The Wavelength Dependence Of Ultraviolet Enhanced Reactivation In A Mammalian Cell-Virus System, Leslie C. James

Masters Theses & Specialist Projects

The effect of ultraviolet (UV) radiation in the wavelength region 230 nm to 302 nm on the ability of an irradiated mammalian cell to reactivate UV-irradiated mammalian virus was tests. An action spectrum for radiation enhanced reactivation (RER) Is presented. The shape of the action spectrum points to a combined nucleic acid protein target for UV radiation effects on this cellular parameter. An analysis of the results of others involving the biochemical and photobiological events involved in the RER does not allow the identification of the macromolecule which is the major contributor to this effect. Studies involving an analogous phenomenon …

Differential Clotting Responses Of Rabbits To Injections Of Homogenates From Wild-Type And Tumorous-Head Drosophila Melanogaster, Alfred B. Cox

Retrospective Theses and Dissertations

Two groups of New Zealand white rabbits were injected with homogenates from Tumorous-head (Tuh) and Wild-type (WT) Drosophila melanogaster. A third group was used as a saline injected control. Blood collected in both acute and chronic studies was subjected to various hematological and post mortem studies. The Tuh injected group showed a five-fold increase in thrombocytes (blood platelets) over the controls and four-fold increase over the wild-type group. Reduced clotting times were noted from acute to chronic studies in both tumorous and wild-type studies; however, the magnitude of change between the two groups was insignificant. Investigations involving electrophoretic banding patterns, …

Radiotelemetry Of Heart Rates From Free-Ranging Gulls, J. W. Kanwisher, Timothy C. Williams , '64, J. M. Teal, K. O. Lawson

Biology Faculty Works

A lightweight radiotelemetry system with a range of 80 km was used to monitor heart rate from free-ranging Herring Gulls on flights of up to 20 km. Heart rate varied from 130 beats/min in a resting bird to 625 beats/min for sustained flight. Soaring birds showed rates similar to those of birds sitting quietly on the ground. Simultaneous records of telemetered heart rate and intraspecific conflict on the nesting island revealed that cardiac acceleration preceded overt visual communication. Intensely aggressive behavior was accompanied by heart rates approaching those of sustained flight. Heart rate as a measure of metabolic cost indicates …

Spirocamallanus Cricotus Sp. N. And S. Halitrophus Sp. N. (Nematoda: Camallanidea) From Fishes In The Northern Gulf Of Mexico, Alan C. Fusco, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Spirocamallanus cricotus sp. n. (= S. pereirai, in part) and S. halitrophus sp. n. are described from marine fishes of the northern Gull of Mexico. Spirocamallanus cricotus has a ledge anterior to the basal ring in the buccal capsule, similar spicules with a ratio of 1:1.4 to 2.1, 3 pre- and 5 postcloacal papillae, and 8 rectal glands in the female; S. halitrophus lacks the ledge and possesses dissimilar spicules with a ratio of 1:1.3 to 1.8, 3 pre- and 6 postcloacal papillae, and 4 rectal glands in the female.

The Opossum (Didelphis Virginiana) As A Host For Sarcocystis Debonei From Cowbirds (Molothrus Ater) And Grackles (Cassidix Mexicanus, Quiscalus Quiscula), Donald Duszynski, Edith D. Box

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sarcocystis-infected muscles from ducks, cowbirds, and grackles were fed to cats, opossums, rats, and a dog. Only the opossum (Didelphis virginiana) was a suitable definitive host. All opossums that were fed Sarcocystis-infected cowbirds (Molothrus ater) and grackles (Cassidix mexicanus and Quiscalus quiscula) passed sporocysts in their feces. Opossums that ate the cowbirds had prepatent periods of 5 and 10 days and remained patent for at least 105 days. Opossums that ate the grackles became patent on day 10 after the infective meal and remained patent for over 90 (Quiscalus) and …

Vegetational Communities On An Abandoned Farm In Van Buren County, Michigan, Larry G. Visser

Masters Theses

Introduction

Several studies have been made of xeric forests in southern Michigan which have developed through secondary succession following the cutting of the presettlement vegetation. Brewer et al. (1973) described such an area in Allegan County, Michigan which was dominated by presettlement pine and is now dominated by oak. The oak forests of the Harvey Ott Preserve in Calhoun County, Michigan have been described by Catana (1967). Studies of the oak forests in the Haven Hill area in southeastern Michigan have been made by Thompson (1953). In addition to these studies of xeric forests in southern Michigan, extensive studies of …

The Photosynthetic Action Spectra Of The Phytoplankton And Their Role In Governing Spatial And Temporal Distribution: A Numerical Modeling Approach, William Morrow Willis

OES Theses and Dissertations

In the present study a numerical modeling approach is employed to examine the role of division spedific differences in photosynthetic action spectra in governing the relative size of diatom and dinoflagellate carbon synthesis along various marine light regime gradients. A radiative transfer model taking into account both Rayleigh and Mie atmospheric optical properties is employed to define the light regime incident on the sea surface. The hydrospheric light regime is defined by an exponential decay model with a correction for diffuse back scatter. Taken together, the atmospheric and hydrospheric models define the spectral composition and intensity of light in the …

Experiments In Attempted Interspecific And Interpopulational Hybridzation Of Grass Shrimp Of The Genus Palaemonetes (Caridea Palaemonidae), Mark Andrew Boston

OES Theses and Dissertations

The present study investigates the interfertility of Palaemonetes populations, Interspecific crosses were attempted between representatives of sympatric :populations of P. pugio, P. vulgaris, and P. intermedius, Intraspecific crosses were undertaken between geographically separated :populations of P. pugio. Laboratory conditions of 25°c, 25°/oo, and 14.5 hour photoperiod per day were maintained for all breeding attempts, Under these conditions interspecific hybridization of Palaemonetes pugio and P. vulgaris was not feasible. P. intermedius could not be hybridized with P. pugio and P. vulgaris. At 40 days of age P. pugio juveniles were significantly larger than P. vulgaris juveniles of …

Herbaceous Production In Burned-Cut Burned-Uncut And Control Areas Of A Chamaecyparis Thyoides (L.) Bsp (Cupressaceae) Stand In The Great Dismal Swamp, Caroline Elisabeth Mckinley

Biological Sciences Theses & Dissertations

The herbaceous layer of an Atlantic white cedar (Chamaecyparis thyoides) stand in the Great Dismal Swamp was sampled to estimate the productivity of two burned areas and a control area. The herbaceous vegetation was sampled along three transects utilizing the harvest method and productivity values were estimated using peak biomass values for each individual species. The burned-cut area had the highest productivity (3623 kg ha^-l yr^-1) and was characterized by species of the Asteraceae, Poaceae, and Cyperaceae. The burned-uncut area had a productivity value of 1636 kg ha^-1 yr^-1 with similar species of the Asteraceae …

Bats From Southern Haiti, David Klingener, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A collection of 450 specimens of bats from the Departement du Sud, Haiti, is described. Fifteen of the 17 species previously recorded from Hispaniola are represented, and Noctilio leporinus is reported from Haiti for the first time. Reproductive information for the months of January, May, June, August, and December is presented. Macrotus waterhousii is seasonally monoestrous, as on the mainland. The two species of stenodennines, Artibeus jamaicensis and Phyllops hailiensis, do not show bimodal seasonal polyestry as do stenodermines in Central America. Monophyllus redmani and the phyllonycterines may be seasonally monoestrous. Differences in reproductive biology between Haitian bats and …

Studies On Uveitis Part Ii: Hypotheses With Case Reports, Philip C. Hessburg

Henry Ford Hospital Medical Journal

A number of patients with and without uveitis are used to show that this study of aqueous microbiology suggests the following hypotheses: 1. Routine techniques currently used in most microbiology laboratories overlook classical and variant bacteria which might be isolated from clinical specimens with improved microbiological techniques. 2. Bacterial forms may be present in other ocular tissue when not present in the aqueous. 3. Polymicrobial infections probably occur rather frequently, especially in chronic or subacute inflammatory states. 4. Alterations in various host factors may subject some persons to a greater incidence of inflammatory episodes including uveitis. 5. Antibiotics used in …

Quantitative Analyses Of The Ontogeny Of Predatory Behaviour In Coyotes, Canis Latrans, Louis E. Vincent, Marc Bekoff

Ethology Collection

Four infant coyotes (Canis latrans) were studied in order to describe quantitatively the development of predatory behaviour. Our results indicated that prior play and agonistic experience had virtually no effect on later predatory success. Also, there was no relationship between an individual's social rank and its prey-killing ability. Latency to kill was shortened when animals were tested in, pair and hunger level was not related to latency to kill. The results are discussed with respect to current 'functionalist' theories of play behaviour and Leyhausen's concept of the relative hierarchy of moods. The practice theory of play should be reconsidered in …

Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox

Journal of the Department of Agriculture, Western Australia, Series 4

Soil and plant analysis can be used to identify problems in soils, diagnose nutrient deficiencies and as a guide to fertiliser usage.

Soil testing is particularily useful where large amounts of phosphorus and potassium are leached or removed from the paddock in hay or silage.

Actual rates of fertiliser can only be recommended from soil testing and only in conjunction with additional biological and economic information.
