Notes On The Natural History Of Lasiurus Borealis In Arkansas, David A. Saugey, Robin L. Vaughn, Betty G. Crump, Gary A. Heidt

Journal of the Arkansas Academy of Science

Since June 1982 we have studied various aspects of red bat ecology in Arkansas with emphasis on field work in the Ouachita Mountains and examination of specimens submitted to the Arkansas Department of Health Rabies Laboratory (ADHRL).This study reports on continued field work in the Ouachita Mountains using radiotelemetry and updates information regarding red bats submitted to the ADHRL through December 1996. In addition, we revisited a cave previously reported to contain a large number of red bat skull and skeletal remains. We also report remains from another cave system in northcentral Arkansas. These investigations have yielded additional information on …

Mud Creek Urban Nonpoint Source Demonstration, Paul Vendrell, K. Teague Jan 1998

Mud Creek Urban Nonpoint Source Demonstration, Paul Vendrell, K. Teague

Arkansas Water Resources Center Technical Reports

Northwest Arkansas is the seventh fastest developing area in the nation. The conversion of rolling pastureland into paved city streets, parking lots, and buildings within this rapidly urbanizing region is reducing infiltration and intensifying stormwater runoff. In the city of Fayetteville alone, the population increased from 42,099 to 58,163 between 1990 and 1999, moving the city across the population threshold which will require the Phase II Stormwater Permit process. Approximately half of Fayetteville is included in the Illinois River Watershed, which has been identified as the third highest priority watershed in need of restoration in the state of Arkansas. Mud …

Highland Pond Utilization By Bats In The Ozark National Forest, Arkansas, J. D. Wilhide, Michael J. Harvey, V. Rick Mcdaniel, Vernon E. Hoffman

Journal of the Arkansas Academy of Science

During May through August 1996, wildlife ponds (man-made and/or naturally occurring) and road ruts on the Sylamore Ranger District, Ozark National Forest, Arkansas, were mist netted to determine extent of utilization by bats. Thirty-nine ponds and road ruts were netted one or more times during 53 nights. These water sources were originally constructed to support wildlife species such as deer, turkey, etc.. This study demonstrates that taxonomically and numerically diverse bat populations use these water sources. Seven hundred and seventy bats of nine species, including two endangered species, were netted. Bats were identified, and sex, reproductive status, forearm length, and …

Quantifying Community Separation And Increase In Number Of Avian Species With Corresponding Increase In Habitat Complexity, An African Example, Douglas A. James Jan 1998

Quantifying Community Separation And Increase In Number Of Avian Species With Corresponding Increase In Habitat Complexity, An African Example, Douglas A. James

Journal of the Arkansas Academy of Science

The relationship between increase in faunal diversity and corresponding increase in habitat complexity was quantified using shrubland bird communities in western Africa. Vegetational characteristics were measured in circular plots around bird positions. Bird species were then arranged from grassy open habitats to dense shrubland and found to be separated into three distinct communities when subjected to Duncan's multiple range procedure in conjunction with discriminant functions analysis. Random samples classified with respect to bird species showed there were few species in the more abundant open habitats and a disproportionate number of species were packed into the less common but complex shrubby …

Wood Frog (Rana Sylvatica) Use Of Wildlife Ponds In Northcentral Arkansas, Michael E. Cartwright, Stanley E. Trauth, J. D. Wilhide Jan 1998

Wood Frog (Rana Sylvatica) Use Of Wildlife Ponds In Northcentral Arkansas, Michael E. Cartwright, Stanley E. Trauth, J. D. Wilhide

Journal of the Arkansas Academy of Science

Forty-one wildlife ponds were monitored between 1988 and 1992 for breeding use by wood frogs (Rana sylvatica). Data were collected on egg deposition and pond characteristics. Breeding activity and characteristics were similar to that reported in other portions of the range of the wood frog. We also monitored 15 newly-constructed ponds to determine chronological breeding patterns. Data collected for each site indicated a significant increase (P< 0.05) in the number of egg masses deposited in ponds as they age from 1-3 years during our study period. Increased chronological use of newly-constructed ponds may be due to localized population increase resulting from greater availability of breeding habitat

In-Stream Monitoring Of Sediments And Water In The Lower Ouachita River For Site Impact To Aquatic Biota, Jerry L. Farris, J. T. Knight, C. D. Milam, F. Buzen, J. F. Nix Jan 1998

In-Stream Monitoring Of Sediments And Water In The Lower Ouachita River For Site Impact To Aquatic Biota, Jerry L. Farris, J. T. Knight, C. D. Milam, F. Buzen, J. F. Nix

Journal of the Arkansas Academy of Science

Reported reduced sportfish densities in the main channel of the Ouachita River prompted an investigation, beginning in 1990, into potential causes of ongoing impairment to aquatic biota. In-stream monitoring that incorporated toxicity testing of sediments and water was conducted to discern potential sources of contaminants that might be related to the suboptimal fishery populations. Organisms selected to evaluate chronic impairment included larval fish, clams, midges and water fleas. The fathead minnow {Pimephales promelas) and cladoceran (Ceriodaphnia dubid) were used to estimate patterns of toxicity associated with water from seven designated reaches and selected tributaries of the Ouachita River. Larval survival …

In Vitro Growth Characteristics Of Two Cryptococcus Neoformans Isolates, Kristy L. Jones, Juneann W. Murphy Jan 1998

In Vitro Growth Characteristics Of Two Cryptococcus Neoformans Isolates, Kristy L. Jones, Juneann W. Murphy

Journal of the Arkansas Academy of Science

Cryptococcus neoformans is an opportunistic pathogen which attacks individuals with weakened immune systems. Two C. neoformans isolates, 184A and NU-2, were examined to determine characteristics that contribute to their difference in virulence. Both isolates were grown under tissue culture conditions, and different characteristics were tested at timed intervals. Isolate 184A was found to grow at a faster rate than isolate NU-2, with doubling times of 4 and 12 hours respectively. The polysaccharide capsule of isolate NU-2 doubled in size in four hours, while that of isolate 184A stayed approximately the same. The NU-2 yeast cell diameter without the polysaccharide capsule …

Telemetric Observations Of Foraging Ozark Big-Eared Bats In Arkansas, J. D. Wilhide, V. Rick Mcdaniel, Michael J. Harvey, Daniel R. White Jan 1998

Telemetric Observations Of Foraging Ozark Big-Eared Bats In Arkansas, J. D. Wilhide, V. Rick Mcdaniel, Michael J. Harvey, Daniel R. White

Journal of the Arkansas Academy of Science

Ozark big-eared bat (Corynorhinus townsendii ingens) foraging activities were studied during 1995 in Marion County, Arkansas. Adult bats were equipped with radiotransmitters and tracked during June and July. Foraging activities were generally within 1 kilometer (km) of the roost cave. Male bats ranged farther than females with the exception of one female that flew 2.5 km into a different watershed. Male big-eared bats and northern long-eared bats (Myotis septentrionalis) were also found within the maternity colony.

Skeletochronological Study Of Adult Spiny Softshell Turtles (Apalone Spinifera) From Northeastern Arkansas, Stanley E. Trauth, Hilary J. Worley

Journal of the Arkansas Academy of Science

Skeletochronological techniques were used to examine age and growth in adult spiny softshell turtles {Apalone spiniferd) from northeastern Arkansas. The diaphyseal region offemurs of 24 specimens (8 mars mars; 16 venus venus) was excised, decalcified in weak hydrochloric acid, and histologically prepared for light microscopy. Skeletal growth was determined from histosectioned bones by measuring femur diameters as well as by counting lines of arrested growth (LAGs) that appear between distinct periosteal layers (marks of skeletal growth =MSGs) laid down during a single growing season. Although significant positive correlations were found between carapace length (CL) and femur diameter in both males …

Fish Community Of Indian Bayou, A Coastal Plain Stream Of Remarkable Species Richness In The Lower White River Drainage Of Arkansas, Thomas M. Buchanan Jan 1997

Fish Community Of Indian Bayou, A Coastal Plain Stream Of Remarkable Species Richness In The Lower White River Drainage Of Arkansas, Thomas M. Buchanan

Journal of the Arkansas Academy of Science

It is increasingly important to identify unique aquatic ecosystems in the coastal plain lowlands of Arkansas, because of the extensive human-induced alteration of aquatic habitats and loss of fish diversity in that region. Indian Bayou, part of a small (103 km2 ), chute-fed drainage system off the lower White River in Monroe County, Arkansas, has a fish community that is unique among Delta streams in darter (Percidae) species richness. Twenty-five fish samples collected by seine and rotenone from the Indian Bayou drainage system over an 18-year period produced 62 fish species, including 13 darter species. The fish community at one …

Investigation Of The Statistical And Spatial Distributions Of Mercury Contaminated Fish, Surface Waters And Soils In Arkansas, H. D. Scott, J. M. Mckimmey Jan 1997

Investigation Of The Statistical And Spatial Distributions Of Mercury Contaminated Fish, Surface Waters And Soils In Arkansas, H. D. Scott, J. M. Mckimmey

Arkansas Water Resources Center Technical Reports

Mercury (Hg) contamination of fish is a widespread problem throughout much of the United States and the world (Louisiana WWW page, 1997). Levels ofHg in fish suffic1ent to exceed the FDA action level of 1 mg kg-1 have been found in many water bodies, including some in Arkansas and Louisiana. As a result of the serious public health ramifications for developing fetuses and for people that subsist on native fish, fish consumption advisories due to Hg contamination have been issued in 29 states. Contamination of surface water bodies by Hg results from deforestation, forest fires, fossil fuels, mining, natural emissions …
