Cartographic Trend Analysis Of Furbearer Harvest Distributions In Arkansas, C. Renn Tumlison, Mark Trail, V. Rick Mcdaniel Jan 1987

Cartographic Trend Analysis Of Furbearer Harvest Distributions In Arkansas, C. Renn Tumlison, Mark Trail, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Average by-county fur harvest for the last nine harvest seasons (1977-1985) was used as data points to be interpolated using nearest neighbor algorithms in computer-assisted trend analyses. COMPLOT maps were produced which represented a surface of harvest densities drawn over a map of Arkansas. Twelve furbearer species are examined, and "topographic" features of harvest density for each are interpreted in terms of ecology and/or buyer distribution. The trend surface technique removed some of the error inherent to harvest records, and produced an aesthetic graphical display of the information that was more easily interpreted and explained than other methods of analysis …

Dimilin For Control Of Lernaea In Golden Shiner Ponds, Gary Burtle, John Morrison Jan 1987

Dimilin For Control Of Lernaea In Golden Shiner Ponds, Gary Burtle, John Morrison

Journal of the Arkansas Academy of Science

A single application of Oimilin (UNIROYAL),diflubenzuron, was tested in 9 (nine) ponds containing golden shiner minnows, Notemigonus crysoleucas, infested with the parasitic copepod Lernaea cyprinacea. The chemical was applied at a rate of1 0 or 30 pg/l and compared to untreated controls. Fish were periodically sampled to determine levels of infestation, and zooplankton numbers were monitored for chemical effect. Oimilin treatment significantly reduced (P < 0.05) parasite infestation four to eight days after treatment. No significant difference (P < 0.05) was noted between the two levels of treatment. Zooplankton populations decreased in the Dimilin treated ponds following chemical application. Rotifer populations rebounded later during the period, but copepod populations in the ponds treated with 30 ng/L remained depressed from two days after treatment for one month until the study ended. Complete parasite control was not obtained with either chemical concentration using a single application. These results suggest that a single treatment is not effective for Lernaea control. Future research will test two applications 10 days apart at the 10 and 30 /xg/L levels.

Effects Of Stock Type And Planter Experience On The Time Required To Plant Loblolly Pine Seddlings, Richard A. Kluender, Jimmie L. Yeiser Jan 1987

Effects Of Stock Type And Planter Experience On The Time Required To Plant Loblolly Pine Seddlings, Richard A. Kluender, Jimmie L. Yeiser

Journal of the Arkansas Academy of Science

Inexperienced workers planted container-grown and bare-root seedlings of loblolly (Pinus taeda L.) on a rocky, upland site near Batesville, AR in a comparison of planting speed and survivability. Planting speed depended on the type of seedling planted and the amount of planting experience. Significantly less time was required to plant an acre with container-grown than bare-root seedlings. Experience increased the consistency and speed of planting for both seedling types.

Effects Of Blue Tilapia/Channel Catfish Polyculture On Production, Food Conversion, Water Quality And Channel Catfish Off-Flavor, Les Torrans, Fran Lowell Jan 1987

Effects Of Blue Tilapia/Channel Catfish Polyculture On Production, Food Conversion, Water Quality And Channel Catfish Off-Flavor, Les Torrans, Fran Lowell

Journal of the Arkansas Academy of Science

Channel catfish (Ictalurus punctatus) monoculture ponds stocked with 10,000/ha of mixed- size catfish were compared to ponds stocked additionally with blue tilapia (Tilapia aurea). Ponds stocked with 5000/ha young-of-the-year blue tilapia produced 236 kg/ha less catfish, but tilapia biomass increased by 1020 kg/ha, averaging 233 g/fish. Ponds stocked with sexually mature tilapia in Aprilto provide forage to the catfish had increased catfish production but a poorer food conversion radio. Ponds stocked with sexually mature tilapia in June or July had catfish production and FCR's similar to the controls. Dissolved oxygen was significantly lower than the controls in all polyculture treatments. …

Improved Synthesis Of 5-Methylbenz(A)Anthracene, Jia Che, Dominic T.C. Yang Jan 1987

Improved Synthesis Of 5-Methylbenz(A)Anthracene, Jia Che, Dominic T.C. Yang

Journal of the Arkansas Academy of Science

A revised synthesis of 5-methylbenz(a)anthracene is reported. It involves only three simple and convenient steps starting from a commercially available compound, and gives a 82% overall yield. Bromination of 5-methylbenz(a)anthracene with N-bromosuccinimide (NBS) in carbon tetrachloride furnishes 5-bromomethylbenz(a)anthracene in a 92% yield. When bromination is carried out using dimethylformamide as the solvent, 7-bromo-5-methylbenz(a)anthracene is formed as the exclusive product.

Hyla Versicolor-Chrysoscelis Species Complex Of Gray Treefrogs In Arkansas: Histological And Ultrastructural Evidence, Phyllis Chaffin, Stanley E. Trauth Jan 1987

Hyla Versicolor-Chrysoscelis Species Complex Of Gray Treefrogs In Arkansas: Histological And Ultrastructural Evidence, Phyllis Chaffin, Stanley E. Trauth

Journal of the Arkansas Academy of Science

We investigated the Hyla versicolor-chrysoscelis species complex (tetraploid and diploid species, respectively) of cryptic gray treefrogs from Arkansas using light and scanning electron microscopy. From previous studies of this treefrog complex in other states, H. versicolor has been shown to exhibit larger nuclear diameters and larger toe pad epithelial cells than H. chrysoscelis. Based upon average nuclear diameters of eyelid epithelial cells, we found two or possibly three groups of frogs. The presumed H. versicolor exhibited greatly enlarged toe pad epithelial cells using scanning electron microscopy and were found in four counties, three of which are in the Ozark Mountains. …

Clinostomum Marginatum Metacercaria: Incidence In Smallmouth Bass From A North Arkansas Stream And In Vitro Oxygen Consumption Studies, James J. Daly, Howard H. Conaway, Terryl L. Hostetler, H. Michael Matthews

Journal of the Arkansas Academy of Science

Small mouth bass (Micropterus dolomieui) captured from Crooked Creek (Marion Co., Arkansas) in the summers of 1977 and 1987 were found to have a high incidence of infection with the metacercaria of Clinostomum marginatum (yellow grub). Of 41 fish collected in 1977, 32 (78%) were found infected with metacercariae with some fish containing large numbers of parasites. The number of larvae per fish ranged from 1 to 184, with an average of 23.2 ± 38 per smallmouth. Eighty-six percent of the bass collected in 1987 were found positive for C. marginatum. The number of metacercariae per fish ranged from 1 …

Distribution Of Fish Within Headwater Riffles Of The Illinois River System, Washington County, Arkansas, Danny J. Ebert, Arthur V. Brown, Carolyn B. Fielder

Journal of the Arkansas Academy of Science

Quantitative sampling of fish was performed in five headwater riffles of the Illinois River System, Washington County, Arkansas during low flow conditions. This study revealed differing fish species composition, biomass and feeding guild segregation between head and tail riffle reaches in 1st through 3rd order. Thirty species representing 10 families were identified. Of this number, darters (Percidae), sculpins (Cottidae), madtoms (Ictaluridae), and central stonerollers (Campostoma anomalum) (Cyprinidae) comprised 67 to 98 percent of riffle head populations. Fish biomass was greater for riffle head areas (0.58-6.6/0.28-2.0 g/m2 ) within sectivores and herbivores dominating. Total fish numbers decreased from riffleheads to tails, …

Distribution Of Fishes In Reference Streams Within Arkansas' Ecoregions, William E. Keith Jan 1987

Distribution Of Fishes In Reference Streams Within Arkansas' Ecoregions, William E. Keith

Journal of the Arkansas Academy of Science

The State of Arkansas has been subdivided into six ecoregions based on the homogeneity of land surface forms, potential natural vegetation, soil types and land uses. Reference streams of various sizes, excluding the large rivers, and with the least amount of point source and non-point source disturbances were selected for intensive physical, chemical and biological sampling. These data are to be used to characterize the streams and establish water quality criteria which will protect all stream uses. Fish communities of the reference streams were distinctively different among the ecoregions and can easily be used to characterize the waters of different …

Status Of The Instream Flow Issue In Arkansas, 1987, Stephen P. Filipek, William E. Keith, John Giese

Journal of the Arkansas Academy of Science

Expansion of Arkansas' population with concurrent increases in the state's domestic, industrial, and agricultural water uses and possible out-of-state diversion are placing substantial demands on the state's water resources. In an attempt to address this growing concern, Act 1051 (1985) of the Arkansas legislature was passed requiring the determination of present and future state water needs. A specific area of this mandate was the quantification of instream flow requirements. Basic instream flow needs are maintenance of the aquatic ecosystem and dependent riparian environment. Flow reservation may compliment other instream uses such as recreation, navigation, water quality, and groundwater recharge. However, …

Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr. Jan 1987

Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr.

Journal of the Arkansas Academy of Science

The United States government established a trading house at Arkansas Post in 1805 on the north bank of the Arkansas River in the newly purchased Louisiana Territory. The goal of this trading house was to foster good relations with the Quapaw tribe and other indigenous peoples. John B. Treat and his successors operated the post and meticulously recorded the number, value, and species of pelts traded. Tabulation of these records, which have been preserved in the National Archives, revealed that 9 or 10 species contributed a total of about 44,000 hides, worth approximately $18,000. White-tailed deer (Odocoileus virginianus) pelts comprised …

Physiography And Hydrology Of The Upper Saline River, Saline And Garland Counties, Arkansas, John D. Rickett Jan 1987

Physiography And Hydrology Of The Upper Saline River, Saline And Garland Counties, Arkansas, John D. Rickett

Journal of the Arkansas Academy of Science

The Saline River is one of two significant river systems in Arkansas that does not have a major impoundment. In the interest of continuing this status, this project was conducted. Thirty-five sites on the four major and six minor tributaries of the upper saline River, Saline and Garland Counties, Arkansas, were visited a total of 58 times between 24 January 1985 and 21 November 1986. Habitat quality was assessed by measuring twelve physicochemical features and flow parameters, analyzing substrate composition and describing stream morphometry. Physicochemical measurements were within the limits of good quality habitat, and most of the readings were …

Long-Term Effects Of Tillage On The Retention And Transport Of Soil Water, H. D. Scott, L. S. Wood, W. M. Miley

Arkansas Water Resources Center Technical Reports

Quantitative measurements were made of the physical and chemical properties of two virgin prairie soils, Crowley and Jay, that remain in their native Arkansas environments and of similar soils that had been tilled extensively. Comparisons were made of soil properties at several depths. When compared with the tilled soils the virgin soils had higher organic matter contents, saturated hydraulic conductivities and water retained at several applied pressures. Bulk densities and hydraulic resistances were lower in the virgin soils. For the Crowley silt loam, values of pH and elemental contents of the virgin soil were higher than those of the tilled …
