Distribution Of Bats In The Delta Region Of Northeastern Arkansas, James E. Gardner, V. Rick Mcdaniel
Distribution Of Bats In The Delta Region Of Northeastern Arkansas, James E. Gardner, V. Rick Mcdaniel
Journal of the Arkansas Academy of Science
Eight taxa of bats are reported from seven counties in northeastern Arkansas. Localities, natural history notes, sex, age and reproductive condition are reported for most species. New records are combined with previously existing ones to reveal a greater distribution of chiroptera for the state

Fishes Of The Mountain Province Section Of The Ouachita River, John L. Harris, Neil H. Douglas
Journal of the Arkansas Academy of Science
A survey of the fishes of the mountain province section of the Ouachita River from the headwaters to Remmel Dam using field collections, literature records, and museum collections showed the ichthyofauna to be made up of 80 species representing 16 families. Fourteen species not previously reported from the mountain province section of the river were collected in this survey. These species include Ichthyomyzon gagei, Nocomis asper, Notropis ortenburgeri, N. rubellus, Pimephales promelas, Moxostoma carinatum, Noturus taylori, Fundulus notatus, Lepomis humilis, Etheostoma histrio, E. proeliare, Percina maculata, P. nasuta, and P. uranidea. The Nocomis specimens were the first collected from the …

The Reproductive Cycle Of Microtus Ochrogaster In Eastern Kansas, Robert K. Rose, Michael S. Gaines
The Reproductive Cycle Of Microtus Ochrogaster In Eastern Kansas, Robert K. Rose, Michael S. Gaines
Biological Sciences Faculty Publications
About 800 Microtus ochrogaster were live—trapped at biweekly intervals from May 1971 through March 1973 in 3 grassland study areas in eastern Kansas, USA. Details of reproduction were determined by autopsy. Population density increased through the first winter, reached a peak in April 1972, then declined sharply during that summer and beyond. Body length, but not body mass, tended to be positively related to density. Both sexes matured at about the same weight; development was somewhat prolonged during the winter months, especially in the winter preceding the population peak. Pregnancy rates were high, approaching maximal iteroparity, throughout the study, with …
Interactions In Lambdoid Bacteriophage Populations, Bruce Edward Mitchell
Interactions In Lambdoid Bacteriophage Populations, Bruce Edward Mitchell
Masters Theses
The lambdoid bacteriophages are ideal subjects for the study of populational interactions at the molecular level because they do not mutually exclude one another in mixed infection of the same host cell. Previous work done in this laboratory using the lambdoid phage pairs λ-434 hy mi and λ-∅80 have demonstrated a density-dependent reduction in progeny yield per infected cell (burst size) as a function of increasing multiplicity of infection (m.o.i.). The λ cI gene which codes for the repress or molecule has been demonstrated to be the cause of the interaction in the λ-434 hy mi phage pair. …
