Benthic Resting Cysts Of Gonyaulax Monilata Howell And Their Relationship To Red Tides In The Indian River, Florida, Kevin C. Owen, Dean R. Norris

Ocean Engineering and Marine Sciences Faculty Publications

Gonyaulax monilata cysts were found in the sediments from 13 of 37 stations sampled in the Indian River, Florida. The distribution of cysts appears to be the result of 2 unrelated phenomena. In areas where blooms have occurred in the past, the lack of circulation in the lagoon allows the cysts to accumulate. South of Turkey Creek, cysts are found associated with shellfish beds where no blooms have been reported. It is suggested these cysts have been introduced into shellfish regions with oysters which are annually rafted from areas where G. monilata blooms occur. Blooms of this toxic dinoflagellate can …

Benthic Testacida (Rhizopoda, Protozoa) Of Lake Washington, Brevard County, Florida, Haydee Lena

Ocean Engineering and Marine Sciences Faculty Publications

Benthic Testacida from sediments of Lake Washington were studied. The Testacida were extracted using standard foraminiferologic techniques. The determined taxa were photographed using scanning electron microscopy. Twenty-one taxa were found. The majority were cosmopolitan and the most abundant were Difflugia pyriformis and Centropyxis compressa. The Testacida guild was similar to that previously studied in other American and European lakes. However, the type and size of the species were different from those found in soil and mosses.

The Fayum Primate Forest Revisited, Thomas M. Bown, Mary Kraus, Scott Wing, John Fleagle, Bruce H. Tiffney, Elwyn Simons, Carl F. Vondra

United States Geological Survey: Staff Publications

In Oligocene times, the Fayum area of northern Egypt was a subtropical to tropical lowland coastal plain with damp soils and seasonal rainfall that supported an abundance and variety of vegetation, including lianes (large vines), tall trees, and possibly mangroves, and a large and varied vertebrate fauna. The Oligocene marine strandline was close by and principal Jebel Qatrani Formation streams were probably brackish several kilometers inland due to tidal incursions. Sediments of the Jebel Qatrani Formation were deposited by several large meandering streams, associated with minor but sometimes extensive flood basin ponds. These rocks provide no evidence for the former …

Analysis Of Petroleum Source Rocks Of The Bakken Formation (Devonian And Mississippian) In North Dakota, Rick L. Webster

Theses and Dissertations

The Bakken Formation of North Dakota consists of upper and lower, black, organic-rich shales separated by a calcareous siltstone middle member. The formation is a relatively thin unit (maximum thickness of 145 feet) with the lower shale .attaining a maximum thickness of 50 feet and the upper shale a maximum thickness of 23 feet. The shales are hard, siliceous, pyritic, fissile, and noncalcareous. They contain abundant conodonts and tasmanites and have planar laminations accented by pyrite. The upper and lower shales were apparently deposited in an offshore, marine, anoxic environment where anoxic conditions may have been caused by silling of …

Evaluation Of A Power Plant Reservoir As A Holding Area For Paddlefish Brood Stock, Terry L. Margenau

Electronic Theses and Dissertations

Twenty paddlefish (Polyodon spathula) released into the Big Stone Power Plant boiler make-up reservoir were monitored to determine growth, condition, and food habits. In addition, fish and zooplankton populations were sampled and chemical and physical parameters measured to determine the potential of the reservoir as a holding area for paddlefish brood stock. Paddlefish captured during the first year after their release into the boiler make-up reservoir averaged 2.2 kg body weight increases and 59 mm eye-fork length increases. Condition factors of captured paddlefish also increased during this period from 1.26 to 1.49. Paddlefish food in the reservoir consisted almost entirely …

A Spectroscopic Study Of Intramicellar Environment With Merocyanine Dye Probes, Elise Jane Daggs

University of the Pacific Theses and Dissertations

The effects of micelle forming surfactants hexadecyltrimethylammonium bromide, sodium dodecyl sulfate and igepal CA~6JO on the visible spectra of merocyanine dyes of the form 1-alkyl-4-[(3', 5'-alkyl oxocyclohexadienylidene)ethylidene]- 1,4-dihydropyridine were studied. In all cases the visible spectrum shifted to the red when the dye was incorporated into the micelles. The magnitude of the shifts was found to be dependent on the substituted groups and the positioning of the chromophore of the dye in the micelle aggregates. The shifts indicate a highly hydrated environment about the surfactant head groups and an environment equivalent to that of pure ethanol solvent at some undetermined …

A Comparison Of The Surface Polysaccharides Of Rhizobium Trifolii Su843 With Its Genetically Altered Mutant, 8002, Which Is Defective At Root Hair Curling (Hac-), Elroy Alfredo Turnbull

Masters Theses

Bacteria of the genus Rhizobium are capable of forming a complex nitrogen fixing (fix⁺) symbiotic association with leguminous plants. The surface polysaccharides are believed to be essential in the symbiotic process. The surface polysaccharides of a genetically altered Rhizobium trifolii mutant, 8002--which does not cause root hair curling (HAC^-), forms no nodules (Nod^-) nor fixes nitrogen (Fix^-)--is compared with its parent, SU843, which causes root hair curling (HAC⁺), forms nodules (Nod⁺), and fixes nitrogen (Fix⁺). Three types of surface polysaccharides--extracellular polysaccharide(s) (EPS), capsular polysaccharide(s) (CPS), and …

A Methodology For Siting Coal Fired Thermoelectric Generating Facilities In Puerto Rico, David J. Mcmahon Ii

Marine Affairs Theses and Major Papers

In the past, energy facilities on the Island of Puerto Rico have not been located in the best practicable sites. This is attributable to the absence of mandatory site selection procedures. 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 …

Extensions, Generalizations, Characterizations And Testing For Independence Through Infinite Divisibility, Edward Joul Danial

Doctoral Dissertations

This dissertation investigates various related topics around the exciting concept: "Infinite Divisibility." First, two intricate distributions, namely, the univariate generalized Waring and the hyper-Poisson are proved to be infinitely and noninfinitely divisible, respectively. Analysis and computer approaches are employed. This itself extends the use of some results introduced by Katti, Steutel and Warde. Secondly, generalizations to Warde, Katti and Steutel's sufficient conditions and related results are achieved. Then, numerical application is presented. Thirdly, characterizations through infinite and finite divisibility are obtained. The Poisson, negative binomial, geometric, Bernoulli and uniform c haracterizations in terms of infinite divisibility are deduced. Some of …

Mechanism Of Polypeptide Chain Initiation In Eukaryotes And Its Control By Phosphorylation Of The Alpha Subunit Of Initiation Factor 2., John Siekierka, Ljubica Mauser, Severo Ochoa

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Earlier, we isolated eukaryotic initiation factor 2 (eIF-2)-stimulating protein (SP) as a homogeneous complex with eIF-2 (eIF-2-SP) and showed that, in the presence of Mg2+, eIF-2-SP promotes formation of a ternary complex with GTP and eukaryotic initiator methionyl tRNA (Met-tRNAi) (eIF-2-GTP-Met-tRNAi) catalytically. We now show that SP-bound eIF-2 exchanges with eIF-2 (eIF-2 exchange). Furthermore, in the presence of Mg2+, eIF-2-SP catalyzes the exchange of eIF-2-bound [3H]GDP with unlabeled GDP or GTP (GDP exchange) and the release of [3H]GDP when the ternary complex is formed from eIF-2-[3H]GDP, GTP, and [35S]Met-tRNAi. All these reactions are blocked by alpha-subunit, but not by beta-subunit, …

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.

Observations On The Biology Of Cave Planarians Of The United States, Jerry H. Carpenter

International Journal of Speleology

Observations are made on the biology of several species of cave planarians (mostly of the family Kenkiidae) collected alive from over 50 caves in 14 states. Most of these species were maintained in laboratory cultures at 12°C±3°C. Food eaten was extremely variable. Functions of the anterior adhesive organ included food capture, locomotion, defence against predators, and probably chemoreception, mechanoreception, and as a holdfast in strong currents. Predators probably consist of fishes, crayfishes, and salamanders. Sporozoan and ciliated parasites were found occasionally. Cocoons were found in winter, spring, and summer; they hatched in about 3 months and contained 2 to 17 …

Paramexiweckelia, A New Genus Of Subterranean Amphipod Crustacean (Hadziidae) From Northern Mexico, John R. Holsinger

International Journal of Speleology

Paramexiweckelia, new genus, is described from a groundwater outlet in Cohauila, Mexico. The type-species, by monotypy, is Mexiweckelia particeps Holsinger. Based on the number of its plesiomorphic (ancestral) characters, this genus is the most primitive member of the family Hadziidae from the North American mainland.

A Contribution To The Knowledge Of The Invertebrate Cave Faunas Of Venezuela: Invertebrate Faunas Of Tropical American Caves, Part 4, Stewart B. Peck

International Journal of Speleology

The invertebrate faunas of four caves in northern Venezuela were studied. Three were dry and one was a wet cave; but guano provided the base of the food chain in all four caves. The faunas in each were strikingly different. Of 24 non-accidental species of arthropods, all were judged to be troglophiles. All were scavengers except for 5 predators, one ectoparasite, and one parasitoid.

Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard (Crangonyctidae) Living In Different Habitats Ii. Population Distribution, Gary W. Dickson

International Journal of Speleology

Population densities and factors affecting the distribution of the troglobitic (i.e., obligatory cavernicole) amphipod Crangonyx antennatus were examined in two distinct aquatic habitats. Observations were made seasonally for one year in six Lee Co., Virginia (U.S.A.) caves, three with mud-bottom pools and three with gravel-bottom streams. Pool habitats were found to contain greater C. antennatus densities than stream habitats, while the highest seasonal densities were recorded in August. Availability of food is considered to be the major factor allowing these increased population densities. The population distribution of C. antennatus was not found to be related to current velocity, water depth, …

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 …

Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson

Marine Affairs Theses and Major Papers

Until the establishment of the Fishery Conservation and Management Act of 1976 (FCMA), fish outside the United States' twelve mile fishery zone were, according to international law, common property and belonged to the nation or individual that caught them. This common property law was based on the concept that fish resources were so large that no amount of fishing would interfere with the right of others to catch fish. Modern technology, however, has created equipment that enabled foreign and domestic fishermen to over-fish the resource. A reduced domestic catch led coastal fishermen to support a bill that unilaterally extended the …

The Systematics And Biology Of The Genus Zapus (Mammalia, Rodentia, Zapodidae), Gwilym S. Jones

All-Inclusive List of Electronic Theses and Dissertations

This study was undertaken to determine specific and intraspecific relationships within the genus Zapus (Mammalia, Rodentia, Zapodidae). Subspecies are based on the biological subspecies concept where the subspecies is an evolutionary step between a population and species. Approximately 20,000 Recent specimens and representatives of fossil taxa were examined. Cranial and postcranial characteristics, colors, and when available bacula, sperms and karyotypes were incorporated into the morphological analyses. In addition, published biological data were summarized and analyzed for evidence of primary and secondary isolating mechanisms. Supplemental data were acquired during collection of 450 specimens in midwestern and western United States, western Canada, …

Keynote Address - Wildlife Damage Control And The Cooperative Extension Services, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

Since the establishment of the Extension Service within the United States Department of Agriculture in 1914, in accordance with the mandate of the Smith-Lever Act, Extension personnel have recognized the need and responsibility to provide educational programs to assist clientele both rural and urban. These programs from the "grass roots" level to the Federal level are based on the "long established premise that assisting people with factual, effective and practical educational programs to help them solve problems, evaluate alternatives and make objective decisions, would provide these people with information that would enable them to help themselves. Wildlife damage control was …

Efficacy And Costs Of Four Rodenticides For Controlling Columbian Ground Squirrels In Western Montana, Steven W. Albert, C. Raymond Record

Great Plains Wildlife Damage Control Workshop Proceedings

Efficacy and costs of four rodenticides for the control of Columbian ground squirrels were compared in western Montana. Reductions in surface ground squirrel activity and costs per 100 burrows treated for the various treatments were: 1080 oat groats 99.6%-$3.11, gas cartridges 72.2%-$26.57, strychnine oats 64.2%-$3.06, zinc phosphide cabbage 60.9%-$8.48, zinc phosphide oats 41.3%-$3.15, and strychnine cabbage 14.4%-$9.58. Surface deaths associated with 1080 amounted to 2.35 ground squirrels per 100 burrows treated. Above ground death rates for the remaining treatments were negligible or nonexistent for both target and non-target species. One white-footed deer mouse was found dead on the strychnine cabbage …

Criteria For Pesticide Registration, John R. Beck, William B. Jackson

Great Plains Wildlife Damage Control Workshop Proceedings

Satisfactory criteria for registration of vertebrate pesticides, other than for commensal rodents, are largely lacking. Even those that are available have not made their way fully through the bureaucratic processes of EPA. Recognizing the difficulty of standardizing pesticide registration, EPA in 1973 requested that the American Society for Testing and Materials (ASTM) consider establishing a committee on pesticides for the purpose of writing consensus standards, guidelines, and practice statements. The resulting committee of more than 400 biological scientists and chemists from academia, industry, and regulatory agencies has prepared standards on many phylogenetic areas.

Urban Vertebrate Pest Management: A Practical Approach, Patricia A. Chamberlain, Milton Caroline, William A. Wright

Great Plains Wildlife Damage Control Workshop Proceedings

Urban vertebrate pest management is influenced by a variety of factors. Public perceptions of wildlife limit control specialists in their methods of operation. Population density, costs of operation and timing of control are considered. Suggestions are made for operational mode, methods, baits, traps and disposal. Two new trapping concepts are described and experimental data on attractants are given. Computer-summarized data on urban wild life conflicts from one state (Texas) show that most complaints can be handled by extension methods supplemented with direct control by the public and wild life damage control specialists.

Animal Damage Control - Now And In The Future, James F. Gillett

Great Plains Wildlife Damage Control Workshop Proceedings

I am pleased to have the opportunity to speak to you today on behalf of the Department of the Interior's Fish and Wildlife Service. I believe animal damage control is an element of a comprehensive wild life management program. It deals with population dynamics, mortality factors, and other management considerations. It is one of a variety of challenges faced by all wildlife managers regardless of whether they are dealing with big game, waterfowl, or even endangered species. Some question the role of, or need for, intensive management of wildlife populations in favor of a "let nature take its course" approach. …
