Artificial Floating Islands: Cities Of The Future, Earl A. Proetzel

Marine Affairs Theses and Major Papers

This report will investigate the feasibility of large-scale artificial floating islands, to solve problems posed by over-population and environment-burdening activities in coastal areas. The investigation will focus on the historic, technical, utilizable and legal aspects of artificial floating islands. Although this report exemplifies artificial floating islands developed for offshore cities, electrical power generation and basing for the military, its content is applicable to any offshore floating development.

Nothing Succeeds Like Succession: Ecology And The Human Lot, James A. Macmahon

Faculty Honor Lectures

An Honor Lecture provides a rare opportunity for me as a scientist. First, I have the chance to share, and in a sense to justify, my chosen and cherished discipline, ecology, before an eclectic audience. Second, I have a reason to consider my profession in a broader perspective than I normally do, given the pressures of day-to-day teaching, of grantsmanship, and of acting the role of stern taskmaster to my graduate students. I relish the opportunity to dabble, with an ecological perspective, in history, in philosophy, and in other areas. First, I will discuss my discipline in the context of …

Disposal Of Household Wastewater In Soils Of High Stone Content (1977-1980), E. M. Rutledge, C. R. Mote, M. S. Hirsh, H. D. Scott, D. T. Mitchell

Arkansas Water Resources Center Technical Reports

Two experimental septic tank filter fields were constructed with built-in monitoring equipment in Nixa soils. These soils contain many chert fragments and a fragipan about 60 cm deep which restricts downward water movement and is the design-limiting feature. The standard filter field (76 cm deep) was built into the fragipan and the modified standard filter field (30 cm deep) was placed above it. During 30 months' observation, the modified standard performed better than the standard filter field. Maximum rise of effluent in the standard and modified standard came within 11 and 19 cm of the soil surface, respectively. Performance of …

Effects Of A Wildfire On Seed Rain And Soil Seed Reserve Dynamics Of A Good Condition Sagebrush-Grass Rangeland In Central Utah, Mohamed Ali Hassan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objectives of this research were to investigate the ecological importance of soil seed reserves and seed rain on regeneration of a good condition sagebrush-grass range vegetation after a wildfire and draw conclusions leading to better understanding and management of such ecosystems. Investigations were conducted for two successive years on a community where major plants were neither rhizomatous nor sprouting. In such cases soil seed reserves and seed rain have to be the main source of regeneration. In addition to monitoring soil seed reserves and seed rain, vegetation changes during the past two years and the historical conditions of the …

Polychlorinated Biphenyl Levels In The Ocean Scallop (Placopecten Magellanicus) Gmelin From The Philadelphia Sewage Sludge Disposal Site, Guy Jeffrey Hall

OES Theses and Dissertations

Ocean Scallops (Placopecten magellanicus) were sampled from stations in and around the Philadelphia Disposal Site. Each sample was dissected and aliquots of adductor muscle and reproductive tissue were chemically extracted for Polychlorinated Biphenyls (PCBs). A perchlorinated procedure outlined by Diosady et al., 1972, Aromour, 1973 and Crist et al., 1977 was employed to increase detection levels and simplify quantitation of PCBs. PCB levels were reported in dry weight and lipid weight of both adductor muscle and reproductive tissue. Findings indicated residual levels or PCB/lipid weight increased as lipid levels decreased in both tissue types. Levels detected in all adductor muscle …

Economics And Control Of Damage Caused By Low-Density Populations Of Meadow Voles In Ontario Apple Orchards, Ronald J. Brooks, Stephen A. Struger

Eastern Pine and Meadow Vole Symposia

Live trapping and questionnaires were used to evaluate amount, distribution, and costs of control of damage to Ontario apple trees by meadow voles (Microtus enns lvanicus) in 1981-82. In a sample of 180 orchards, 5802 (0.77%) trees were damaged or killed by voles. Orchards with high levels of damage (> 2.5%) were smaller than the average orchard in our sample. Application of rodenticides showed no relationship to levels of damage, but was effective in short-term population reduction. Growers spent an average of $17/ha on rodenticides and $38/ha on herbicides, and they estimated that voles destroyed 2% of their crop each …

Effect Of 6-Mboa On Microtus Pinetorum And Microtus Pennsylvanicus Of Different Ages, J. A. Cranford

Eastern Pine and Meadow Vole Symposia

Short-lived small rodents require environmental cues to synchronize their breeding with optimal environmental conditions. In the absence of such cues animals would waste a large portion of their reproductive effort when environmental conditions were unfavorable. Rowan (1938) noted that endocrine systems regulating mammalian reproduction responded to the environmental photoperiodic cues. Bodenheimer (1946) observed that major outbreaks of voles in Palestine could not be correlated with environmental factors such as climate, photoperiod, volume of food resources, or population density, acting either alone or in combination. From those studies he suggested that vole outbreaks were associated with an unknown factor or factors …

Effect Of Group Size On Body Weight In Different Thermal Environments For Microtus Pinetorum, J. A. Cranford, N. N. Thumser

Eastern Pine and Meadow Vole Symposia

Seasonal variation in growth rates has been well documented in some small rodents (Kubik, 1965; Brown, 1973; Iverson and Turner, 1974; Peterborg, 1978; Pistole and Cranford, 1983). During winter juveniles tend to show little or no growth; however, Kubik (1965) found that Cleithronomys glareolus born in late fall went through a two-phase growth pattern. Growing rapidly until winter and then resuming rapid growth the following spring. Additionally, Brown (1973) has reported the same two-phase growth in Microtus pennsylvanicus. Iverson and Turner (1974) demonstrated that Microtus pennsylvanicus adults showed a loss of weight during winter, and Pistole and Cranford (1983) have …

Effects Of Coprophagy In Microtine Rodents, Jack A. Cranford, E. O. Johnson

Eastern Pine and Meadow Vole Symposia

Digestion and assimilation strategies of herbivorous mammals are diverse but fall into two major categories (Moir, 1968; Gartner and Pfaff, 1979; Hume and Warner, 1980). The most complex of which occurs in the lagomorphs and has been well studied. In contrast rodents exhibit great variability in diet and nutritional biology (Landry, 1970; Baker, 1971; Kenagy and Hoyt, 1980). Early reports of coprophagy by rodents were incidental or descriptive, and indicated it was infrequent (Howell and Gersh, 1935; Ingles, 1961; Wilkes, 1962; Hoover et al., 1969; Jarvis, 1981). Rats mechanically prevented from reingesting feces showed reduced growth rates (Barnes et al., …

Regulation Of Reproduction In An Outbred Colony Of Pine Voles, John J. Lepri

Eastern Pine and Meadow Vole Symposia

Pine voles (Microtus pinetorum) cause economic losses to orchardists in the eastern United States by gnawing on the roots of fruit trees. Although they are small in body size, their impact on orchards can be quite substantial: in 1979 half of the annual mortality of apple trees in Henderson County, North Carolina, was attributed to vole damage (Sutton et a1 1981). Rodenticide application integrated with cultural management is currently regarded as a good combination for controlling vole populations in orchards. However, this solution to the vole problem is incomplete because poisons may unintentionally harm non-target organisms (Hegda1, Gatz & Fite …

Movements Of Meadow Voles In Winter: Implications For Vole Management In Orchard Habitat, Dale M. Madison, Randall W. Fitzgerald, William J. Mcshea

Eastern Pine and Meadow Vole Symposia

The movements of meadow voles in a field population were studied using radiotelemetry during fall and winter. The voles changed from a dispersed, solitary dispersion pattern during early autumn to social clusters with communal nesting during winter. This shift occurred as the daily median temperature approached freezing. Movement was inhibited and localized during winter, except under snow when the voles exhibited a freedom of movement not experienced during other times of the year. Overwinter management of meadow voles in orchard habitats is discussed in view of these findings.

Movements And Habitat Use By Pine And Meadow Voles In An Orchard, Ralph E. Pagano

Eastern Pine and Meadow Vole Symposia

Several radiotelemetry studies have now been completed in the orchards of the mid-Hudson Valley, New York. The results of one of these projects, a l2-month study of the movements and habitat use of pine and meadow voles, will be reported on here. The success of an integrated vole management program using cultural practices and rodenticides depends a great deal on knowing the movements and habitat use of the two orchard vole species. Species interactions that could lead to differential use of the orchard habitat are another important element in a vole management program. This study focused on three major objectives: …

The Efficacy Of Several Broadcast Rodenticides In The Mid-Hudson Valley, New York, Ralph Pagano, Jay Mcaninch

Eastern Pine and Meadow Vole Symposia

As summarized by LaVoie and Tietjen (1978), many aspects of vole control using rodenticides including the costs/benefits of rodenticide use, applicator limitations in commercial orchards, and vole biology have not received proper attention. Data relating vole population levels to damage severity have not been generated and thus the exact benefits of control measures are difficult to analyze. Several aspects of vole biology have only recently been considered in rodenticide application procedures. Problems such as bait acceptance and percentage population control have created disparity in several rodenticide experiments (Richmond et al., 1978). A knowledge of vole use of vegetative cover and …

The Influence Of Soil Moisture, Texture, And Temperature On Nest-Site Selection And Burrowing Activity By The Pine Vole, Microtus Plnetorum, Donald H. Rhodes, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

Pine voles (Microtus pinetorum) have long been recognized as a pest species in fruit orchards of the eastern United States (Hamilton 1935). These semifossorial rodents construct tunnel systems beneath apple trees where they eat entire roots or strip roots of bark and cambium. Hamilton (1938) reported numbers of pine voles within apple orchards as high as 200-300 voles per acre which is in sharp contrast to the relative scarcity of pine voles outside orchard situations (Crain and Packard 1966; Goertz 1971), These findings suggest that orchard habitat provides excellent conditions for pine vole growth and reproduction, although the specific components …

Social Influences On Reproduction In Pine Voles, Margaret H. Schadler

Eastern Pine and Meadow Vole Symposia

The presence of large populations of pine voles in apple orchards suggests that in the field reproduction of these pests has few constraints. Yet, evidence collected from our colony at Union College indicates that in the laboratory reproduction is not at random but instead is socially restrained and predictable. Unless these findings are artifacts of laboratory life, they may help explain some of the data collected in the field. Horsfall (1963) trapped voles every month of the year from an orchard near Cloverdale, VA. Since he found pregnant females in all collections, he concluded that reproduction occurred throughout the year …

Highlights Of The Seventh Eastern Pine And Meadow Vole Symposium, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

The Seventh Eastern Pine and Meadow Vole Symposium was held at the Cliffside Inn, Box 786, Harpers Ferry, West Virginia, March 3-4, 1983 for the purpose of assessing the current status of research, extension, and industry programs relating to vole damage to fruit trees. The meeting was held to provide a problem solving atmosphere in which growers, governmental agencies such as EPA, USDA, USDI, the chemical industry, and university personnel could observe the current thrusts of research and extension programs and their impact on future control strategies.

Nutrients And Acid In The Rain And Dry Fallout At Fayetteville, Arkansas (1980-1982), George H. Wagner, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

Wet and dry fallout at Fayetteville, Arkansas have been collected separately and analyzed since April, 1980. The precipitation-weighted-average pH for two yearly periods of rainfall were 4.72 (6/80-5/81) and 4.75 (6/81-5/82). This corresponds to a concentration of the acid ion, H+, of about 18 parts per billion (ppb). Pure water in equilibrium with the CO2 of the air would have a pH of 5.65 (2.2 ppb of H+). The range of pH during this two year period was 3.86-7.74(140-0 ppb H+) for the rainfall. Aqueous extracts of the dry fallout were always in the 6.75-7.87 pH range, i.e., neutral to …
