Eggtooth Development And Morphology In The Six-Lined Racerunner Cnemidophorus Sexlineatus (Sauria: Teiidiae) Using Scanning Electron Microscopy, Stanley E. Trauth Jan 1988

Eggtooth Development And Morphology In The Six-Lined Racerunner Cnemidophorus Sexlineatus (Sauria: Teiidiae) Using Scanning Electron Microscopy, Stanley E. Trauth

Journal of the Arkansas Academy of Science

Eggtooth development and morphology in the six-lined racerunner, Cnemidophorus sexlineatus, were examined using scanning electron microscopy. The anlage of the embryonic eggtooth emerges from the anterior surface of the palate relatively late during embryonic development. The eggtooth proper erupts through an epithelial sheath and grows anteriorly to project beyond the rostral scale. The mature eggtooth is hollow, has a wall made of enamel and dentine, possesses a sharply-curved body and has a flattened, pointed tip. The eggtooth is shed within several days after the young hatch.

Forest Habitat Use By White-Tailed Deer In The Arkansas Coastal Plain, T. B. Wigley Jr., M. E. Garner Jan 1988

Forest Habitat Use By White-Tailed Deer In The Arkansas Coastal Plain, T. B. Wigley Jr., M. E. Garner

Journal of the Arkansas Academy of Science

Forest habitat use by five radio-equipped white-tailed deer (Odocoileus virginianus) was monitored in the Arkansas Coastal Plain during 1982-84. The deer were located 821 times. Use of forest types was compared to expected use as calculated from availability. The study area was also divided into 491 two-hectare cells for which timber characteristics and number of deer locations were determined. Pine sawtimber was the most heavily used forest type in all seasons and was used more often than expected during spring. Also used more than expected were brushy areas (clearcut but not site prepared) during spring, summer and fall and openings …

A Stereotaxic Atlas Of The Brain Of The Chick (Gallus Domesticus), Wayne J. Kuenzel, Manju Masson

Poultry Science Faculty Publications and Presentations

Nine brains taken from chicks two weeks of age were used for the development of this atlas. Each chick was first anesthetized with an intravenous (IV) injection of Chloropent2 (1.8 ml/kg). Chicks were then perfused via the heart with 90 ml physiological saline followed by 90 ml Heidenhain's3 solution. Each head was then positioned in a stereotaxic instrument as described in the previous section and three stainless steel (SS) insect pins (#2) were implanted in each brain at known coordinates. In the case of the brains used to construct the cross- sectional atlas plates, two pins were implanted horizontal to …

Estimating Potential Ground And Surface Water Pollution From Land Application Of Poultry Litter, J. T. Gilmour, D. C. Wolf, P. M. Gale Jun 1987

Estimating Potential Ground And Surface Water Pollution From Land Application Of Poultry Litter, J. T. Gilmour, D. C. Wolf, P. M. Gale

Arkansas Water Resources Center Technical Reports

In 1985, more than 750 million broiler chickens were produced in Arkansas. During the same year over 15 million laying chickens produced 3.6 million eggs. The waste products of these agricultural production systems, poultry litter and manure, were about 1 million metric tons. As a result of land application of these wastes, about 5,000 metric tons of annnonium N and 12,000 metric tons of mineralized nitrogen were applied to Arkansas pastures in 1985. Manures contributed about 2-3 percent of the total. The objective of this research was to quantify major components of the nitrogen cycle which influence the ground and …

Residual Pesticides In Fishes From Lake Chicot, Arkansas, C. M. Cooper, S. S. Knight Jan 1987

Residual Pesticides In Fishes From Lake Chicot, Arkansas, C. M. Cooper, S. S. Knight

Journal of the Arkansas Academy of Science

Samples of fish from isolated and flow-through portions of Lake Chicot, Arkansas, were analyzed for residual pesticide concentrations from 1978 and 1981. Where appropriate ecologically, fish flesh, viscera and whole fish, were analyzed for the common organochlorine insecticides DDT [1,1 ,1-trichloro -2,2bis(p-chlorophenyl)-ethane], DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)-ethyene], DDD [1,1-dichloro -2,2-bis(p-chlorophenyl)-ethane], toxaphene (chlorinated camphene), chlordane, heptachlor, heptachlor epoxide, dieldrin, and endrin. DDT, DDT metabolites, and heptachlor were significantly (a = 0.05) higher in spotted gar (Lepisosteus oculatus) and yellow bullhead catfish (Ictalurus natalis) than in other species examined. Pesticide concentrations did not exceed the acceptable levels established by the U.S. Environmental Protection Agency although …

Photoreactivation Of Lethal Damage Induced In Hamster X Xenopus Hybrid Cells And Their Parentals By Uv Light, David Bohlender, Stuart Williams, Emir Cruz, H. Gaston Griggs Jan 1987

Photoreactivation Of Lethal Damage Induced In Hamster X Xenopus Hybrid Cells And Their Parentals By Uv Light, David Bohlender, Stuart Williams, Emir Cruz, H. Gaston Griggs

Journal of the Arkansas Academy of Science

A85 Xenopus cells that exhibited a high level of photoreactivation (PR) and V79B2 hamster cells that exhibited little PR were fused to produce the V79B2 x A85 cell line — a hybrid line which possessed a relatively stable karyotype, with most cells containing the entire V79B2 and A85 genomes. UV and UV plus PR fluence-survival relations were then determined and compared for the hybrid and parental lines in a first attempt to elucidate interactions of the parental PR mechanisms in the hybrid. It was anticipated that the A85 genome in the hybrid would produce PR enzyme in sufficient concentration and …

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 …

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. …

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. …

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 …

Age And Growth Of Redear Sunfish Lepomis Microlophus (Gunthur), From Bob Kidd Lake, Rex R. Roberg, Thoniot T. Prabhakaran, Raj V. Kilambi

Journal of the Arkansas Academy of Science

Total lengths (62-285mm) and body scales from 75 redear sunfish collected by electroshocking from Bob Kidd Lake during October and November 1985 were used for this study. The length-frequency distribution yielded five age groups, however, the body scale analysis revealed eight age groups. The total length scale radius relationship was estimated as, TL = 17.98 + 0.92 Sr . Lengths attained at earlier ages were estimated by the Fraser-Lee method and the Bertlanffy growth model was fitted to the lengths for ages five through ten, and the resulting equation, L₁ = 295 [1 - exp — 0.29 (t - 1.83)], …

River Otter In Arkansas. Iv. Winter Food Habits In Eastern Arkansas, C. Renn Tumlison, Anthony W. King, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Stomachs and intestines of 89 river otters (Lutra canadensis) collected in eastern Arkansas during the trapping seasons (December- January) of 1978-1983 were examined for food remains. Fish (primarily centrarchids, catostomids, and clupeids) dominated the diet (71.2%). The next most abundant prey was crayfish (18.3% of the diet). Other foods included gray squirrel (Sciurus carolinensis), wood duck (Aixsponsa), snakes (Thamnophis proximus), frogs (Ranidae and Hylidae), and beetles (Coleoptera).
