Book excerpt: The distribution of adult Pacific herring (Clupea harengue pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by depth and geographic area over 24 successive months during 1973-75. From June through September, schools concentrated at 5- to 37-m depths where zooplankton was abundant, and moderate currents were present in a stratified water column. The schools migrated from this area to wintering grounds in October when windstorms and sinking of cooling surface waters broke up stratification, day length shortened, and food abundance declined drastically. The schools remained near bottom in the deeper parts of the wintering grounds at 52- to 85-m depths into February or March when day length had increased, but temperatures and food abundance remained low. At this time, the herring left the wintering grounds and moved up Lynn Canal to areas near spawning beaches. Pacific herring remained in these areas until water temperatures increased and plankton blooms appeared in late April and May, at which time the fish moved into the shallows and spawned. By early summer, the schools gradually concentrated again on the main feeding grounds. An evaluation of the study design and potential for improvements in similar studies is included.

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. Comprehensive accounts of 260 fish species Brilliant color plates of all treated species Illustrated taxonomic keys for easy species identification In-depth history of Salish Sea research and exploration

Available in PDF, EPUB and Kindle. Book excerpt: This collection of studies by anthropologists, botanists, ecologists, and biologists is an important contribution to the emerging field of historical ecology. The book combines cutting-edge research with new perspectives to emphasize the close relationship between humans and their natural environment. Contributors examine how alterations in the natural world mirror human cultures, societies, and languages. Treating the landscape like a text, these researchers decipher patterns and meaning in the Ecuadorian Andes, Amazonia, the desert coast of Peru, and other regions in the neotropics. They show how local peoples have changed the landscape over time to fit their needs by managing and modifying species diversity, enhancing landscape heterogeneity, and controlling ecological disturbance. In turn, the environment itself becomes a form of architecture rich with historical and archaeological significance. Time and Complexity in Historical Ecology explores thousands of years of ecological history while also addressing important contemporary issues, such as biodiversity and genetic variation and change. Engagingly written and expertly researched, this book introduces and exemplifies a unique method for better understanding the link between humans and the biosphere.

Available in PDF, EPUB and Kindle. Book excerpt: Humanity can make short work of the oceans’ creatures. In 1741, hungry explorers discovered herds of Steller’s sea cow in the Bering Strait, and in less than thirty years, the amiable beast had been harpooned into extinction. It’s a classic story, but a key fact is often omitted. Bering Island was the last redoubt of a species that had been decimated by hunting and habitat loss years before the explorers set sail. As Callum M. Roberts reveals in The Unnatural History of the Sea, the oceans’ bounty didn’t disappear overnight. While today’s fishing industry is ruthlessly efficient, intense exploitation began not in the modern era, or even with the dawn of industrialization, but in the eleventh century in medieval Europe. Roberts explores this long and colorful history of commercial fishing, taking readers around the world and through the centuries to witness the transformation of the seas. Drawing on firsthand accounts of early explorers, pirates, merchants, fishers, and travelers, the book recreates the oceans of the past: waters teeming with whales, sea lions, sea otters, turtles, and giant fish. The abundance of marine life described by fifteenth century seafarers is almost unimaginable today, but Roberts both brings it alive and artfully traces its depletion. Collapsing fisheries, he shows, are simply the latest chapter in a long history of unfettered commercialization of the seas. The story does not end with an empty ocean. Instead, Roberts describes how we might restore the splendor and prosperity of the seas through smarter management of our resources and some simple restraint. From the coasts of Florida to New Zealand, marine reserves have fostered spectacular recovery of plants and animals to levels not seen in a century. They prove that history need not repeat itself: we can leave the oceans richer than we found them.
