Download or read book Influence of Sympatric Lesser Snow Geese Chen Caerulescens Caerulescens on Reproductive Performance Behavior and Food Habits of Canada Geese Branta Canadensis Interior on Akimiski Island Nunavut written by Jeffrey Scott Gleason and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2003 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on Akimiski Island, Nunavut, indicates declining numbers of nesting Southern James Bay Population (SJBP) Canada Geese (Branta canadensis interior) while increases have been documented for number of breeding Lesser Snow Geese (Chen caerulescens caerulescens). Low direct recovery rates of goslings is suggestive of late-summer mortality which may be limiting recruitment for Canada geese on Akimiski Island. This study was designed specifically to (1) compare Canada Goose reproductive performance, incubation and brood-rearing behavior in areas of allopatry and sympatry and with Lesser Snow Geese, (2) determine if there are differences in diets of Canada Geese in areas of allopatry and sympatry, and (3) determine if there are differences in diets of Canada and Lesser Snow Geese in the area of sympatry. I documented annual variation for all and spatial variation for some reproductive parameters measured. Results of between-area comparisons of reproductive performance tended to suggest that in some years, Canada Geese nesting in the area of sympatry contribute little towards the maintenance of the island segment of this population. During incubation when females were on nests, male behavior varied as a function of year, area, time-of-day, and incubation stage. Overall, male Canada Geese allocated their time primarily to vigilance, feeding, and resting when females were on the nest. Males in the area of allopatry were more vigilant and fed less compared to males in the area of sympatry. When females were on the nest, their behavior varied relative to time-of-day, incubation stage, and temperature. Females in the area of allopatry were more vigilant than females in the area of sympatry, but overall, females on the nest allocated their time primarily to resting and maintenance. Recess behavior of Canada Geese varied relative to sex, incubation stage, and temperature, but not area, though pairs in the area of allopatry tended to spend more time alert and less time feeding compared to pairs in the area of sympatry. During recesses, males allocated their time primarily to vigilance, whereas females allocated nearly equal proportions of time to feeding and maintenance. Overall, brood-rearing behavior varied relative to year, area, time-of-day, sex/age class, days since peak hatch, brood size, brood density, and temperature. Overall, results are indicative of exploitation competition and I suggest that present foraging conditions are insufficient to meet the energetic demands of breeding Canada Geese, as well as breeding and staging Lesser Snow Geese, molt-migrant Giant Canada Geese, and staging Atlantic Brant. Such an energy deficit is particularly detrimental to the growth and development of Canada Goose goslings resulting in locally poor recruitment which presumably will lead to a much depressed breeding population of Canada Geese on Akimiski Island.

Download or read book Wetland Carbon and Environmental Management written by Ken W. Krauss and published by John Wiley & Sons. This book was released on 2021-11-23 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Download or read book The Private Eye written by Mary Burns and published by UBC Press. This book was released on 1996 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Private Eye we learn about snow geese through the eyes of Native people, scientists, artists, hunters, and farmers. Yup'ik Eskimo Charles Hunt harvests snow geese along the Yukon River delta each fall, continuing a subsistence way of life that has existed for millennia. Russian, Canadian, and US scientists track the movements of the geese each spring and fall, banding, sexing, counting, and precisely monitoring the activities of these beautiful birds. Robert Bateman provides an artist's view of nature and relates how his curiosity led him to join a camp set up at a remote nesting site. Mary Burns also talks to hunters, joining a party of them as they wait for their snow geese decoys to lure the real thing into a Westham Island field in the Fraser delta. To complete the experience she prepares snow geese for supper. As well, Burns travels around the Skagit River delta during a population survey and meets a dairy farmer who describes both the wild flocks that converge on his fields each spring and the snow geese he raises in pens. The Private Eye suggests that by acknowledging our many and varied connections with the natural world, we will have a better understanding of the human place in it.

Download or read book Song of the North Wind written by Paul A. Johnsgard and published by U of Nebraska Press. This book was released on 1979-01-01 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries the snow goose has signified the passing seasons to the Indians?its white feathers a symbol of the breadth of life and a reminder of the roles the birds played as messengers between heaven and earth. The importance of the geese in these roles is attested by their prominence in Indian lore and myth. ø As a boy growing up in North Dakota, Paul A. Johnsgard measured his winters not by conventional time units, but in the days it took for the snow geese to return from their wintering grounds to Lake Traverse. In this book he recounts the story of one year in the life of a pair of snow geese-the incubation and breeding of the young in the Arctic, their hazardous migration to winter quarters near the Gulf of Mexico, and the spring migration back to the Arctic.
