efforts de par le monde pour s'assurer que ces habitats restent dans un état de fonctionnement durable et stable; l'information a été documentée et assemblée dans une source bibliographique unique. "Mers au millénaire" fournit aux scientifiques dans le monde entier une occasion unique pour s'enrichir de toutes ces expériences. Les trois volumes de "Mers au millénaire" couvrent des chapîtres d'importance globale et régionale comme : description biologique des eaux côtières et du plateau continental; développement et utilisation de la zone côtière; effets des dragages et autres techniques d'accrétion sédimentaire; effet dans le temps des déversement de polluants;de pêche; méthodes et techniques de gestion utilisées pour gérer en continu les écosystèmes. Plus de 800 figures comprenant des cartes, les graphiques, les dessins au trait et les photograph.
