    RELATIONSHIPS BETWEEN DEAD WOOD AND ARTHROPODS IN THE SOUTHEASTERN UNITED STATES by MICHAEL DARRAGH ULYSHEN (Under the Direction of James L. Hanula) ABSTRACT The importance of dead wood to maintaining forest diversity is now widely recognized. However, the habitat associations and sensitivities of many species associated with dead wood remain unknown, making it difficult to develop conservation plans for managed forests. The purpose of this research, conducted on the upper coastal plain of South Carolina, was to better understand the relationships between dead wood and arthropods in the southeastern United States. In a comparison of forest types, more beetle species emerged from logs collected in upland pine-dominated stands than in bottomland hardwood forests. This difference was most pronounced for Quercus nigra L., a species of tree uncommon in upland forests. In a comparison of wood postures, more beetle species emerged from logs than from snags, but a number of species appear to be dependent on snags including several canopy specialists. In a study of saproxylic beetle succession, species richness peaked within the first year of death and declined steadily thereafter. However, a number of species appear to be dependent on highly decayed logs, underscoring the importance of protecting wood at all stages of decay. In a study comparing litter-dwelling arthropod abundance at different distances from dead wood, arthropods were more abundant near dead wood than away from it. In another study, ground- dwelling arthropods and saproxylic beetles were little affected by large-scale manipulations of dead wood in upland pine-dominated forests, possibly due to the suitability of the forests surrounding the plots.

  • Scientific Note
    The Coleopterists Bulletin, 61(2):224-226. 2007. SCIENTIFIC NOTE Phloeoxena signata (Dejean): Northern range extensions to Maryland and Tennessee, U.S.A., and the first record for Costa Rica (Coleoptera: Carabidae) The recent discovery of a specimen of Phloeoxena signata (Carabidae: Lebiini: Pericalina) at the Patuxent Research Refuge in Prince Georges County, Maryland prompted a review of the known distribution of this primarily tropical ground beetle. It is the most widespread and variable species of the genus, which includes 32 species and has its center of diversity in Middle America (Shpeley and Ball 2000). Phloeoxena signata has been reported from Panama to North Carolina (Ball 1975; Shpeley and Ball 2000) and southern Virginia (Hoffman 1997) making the Maryland record the first for the state and a noteworthy northward range extension (from Halifax County, Virginia, a distance of about 380 km.). Additional Virginia specimens have now been collected, and several recent Tennessee specimens are reported, also representing a new state record. We also report the first known record for the species in Costa Rica, filling a gap in the known distribution between Nicaragua and central Panama. The specimens are deposited in the USNM, Smithsonian Institution,Washington, the Carnegie Museum of Natural History, Pittsburgh, and U.S. National Park Service voucher collection at the George Washington Memorial Parkway Headquarters, Virginia. The Maryland specimen (Fig. 1), a female, is labeled: "MARYLAND: Pr. Geo. Co., 10 km NE Bowie (Central Tract Patuxent Res. Ref), 39°03'N, 76°49'W, 24 March 2006, Coll. W. E. Steiner / Under bark of dead standing red maple in open swamp forest." The beetle was found under loose, dry bark about 1.5 m above ground on the north (shaded) side of a trunk about 25 cm in diameter.

  • Section D – Federal Oil and Gas Leasing Availability
    CHAPTER 3 – AFFECTED ENVIRONMENT GEORGE WASHINGTON NATIONAL FOREST AND ENVIRONMENTAL CONSEQUENCES SECTION D – FEDERAL OIL AND GAS LEASING AVAILABILITY INTRODUCTION This section of the Final EIS identifies George Washington National Forest lands that could be made available for oil and gas leasing, in accordance with the Mineral Leasing Act, under various leasing alternatives. It also describes the affected environment and discusses reasonably foreseeable impacts of oil and gas activities on the environment resulting from each leasing alternative. Oil and gas leasing is identified as a significant issue in Chapter 1 of the Final EIS. Issues and concerns expressed by the public and government agencies during the public comment period for this EIS have been addressed by the analysis. Additional discussion of specific concerns with gas development is in FEIS, Appendix I- Analysis of Concerns and Risks of Horizontal Drilling and Hydraulic Fracturing. Management of the federal leasable oil and gas resources is a shared responsibility between the Forest Service and the U.S. Department of Interior. The Bureau of Land Management (BLM) has a major role in issuing and supervising operations on licenses, permits, and leases for federal leasable minerals. BLM cannot issue oil and gas leases for lands administered by the Forest Service without consent from the Secretary of Agriculture. As the agency responsible for federal oil and gas lease issuance and administration, the BLM participated in this EIS as a cooperating agency. This analysis will be used by both agencies as the basis for making oil and gas leasing decisions under their authorities. The responsible officials of the Forest Service and BLM may release separate Records of Decision.

  • Characteristics of Mixed-Oak Forest Ecosystems in Southern Ohio Prior to the Reintroduction of Fire
    United States Department of Characteristics of Mixed-Oak Agriculture Forest Service Forest Ecosystems in Northeastern Research Station Southern Ohio Prior to the General Technical Reintroduction of Fire Report NE-299 Abstract Mixed-oak forests occupied much of the Unglaciated Allegheny Plateau region of southern Ohio at the onset of Euro-American settlement (ca. 1800). Historically, Native Americans used fire to manage the landscape and fire was frequent throughout the 19th and early 20th centuries during extensive forest harvesting and then re-growth. Today, though mixed-oak forests remain dominant across much of the region, oak regeneration is often poor as other tree species (e.g., maples) are becoming much more abundant. This shift has occurred concurrently with fire suppression policies that began in 1923. A multidisciplinary experiment was initiated in southern Ohio to explore the use of prescribed fire as a tool to improve the sustainability of mixed-oak forests. This report describes the experimental design and study areas, and provides baseline data on ecosystem characteristics prior to prescribed fire treatments. Chapters describe forest history, an integrated moisture index, geology and soils, understory light environments, understory vegetation, tree regeneration, overstory vegetation, foliar nutrient status, arthropods, and breeding birds.

Steury U.S. National Park Service 700 George Washington Memorial Parkway Turkey Run Park Headquarters McLean, Virginia 22101 Peter W. Messer 4315 W. Riverlake Drive Mequon, Wisconsin 53092 ABSTRACT One-hundred eighty-four species in 70 genera of geadephagan beetles (183 carabids and one rhysodid) were documented during a nine-year field survey of a national park site (George Washington Memorial Parkway) that spans parts of Fairfax and Arlington counties and the City of Alexandria in Virginia, and the District of Columbia. The capture of Elaphropus quadrisignatus (Duftschmid) represents the second record for the New World. Seven species, E. quadrisignatus, Harpalus rubripes (Duftschmid), Microlestes pusio (LeConte), Platynus opaculus LeConte, Pterostichus permundus (Say), P. sculptus LeConte, and Scarites vicinus Chaudoir are documented for the first time from the Commonwealth. Seven species, Anisodactylus dulcicollis (LaFerté-Sénectère), Elaphropus anceps (LeConte), E. saturatus (Casey), Oodes americanus Dejean, P. permundus, S. vicinus, and Tachys potomaca (Erwin) are documented for the first time from the District of Columbia. The study increases the number of geadephagan beetles known from the Potomac River Gorge to 255 species and the number from Virginia to 543 taxa. Hand picking and Malaise traps proved to be the most successful capture methods of the eight methods employed during the survey. Periods of adult activity, based on dates of capture, are given for each species.

Sims Department of Entomology Smithsonian Institution Washington, D.C. 20560 U. S. A. Quaestiones Entomologicae 20:351-466 1984 ABSTRACT The fauna of the Greater Antilles was extensively sampled and studied by P.J. Darlington, Jr., beginning with his early field trips there in 1934 and ending with his paper on tropical island carabids in 1970. The Lesser Antilles and Bahamas have had far less attention; most islands have not yet been sampled. The following tribes are recorded within the geographic area covered by the present study, which includes the Greater and Lesser Antilles, Bahamas, and most smaller islands not on the continental shelf: Carabini; Megacephalini; "Cicindelini; Enceladini; Pseudomorphini; Scaritini; "Clivinini; Ozaenini; Brachinini; 'Rhysodini; Trechini; Pogonini; "Bembidiini; Morionini; *Pterostichini; Panagaeini; Callistini; Oodini; Licinini; 'Harpalini; Ctenodactylini; Perigonini; Lachnophorini; Cyclosomini; Masoreini; Pentagonicini; Odacanthini; 'Lebiini; *Zuphiini; Galeritini. The tribes whose names are marked with an asterisk each have more than a dozen species thus far recorded from the West Indies. The tribes which occur in this area are also extensively distributed in the world, and are well represented in the Neotropical Region.
