This book was released on 2001 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Populations of Giant Canada Geese (Branta canadensis maxima) have increased dramatically throughout most of the Mississippi Flyway. This population expansion has been accompanied by an increase in goose-related problems, including depredation of agricultural crops, airport hazards, fecal contamination of water used for drinking or swimming, and damage to lawns, parks, beaches, and golf courses, caused by overgrazing, trampling, feathers, and defecation. Failure to control giant Canada goose populations through traditional harvest methods such as hunting, has prompted interest in alternative harvest methods (nest manipulations, welfare harvest, and nesting female harvest) as a means of reducing goose numbers. The intent of this research was to generate long-term reproductive, survival and bioenergetics data and to utilize these data to develop a population model specific to Missouri Giant Canada Geese. The model was then used to identify population parameters that most influence population growth and to evaluate proposed management actions. Sensitivity analyses indicated that the effect of adult survival on population growth was much greater than any other population parameter. Alternative harvest simulations indicated that nesting female harvest was the most effective means of reducing populations to statewide management objectives. From a management perspective, our results indicate that efforts to control numbers of giant Canada geese should focus on reducing adult survival, in particular adult female survival. It is unlikely that the required reduction in adult survival necessary to reach management objectives will be achieved through traditional harvest methods. Therefore, a combination of non-hunting lethal alternatives will be required.

Book excerpt: AWARDS:2006 Outstanding Academic Title, by CHOICEThe 2005 Award for Excellence in Professional and Scholarly Publishing by the Association of American Publishers (AAP) Best Reference 2005, by the Library JournalRivers of North America is an important reference for scientists, ecologists, and students studying rivers and their ecosystems. It brings together information from several regional specialists on the major river basins of North America, presented in a large-format, full-color book. The introduction covers general aspects of geology, hydrology, ecology and human impacts on rivers. This is followed by 22 chapters on the major river basins. Each chapter begins with a full-page color photograph and includes several additional photographs within the text. These chapters feature three to five rivers of the basin/region, and cover several other rivers with one-page summaries. Rivers selected for coverage include the largest, the most natural, and the most affected by human impact. This one-of-a-kind resource is professionally illustrated with maps and color photographs of the key river basins. Readers can compare one river system to another in terms of its physiography, hydrology, ecology, biodiversity, and human impacts.* Extensive treatment provides a single source of information for North America's major rivers* Regional specialists provide authoritative information on more than 200 rivers* Full-color photographs and topographical maps demonstrate the beauty, major features, and uniqueness of each river system* One-page summaries help readers quickly find key statistics and make comparisons among rivers

Download or read book The Nature of Nebraska written by Paul A. Johnsgard and published by U of Nebraska Press. This book was released on 2005-01-01 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where the eastern and western currents of American life merge as smoothly as one river flows into another is a place called Nebraska. There we find the Platte, a river that gave sustenance to the countless migrants who once trudged westward along the Mormon and Oregon trails. We find the Sandhills, a vast region of sandy grassland that represents the largest area of dunes and the grandest and least disturbed region of mixed-grass prairies in all the Western Hemisphere. And, below it all, we find the Ogallala aquifer, the largest potential source of unpolluted water anywhere. ø These ecological treasures are all part of the nature of Nebraska. With characteristic clarity, energy, and charm, Paul A. Johnsgard guides us through Nebraska?s incredible biodiversity, introducing us to each ecosystem and the flora and fauna it sustains and inviting us to contemplate the purpose and secrets of the natural world as we consider our own roles and responsibilities in our connection with it.
