Size Variation Of Ungraded And Graded Channel Catfish Reared In Cages, Donald C. Greenland, Walter R. Robison, Scott H. Newton Jan 1983

Size Variation Of Ungraded And Graded Channel Catfish Reared In Cages, Donald C. Greenland, Walter R. Robison, Scott H. Newton

Journal of the Arkansas Academy of Science

Graded and ungraded channel catfish (Ictalurus punctatus) fingerlings stocked in three partitioned floating cages were reared for 140 days during the summer, 1982. Fish were fed to satiation once daily with a commercial pelleted ration. At harvest, graded fish averaged 403 g and ungraded 362 g. Coefficients of variation indicated graded fish were more uniform in size and a significantly greater proportion of the graded fish were of salable size (> 340 g).

Mensural Discrimination Of The Skulls Of Arkansas Peromyscus, V. Rick Mcdaniel, C. Renn Tumlison, Phil Mclarty Jan 1983

Mensural Discrimination Of The Skulls Of Arkansas Peromyscus, V. Rick Mcdaniel, C. Renn Tumlison, Phil Mclarty

Journal of the Arkansas Academy of Science

Twelve parameters were measured on skulls of four species of Peromyscus from Arkansas. Univariate statistical tests, multivariate analyses of variance, and principal axis factor analyses were performed on the data set and/or subsets in a search for species-level discriminating characters. Total length of skull was found to discriminate between skulls of P. maniculatis, P. leucopus, and a combined group of P. attwateri and P. gossypinus. Furthermore, the ratio of interorbital width and length of nasal bone was found to adequately discriminate between skulls of P. attwateri and P. gossypinus.

Selection Of Scales For Growth Analysis Of Largemouth Bass, Donald C. Jackson, Raj V. Kilambi Jan 1983

Selection Of Scales For Growth Analysis Of Largemouth Bass, Donald C. Jackson, Raj V. Kilambi

Journal of the Arkansas Academy of Science

Scales from four regions of the body of largemouth bass were compared for efficacy in estimating fish length at the time of scale formation and at capture. The scales from above and below the lateral line in the pectoral and caudal peduncle regions yielded intercepts of 64.73, 52.36, 19.77 and 25.81 respectively for the total length-scale radius relationship. These intercept values represent the fish length at the time of scale formation. By the regression of estimated lengths at capture on empirical lengths it was found that the caudal peduncle scales were better suited in predicting fish length.

Success Of Wild-Trapped Compared To Captivity-Raised Birds In Restoring Wild Turkey Populations To Northwestern Arkansas, Douglas A. James, L. Glen Fooks, John R. Preston Jan 1983

Success Of Wild-Trapped Compared To Captivity-Raised Birds In Restoring Wild Turkey Populations To Northwestern Arkansas, Douglas A. James, L. Glen Fooks, John R. Preston

Journal of the Arkansas Academy of Science

Reintroduction of wild turkeys into northwestern Arkansas was studied at 10 release sites in the late 1950's. Native birds trapped in southern Arkansas were released at five study areas, and birds from wild Pennsylvania stock reared in captivity were released in five other areas. Although both types of turkeys reproduced, most populations of captivity-raised turkeys decreased sharply whereas all populations of wild-trapped birds exhibited marked increases. Range extension averaged nearly 2.5 miles per year in expanding wild-trapped populations. Captivity-raised birds were comparatively tame and often were found near human habitation. Current expanding turkey populations in the Arkansas Ozarks undoubtedly are …

Comparison Of Two Year Classes Of Hybrid Grass Carp And Grass Carp For Aquatic Plant Control, Mike Freeze, Scott Henderson Jan 1983

Comparison Of Two Year Classes Of Hybrid Grass Carp And Grass Carp For Aquatic Plant Control, Mike Freeze, Scott Henderson

Journal of the Arkansas Academy of Science

Two year classes of grass carp and F, hybrids resulting from bighead carp male x grass carp female were compared at various stocking densities for aquatic plant control. One and two year old grass carp exhibited higher survival rates and better growth rates than the same age hybrid grass carp. The presence of grass carp or hybrid grass carp decreased both Secchi disc transparencies and dissolved oxygen values. Grass carp had a greater negative effect upon these measurements because they removed the vegetation quicker than the hybrid grass carp. These apparent detrimental effects on water quality are necessary trade-offs for …

Abundance And Seasonal Occurrence Of Psorophora Columbiae In A Northeast Arkansas Ricefield Community, Larry A. Olson, Julia A. Huggins Jan 1983

Abundance And Seasonal Occurrence Of Psorophora Columbiae In A Northeast Arkansas Ricefield Community, Larry A. Olson, Julia A. Huggins

Journal of the Arkansas Academy of Science

Increased population levels of the dark ricefield mosquito, Psorophora columbiae (Dyar and Knab), have been shown to be associated with rice cultivation in Arkansas and several other states. Four standard New Jersey light traps were operated daily between May 30 and October 2 of 1981 and 1982 to determine the relative abundance and seasonal occurrence of this species in NE Arkansas. The effect of trap distance from nearby rice on the number of adult P. columbiae collected was assessed by comparing weekly totals from 2 traps located within 0.9 km of rice fields with totals from 2 traps situated beyond …

Aquatic Macroinvertebrates Of Three Acid Bogs On Crowley's Ridge In Northeast Arkansas, Jerry L. Farris, George L. Harp Jan 1982

Aquatic Macroinvertebrates Of Three Acid Bogs On Crowley's Ridge In Northeast Arkansas, Jerry L. Farris, George L. Harp

Journal of the Arkansas Academy of Science

Qualities and quantities of parameters composing the bog systems in Northeast Arkansas are not entirely reflective of those defining bogs of the northern United States. While pH is restricting to the organisms of each bog studied (4.8-6.9), the major limiting factor is the amount of available water. Three acidophilic bogs with shallow water depths (2-30 cm) yielded a total of 75 aquatic macroinvertebrate taxa. The bog with greatest surface area supported 67 taxa and a mean numerical standing crop of 14 organisms/2 hr sampling period. The bog with the smallest surface area had 13 taxa and a mean standing crop …

Macroinvertebrate Utilization Of Leaf Detritus In A Riffle Of The Illinois River, Arkansas, Arthur V. Brown, Janet P. Ricker Jan 1982

Macroinvertebrate Utilization Of Leaf Detritus In A Riffle Of The Illinois River, Arkansas, Arthur V. Brown, Janet P. Ricker

Journal of the Arkansas Academy of Science

Small (5 g) leaf packs were placed in a shallow riffle area of the Illinois River in western Benton County, Arkansas, and sequentially retrieved after various exposure times during the winter and spring of 1980. Oak leaves (Quercus shumardii) were utilized more rapidly (9.2% remaining after 91 days), followed by oak/sycamore (Q. shumardii/Platanus occidentalis) leaf packs (31.8% remaining after 91 days). Sycamore {P. occidentalis) was the slowest processed type (32.2% remaining after 91 days). The initial colonization by shredders as characteristic of northern U S. streams did not occur in this study. Collector organisms were present in the leaf packs …

Wild Commercial Fishery Of Arkansas, Tommie Crawford, Mike Freeze Jan 1982

Wild Commercial Fishery Of Arkansas, Tommie Crawford, Mike Freeze

Journal of the Arkansas Academy of Science

Arkansas' wild commercial fishery industry was surveyed to evaluate commercial fish products produced within the state. The total wild commercial catch for the period of 1 July 1980 to 30 June 1981 was approximately 8,680,124 kg with a value of $6,245,967. These values represent an increase of approximately 3% from the previous year. The bulk of the commercial harvest was made up of buffalo fishes (Ictiobus spp.), catfishes (Ictalurus spp), gars (Lepisosteus spp.) and carp (Cyprinus carpio). The number of commercial fishermen remained relatively unchanged from 1979-1980, with 3,843 licensed fishermen operating on the state's waterways. The number of licensed …

Leaf Detritus Processing In An Ozark Cave Stream, Arthur V. Brown, Mark D. Schram Jan 1982

Leaf Detritus Processing In An Ozark Cave Stream, Arthur V. Brown, Mark D. Schram

Journal of the Arkansas Academy of Science

Detritus processing rates and mechanisms were investigated in an Ozark cave stream using post oak (Quercus stellata) leaf packs. The 5 g leaf packs lost ca. 30% of their dry weight within 84 days, resulting in a calculated K value of 0.05. This was an unexpectedly high rate of utilization. Diversity of invertebrates associated with the leaf packs was very low. Stygobromus ozarkensis (Amphipoda) was the only shredder. The two isopods, Caecidotea stiladactyla and Lirceus sp. were the only collectors observed other than a single species of oligochaete worm. Our data indicated that leaf detritus processing rates are virtually independent …

Soil Traversing Arthropod Populations As Sampled By Pitfall Traps In Sunflower And Three Adjacent Habitats In Northeast Arkansas, Linda A. Lee, Harvey E. Barton Jan 1982

Soil Traversing Arthropod Populations As Sampled By Pitfall Traps In Sunflower And Three Adjacent Habitats In Northeast Arkansas, Linda A. Lee, Harvey E. Barton

Journal of the Arkansas Academy of Science

Soil traversing arthropod populations were sampled by pitfall traps in sunflower (Helianthus spp.) and three adjacent habitats during the months of July, August and September of 1980 and May, June, July and August of 1981. In1980, four varieties of sunflower (Ellar, Hybrid 670, 891 and S-345) were planted. A single variety of sunflower (Ellar) was planted in1981. The three adjacent habitats in both 1980 and 1981 were a pine stand, grass border and fence row. Of 1,748 specimens collected in 1980, 17 orders and 48 families were represented. Four orders comprised 78% of the total catch: Hymenoptera (45%), Acari (17%), …

Effects Of Water Released From Stratified And Unstratified Reservoirs On The Downstream Water Quality, Stephen B. Smith Jan 1982

Effects Of Water Released From Stratified And Unstratified Reservoirs On The Downstream Water Quality, Stephen B. Smith

Journal of the Arkansas Academy of Science

Water quality samples were collected from the Little River system in Pine Creek Lake, Oklahoma, and Gillham Lake, Arkansas, and their associated tailwaters during the winter (reservoirs unstratified) and summer (reservoirs stratified) of 1980. Downstream water quality was not affected by reservoir water releases while the reservoirs were unstratified. When the reservoirs were stratified water quality in the tailwaters was dependent on the release depth of the water. The practice of flushing out a tailwater following an extended low flow period should be examined on a site by site basis. Anoxic water released from a reservoir may contain high amounts …

Invertebrate Fauna Of Devils Den, A Sandstone Cave In Northwestern Arkansas, Stewart B. Peck, James H. Peck Jan 1982

Invertebrate Fauna Of Devils Den, A Sandstone Cave In Northwestern Arkansas, Stewart B. Peck, James H. Peck

Journal of the Arkansas Academy of Science

The same invertebrate fauna of 17 species was found in Devils Den Cave, Washington County, Arkansas, in 1969 and 1979. The fauna consists of 1 trogloxene, 14 troglophiles, and 2 troglobites, a spider, Porrhomma cavernicolum, and a collembolan, Pseudosinella dubia. Devils Den Cave has a well developed cavernicolous fauna, although it is in sandstone which generally supports a poor cave adapted fauna. The troglobites probably evolved in the vicinity of northwestern Arkansas in limestone caves or in deep forest soils of the Ozark region. They then dispersed overland, perhaps as recently as the late Wisconsinan, to occupy this sandstone cave.
