Studying wind energy/bird interactions: a guidance document. Metrics and methods for determining or monitoring potential impacts on birds at existing and proposed wind energy sites Studying wind energy/bird interactions: a guidance document. Metrics and methods for determining or monitoring potential impacts on birds at existing and proposed wind energy sites
In the 1980s little was known about the potential environmental effects associated with large scale wind energy development. Although wind turbines have been used in farming and remote location applications throughout this country for centuries, impacts on birds resulting from these dispersed turbines had not been reported. Thus early wind energy developments were planned, permitted...

Assessing trail conditions in protected areas: Application of a problem-assessment method in Great Smoky Mountains National Park, USA Assessing trail conditions in protected areas: Application of a problem-assessment method in Great Smoky Mountains National Park, USA
The degradation of trail resources associated with expanding recreation and tourism visitation is a growing management problem in protected areas worldwide. In order to make judicious trail and visitor management decisions, protected area managers need objective and timely information on trail resource conditions. This paper introduces a trail survey method that efficiently characterizes...

Intraspecific phylogeography of Lasmigona subviridis (Bivalvia: Unionidae): Conservation implications of range discontinuity Intraspecific phylogeography of Lasmigona subviridis (Bivalvia: Unionidae): Conservation implications of range discontinuity
A nucleotide sequence analysis of the first internal transcribed spacer region (ITS-1) between the 5.8S and 18S ribosomal DNA genes (640 bp) and cytochrome c oxidase subunit I (COI) of mitochondrial DNA (mtDNA) (576 bp) was conducted for the freshwater bivalve Lasmigona subviridis and three congeners to determine the utility of these regions in identifying phylogeographic and...

Non-lethal sampling for the detection of Myxobolus cerebralis in asymptomatic rainbow trout Non-lethal sampling for the detection of Myxobolus cerebralis in asymptomatic rainbow trout
We have described in previous reports (Schill et al., 1998) the development of a polymerase chain reaction (PCR) amplification of 18S ribosomal RNA for the detection of Myxozoan parasites. Oligonucleotide primers were developed by multiple alignment of Myxozoan sequence information and analysis by a custom-written computer program (PRIM). Candidate pairs of primer sequences were then...

Three-dimensional velocity structure of Siletzia and other accreted terranes in the Cascadia forearc of Washington Three-dimensional velocity structure of Siletzia and other accreted terranes in the Cascadia forearc of Washington
Eocene mafic crust with high seismic velocities underlies much of the Oregon and Washington forearc and acts as a backstop for accretion of marine sedimentary rocks from the obliquely subducting Juan de Fuca slab. Arc-parallel migration of relatively strong blocks of this terrane, known as Siletzia, focuses upper crustal deformation along block boundaries, which are potential sources of

Occurrence of organochlorine compounds in whole fish tissue from streams of the lower Susquehanna River Basin, Pennsylvania and Maryland, 1992 Occurrence of organochlorine compounds in whole fish tissue from streams of the lower Susquehanna River Basin, Pennsylvania and Maryland, 1992
Tissue samples of whole body white sucker (Catostomus commersoni) were collected at 15 sites and smallmouth bass (Micropterus dolomieu) were collected at 5 sites during 1992 in the Lower Susquehanna River Basin to determine the occurrence and distribution of 28 selected organochlorine compounds as part of the U.S. Geological Survey’s National Water-Quality Assessment (NAWQA) Program...

Distribution of Trichloroethylene and Geologic Controls on Contaminant Pathways near the Royal River, McKin Superfund Site Area, Gray, Maine Distribution of Trichloroethylene and Geologic Controls on Contaminant Pathways near the Royal River, McKin Superfund Site Area, Gray, Maine
Vapor-diffusion samplers were used in the autumn of 1997 to determine the lateral extent and distribution of concentrations of a trichloroethylene (TCE) plume in the ground-water discharge area near the McKin Superfund Site, Gray, Maine. Analyses of vapor in the samplers identified a plume about 800 feet wide entering the river near Boiling Springs, an area of ground-water discharge on...

Basic Requirements for Collecting, Documenting, and Reporting Precipitation and Stormwater-Flow Measurements Basic Requirements for Collecting, Documenting, and Reporting Precipitation and Stormwater-Flow Measurements
Accurate and representative precipitation and stormwater-flow data are crucial for use of highway- or urban-runoff study results, either individually or in a regional or national synthesis of stormwater-runoff data. Equally important is information on the level of accuracy and representativeness of this precipitation and stormwaterflow data. Accurate and representative measurements of
