The Fall And Winter Food Habits Of The Black Bear (Ursus Americanus) In The Great Dismal Swamp Of Virginia, Francis Leonard Daniel

Biological Sciences Theses & Dissertations

A study was conducted on the food habits of the black bear (Ursus americanus) in the Great Dismal Swamp of Virginia. A total of four stomachs and 42 scats were analyzed. Four samples were collected from September and October of 1975, and the remainder of the samples were collected from September 1976 to February 1977. The study was conducted to obtain information vital to the management of this species in the Great Dismal Swamp. Vitis spp. was the primary food item during the fall comprising 43% of the total diet, followed by fruits of Diospyros virginiana and Asimina triloba, each …

Experiments In Attempted Interspecific And Interpopulational Hybridzation Of Grass Shrimp Of The Genus Palaemonetes (Caridea Palaemonidae), Mark Andrew Boston Apr 1978

Experiments In Attempted Interspecific And Interpopulational Hybridzation Of Grass Shrimp Of The Genus Palaemonetes (Caridea Palaemonidae), Mark Andrew Boston

OES Theses and Dissertations

The present study investigates the interfertility of Palaemonetes populations, Interspecific crosses were attempted between representatives of sympatric :populations of P. pugio, P. vulgaris, and P. intermedius, Intraspecific crosses were undertaken between geographically separated :populations of P. pugio. Laboratory conditions of 25°c, 25°/oo, and 14.5 hour photoperiod per day were maintained for all breeding attempts, Under these conditions interspecific hybridization of Palaemonetes pugio and P. vulgaris was not feasible. P. intermedius could not be hybridized with P. pugio and P. vulgaris. At 40 days of age P. pugio juveniles were significantly larger than P. vulgaris juveniles of …

Distribution And Habitat Of The Taillight Shiner, Notropis Maculatus (Hay), In Arkansas, Henry W. Robison Jan 1978

Distribution And Habitat Of The Taillight Shiner, Notropis Maculatus (Hay), In Arkansas, Henry W. Robison

Journal of the Arkansas Academy of Science

The distribution of the taillight shiner, Notropis maculatus (Hay), within Arkansas is discussed based on personal collections, literature citations and a search of museum records. N. maculatus appears to be a typical Coastal Plain physiographic province inhabitant occurring below the Fall Line, and it nears its western and northern range limits west of the Mississippi River in Arkansas. Data are provided on preferred habitat, and suggestions are provided as to the current status of the taillight shiner within Arkansas.

Species Composition And Diversity Of Hawk Populations In Northeastern Arkansas, Earl L. Hanebrink, Keith B. Sutton, Alan F. Posey Jan 1978

Species Composition And Diversity Of Hawk Populations In Northeastern Arkansas, Earl L. Hanebrink, Keith B. Sutton, Alan F. Posey

Journal of the Arkansas Academy of Science

Species composition and diversity of hawk populations were analyzed for northeastern Arkansas by the use of roadside censuses conducted in September through April from 1974- 1977. Data from 10 years of Jonesboro Christmas Bird Counts were also analyzed. During the roadside survey 20,174 miles were driven and 1819 raptors were counted. Ten species were observed with the Red-tailed Hawk being most abundant followed by the Marsh Hawk and the American Kestrel. Eight species were recorded from the 10 years of Christmas Bird Counts. Annual breeding bird surveys and spot records turned up three additional species making a total of 14 …

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 …


Interactions In Lambdoid Bacteriophage Populations, Bruce Edward Mitchell Jan 1978

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. …
