Systematic Status Of The Fishes Of Genus Campostoma (Cyprinidae) Inhabiting The Major Drainages Of Northern Arkansas, Stephen A. Sewell, John K. Beadles, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

A total of 6980 morphometric and meristic data points were analyzed from specimens previously identified as Campostoma anomalum pullum and Compostoma oligolepis from all areas of their Ozark ranges in Arkansas. Data were analyzed using the Statistical Analysis System (SAS) and IBM 370 Computer System (HASP II). An attempt was made to establish separation points through multivariate analysis (MANOVA) by taxon and watershed. Additional analyses included factor analysis and discriminant function analysis. Scale count frequencies were analyzed using computer program MINITAB. MANOVA revealed a lack of consistent separation points, and Ozark populations were shown to be distinct and highly variable …

Hematology As Related To Diving Characteristics Of Elaphe Obsoleta, Nerodia Erythrogaster, Nerodia Fasciata And Nerodia Rhombifera, Dennis A. Baeyens, M. W. Patterson, Chris T. Mcallister

Journal of the Arkansas Academy of Science

The diving capabilities of Nerodia erythrogaster flavigaster and Nerodia fasciata confluens were investigated and the results were compared with similar studies on Nerodia rhombifera rhombifera and Elaphe obsoleta obsoleta (Baeyens et al., 1978). In addition, morphological and hematological parameters contributing to underwater survival were examined. The duration of underwater survival for N. erythrogaster and N. fasciata was approximately one hour with no difference between the species. The lung volumes of the two species were also similar but were significantly less than lung volumes reported for E. obsoleta. There were no significant differences in hemoglobin concentration, red blood cell count or …

Abundance, Diversity And Distribution Of Benthic Macro-Invertebrates In The Flat Bayou Drainage Area, Jefferson County, Arkansas, John D. Rickett

Journal of the Arkansas Academy of Science

The main ditch of Flat Bayou Drainage in north central Jefferson County carries water southward into Plum Bayou which then shortly empties into the Arkansas River. Flat Bayou proper flows northward into Wabbaseka Bayou which in turn flows into the Arkansas River in northeastern Lincoln County. Two sites on the main ditch were sampled for physico-chemical parameters and benthic macroin vertebrates on 9 September, 7 October and 11 November 1978. No visible detrimental effects were attributed to physico-chemical characteristics. Thirty-one below-family taxa and 19 families were found in abundance from zero at one site and date to 3580 per m² …

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. …

Attraction Of Aerial Insects As A Fish Food Supplement, Andrew J. Merkowsky, Ambus J. Handcock, Scott H. Newton Jan 1977

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

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.

Growth, Mortality, Food Habits, And Fecundity Of The Buffalo River Smallmouth Bass, Raj V. Kilambi, Walter R. Robison, James C. Adams

Journal of the Arkansas Academy of Science

Total length-scale radius, and length-weight relationships were determined for smallmouth bass from the Buffalo River. The back calculated lengths were used in analyzing the age-length data by the Bertalanffy growth formula. Asymptotic length and weight were estimated as 58.3 cm and 4.6 lbs, respectively. Annual mortality of 36 percent was estimated by the catch curve method. Insects (54%), fishes (16%), and crayfish (14%) were the abundant food organisms by frequency of occurrence; while fishes (64%) and crayfish (29%) were the dominant food items by the gravimetric method. Based on the gonosomatic indices and frequency distribution of ovum diameter measurements, smallmouth …
