Summary Of The Status Of Harvest Mice, Cricetidae: Reithrodontomys, In Arkansas, V. Rick Mcdaniel, John C. Huggins, James A. Huggins, Michael W. Hinson Jan 1978

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 …

Influence Of Lead, An Environmental Pollutant On Metamorphosis Of Rana Utricularia (Amphibia: Ranidae), Gloria L. Yeung Jan 1978

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 …

Distribution, Habitat Notes, And The Status Of The Ironcolor Shiner, Notropis Chalybaeus Cope, In Arkansas, Henry W. Robison Jan 1977

Distribution, Habitat Notes, And The Status Of The Ironcolor Shiner, Notropis Chalybaeus Cope, In Arkansas, Henry W. Robison

Journal of the Arkansas Academy of Science

Field work throughout Arkansas since 1971 and a search of museum records have yielded 35 collections of the iron color shiner, Notropis chalybaeus Cope (Cyprinidae), not previously documented in Arkansas. From these data the iron color shiner is considered to be confined to the Coastal Plain physiographic province of Arkansas below the Fall Line, becoming most abundant in the Ouachita and Red River drainages of southern Arkansas. Notes on habitat preference, species associates, and current status of N. chalybaeus within Arkansas are presented.

Algal Assemblage Distribution As Related To Seasonal Fluctuations Of Selected Metal Concentrations, Ramona G. Rice, Richard L. Meyer Jan 1977

Algal Assemblage Distribution As Related To Seasonal Fluctuations Of Selected Metal Concentrations, Ramona G. Rice, Richard L. Meyer

Journal of the Arkansas Academy of Science

Seasonal variations of phytoplankton assemblages have been observed in a mildly eutrophic lake in northwestern Arkansas for six years. The data indicated that certain metal concentrations also varied seasonally. Sodium, potassium, calcium and magnesium ion concentrations, and phytoplankton composition and abundances were examined spatially and temporally. Four major algal blooms characterized the lake: a spring, a summer and an autumnal cyanophycean assemblage and a winter diatom-chrysophyte dominated population. Each metal concentration was inversely proportional to the abundance of the cyanophytes. The presence of the winter assemblage was accompanied by decreases in sodium, calcium and magnesium and increased levels of potassium. …

Time Course Of Pr Of Uv-Induced Chromosomal Aberrations And Lethal Damage In G1 Xenopus Cells, Jan Payne, H. Gaston Griggs Jan 1977

Time Course Of Pr Of Uv-Induced Chromosomal Aberrations And Lethal Damage In G1 Xenopus Cells, Jan Payne, H. Gaston Griggs

Journal of the Arkansas Academy of Science

Synchronous cultures of early G1 cells were exposed to UV and their ability to photoreactivate lethal and aberrational damage was determined as a function of time following UV exposure. Lesions leading to cell death were converted to a non-photoreactivable state before cells entered S phase, while lesions leading to chromosomal aberrations were converted to a non-photoreactivable state as the cells entered S phase. These results indicate that the intracellular mechanism which expresses photoreactivable UV-induced lesions in G1 cells as cell death is not identical to the mechanism which expresses such lesions as chromosomal aberrations, and the two mechanisms operate primarily …

Immunization Of Rats Against Mesocestoides Corti (Cestoda) By Subcutaneous Vaccination Of Living Tetrathyridia And By Passive Transfer With Serum, Jerry Y. Niederkorn Jan 1977

Immunization Of Rats Against Mesocestoides Corti (Cestoda) By Subcutaneous Vaccination Of Living Tetrathyridia And By Passive Transfer With Serum, Jerry Y. Niederkorn

Journal of the Arkansas Academy of Science

Laboratory rats were subcutaneously vaccinated with 100 live tetrathyridia of Mesocestoides corti (Cestoda) and subsequently intraperitoneally challenged with 50 tetrathyridia. Necropsy 30 days postinfection revealed that vaccinated rats harbored 97.4% fewer worms compared to control rats. In a second experiment, passive transfer of immunity was accomplished by immune serum from subcutaneously vaccinated rats. Rats receiving immune serum harbored 33.4% lighter worm burdens compared to normal serum recipients.

Attraction Of Aerial Insects As A Fish Food Supplement, Andrew J. Merkowsky, Ambus J. Handcock, Scott H. Newton

Journal of the Arkansas Academy of Science

Insect populations over a 1.2 hectare southeast Arkansas livestock pond were sampled to consider the possibility of their use as a fish food supplement. A commercial insect attraction unit was suspended above the pond, and attracted insects were collected. Insect populations were sampled 3-4 nights each month, January-December, 1976. Insects collected were identified and analyses were performed to determine nutritional composition and pesticide content. Insect samples were variable, however, 62% of the insects identified were in the Order Diptera and 97% of these were in the Family Chironomidae. Nutritional analyses revealed insects were more than 60% crude protein. Pesticide analysis …

The Distribution Of Cane, Arundinaria Gigante (Poaceae: Bambusoideae), Daniel L. Marsh Jan 1977

The Distribution Of Cane, Arundinaria Gigante (Poaceae: Bambusoideae), Daniel L. Marsh

Journal of the Arkansas Academy of Science

The distribution of cane in the United States was compiled on a county basis from previous records, correspondence, and field work. Ecological correlations were considered. The range appears to be limited primarily by temperature and precipitation. Two geographic populations correlate with major drainage divisions. The broad ecologic amplitude of cane is indicated by its occurrence in many different community types.

Fishes Of Crowley's Ridge In Arkansas, Robert F. Fulmer, George L. Harp Jan 1977

Fishes Of Crowley's Ridge In Arkansas, Robert F. Fulmer, George L. Harp

Journal of the Arkansas Academy of Science

Crowley's Ridge is one of the six natural geographic divisions of Arkansas which rises out of the Mississippi embayment as a relatively steep, uncultivated loessial mass. The ridge is drained by a network of headwater streams which are relatively clear with alkaline pH values and uniformly low alkalinity values. Carbon dioxide values were moderate and oxygen values were adequate. The fish species collected were basically headwater in composition. Isolated groups of characteristically upland species indicate that environmental quality of adjacent deltaic streams was better at one time.

Forest Communities Of Crowley's Ridge, G. Thomas Clark Jan 1977

Forest Communities Of Crowley's Ridge, G. Thomas Clark

Journal of the Arkansas Academy of Science

The forest communities of Crowley's Ridge in Arkansas were surveyed by sampling 22 selected stands which met predetermined criteria. The Importance Value (I.V.) for each woody species over one decimeter, diameter breast height (dbh), was derived from the combined values of relative density, relative dominance by basal area (B.A.), and relative frequency. Young trees under one decimeter, dbh, were assigned to three height classes from which frequency, density, and stratification data were derived. White Oak-Red Oak-Hickory is the general forest type. Its subdivisions: Oak-Hickory-Pine Forest, Mixed Oak-Hickory Forest, and White Oak-Beech Forest are advocated for practical field references. They are …

Comparative Studies Of The Witch Hazels Hamamelis Virginiana And H. Vernalis, Jack L. Bradford, Daniel L. Marsh Jan 1977

Comparative Studies Of The Witch Hazels Hamamelis Virginiana And H. Vernalis, Jack L. Bradford, Daniel L. Marsh

Journal of the Arkansas Academy of Science

An investigation of Hamamelis vernalis Sarg. and H. Virginiana L. was begun in southwestern Arkansas in the tall of 1976. An overlap of flowering periods occurred from late November through December, affording the possibility of hybridization. At one site the two taxa flowered simultaneously only 30 yards apart. Variation occurs in both taxa and there is a degree of overlap in most characters, but the composite of diagnostic features distinguishes the two species. The hybrid origin of H. vernalis suggested by Jenne (1966) does not seem likely.
