This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gulkana River Arctic grayling Thymallus arcticus were radiotagged in July 2020 and tracked for the following 15 months to describe seasonal distributions, migration patterns, and to identify spawning areas. Radio tags were surgically implanted into 100 Arctic grayling ≥320 mm FL in the lower 6 river kilometers (RKM) of Hungry Hollow Creek, located in the Middle Fork Gulkana River drainage. A total of 8 aerial tracking surveys were flown from 29 September 2020 through 14 October 2021, and a fixed tracking station was installed below the confluence of Hungry Hollow Creek and the Middle Fork Gulkana River. Arctic grayling located during tracking surveys exhibited strong migratory patterns. The general seasonal movements of radiotagged fish were extensive, with all radiotagged fish leaving Hungry Hollow Creek in late summer or fall and migrating downstream for overwintering. All fish that survived the winter left Hungry Hollow Creek from 16 July–7 October 2020, and had a mean date of passage of 1 September. Radiotagged fish remained stationary for most of the winter before generally moving upstream in spring for spawning, then moving even further upstream for summering. Fish that survived a full year had a mean home range of 85.2 RKM and a maximum home range of 137.6 RKM. The radiotagged Arctic grayling in this study dispersed throughout the drainage for overwintering and spawning, representing most previously documented seasonal use areas and reinforcing the importance of this small reach of river to the population.

Available in PDF, EPUB and Kindle. Book excerpt: This study will describe the seasonal distribution of Arctic grayling Thymallus arcticus captured in Hungry Hollow Creek of the Middle Fork Gulkana River during summer. Arctic grayling will be captured using hook-and-line gear in mid-July. One hundred adult Arctic grayling ≥320 mm FL will be surgically implanted with radio tags that will operate for ~17 months. Radiotagged Arctic grayling will be tracked throughout the year to determine overall distribution, including overwintering, spawning, and summering areas, as well as migration timing among these locations. The seasonal proportion of the tagged fish residing in Hungry Hollow Creak and the mainstem of the Gulkana River will also be estimated.

This book was released on 2019 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gulkana River Arctic grayling Thymallus arcticus were radiotagged in fall 2016 and tracked for the following 14 months to describe seasonal distributions, migration patterns, and to identify spawning areas. Radio tags were surgically implanted into 126 Arctic grayling ≥320 mm fork length (FL) in a 64.5 river kilometer (rkm) reach of the Gulkana River mainstem from the confluence of the Middle Fork Gulkana River down to a point approximately 5 rkm above Sourdough Creek. A total of 15 aerial tracking surveys were flown from 7 November 2016 through 3 November 2017. Arctic grayling located during tracking surveys exhibited migratory behavior. Fish that survived a full year had a mean home range of 60.9 rkm and 8 fish had home ranges >100 rkm. Migrations for spawning were generally upstream and began in early May. Most fish made post spawning movements upriver to summering locations in June and July, then downstream migrations to overwintering areas starting in August. Several new spawning areas were documented with Stump Creek and the West Fork Gulkana River being the most significant. Radiotagged fish were also present in other smaller unnamed tributaries around the West Fork Gulkana River confluence during the spawning period. Already recognized spawning tributaries such as the Middle Fork Gulkana River, Twelvemile Creek, and Sourdough Creek had radiotagged Arctic grayling in them during the spawning period, but Poplar Grove did not.

This book was released on 2021 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 2-event mark–recapture study was conducted to estimate the abundance of Arctic grayling in a 9-river kilometer (RKM) reach of Lower Hungry Hollow Creek and Middle Fork Gulkana River in 2019. Intensive hook and line sampling occurred 18–22 July for the first event and 26–29 July for the second event. A total of 2,469 Arctic grayling ≥270 mm fork length (FL) were captured and marked during the first event and 2,270 were captured and examined during the second event, 204 of which were marked during the first event. A length-stratified Bailey estimator was used to estimate the abundance of Arctic grayling ≥270 mm FL in the 9-RKM study area and, because of uncertainty associated with movement at the lower end of this area, in a truncated portion of the study area encompassing only the lower 6-RKM of Hungry Hollow Creek. The estimated abundance of Arctic graying ≥270 mm FL was 40,952 (95% CI = 29,732–52,732) in the 9-RKM study area and 28,894 (95% CI = 17,975–39,813) in the 6-RKM area. Because precision requirements for these estimates were not met due to low capture probabilities for fish 270–289 mm FL, abundance was also more precisely estimated for Arctic grayling ≥290 mm FL. The estimated abundances of Arctic grayling ≥290 mm FL in the 9-RKM and 6-RKM study areas were 16,356 (95% CI = 14,050–18,663) and 10,416 (95% CI = 8,774–12,058) fish, respectively. Individual length strata abundance estimates are presented in this report. Length compositions for Arctic grayling ≥270 mm FL were very similar in both study areas, with fish 270–289 mm accounting for >60% of the estimated population, whereas larger fish (i.e., fish ≥320 mm FL) accounted for

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game investigated the summer residence and spring spawning areas of Arctic grayling Thymallus arcticus inhabiting the Five-Mile Clearwater Creek. To describe seasonal distributions and migrations, radio tags were surgically implanted into 73 Arctic grayling of adult size (297-410 mm FL) during Summer 2016, and locations were periodically determined through 8 aerial surveys occurring between July 2016 and October 2017. Additionally, residency time in the river was determined by detecting entry and exit timing of tagged fish at a tracking station at the mouth of the Five-Mile Clearwater Creek. Radiotagged Arctic grayling were found in 8 different spawning areas that were up to 225 river km apart from each other. Most tagged fish resided in the Five-Mile Clearwater Creek during summer for less than 75 days.

Download or read book Seasonal Distributions and Migrations of Arctic Grayling in the Goodpaster River written by Andrew D. Gryska and published by . This book was released on 2019 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game and the Sumitomo Metal Mining Pogo LLC cooperated on a radiotelemetry project that investigated the seasonal distributions and migrations of Arctic grayling Thymallus arcticus inhabiting the Middle and Upper Goodpaster River, relative to the Pogo Mine. Radio tags were surgically implanted into 178 Arctic grayling of adult size (281-460 mm fork length [FL]) during August 2014, and locations were periodically determined through 12 aerial surveys occurring between September 2014 and December 2015. Before winter arrived, Arctic grayling vacated all small tributaries and most fish (95%) overwintered throughout the mainstem Goodpaster River, while a few individuals resided in the Tanana River. The largest concentration of radiotagged fish (57%; SE = 4.3%) was located in the 32.5 km Upper Goodpaster River section, between Glacier Creek and the Eisenmenger Fork (), and the smallest concentration (8%; SE = 2.4%) was located adjacent to the mine in the Middle Goodpaster River section, between Glacier and Central creeks (32.5 km). The Lower Goodpaster River section, from Central Creek to the mouth (104 km), held 30% (SE = 4.0%) of fish during winter, half of which were in the lower 25 km. Most grayling spawned near their overwintering area. After spawning, the tagged fish quickly vacated the Lower Goodpaster River and dispersed throughout the Middle and Upper Goodpaster River mainstem and tributaries. Fidelity to their summer feeding areas was observed but varied among individuals, including one fish that left the Goodpaster River and migrated to the Delta Clearwater River. These results indicate that impacts to the Arctic grayling population by a disturbance are lessened because the population is widely distributed and has an ability to disperse and recolonize. Nonetheless, the water quality and quantity of the migration corridor are key to the resilience of the population. Finally, these seasonal locations and the timing to and from all seasonal habitats can be used to avoid or greatly reduce impacts due to ongoing and future development.

Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game and the U.S. Bureau of Land Management cooperated in a radiotelemetry project that investigated the seasonal distributions of Arctic grayling inhabiting a 17 km portion of the Delta River in the central Alaska Range that is designated as Wild and Scenic and is adjacent to potential mineral development. Radio tags were surgically implanted into 100 Arctic grayling of adult size during July 2008, and 12 surveys (aerial and boat) occurred through December 2009 to describe seasonal locations.
Download or read book More Readings From One Man s Wilderness written by John Branson and published by Skyhorse. This book was released on 2012-02-07 with total page 872 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout history, many people have escaped to nature either permanently or temporarily to rest and recharge. Richard L. Proenneke, a modern-day Henry David Thoreau, is no exception. Proenneke built a cabin in Twin Lakes, Alaska in 1968 and began thirty years of personal growth, which he spent growing more connected to the wilderness in which he lived. This guide through Proenneke’s memories follows the journey that began with One Man’s Wilderness, which contains some of Proenneke’s journals. It continues the story and reflections of this mountain man and his time in Alaska. The editor, John Branson, was a longtime friend of Proenneke’s and a park historian. He takes care that Proenneke’s journals from 1974-1980 are kept exactly as the author wrote them. Branson’s footnotes give a background and a new understanding to the reader without detracting from Proenneke’s style. Anyone with an interest in conservation and genuine wilderness narratives will surely enjoy and treasure this book.

Download or read book The Bureau Of Indian Affairs written by Theodore W Taylor and published by Routledge. This book was released on 2019-07-11 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landmark legislation, such as the Indian Self-Determination and Education Assistance Act of 1975, as well as increasing federal subsidies for Native Americans, growing demand for the energy resources located on the 50 million acres of Native American lands, expanding numbers of Native Americans and their interest groups, devastating reservation unemployment, and other factors have in the last decade radically changed the environment in which the Bureau of Indian Affairs (BIA) operates. This book presents an up-to-date description and analysis of the BIA, including its missions, organization, functions, administration, problems, and decision-making and -implementing processes. Attention is given, too, to the often friction-laden interactions of the BIA and other governmental units (among them the Department of the Interior, Office of Management and Budget, Congress, the courts, Indian Health Service, and tribal, state, and local governments) with each other and with Indian interests. Abundant tables provide information on such topics as the 1980 Indian population and land by state, BIA budgets, and agricultural and mineral production on Indian lands. Dr. Taylor examines the current operations of the Bureau under the Reagan administration and explores possible policy decisions that will affect Native Americans as well as non-Indian citizens. The book includes a foreword by Phillip Martin, chief of the Mississippi Band of Choctaw Indians and president of the National Tribal Chairmen's Association.
