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

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 …
Highland Pond Utilization By Bats In The Ozark National Forest, Arkansas, J. D. Wilhide, Michael J. Harvey, V. Rick Mcdaniel, Vernon E. Hoffman
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 …
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
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 …
Wood Frog (Rana Sylvatica) Use Of Wildlife Ponds In Northcentral Arkansas, Michael E. Cartwright, Stanley E. Trauth, J. D. Wilhide
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

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