This book was released on 1982 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mail questionnaire survey of waterfowl hunters is conducted each year in the United States to provide information on waterfowl kill and hunter activity.

Book excerpt: Nonconsumptive outdoor recreation has increased greatly in recent years, and there is growing concern about the effects of such activities on wildlife and wildlife habitats. Unfortunately, information concerning these effects is scare and widely scattered. To stimulate research and assist resource planners and managers in utilizing available information, an annotated bibliography of human-wildlife interactions is provided. The report reviews interactions between wildlife and humans participating in nonconsumptive outdoor recreation activities. Also provided are indexes to authors, species, keywords and geographic regions; an annotated list of keywords; and a list of bibliographies on related topics.

Available in PDF, EPUB and Kindle. Book excerpt: Most mourning doves (Zenaida macroura) banded in eastern Missouri in 1968-76 and recovered outside the State moved south-southeast into Kentucky, Tennessee, Mississippi, Alabama, Georgia, Florida, and South Carolina. Most doves banded in central and western Missouri and recovered elsewhere moved south-southwest into Kansas, Oklahoma, Louisiana, Texas, Mexico, and Central America. Several central Missouri doves moved southeast.

This book was released on 1982 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A banding program for mourning doves (Zenaida macroura) was conducted by the 14 Central Management Unit (CMU) States and the U.S. FIsh and Wildlife Service during 1967-74. Banding and recovery records, as well as data from annual call-count and harvest surveys, were subsequently analyzed by a subcommittee of the Central Migratory Shore and Upland Game Bird Technical Committee. This paper presents information on mourning dove habitat, hunting regulations, and harvest in the CMU; distribution and derviation of band recoveries in and from CMU; distribution of mourning dove harvest in Mexico and Central America; chronology of migration; survival and recovery rates; effects of hunting on CMU mourning dove populations; and indirect nationwide mourning dove population estimates.

Download or read book Technique for Structuring Wildlife Guilds to Evaluate Impacts on Wildlife Communities written by Henry L. Short and published by . This book was released on 1982 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a technique for ordering wildlife information according to physical strata and vegetative structure so that a variety of statistical analyses can be accomplished. Individual wildlife species are assigned to cells in a species-habitat matrix on the basis of feeding and breeding activities within physical strata in representative types of vegetative cover: the cells within the species-habitat matrix are assigned numeric values. The statistical analyses are thus based on the areas that individual species occupy within the species-habitat matrix. Computer graphics are used to represent the structure of wildlife communities and cluster analysis routines are used to describe the potential wildlife guilds that may exist in different vegetative communities. Different numbers of wildlife guilds will occur in species and presumably also of wildlife guilds present within a type of cover is modified by physical attributes of the vegetation within that cover type. The products of this analytical technique may be suitable for evaluating habitat quality, impact assessments, regional inventories and assessments of wildlife resources, and land-use planning activities.

Download or read book Organochlorine Residues in Eggs of Alaskan Seabirds written by and published by . This book was released on 1982 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: One egg from each of 440 clutches of eggs of 19 species of Alaskan seabirds collected in 1973-76 was analyzed for organochlorine residues. Both frequency of occurrence and concentration of residues in the eggs differed geographically and by species, apparently reflecting non-uniform distribution of organochlorines in the environment, dissimilar feeding habits and migration patterns of the species, or metabolic differences among the species.

Download or read book Changes in Vegetation Structure in Seeded Nesting Cover in the Prairie Pothole Region written by Kenneth F. Higgins and published by . This book was released on 1982 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A spample of 365 stands of seeded nesting cover (mixtures of cool-season grasses and legumes) was studied in the glaciated prairie pothole region during 1977-79. Measurements of species composition, canopy cover, plant height, and visual obstruction values differed with stand age but only in a general way when results from over the entire region were pooled. Maximum values for plant height and visual obstruction occurred once per stand during the first 10 growing seasons. Although the year of maximum growth was variable and unpredictable, stands showed trends of degeneration in height and visual obstruction after the year of maximum growth.

Download or read book Bibliography of References to Avian Botulism written by Sonoma S. Wilson and published by . This book was released on 1982 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bibliography, first compiled in 1970 and published in response to many requests for information on avian botulism, has been updated to include the literature published through 1980. In general only, articles dealing primarily with the avian disease are included, as opposed to those concerned with the various aspects of the biology of Clostridium botulinum, either type C or type E.A few exceptions, such as Bengtson's report of the first isolation and description of the type C organism, are included for their historical interest. Progress reports and other administrative documents not available for distribution on request are excluded, as are textbook accounts, which are generally summaries of work published elsewhere. This bibliography was a cooperative effort by the National Wildlife Laboratory, U.S. Fish and Wildlife Service, and the U.S. National Park Service, which provided partial funding for the work. Although there was an attempt to list every important reference, no claim to complete coverage of the published literature is made and the authors will be grateful to users of the bibliography who call attention to errors or omissions.
