Backyard "Bug" Collecting Results In 6 New State Records For Arkansas, U.S.A., Stephen W. Chordas Iii, J. Kremers
Backyard "Bug" Collecting Results In 6 New State Records For Arkansas, U.S.A., Stephen W. Chordas Iii, J. Kremers
Journal of the Arkansas Academy of Science
The aquatic Hemiptera of Arkansas are fairly well documented (see Chordas et al. 2005), but the terrestrial bugs are less well known. Recent projects and publications have begun to address this deficiency. Including the 6 reported herein, there have been 64 Hemiptera species newly recorded for Arkansas between 2005 and 2009 (Chordas et al. 2005, Chordas and Kovarik 2008a, Chordas and Kovarik 2008b). The second author is an invertebrate enthusiast who maintains a large personal collection. The content of this collection is primarily an accumulation of invertebrates captured on or around his property in Clarksville (Johnson County) Arkansas (Figure 1). …

Recent Collections And Additional Records Of Collembola From Arkansas Caves, Michael E. Slay, G. O. Graening
Recent Collections And Additional Records Of Collembola From Arkansas Caves, Michael E. Slay, G. O. Graening
Journal of the Arkansas Academy of Science
Recent collections and additional records of Collembola from caves in Arkansas are reported. Based on these collections and review of the literature, 35 collembolan species are known from Arkansas caves. Included in this group are 10 troglobiotic, or cave-limited, species: Lethemurus missus, Pygmarrhopalites buffaloensis, Pygmarrhopalites clarus, Pygmarrhopalites dubius, Pygmarrhopalites youngsteadtii, Pseudosinella dubia, Pseudosinella testa, Sinella barri, Sinella cavernarum, and Typhlogastrura fousheensis. Three of these species, Py. buffaloensis, Py. youngsteadtii, T. fousheensis, are endemic to Arkansas, while Ps. dubia is known only from the Ozark Plateaus Ecoregion. The remaining species are more widespread. Lethemurus missus, Ps. georgia, Ps. testa, and S. …

Aquatic Macroinvertebrates Collected From Thirty-Two Missouri Ozark Streams, George L. Harp, Phoebe A. Harp, Samuel B. Mccord
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 …

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 …

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
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. …

The Effects Of Nematode Infection And Mi-Mediated Resistance In Tomato (Solanum Lycopersicum) On Plant Fitness, Brandon P. Corbett
The Effects Of Nematode Infection And Mi-Mediated Resistance In Tomato (Solanum Lycopersicum) On Plant Fitness, Brandon P. Corbett
Inquiry: The University of Arkansas Undergraduate Research Journal
The Mi gene in tomato (Solanum lycopersicum) is a single, dominant resistance (R) gene that confers resistance against several species of insects and root-knot nematodes. Tis study examined the impact of root-knot nematode infestation and the plant growth and reproduction of near-isogenic tomato cultivars with and without Mi. The objectives of this experiment were to examine the potential fitness costs and benefits of the R gene-mediated herbivore resistance, and to explore the role of nematodes as a selection pressure favoring plants that carry Mi. Mi-mediated resistance dramatically reduced nematode reproduction on tomato. In the presence of nematodes, plants that carried …

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 …

Ants (Hymenoptera: Formicidae) Of Arkansas Post National Memorial, David M. General, Lynne C. Thompson
Journal of the Arkansas Academy of Science
A combination of techniques was used to collect ants at the Arkansas Post National Memorial, Arkansas County. The techniques were wood breaking, leaf-litter sifting with Berlese extraction, tree baiting, pitfall trapping, and visual searching. Twenty-five genera and 46 species were collected. Three genera are new distributional records for the state: namely, Discothyrea, Proceratium, Protomognathus, and Strumigenys.. Nine species are new state records. Fourteen of the genera and 32 of the species collected are new records for Arkansas County.
