How Amaranth Grain Affects Total Body Weight And Major Organ Weight In The Mongolian Gerbil, Rhoshonda Montgomery- Conway

McCabe Thesis Collection

Purpose and Objectives

The purpose of this research is to determine effects of amaranth grain of the body weight and organ weight of the Mongolian gerbil. The literature research indicates that amaranth results in physiological changes that appear to be species-specific rather than general. Since the gerbil is a granivorous animal, it is hypothesized that amaranth will be completely digested and that its nutritional quality will maintain normal to increased growth. While the results of this study cannot be applied to other animals, information has been gained with regard to the influence of amaranth grain on the Mongolian gerbil.

The Response Of Five Tropical Plant Species To Natural Solar Ultraviolet-B Radiation, Peter S. Searles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tropical regions currently receive the highest global levels of solar ultraviolet-B radiation (UV-B, 280-320 nm) even without ozone depletion. Thus, the influence of natural, present-day UV-B irradiance in the tropics was examined for five tropical species, including three native rainforest tree species and two economically important species. Solar UV-B radiation conditions were obtained vi using either a UV-B excluding plastic film or a near-ambient UV-B transmitting film in a small clearing on Barro Colorado Island (BCI), Panama (9 ° N). Significant differences were often exhibited as increased foliar UV-B absorbing compounds, increased leaf mass per area, and reduced leaf blade …

Miscellaneous Publication 10/94 - The Climate And Soils Of South-Western Australia In Relation To Vine Growing, J. S. Gladstones

Viticulture research reports

The vine industry in Western Australia is at present located mainly in the Swan Valley, some 15 miles inland from Perth. It produces currants for export, wine grapes, and table grapes for both local and export markets, in approximately that order of importance.

Climatically, the Swan Valley is well suited to vine fruit production. With an annual rainfall of about 34 inches, it has a mild, wet, almost frost-free winter, and a warm, dry summer. Olmo (1956) concluded that the Swan was especially well suited to the production of currants, table grapes and sweet dessert wines. However, he considered that …

The Prospects And Associated Challenges For The Biological Control Of Rodents, Grant R. Singleton

Vertebrate Pest Conference Proceedings: 16th (1994)

Biological control using macro- or micro-parasites is a promising research area for control of rodents. The largest impediment to progress is a dearth of high quality research, under field conditions, on wild rodents and their diseases. A major challenge is to identify a candidate control agent which is sufficiently pathogenic, has a high transmission rate and is target specific. Once this has been done, ecological studies of both the host and the disease agent, and of the epidemiology of transmission, are required. Whether the desired pathogenicity is via increased mortality and/or reduced fertility will depend on the agent and on …

Supplemental Bear Feeding Program In Western Washington, Georg J. Ziegltrum

Vertebrate Pest Conference Proceedings: 16th (1994)

Black bear (Ursus americanus) damage to trees is a severe problem in the Pacific Northwest. Significant damage has been observed for many years, especially in highly managed private industrial forests in western Washington. The introduction of intensive silvicultural techniques resulted in higher yields, but may have also made trees more vulnerable to black bear destruction. Early lethal control efforts lost public support and the forest products industry investigated different methods that concentrated on non-lethal management tools. In 1985, the Washington Forest Protection Association introduced supplemental bear feeding as a damage prevention program in high damage areas during the …

Bird Control In New Zealand Using Alpha-Chloralose And Drc1339, Peter C. Nelson

Vertebrate Pest Conference Proceedings: 16th (1994)

Horticulturists and the general public in New Zealand are experiencing increasing problems with a number of introduced bird species. This has meant that many people wish to carry out bird control operations themselves to reduce the problems these birds cause. Most of this control will have to be carried out by the growers themselves as there are very few professional bird control personnel in New Zealand. Alpha-chloralose is the only toxin the general public has access to for controlling birds. It is available in a variety of bait forms with a maximum toxic loading of 2% (weight/weight). Registered personnel can …

Predicting The Outcome Of Rodenticide Trials Against Norway Rats Living On Farms, Roger J. Quy, David P. Cowan, Peter Haynes, Ian R. Bmglis, Tom Swinney

Vertebrate Pest Conference Proceedings: 16th (1994)

Difenacoum and bromadiolone treatments against Norway rats may fail because: 1) the animals eat little or no bait, 2) reinvasion rapidly offsets any success, or 3) the population contains resistant individuals. By monitoring bait takes and employing independent measures of rat activity such as tracking plates, it is possible to identify, often in the early stages of a treatment, patterns that indicate the contribution of each of these causes to the eventual outcome. If there is no bait take from the majority of bait points visited by rats in the first week then the treatment is unlikely to be successful, …

Quality Wool Production At Lower Cost, Peter Metcalfe

Journal of the Department of Agriculture, Western Australia, Series 4

Low wool prices are forcing farmers to reduce their sheep management costs but, fortunately, cost cutting is not resulting in lower wool production, poorer wool quality or lessened sheep care on the best wool growing properties.

Wild Pigs, Reginald H. Barrett, Grant H. Birmingham

Prevention and Control of Wildlife Damage Handbook

Wild pigs (Sus scrofa) include both feral hogs (domestic swine that have escaped captivity) and wild boar, native to Eurasia but introduced to North America to interbreed with feral hogs. Christopher Columbus first introduced members of the family Suidae into North America in 1493 in the West Indies. A variety of habitats, from tidal marshes to mountain ranges, are suitable for wild pigs. Types of food vary greatly depending on the location and time of year. Wild pigs are intelligent animals and readily adapt to changing conditions. Wild pigs can cause a variety of damage. Wild pigs are …

An Inventory And Condition Survey Of The Murchison River Catchment, Western Australia, Peter James Curry, A L. Payne, K A. Leighton, P Hennig, D A. Blood

Technical Bulletins

The inventory and condition survey of the Murchison River catchment and surrounds, undertaken by the Department of Agriculture between 1985 and 1988, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed by field work during 1985-88 …

Deer, Scott R. Craven, Scott E. Hygnstrom

Prevention and Control of Wildlife Damage Handbook

Deer (Odocoileus virginianus) are probably the most widely distributed and best-recognized large mammals in North America. Deer are even-toed ungulates of the family Cervidae. The white-tailed deer is found in every state in the United States except perhaps Alaska and Utah. Deer are creatures of the forest edge rather than the dense, old-growth forest. Browse (leaves, stems, and buds of woody plants) is generally available all year and is a staple food for deer. Breeding occurs from October to January depending on latitude. Deer damage a wide variety of row crops, forage crops, vegetables, fruit trees, nursery stock, …

Elk, David S. Decalesta, Gary W. Witmer

Prevention and Control of Wildlife Damage Handbook

The elk is a large, powerful animal with an adult weight averaging over 400 pounds (180 kg). The Rocky Mountain elk (Cervus elaphus nelsoni) is found in the Rocky Mountain states and in scattered locations in the Midwest and East. Although elk once roamed freely into lower elevation grasslands, they are now found primarily close to heavily forested areas that are dotted with natural or human-made (clear-cut) openings. Elk graze on grasses and forbs, and browse on shrubs, tree seedlings, and saplings. Weather and human activities influence elk activity. Elk commonly impact agricultural resources by competing with domestic …

Waterfowl, Edward C. Cleary

Prevention and Control of Wildlife Damage Handbook

The term waterfowl is properly applied only to ducks, geese, and swans. In North America, most waterfowl are migratory, flying long distances in the spring and fall between the summer breeding grounds and wintering areas. Waterfowl, as their name implies, are most often found near water. The food of individual waterfowl species ranges from fish to insects to plants in various combinations, depending on availability. Waterfowl are normally monogamous and solitary nesters. Goose problems in urban and suburban areas are primarily caused by giant Canada geese, which are probably the most adaptable of all waterfowl. In the United States, migratory …

Alligators (Alligator Mississippiensis), Allan R. Woodward, Dennis N. David

Prevention and Control of Wildlife Damage Handbook

The American alligator (Alligator mississippiensis) is the most common of two crocodilians native to the United States and is one of 22 crocodilian species worldwide. The American alligator is found in wetlands throughout the coastal plain of the southeastern United States. Alligators can be found in almost any type of fresh water, but population densities are greatest in wetlands with an abundant food supply and adjacent marsh habitat for nesting. Alligators are exclusively carnivorous and prey upon whatever creatures are most available. Alligators are ectothermic — they rely on external sources of heat to maintain body temperature. Damage …

Winter Diet And Nutritional Condition Of White-Tailed Deer In The Northern Black Hills, South Dakota, Robert G. Osborn

Electronic Theses and Dissertations

Habitat deterioration in the northern Black Hills (NBH) of South Dakota may be responsible for declining white-tailed deer (Odocoileus virginianus) population levels (Griffin et al. 1992). Because of the relationship between habitat and nutrition, a two-year research project was initiated in January 1992 to evaluate the physical and nutritional condition of white-tailed deer inhabiting five NBH winter subranges. Habitat variables were measured at 100 random locations on each study area. Pellet groups were collected throughout each study area at two-week intervals during January, February, and March 1992 and 1993. Five female white-tailed deer were collected from each study area in …

A Trophic Gradient Analysis Of Lake Powell: The 1994 Utah State University Aquatic Ecology Laboratory Analyses, Wayne A. Wurtsbaugh, Megan Barker, Ron Brunson, David Fogle, Scott Hawxhurst, Chad Mellison, Lis Phillips, Felipe Queiroz, Daniel Zamecnik

Watershed Sciences Faculty Publications

From 9-11 April, 1994, the Aquatic Ecology Laboratory Class (FW462) of Utah State University sampled the upper reaches of Lake Powell to assess if a trophic gradient existed. We °ampled physical and chemical parameters (temperature, oxygen, conductivity, and total phosphorus), phytoplankton chlorophyll a, littoral and pelagic zooplankton biomass and composition, littoral and profundal benthic invertebrates, and fish abundance measured in the littoral zone (gill nets) and the pelagic zone (hydroacoustics). Data was collected along the upper 50 miles of the reservoir between Bullfrog and the Hite marina near the Colorado River inflow.

Our field trip was done just prior to …

Rejex-It'" Ag-36 The Gentle Way To Repel Geese From Golf Courses And Other Turf Areas, Peter F. Vogt

Great Plains Wildlife Damage Control Workshop Proceedings

Birds have always been a problem in agriculture, specially for berries and fruits. Farmers and home owners have been fighting these problems with limited success for centuries. However, the problems with birds on turf are relatively new and are not even known by many people. The "Complete Guide to Pest Control" (Ware 1988) does not even mention geese as a pest, or golf courses as an area of bird problems.

Status Of Selected Fishes In The Missouri River In Nebraska With Recommendations For Their Recovery, Larry W. Hesse, Gerald E. Mestl, John W. Robinson

Nebraska Game and Parks Commission: Staff Research Publications

Population density of five species of chubs and two species of minnows in the Missouri River in Nebraska has been reduced by as much as 95% since 1971. Burbot have been nearly extirpated, sauger have been greatly reduced, and blue catfish are rare. Reasons for the decline of these species include removal of snags from the river; cessation of organic matter and sediment transport because of the construction of large dams on the mainstem and tributaries; cutoff of floodplain connection through channelization, degradation, and the cessation of flooding; alteration of the natural hydrograph to meet the need for commercial navigation; …

The Development Of Contraceptive Methods For Captive Wildlife, Cheryl S. Asa

Contraception in Wildlife Management

Contraception has become critical in managing zoo populations, both to limit production of surplus animals and to promote genetic health. One role of the Contraception Advisory Group, formed in 1989, is to coordinate research to develop new contraceptive methods. Because melengestrol acetate (MGA) implants, which have been used by zoos for almost 20 years, recently have been associated with uterine pathology in felids, several new contraceptive techniques are being evaluated. These include other steroid hormone formulations, such as the birth control pill Depo-Provers®, the Norplant® implant, and MGA added to feed; bisdiamine, an oral male contraceptive; zona pellucida (ZP) vaccine; …

Rejex-It™Ag-36, A Potential Tool To Protect Seeds From Bird Depredation, Peter F. Vogt

Wildlife Damage Management Conference

The ever increasing bird populations (e.g., Black birds, geese etc.) are known to cause considerable losses to agriculture. This problem has reached serious proportions for crops that are farmed on large tracts and are seeded by aerial application such as rice and canola. ReJeX-iT™AG-36, a non-toxic, biodegradable bird aversion formulation, derived from food grade ingredients, has been proven in pen tests and field trials to be effective as a seed treatment to prevent birds from eating the treated seeds. The product does not harm the seeds or the effected birds in any way, even if ingested; it just makes the …

Can We Landscape To Accommodate Deer? The Tracy Estate Research Garden, Helen H. Heinrich, Susan Predl

Wildlife Damage Management Conference

The landscape of New Jersey is remarkably rich in vegetation and open space, despite the state's reputation as the nation's most populous state. This landscape is increasingly the product of intense interaction between the white-tailed deer (Odocoileus virginianus) and both native and cultivated vegetation, particularly in suburban communities, where both the whitetail and the vegetation coexist in abundance. Nearly extirpated at the tum of the century due to over-hunting, the state's white-tailed deer population today exceeds 140,000 because habitat is ideal and hunting seasons are carefully regulated. In many instances, where landowners choose not to use hunting as …

Balancing The Needs Of Society: Listening To The Public, Robert H. Schmidt

Wildlife Damage Management Conference

Wildlife damage management, as a professional activity, is involved in a broad range of management issues affecting agricultural productivity and profitability, human health and safety, and endangered and valued species management. Surveys by S. Kellert and others have indicated that the general public is agreeable to resolving wildlife damage issues, even utilizing lethal technologies. However, surveys and case histories have also indicated that the process involved in resolving wildlife damage issues invokes much public concern. By process I mean the specific methodologies, strategies, and resource and social tradeoffs involved in developing and implementing a wildlife damage management program.

Can We Landscape To Accommodate Deer? The Tracy Estate Research Garden, Helen H. Heinrich, Susan Predl

Eastern Wildlife Damage Control Conference: 6th (1993)

The Morris County Park Commission, manager of hundreds of acres of open space in this central New Jersey county, realized that the white-tailed deer residing on park land were having a detrimental effect on the vegetation on these properties. A Wildlife Management Advisory Committee to the Commission was formed to measure the dimensions of the problem and to find ways to mitigate the effects of the deer population of deer. One recommendation of the Committee was to determine if a landscape design could be developed to use plantings less attractive to the deer; planted in ways that might discourage heavy …
