William J. Carswell Jr.
2016, Fact Sheet 2014-3079
Elevation data are essential to a broad range of applications, including forest resources management, wildlife and habitat management, national security, recreation, and many others. For the State of Hawaii, elevation data are critical for infrastructure and construction management, flood risk management, geologic resource assessment and hazard mitigation, natural resources conservation,...
A hierarchical community occurrence model for North Carolina stream fish
S.R. Midway, Tyler Wagner, B.H. Tracy
2016, Transactions of the American Fisheries Society (143) 1348-1357
The southeastern USA is home to one of the richest—and most imperiled and threatened—freshwater fish assemblages in North America. For many of these rare and threatened species, conservation efforts are often limited by a lack of data. Drawing on a unique and extensive data set spanning over 20 years, we modeled...
Influence of slip-surface geometry on earth-flow deformation, Montaguto earth flow, southern Italy
L. Guerriero, Jeffrey A. Coe, P. Revellio, G. Grelle, F. Pinto, F. Guadagno
2016, Geomorphology (219) 285-305
We investigated relations between slip-surface geometry and deformational structures and hydrologic features at the Montaguto earth flow in southern Italy between 1954 and 2010. We used 25 boreholes, 15 static cone-penetration tests, and 22 shallow-seismic profiles to define the geometry of basal- and lateral-slip surfaces; and 9 multitemporal maps to...
Differential response of carbon fluxes to climate in three peatland ecosystems that vary in the presence and stability of permafrost
Eugenie S. Euskirchen, C.W. Edgar, M.R. Turetsky, Mark P. Waldrop, Jennifer W. Harden
2016, Journal of Geophysical Research: Biogeosciences (119) 1576-1595
Changes in vegetation and soil properties following permafrost degradation and thermokarst development in peatlands may cause changes in net carbon storage. To better understand these dynamics, we established three sites in Alaska that vary in permafrost regime, including a black spruce peat plateau forest with stable permafrost, an internal collapse...

Andrew M. Ramey, Patrick Walther, Paul Karl Link, Rebecca L. Poulson, Benjamin R. Wilcox, George M. Newsome, Erica Spackman, J. Brown, David E. Stallknecht
2016, Transboundary and Emerging Diseases (63) 194-202
Relative to research focused on intercontinental viral exchange between Eurasia and North America, less attention has been directed towards understanding the redistribution of influenza A viruses (IAVs) by wild birds between North America and South America. In this study, we genomically characterized 45 viruses isolated from blue-winged teal (Anas discors)...

We report a population of Bigeye Shiner Notropis boops in the South Fork Hughes River drainage of the Little Kanawha River, West Virginia. A total of 27 individuals of N. boops were collected during five sampling efforts from 1999 to 2005. These specimens represent an addition to the...
High-precision relocation of long-period events beneath the summit region of Kı̄lauea Volcano, Hawai‘i, from 1986 to 2009
Robin S. Matoza, Peter M. Shearer, Paul G. Okubo
2016, Geophysical Research Letters (41) 3413-3421
Long-period (0.5–5 Hz, LP) seismicity has been recorded for decades in the summit region of Kı̄lauea Volcano, Hawai‘i, and is postulated as linked with the magma transport and shallow hydrothermal systems. To better characterize its spatiotemporal occurrence, we perform a systematic analysis of 49,030 seismic events occurring in the Kı̄lauea...

Aaron R. Cupp, Kim T. Fredricks, Christopher F. Hartleb, Mark P. Gaikowski
2016, Aquaculture Research (47) 234-242
Effects of eugenol (AQUI-S®20E, 10% active eugenol) sedation on cool water, yellow perch Perca flavescens (Mitchill), and warm water, Nile tilapia Oreochromis niloticus L. fish metabolic rates were assessed. Both species were exposed to 0, 10, 20 and 30 mg L−1 eugenol using static respirometry. In 17°C water and loading densities of 60, 120 and 240 g L−1, yellow...

Petra Wood, Kyle R. Aldinger
2016, Wilson Journal of Ornithology (126) 279-287
The Golden-winged Warbler (Vermivora chrysoptera) is one of the most rapidly declining vertebrate species in the Appalachian Mountains. It is the subject of extensive range-wide research and conservation action. However, little is known about this species' breeding ecology in high-elevation pasturelands, a breeding habitat with conservation potential considering the U.S....
Manganese nodules
James R. Hein
Jan Harff, Sven Petersen, Jorn Thiede, editor(s)
2016, Book chapter, Encyclopedia of marine geosciences
The existence of manganese (Mn) nodules (Figure 1) has been known since the late 1800s when they were collected during the Challenger expedition of 1873–1876. However, it was not until after WWII that nodules were further studied in detail for their ability to adsorb metals from seawater. Many of the...

Detecting temporal change in freshwater fisheries surveys: statistical power and the important linkages between management questions and monitoring objectives
Tyler Wagner, Brian J. Irwin, James R. Bence, Daniel B. Hayes
2016, Fisheries (38) 309-319
Monitoring to detect temporal trends in biological and habitat indices is a critical component of fisheries management. Thus, it is important that management objectives are linked to monitoring objectives. This linkage requires a definition of what constitutes a management-relevant “temporal trend.” It is also important to develop expectations for the...

Integrated water flow model and modflow-farm process: A comparison of theory, approaches, and features of two integrated hydrologic models
Emin C. Dogrul, Wolfgang Schmid, Randall T. Hanson, Tariq Kadir, Francis Chung
2016, Report
Effective modeling of conjunctive use of surface and subsurface water resources requires simulation of land use-based root zone and surface flow processes as well as groundwater flows, streamflows, and their interactions. Recently, two computer models developed for this purpose, the Integrated Water Flow Model (IWFM) from the California Department of...
Determination of dilution factors for discharge of aluminum-containing wastes by public water-supply treatment facilities into lakes and reservoirs in Massachusetts
John A. Colman, Andrew J. Massey, Sara L. Brandt
2016, Scientific Investigations Report 2011-5136
Dilution of aluminum discharged to reservoirs in filter-backwash effluents at water-treatment facilities in Massachusetts was investigated by a field study and computer simulation. Determination of dilution is needed so that permits for discharge ensure compliance with water-quality standards for aquatic life. The U.S. Environmental Protection Agency chronic standard for aluminum,...

Peter S. Coates, Mark A. Ricca, Brian G. Prochazka, Matthew L. Brooks, Kevin E. Doherty, Travis Kroger, Erik J. Blomberg, Christian A. Hagen, Michael L. Casazza
2016, PNAS (113) 12745-12750
Iconic sagebrush ecosystems of the American West are threatened by larger and more frequent wildfires that can kill sagebrush and facilitate invasion by annual grasses, creating a cycle that alters sagebrush ecosystem recovery post disturbance. Thwarting this accelerated grass–fire cycle is at the forefront of current national conservation efforts, yet...
