Age And Huddling As Determinants Of Metabolic Rate In Grasshopper Mice (Onychomys Leucogaster), Meredith Bailey, Dennis A. Baeyens, Lana Mann
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 …
Mollusca Of The Illinois River, Arkansas, M. E. Gordon, Arthur V. Brown, L. Russert Kraemer
Mollusca Of The Illinois River, Arkansas, M. E. Gordon, Arthur V. Brown, L. Russert Kraemer
Journal of the Arkansas Academy of Science
The Illinois River is in the Ozark region of northwestern Arkansas and eastern Oklahoma. A survey of the Illinois River in Arkansas produced nine species and one morphological subspecies of gastropods, three species of sphaeriid clams, and 23 species of unionid mussels. Museum records resulted in another two species and an ecophenotype of the Unionidae. This represents the first published survey of molluscan species from the Illinois River in Arkansas.

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 …

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 …

Distributional Survey Of The Fishes Of Ten Mile Creek In Southeastern Arkansas, Carl D. Jeffers, Edmond J. Bacon Jr.
Journal of the Arkansas Academy of Science
A survey of the fishes of Ten Mile Creek was conducted during 1976 to 1979. The ichthyofauna of Ten Mile Creek is typical of lowland drainage systems in southeastern Arkansas. Fifty-three species representing 13 families and 23 genera were collected. Etheostoma parvipinne was locally abundant in the headwaters, and other vulnerable or rare species included Notropls maculatus, Fundulus notti, Fundulus chrysotus, Erimyzon sucetta, Moxostoma poecilurum, and Lepomis punctatus. Eight specimens of Notropis hubbsi were collected.
Status Of The Red-Cockaded Woodpecker At The Felsenthal National Wildlife Refuge In Arkansas, Douglas A. James, Fred L. Burnside Jr.
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 …
Abundance, Diversity And Distribution Of Benthic Macro-Invertebrates In The Flat Bayou Drainage Area, Jefferson County, Arkansas, John D. Rickett
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 …

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 …

Comparison Of The Lens Protein Profiles Of Three Species Of Ozark Salamanders, James M. Britton
Comparison Of The Lens Protein Profiles Of Three Species Of Ozark Salamanders, James M. Britton
Journal of the Arkansas Academy of Science
The vertebrate lens has a high protein content (35%), 80-90% of which is composed of the soluble, lens-specific structural proteins, the crystallins. The lens protein profiles of urodelan species have been found to be qualitatively distinct. On this basis the lens proteins have been proposed as a measure of true speciation in urodelans. This paper is the result of our effort to derive a technique for comparison of lens protein profiles on a purely qualitative basis without utilizing the complex methodology employed by previous workers. With this object in mind, the lens protein profiles of Plethodon glutinosus, Ambystoma annulatum, and …
Electrophoretic Analysis Of Blood Serum Proteins In Three Species Of Water Snakes (Genus Nerodia), Phyllis J. Garnett
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 …
Time Course Of Pr Of Uv-Induced Chromosomal Aberrations And Lethal Damage In S And G2 Xenopus Cells, Jan Payne, H. Gaston Griggs
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. …
Genic Variation In White-Tailed Deer From Arkansas, Phyllis K. Price, Michael E. Cartwright, Mitchell J. Rogers
Genic Variation In White-Tailed Deer From Arkansas, Phyllis K. Price, Michael E. Cartwright, Mitchell J. Rogers
Journal of the Arkansas Academy of Science
Liver and kidney samples of 33 white-tailed deer (Odocoileus virginianus) representing three populations in Arkansas were examined with horizontal starch gel electrophoresis. Of 17 loci examined, only PGM-1 and ES-2 exhibited polymorphism. Average individual heterozygosity, ranging from 2.3% to 4.7% with a mean of 3.1 %, was much lower than that reported for white-tailed deer in other parts of its range. The three populations examined in this study were highly similar based on Rogers' genetic similarity coefficient.
