Book Description
The past decade has seen a huge increase in the interest and attention directed toward sea ducks, the Mergini tribe. This has been inspired, in large part, by the conservation concerns associated with numerical declines in several sea duck species and populations, as well as a growing appreciation for their interesting ecological attributes. Reflecting the considerable research recently conducted on this tribe, Ecology and Conservation of North American Sea Ducks examines the 15 extant species of sea ducks from North America. Chapters are organized conceptually to focus on, compare, and contrast the ecological attributes of the tribe. Experts provide in-depth treatments of a range of topics, including: Population dynamics and genetics Infectious diseases and parasites Breeding costs and cross-seasonal affects Contaminant burdens Foraging behavior and energetics Migration strategies, molt ecology, and habitat affinities and dynamics Breeding systems and reproductive behavior Harvest history The book presents a comprehensive synthesis of sea duck ecology, documents factors that have caused population declines of some species, and provides managers with measures to enhance recovery of depressed populations of sea ducks in North America. Capturing the current state of knowledge of this unique tribe, it provides a benchmark for where we are in conservation efforts and suggests future directions for researchers, managers, students, conservationists, and avian enthusiasts.

Book Description
“A groundbreaking work about race and the American landscape, and a deep meditation on nature…wise and beautiful.”—Helen Macdonald, author of H is for Hawk A Foreword Reviews Best Book of the Year and Nautilus Silver Award Winner In me, there is the red of miry clay, the brown of spring floods, the gold of ripening tobacco. All of these hues are me; I am, in the deepest sense, colored. Dating back to slavery, Edgefield County, South Carolina—a place “easy to pass by on the way somewhere else”—has been home to generations of Lanhams. In The Home Place, readers meet these extraordinary people, including Drew himself, who over the course of the 1970s falls in love with the natural world around him. As his passion takes flight, however, he begins to ask what it means to be “the rare bird, the oddity.” By turns angry, funny, elegiac, and heartbreaking, The Home Place is a meditation on nature and belonging by an ornithologist and professor of ecology, at once a deeply moving memoir and riveting exploration of the contradictions of black identity in the rural South—and in America today. “When you’re done with The Home Place, it won’t be done with you. Its wonders will linger like everything luminous.”—Star Tribune “A lyrical story about the power of the wild…synthesizes his own family history, geography, nature, and race into a compelling argument for conservation and resilience.”—National Geographic

Book Description
Conservation of Marine Birds is the first book to outline and synthesize the myriad of threats faced by one of the most imperiled groups of birds on earth. With more than half of all 346 seabird species worldwide experiencing population declines and 29% of species recognized as globally threatened by the International Union for Conservation of Nature, the timing to determine solutions to threats could not be more urgent. Written by a diverse team of international experts on marine birds, this book explores the environmental and biogeographical factors that influence seabird conservation and provides concrete recommendations for mounting climate change issues. This book will be an important resource for researchers and conservationists, as well as ecologists and students who want to understand seabirds, the threats they are facing, and tactics to help conserve and protect them. Outlines both threats and solutions in the marine and terrestrial realm Synthesizes information to provide a comprehensive strategy moving forward, especially considering climate change Created by a team of experts with the latest and most comprehensive knowledge of seabird conservation

Book Description
The human history of depicting birds dates to as many as 40,000 years ago, when Paleolithic artists took to cave walls to capture winged and other beasts. But the art form has reached its peak in the last four hundred years. In The Art of the Bird, devout birder and ornithologist Roger J. Lederer celebrates this heyday of avian illustration in forty artists’ profiles, beginning with the work of Flemish painter Frans Snyders in the early 1600s and continuing through to contemporary artists like Elizabeth Butterworth, famed for her portraits of macaws. Stretching its wings across time, taxa, geography, and artistic style—from the celebrated realism of American conservation icon John James Audubon, to Elizabeth Gould’s nineteenth-century renderings of museum specimens from the Himalayas, to Swedish artist and ornithologist Lars Jonsson’s ethereal watercolors—this book is feathered with art and artists as diverse and beautiful as their subjects. A soaring exploration of our fascination with the avian form, The Art of the Bird is a testament to the ways in which the intense observation inherent in both art and science reveals the mysteries of the natural world.

Book Description
The sustainable exploitation of the marine environment depends upon our capacity to develop systems of management with predictable outcomes. Unfortunately, marine ecosystems are highly dynamic and this property could conflict with the objective of sustainable exploitation. This book investigates the theory that the population and behavioural dynamics of predators at the upper end of marine food chains can be used to assist with management. Since these species integrate the dynamics of marine ecosystems across a wide range of spatial and temporal scales, they offer new sources of information that can be formally used in setting management objectives. This book examines the current advances in the understanding of the ecology of marine predators and will investigate how information from these species could be used in management.

Book Description
A Silent Spring for oceans, written by "the Rachel Carson of the fish world" (The New York Times) Who can forget the sense of wonder with which they discovered the creatures of the deep? In this vibrant hymn to the sea, Callum Roberts—one of the world’s foremost conservation biologists—leads readers on a fascinating tour of mankind’s relationship to the sea, from the earliest traces of water on earth to the oceans as we know them today. In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life. We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

Book Description
Contributors to this volume offer new research on extinction processes in birds, nest predation, and song systems, and describes a graphical model that helps predict the reproductive consequences of time allocation between the competing demands of guarding young birds and foraging for food. Current Ornithology is the only English-language publication currently devoted exclusively to extensive reviews and synthesis of topics pertaining to all aspects of the biology of birds. Chapters fall under such diverse rubrics as ecology, evolution, behavior, phylogeny, behavioral ecology, anatomy and physiology, and conservation biology. All authors are leading authorities on their subjects, and each chapter is refereed by experts in the topics covered. Although all chapters focus primarily on birds, some topics, such as the social cognition of birds as compared to primates (Volume 13), have significant application to disciplines outside of ornithology. Current Ornithology aims to provide an accessible, up-to-date, accurate source of data and to contribute to conceptual generalization and unification across the biological sciences.
