Amphibian, Reptile, And Small Mammal Associates Of Ozark Pocket Gopher Habitat In Izard County, Arkansas, M. Connior, I. Guenther, Thomas S. Risch, Stanley E. Trauth
Journal of the Arkansas Academy of Science
We conducted a study of the amphibian, reptile, and small mammal community assemblage of Ozark pocket gopher (Geomys bursarius ozarkensis) habitat in north-central Arkansas. We used 2 methods to capture individuals: hand capture and drift fences. During the study, we captured and marked a total of 9 anuran, 4 salamander, 5 lizard, 3 turtle, 16 snake, and 8 small mammal species exclusive of pocket gophers. We found one hatchling three-toed box turtle (Terrapene carolina triunguis) and one rough earth snake (Virginia striatula) inside a pocket gopher burrow and mound, respectively. Additionally, we witnessed both eastern racers (Coluber constrictor) and eastern …
Distribution And Taxonomic Status Of Tarantulas In Arkansas(Theraphosidae: Aphonopelma), Michael D. Warriner
Distribution And Taxonomic Status Of Tarantulas In Arkansas(Theraphosidae: Aphonopelma), Michael D. Warriner
Journal of the Arkansas Academy of Science
The genus Aphonopelma (Theraphosidae) is marked by a dearth of distributional data and a problematic taxonomy. To develop occurrence information for the genus in Arkansas, I conducted a citizen-science based survey augmented by field work and examination of museum collections. Results of these efforts yielded a significant amount of data that enabled the construction of a county level map of Aphonopelma distribution in Arkansas; a resource hitherto unavailable. Three Aphonopelma species have been described as occurring in Arkansas: A. baergi, A. hentzi, and A. odelli. Specimens were collected from Arkansas and Oklahoma to evaluate taxonomic and historical issues concerning the …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The ability to control growth of Listeria monocytogenes on ready-to-eat poultry products with the antimicrobials nisin, malic acid, and grape seed extract incorporated into whey-protein coatings was evaluated. The antimicrobials were incorporated into the coating solution alone and in combinations. One gram pieces of turkey frankfurters were coated with the coating solutions and then inoculated with L. monocytogenes and stored at 4°C for 28 days. The inhibitory effect of the coatings on turkey frankfurter pieces was evaluated on d 0, 7, 14, 21, and 28. Coatings containing 2% malic acid, 3% malic acid, and the combination of nisin (6,000 IU/g) …

Impact Of Stressing A Pen Mate On Physiological Responses Of Growing Pigs, Brent Koonce, Elizabeth B. Kegley, Doug Galloway, Jason Apple
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Crossbred barrows and gilts (n = 36), weighing 16.59 ± 2.1 kg, were used to test the effects of stressing a pen mate on the physiological responses of growing pigs. Pigs were randomly allotted to 6 groups after stratifying according to gender, litter origin, and body weight. Dominance order was determined within each group, and 1 to 3 d prior to the stress treatment the most- and least-dominant pigs within a group were fitted with indwelling catheters in their vena cavas. Over 3 d, groups were either: 1) isolated from audile and visual contact with stressed pigs in a separate …
Earthworm Abundances In Endophyte-Infected Tall Fescue Pastures In Northwest Arkansas, Ashley Rashe, Mary C. Savin
Earthworm Abundances In Endophyte-Infected Tall Fescue Pastures In Northwest Arkansas, Ashley Rashe, Mary C. Savin
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The ecology of organisms that co-evolve within an ecosystem is likely to be distinct from that involving organisms recently introduced into an area. To better understand the relationship of earthworms with endophyte-infected tall fescue, earthworms in novel and toxic endophyte-infected tall fescue pastures were enumerated and identified as adults or juveniles. We hypothesized that differences in endophyte infection of the fescue would influence earthworm abundances. Earthworms in two toxic and two novel endophyte-infected tall fescue fields in Fayetteville, Ark., were sampled weekly from January through July 2007. Each type of endophyte-infected pasture was established in 1997 and 2003. Sampling was …

Insects Inhabiting The Burrows Of The Ozark Pocket Gopher In Arkansas, Peter W. Kovarik, Stephen W. Chordas Iii, H. Robison, P. Skelley, M. Connior, J. Fiene, G. Heidt
Journal of the Arkansas Academy of Science
Pocket gopher burrows provide a stable environment for a variety of inquilines; hence this mammal is regarded as a keystone species. Most of the arthropods inhabiting pocket gopher burrows are restricted to this microhabitat. As part of a planned state-wide biotic survey of insects inhabiting this unusual microhabitat, we have focused our initial sampling efforts on the Ozark pocket gopher (Geomys bursarius ozarkensis; Geomyidae). In 2004 and 2005, pitfall traps were established in pocket gopher burrows and in 2007 and 2008, nests and associated chambers were excavated. Retrieved samples contained scarab, histerid, and rove beetles, cave crickets and anthomyiid flies. …

Impact Of The Agricultural Sector On The Arkansas Economy In 2003, Jennie Popp, Nathan Kemper, Wayne Miller
AAES Research Reports and Research Bulletins
Agriculture and associated agricultural activities are major contributors to the Arkansas economy. Agriculture is defined as the sum of agricultural production and processing activities, unless otherwise specified, and includes crop and animal production and processing, agricultural support industries, forestry and forest products, and textile goods. Agriculture contributes to the economy through direct agricultural production and value-added processing, and also leads to economic activity in other parts of the economy.

Comparison Of Aquatic-Insect Habitat And Diversity Above And Below Road Crossings In Low-Order Streams, J. Wesley Neal, Nathan J. Harris, Sathyanand Kumaran, David A. Behler, Thomas J. Lang, Paul R. Port, Marcella Melandri, Benjamin G. Batten
Journal of the Arkansas Academy of Science
The effects of road crossings on fish communities have been extensively studied; yet little attention has been given to macroinvertebrate communities. This study evaluated physical stream characteristics, water quality, and aquatic-insect richness from above and below road crossings of low-order streams in the Ouachita National Forest in Arkansas. Fifteen road crossings were sampled during October and November 2005. Erosion was significantly higher below road crossings than above. Sites downstream of road crossings had significantly lower pH and significantly higher turbidity than sites upstream of road crossings. Despite differences in water quality and habitat, there was no apparent difference in aquatic-insect …
Habitat Factors Affecting Trap Success Of Swamp Rabbits In Southeastern Arkansas During A Flooding Event, Blair Smyth, Karen B. Vale, Robert E. Kissell Jr.
Habitat Factors Affecting Trap Success Of Swamp Rabbits In Southeastern Arkansas During A Flooding Event, Blair Smyth, Karen B. Vale, Robert E. Kissell Jr.
Journal of the Arkansas Academy of Science
Swamp rabbits (Sylvilagus aquaticus) are found in bottomland hardwood ecosystems that have canopy gaps dispersed throughout. During annual flooding of these ecosystems, swamp rabbits often are displaced to adjacent uplands or higher ground within the bottomlands. Trapping of swamp rabbits is reported to be best during times of flooding. We examined habitat characteristics at trap sites to identify the best suits of habitat characters to target when trapping for swamp rabbits during flooding conditions. We conducted trapping for swamp rabbits during a flooding event from 2 January 2007 to 3 February 2007. A total of 511 trap nights yielded 16 …

Distribution Of The Queen Snake (Regina Septemvittata) In Arkansas, Johnathan W. Stanley, Stanley E. Trauth
Journal of the Arkansas Academy of Science
We documented the distribution of the queen snake, Regina septemvittata, in northern Arkansas during the 2005 and 2006 activity seasons. Arkansas currently contains the only known disjunct population of this species west of the Mississippi River. Field work was conducted throughout the Boston Mountains of the Ozark Plateau to verify the presence of queen snakes from historic localities as well as to identify new localities containing these snakes. Seventeen individuals were found in the Mulberry River of Franklin and Johnson counties and the Illinois Bayou watershed of Pope County. Of these 17 snakes, 5 were kept as voucher specimens in …
Survey Of Nesting By Cliff Swallows (Petrochelidon Pyrrhonota) And Barn Swallows (Hirundo Rustica) At Highway Bridges In Southern Arkansas, C. Renn Tumlison
Survey Of Nesting By Cliff Swallows (Petrochelidon Pyrrhonota) And Barn Swallows (Hirundo Rustica) At Highway Bridges In Southern Arkansas, C. Renn Tumlison
Journal of the Arkansas Academy of Science
The Cliff Swallow (Petrochelidon pyrrhonota) and Bam Swallow (Hinmdo rustica) both are migratory species that, in Arkansas, were known to nest only in the northern part of the state until the mid to late 1900s. The construction of concrete bridges apparently provided suitable nesting structure for both species. I conducted a survey of bridges along highways in southern Arkansas to look for evidence of nesting by these species. Nests of CliffSwallows were found in AsWey, Bradley, Clark, Cleveland, Hempstead, Hot Spring, Howard, Lafayette, Lincoln, Little River, Miller, Nevada, Ouachita, Pike, Sevier, and Union Counties. Nests of Barn Swallows were more …

Recent Observations Of The Distribution Of Woodchucks (Marmota Monax) In Arkansas, C. Renn Tumlison, D. Blake Sasse, Todd Pennington, Nicole Freeman
Recent Observations Of The Distribution Of Woodchucks (Marmota Monax) In Arkansas, C. Renn Tumlison, D. Blake Sasse, Todd Pennington, Nicole Freeman
Journal of the Arkansas Academy of Science
During the last couple of decades, the distribution of the woodchuck (Marmota monax) appeared to be expanding southward in Arkansas (Tumlison et al. 2001). An increase in the frequency of new sightings led us to re-evaluate the present status of this species of squirrel in the state. The woodchuck is not easily confused with other mammals, therefore we sought records of sightings to update information about its distribution. Recent range expansion had been documented in southwestern Arkansas, so we placed notices in stores and advertised in local newspapers in that region to intensively seek new records of sightings from the …
Status Of Birds Newly Recorded In Arkansas Since 1985, Douglas A. James, Joseph C. Neal, Max Parker, Charles Mills
Status Of Birds Newly Recorded In Arkansas Since 1985, Douglas A. James, Joseph C. Neal, Max Parker, Charles Mills
Journal of the Arkansas Academy of Science
In 1994 we published an annotated list of 14 bird species that were newly discovered in Arkansas since the publication in 1986 of the monograph "Arkansas Birds, Their Distribution and Abundance." We now add 22 more new species found in Arkansas since the 1994 publication, and update the status of the original 14. Adding these 36 species to the number included in "Arkansas Birds" totals 402 bird species currently reported in Arkansas.

Non-Invasive Technique For Assessing The Population Parameters Of Metacercariae Of Clinostomum Marginatum In Smallmouth Bass(Micropterus Dolomieu), James J. Daly Sr., Randal J. Keller, Bruce Deyoung
Journal of the Arkansas Academy of Science
Clinostomllm marginatum is a trematode that uses a fish as its final intennediate host. The wonns in the fish are in metacercarial cysts and are known as yellow grub. Yellow grubs give the fish's flesh a wonny, unappetizing appearance and are a problem for commercial fish fanners in that heavily infected fish are not suitable for marketing. The parasite is common in smallmouth bass (Micropterus dolomieu) living in upland streams of Arkansas where the bass may serve as a wild reservoir for contamination of commercial fish ponds. Because smallmouth bass are a prized game fish, it would be desirable to …
