Available in PDF, EPUB and Kindle. Book excerpt: The rich tapestry of Alaska is threaded together by 365,000 miles of waterways, from cascading mountain streams to meandering valley rivers, from the meltwaters of glaciers to broad rivers that empty into the sea. This guide profiles a wide variety of rivers from all over Alaska, concentrating on trips for intermediate boaters, and including a few major expeditions for the experienced river-runner. A section on gear outlines what to take into the backcountry.

Download or read book Alaska Freshwater Policy Development written by Jedediah R. Smith and published by . This book was released on 2009 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Watershed partnerships are institutional entities defined by bioregional boundaries. They offer an opportunity to identify regionally specific freshwater needs and concerns, and provide information critical to resource agency decision-making. Changes to the freshwater system are inextricably linked to changes in the human system such as water consumption for household and industrial use, as well as through indirect drivers such as climate change. Alaska's position in the arctic and subarctic, where these changes are magnified and often poorly understood, creates a significant challenge to developing and adopting policies that are flexible enough to accommodate changes in the arctic ecosystem, and rigorous enough to avoid freshwater allocation conflicts experienced elsewhere in the world. Watershed partnerships provide a critical link between understanding changes at the local and regional scale and developing new policies able to adapt to future changes and demands for freshwater"--Leaf iii.

Download or read book Freshwater Fish Biogeography in the Bering Glacier Region Alaska written by Heidi L. Weigner and published by . This book was released on 2012 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bering Glacier, Alaska, is Earth's largest surging glacier, with surges occurring approximately every 20-30 years since 1900. Surges and subsequent retreats lead to a dynamic environment for aquatic communities, as glacial ice over-rides landscapes and new habitats form during glacial retreat. Lands around Bering Glacier are administered by the State of Alaska and the U.S. Bureau of Land Management (BLM). Purposes of this study are to characterize fish communities and provide information relevant to their management for BLM. Given Bering Glacier's remoteness, little information exists regarding its fish communities. Fish were collected over five summer field seasons (2002-2006), with 10 fish species collected in 80 lakes and streams. Results indicate that Dolly Varden (Salvelinus malma), threespine stickleback (Gasterosteus aculeatus), prickly sculpin (Cottus asper), and coho salmon (Oncorhynchus kislitch) are first to colonize new habitat after glacial retreat. Ten locations with sympatric populations of anadromous and resident freshwater threespine stickleback were found. Geometric morphometrics and genetic analyses were conducted on these species pairs to test hypotheses regarding their formation. Possible origins include sympatric speciation, double invasion of anadromous fish, and independent colonization by resident freshwater fish from pre-existing lakes and streams along with anadromous fish. Body shape analyses of anadromous vs. resident freshwater stickleback supported the independent colonization hypothesis, because of a lack of body shape co-variation between groups, a lack of correlation of geometric morphometric variables with site age, and few fish with intermediate body shape at each site. Origin hypotheses were tested by use of the frequency of the Euro-North American Clade (ENAC) vs. the Trans North Pacific Clade (TNPC) in the mtDNA as well as sequence divergence of a portion of the mtDNA gene NADH2. A greater proportion of TN PC fish exist in resident freshwater populations at all sites, supporting the independent colonization hypothesis. The NADH2 sequence data did not help to clarify the origins. Future research at Bering Glacier should examine broader scale sequence divergence in genomes of stickleback and other colonizing fishes to advance the understanding of contemporary evolution and management implications in this newly formed aquatic landscape.

Download or read book The Bears of Brooks Falls Wildlife and Survival on Alaska s Brooks River written by Michael Fitz and published by The Countryman Press. This book was released on 2021-03-09 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: A natural history and celebration of the famous bears and salmon of Brooks River. On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America’s greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them (with as many as forty-three bears sighted in a single day), and thousands of people come to watch in person or on the National Park Service’s popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous in three parts. The first forms an ecological history of the region, from its dormancy 30,000 years ago to the volcanic events that transformed it into the Valley of Ten Thousand Smokes. The central and longest section is a deep dive into the lives of the wildlife along the Brooks River, especially the bears and salmon. Readers will learn about the bears’ winter hibernation, mating season, hunting rituals, migration patterns, and their relationship with Alaska’s changing environment. Finally, the book explores the human impact, both positive and negative, on this special region and its wild population.
