Mihi Breccia: A stack of lacustrine sediments and subaqueous pyroclastic flows within the Taupo Volcanic Zone, New Zealand
Drew T. Downs
2016, Journal of Volcanology and Geothermal Research (327) 180-191
The Taupo Volcanic Zone (TVZ), New Zealand, encompasses a wide variety of arc-related strata, although most of its small-volume (non-caldera-forming) eruptions are poorly-exposed and extensively hydrothermally altered. The Mihi Breccia is a stratigraphic sequence consisting of interbedded rhyolitic pyroclastic flows and lacustrine sediments with eruption ages of 281 ± 18 to at...
Relationships of three species of bats impacted by white-nose syndrome to forest condition and management
Alexander Silvis, Roger W. Perry, W. Mark Ford
2016, General Technical Report SRS–214
Forest management activities can have substantial effects on forest structure and community composition and response of wildlife therein. Bats can be highly influenced by these structural changes, and understanding how forest management affects day-roost and foraging ecology of bats is currently a paramount conservation issue. With populations of many cave-hibernating...

Frederick S. B. Kibenge, Marcos Godoy, editor(s)
2016, Book chapter, Aquaculture virology
The first fish paramyxovirus was isolated from normal adult Chinook salmon returning to a coastal hatchery in Oregon in the fall of 1982. Subsequently, the virus was isolated from other stocks of adult Chinook salmon and one stock of adult coho salmon in California, Oregon, Washington and Alaska, leading to...
Comment on "No evidence of displacement due to wind turbines in breeding grassland songbirds"
Douglas H. Johnson
2016, The Condor (118) 674-675
A recent article published in The Condor: Ornithological Applications by Hale et al. (2014) is entitled, “No evidence of displacement due to wind turbines in breeding grassland songbirds.” The conclusion stated in that title, unfortunately, is based on inappropriate statistical analysis of data collected by the authors. In fact, their data provide evidence...
North American sturgeon otolith morphology
Marc A. Chalupnicki, Dawn E. Dittman
2016, Copeia (104) 260-266
Accurate expedient species identification of deceased sturgeon (Acipenseridae) when external physical characteristic analysis is inconclusive has become a high priority due to the endangered or threatened status of sturgeon species around the world. Examination of otoliths has provided useful information to aid in population management, age and size-class analysis, understanding...

Marc A. Chalupnicki, James H. Johnson
2016, Journal of Freshwater Ecology (31) 659-664
The foraging behavior of benthic fishes in streams is seldom examined but is vital to the health of the aquatic community. We examined the feeding ecology of the fantail darter (Etheostoma flaballere) in Trout Brook, a tributary of the Salmon River in central New York, USA. Of the six...
Stratigraphy of the north polar layered deposits of Mars from high-resolution topography
Patricio Becerra, Shane Byrne, Michael M. Sori, Sarah Sutton, Kenneth E. Herkenhoff
2016, Journal of Geophysical Research E: Planets (121) 1445-1471
The stratigraphy of the layered deposits of the polar regions of Mars is theorized to contain a record of recent climate change linked to insolation changes driven by variations in the planet's orbital and rotational parameters. In order to confidently link stratigraphic signals to insolation periodicities, a description of the...
Analysis of seafloor change at Breton Island, Gosier Shoals, and surrounding waters, 1869–2014, Breton National Wildlife Refuge, Louisiana
James G. Flocks, Joseph F. Terrano
2016, Open-File Report 2016-1069
Characterizing bathymetric change in coastal environments is an important component in understanding shoreline evolution, especially along barrier island platforms. Bathymetric change is a function of the regional sediment budget, long-term wave and current patterns, and episodic impact from high-energy events such as storms. Human modifications may also cause changes in...

Kathryn M. Potoka, Colin P. Shea, Phillip William Bettoli
2016, Transactions of the American Fisheries Society (145) 1110-1121
Sixteen darter species, including the federally endangered Boulder Darter Etheostoma wapiti, are known to occur in the Elk River, a large, flow-regulated tributary of the Tennessee River, Tennessee–Alabama. Since the construction of Tims Ford Dam (TFD) in 1970, habitat modification caused by cold, hypolimnetic water releases and peak-demand hydropower generation...

Jonathan M. Nelson, Paul J. Kinzel, Richard R. McDonald, Mark Schmeeckle
2016, Conference Paper, RiverFlow 2016
Recently developed optical and videographic methods for measuring water-surface properties in a noninvasive manner hold great promise for extracting river hydraulic and bathymetric information. This paper describes such a technique, concentrating on the method of infrared videog- raphy for measuring surface velocities and both acoustic (laboratory-based) and laser-scanning (field-based) techniques for...
Effects of spray-dried Pseudomonas fluorescens, strain CL145A (Zequanox®) on reproduction and early development of the fathead minnow (Pimephales promelas).
Diane L. Waller, James A. Luoma
2016, Report
The biopesticide, Zequanox®, is registered for dreissenid mussel control in open water systems. Previous toxicity trials with nontarget organisms, including young-of-the year of several fish species and invertebrates, demonstrated selectivity of Zequanox for dreissenids. However, data are lacking on its safety to reproductive and early life stages of fish. The...
Teleconnected ocean forcing of Western North American droughts and pluvials during the last millennium
Cody C. Routson, Connie A. Woodhouse, Jonathan T. Overpeck, Julio L. Betancourt, Nicholas P. McKay
2016, Quaternary Science Reviews (146) 238-250
Western North America (WNA) is rich in hydroclimate reconstructions, yet questions remain about the causes of decadal-to-multidecadal hydroclimate variability. Teleconnection patterns preserved in annually-resolved tree-ring reconstructed drought maps, and anomalies in a global network of proxy sea surface temperature (SST) reconstructions, were used to reassess the evidence linking ocean forcing...

Sarah N. Sells, Michael S. Mitchell, Victoria L. Edwards, Justin A. Gude, Neil J. Anderson
2016, Journal of Wildlife Management (80) 957-969
Good decision-making is essential to conserving wildlife populations. Although there may be multiple ways to address a problem, perfect solutions rarely exist. Managers are therefore tasked with identifying decisions that will best achieve desired outcomes. Structured decision making (SDM) is a method of decision analysis used to identify the most...

Matthew Smart, Jeff S. Pettis, Ned H. Jr. Euliss, Marla S. Spivak
2016, Agriculture, Ecosystems and Environment (230) 139-149
The Northern Great Plains region of the US annually hosts a large portion of commercially managed U.S. honey bee colonies each summer. Changing land use patterns over the last several decades have contributed to declines in the availability of bee forage across the region, and the future sustainability of the...
Field scale test of multi-dimensional flow and morphodynamic simulations used for restoration design analysis
Richard R. McDonald, Jonathan M. Nelson, Ryan L. Fosness, Peter O. Nelson
George Constantinescu, Marcelo H. Garcia, Dan Hanes, editor(s)
2016, Conference Paper, RiverFlow 2016
Two- and three-dimensional morphodynamic simulations are becoming common in studies of channel form and process. The performance of these simulations are often validated against measurements from laboratory studies. Collecting channel change information in natural settings for model validation is difficult because it can be expensive and under most channel forming...

Kevin M. Fraley, Jeffrey A. Falke, Richard Yanusz, Sam S. Ivey
2016, Transactions of the American Fisheries Society (145) 1077-1092
Potamodromous Rainbow Trout Oncorhynchus mykiss are an important ecological and recreational resource in freshwater ecosystems of Alaska, and increased human development, hydroelectric projects, and reduced escapement of Chinook Salmon Oncorhynchus tshawytscha may threaten their populations. We used aerial and on-the-ground telemetry tracking, a digital landscape model, and resource selection functions...
