Food Deprivation And The Regulation Of Meal Size In Larvae Of Chrysopa Carnea, Alan B. Bond

Alan Bond Publications

The course of repletion and the effects of food deprivation on meal size were explored in three experiments on larvae of Chrysopa carnea (Neuroptera). Feeding to repletion was found to occur within the first 30 min of exposure to food. Meal size increased as an ogival function of deprivation, up to the limit of gut capacity. Behavioral components involved in the initiation of feeding were little affected by deprivation and did not appear to be inhibited by distention of the gut. Termination of a meal may be mediated by the stimulation of prey-release behavior, rather than by inhibition of feeding.

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 …

Studies On The Role Of Solar Ultraviolet Radiation In "Natural" Water Purification By Aquatic Ecosystems, John Calkins, Jeanne A. Barcelo, Perry Grigsby, Stephen Martin

KWRRI Research Reports

The possibility that pollution might deplete the stratospheric ozone layer and intensify solar UV at the earth's surface focuses attention on the role of solar UV in the various ecosystems at the earth's surface. Previous studies suggested that solar UV might contribute to bacterial die off in wastewater and the studies reported here were directed toward elucidating the action of solar UV in "natural" waters.

It has been assumed that solar UV action on aquatic ecosystems can be evaluated (using proper models) on the basis of the following four independently measurable quantities: I) the intensity of solar UV at the …

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. …

Range And Status Of The Nutria, Myocastor Coypus, In Arkansas, Joe W. Bailey, Gary A. Heidt

Journal of the Arkansas Academy of Science

An extensive survey has shown that the current range of the nutria, Myocastor coypus. in Arkansas should include the West Gulf Coastal Plain, the Mississippi Alluvial Plain (to Missouri) and the Arkansas Valley along the Arkansas River to Oklahoma. The extensive river and creek systems in the state have provided ready avenues for dispersal, allowing for extremely rapid expansion from the early 1960's when nutria were first observed in the southern part of the state. The current range probably represents most of the suitable habitat in the state and it is felt that further expansion will be held to a …

Movements Of Channel Catfish And Flathead Catfish In Beaver Reservoir, Northwest Arkansas, Thomas O. Duncan, Milton R. Myers Jr.

Journal of the Arkansas Academy of Science

A total of 497 channel catfish, Ictalurus punctatus, and flathead catfish, Pylodictis olivaris. were tagged in Beaver Reservoir during two November-April tagging periods (1967-68 and 1968-69); total recaptures were 9.5 and 11.7% respectively. The longest time between tagging and recapture was 1622 days (4.4 years) for channel catfish and 494 days (1.4 years) for flathead catfish. The longest distances traveled were 43.1 km by a channel catfish and 44.3 km by a flathead catfish. Fisherman returns indicated that catfish were caught primarily from April through July. The many recaptures, even after long periods, within 1.6 km of the tagging point, …

Fishes Of The Caddo River, Arkansas, After Impoundment Of Degray Lake, Michael R. Dewey, Thomas E. Moen

Journal of the Arkansas Academy of Science

Fifty-five collections of fishes were made with small-mesh seines and electrofishing gear in the Caddo River and four of its tributaries during 1974-75. Eighty-two species representing 17 families were collected; 14 of the species had not previously been reported from the Caddo River.

Summary Of The Status Of Harvest Mice, Cricetidae: Reithrodontomys, In Arkansas, V. Rick Mcdaniel, John C. Huggins, James A. Huggins, Michael W. Hinson

Journal of the Arkansas Academy of Science

Although four species of harvest mice, Reithrodoniomyx, are known to occur in Arkansas, the distributional status of the genus in the state is poorly understood. Recent museum specimens significantly extend the range of R. megalotix and R. fulvescens in the state. R. megalotis is shown to range south through Phillips Co. in eastern Arkansas, and R. fulvescens is shown to range throughout most of the state, now including most of the Mississippi Alluvial Plain. A new specimen of R. humulis from Delaware Co., Oklahoma, suggests that this species probably ranges throughout northwestern Arkansas. R montanus remains known only from Washington …

Fishes Of Morrow Creek, A Lower Ouachita River Tributary, In Southern Arkansas, Henry W. Robison, Stephen A. Winters

Journal of the Arkansas Academy of Science

The fishes of Moro Creek, a fifth order stream tributary of the lower Ouachita River in southern Arkansas, were sampled from 1972-1977. Field collections, literature records and museum records revealed a total of 63 species representing 14 families. An undescribed cyprinid, the bluehead shiner, is reported from Moro Creek for the first time. In general, longitudinal zonation of fish species was apparent as species diversity increased downstream. Stream inhabitants were typical Coastal Plain fishes of the lower Ouachita River system.

Influence Of Lead, An Environmental Pollutant On Metamorphosis Of Rana Utricularia (Amphibia: Ranidae), Gloria L. Yeung

Journal of the Arkansas Academy of Science

The influence of lead, an environmental pollutant on metamorphosis of Rana utricularia, was examined in this study. Larvae of stage XI (Taylor and Kollros, 1946), beginning of the premetamorphic stage, were exposed to lead concentrations of 0.1 ppm, 0.5 ppm, 1.0 ppm and 1.5 ppm for 106 days. The untreated larvae served as controls. Larvae were observed from early limb bud stage, stage X, through the protrusion of the forelimbs, stage XX. Neither the sequence of developmental events nor the gross external and internal morphology was altered by lead. However, lead prolonged the time of metamorphosis by delaying the completion …

Some Physiological And Morphological Adaptations For Underwater Survival In Natrix Rhombifera And Elaphe Obsoleta, Dennis A. Baeyens, Chris T. Mcallister, Leland F. Morgans

Journal of the Arkansas Academy of Science

The submergence times of the diamondback water snake (Natrix rhombifera) and black rat snake (Elaphe obsoleta) were compared. Both species could easily survive underwater for periods greater than one hour. Furthermore, there was no difference in time of underwater survival in the two species. Some physiological and morphological parameters which may contribute to the ability of N. rhombifera and E. obsoleta to remain submerged were also examined. E. obsoleta was found to have a greater lung volume and larger and more numerous alveoli than N. rhombifera. Both species demonstrated a bradycardia upon submergence but it was less pronounced than the …

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 …

Relating Wolf Scat Content To Prey Consumed, Theodore J. Floyd, L. David Mech, Peter A. Jordan

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

In 9 trials, captive wolves (Canis lupus) were fed prey varying in size from snowshoe (Lepus americanus) to adult deer (Odocoileus virginianus), and the resulting scats were counted. collectible scats were distinguished from liquid, noncollectible stools. In collectible scats, the small prey occurred in greater proportion relative to the prey's weight, and in lesser proportion to the prey's numbers, than did the remains of larger prey. A regression equation with an excellent the data (r² = 0.97) was derived to estimate the weight of prey eaten per collectible scat for With this information …

Zoogeography Of Antillean Bats, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Analysis of the bat fauna of the Antillean Islands suggest that the most probable source of invasion of the islands by bats is by overwater dispersal. The bat fauna of ·the Greater Antilles is unique, a percentage of endemism on each island being over 50 percent except for the Virgin Islands which has 33 percent endemics.

The richest bat fauna in the Antilles is on Cuba (32 species) followed by Jamaica (23 species) then Hispaniola (17 species) and Puerto Rico (16 species). The number of species found on Cuba is probably the result of the island's proximity to Central and …
