A Laboratory Study Of Nongenetic Embryonic Adaptation To Salinity And Its Subsequent Effects Upon Larval Development Of The Grass Shrimp Palaemonetes Pugio Holthius, Paul Jay Anninos

OES Theses and Dissertations

Fertilized embryos of the grass shrimp Palamonetes pugio Holthuis (Decapoda; Caridea) were exposed to two levels of salinity [5 ppt (exposed) and 20 ppt (control)] during incubation to determine the extent to which embryonic adaptation influences subsequent larval development. Larval response to embryonic exposure was measured at three salinities (5 ppt, 10 ppt, and 20 ppt) as the fraction of larvae surviving to metamorphosis and the duration (in days) of larval development. The survival rate of larvae hatched from control, or non-adapted, embryos was significantly influenced by rearing salinity. The differences in survival of pre-adapted larvae (exposed group), however, were …

A Comparison Of Maternal Behavior In Three Species Of Voles (Microtus Pennsylvania, M. Pinetorum, And M. Ochrogaster) Using A Laboratory System, B. A. Mcguire, M. A. Novak

Eastern Pine and Meadow Vole Symposia

A system has been developed to describe and compare the maternal behavior of three species of microtine rodents within a naturalistic environment. The apparatus consists of two Interconnected Plexiglas-based tables with a peat substrate and hay cover. A pregnant female and her mate are placed within the tables, once the female has shown a thirty percent weight gain and pups can be felt by palpating her abdomen. Maternal behavior, as well as male-female interactions and information on pup physical and behavioral development, are recorded daily for twenty-five days immediately following parturition. Unrestricted observation of female behavior during neonatal, pre-weaning and …

Bromethalin: A Promising New Rodenticide, William B. Jackson, S. R. Spaulding, R. B. L. Van Lier, B. A. Dreikorn

Vertebrate Pest Conference Proceedings: 10th (1982)

Bromethalin is a unique highly potent rodenticide exhibiting a mode of action different from anticoagulant rodenticides. Bromethalin provides a lethal dose to rodents in a single feeding with death generally delayed two to three days. Rodents do not discriminate against bromethalin bait; therefore, excellent bait acceptance is achieved with no prebaiting. Field studies have shown bromethalin bait to be highly efficacious against Norway rats and house mice under a variety of field conditions. Laboratory and field trial data indicate bromethalin is effective against known anticoagulant–resistant rodent populations. Toxicological data indicate bromethalin bait is relatively safe to nontarget species as well …

The Role Of Usda In Animal Damage Control, James E. Miller

Vertebrate Pest Conference Proceedings: 10th (1982)

The impact of vertebrate animal damage on agricultural production of row crops, forests, horticulture, poultry and livestock production, other wildlife, health of humans and domestic animals, and the protection of human interests is a vital concern of the U.S. Department of Agriculture. The Department recognizes that it is an old and complex problem that does not lend itself to easy answers. Animal damage problems will continue to be a significant concern of USDA and will probably always be controversial, requiring intensive research, educational, regulatory, and assistance programs. The objectives of the Department are to develop and maintain viable programs in …

Guard Dogs And Gas Exploders As Coyote Depredation Control Tools In North Dakota, William K. Pfeifer, Michael W. Goos

Vertebrate Pest Conference Proceedings: 10th (1982)

Guard dogs and gas exploders have been successfully used in North Dakota to protect sheep from coyote (Canis latrans) depredation since the mid-1970s. They have been used in addition to other lethal and nonlethal control tools. The U.S. Fish and Wildlife Service gathered information from field testing and landowner interviews to measure their effectiveness. Guard dogs reduced the rate of depredation by 93 percent on the 36 ranches surveyed. Gas exploders deterred coyotes from depredating on 30 ranches an average of 31 days during the 1980 and 1981 grazing seasons. An increasing number of sheep producers are using these control …

The Use Of Fences For Predator Damage Control, Dale A. Wade

Vertebrate Pest Conference Proceedings: 10th (1982)

The development of exclusion fencing has been extensive in Australia in attempts to reduce losses of crops and livestock to rabbits (Oryctolagus cuniculus), dingos (Canis familiaris Var. dingo) and other species. Restrictions on other damage control methods have led to increased efforts in the United States to utilize such fences for protection of crops and livestock from dogs (Canis familiaris), coyotes (Canis latrans) and other species. Electric fences have occasionally been used to protect apiaries from black bears (Ursus americanus) and to protect some wildlife species from carnivores. Varied fence types include conventional net-wire or combinations of net and barbed …

The Future Of Woodenboat Shipyards, Thomas H. Wolstenholme

Marine Affairs Theses and Major Papers

It has been said that wooden boats are a thing of the past. They are now a piece of art which is admired by most and owned by few. This research examines three areas of concern to the traditional wooden boatyard owner- the social demand for his services, the economics of purchase and operation and the ever-increasing legal regulations and requirements. The availability of new materials (i.e. fiberglass) and the tremendous marketing campaign that accompanied its arrival led to a major change in the construction of recreational boats beginning in the 1950's. However,with spiralling costs of petroleum, and thus its …

Buried Bedrock Topography Of The Cannon River System Around Northfield, Minnesota, Timothy D. Vick, Clinton A. Cowan, Daniel J. Packer

Journal of the Minnesota Academy of Science

A geophysical survey in the area of Northfield, Minnesota, involving electrical earth resistivity profiling and seismic refraction soundings, showed sizeable buried river channels in the bedrock in the Cannon River Valley which greatly increase in size downstream of Northfield. The channels upstream from the Northfield appear to be continuous and connect with the large buried channel between Northfield and Cannon Falls. The major buried valley deviates from the modern course of the Cannon River within the City of Northfield, but appears to follow elsewhere.

Vessel Traffic Systems, William D. Lynch

Marine Affairs Theses and Major Papers

This paper will examine the historical impetus for Vessel Traffic System (VTS) development in the United States. Cost benefit techniques utilized to establish the VTS requirements are discussed and the data base upon which the analysis is conducted is critiqued. General Accounting Office criticism of the Coast Guard's VTS development process are analyzed. Finally VTS is examined as a single component in the improvement of port logistics, which must be arrayed against other alternatives to make the most effective use of scarce resources. This final element is discussed with respect to the Federal government's attempt to recover clearly allocatable costs …

Probabilistic Simulations, Nicholas J. Pippenger

All HMC Faculty Publications and Research

The results of this paper concern the question of how fast machines with one type of storage media can simulate machines with a different type of storage media. Most work on this question has focused on the question of how fast one deterministic machine can simulate another. In this paper we shall look at the question of how fast a probabilistic machine can simulate another. This approach should be of interest in its own right, in view of the great attention that probabilistic algorithms have recently attracted.

Masters Theses

The surface polysaccharides of Rhizobium are implicated in the symbiotic process. The composition of the surface polysaccharides from two strains of Rhizobium japonicum, I110 ARS and 61A76 str, have been compared. Five polysaccharide fractions are obtained from the I110 ARS strain. They are the EPS (extracellular polysaccharide), CPS-1 and CPS-2 (capsular polysaccharide fractions), LPS (lipopolysaccharide) and Phe (polysaccharide found in the phenol layer from the phenol/water extraction). These polysaccharide fractions have identical sugar compositions. Four polysaccharide fractions are obtained from the 61A76 str strain. These are the EPS, CPS-1, SmPS (small molecular weight polysaccharide), and Phe. Each of these …

Permeability, Underpressures, And Convection In The Oceanic Crust Near The Costa Rica Rift, Eastern Equatorial Pacific, Roger N. Anderson, Mark D. Zoback

United States Geological Survey: Staff Publications

In situ permeability and pore pressures were measured 200 m deep beneath the top of the oceanic crust at DSDP site 504B. These measurements have relevance for the transition from convective to conductive heat flow on the south flank of the Costa Rica Rift. Conventional 'slug' and constant rate injection tests were made below a hydraulic packer set at various depths in the hole. The packer was first set in a massive flow unit 37 m below the sediment-basement interface. The bulk permeability of the 172.5m of pillow basalts and basaltic flows below the packer was found to be about …

The Interaction Of R. Leguminosarum 128c53 With Pea Root Proteins And A Comparison Of The Surface Polysaccharide With A Mutant Defective In Nodulation, Ru-Po Lee

Masters Theses

The Rhizobium extracellular polysaccharides (EPS) and lipopolysaccharides (LPS) are implicated in the symbiotic process. The interaction between host root protein fractions and symbiont EPS-polyacrylamide affinity support has been investigated. Ten percent root protein fractions had been observed to bind to the affinity support. The compositions of the polysaccharides from the parent R. leguminosarum and its Exo^-1 mutant have also been compared. The Exo^-1 mutant produces diminished amount of EPS and does not nodulate the host pea roots. Five kinds of polysaccharides from the parent were obtained: EPS, capsule polysaccharides (CPS I) washed from the bacteria with saline solution, …

This thesis has developed and tested procedures for siting 900 MWe coal fired thermoelectric generation plants. The procedures developed here permit the placement of these facilities within the existing legal regime, with a minimum of adverse ecological and socioeconomic impact. The process has been designed to consider the entire Island of Puerto Rico for the suitability of siting a 900 MWe coal fired facility. This is accomplished through the …

Catalytic Oxidation Of Sulfur Dioxide In Wastewater, Ernest J. Upton, V. Dean Adams

Reports

Sulfur dioxide has been shown to be an effective wastewater disinfectant. The aqueous sulfur dioxide creates and oxygen demand in the effulent which must be removed prior to discharge. Oxidation to sulfate is one means of accomplishing this task. Experiments were carried out to determine the effectiveness of transition metals and activated carbon as catalysts for the oxidation of S+IV species in wastewater. Both the metals and carbon are known catalysis, but what inhibitory effect the wastewater might have was unknown. Effectiveness was defined as a combination of catalyst life, effluent quality, and cost. Tradition metals were eliminated as potential …

Evaluation Of Microcosms For Determining The Fate And Effect Of Benz(A)Anthracene In Aquatic Systems, Judith G. Dickson, V. Dean Adams, Dennis B. George

Reports

Small scale, three-phase microcosms were used to study the aquatic fate and effect of a polycyclic aromatic hydrocarbon (PAH), benz(a)anthracene. This compound was chosen as a model for carcinogenic PAH because it is a typical constituent of petro-chemical effluents and has middle-of-the-range physical and chamical characteristics. In a series of experiments, techniques were established for monitoring the behavior and for assessing the biological response to the pollutant. Results indicate taht benz(a)anthracene has no acute effect on aquatic organisms as indicated by the parameters used to measure community structure and function (gas productivity, nutrient utilization, biomass accumulation, and species composition). Gas …

Interfacial Electrochemistry Of Cytochrome C And Myoglobin, Edmond F. Bowden

Theses and Dissertations

The interfacial electrochemistry of horse heart cytochrome c was studied at metal and metal oxide electrodes. Sperm whale myoglobin reactions at metal oxide and surface modified electrodes were also investigated. Emphasis was on the measurement and mechanistic interpretation of the heterogeneous electron transfer kinetic parameters for these electrode reactions.

The motivation for this study stems from the fact that some electron transfer proteins, e.g., cytochrome c, transfer electrons heterogeneously in physiological systems. Specific electrodes may, therefore, serve as suitable models for physiological surfaces. Electrode and membrane interfaces are both electrically charged and both have oriented hydration water layers.

The Influence Of Salinity On Larval Development And Population Dynamics Of Anopheles Merus Dönitz (Diptera: Culicidae), F. W. Mosha, C. M. Mutero

All Peer-Reviewed Publications

Variations in density of adults of Anopheles merus Dön. in Jimbo Village on the Kenya Coast were found to be correlated both with rainfall and with salinity at their breeding sites. Densities started to increase at the beginning of the rains when several breeding sites were formed. This was followed by a decline in numbers resulting mainly from the decrease in salinity in the semi-permanent breeding sites. A second rise occurred after the end of the rains, corresponding with an increase in salinity in the semi-permanent breeding sites due to evaporation. Peak density coincided with salinities of 30–50% sea water …
