Ants Of Arkansas Post National Memorial: How And Where Collected, David M. General, Lynne C. Thompson
Journal of the Arkansas Academy of Science
A knowledge of the fauna of natural areas is necessary for their sustainable management. Thus, intensive ant sampling over multiple years was conducted at Arkansas Post National Memorial in southeastern Arkansas. Our collecting techniques included: pitfalls; leaf litter sifting with Berlese extraction; breaking into twigs, branches, and coarse woody debris located on the ground; baiting tree trunks with peanut butter; and general hand collecting. Ants were collected from diverse habitats, including: open mowed-grass, mowed-grass under hardwood trees, unmowed tall-grass and weeds, and numerous forest types. A total of 43 species in 25 genera and 6 subfamilies were identified. The number …

Geographic Variation In The Pollination Biology Of Passiflora Lutea (Passifloraceae), J. Burks Holland, J. Lanza
Journal of the Arkansas Academy of Science
Like most species of Passiflora, P. lutea is reported to produce one-day flowers with complicated floral movements and requires deposition of non-self pollen for fruit production. Medium sized bees are the most likely pollinators in central Texas. We report on a series of observations and experimental manipulations that compare the reproductive biology of P. lutea in central Arkansas to that reported previously from plants about 800 km distant in central Texas. We observed floral movements and floral visitors, compared fruit production of flowers available to pollinators versus flowers from which pollinators were excluded, and compared fruit production of flowers that …
Algae In Agricultural Fields From St. Francis County, Arkansas, T. Smith
Algae In Agricultural Fields From St. Francis County, Arkansas, T. Smith
Journal of the Arkansas Academy of Science
On August 9th, 2007, two agriculture fields (rice and sorghum fields) were sampled for freshwater algae in St. Francis County. The purpose of this study was to document the algal species in the rice and sorghum fields and compare the similarities of species composition. There were a total of 53 species identified. Overall, diatoms and cyanobacteria were equally dominant with both represented by 21 species (39.6% of the total) and 11 green algal species (20.8%) were present. The sorghum field was dominated by Chlorogloeopsis fritschii and Chroococcus limneticus, while Anabeana cylindrica was abundant in the rice field.
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 …

Arkansas Endemic Biota: An Update With Additions And Deletions, H. Robison, C. Mcallister, C. Carlton, G. Tucker
Journal of the Arkansas Academy of Science
It has been over a decade since the publication of Robison and Allen (1995) that provided the definitive list of endemic flora and fauna of Arkansas. The present study brings up-to-date the endemic biota of the state. Since 1995, several new species have been described and new discoveries have been made, adding species to the state biota. Other species are deleted and new distributional information on other state endemics is presented. Specifically, 3 new plant species are added to the state list while 4 plant species are deleted. Sixteen new animal species/subspecies are added to the state list while numerous …

Comparison Of Pine Height Models For The Crossett Experimental Forest, Don C. Bragg
Comparison Of Pine Height Models For The Crossett Experimental Forest, Don C. Bragg
Journal of the Arkansas Academy of Science
Many models to predict tree height from diameter have been developed, but not all are equally useful. This study compared a set of height-diameter models for loblolly (Pinus taeda) and shortleaf (Pinus echinata) pines from Ashley County, Arkansas. Almost 560 trees ranging in diameter at breast height (DBH) from 0.3 cm (both species) to 91.9 cm (for shortleaf) or 108.2 cm (for loblolly) were chosen for measurement. Height equations were then fit to four different functions (Chapman-Richards, modified logistic, exponential, and Curtis-Arney) with weighted nonlinear least squares regression using DBH as the only predictor. Models were evaluated using a series …

Compatible Stem Taper And Total Tree Volume Equations For Loblolly Pine Plantations In Southeastern Arkansas, C. Vanderschaaf
Compatible Stem Taper And Total Tree Volume Equations For Loblolly Pine Plantations In Southeastern Arkansas, C. Vanderschaaf
Journal of the Arkansas Academy of Science
A system of equations was used to produce compatible outside-bark stem taper and total tree volume equations for loblolly pine (Pinus taeda L.) plantations in southeastern Arkansas. Paired height diameter stem measurements were obtained from trees located in one 45-year-old unthinned plantation. After fitting and integrating the stem taper equation to total tree height, an individual tree constant form factor volume equation was obtained. The stem taper equation can also be integrated to any merchantable height to obtain merchantable volume. To see how the constant form factor volume equation predicts outside bark volume for trees vastly different than those used …

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 …

Aquatic Macroinvertebrates Collected From Thirty-Two Missouri Ozark Streams, George L. Harp, Phoebe A. Harp, Samuel B. Mccord
Journal of the Arkansas Academy of Science
A previously reported study of the distribution and status of an endemic dragonfly in Missouri emphasized data collected by aerial netting and examination of specimens housed in the Wilbur Enns Museum of Entomology. Dip net samples were also taken, however, to find naiads of the target species at sites where adults might not have been found and to determine whether there were associated species. Forty-one collections were made in 32 Ozark streams between mid-May and early June 1999-2000. Of the 372 taxa identified, Psephenus herricki was the most frequently associated species. Six of the 32 streams either had not been …

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. …

Historical Forest Landscape Changes In The Buffalo River Sub-Basin In Arkansas, Robert C. Weih Jr., A. Dick
Historical Forest Landscape Changes In The Buffalo River Sub-Basin In Arkansas, Robert C. Weih Jr., A. Dick
Journal of the Arkansas Academy of Science
Forested areas in the United States have been altered since the time of European settlement. For this reason, research interests have increased in comparing present day vegetation with that of the preEuroamerican era to see what changes, if any, have occurred in some of our more outstanding natural areas. Such studies have been conducted in other parts of the United States but limited research has been done in Arkansas. The General Land Office (GLO) surveys of Arkansas were originally conducted between approximately 1815 and 1850 shortly after Arkansas was acquired from France by means of the Louisiana Purchase and provides …
