Fishes Of The Strawberry River System Of Northcentral Arkansas, Henry W. Robison, John K. Beadles Jan 1974

Fishes Of The Strawberry River System Of Northcentral Arkansas, Henry W. Robison, John K. Beadles

Journal of the Arkansas Academy of Science

A survey of the fishes of the Strawberry River in northcentral Arkansas was made between August 1967 and November 1973. Field collections, literature records and museum specimens showed the ichthyofauna of the Strawberry River to be made up of 95 species distributed among 17 families. Two erroneous records are deleted. One subspecies, Etheostoma spectabile fragi,, is endemic to the river. Records of Notropis fumeus, Etheostotna nigrum, Etheostoma proeliare and Percina sciera represent extensions of previously known ranges within the state.

Ichthyofaunal Diversification And Distribution In The Ozark Stream In Northcentral Arkansas, William Dale Jackson, George L. Harp Jan 1973

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 …

Limnology Of Four Bauxite Open-Pit Lakes, George L. Harp, Ronald D. Hubbard Jan 1972

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 Jan 1972

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 Jan 1972

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 Jan 1972

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 …

Studies Of Arundinaria: Experimental Induction Of Flowering And Additional Observation In The Field, Daniel L. Marsh Jan 1971

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.

Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp Jan 1971

Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp

Journal of the Arkansas Academy of Science

A study of pre-impoundment limnological characteristics of the Strawberry River was made from August, 1967 to June, 1968. Two collecting stations were established, one upstream which would not be inundated and a lower station which would be inundated when impoundment was complete. The Strawberry River was characterized by high alkalinity and pH, low carbon dioxide and turbidity, and adequate oxygen values. Plankton was characterized by limited numbers of Staurastrum, Gomphonema, and Rotatoria. Pool-riffle communities were ill-defined. Chironomidae, Oligochaeta and Ephemeroptera were dominant pool macroinvertebrates among 13 taxa collected. Of the 20 taxa collected in riffles Trichoptera, Ephemeroptera, Simuliidae and Chironomidae …

Ichthyofaunal Diversification And Distribution In The Big Creek Watershed, Craighead And Greene Counties, Arkansas, James T. Jenkins, George L. Harp Jan 1971

Ichthyofaunal Diversification And Distribution In The Big Creek Watershed, Craighead And Greene Counties, Arkansas, James T. Jenkins, George L. Harp

Journal of the Arkansas Academy of Science

Big Creek is a relatively small deltaic stream, in northeastern Arkansas, in an area of intense cultivation. Recently it has been dredged in the interest of flood control. Lost Creek and Mud Creek are the major tributaries of Big Creek and collectively drain the Big Creek watershed. The streams were found to have relatively low alkalinity, moderate carbon dioxide, adequate oxygen values, and relatively high turbidity. Channeling of Big Creek and Lost Creek has effectively destroyed distinct pool-riffle biocies and reduced the number of acceptable spawning areas. Lost Creek, also, receives effluent from residential dwellings, a secondary treatment sewage plant, …

Effect Of Domestic Effluent On Two Spring Surveys Of Fishes In Lost Creek, Craighead County, Arkansas, John K. Beadles Jan 1970

Effect Of Domestic Effluent On Two Spring Surveys Of Fishes In Lost Creek, Craighead County, Arkansas, John K. Beadles

Journal of the Arkansas Academy of Science

Lost Creek is representative of deltonic streams of the St. Francis Basin possessing characteristics of being turbid. It has a low flow velocity except during the annual spring rains. Lost Creek meanders approximately 18 km. before receiving effluents and empties into Big Creek approximately 4 km. west of Jonesboro, Arkansas. Five collecting stations were studied in 1966 while six stations were sampled in 1970. Some fishes have been found to tolerate moderate amounts of domestic effluents and it is probable that the two species Lepomis cyanellus and Ictalurus melas, collected within the effluents, were more resistant than the other species …
