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
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 …
Utilization Of Heat Sensitivity In Crotalidae, James Cordrey Miller
Utilization Of Heat Sensitivity In Crotalidae, James Cordrey Miller
Masters Theses
Specimens of five genera of snakes (Crotalus, Agkistrodon, Bitis, Epicrates, and Elaphe) were tested for use of thermal cues in food selection. Results indicate that pit vipers (Crotalus and Agkistrodon) and boas (Epicrates) utilize thermal radiation in selection of food. It was also indicated that Crotalus (rattlesnakes) do not invariably show a reflexive strike before food is investigated or ingested.
Capillaria Sp. From Cryptotis Parva, Joseph N'Dong
Capillaria Sp. From Cryptotis Parva, Joseph N'Dong
Masters Theses
Twenty-nine Cryptotis parva were trapped at Lincoln Log Cabin State Park in Coles County Illinois between 22 December 1976 and 31 January 1978. Trapped specimens were necropsied and examined for the presence of helminth parasites. Nematode infections were found to be present in eight (27.2%) of the shrews collected with five (17.2%) of the males and three (10.3%) of the females infected. Three adult female nematodes were recovered from the small intestines of the host specimens, described and identified as the genus Capillaria. No male Capillaria were obtained and therefore species identification was impossible. However, the general appearance of …
Feeding Habits And Behavior Of The Whiptail Lizard Cnemidophorus Tigris On Partida Island, Patrick Alan Malone
Feeding Habits And Behavior Of The Whiptail Lizard Cnemidophorus Tigris On Partida Island, Patrick Alan Malone
Masters Theses
The feeding habits of the whiptail lizard Cnemidophorus tigris were studied from May 25 until July 23, 1977 on the Partida Island in the Gulf of California. Analysis of the stomach contents of 91 lizards revealed that during this period the eggs and young of the least and black petrel are a primary food source while tenebrionid beetles become a major food source after bird products become unavailable.
A Histochemical Study Of Tooth Development In The Chinese Hamster (Cricetulus Griseus), Robert B. Daszkiewicz
A Histochemical Study Of Tooth Development In The Chinese Hamster (Cricetulus Griseus), Robert B. Daszkiewicz
Masters Theses
The normal morphological development of the Chinese hamster (Cricetulus griseus) during the last week of gestation was studied. A review of the literature reveals no distinct study of tooth development in this species. An identical gestation period is found in the mouse (Mus musculus) making direct comparison between the embryos of the same age of the two species feasible. During this investigation, it was found that morphological tooth development in the Chinese hamster lagged behind that of the mouse by about 2 days. On day 14 of gestation in the Chinese hamster, the oral epithelium is …
A Study Of Symbiosis Involving The Fish-Eating Bat (Myotis Vivesi), The Least Petrel (Halocyptera Microsoma), The Black Petrel (Oceanodroma Melania), And The Lizard (Cnemidophorus Tigris), Joel King
Masters Theses
A field study was conducted on Partida Island in the Gulf of Mexico on the dates May 26 through July 26, 1977, inclusive.
Field observations were made of the lizard (Cnemidophorus tigris) preying on eggs and hatchlings of the least petrel (Halocyptena microsoma), and the black petrel (Oceanodroma melania). The petrels roost among rock slides with the fish-eating bat (Myotis vivesi).
In 24 trials of experimental boxes with lizards, bats, and petrels as subjects, 16 trials resulted in aggression of bats to lizards.
A symbiosis is postulated between bats and petrels.
Blood Gases And Certain Energy Metabolite Concentrations In Ammonia Intoxicated Sheep, George E. Romkema
Blood Gases And Certain Energy Metabolite Concentrations In Ammonia Intoxicated Sheep, George E. Romkema
Electronic Theses and Dissertations
The objectives of this study were to measure the changes occurring in certain blood parameters during acute ammonia intoxication. It was hoped that these changes would reflect and thereby provide insight into the effects of acute ammonia intoxication on metabolic processes. Blood pH, p02, and pC02 were measured in order to observe possible metabolic disturbances as reflected in the acid-base balance. Glucose was measured due to its importance as a basic energy source and metabolic intermediate. Volatile fatty acids were measured because they serve as an important energy source in ruminants. Non-esterified fatty acids and triglycerides were …

The Structure And Fate Of Germinal Plasm In The Asiatic Fire-Bellied Frog, Bombina Orientalis (Anura-Discoglossidae), Ted W. Odom
The Structure And Fate Of Germinal Plasm In The Asiatic Fire-Bellied Frog, Bombina Orientalis (Anura-Discoglossidae), Ted W. Odom
Masters Theses
Lehman's polychrome stain was used to follow the fate of germinal plasm in early development of Bombina orientalis embryos. Islets of germinal plasm approximately 6 um in diameter were observed in the vegetal pole region of the 2-cell embryo. By the 4-cell stage, some of these islets had coalesced to form larger ones so that two size classes of islets were present (approximately 7.5 and 19.5 um in diameter).
As cleavage continued to the 16-cell stage, the islets were moved further up the cleavage furrow and were always observed to remain in close association with the cleavage membrane. The islets …
