Atlas based on censuses conducted from ships and aircraft over waters of the Gulf of Alaska and eastern Bering Sea.

"Compilation of seabird species accounts for all seabirds breeding in Alaska and five important nonbreeders. Conservation status, life history, distribution, population size and trends, conservation concerns, and recommended management actions are included in the accounts"--Leaf i.

Originally published in 1986, this book is concerned with the ways in which seabirds function as predators in the marine environment; in particular about how they find and catch food and how much of it they consume. It reviews both the feeding ecology of seabirds (including adaptations for flight and diving) and also most of the leading field studies (in polar, temperate and tropical regions) that have quantitatively examined the interactions of seabird communities with their prey.

Written for anyone who works with chemicals or has a general interest in ecology, this book examines the interrelationship of life forms in our environment and provides straightforward explanations about the complicated interactions among nature and humans. Emphasizing basic concepts, definitions, and descriptions, the author presents illustrative problems in terms of commonly used ecological parameters to provide readers with enough information to make technical and personal decisions about ecology. Funneling the broad, multidisciplinary field of ecology, which incorporates aspects of biology, chemistry, physics, geology, meteorology, agriculture, forestry, and more into a single stream, the author provides those with backgrounds in only a handful, or even none, of these disciplines with an easy-to-read understanding of the functions and values of ecology and its interrelationships with other sciences, including ecology's direct impact on our lives. Organized into three parts, this book examines the fundamentals of ecology, the role of biodiversity, and the practical side of ecology. Readers will examine such topics as biogeochemical cycles, ecological pyramids, and the laws of population ecology. They will also examine species, terrestrial ecosystems, and aquatic systems. Each chapter ends with a Chapter Review Test.
