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

Pseudomonas As Causative Agents Of Fluorescence In Anguispira Kochi (Pfeiffer) Mucus, John Michael Baum
Pseudomonas As Causative Agents Of Fluorescence In Anguispira Kochi (Pfeiffer) Mucus, John Michael Baum
Masters Theses
The mucus from land snail specimens of Anguispira kochi collected from Coles and Edgar counties, Illinois, emits a blue fluorescence when exposed to ultra-violet light. Pseudomonas, a genus of bacteria which produces fluorescent pigments, has been isolated from the mucus of these snails. The object of the study was to compare the fluorescence of the mucus from individuals of A. kochi with the fluorescence of the pigments produced on a synthetic medium by pseudomonads isolated from the mucus of these snails. An effort was made to establish that Pseudomonas is the causative agent of fluorescence in the mucus of …

Reproductive Cycle Of The Male Snapping Turtle, Chelydra Serpentina Serpentina (Linné), Harold Edward Benny
Reproductive Cycle Of The Male Snapping Turtle, Chelydra Serpentina Serpentina (Linné), Harold Edward Benny
Masters Theses
Thirty-seven male Chelydra s. serpentina were collected from Illinois, Louisiana, Mississippi, Tennessee, and Wisconsin during months of activity from May, 1969 to June 1971. Carapace length for each specimen was measured, and testes and epididymides were dissected out, weighed, measured, fixed, and preserved in Baker's neutral formalin within seven days of capture. Paraffin sections were stained with hematoxylin and eosin. Frozen sections were stained with Sudan IV.
The spermatogenic cycle was similar to those of other Chelonians and reptiles exhibiting post-nuptial spermatogenesis. In Illinois spermatocytogenesis begins in late March or early April. Meiosis is evident throughout May and early June. …

Studies On The Effects Of Toxic Materials On The Respiration Rate Of Tubificidae, Richard A. Sikora
Studies On The Effects Of Toxic Materials On The Respiration Rate Of Tubificidae, Richard A. Sikora
Masters Theses
A study was made to determine the effect of lead, nickel and pentachlorophenol, at varying pH levels, on the respiration rate of this family of aquatic oligochaetes. Respiration was measured as the ul. of oxygen consumer per mg. of live tissue per hour of exposure.
Worms were found to decrease their rate of respiration in the presence of lead nitrate. This was demonstrated at three pH levels: 6.5, 7.5 and 8.5. It was concluded that this drop was due to the action of lead on the enzymes of the metabolic systems and on the characteristic of lead which stimulates the …
