Development Of A Combined Quantity And Quality Model For Optimal Management Of Unsteady Groundwater Flow Fields, R. C. Peralta, J. Solaimanian, C. L. Griffis

Arkansas Water Resources Center Technical Reports

Presented are alternative techniques for including conservative solute transport within computer models for optimizing groundwater extraction rates. Unsteady two-dimensional flow and dispersed conservative solute transport are assumed. Comparisons are made of the practicality of including modified forms of implicit and explicit finite difference solute transport equations within optimization models. These equations can be calibrated and subsequently used within a MODCON procedure. The MODCON modelling procedure consists of an integrated series of five optimization or simulation modules. The procedure is applicable for either an entire aquifer system or for a subsystem of a larger system. The first module, A, computes physically …

Results should provide valuable information concerning natural seagrass renewal and rates of seagrass growth. Such information is much needed in order to make sound decisions concerning seagrass restoration and viable mitigation options.

Use Of Recirculation Reactor To Study Biodegradation Of Aroclor 1242, A Polychlorinated Biphenyl, Babu S. Sanji

Theses

The performance of immobilized microorganisms in the detoxification of hazardous waste was investigated using a recirculation flow reactor, run in a batch mode. A mixed microbial population from a wastewater treatment plant was immobilized in calcium alginate gel. The bio-oxidation ability of these microbes towards a model toxin Aroclor 1242 (R) (PCB 1242) was studied.

A non-ionic surfactant (Triton X-405 (R)) was used as a medium in the enhancement of the solubility of Aroclor 1242 in aqueous phase.

Dissolved oxygen concentration was monitored using a flow Clark-type dissolved oxygen probe. Oxygen consumption was compared to the biodegradation of Aroclor 1242. …

Pentachlorophenol And Oxygen Consumption Of Immobilized Mixed Bacterial Culture, Tesfamariam Stephanos Tsadwa

A Model Of Energy Expenditure In White-Tailed Jackrabbits (Lepus Townsendii) Based On Integrated Studies Of Energetics And Field Ecology, Gordon L. Rogowitz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field and laboratory studies were conducted to develop a model of energy expenditure in a population of white-tailed jackrabbits (Lepus townsendii). Field work in southwestern Wyoming during 1985-87 showed that the breeding season commenced at snowmelt and ceased during late- July drought. Adult females reproduced relatively synchronously and produced a mean of three litters annually. Greatest fetal production occurred in the second litter period. Collections indicated a 1:1 sex ratio, few jackrabbits >2 years-old, and a density of 7 animals / km² in the population. Postnatal growth was sigmoidal, culminating in heavier adult females than males. Using …

Attitude Change Toward Vertebrate Pest Control, Robert M. Timm, Sanford D. Schemnitz

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Attitudes of students enrolled in courses on wildlife damage control at two universities were surveyed at the beginning and end of the semester. Attitudes toward wildlife and acceptance of various damage control methods were quantified and compared to responses obtained from the general public in previous surveys. As a result of the class, both groups of students generally became more accepting of current vertebrate control practices, including toxicant use. Student attitudes, as a result of knowledge gained, came to be more realistic and practical. We believe that persons, when presented factual information about wildlife damage and its control, will …

Photonovels Produced By Client/Professional Partnerships: An Educational Approach To Commensal Vertebrate Ipm, Stephen C. Frantz, John P. Comings, Debra L. Roter

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Since commensal vertebrate pest problems are largely "people problems," a well-planned and executed educational intervention could be the single most important component in an integrated pest management (IPM) program. The basic purpose of educational interventions is to bring sufficient information and understanding to affected clients so that they can and will intercept and control pests in the infested habitat. The encouragement of client participation in producing educational materials is consistent with learning theory and pest management principles. Such production methods allow materials to be closely aligned with client concerns and establish a climate for mutual exchange of ideas between …

Activity Of Lm 2219 (Difethialone), A New Anticoagulant Rodenticide, In Commensal Rodents, J. C. Lechevin, Richard M. Poche

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Preliminary studies completed on commensal rodents with the new anticoagulant rodenticide difethialone showed very good efficacy, such that 25 ppm baits could be used effectively. New test results presented in this publication confirm the activity as shown under laboratory conditions in choice tests, which represent more severe conditions, as well as its effectiveness against rodents that are resistant and non-resistant to warfarin. In tests where the palatability was only fair the chemical activity resulted in excellent mortality. In a field test against a large population of Mus musculus the results proved very satisfactory. Difethialone is toxic to birds and …

Efficacy And Environmental Impact Of Flocoumafen (Storm) Wax Block Baits Used For Rice Field Rat Control In The Philippines., Melanda M. Hoque, Jaime L. Olvida

Vertebrate Pest Conference Proceedings: 13th (1988)

Two large (approx. 160 ha) trial sites incorporating ricefields and village housing were selected in Laguna Province, Philippines. Flocoumafen 3.5-g wax block baits (StormR) were applied to one site, initially as two area-wide pulses of 80 to 100 blocks/ha and later as spot treatments, to areas of particularly high rat infestation. Baiting in and around the village houses was already carried out during the first two applications. On average, only 1.175 kg/ha/season of flocoumafen block bait gave good rodent control resulting in significant decreases in crop damage (% cut tillers) compared to the untreated area. The overall yield increase was …

The Biology Of Domestic Rats: Telemetry Yields Insights For Pest Con¬Trol, Michael A. Recht

Vertebrate Pest Conference Proceedings: 13th (1988)

In previous studies Norway and roof rats were captured, fitted with radiotransmitter collars, and released into their respective habitats. Detailed observations were made of their locomotor patterns, home ranges, activity phasing, food sources, and general behavior. A summary of micro-ecology, habitat partitioning and other behaviors from those studies which may be of use to persons interested in vertebrate pest control is reported.

Rodenticide Residues In Animal Carcasses And Their Relevance To Secondary Hazards, C. Raymond Record, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 13th (1988)

Some complexities and limitations of using carcass residue data to determine secondary hazard to nontarget species are discussed. The roles of chemical and toxicological properties of the rodenticide such as metabolism, excretion, organs of retention, site of absorption and latent period in secondary hazard are reviewed and examples given. The possible effects of bait composition and application methods, the behavioral response of the nontarget species, and local environmental factors upon secondary hazard are outlined.

Badgers (Taxidea Taxus) As Occasional Pests In Agriculture, Steven C. Minta, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 13th (1988)

The badger (Taxidea taxus). because of its strong propensity for digging, is considered North America's fossorial carnivore, feeding mostly on ground squirrels, pocket gophers, and mice throughout much of the western and midwestern continent. Badger excavations, primarily in search of food, produce mounds and deep holes which can damage alfalfa and other crops and damage farm equipment and water systems. Depredations include poultry, waterfowl, and eggs. Overall, the badger is considered a relatively minor vertebrate pest. As a furbearer it is considered a renewable natural resource. Most local pest problems are currently reduced through leghold trapping and shooting. Habitat modification …

M-44 Sodium Cyanide Ejectors In The Animal Damage Control Program, 1976-1986, Guy Connolly

Vertebrate Pest Conference Proceedings: 13th (1988)

This paper summarizes Animal Damage Control (ADC) program records relating to M-44 use during Fiscal Years 1976-86. During these years, M-44s were used in 14 western states to take 103,255 animals, including 92,843 coyotes, 5,544 other target canids, and 4,868 nontarget animals. More animals were taken in Texas than in all other states combined. Program-wide during FY1977-81, M-44 effort averaged approximately 5,600 unit years annually and 1.2 target animals were recovered per M-44 year.

Field Evaluation Of Padded Jaw Coyote Traps: Effectiveness And Foot Injury, Samuel B. Linhart, F. Sherman Blom, Gary J. Dasch, Richard M. Engeman, Glenn H. Olsen

Vertebrate Pest Conference Proceedings: 13th (1988)

A field study of unpadded and padded foothold coyote traps was undertaken in six western states in 1986-1987. Tests were designed to determine the capture efficiency and extent of foot injury caused by different trap modifications. Results were similar to an earlier study undertaken in 1984-85 that showed padded traps reduced foot injury but captured and held fewer animals than did unpadded traps. Both studies showed that unpadded long-spring traps used operationally by Federal Animal Damage Control specialists were the most effective (75-78% capture rate) but caused more foot injury. Padded long-spring traps were intermediate in efficacy (52-57%) and foot …

Prolonged Seed Handling Time Deters Red-Winged Blackbirds Feeding On Rice Seed, Dennis Daneke, David G. Decker

Vertebrate Pest Conference Proceedings: 13th (1988)

Theoretical concepts from foraging ecology were studied to identify elements of blackbird foraging strategies that may be manipulated to deter blackbirds feeding on rice. Seed-handling time was identified as one such vulnerable element. Consequently, we developed seed coatings for rice that increased handling time per seed, allowed a satisfactory germination rate, and persisted for several days postplanting. Test coats included hydrophilic binders with several starches, clays, plaster of paris and chemical grout in various combinations. Consistent repellency was achieved in feeding trials with captive red-winged blackbirds.
