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 Jan 1980

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 …

Study Of Cumulative Growth-Inhibiting Factors In Recycled Water For Catfish Cultivation, R. W. Raible Apr 1979

Study Of Cumulative Growth-Inhibiting Factors In Recycled Water For Catfish Cultivation, R. W. Raible

Arkansas Water Resources Center Technical Reports

Channel catfish were grown in tanks with integral biological filters and complete recirculation of water. After the fish had resided in the tanks for 120 days, solvent extraction was performed on a portion of the tank water. Fresh pond-raised specimen channel catfish showed decreases in their heartbeat rates of about 20 percent when exposed to the extract. This metabolic disturbance is thought to be a factor in reducing the growth rate of fish held in close confinement in recirculating systems.

Status Of The Red-Cockaded Woodpecker At The Felsenthal National Wildlife Refuge In Arkansas, Douglas A. James, Fred L. Burnside Jr. Jan 1979

Status Of The Red-Cockaded Woodpecker At The Felsenthal National Wildlife Refuge In Arkansas, Douglas A. James, Fred L. Burnside Jr.

Journal of the Arkansas Academy of Science

The Red-cockaded Woodpecker is an endangered species that is endemic to mature pine forests of the southeastern United States. In Arkansas it presently occurs only in pinelands of the Ouachita Province and Gulf Coastal Plain. Cavity trees for nesting and roosting must be mature pines diseased with red-heart fungus. Due to recent forestry practices mature pine stands are disappearing thus reducing numbers of needed cavity trees. The Felsenthal National Wildlife Refuge in southeastern Arkansas contains high densities of Red-cockaded Woodpeckers and because of favorable management priorities there the survival of the woodpecker seems assured. Populations of the species in other …

Effects Of Channelization On Fish Populations Of The Cache River And Bayou Deview, Morris Mauney, George L. Harp Jan 1979

Effects Of Channelization On Fish Populations Of The Cache River And Bayou Deview, Morris Mauney, George L. Harp

Journal of the Arkansas Academy of Science

This study was designed to better understand the possible effects of channelization by comparing natural and previously channelized sections of the Cache River and Bayou DeView. Forty-five fish species were collected in natural reaches, but only 24 species were collected in channelized reaches. Cyprinus carpio and Dorosoma cepedianum constituted 40 and 20 percent of the total fish biomass in channelized reaches, respectively, but only 22 and 2 percent of the total biomass in natural reaches. The mean weight of total fishes and game fishes only per surface ha in natural sections were 276 and 46 kg, respectively, but these values …

Electrophoretic Analysis Of Blood Serum Proteins In Three Species Of Water Snakes (Genus Nerodia), Phyllis J. Garnett Jan 1979

Electrophoretic Analysis Of Blood Serum Proteins In Three Species Of Water Snakes (Genus Nerodia), Phyllis J. Garnett

Journal of the Arkansas Academy of Science

Serum from three species of water snakes (Nerodia rhombifera, N. erythrogaster and N. fasciata) from one geographic region was analyzed electrophoretically on cellulose acetate, and anodic mobility and relative concentration of the fractions were determined by a recording densitometer with an automatic integrator. Classification of fractions was based on mobility (Rf, values), and for identification purposes, bands were labeled in order of decreasing mobility (albumin and alpha₁, alpha₂, alpha₃, beta₁, beta₂, gamma₁, and gamma₂ globulins). Seven fractions were identified in each species with alpha₃ being absent from N. rhombifera and N. erythrogaster, and only one gamma fraction was observed in …

Age And Huddling As Determinants Of Metabolic Rate In Grasshopper Mice (Onychomys Leucogaster), Meredith Bailey, Dennis A. Baeyens, Lana Mann Jan 1979

Age And Huddling As Determinants Of Metabolic Rate In Grasshopper Mice (Onychomys Leucogaster), Meredith Bailey, Dennis A. Baeyens, Lana Mann

Journal of the Arkansas Academy of Science

The metabolic rates of grasshopper mice (Onychomys leucogaster) were determined every third day from birth to adulthood. Metabolic rates were quantitated by measuring oxygen consumption in an open circuit system. There was a rapid fall in oxygen consumption from the third day after birth until the ninth day. Mice which were housed separately assumed a constant metabolic rate at an earlier age than mice which were kept with litter-mates. The greatest increases in metabolism occurred when immature mice were separated from litter-mates for oxygen consumption determinations. It is concluded that huddling plays an important role in reducing the metabolic rate …

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 Jan 1979

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 …

Time Course Of Pr Of Uv-Induced Chromosomal Aberrations And Lethal Damage In S And G2 Xenopus Cells, Jan Payne, H. Gaston Griggs Jan 1979

Time Course Of Pr Of Uv-Induced Chromosomal Aberrations And Lethal Damage In S And G2 Xenopus Cells, Jan Payne, H. Gaston Griggs

Journal of the Arkansas Academy of Science

Sand G2 phase cells were exposed to 150 ergs mm⁻² UV and their ability to photoreactivate the induced cell killing (loss of colony forming ability) and chromosomal aberrations was determined as a function of time following the UV exposure. In S phase cells, the lesions leading to cell death and those leading to aberrations were both converted to a non-photoreactivable state shortly after the UV exposure. A significant fraction of the lesions induced in G2 cells, that led to cell death, were converted to a non-photoreactivable state before the progeny of the exposed cells reached the next succeeding S phase. …

Abundance, Diversity And Distribution Of Benthic Macro-Invertebrates In The Flat Bayou Drainage Area, Jefferson County, Arkansas, John D. Rickett Jan 1979

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 …

Effect Of Turf Fungicides On Earthworms, J. H. Roark, J. L. Dale Jan 1979

Effect Of Turf Fungicides On Earthworms, J. H. Roark, J. L. Dale

Journal of the Arkansas Academy of Science

Numerous turf fungicides were tested under various conditions for possible deleterious effects upon the earthworm Eisenla foetida. Earthworms treated by immersion for one minute in 0.1% solutions of 10 different fungicides died insignificant numbers after benomyl and thiophanate methyl treatments. After 1% fungicide treatments, there was significant mortality from benomyl, ethazole, Kromad, and thiophanate methyl fungicides. With 2% fungicide solutions, significant numbers died after benomyl, cadmium succinate, ethazole, thiophanate methyl, and thiram treatments. Earthworms fed bermudagrass clippings treated with 10 different fungicides showed a significant decrease in longevity from clippings treated with benomyl, dinocap, ethazole, and thiophanate methyl. Earthworms reared …
