Epizoic Protozoa Of Planktonic Copepoda And Cladocera From A Small Eutrophic Lake, And Their Possible Use As Indicators Of Organic Water Pollution, Michael Stevens Henebry

Masters Theses

The epizoic protozoa of planktonic copepoda and cladocera from a eutrophic lake (Ashmore Lake, Coles County, Illinois) were studied over a 13-week period in the summer and fall of 1975. All organisms were collected with a 125 micron mesh plankton net. Epizoans (all peritrichs and suctorians) were hosted by three of four species of copepods and four of the ten species of cladocerans. The percentage of total organisms hosting epizoans varied significantly (0.001 alpha level) by month, but averaged 11.6 percent. This high occurrence of epizoans was thought to be related to the highly-eutrophic conditions existing in the lake. If …

Effects Of Intertidal Height And Infestation By Fabia Subquadrata Dana On Glycogen, Lipid And Body Component Indices Of Mytilus Californianus Conrad, Gregory L. Anderson

University of the Pacific Theses and Dissertations

As our knowledge of bivalves has increased, so has information about their parasites. Most studies of bivalve parasites have been devoted to groups infesting commercially important mollusks, notably trematodes and copepods. Another group of bivalve symbionts which has been known since the early nineteenth century is the brachyuran genus Pinnotheres Latreille, 1802 (commonly known as pea crabs). The generic name was given because of the belief that the crabs were predators upon the scallops in which they were most frequently found (Pearce, 1966). However, Stebbing (1893) suggested that instead of acting as predators, the crabs were in fact serving as …

The Effects Of Predation And Sediment Reworking By The Maldanid Polychaete Axiothella Rubrocincta (Johnson) On Benthic Littoral Microalgae Assemblages, Gary Scott Shusta

University of the Pacific Theses and Dissertations

The taxonomic composition of the diatom assemblages inhabiting the substrate on the mudflat, and the effects of a cohabiting deposit-feeding invertebrate on the diatom assemblage structure are the subjects of this paper. While pelagic diatoms have received considerable attention in the literature to date, comparatively little is known about the ecology and distribution of benthic diatoms are known to be cosmopolitan in their distributions (Alee, 1950). These plants have been found to be opportunistic species in that they are quick to respond to relatively small perturbations in physical conditions. It has also been demonstrated that distinct associations of diatoms exist …

Mathematical Equations Describing Chick Performance And Carcass Composition As A Function Of Diet Protein And Energy Levels, Naiyana Nakhata

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous work at Utah State University determined minimum levels of different nutrients that would produce the maximum rate of gain or gain/feed ratio by feeding graded levels of the nutrients. Fitting broken lines to the data from work with one nutrient tended to underestimate the minimum requirement for that nutrient. It appeared that the response was not linear up to the level required to give maximum performance as the "broken line" approach to estimating the requirement assumes. It seemed worthwhile to try to describe the relation between ration level of a nutrient and chick performance by means of a mathematical …

Biochemical Characteristics And Antibiogram Patterns Of Some Gram-Negative Nonfermentors, Donald E. Berkowitz

University of the Pacific Theses and Dissertations

This study was undertaken, chiefly, for the purpose of characterizing biochemically a random sample of non fermentative bacilli obtained from local hospitals and determining the prevalence of Ps. aeruginosa among them. A second objective was to compare the antibiogram patterns obtained in this study with those reported by other investigators, and thirdly to establish a baseline for future comparative studies.

Studies On Uveitis Part I: Aqueous Studies, Philip C. Hessburg

Henry Ford Hospital Medical Journal

Aqueous microbiological and cytological studies were performed on 134 anterior chamber taps done on 118 patients both with and without uveitis. Cell wall defective bacterial forms (CWDF) were recovered from about 40% of these aqueous specimens and classical bacteria were recovered from 12%. A statistically significant difference could not be found between the incidence of bacterial cell wall defective forms in the various anatomical types of uveitis. There were hints from this work that the presence of CWDF In the aqueous was more frequent in younger patients with uveitis, early in the uveitis attack, if there were multiple foci of …

Effect Of Steroids On Patients With Postoperative Bowel Anastomotic Dysfunction, Luis H. Toledo-Pereya, Ignacio Guzman, Earl G. Yonehiro

Henry Ford Hospital Medical Journal

Ten patients who developed anastomotic edema following large or small intestinal anastomosis had a rapid recovery after treatment with dexamethasone. The clinical and radiologic picture of adynamic ileus disappeared rapidly. There were no Immediate or long-term (more than two years) complications or side effects associated with the use of dexamethasone. This preliminary report indicates that dexamethasone may be a beneficial agent In the control of anastomotic edema.

Feeding Biology And Ecological Aspects Of A Cancroid Crab Cancer Oregonensis (Dana) Rathbun (Decapoda, Brachyura), Gary L. Child

Theses and Dissertations

In the San Juan Archipelago, cancer oregonensis (Dana) Rathbun (Fig. 1) is abundant and distributed from the low intertidal zone to -435 m subtidally (Rathbun, 1904). Ricketts and Calvin (1974) refer to c. oregonensis as the most common Cancer species in this area.

The Biology Of Coprinus Radians, Ozonium, Oidium, And Their Interrelationships, Thomas J. Fahey

All-Inclusive List of Electronic Theses and Dissertations

The pleomorphism of Coprinus radians was studied. The three distinct growth forms--sporophore, oidial stage, and ozonium stage--were examined in relation to ultrastructure, morphology and development. Scanning and transmission electron microscopy are correlated with photomicrographs of developmental stages. Development of the oidia and of the sporophore are of particular interest. The multinucleate oidia develop quite differently from oidia as generally described for Basidiomycete imperfect stages. Development of the oidia of this Coprinus is holoblastic and sympodial. The mushroom primordia are differentiated internally into gill, cap, and stipe hyphae while only l-2mm in diameter. At this stage they look superficially like sclerotial …

Morphometric Variation In The Tropical Pocket Gopher (Geomys Tropicalis), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The tropical pocket gopher (Geomys tropicalis). which exhibits no chromosomal or genic variation, was examined for variability at the morphometrical level. Univariate and multivariate analyses were used to determine age, sexual, and geographical variation. Significant differences were found between different age classes and between sexes. The amount of individual variation was comparable with other rodents and did not exhibit the reduced variation expressed at the chromosomal and genic levels, G. tropicalis is considered to be a monotypic species.

The Extrafloral Nectaries Of Ipomoea Carnea (Convolvulaceae), Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

lpomoea carnea (Convolvulaceae) possesses two types of extrafloral nectaries, located on the petiole and on the pedicel. These secrete a complex nectar containing sugars and amino acids. The insects attracted to the extrafloral nectaries are predominantly ants and they are relatively abundant throughout the year. A number of incidents of plant defense as a result of the presence of extrafloral nectary visitors at the extrafloral nectaries of I. carnea were observed and are consistent with the ant-guard theory of the function of extrafloral nectaries.

Herpetomonas Megaseliae And Crithidia Harmosa: Growth On Blood-Agar Plates, Amy Doran Kepel, John J. Janovy Jr.

John J. Janovy, Jr. Publications

A technique for culturing two species of trypanosomatid flagellates on blood-agar plates is described. Herpetomonas megaseliae and Crithidia harmosa were grown as discrete clone colonies on plates prepared in sterile petri dishes with a medium derived from that of Tobie et al. (1950, J. Parasitol. 36: 48-54). Plates were inoculated with 0.01 ml flagellate suspension and the inoculum was spread evenly over the surface of the agar with a sterile glass spreader. Plates were incubated in a high humidity chamber at 25 C and colonies of both species, easily visible to the unaided eye, appeared within 1 week. There was …

Description Of The Larval Development Of Squilla Empusa Say (Crustacea Stomatopoda) With Aspects Of Larval Ecology In Chesapeake Bay, Steven Gaines Morgan

OES Theses and Dissertations

Larvae of Sguilla empusa were collected from the plankton and were reared in the laboratory to describe the pelagic larval development and the postlarval stage. Nine pelagic stages are passed through before the postlarval stage is attained.

The larvae reared for descriptive purposes were subjected to sixteen combinations of temperature and salinity to determine their tolerance to the two parameters. Larvae survived longer and molted more frequently when reared at 25°/oo and 20°C or 25°C, which corresponds to the natural conditions of the Chesapeake Bay when the larvae were collected.
