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 …


Status Of Birds Newly Recorded In Arkansas Since 1985, Douglas A. James, Joseph C. Neal, Max Parker, Charles Mills Jan 2007

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.


Survey Of Nesting By Cliff Swallows (Petrochelidon Pyrrhonota) And Barn Swallows (Hirundo Rustica) At Highway Bridges In Southern Arkansas, C. Renn Tumlison Jan 2007

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 …


Habitat Factors Affecting Trap Success Of Swamp Rabbits In Southeastern Arkansas During A Flooding Event, Blair Smyth, Karen B. Vale, Robert E. Kissell Jr. Jan 2007

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 Jan 2007

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 …

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 Jan 2007

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 …


Effects Of Light Regime And Season Of Clipping On The Growthof Cherrybark Oak, White Oak, Persimmon, And Sweetgum Sprouts, Robert L. Ficklin, Michael G. Shelton Jan 2007

Effects Of Light Regime And Season Of Clipping On The Growthof Cherrybark Oak, White Oak, Persimmon, And Sweetgum Sprouts, Robert L. Ficklin, Michael G. Shelton

Journal of the Arkansas Academy of Science

A mixture of cherrybark oak (Quercus pagoda Raf.), white oak (Q. alba L.), persimmon (Diospyros virginiana L.), and sweetgum (Liquidambar styraciflua L.) seedlings was grown in shadehouses to simulate light conditions beneath a canopy. After the first growing season, two release treatments were implemented (released and not released), and treatments were conducted during two seasons (winter and spring). All seedlings were clipped at 2.5 em from the groundline in height when treatments were imposed. Survival of persimmon and sweetgum was 100% following clipping. There appeared to be a weak seasonal effect on oak survival, especially for white oak; survival was …


Planting Techniques For Establishing Loblolly Pine Seedlings On Two Subsoiled Sites In Arkansas, Jamie L. Schuler Jan 2007

Planting Techniques For Establishing Loblolly Pine Seedlings On Two Subsoiled Sites In Arkansas, Jamie L. Schuler

Journal of the Arkansas Academy of Science

The presence of soil compaction and root-restricting layers (e.g., plow pans) resulting from long-term agricultural practices often poses difficulties when converting these sites into loblolly pine plantations. Subsoiling is usually prescribed to alleviate any problems with soil strength. Subsoiling also creates soil conditions that may aid or hinder planting seedlings. The interaction of planting location. either in the furrow or the adjacent 0.3. 0.9 or 1.5 ft, and planting depth on 2 marginal crop lands was assessed in this study. Planting seedlings in the furrow and deep planting (to the terminal bud) resulted in better growth and increased survival after …


Recent Observations Of The Distribution Of Woodchucks (Marmota Monax) In Arkansas, C. Renn Tumlison, D. Blake Sasse, Todd Pennington, Nicole Freeman Jan 2007

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 …


Ants (Hymenoptera: Formicidae) Of Arkansas Post National Memorial, David M. General, Lynne C. Thompson Jan 2007

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.

Characterization Of Bacteriophages Of Pseudomonas Syringae Pv. Tomato, Sara E. Prior, Amanda J. Andrews, Russell O. Nordeen Jan 2007

Characterization Of Bacteriophages Of Pseudomonas Syringae Pv. Tomato, Sara E. Prior, Amanda J. Andrews, Russell O. Nordeen

Journal of the Arkansas Academy of Science

Bacteriophages from supernatants of the plant pathogenic bacteria Pseudomonas syringae pv. tomato (P. tomato) were isolated, enriched, and purified by density block centrifugation in cesium chloride (CsCl) step gradients. The DNA from purified phage was isolated and digested with the restriction endonucleases EcoRl or HindIII. Three different DNA fingerprint patterns were determined indicating 3 unique phage isolates. Genome sizes of the phage ranged from 40 to 52 kilobases (kB). Buoyant densities of phage particles in CsCI varied from 1.36 to 1.51 glml. Electron microscopy revealed a single morphological type with an elongated polyhedral head and a long tail indicating the …
