Available in PDF, EPUB and Kindle. Book excerpt: In 1998, approximately 235 km of Harlequin Duck stream surveys were conducted on six streams, with the majority of effort focused on four Lower Clark Fork streams (Rock Creek, Swamp Creek, Marten Creek, Vermilion River). Additional streams surveyed were Trail Creek (North Fork Flathead River drainage) with one pair survey and one brood survey, and Upper McDonald Creek (Glacier National Park) with one brood survey. On the Lower Clark Fork streams, stream flow was significantly below normal during early-May pair surveys. A minimum of 24 adult Harlequins (13 males, 11 females) was seen on 3 streams. These included Marten Creek (7 pairs, 2 males), Rock Creek (1 pair, 1 male, 1female), Vermilion River (2 pairs) and Swamp Creek (no birds). The number of birds observed was about average for all streams, although Swamp Creek again had no birds. Brood surveys were conducted during July and early August 1998. Seven broods were observed on the Lower Clark Fork streams (2 each on Marten Creek and Vermilion River, 3 on Rock Creek), successfully producing a maximum 11 young on Marten Creek, 6 young on Vermilion River, and 13 young on Rock Creek. Age of broods indicated that nesting among these streams was initiated over a period of at least three or four weeks. New birds were banded on Marten Creek (2 males, 2 females, 5 juveniles), Vermilion River (1 female, 3 juveniles) and Rock Creek (2 juveniles). One third-year female, banded as a juvenile on Swamp Creek in August 1995, was observed paired in May 1998 on Rock Creek, an inter-stream movement of ca. 21 km, and the first documented between these two streams. Stream survey results from other areas were as follows. On Trail Creek (N. Fork Flathead drainage) 3 pairs and 1 male were counted on 14 May, 1 female (already banded) with a brood of 1 juvenile was captured and banded on 7 August. On McDonald Creek in Glacier National Park, park personnel reported a maximum of 8 pairs in spring. During brood surveys, 2 females (1 already banded) with 2 broods (8 juveniles) were captured and banded on 6 August. Three additional broods (3 females, 13 juveniles) were counted on 17 and 19 August by park personnel, and 2 female (1 already banded) and 12 juveniles were banded.

Available in PDF, EPUB and Kindle. Book excerpt: This edited book has been designed to serve as a natural resources engineering reference book as well as a supplemental textbook. This volume is part of the Handbook of Environmental Engineering series, an incredible collection of methodologies that study the effects of resources and wastes in their three basic forms: gas, solid, and liquid. It complements two other books in the series including "Natural Resources and Control Processes" and "Environmental and Natural Resources Engineering". Together they serve as a basis for advanced study or specialized investigation of the theory and analysis of various natural resources systems. The purpose of this book is to thoroughly prepare the reader for understanding the topics of global warming, climate change, glacier melting, salmon protection, village-driven latrines, engineers without borders (USA), surface water quality analysis, electrical and electronic wastes treatment, water quality control, tidal rivers and estuaries, geographic information systems, remote sensing applications, water losses investigations, wet infrastructure, lake restoration, acidic water control, biohydrogen production, mixed culture dark anaerobic fermentation, industrial waste recycle, agricultural waste recycle, recycled adsorbents, heavy metals removal, magnetic technology, recycled biohydrogen materials, lignocellulosic biomass, extremely halotolerant bacterial communities, salt pan and salt damaged soil. The chapters provide information on some of the most innovative and ground-breaking advances in resources conversation, protection, recycling, and reuse from a panel of esteemed experts.

Book excerpt: Drafting a Conservation Blueprint lays out for the first time in book form a step-by-step planning process for conserving the biological diversity of entire regions. In an engaging and accessible style, the author explains how to develop a regional conservation plan and offers experience-based guidance that brings together relevant information from the fields of ecology, conservation biology, planning, and policy. Individual chapters outline and discuss the main steps of the planning process, including: • an overview of the planning framework • selecting conservation targets and setting goals • assessing existing conservation areas and filling information gaps • assessing population viability and ecological integrity • selecting and designing a portfolio of conservation areas • assessing threats and setting priorities A concluding section offers advice on turning conservation plans into action, along with specific examples from around the world. The book brings together a wide range of information about conservation planning that is grounded in both a strong scientific foundation and in the realities of implementation.

Book excerpt: The Bowhead Whale: Balaena mysticetus: Biology and Human Interactions covers bowhead biology from their anatomy and behavior, to conservation, distribution, ecology and evolution. The book also discusses the biological and physical aspects of the Arctic ecosystem in which these whales live, with careful attention paid to the dramatic changes taking place. A special section of the book describes the interactions of humans with bowheads in past and present, focusing on their importance to Indigenous communities and the challenges regarding entanglement in fishing gear, industrial noise and ship strikes. This volume brings together the knowledge of bowheads in one place for easy reference for scientists that study the species, marine mammal biologists, but, equally important, for everyone who is interested in the Arctic. - Presents the only current book dedicated to this species - Includes short, high-impact chapters that make it possible to review all bowhead biology in one compact volume - Illustrated with never-before published photos of bowheads in their natural environment - Provides a platform for an in-depth understanding of indigenous whaling
