Microhabitat Distribution And Its Effect Of Prey Utilization In Sympatric Populations Of Plethodon Glutinosus And Plethodon Dorsalis In Northwestern Arkansas, James M. Britton
Microhabitat Distribution And Its Effect Of Prey Utilization In Sympatric Populations Of Plethodon Glutinosus And Plethodon Dorsalis In Northwestern Arkansas, James M. Britton
Journal of the Arkansas Academy of Science
A study was done on sympatric populations of Plethodon glutinosus and P. dorsalis in northwestern Arkansas to determine the relative distribution of the two species and the relationship between their distribution and the utilization of available prey. Upon capture, total length, location, and habitat type were recorded for each salamander. Stomach content samples were obtained by forced regurgitation, and the animals were released. Samples of the local litter fauna were taken to determine prey availability. Habitat data were obtained for 171 salamanders; 76 P. glutinosus and 95 P. dorsalis. Stomach content samples were taken from 67 salamanders; 32 P. glutinosus …
Seasonal Abundance, Movement And Diversity Of Fishes In An Ozark Stream, Michael R. Dewey
Seasonal Abundance, Movement And Diversity Of Fishes In An Ozark Stream, Michael R. Dewey
Journal of the Arkansas Academy of Science
Seasonal fluctuations in fish abundance in Mud Creek occurred throughout the year at all sampling stations. At the two upper stations abundance was high and unstable during winter and early spring and decreased after heavy rainfall in mid-April. Abundance was low throughout the summer months, increasing in the fall due to large numbers of young-of-the-year. However, a different seasonal cycle occurred at the lower station which included deeper pools. Numbers were low and stable throughout the winter and early spring but high and unstable during the summer. Bigeye shiners (Notropis boops) and bluntnose minnows (Pimephales notatus) were the most mobile …

Biology Of The Striped Bass, Morone Saxatilis, In Beaver Reservoir, Arkansas, Raj V. Kilambi, Alex Zdinak Jr.
Journal of the Arkansas Academy of Science
Growth, length-weight relationship, maturation and food habits of striped bass from Beaver Reservoir were studied. No significant difference in growth in length between sexes was found. Growth of the Beaver Reservoir striped bass was similar to that of anadromous and freshwater populations. Males and females showed significant difference in length-weight relationship, and females exhibited isometric growth. The gonosomatic indices (GSI) of males ranged from 4.50 to 7.09 and were classified as mature fish. Female striped bass with GSI of 2.62 and above had three size groups of ova and were considered as maturing and mature. The food was primarily composed …
Classification And Protection Status Of Remnant Natural Plant Communities In Arkansas, William F. Pell
Classification And Protection Status Of Remnant Natural Plant Communities In Arkansas, William F. Pell
Journal of the Arkansas Academy of Science
A classification and inventory of Arkansas's remaining tracts of relatively undisturbed vegetation was initiated in 1979. Based on extensive literature surveys and field work, the classification includes five physiognomic classes, 17 cover classes, and 46 cover types, arranged hierarchically. High quality examples of ten of the cover types have been located in designated wilderness or state natural areas, where they are protected by law, while an additional three occur in research natural areas or Forest Service special interest areas. The remaining 33 cover types have no known long-term protection. Lands having wilderness, state natural area, research natural area, or special …
Preliminary Report On The Fishes Of The Upper Saline River, Polk And Howard Counties, Arkansas, And Observations On Their Relationships With Land Use And Physiochemical Conditions, Stephen A. Sewell
Journal of the Arkansas Academy of Science
The Saline River of southwest Arkansas was impounded by Dierks Lake in 1975. Intensive collecting efforts were made in the river system above Dierks Lake during March, April, and May 1980. Collected specimens were compared with ichthyofaunal lists prior to impoundment. Historic occurrants which were not collected include Notropis amnis, Notropis ortenburgeri, Moxostoma duquesnei, Ammocrypta vivax, and Percina copelandi. Additions to the ichthyofaunal list for the drainage include Fundulus notatus, Etheostoma spectabile, and Percina caprodes. The evidence indicates that 33 species representing six families inhabit the system from the headwaters in Polk County, Arkansas, to Dierks Lake, Howard County, Arkansas. …
Maturation, Spawning Period, And Fecundity Of The White Crappie, Pomoxis Annularis Rafinesque, In Beaver Reservoir, Arkansas, Janet L. Thomas, Raj V. Kilambi
Maturation, Spawning Period, And Fecundity Of The White Crappie, Pomoxis Annularis Rafinesque, In Beaver Reservoir, Arkansas, Janet L. Thomas, Raj V. Kilambi
Journal of the Arkansas Academy of Science
Gonosomatic indices and ovum diameter frequency distributions showed that the Beaver Reservoir white crappie spawns from late April through May. During the spawning season females release eggs more than once. Various stages of ovarian ovum development were described. Sexual maturity was found in 2-year-old females of 197 mm and 3-year-old and older fish. Regression analyses of fecundity on total length, weight and age of white crappie indicated that the fish weight was the best predictor of fecundity.
Fluorgraphic Technique For Detecting And Recording Chlorophyll And Its Derivatives On Paper And Thin-Layer Chromatograms, James L. Wickliff
Fluorgraphic Technique For Detecting And Recording Chlorophyll And Its Derivatives On Paper And Thin-Layer Chromatograms, James L. Wickliff
Journal of the Arkansas Academy of Science
Light from a blacklight lamp (General Electric BLB) is restricted to a waveband range 360 - 470 nm by cut-off filters consisting of 4cm 1 M aqueous CuSO4 and acrylic plastic sheets. This filtered lamp emission is used to excite the characteristic red fluorescence of chlorophyll and its derivatives on paper or thin-layer chromatograms. Fluorescent spots are detected and recorded by exposure of red-sensitive panchromatic photographic printing paper (Kodak Panalure) to the fluorescing chromatogram. A thin yellow filter interposed between the chromatogram and the photo print paper restricts the detected fluorescence to wavelengths greater than about 500 nm. Standard development …

Effects Of Purified Salmonella Enteritidis Endotoxin On The Immune Response Of Balb/C Mice, John B. Barnett, John W. Jutila
Journal of the Arkansas Academy of Science
Wasting disease was produced in neonatal Balb/c mice with purified Salmonella enteritidis endotoxins. The endotoxins were chemically characterized to provide the study with a potent endotoxin with constant biological activity. Neonatal mice received an initial injection of 35 μg/g body weight of endotoxin and a dose of 75 μg every third day until day 18. The degree of wasting was estimated by the runting (weight loss) index. Mortality was calculated to be 46%, with a mean survival time of approximately 15 days. The hematologic studies conducted at days 10, 20, and 30 showed an absolute neutrophilia and leukocytosis by day …

Flying Insect Populations As Sampled By Malaise Trap On Crowley's Ridge In Northeast Arkansas, Lynita M. Cooksey, Harvey E. Barton
Journal of the Arkansas Academy of Science
Malaise trap collections from woodlot and open field sampling sites on Crowley's Ridge yielded 10,830 individuals during the months of May, July and September, 1980. Greatest numbers of insects were collected in May, with fewest in September. Four orders comprised 97% of the total catch: Diptera (57%), Lepidoptera (17%), Hymenoptera (15%) and Homoptera (8%). Coleoptera, Hemiptera, Neuroptera, Odonata and Orthoptera comprised the remaining 3%. Ordinal composition and seasonal occurrence patterns are discussed and compared for the two sampling sites.
Non-Measles Hemadsorption In A Cell Line Persistently Infected With Measles Virus (Bgm/Mv), Jay H. Menna, John D. May
Non-Measles Hemadsorption In A Cell Line Persistently Infected With Measles Virus (Bgm/Mv), Jay H. Menna, John D. May
Journal of the Arkansas Academy of Science
Adsorption of Rhesus monkey erythrocytes to the plasma membranes of measles virus infected cells is frequently carried out to detect the presence of plasma membrane-associated measles virus hemagglutinin. The hemagglutinin is a viral genome-coded structural glycoprotein of the measles virion that is associated with the plasma membrane of the host cell during measles virus replication. BGM/MV, anon-virogenic line of African green monkey kidney cells persistently-infected with measles virus, adsorbed Rhesus monkey erythrocytes in an inverse fashion relative to the number of cells present in the culture and the time post-seeding. Serological studies employing the hemadsorption-inhibition and membrane immunofluorescence assay procedures, …
River Otter In Arkansas: I. Distribution And Harvest Trends, C. Renn Tumlison, Anthony W. King, Lew Johnston
River Otter In Arkansas: I. Distribution And Harvest Trends, C. Renn Tumlison, Anthony W. King, Lew Johnston
Journal of the Arkansas Academy of Science
River otter (Lutra canadensis) management in Arkansas is hampered by a lack of information on population parameters. This initial study on the biology of Arkansas river otter is concerned with present distribution and harvest trends. Otter occur throughout Arkansas, except in the upper Ozark region. A distributional shift, apparently along the Arkansas River, has led to an increase in otter harvest in the Ouachita Mountain region. A dramatic increase in otter harvest over the past four years (1976-1979) is attributable, in part, to a pelt price increase. Additionally, nuisance level beaver (Castor canadensis) populations and an extended trapping season for …

Aquaculture Industry Of Arkansas In 1979-1980, Donald H. Fiegel, Mike Freeze
Journal of the Arkansas Academy of Science
A survey of previous fish farmer certificate holders in Arkansas was conducted during 1979-1980 using renewal questionnaires, telephone conversations, and personal contacts. This survey was compared with similar surveys from preceding years. Approximately 51.0% of 12,372 intensively farmed hectares in 1979-80 were devoted to bait fish production, while 22.9% were utilized in food fish production. Acreage in bait fish, food fish, and fingerling production decreased from 1979 to 1980; however, price increases during this time resulted in a higher total value of the industry
