This book was released on 2010 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural reproduction of Chinook salmon now supplies half of all recruits to the Lake Michigan sport fishery but may vary greatly due to environmental variability and biotic interactions in tributary nursery areas. From 2004 to 2007, I evaluated the relative effect of predation by stocked sport fish species on Chinook salmon recruitment variability in the Muskegon River, a large Lake Michigan tributary. Together, walleye and brown trout annually consumed from 17 to 47% of available Chinook salmon parr. Although brown trout consumed large quantities of Chinook parr, I found that hatchery trout dominated walleye diets. Walleye were size-selective for small hatchery trout but prey size was independent of predator size. In general, walleye showed neutral selection for prey species although they positively selected for rainbow trout and selected against Chinook parr in some years. Brown trout consumed smaller-than-average Chinook salmon parr although prey size was also independent of predator size. Chinook parr were positively selected as prey by brown trout but only in April when parr were

Download or read book Natural Reproduction and Recruitment of Chinook Salmon in the Salmon River New York An Application of Otolith Microstructure Analysis written by Nathan Gail Smith and published by . This book was released on 2005 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stocking of hatchery-reared Chinook salmon (Oncorhynchus tshawytscha) in Lake Ontario has led to the development of a sport fishery that provides high economic returns to local communities. Changes in habitat quality, including changes in flow associated with Federal Energy Regulatory Commission reauthorization protocols since the mid 1990s in the Salmon River, NY, may have led to increased natural reproduction in this river. Increases in natural production of Chinook in Lake Ontario could lead to changing management practices in the fishery. In order to measure wild reproduction I used known origin young-of-the-year (YOY) Chinook salmon from hatchery and wild sources as a baseline for separating these groups using otolith microstructure. Measuring 20 days growth from 300 mum inward toward the origin correctly classified 100% of known hatchery fish, and 89% of known wild fish. These measurements were used to determine the origin of Chinook salmon smolts caught in the nearshore of Lake Ontario adjacent to the Salmon River, NY in 2000 (85%) and 2001 (89%). I also evaluated the potential for carbon and oxygen stable isotopes in otoliths for differentiation of hatchery and wild YOY Chinook. Stable isotope methods show promise in separating hatchery and wild fish based on known-origin otoliths from 1999 and 2001, but further research is required before large scale application in Lake Ontario. In addition to sampling outmigrating smolts, I applied the 300 mum method to a sample of adults returning to the Salmon River from 2000-2002. Wild origin fish contributed between 10 and 25% of the returning adults for the 6 year classes 1995-2000. There was no time trend in the proportion of wild fish and therefore no evidence for an increase in natural production due to water flow changes in the Salmon River during the late 1990s. Because of the life history of Chinook salmon and time limitations of the study, I was unable to directly compare estimates of smolts from 2000-2001 with returning adults from those year classes, however my results for both YOY and adult Chinook indicate that natural reproduction may play a larger role in Lake Ontario than previously thought.

Available in PDF, EPUB and Kindle. Book excerpt: This resource book provides information and activity sheets on explorers of North America. The five sections of the book trace the explorers' contributions both geographically and chronologically. Each section includes thought questions, biographical portraits and skill activities for grades 4-8. Section 1, "They Opened the Door," profiles Leif Erikson, Christopher Columbus, John Cabot, Juan Ponce de Leon, Hernando Cortez, Giovanni da Verrazano, and Hernando de Soto. "They Navigated Great Lakes and Rivers" examines the contributions of Jacques Cartier, Samuel de Champlain, Henry Hudson, Robert de La Salle, and Jean Baptiste Le Moyne, Sieur de Bienville. "They Crossed Vast Plains and Deserts" focuses on Estevanico, Francisco Vasquez de Coronado, Daniel Boone, George Rogers Clark, and Jean Baptiste Point du Sable. "They Blazed Western Trails" highlights the work of Sir Francis Drake, Meriwether Lewis and William Clark, Sacagawea, George Washington Bush, John Charles Fremont and Kit Carson, James Beckwourth, and Isabella Bird Bishop. "They Aim for New Frontiers" chronicles the work of Robert E. Peary and Matthew Henson, Louise Arner Boyd, Robert Ballard, Sylvia Alice Earle, Neil Armstrong, Sally Kristen Ride, and Franklin Chang-Diaz. A time line of the explorers, maps of North America, and answers to the activity sheets are provided. (EH)

Book excerpt: This eclectic and carefully organized range of essays-from women's history and settler societies to colonialism and borderlands studies-is the first collection of comparative and transnational work on women in the Canadian and U.S. Wests. It explores, expands, and advances the aspects of women's history that cross national borders. Out of the talks presented at the 2002 "Unsettled Pasts: Reconceiving the West through Women's History," Elizabeth Jameson and Sheila McManus have edited a foundational text for pioneering scholars of this emergent, interdisciplinary field. "We are stepping into unfamiliar territory." This unfamiliar territory is the borderlands of women’s histories traversing the American and Canadian Wests. Specialists in women’s history, settler societies, colonialism, storytelling, education, and native and borderlands studies introduced by Elizabeth Jameson and Sheila McManus pool their distinct contributions toward forging the very first comparative, transnational collection of its kind. "We cannot build bridges across unmapped divides." Sixteen essays arising from the "Unsettled Pasts: Reconceiving the West through Women’s History" conference at the University of Calgary comprise this foundational text. One Step Over the Line is not only the map; it is the bridgework to span the transnational, gendered divide—a must for readers who have been searching for a wide, inclusive perspective on our western past.
