Mathematical Programming Model Of Western Australian Dairy Farms, G R. Olney, D A. Falconer

Animal production and livestock research reports

A profit maximising mathematical programming dairy farm model has been developed which determines the most profitable management strategies for the full year. This model was initially an extension of the one used in the Western Australian Dairy Feed Management Service (DFMS) which determines the most profitable ration to feed for a specific period, the milk yield per cow and the number of cows to milk. The DFMS is useful for formulating a ration for a specific period, particularly during summer on non-irrigated farms in Western Australia when complete hand feeding is required, but it cannot be used to determine optimum …

Multiple Trophic Levels In Soft-Bottom Communities, John A. Commito, William G. Ambrose Jr.

Environmental Studies Faculty Publications

In order to assess the general applicability of recent field experiments with predatory infauna, we searched the literature and found 48 well-documented cases of infaunal consumption by such predators. In 63 % of the cases detailed enough to make a determination, the predators ate other predators. Multiple trophic levels within the infauna are probably a common feature of many soft-bottom communities.

Leachate Monitoring In Naturally Saline Groundwater Chesapeake Landfill Chesapeake Virginia, T. Britt Mcmillan

OES Theses and Dissertations

Groundwater chemistry around the Chesapeake municipal landfill was monitored over a one year period. Ten sample sites as well as two surface water sites were used to monitor water quality. Two wells, one at 3 m and the other at 10 m were located at each site. Surface water samples were taken from the Elizabeth River, north of the landfill, and a tidal channel, west of the landfill. Seven groundwater sites were downgradient of the landfill and three sites were upgradient (control sites).

The landfill overlies a tidal marsh, approximately 100 m south of the intracoastal waterway (Elizabeth River). Dredge …

Microbial Characteristics Of An Industrial Mixed Liquor After Exposure To Phenolic Compounds, Patricia L. Boyle

Theses

The microbial characteristics of a mixed population from the Passaic Valley Sewerage Commissioners (PVSC) Wastewater Treatment Plant in Newark were examined. This plant handles about 250 million gallons per day of mixed sewerage, with a large industrial component. The microbial species were characterized using standard plating techniques, morphology, microscopic observation, and biochemical tests. These characteristics were determined for the fresh liquor, and after successive batch exposure to phenol (100 ppm) and 2-chlorophenol (20 ppm). Predator/prey, gram positive to gram negative bacteria ratios, and the fungi and protozoan populations were also determined. These results were compared with those previously obtained using …

An Evaluation Of Visual And Auditory Electronic Devices To Repel Deer, R. Blake Roper, Edward P. Hill

Wildlife Damage Management Conference

An electronic devicethat emitted auditory and visual stimuli was evaluated for repelling deer from hardwood plantations and soybean fields in Southwest Alabama from February 1976 through March 1978. Repellent effectiveness in hardwood plantations and in soybean fields was determined by comparing browsing damage on areas treated with the repellent stimuli against damage on control areas.

No difference (P < 0.05) was detected in browsing damage between treated and control areas in either hardwood plantations or soybean fields. Browsing damage on soybeans continued when electronic stimuli were combined with electric fences, human scent rags, and periodic shooting, demonstrating the high degree of adaptability of the white-tailed deer as they attempt to utilize an available food supply.

The Role Of State And Wildlife Agencies In Wildlife Damage Control, Charles D. Kelley

Wildlife Damage Management Conference

The Alabama Game and Fish Division is responsible for the stewardship of the wildlife and fisheries resources in the state. Within this context and the cooperative efforts with other agencies that have dealings with animal damage, the Division develops, permits, approves and administers control of both game and nongame (except migratory) species of wildlife.

Animal control complaints fall into two major areas - crop damage and nuisance animals. Nuisance animals, with some exceptions, are bats, armadillos, alligators, woodpeckers, snakes, birds that roost or nest in rookeries. Squirrels, bears, rabbits are the cause of both nuisance and crop damage complaints. Deer, …

Reformulated 4-Aminopyridine Baits Cost-Effectively Reduce Blackbird Damage To Ripening Cornfields, Jerome F. Besser, John W. Degrazio

Eastern Wildlife Damage Control Conference: 2nd (1985)

In 1984 4-aminopyridine baits, stabilized with hydrochloric acid, were appraised in ripening cornfields being attacked by blackbirds on the Sand Lake National Wildlife Refuge., South Dakota. In 1982, i t had been discovered that 4-aminopyridine, the active agent in commercial Avitrol® baits for crop protection rapidly vaporized at summer storage and field baiting temperatures.

In July, baiting lanes were created in 12 cornfields by destroying every 55th row. In August after a 3-day pretreatment period, fields were baited with Avitrol® FC Corn Chops-99 for a 2-week period when corn was most vulnerable to damage. Bait was applied from baiting lanes …

Birds In Hangars - A Messy Problem, Albert E. Bivings Iv

Eastern Wildlife Damage Control Conference: 2nd (1985)

Pest birds in hangars and similar man-made structures pose specific health hazards as well as nuisance and corrosion problems. While lethal control or a scaring program may be the best technique for some locations, neither address the long-term problem of the basic attractiveness of these structures to birds. The best long-term solution usually is to exclude the birds with permanently installed plastic or nylon netting. Several methods to accomplish this are discussed.

Public Tolerance Of A Suburban Deer Herd: Implications For Control, Daniel J. Decker, Thomas A. Gavin

Eastern Wildlife Damage Control Conference: 2nd (1985)

Suburban deer populations have been increasing in the eastern U.S., resulting in deer-human conflicts that can not always be resolved by a traditional management approach., Professionals responsible for management of deer damage (herd control and extension education) need information on the extent and nature of deer damage in suburban situations. Attitudes of suburban residential property owners about wildlife in general and deer in particular must be identified so that control measures that are socially acceptable as well as biologically feasible can be formulated o People's tolerance of deer damage and their propensity for undertaking on-site preventive measures need to be …

An Investigation Of Techniques Used To Discourage Rebuilding Of Beaver Dams Demolished By Explosives, James M. Dyer, Charles E. Rowell

Eastern Wildlife Damage Control Conference: 2nd (1985)

One hundred seventeen beaver dams were partially or wholly demolished with explosives from April through August between 1982 and 1984. These dams were of two types; shallow water dams found in areas of flat terrain, and deep water dams found in major creek channels or in areas of hilly terrain. Following demolition, various treatments were applied to the dam sites to try to retard rebuilding. Our conclusions are that deep water dams can be removed more effectively than shallow water dams and that late summer removals were rebuilt less frequently than early and midsummer removals. Also, certain types of repellents …

Current Status Of Deer Fencing In The Northeast, Mark R. Ellingwood, Jay B. Mcaninch, Michael J. Fargione

Eastern Wildlife Damage Control Conference: 2nd (1985)

The recent development of high tensile electric fencing for controlling deer damage has led to the installation of these fence designs throughout the Northeast. In May 1984. 55 surveys were sent to individuals in 10 states who were known to have recently constructed deer fences. Sixty-seven percent of the surveys were returned and a variety of fence-related data were generated. These include information on deer damage, a general description of fence designs being utilized, information concerning fence voltage, data on fence maintenance and several questions on fence performance, owner satisfaction, and the cost/benefits of deer damage control. The majority of …

Wildlife Damage Control And The Wildlife Society, Thomas M. Franklin

Eastern Wildlife Damage Control Conference: 2nd (1985)

Wildlife damage control is recognized by The Wildlife Society as an essential and responsible segment of the wildlife profession. At least since 1959, Society committees have addressed elements of wildlife damage control (although wildlife damage control was not always the specific term used). The Wildlife Society Council first approved an "Animal Damage Control" position statement in 1968. In March 1985, Council updated and renamed it "Wildlife Damage Control" to emphasize our positive approach to this important segment of wildlife management. The official position statement was published in The Wildlifer (May-June 1985) and is reprinted below.
