U.S. Declares War On Coyotes
Close Up Reports
The coyote has long been perceived as a threat by ranchers who graze their sheep on U.S. public lands. At the ranchers' insistence, U.S. government employees are paid to shoot coyotes from helicopters and airplanes, ambush them in cruel steel-jaw leghold traps, and plant cyanide guns that explode in the coyotes' faces. The Humane Society of the United States is irrevocably opposed to the unabated, cruel, and unnecessary practice of killing animals in the name of "predator control." The resumed use of denning and the threat of reinstituting 1080 makes our--and your--actions even more urgent.
Morphometric And Geographic Relationships Of Short-Tailed Shrews (Genus Blarina) In Kansas, Iowa, And Missouri, Nancy D. Moncrief, Jerry R. Choate, Hugh H. Genoways
Morphometric And Geographic Relationships Of Short-Tailed Shrews (Genus Blarina) In Kansas, Iowa, And Missouri, Nancy D. Moncrief, Jerry R. Choate, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Shrews of the genus Blarina from Iowa, Kansas, and Missouri were studied morphometrically and karyologically. The ranges of two species, B. brevicauda and B. hylophaga, overlap in a broad zone across southern Iowa and northern Missouri. Morphometric analyses revealed an unexpectedly large amount of cranial variation in B. brevicauda, and confirmed the presence of that species in the Kansas River Valley of northeastern Kansas. Considerable mensural overlap was found in geographic areas in which B. hylophaga and B. brevicauda are sympatric, evincing the need for further karyotypic and morphometric studies in those areas. No formal taxonomic changes are …
Plant Spacing: A Size Sensitive Model With Implications For Competition, Robert L. Bayn Jr.
Plant Spacing: A Size Sensitive Model With Implications For Competition, Robert L. Bayn Jr.
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
An algorithm is presented which partitions space among mapped plants according to their relative sizes and positions using one of eight rules for locating boundaries between individuals. The performance of those rules is examined using several natural and artificial data sets with diverse measures of individual size. The relative performance of the rules was the same for all natural data sets examined. The best rule, as measured by a high correlation between individual size and assigned space, placed the boundary at a distance between neighbors proportional to the relative sizes of neighbors as long as a maximum distance (also a …

The Suriname Small Mammal Survey: A Case Study Of The Cooperation Between Research And National Conservation Needs, Hugh H. Genoways, Henry A. Reichart, Stephen L. Williams
University of Nebraska State Museum: Mammalogy Papers
A cooperative program between the Foundation for Nature Preservation in Suriname and the Carnegie Museum of Natural History to survey the small mammals of Suriname is reviewed. The program has proven to be mutually beneficial and it is presented as a model for development of similar programs in the future. The technical assistance requested by the Foundation for Nature Preservation in Suriname concerned the distribution and natural history of small mammals, especially those occurring in the Nature Parks and Reserves. The Government of Suriname has established an excellent system of Reserves and Parks throughout the country. They are trying to …
The Economics Of Farm Animal Welfare, A. J. K. Webster
The Economics Of Farm Animal Welfare, A. J. K. Webster
International Journal for the Study of Animal Problems
The number of ways one can be nice or nasty to animals is legion. This article will consider only one very specific aspect of farm animal welfare, namely, those systems of intensive animal production in which the system itself, irrespective of the quality of the stockmanship within the system appears to restrict the normal behavior of farm animals to an unacceptable degree. The systems that were considered by the House of Commons Select Committee on Agriculture (1981) include egg production from hens in battery cages, production of veal from calves deprived of solid food and isolated in wooden crates, and …
Experiences In The Protection Of The Large Predators In Finland, Erkki Pulliainen
Experiences In The Protection Of The Large Predators In Finland, Erkki Pulliainen
Ecology Collection
During the nineteenth century, the large predators of Finland- wolf, bear, lynx, and wolverine- were exterminated in the southern and western regions of the country. There were almost no lynx by the late 1950s, but a protection order issued in 1968 has resulted in a steady increase in their number, to about 300 by 1980. There was a breeding population of wolverines until the late 1960s, but in the 1970s, most were killed by snowmobiles, and only 10-30 are now thought to inhabit the frontiers between Finland and the USSR, and Finland and Norway. Bears, in the 1970s, tended to …
Striving For Common Ground: Humane And Scientific Considerations In Contemporary Wildlife Management, Stephen R. Kellert
Striving For Common Ground: Humane And Scientific Considerations In Contemporary Wildlife Management, Stephen R. Kellert
Nature Collection
Although there is a diversity of opinion about how to view the relationship between humans and wildlife, recent political pressures from the current administration make it mandatory that these diverse groups coalesce to use their combined leverage to halt the planned incursions into the remaining habitats of wildlife. It is also important to begin to see nature as a complex and interrelated whole, and to respect the integrity of that whole, rather than simply select individual species for affection and protection.
Bureaucracy And Wildlife: A Historical Overview, Edward E. Langenau
Bureaucracy And Wildlife: A Historical Overview, Edward E. Langenau
Laws and Legislation Collection
This paper provides a framework for understanding the Government's position on many wildlife topics, including humane ethics. The historical role of Government in wildlife conservation is traced in relation to pertinent theories of bureaucracy. It is shown that Government involvement in wildlife conservation increased through successive stages of change because of interest group activity.
These periods of increased Government involvement in wildlife matters are shown to have followed periods of resource exploitation. Recurrent cycles of exploitation, accompanied by economic prosperity, have then been followed by attitudes favorable to conservation and political activism. This, in turn, has produced periods of backlash …
Urban Wildlife Habitat -- Present And Future, David Tylka
Urban Wildlife Habitat -- Present And Future, David Tylka
Ecology Collection
Many kinds of wild animals can become adapted to living in cities, provided that the right kinds of habitats are available and that their presence is accepted by city-dwellers. Suitable habitats can be furnished by traditional parks, tracts of "wild acres" set aside by cities, linear parks, cemeteries and golf courses, and transportation corridors. Buildings, rooftops, and institutional grounds can also provide habitat for animals like birds and butterfiles. Suburban areas can encourage the growth of local wildlife by neglecting to mow common grounds, or allowing sections of individual lawns to grow up with wild vegetation.
Ethical Issues And Future Directions In Wildlife Management, John W. Grandy
Ethical Issues And Future Directions In Wildlife Management, John W. Grandy
Nature Collection
Recent progress in protection of wildlife and wildlife refuges is currently being undermined by the efforts of James Watt, U.S. Secretary of the Interior, who believes that commercial interests should take precedence over the preservation of pristine wilderness areas and wildlife sanctuaries. The consequent loss, as populations approach extinction because of programs like decimation of habitats and predator control, is more than simply aesthetic: genetic material unique to each species will be lost forever. Particular issues of immediate concern are the fate of bobcats and whales, inhumane trapping, and the Endangered Species Act. As a longer-term concern, the goal of …
The Problem Of Pain: What Do Animals Really Feel?, Dana H. Murphy
The Problem Of Pain: What Do Animals Really Feel?, Dana H. Murphy
Sentience Collection
Much of the contention and confusion that seem inevitably to arise whenever the subject of pain in animals comes up appear to stem principally from problems with the word "pain" itself. When used to describe responses in humans, "pain" can mean any subset of an incredibly broad spectrum of sensations and emotions, ranging from the instantaneous, galvanizing effect of a dentist drill hitting the nerve in a molar, to more airy notions such as the "pain" of rejection or "painfully" embarrassing situations. Humans even use concepts as abstruse as the German term, weltschmerz, or "world pain," which denotes a vaguely …

Elevational Variations In The Lowest Limit Of Spartina Colonization In A Virginia Salt Marsh, Thomas G. Reidenbaugh, William C. Banta, Santoria Mendoza, Robert P. Strieter, Michele Varricchio
Elevational Variations In The Lowest Limit Of Spartina Colonization In A Virginia Salt Marsh, Thomas G. Reidenbaugh, William C. Banta, Santoria Mendoza, Robert P. Strieter, Michele Varricchio
Gulf and Caribbean Research
Elevations of lowest colonization of smooth cordgrass, Spartina alterniflora, were surveyed along the edge of a juvenile salt marsh at Wallops Island, Virginia. This lowest limit of Spartina varied over one-third of the local mean tidal range, with lowest occurrences between mean low water and mean low water neaps. Four geographical factors appeared to influence the lowest limit of Spartina: (1) tidal scouring in areas where tidal channels were constricted, (2) scalloping of the marsh edge over a sloping substrate, (3) patterns of historical development of the marsh, and (4) ice scouring of previously colonized Spartina over winter. …

Influence Of Cooperative Wildlife And Fishery Units On Graduate Education And Professional Employment, Rollin D. Sparrowe
Influence Of Cooperative Wildlife And Fishery Units On Graduate Education And Professional Employment, Rollin D. Sparrowe
United States Fish and Wildlife Service: Publications
In June 1982, several private conservation organizations will join the Iowa State University, and the Iowa Conservation Commission, in a 50-year celebration of the Cooperative Research Unit concept. The first Cooperative Wildlife Research Unit began there in 1932 in response to a recognized need for trained biologists and scientific information in the field of wildlife conservation. The unique partnership between federal, state, university, and private entities that resulted, evolved into the current nationwide program. There are currently 21 wildlife units, 26 fishery units, and 3 combined fish and wildlife units at 31 universities in 29 states (Figure O. The Fishery …
The Influence Of Salinity On Larval Development And Population Dynamics Of Anopheles Merus Dönitz (Diptera: Culicidae), F. W. Mosha, C. M. Mutero
The Influence Of Salinity On Larval Development And Population Dynamics Of Anopheles Merus Dönitz (Diptera: Culicidae), F. W. Mosha, C. M. Mutero
All Peer-Reviewed Publications
Variations in density of adults of Anopheles merus Dön. in Jimbo Village on the Kenya Coast were found to be correlated both with rainfall and with salinity at their breeding sites. Densities started to increase at the beginning of the rains when several breeding sites were formed. This was followed by a decline in numbers resulting mainly from the decrease in salinity in the semi-permanent breeding sites. A second rise occurred after the end of the rains, corresponding with an increase in salinity in the semi-permanent breeding sites due to evaporation. Peak density coincided with salinities of 30–50% sea water …
Vegetation Pattern And Disturbance Effects In The Subalpine-Alpine Interface, Valley Of The Ten Peaks, Alberta, Katherine J. Miller
Vegetation Pattern And Disturbance Effects In The Subalpine-Alpine Interface, Valley Of The Ten Peaks, Alberta, Katherine J. Miller
Theses and Dissertations (Comprehensive)
There have been several recent calls in the biogeography and vegetation ecology literature to investigate more thoroughly the role of recurrent disturbance or perturbation in the dynamics of subalpine communities, by assessing persistence and change in the dominant species population. In order to study the relationship between conifer regenerative effectiveness, disturbance effects, and the nature of the vegetation pattern, a field study was made of the vegetative cover (composition, abundance, dominance) and its performance (survival, vigour, and reproductive mode) in the upper subalpine zone in the Valley of the Ten Peaks, Banff National Park, Alberta. The occurrence of stresses and …
Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson
Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson
Marine Affairs Theses and Major Papers
Until the establishment of the Fishery Conservation and Management Act of 1976 (FCMA), fish outside the United States' twelve mile fishery zone were, according to international law, common property and belonged to the nation or individual that caught them. This common property law was based on the concept that fish resources were so large that no amount of fishing would interfere with the right of others to catch fish. Modern technology, however, has created equipment that enabled foreign and domestic fishermen to over-fish the resource. A reduced domestic catch led coastal fishermen to support a bill that unilaterally extended the …
Estimation Of Harvest Rate And Vulnerability From Age And Sex Data, J. E. Pahoheimo, David Fraser
Estimation Of Harvest Rate And Vulnerability From Age And Sex Data, J. E. Pahoheimo, David Fraser
Wildlife Population Management Collection
A nonlinear least-squares procedure is developed to estimate harvest rate and differential vulnerability in wildlife populations that are harvested with 1 segment of the population more able than another. The method requires age data by category from a series of harvests, plus information on accumulated harvest effort, and assumes that the nonharvest mortality rate is the same for the categories. The data need not be from consecutive harvests, as long as the effort is known for missing Monte Carlo simulations were done to verify the estimation procedure. An example shows the application of the method to moose (Alces alces) harvest …

An Interregional Study Of Kenya's Livestock Sector Using Linear Programming, Zakayo Joseph Mwangi
An Interregional Study Of Kenya's Livestock Sector Using Linear Programming, Zakayo Joseph Mwangi
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The major purpose of this study was to determine the least-cost method of producing red meat in Kenya. Linear programming was used in the study. A simulated reduction of grazing land available in one of the settlement areas was carried out to indicate what effect this had on the overall regional production pattern of meat in the country.
Kenya was divided into eleven livestock producing and consuming regions. 1979 was used as the base year, and the demand projection was based on the 1979 population. Input and output coefficients, livestock unit requirements, and market prices were developed. A linear programming …

Location Value Of Milk, Martin K. Beutler
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Due to the growth of milk marketing areas in the Intermountain West, a study was made to determine the most advantageous allocation of producer milk to twelve selected processing demand areas and to calculate location differentials between these same markets. A theoretical determination of location differentials and of the allocation of milk supply areas to processing centers were made using supply-push and demand-pull price alignment models developed by Associated Milk Producers, Inc., for the months of November 1979 and June 1980. Grade A producer mil k from the six member cooperatives of Western Dairymen' s Cooperative, Inc., was used in …
