Range And Optimum Growth Concentrations Of Phosphate And Nitrate For Chlamydomonas Reinhardtii, Thomas E. Hill

Masters Theses

A study was conducted on the alga Chlamydomonas reinhardtii to determine the range and optimum growth concentrations of phosphate and nitrate. There are only a few species of algae for which this type of data is known. Inorganic nutritional data is basic to the understanding of the complexities of phytoplankton ecology and eutrophication.

The "plus" strain of this heterothallic alga was cultured in a TRIS-buffered inorganic medium with various concentrations of sodium phosphate and potassium nitrate and adjusted to a pH of 7.4. The axenic cultures were evaluated at the end of 6 days with a spectrophotometer, at a wavelength …

Voluntary Control Of Gsr Using Continuous Visual Display And Simultaneous Changes In Other Autonomic Functions, Laurence E. Boyce

Masters Theses

Using 28 male undergraduate university students provided with continuous oscilloscope display of basal skin resistance, this study investigated voluntary control of the GSR and concurrent changes in respiration. It was found, given feedback, subjects could voluntarily raise or lower their GSR. Subjects instructed to increase their GSR (N-14) could do so within the first trial session. However, subjects instructed to decrease their GSR (N-14) required additional practice. With less than 20 minutes of practice all subjects were able to reach a criterion of 2,500 ohms change from their basal level. Subjects increasing their GSR were found to have a significant …

A Study Of Thoracic Skeletomusculature In Peracarida (Crustacea), Donna R. Gill

Masters Theses

Two species of peracarid malacostracans, a mysid, Neomysis americana, and an oniscid isopod, Trachelipus cf. rathkei, were used to study the skeletomusculature system. Serial sections, whole mounts, and gross dissections were made. Coxal promotors and remotors and basal adductors and abductors were the muscle groups examined.

The promotor and remotor muscles of N. americana were found to be numerous, well developed, taking origin primarily from the dorsal thoracic wall, and extending nearly ventrally to insert in the coxa; the adductor muscle and two abductor muscles are weakly developed. The coxa in T. cf. rathkei is incorporated completely …

Water Quality And Benthos Of A Small East Central Illinois Stream, With A Selected Literature Review, Kenneth Lloyd Brummett

Masters Theses

Polecat Creek is an occasionally intermittent stream which drains approximately 18,368 acres in eastern Coles County, Illinois. It travels 15.2 miles through cropland and a partially wooded valley before it enters the Embarrass River 3 miles upstream from Lake Charleston. The stream ranges from 0.5 foot to 5 feet deep at a normal water level, with an average depth of 16 inches. It averages 12 feet wide, with a range from 4 to 20 feet.

A water quality study with 5 stations along the stream was conducted from January 1971 to July 1971. A qualitative benthos study at the same …

Preliminary Observations On The Effects Of Treflan To Fishes, P. Bradley Latvaitis

Masters Theses

Treflan E.C. is a selective, preemergence, soil incorporated herbicide. Preliminary tests were made to evaluate its effects at concentrations of 0.75, 1.275 and 1.8 p.p.m. on twenty species of fresh water fishes in the laboratory. The herbicide was proven to be a powerful fish toxicant. Centrarchus, Cichlasoma centrarchus, was the most resistant fish tested, while Bluegill, Lepomis macrochirus, was among the least resistant. Treflan E.C. decomposes and degrades rapidly. It was also found to interact with plastics. Further studies are necessary to provide a complete investigation of the effects of Treflan on Fishes.

A Comparison Of Nocturnal Restlessness Of Caged Thrushes And Migration Of Free Thrushes, Charles Goodwin Kjos

Masters Theses

Nocturnal activity (Zugunruhe) of eight caged, radio-tagged thrushes (Hylocichla spp.) was compared by signal analysis with the occurrence of migration in 16 free, radio-tagged thrushes over a 37-night period during the autumn of 1970 in central Illinois. The study was conducted to determine the extent of synchrony of Zugunruhe and migration in these nocturnal migrants in fall. Zugunruhe frequently occurred on nights when there was no migration, but migration occurred only on nights when at least 50 per cent of the caged birds were active. Except for one departure which was atypical in several respects, migration occurred …

Home Range And Movement Of Fox Squirrels In East Central Illinois, Michael D. Sliva

Masters Theses

Home ranges and movements were determined for 11 fox squirrels (Sciurus niger) and analyzed with respect to the distribution of mast trees and den trees on a 12¼ acre wooded plot in east central Illinois. Average home range size for all squirrels was 0.9 acres. The home range of adult squirrels averaged 1.5 acres while juveniles averaged 0.8 acres. Females had larger home ranges (1.4 acres) than males (0.6 acres). The average distance moved within the home range was 360 feet for all squirrels. The average distances moved by adults and juveniles was nearly the same (275-280 feet), …

Operant Conditioning In The Garter Snake (Thamnophis), William A. Schmitz

Masters Theses

Ten garter snakes were tested for runway acquisition, correct turn response in a simple T-maze, or both, for food reinforcement. Seven of seven subjects met criterion for learning to run a 23 inch long alleyway. Mean latency times showed a general decrease over a 23 day period. Five of nine subjects met criterion for learning a correct turn response in a simple T-maze. Subjects mastering the task required from 14-157 trials. One of two subjects met criterion for learning the reverse response of the T-maze exercise, requiring 35 trials. Results are similar to those previously reported for reptiles and other …

The Effects Of The Four Psychological Primary Colors On Gsr, Heart Rate, And Respiration Rate, Keith W. Jacobs

Masters Theses

Measurement of GSR, heart rate, and respiration rate were taken on twenty-four male S's during presentation of four colors (red, yellow, green, blue). Four sequences of color presentations were used based on a 4 by 4 latin square with six subjects receiving each presentation. Significant color effects (p < .05) were found when GSR was used as the measure of activation. The most arousing color was red, followed by green, yellow, and blue, with significant differences in arousal value found between colors. Significant trial effects, disregarding colors, were found in respiration rate. No significant effects on heart rate were found as a function of trials or color. The arousal values of the colors do not support either a linear or U-shaped function of wave length.

Gastro-Intestinal And Abdominal Helminths Of White-Tailed Deer (Odocoileus Virginianus) In Southern Illinois, Thomas W. Cook

Masters Theses

In November and December 1971, forty deer from five southern Illinois counties were examined by necropsy for gastro-intestinal and abdominal helminths. Eight species of gastro-intestinal nematodes were found: Gongylonema pulchrum, Spiculopteroides odocoilei, Ostertagia mossi, Haemonchus contortus, Cooperia sp., Capillaria sp., Trichuris ovis and Oesophagostomum venulosum. Setaria yehi, a filiariad nematode, was found in the abdominal cavity. Moniezia benedeni was the only cestode found. No trematodes were recovered.

The Effects Of Desoxycorticosterone, Hydrocortisone, And Prednisone On Myogenesis In Vitro, Gregory K. Nienaber

Masters Theses

In order to obtain proper muscle development in tissue culture, certain conditions must prevail. There is a delicate balance of factors, and elimination of even one of these factors leads to poor and improper development. Muscle cells grown in the absence of fibroblasts usually fail to differentiate. Therefore, proper development depends upon the presence of two cell types: myoblasts and fibroblasts. Investigators have demonstrated that the fibroblasts are necessary in that they produce collagen which is necessary for proper muscle development. The present study has shown that desoxycorticosterone, hydrocortisone, and prednisone at concentrations of 10, 1, and 0.1 ug/ml of …

Gastro-Intestinal Helminths Of Illinois Bobwhites, Michael Eugene Gordon

Masters Theses

The viscera of 103 bobwhite quail (Colinus virginianus), from east central Illinois counties, were collected during November and December of 1971 and examined for helminth parasites. Two nematodes were identified: Dispharynx nasuta (9.7%) and Ascaridia sp. (7.8%). The rate of infection varied significantly between counties but there was no difference in parasitism of males and females.
