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.

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 …

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), …

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 …

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.
