Nuclear Ribosomal Its Region Sequences For Differentiation Of Rubus Genotypes, Eric T. Stafne, John R. Clark, Allen L. Szalanski Jan 2003

Nuclear Ribosomal Its Region Sequences For Differentiation Of Rubus Genotypes, Eric T. Stafne, John R. Clark, Allen L. Szalanski

Journal of the Arkansas Academy of Science

Previous molecular investigations into Rubus species diversity have yielded significant knowledge about species relatedness. However, little work has been focused at the cultivar level. Random amplified polymorphic DNA(RAPD)-PCR studies have successfully differentiated closely related cultivars. The ability to definitively distinguish blackberry and red raspberry cultivars based on other molecular methods could prove useful in many aspects of breeding and proprietary protection. In this study, the nuclear ribosomal DNA internal transcribed spacer regions (ITS) of six Rubus cultivars were sequenced. DNA sequencing revealed little genetic variation among blackberry cultivars, but revealed distinctions between blackberry and red raspberry cultivars. Analysis by maximum-parsimony …

Beetle Diversity In An Eastern Cottonwood (Populus Deltoides Bartr.) Plantation And Adjacent Bottomland Hardwood Forest In Southeastern Arkansas, Michael D. Warriner, T. Evan Nebeker, Steven A. Tucker Jan 2002

Beetle Diversity In An Eastern Cottonwood (Populus Deltoides Bartr.) Plantation And Adjacent Bottomland Hardwood Forest In Southeastern Arkansas, Michael D. Warriner, T. Evan Nebeker, Steven A. Tucker

Journal of the Arkansas Academy of Science

Within the Lower Mississippi Alluvial Valley (LMAV),some lands cleared of bottomland hardwood forests have the potential to return to forest as a result of private sector and government interests in Populus cultivation. Specifically, monoculture plantings of eastern cottonwood (Populus deltoides Bartr.) represent an important component of many recent afforestation efforts in the region. The impact establishment of such monocultures will have on native insect communities in the LMAV is relatively unknown. To evaluate this, beetle (Coleoptera) diversity, abundance, and functional distribution were examined within an intensively managed eastern cottonwood plantation and nearby bottomland hardwood forest in southeastern Arkansas. Beetles were …

Distribution And Status Of Ophiogomphus Westfalli (Ondonata: Gomphidae) In Missouri And Arkansas, George L. Harp, Linden Trial Jan 2001

Distribution And Status Of Ophiogomphus Westfalli (Ondonata: Gomphidae) In Missouri And Arkansas, George L. Harp, Linden Trial

Journal of the Arkansas Academy of Science

Ophiogomphus westfalli is endemic to the Interior Highlands (Ozark Plateaus and Ouachita Mountains), in Missouri, Arkansas and southeastern Kansas. First described in 1985, its life history is still little known. Prior to 1997, this species was known from only six sites in Missouri and 10 in Arkansas. From late May through late July in both 1999 and 2000 we surveyed 49 sites, three of them twice each, on Missouri Ozark streams inorder to further clarify the distribution and relative abundance of this dragonfly. Adults, nymphs and/or exuviae were found at 23 sites. Literature and museum searches bring to 72 locations …

Dytiscidae (Coleoptera) Of Jackson County, Arkansas, Anthony Holt, George L. Harp

Journal of the Arkansas Academy of Science

Dytiscid beetles were surveyed to establish a baseline list for this county, which lies primarily in the Mississippi Alluvial Plain. This list was then compared with that for an Ozark county, which had been surveyed in a previous study. Eighteen sites were surveyed by Turtox Indestructible ™ dip net and funnel traps. Museum holdings and literature records were also searched. Twenty-one taxa were collected, with temporary ponds and oxbow/cypress swamps supporting the greatest diversity. These are the least disturbed sites in Jackson County. Most species collected are generally widely distributed and prefer either shaded ponds/pools with some leaf litter, or …

Recent Establishment Of The Asian Tiger Mosquito (Aedes Albopictus) In Independence County, Arkansas, David H. Jamieson, Larry A. Olson Jan 1995

Recent Establishment Of The Asian Tiger Mosquito (Aedes Albopictus) In Independence County, Arkansas, David H. Jamieson, Larry A. Olson

Journal of the Arkansas Academy of Science

Three adult Aedes albopictus were collected on 10 August 1993 within the city limits of Batesville, Arkansas. This is the firs tknown report of this species from Independence County. Subsequent investigation revealed the presence of at least three well established populations in the county, two of which were monitored on a monthly basis from Aprilto September of 1994. Peak A. albopictus numbers were recorded in July and August when the population levels were sufficient to make this mosquito a significant pest in Batesville. Our observations suggest that the Asian tiger mosquito will likely colonize other similar communities in Arkansas.

Genetic Variability In Developing Periodical Cicadas, Alvan A. Karlin, Eric C. Stout, Lance T. Adams, Lisa R. Duke, James J. English Jan 1994

Genetic Variability In Developing Periodical Cicadas, Alvan A. Karlin, Eric C. Stout, Lance T. Adams, Lisa R. Duke, James J. English

Journal of the Arkansas Academy of Science

There are few events in nature that are more predictable than the emergence of periodical cicadas. The insects emerge from the ground after 13 or 17 years (depending on brood and species) of development. Karlin et al., (1991) biochemically examined over 750 Magicicada tredecassini belonging to Brood XIX which emerged during the spring of 1985. In this study they found evidence for rapid deterioration of heterozygosity for two esterase loci,Gi-3-pdh and Gpi, and suggested that this deterioration may be related to differential mating classes. To test this hypothesis, we re-sampled from this same brood at the same location during fall …

Burying Beetle (Coleoptera: Silphidae, Nicrophorus) Surveys On Poteau Ranger District, Ouachita National Forest, Joseph C. Neal, M. Earl Stewart, Warren G. Montague

Journal of the Arkansas Academy of Science

Surveys for American burying beetles {Nicrophorus americanus Oliver) were conducted in west-central Arkansas on Poteau Ranger District of the Ouachita National Forest in1992 and 1993. A total of 2450 Nicrophorus specimens were captured in1098 trap nights. The most frequently captured specimens were N. orbicollis, N. tomentosus, and N. pustulatus. One specimen of N. americanus was also captures. Other species of beetles were also trapped and identified in this survey. Habitats sampled were primarily well-drained uplands with proposed or recent harvests of shortleaf pine (Pinus echinata). It appears that these habitats may not harbor extensive populations of N. americanus onPoteau RD.

Aquatic Macrophytes Of Two Small Northwest Arkansas Reservoirs, John J. Sullivan, Arthur V. Brown Jan 1994

Aquatic Macrophytes Of Two Small Northwest Arkansas Reservoirs, John J. Sullivan, Arthur V. Brown

Journal of the Arkansas Academy of Science

Lake Fayetteville and Lake Wedington are small reservoirs of about the same size and age that are located in northwestern Arkansas. We collected macrophytes from eleven transects around each reservoir in the autumn of 1993. Justicia (waterwillow), Typha (cat-tail), Scirpus (bulrush), Potamogeton (pondweed), and Zannichellia (horned pondweed) occur in both reservoirs. Justicia occurs most commonly in both reservoirs. The macrophytes of Lake Wedington are organized in a characteristic zonation pattern with bands from shore toward open water of emergent, floating-leaved, then submersed macrophytes. Macrophyte zonation was not as evident in Lake Fayetteville because of the low occurrence of floating leaved …

Biota Of Magazine Mountain (I): An Outline Of The Natural History Of Magazine Mountain, Robert T. Allen Jan 1991

Biota Of Magazine Mountain (I): An Outline Of The Natural History Of Magazine Mountain, Robert T. Allen

Journal of the Arkansas Academy of Science

One plant and five invertebrate species are thought to be endemic to Magazine Mountain, Logan County, Arkansas. The mountain is the highest point in the Interior Highlands reaching 2,753 feet. Previous studies have recorded over 650 species of plants including (or in addition to) 27 fern species. The animal fauna is less well known. It is suggested that an inventory of the biota of the mountain could be completed within the foreseeable future. It is further suggested that such an inventory would be useful in answering questions relevant to understanding the evolution and biogeography of selected taxa in North America. …

Survey Of 1985 Periodical Cicada (Homoptera: Magicicada) Emergence Sites In Washington County, Arkansas, With Reference To Ecological Implications, Douglas A. James, Kathy S. Williams, Kimberly G. Smith Jan 1986

Survey Of 1985 Periodical Cicada (Homoptera: Magicicada) Emergence Sites In Washington County, Arkansas, With Reference To Ecological Implications, Douglas A. James, Kathy S. Williams, Kimberly G. Smith

Journal of the Arkansas Academy of Science

Systematic roadside surveys were conducted in June 1985 in Washington County, Arkansas, to locate areas where 13-year periodical cicadas had emerged during May. Although cicadas were found in a variety of upland and bottom land forest habitats, the present cicada distribution reflects the original forest and prairie pattern in the county, even though those boundaries are now largely lost. This suggests a high degree of philopatry whereby emergency areas have remained in the same area for the last 100 years. All present day emergence areas are within the White River drainage, suggesting that it was the main cicada dispersal route …
