Awell-preserved conodont fauna from the Pennsylvanian Excello Shale of Iowa, U. S. A.
A superbly preserved discrete element conodont fauna has been recovered from carbonate concretions from the upper Desmoinesian (Pennsylvanian) Excello Shale at two localities in south-central Iowa. The multielement apparatuses for Gondolella wardlawi (new species), Idiognathodus acutus, Idioprioniodus conjunctus, and Neognathodus roundyi are...
Merlynd K. Nestell; Wardlaw, Bruce R.; John P. Pope Comparative mitogenomic analyses of three North American stygobiont amphipods of the genus Stygobromus (Crustacea: Amphipoda)
The mitochondrial genomes of three North American stygobiont amphipods Stygobromus tenuis potomacus, S. foliatus and S. indentatus collected from Caroline County, VA, were sequenced using a shotgun sequencing approach on an Illumina NextSeq500 (Illumina Inc., San Diego, CA). All three mitogenomes displayed 13 protein-...

Bailey, Christopher M.; Sherwood, W. Cullen; Eaton, L. Scott; Powars, David S.; Smoot, Joseph P. Estimating abundance
This chapter provides a non-technical overview of ‘closed population capture–recapture’ models, a class of well-established models that are widely applied in ecology, such as removal sampling, covariate models, and distance sampling. These methods are regularly adopted for studies of reptiles, in order to estimate abundance from counts of marked...
Sutherland, Chris; Royle, Andy Estimating abundance: Chapter 27
This chapter provides a non-technical overview of ‘closed population capture–recapture’ models, a class of well-established models that are widely applied in ecology, such as removal sampling, covariate models, and distance sampling. These methods are regularly adopted for studies of reptiles, in order to estimate abundance from counts of marked...
Royle, J. Andrew Forest structure of oak plantations after silvicultural treatment to enhance habitat for wildlife
During the past 30 years, thousands of hectares of oak-dominated bottomland hardwood plantations have been planted on agricultural fields in the Mississippi Alluvial Valley. Many of these plantations now have closed canopies and sparse understories. Silvicultural treatments could create a more heterogeneous forest structure, with canopy gaps and...
Schweitzer, Callie Jo; Clatterbuck, Wayne K.; Oswalt, Christopher M.; Twedt, Daniel J.; Phillip, Cherrie-Lee P.; Guilfoyle, Michael P.; Wilson, R. Randy Geologic context of large karst springs and caves in the Ozark National Scenic Riverways, Missouri
The ONSR is a karst park, containing many springs and caves. The “jewels” of the park are large springs, several of first magnitude, that contribute significantly to the flow and water quality of the Current River and its tributaries. Completion of 1:24,000-scale geologic mapping of the park and surrounding river basin, along with synthesis of...
Weary, David J.; Orndorff, Randall C. Geology and geomorphology of the Carolina Sandhills, Chesterfield County, South Carolina
This two-day field trip focuses on the geology and geomorphology of the Carolina Sandhills in Chesterfield County, South Carolina. This area is located in the updip portion of the U.S. Atlantic Coastal Plain province, supports an ecosystem of longleaf pine (Pinus palustris) and wiregrass (Aristida stricta), and contains three major geologic map...
Swezey, Christopher S.; Fitzwater, Bradley A.; Whittecar, G. Richard Geology of the Mount Rogers area, revisited: Evidence of Neoproterozoic continental rifting, glaciation, and the opening and closing of the Iapetus ocean, Blue Ridge, VA–NC–TN
Recent field and geochronological studies in eight 7.5-minute quadrangles near Mount Rogers in Virginia, North Carolina and Tennessee recognize important stratigraphic and structural relationships for the Neoproterozoic Mount Rogers and Konnarock formations, the northeast end of the Mountain City window, the separation of Mesoproterozoic rocks of...
Merschat, Arthur J.; Merschat, Arthur J.; Southworth, C. Scott; Holm-Denoma, Christopher S.; McAleer, Ryan J. Hematology results from experimental exposure of sandhill cranes to West Nile virus
West Nile virus is a deadly virus for young cranes. In testing two different vaccines on both adult sandhill cranes (Grus canadensis), we discovered that some blood parameters are altered by exposure to the virus. White blood cell counts were the most obvious, and may be used as an indicator of West Nile virus exposure in cranes. Other hematology...
Olsen, Glenn H. In-air hearing of a diving duck: A comparison of psychoacoustic and auditory brainstem response thresholds
Auditory sensitivity was measured in a species of diving duck that is not often kept in captivity, the lesser scaup. Behavioral (psychoacoustics) and electrophysiological [the auditory brainstem response (ABR)] methods were used to measure in-air auditory sensitivity, and the resulting audiograms were compared. Both approaches yielded audiograms...
Crowell, Sara E.; Wells-Berlin, Alicia M.; Therrien, Ronald E.; Yannuzzi, Sally E.; Carr, Catherine E. Loamy, two-storied soils on the outwash plains of southwestern lower Michigan: Pedoturbation of loess with the underlying sand
Soils on many of the outwash plains in southwestern Michigan have loamy upper profiles, despite being underlain by sand-textured outwash. The origin of this upper, loamy material has long been unknown. The purpose of this study is to analyze the spatio-textural characteristics of these loamy-textured sediments to ascertain their origin(s). The...
