Microhabitat Distribution And Its Effect Of Prey Utilization In Sympatric Populations Of Plethodon Glutinosus And Plethodon Dorsalis In Northwestern Arkansas, James M. Britton Jan 1981

Microhabitat Distribution And Its Effect Of Prey Utilization In Sympatric Populations Of Plethodon Glutinosus And Plethodon Dorsalis In Northwestern Arkansas, James M. Britton

Journal of the Arkansas Academy of Science

A study was done on sympatric populations of Plethodon glutinosus and P. dorsalis in northwestern Arkansas to determine the relative distribution of the two species and the relationship between their distribution and the utilization of available prey. Upon capture, total length, location, and habitat type were recorded for each salamander. Stomach content samples were obtained by forced regurgitation, and the animals were released. Samples of the local litter fauna were taken to determine prey availability. Habitat data were obtained for 171 salamanders; 76 P. glutinosus and 95 P. dorsalis. Stomach content samples were taken from 67 salamanders; 32 P. glutinosus …

Seasonal Abundance, Movement And Diversity Of Fishes In An Ozark Stream, Michael R. Dewey Jan 1981

Seasonal Abundance, Movement And Diversity Of Fishes In An Ozark Stream, Michael R. Dewey

Journal of the Arkansas Academy of Science

Seasonal fluctuations in fish abundance in Mud Creek occurred throughout the year at all sampling stations. At the two upper stations abundance was high and unstable during winter and early spring and decreased after heavy rainfall in mid-April. Abundance was low throughout the summer months, increasing in the fall due to large numbers of young-of-the-year. However, a different seasonal cycle occurred at the lower station which included deeper pools. Numbers were low and stable throughout the winter and early spring but high and unstable during the summer. Bigeye shiners (Notropis boops) and bluntnose minnows (Pimephales notatus) were the most mobile …

Preliminary Report On The Fishes Of The Upper Saline River, Polk And Howard Counties, Arkansas, And Observations On Their Relationships With Land Use And Physiochemical Conditions, Stephen A. Sewell Jan 1981

Preliminary Report On The Fishes Of The Upper Saline River, Polk And Howard Counties, Arkansas, And Observations On Their Relationships With Land Use And Physiochemical Conditions, Stephen A. Sewell

Journal of the Arkansas Academy of Science

The Saline River of southwest Arkansas was impounded by Dierks Lake in 1975. Intensive collecting efforts were made in the river system above Dierks Lake during March, April, and May 1980. Collected specimens were compared with ichthyofaunal lists prior to impoundment. Historic occurrants which were not collected include Notropis amnis, Notropis ortenburgeri, Moxostoma duquesnei, Ammocrypta vivax, and Percina copelandi. Additions to the ichthyofaunal list for the drainage include Fundulus notatus, Etheostoma spectabile, and Percina caprodes. The evidence indicates that 33 species representing six families inhabit the system from the headwaters in Polk County, Arkansas, to Dierks Lake, Howard County, Arkansas. …

Food Of Bluegill And Longear Sunfish In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen

Journal of the Arkansas Academy of Science

Stomach contents were examined from 544 bluegill (Lepomis macrochirus) and 709 longear sunfish (L. megalotis) collected from nearshore areas of DeGray Reservoir April-November 1976. Major foods of bluegill (percentage of total weight of food in parentheses) were insects (33), bryozoa (7.3), planktonic crustaceans (6.5), and plant materials (15.4). The major food items contributing to the diet of longear sunfish were insects (52.6%), crayfish (12.5%), fish (7.4%), and plant material (6.7%). Although bluegill and longear sunfish are closely related species, their diets were not as similar as expected: bluegill consumed zooplankton, adult dipterans, and adult ephemeropterans associated with limnetic areas; while …

Food Of Largemouth Bass (Micropterus Salmoides) In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen Jan 1980

Food Of Largemouth Bass (Micropterus Salmoides) In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen

Journal of the Arkansas Academy of Science

Stomach contents were examined from 748 largemouth bass, Micropterus salmoides (<125 mm total length), collected from DeGray Reservoir during April-November 1976. Fish constituted 59% by weight of the total diet and occurred in 81% of the stomachs; crayfish made up nearly 38% of the weight and occurred in 24% of the stomachs. Sunfish, the principal fish food (about 28% by weight), were observed in 36% of the stomachs. Shad were the second most important prey (23% by weight and 29% frequency in occurrence). Crayfish constituted about 42% of the total weight of the food of bass 200 mm long or longer, but only 12% in bass less than 200 mm. Crayfish consumption was greatest during the fall.

Inventory Of The Decapod Crustaceans (Crayfishes And Shrimps) Of Arkansas With A Discussion Of Their Habitats, Raymond W. Bouchard, Henry W. Robison Jan 1980

Inventory Of The Decapod Crustaceans (Crayfishes And Shrimps) Of Arkansas With A Discussion Of Their Habitats, Raymond W. Bouchard, Henry W. Robison

Journal of the Arkansas Academy of Science

The freshwater decapod crustaceans of Arkansas presently consist of two species of shrimps and 51 taxa of crayfishes divided into 47 species and four subspecies. The shrimps are represented by Macrobranchium ohione and Palaemonetes kadiakensis. The crayfish fauna is the largest of any state west of the Mississippi River reflecting the variety of habitats within Arkansas as a result of the geologic diversity in the state. The Ozark Plateaus and Ouachita provinces are dominated by the genus Orconectes, while in the Gulf Coastal Plain Procambarus is the most conspicuous group. Other crayfish stocks present include Cambarus, found predominantly in the …

Estimated Growth And Standing Crop Of Largemouth Bass (Micropterus Salmoides) From Lake Elmdale, Alex Zdinak Jr., Raj V. Kilambi, Marvin L. Galloway, John E. Mcclanahan, Clark Duffe

Journal of the Arkansas Academy of Science

Electro-fishing gear was used to make shoreline population estimates of largemouth bass (Micropterus salmoldes) in Lake Elmdale, Washington County, Arkansas, during September 1979. The population density was estimated to be 1541 bass/Km² with a standing crop of 30.4 kg/ha. The length-weight relationship was calculated as W = 0.00001 504L^2.97, and the total length-scale radius relationship as L = 41.75 + 1.23 St. The average condition coefficient(K) was 1.31. In comparison with four other Arkansas lakes the population density of largemouth bass was highest in Lake Elmdale while the growth rate was lowest.

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 …

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 …

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 …
