Distribution, Habitat Preference, And Status Of The Ditch Fencing Crayfish, Faxonella Clypeata (Hay) (Decapoda: Cambaridae), In Arkansas, H. W. Robison, C. T. Mcallister
Journal of the Arkansas Academy of Science
The ditch fencing crayfish, Faxonella clypeata (Hay), is a common and widespread crayfish that inhabits roadside ditches, intermittent first-order streams, shallow sloughs with heavy vegetation, and edges of swamps in Arkansas. Between 1997-2012, we made 55 collections of F. clypeata in 34 counties throughout eastern Arkansas, including 23 counties where F. clypeata had not been previously documented. At most of these locations within the West Gulf Coastal and Mississippi Alluvial Plain provinces, F. clypeata was found to be a locally abundant crayfish. With regard to conservation status, F. clypeata should be considered as “Currently Stable” due to its widespread distribution …

Growth And Reproduction In The Ouachita Madtom (Noturus Lachneri) At The Periphery Of Its Distribution, R. Tumilson, J. O. Hardage
Journal of the Arkansas Academy of Science
The Ouachita madtom (Noturus lachneri) occurs primarily in drainages of the upper Saline River and in a few small tributaries to the Ouachita River in Arkansas, USA. We collected specimens by hand and by use of aquarium dipnets on 29 occasions from 20 October 1999 through 25 July 2000 in Cooper Creek, presently a feeder creek into Lake Catherine on the Ouachita River. Total length was measured, reproductive attributes were noted, and individuals were released at the capture site (with exception of 3 gravid females retained to assess fecundity). We recognized 2 age (size) classes during most of the year …

Ecology Of The Squirrel Treefrog (Hyla Squirella) In Southern Arkansas, M. B. Connior, T. Fulmer, C. T. Mcallister, S. E. Trauth, C. R. Bursey
Journal of the Arkansas Academy of Science
We conducted an ecological study of the Squirrel Treefrog, Hyla squirella near El Dorado, Union Co., Arkansas from May-Oct. 2013. We extended the known distribution by ~2 km and documented the first breeding occurring on 28 May and the first transformation of juveniles on 27 Aug. Three endoparasites were documented: Opalina sp., Nyctotherus cordiformis, and Physaloptera sp. larvae. We also provide information on endoparasites of Florida H. squirella as well as a summary of helminths of this frog.

Toad (Anura: Bufonidae) Limb Abnormalities From An Aquatic Site In Scott, Pulaski County, Arkansas, C. S. Thigpen, D. Beard, S. E. Trauth
Journal of the Arkansas Academy of Science
We collected and examined 16 Fowler’s toads, Anaxyrus fowleri, and one dwarf American toad, Anaxyrus americanus charlesmithi, in central Arkansas in 2011. Collection was initiated by observation of abnormal toads. Toads were euthanized, measured, photographed, and deposited in the Arkansas State University herpetological collection. Several toads were radiographed. We found various abnormalities in both forelimbs and hindlimbs and on both sides of the body. The causes of the abnormalities remain unknown and will require further studies to determine if the environment is imperiled.
Eastern Spotted Skunk (Spilogale Putorius) At The Ouachita Mountains Biological Station, Polk County, Arkansas, L. M. Hardy
Eastern Spotted Skunk (Spilogale Putorius) At The Ouachita Mountains Biological Station, Polk County, Arkansas, L. M. Hardy
Journal of the Arkansas Academy of Science
A population of the eastern spotted skunk (Spilogale putorius) has been discovered at the Ouachita Mountains Biological Station in the Ouachita Mountains of Polk County, Arkansas. In 2010 a motion camera recorded a very brief infrared video of an animal that, after much study and conversation with other biologists, was concluded to be an eastern spotted skunk. Since that time the identification has been confirmed with at least 6 still photographs and one additional video that have been obtained from 2 other locations on the station. At least 2 or 3 individuals are present. All were photographed at night in …

Perch-Type Characteristics Of Overwintering Red-Tailed Hawks (Buteo Jamaicensis) And American Kestrels (Falco Sparverius), A. J. Worm, M. M. Bobowski, Thomas S. Risch
Journal of the Arkansas Academy of Science
Red-tailed Hawks (Buteo jamaicensis) and American Kestrels (Falco sparverius) are primarily sitand-wait predators that rely on perches to forage most efficiently. Overwintering Red-tailed Hawks and American Kestrels use available perches (e.g., utility poles and wires, trees, fences, gates, etc.) to hunt for prey items in agricultural fields in northeast Arkansas. Observations were made from December 2011-March 2012 and November 2012-March 2013 in three representative cover-types (short rice stubble, soybean stubble, and fallow areas including roadsides) to determine which perch-types were used by Red-tailed Hawks and American Kestrels. Utility pole crossbeams at an average height of 6.3 m were the main …

Status, Dispersal, And Breeding Biology Of The Exotic Eurasian Collared-Dove (Streptopelia Decaocto) In Arkansas, J. M. Fielder, R. Kannan, D. A. James, J. Cunningham
Journal of the Arkansas Academy of Science
The exotic Eurasian Collared-Dove (Streptopelia decaocto) was first sighted in Arkansas at Harrison (Boone Co.) on 25 June 1989. Since this initial sighting the species has grown in numbers and is now present in 42 of 75 counties across the state. In the spring and summer of 2009 and 2010, 20 nests were observed in the urban areas of Fort Smith (Sebastian County). Fifteen of the 20 nests (75%) were located on human-made structures of which 13 (65%) were on an electrical substation and two (10%) were on utility poles. The remaining 5 nests (25%) were in trees. Mean nest …
Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe
Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe
Journal of the Arkansas Academy of Science
As thermal infrared imaging technology has improved, it has increasingly been used for estimating sizes of wildlife populations. The greatest bias of thermal infrared surveys is the lack of known detection rates to adjust for visibility bias. As with visual surveys, a measure of detection rate is needed to provide unbiased estimates. We assessed the detection rate of white-tailed deer (Odocoileus virginianus) using a thermal infrared sensor (1.2 - 5.9 /an) from an aerial platform. Similar characteristics between thermal signatures of people and deer allowed us to use people in a reclined or horizontal position as surrogates for deer. We …
Effects Of Varied Intensity Resistance Training In Combination With Extra Mass-Bearing Exercise On Bone Adaptations In Ovariectomized And Sham Operated Sprague Dawley Rats, Donna Quimby, Kathy Hall
Effects Of Varied Intensity Resistance Training In Combination With Extra Mass-Bearing Exercise On Bone Adaptations In Ovariectomized And Sham Operated Sprague Dawley Rats, Donna Quimby, Kathy Hall
Journal of the Arkansas Academy of Science
This experiment was designed to study the effects of intensity of exercise on bone adaptations in ovariectomized and sham operated 12 week old rats. Eighty Sprague Dawley rats were divided by mass into two equal groups (mean = 197 g). One group was ovariectomized (OVX); the other sham (S) operated. Each surgery group was then subdivided by mass into four exercise intensity groups. The exercise intensity groups were created by loading additional mass (percent of animals body mass, 0%, 3%, 6% and 9%) on each animal in combination with treadmill running (10 m/min.; 30 min./day; 4 days/wk.; for 7 weeks). …

Cavity Protection Techniques For Red-Cockaded Woodpeckers, Warren G. Montague
Cavity Protection Techniques For Red-Cockaded Woodpeckers, Warren G. Montague
Journal of the Arkansas Academy of Science
Population growth of red-cockaded woodpeckers (Picoides borealis) is often limited by the availability of suitable cavities. Structural damage to natural and artificial cavities intended for use by P. borealis is common. Roost and nest cavities of P. borealis often become occupied by other cavity-dependent species. Techniques for preventing damage to artificial cavities and for deterring southern flying squirrel (Glaucomys volans) use of otherwise serviceable cavities are described. Such cavity protection techniques may be necessary to prevent extirpation of small, isolated populations of P. borealis.

Unhatched Eggs In Nests Of Red-Cockaded Woodpeckers, Warren G. Montague, Claudia F. Bailey, Joseph C. Neal, Douglas A. James
Journal of the Arkansas Academy of Science
During 1991 and 1992, nests of Red-cockaded Woodpeckers (Picoides borealis) were monitored in the Ouachita National Forest in Scott and Polk counties of west-central Arkansas. Nests in three additional woodpecker areas in Arkansas and Oklahoma were also monitored in 1992. Of 92 eggs laid in 27 nesting attempts in the Ouachita National Forest, 18 (19%) failed to hatch. When viewed in the cavities, six unhatched eggs were noticeably below average in size for the species and eight were average size. Seven unhatched eggs were removed in 1992 from seven nests in Arkansas and Oklahoma; three eggs showed some embryological development …
