Book Synopsis Alaska Freshwater Policy Development by : Jedediah R. Smith
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.
Book Synopsis Freshwater Fish Biogeography in the Bering Glacier Region, Alaska by : Heidi L. Weigner
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.
Book Synopsis Riparian Areas by : National Research Council
Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Synopsis The Bears of Brooks Falls: Wildlife and Survival on Alaska's Brooks River by : Michael Fitz
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.

Book Synopsis Alaska's Changing Boreal Forest by : F. Stuart Chapin
Download or read book Alaska's Changing Boreal Forest written by F. Stuart Chapin and published by Oxford University Press. This book was released on 2006-01-12 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The boreal forest is the northern-most woodland biome, whose natural history is rooted in the influence of low temperature and high-latitude. Alaska's boreal forest is now warming as rapidly as the rest of Earth, providing an unprecedented look at how this cold-adapted, fire-prone forest adjusts to change. This volume synthesizes current understanding of the ecology of Alaska's boreal forests and describes their unique features in the context of circumpolar and global patterns. It tells how fire and climate contributed to the biome's current dynamics. As climate warms and permafrost (permanently frozen ground) thaws, the boreal forest may be on the cusp of a major change in state. The editors have gathered a remarkable set of contributors to discuss this swift environmental and biotic transformation. Their chapters cover the properties of the forest, the changes it is undergoing, and the challenges these alterations present to boreal forest managers. In the first section, the reader can absorb the geographic and historical context for understanding the boreal forest. The book then delves into the dynamics of plant and animal communities inhabiting this forest, and the biogeochemical processes that link these organisms. In the last section the authors explore landscape phenomena that operate at larger temporal and spatial scales and integrates the processes described in earlier sections. Much of the research on which this book is based results from the Bonanza Creek Long-Term Ecological Research Program. Here is a synthesis of the substantial literature on Alaska's boreal forest that should be accessible to professional ecologists, students, and the interested public.
