Modeling Surface And Subsurface Stormflow On Steeply-Sloping Forested Watersheds, Patrick G. Sloan, Ian D. Moore, George B. Coltharp, Joseph D. Eigel

KWRRI Research Reports

A simple conceptual rainfall-runoff model, based on the variable source area concept, was developed for predicting runoff from small, steep-sloped, forested Appalachian watersheds. Tests of the model showed that the predicted and observed daily discharges were in good agreement. The results demonstrate the ability of the model to simulate the "flashy" hydrologic behavior of these watersheds.

Five subsurface flow models were evaluated by application to existing data measured at Coweeta on a reconstructed homogeneous forest soil. The five models were: Nieber 's 2-D and 1-D finite element models (based on Richards' equation), the kinematic wave equation, and two simple storage …

The Induction Of Tolerance To Heavy Metals In Natural And Laboratory Populations Of Fish, Wesley J. Birge, William H. Benson, Jeffrey A. Black

KWRRI Research Reports

Aquatic toxicity studies were performed on two natural populations of fathead minnows. One group of organisms was taken from a metal-contaminated flyash pond associated with a coal-fired power plant and the other group was collected from relatively uncontaminated hatchery ponds. Acute tests indicated that flyash pond fish were significantly more tolerant to cadmium and copper than were hatchery fish. At an exposure concentration of 6.0 mg Cd/L in moderately hard water, the median period of survival for flyash pond fish was 50.0 hr compared to 6.8 hr for hatchery fish. Both groups of organisms were about equally sensitive to zinc. …

Baseline Study For Monitoring Variations In Nitrate Concentration In Surface Waters Of Cuyamaca Rancho State Park In Relation To Watershed Types, Lester E. Harris Iii

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to compare the variations in nitrate concentration in the surface waters of five different watershed community types at Cuyamaca Rancho State Park. Monthly water samples were collected at selected sites below each watershed and analyzed by use of a specific ion electrode for nitrate concentration. Results indicate that variations in nitrate concentration are influenced by seasonal variation in rainfall. The yellow pine forest/chaparral watershed showed the highest mean nitrate concentration, three to four times higher than the other watershed types analyzed. Peak nitrate concentrations did not approach the maximum safe limit for human or …

Survival Analysis For A Red Squirrel Population, Curtis H. Halvorson, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

A 13-year study of an isolated red squirrel (Tamiasciurus hudsonicus) population in Montana has provided the data necessary to analyze their survival. Such long-term, intensive studies of wild populations are rare. When reported, derived (ratio) estimates are used to develop survival information as Gross et al. (1974), and Keith and Windberg (1978) did in respective 9- and 15-year lagomorph studies. A more accurate method, following cohorts, was used by Armitage and Downhower (1974) and Mosby (1969), who presented results for six or more year-classes of sciurids in actuarial tables (Deevey, 1947; Allee et al., 1949).

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 …

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 …

Input And Distribution Of Sewage Derived Sedimentary Material Adjacent To Chesapeake-Elizabeth Sewage Outfall, Virginia Beach, Virginia, Robert Carroll Brown

OES Theses and Dissertations

The concentrations of coprostanol and hydrocarbons were measured in the effluent from the Chesapeake-Elizabeth sewage treatment plant and surface sediments from the area surrounding the effluent discharge site. Most of the coprostanol (>84%) and hydrocarbons (>91%) were associated with particulates in the effluent. Some of these particles were incorporated into the sedimentary column within the study area, while some may have escaped from the area.

The study area is found to be a dynamic area where changes in the percentage and distribution of fine-grained sediments occur over periods of months. The movement of fine-grained sediments is an important …

Economics Of Microtus Control In Eastern U.S. Orchards, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

Chemical methods were found to be less expensive for control of voles (Microtus spp.) in orchards than the use of clean culture (combinations of herbicides, mowing, and cultivation). Ground cover sprays of hexachloroepoxyoctahydro-endo-endo-dimethanaphthalene (Endrin) or 2-[(p-chlorophenyl) phenylacetyl-l,3-indandione (Chlorophacinone, CPN, Rozol) required greater equipment and pesticide costs than hand placed or broadcast baits. Since active ingredient rates for ground cover sprayed chemicals may be 100-400 times that for hand placement or broadcast baiting, the costs for any new ground spray will likely be too expensive to be practical. Broadcast baiting, while less labor intensive than hand baiting, was found to be …

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 …

Acceptability Of Six Candidate Groundcovers To Meadow Voles, Edwin Lewis, Donald H. Rhodes, Milo Richmond

Eastern Pine and Meadow Vole Symposia

Meadow vole food preferences were examined by means of a series Of two day trials where pairs of plants were offered. Of the six plants tested, three (white clover, red clover, alfalfa) were found to be highly preferred by the voles, one (red fuscue) was acceptable, and two species (myrtle and crownvetch) were unacceptable. The results suggest that the undesirable groundcovers may be used as a deterrent to the establishment of meadow vole populations.
