Checklist Of Arkansas Fishes, Thomas M. Buchanan
Checklist Of Arkansas Fishes, Thomas M. Buchanan
Journal of the Arkansas Academy of Science
Arkansas has a large, diverse fish fauna consisting of 193 species known to have been collected from the state's waters. The checklist is an up-to-date listing of both native and introduced species, and is intended to correct some of the longstanding and more recent erroneous Arkansas records.
Natural Areas And Reference Collections For Environmental Education In Some Arkansas Schools, Jewel E. Moore
Natural Areas And Reference Collections For Environmental Education In Some Arkansas Schools, Jewel E. Moore
Journal of the Arkansas Academy of Science
A survey of 20 school campuses throughout Arkansas showed that most lack natural areas for outdoor environmental education. For most Arkansas schools no checklists of local plants are available, and there are no reference collections at the schools. Projects are underway at State College of Arkansas to establish herberia for the woody plants of Arkansas and the vascular plants of Faulkner County.

Status Of The Mountain Lion In Arkansas, John A. Sealander, Philip S. Gipson
Journal of the Arkansas Academy of Science
Two authenticated kill records of the mountain lion, Felis concolor, in Arkansas are reported as well as numerous reliable sight records spanning an approximately 30-year period. Distribution of sightings in the state is discussed in relation to an expanding deer population. The cougar probably never was exterminated in Arkansas but it still may be considered endangered.
Ichthyofaunal Diversification And Distribution In The Ozark Stream In Northcentral Arkansas, William Dale Jackson, George L. Harp
Ichthyofaunal Diversification And Distribution In The Ozark Stream In Northcentral Arkansas, William Dale Jackson, George L. Harp
Journal of the Arkansas Academy of Science
The distribution and diversity of the ichthyofauna of Arkansas are poorly known. This study is part of a continuing effort to elucidate the natural history of Arkansas. Big Creek is a relatively small, clear, cool-water stream in the Ozark Plateau of northcentral Arkansas. Big Creek and its tributaries drain into Lake Norfork, an impoundment on North Fork River. A total of 6,779 fish of 30 species was collected. Dominant pool species included Notropis boops, Fundulus catenatus, F. olivaceus, Labidesthes sicculus, and Campostoma anomalum; dominant riffle species included Etheostoma spectabile, E. caeruleum, Notropis boops, Fundulus catenatus, and Campostoma anomalum. The numerical …
Respiration Rates Of Two Midge Species At Different Temperatures, George L. Harp, Robert S. Campbell
Respiration Rates Of Two Midge Species At Different Temperatures, George L. Harp, Robert S. Campbell
Journal of the Arkansas Academy of Science
Respiration values for Chironomus n. sp. ranged from 0.11 mm³ O₂ /mg/hr at 5C to 0.44 mm³ O₂. /gm/hr at 25C. The range for Chaoborus punctipennis was from 0.15 mm³ O₂ /mg/hr at 5C to 0.56 mm³ O₂ /mg/hr at 25C. These low respiratory rates allow the two species to withstand low oxygen tensions for extended periods of time. Reflecting this ability, both species attained their greatest numerical and biomass values in the profundal regions of three strip-mine lakes whose lower waters become oxygen depleted during thermal stratification.
A Survey Of The Fishes Of The Mulberry River, Arkansas, Larry L. Olmsted, Gary D. Hickman, Donald G. Cloutman
A Survey Of The Fishes Of The Mulberry River, Arkansas, Larry L. Olmsted, Gary D. Hickman, Donald G. Cloutman
Arkansas Water Resources Center Technical Reports
Announcement of plans to dam Mulberry River, Arkansas, by the United States Army Corps of Engineers has generated some dispute. Most agruments against damming the stream revolve around environmental degradation and loss of aesthetic values. This report serves as a pre-impoundment survey of the fishes of the Mulberry River so that possible effects of impoundment can be more objectively assessed. Knowledge on the fishes of the Mulberry River is severely lacking. The first study was by Jordan and Gilbert (1886) who collected in the southern U.S. in July, August, and September, 1884. They collected in many streams in Arkansas including …
Anatomical And Behavioral Aspects Of Killing And Feeding By The Least Weasel, Mustela Nivalis L., Gary A. Heidt
Anatomical And Behavioral Aspects Of Killing And Feeding By The Least Weasel, Mustela Nivalis L., Gary A. Heidt
Journal of the Arkansas Academy of Science
The least weasel (Mustela nivalis) is a remarkably well adapted predator of mice and other small animals. Each kill is rather stereotyped, in that the weasel grabs the prey by the nape of the neck and bites through the base of the skull and/or throat, using its lithe body to "wrap up" and hold the prey. The least weasel will kill mice successively until it is too exhausted physically to kill more. Mice are always eaten from the head posteriorly until completely consumed.

Limnology Of Four Bauxite Open-Pit Lakes, George L. Harp, Ronald D. Hubbard
Limnology Of Four Bauxite Open-Pit Lakes, George L. Harp, Ronald D. Hubbard
Journal of the Arkansas Academy of Science
The aquatic flora and fauna and 18 physicochemical characteristics of four bauxite open-pit lakes were studied from September 1969 to August 1970. The least acid lake (pH 3.4-4.4) supported 49 different aquatic insects, plankton, and higher aquatic plants. The most acid lake (pH 2.7-3.2) supported only 26 different plants and animals. Bauxite open-pit lakes within the pH range studied appear to be as relatively unproductive as their coal strip-mine lake counterparts, with which they share physicochemical and biological characteristics. Benthic macrofaunal diversity and abundance appear to be related more closely to distribution and abundance of leaf detritus than to hydrogen-ion …

Some Physiochemical Parameters And Phytoplankton Standing Crop In Four Northeast Arkansas Commercial Fish Ponds, Haldor Marvin Wilkes, John K. Beadles
Some Physiochemical Parameters And Phytoplankton Standing Crop In Four Northeast Arkansas Commercial Fish Ponds, Haldor Marvin Wilkes, John K. Beadles
Journal of the Arkansas Academy of Science
Physicochemical conditions and chlorophyll a standing crop were studied from July 1970 through June 1971 in four commercial catfish ponds at the Arkansas State University Experiment Farm near Walcott, Greene County, Arkansas. Determinations of dissolved oxygen, free carbon dioxide, total alkalinity, temperature, pH, transparency, and chlorophyll a standing crop were made at two-week intervals except during fish harvesting operations. One diurnal measurement of dissolved oxygen, free carbon dioxide, and temperature was conducted 25-26 June 1971. Increased oxygen concentrations coincided with increased chlorophyll α concentrations. Free carbon dioxide and chlorophyll α values varied inversely throughout the study. Diurnal concentrations of free …
Failure To Establish Feral Coturnix Quail Populations In Arkansas In The Late 1950'S, Douglas A. James
Failure To Establish Feral Coturnix Quail Populations In Arkansas In The Late 1950'S, Douglas A. James
Journal of the Arkansas Academy of Science
Although Coturnix introductions failed in the late 1950's, it was learned in Arkansas that birds survived longest after autumn releases especially where fallow fields were numerous, that Coturnix favored grasslands whereas the bobwhite preferred shrublands, and that Coturnix occurred singly, pairing only in the breeding season.
Build-Up Of Ions In Areas Of Lake Dardenelle As Affected By Stream Flow, Tom N. Palko
Build-Up Of Ions In Areas Of Lake Dardenelle As Affected By Stream Flow, Tom N. Palko
Journal of the Arkansas Academy of Science
The poultry industry in the Lake Dardanelle watershed annually introduces large amounts of poultry effluents into the system. This, plus the large concentrations of chloride ions that are introduced into the lake from salt deposits in the upper Arkansas River watershed, has definite effect on the limnological conditions of the lake. The buildup of chloride ions in areas of the lake depends on the amount of flow from streams into these parts of the lake. This stagnation phenomenon is especially noticeable in pocket areas which are generally cut off from the major influence of the river as it flows in …

Various methods of collecting were used in an effort to sample all populations and to contribute to knowledge of the taxonomy both Mississippi and Arkansas.
Histological Study Of Liver On Channel Catfish, Ictalurus Punctatus, Leland F. Morgans
Histological Study Of Liver On Channel Catfish, Ictalurus Punctatus, Leland F. Morgans
Journal of the Arkansas Academy of Science
Histologically the liver of the channel catfish, Ictalurus punctatus, was found to consist of many lobules. Though not surrounded by a connective tissue sheath as they are in some animals, the lobules were discernable because all the hepatic cells in a particular area radiated from a central vein. Portal triads were scattered throughout the liver. The lobule tissue consisted of radiating cords of cells alternating with sinusoids. Glycogen was condensed into large vacuoles within these cells. Pancreatic tissue was found in the liver, always surrounding a capillary or venule. Morphologically the pancreatic cells were exocrine. Functionally, however, they may be …
A Study Of Phytoplankton Dynamics In Lake Fayetteville As A Means Of Assessing Water Quality, Richard L. Meyer
A Study Of Phytoplankton Dynamics In Lake Fayetteville As A Means Of Assessing Water Quality, Richard L. Meyer
Arkansas Water Resources Center Technical Reports
Phytoplankton community was analyzed for seasonal and vertical distribution in Lake Fayetteville. This northwest Arkansas reservoir maintains a stable water level and chemical input with a relatively constant, slow overflow. Its source is groundwater seepage through a calcareous substrate with little contribution from the limited drainage basin. Phytoplankton community development with its associations and assemblages, chlorophylls -a, -b and c, and biomass distribution are described. The seasonal cycles of the chemical parameters NH4-N, NO2-N, NO3-N, ortho-phosphate, silicon, pH, HCO3- and total-alkalinity plus oxygen are described and discussed. The physical parameters of temperature, light and climate are included. The interaction of …
Interim Report On Water Quality Investigation Degray Reservoir, Arkansas, J. Nix
Interim Report On Water Quality Investigation Degray Reservoir, Arkansas, J. Nix
Arkansas Water Resources Center Technical Reports
Impoundment of the Caddo River near Arkadelphia, Arkansas began in August, 1969. Detailed patterns of the dissolved oxygen distribution in this reservoir are presented for the period September, 1969 through April, 1971. Although the reservoir had not reached normal pool elevation, thermal stratification accompanied by severe hypolimnic oxygen depletion has been observed. The dissolved oxygen data show that an under flow occurs in the fall of the year and carries dissolved oxygen into the hypolimnic zone. The gradients of dissolved oxygen concentration observed during the winter indicate that the reservoir does not undergo complete mixing. A short summary of the …
Environmental Changes Produced By Cold-Water Outlets From Three Arkansas Reservoirs, Carl E. Hoffman, Raj V. Kilambi
Environmental Changes Produced By Cold-Water Outlets From Three Arkansas Reservoirs, Carl E. Hoffman, Raj V. Kilambi
Arkansas Water Resources Center Technical Reports
Water qualities of two natural streams (Buffalo and Kings Rivers), one new coId-tailwater (Beaver), and two old coId-tailwaters (Norfork and Bull Shoals) in northwestern Arkansas were studied from July 1965 through October 1968. The essential difference between the old cold-tailwaters and natural streams is a change in water quality which allows the development of a new productive ecological environment. Features which typify the old tailwaters are as follows: (1) relatively homioithermal temperatures; (2) stream beds scoured by strong hydoelectric power generation currents; (3) abundant phytoplankton and benthic macroinvertebrates; and (4) absence of warm water game fishes. Environmental factors characterizing natural …

Impoundment Effects On Water Quality As Reflected In Parasitism Of Reservoir Basses, David A. Becker
Impoundment Effects On Water Quality As Reflected In Parasitism Of Reservoir Basses, David A. Becker
Arkansas Water Resources Center Technical Reports
Our aquatic environments are rapidly becoming useless as natural resources through pollution from various sources. It is therefore necessary for us to further understand the various means which relate to this process. The interrelationships between the physico-chemical and biological water qualities undergo marked changes during the ageing of a reservoir. Eutrophication of these impoundments render them rela-tively useless as natural resources. It thus becomes apparent that we must gain further knowledge of these processes if we are to devise methods for proper reservoir management.

Consideration Of Macro-Climatic And Macro-Biotic Change In The Ozark Highlands During Post-Glacial Times, Kenneth W. Cole
Consideration Of Macro-Climatic And Macro-Biotic Change In The Ozark Highlands During Post-Glacial Times, Kenneth W. Cole
Journal of the Arkansas Academy of Science
Climatological, pedological and faunal investigations conducted in the Upper Midwest and the Ozark Highlands indicate that the environment to which man in the Ozarks was adapting over the past 12,000 years has undergone several major shifts, beginning with a cool-moist boreal forest situation followed by a period of warming and aridness resulting in prairie and deciduous forest climaxes and subsequently, in the last 4000-5000 years, change to the pattern reflected by present conditions.
Studies Of Arundinaria: Experimental Induction Of Flowering And Additional Observation In The Field, Daniel L. Marsh
Studies Of Arundinaria: Experimental Induction Of Flowering And Additional Observation In The Field, Daniel L. Marsh
Journal of the Arkansas Academy of Science
Arundinaria has been observed for three successive seasons at a site near Amity, Arkansas. In advance of the 1971 flowering period rhizomes were taken from the field, pruned, and placed either in an environmental chamber or in the greenhouse in water or in sandy soil. Flowering occurred under each condition, but was most rapid and profuse in transplants growing in sandy soil in the greenhouse. Observations point to the possibility of induction of flowering or to the possible existence of an annually flowering race. Possible economic uses are considered.
