This book was released on 2006 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waterfowl are renowned for their ability to exploit a wide variety of food resources. They feed on fresh and marine water invertebrates, aquatic and terrestrial plants, and agricultural grains and crops. This nutritional flexibility has allowed them to exploit virtually every water environment and establish a world-wide distribution. Their nutritional flexibility can be attributed to the diversity of anatomical, behavioral, and physiological adaptations that exist within Anatidae. Of particular importance is the ability of intestinal organs to adjust to a changing diet. The intent of this research was to investigate the role of the Canada goose (Branta candensis maxima) cecum in facilitating nutritional flexibility. True metabolizable energy assays indicated that the cecum increases the ability of the digestive system to extract energy from nutritionally poor foods (i.e. high fiber foods). Carboxymethyl cellulose assays conducted on cecal contents, confirmed the presence of cellulose-splitting bacteria within the ceca. True amino acid digestibility assays failed to detect differences in amino acid digestibility between intact and cecectomized geese. The bioassay, however, might not have been the appropriate approach to use with Canada geese. With the exception of a decrease in pancreas weight, the removal of the cecum did not lead to compensatory growth in the remaining digestive organs. Post-mortem examination, however, led to the discovery that 8 out of the 9 cecectomized geese had one or both ceca in various stages of regeneration. From an evolutionary perspective, our results indicate that the ability of the cecum to extract additional nutrients from low quality foods could make a difference in survival during periods of food shortages or food unavailability.

Download or read book Comparing Migration Ecology Among Geographically Distinct Populations of Canada Geese Branta Canadensis and Cackling Geese Branta Hutchinsii written by Leanne Neufeld and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Migration timing is important to the reproductive success of birds, as mismatches with peak food abundance can lead to reduced fitness and population declines. Birds breeding at northern latitudes may be more susceptible to the effects of climate change, as narrower seasonality farther north can result in timing mismatches for birds that may rely more on endogenous cues to migrate. Few studies have used direct-tracking methods on waterfowl to compare differences in migration ecology across a latitudinal gradient. Spatiotemporal tracking data can also be useful for conservation and management of waterfowl. Giant Canada Geese (Branta canadensis maxima) are increasing in numbers, to the point where they are declared overabundant. Special hunting seasons may be opened to increase harvest of this subspecies, but care must be taken to avoid non-target goose populations. My first objective was to use direct-tracking data to examine differences in migration timing and rate between three goose populations: giant Canada Geese, Southern Hudson Bay Canada Geese (B. c. interior), and Cackling Geese breeding across a broad latitudinal range (49-65 degrees). My second objective was to apply my findings in relation to conserving and managing overabundant Canada Geese, and whether spring migration in overabundant Giant Canada Geese and less abundant Cackling Geese overlap with the proposed spring hunting season (March 1 to March 31). I found that southern-breeding geese migrated earlier and with more variation in spring compared to more northern-breeding geese, and in fall the northern-breeding geese migrated earlier compared to more southern-breeding geese. I also found that all three goose populations were in Manitoba during the fall hunting season, and about 9% of Giant Canada Geese were in Manitoba during the proposed spring hunting season. Increasing our knowledge of migration ecology in waterfowl can be useful in conservation of species that may be susceptible to the effects of climate change, or managing species that are increasing in numbers in which timing data can aid decisions to open special hunting seasons to increase harvest rates.

Download or read book Managing Canada Geese in Urban Environments written by Arthur E. Smith and published by . This book was released on 1999 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you're a parks manager, waterfront property owner or golf-course superintendent, you may be dealing with one of the drawbacks of the Canada goose success story - resident, nonmigratory geese. As Canada goose numbers have soared in recent years, so have complaints about urban goose problems - primarily goose droppings, overgrazing and trampling of vegetation, and aggressive behavior toward humans. Managing Canada Geese in Urban Environments is a 42-page guide to legal, effective ways of persuading problem geese to go elsewhere. The guide includes an overview of goose biology and behavior, but most of the text is devoted to management and control techniques, arranged by their physical impact on the geese. The techniques range from basic (quit feeding the birds) to extensive - habitat modification, hazing and scaring techniques, chemical repellents, control of reproduction, and removal. For example, the habitat section reviews fences and overhead wires and grids, plant and rock barriers, and modification of vegetation, shorelines, islands and ponds. The hazing discussion covers noisemakers such as fireworks and propane cannons, goose scarecrows and other visual scare techniques, and dogs trained to patrol for geese. Tables provide a quick summary of timing, cost, necessary permits, strengths and weaknesses of each technique. The guide also discusses the human and political dimensions of urban goose management, and how to develop an integrated management strategy. It lists on-line information sources, as well as contact information for equipment suppliers and wildlife control agencies. "Urban Canada goose populations have increased dramatically in both numbers and distribution over the past 10 to 15 years. Almost any body of water, especially in southeast Wisconsin, can expect geese, if they aren't there already, " says co-author Scott Craven, extension wildlife ecologist at UW-Madison's College of Agricultural and Life Sciences. "Small numbers of geese are attractive and highly desirable, but it's very easy to quickly experience too much of a good thing. Information on living with geese has not been readily available, and some 'solutions' may have little chance of actual success. The guide provides would-be goose managers with the information they need to address a very complex urban wildlife problem." (http://www.cals.wisc.edu/media/news/02_99/goose_doo.html).
Download or read book The Social Life of Greylag Geese written by Isabella B. R. Scheiber and published by Cambridge University Press. This book was released on 2013-08-29 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flock of greylag geese established by Konrad Lorenz in Austria in 1973 has become an influential model animal system and one of the few worldwide with complete life-history data spanning several decades. Based on the unique records of nearly 1000 free-living greylag geese, this is a synthesis of more than twenty years of behavioural research. It provides a comprehensive overview of a complex bird society, placing it in an evolutionary framework and drawing on a range of approaches, including behavioural (personality, aggression, pair bonding and clan formation), physiological, cognitive and genetic. With contributions from leading researchers, the chapters provide valuable insight into historic and recent research on the social behaviour of geese. All aspects of goose and bird sociality are discussed in the context of parallels with mammalian social organisation, making this a fascinating resource for anyone interested in integrative approaches to vertebrate social systems.
