Erin E. Silvestri, Dale W. Griffin
2017, Report
This protocol describes the processing steps for 45 g and 9 g soil samples potentially contaminated with Bacillus anthracis spores. The protocol is designed to separate and concentrate the spores from bulk soil down to a pellet that can be used for further analysis. Soil extraction solution and mechanical shaking...
Experts correctly describe demography associated with historical decline of the endangered Indiana bat, but not recent period of stationarity

2017, PeerJ (5)
Demographic characteristics of bats are often insufficiently described for modeling populations. In data poor situations, experts are often relied upon for characterizing ecological systems. In concert with the development of a matrix model describing Indiana bat (Myotis sodalis) demography, we elicited estimates for parameterizing this model from 12 experts. We...

Andrew K. Carlson, William W. Taylor, Kelsey M. Hartikainen, Dana M. Infante, Beard Jr., Abigail Lynch
2017, Reviews in Fish Biology and Fisheries (2) 443-462
Global climate change is predicted to increase air and stream temperatures and alter thermal habitat suitability for growth and survival of coldwater fishes, including brook charr (Salvelinus fontinalis), brown trout (Salmo trutta), and rainbow trout (Oncorhynchus mykiss). In a changing climate, accurate stream temperature modeling is increasingly important for sustainable...

Nonlethal laparoscopic detection of intersex (testicular oocytes) in largemouthbass (Micropterus salmoides) and smallmouth bass (Micropterus dolomieu)
Vicki S. Blazer, Alexander H Macleod, Mark A Matsche, Lance T Yonkos
2017, Environmental Toxicology and Chemistry (36) 1924-1933
Intersex in wild fish populations has received considerable attention in the scientific literature and public media. Conventional detection of testicular oocytes (TO), the presence of immature oocytes within testis of male fish, employs transverse sectioning of excised testis and is lethal. This present study used a non-lethal laparoscopic technique to...

Resampling of spatially correlated data with preferential sampling for the estimation of frequency distributions and semivariograms
Ricardo A. Olea
2017, Stochastic Environmental Research and Risk Assessment (31) 481-491
Spatial data are commonly minimal and may have been collected in the process of confirming the profitability of a mining venture or investigating a contaminated site. In such situations, it is common to have measurements preferentially taken in the most critical areas (sweet spots, allegedly contaminated areas), thus conditionally biasing...

Lisa M. O’Connor, Thomas C. Pratt, Todd B. Steeves, Brian Stephens, Michael A. Boogaard, Cheryl Kaye
2017, Journal of Great Lakes Research (43) 189-198
The lampricides 3-trifluoromethyl-4-nitrophenol (TFM) and 2′, 5-dichloro-4′-nitrosalicylanilide (niclosamide) are used to control sea lamprey (Petromyzon marinus), an invasive species in the Great Lakes. Age-0 lake sturgeon (Acipenser fulvescens), a species of conservationconcern, share similar stream habitats with larval sea lampreys and these streams can be...

Herve Piegay, Bertrand Moulin, Cliff R. Hupp
2017, Geomorphology (279) 27-43
When and whence does wood enter large mountain alluvial rivers? How stable through time are characteristics and quantities of wood deposited in a reach? These simple questions related to the complex practice of wood budgeting are explored on the Isère...
Simulation of earthquake ground motions in the eastern United States using deterministic physics‐based and site‐based stochastic approaches
Sanaz Rezaeian, Stephen H. Hartzell, Xiaodan Sun, Carlos Mendoza
2017, Bulletin of the Seismological Society of America (107) 149-168
Earthquake ground‐motion recordings are scarce in the central and eastern United States (CEUS) for large‐magnitude events and at close distances. We use two different simulation approaches, a deterministic physics‐based method and a site‐based stochastic method, to simulate ground motions over a wide range of magnitudes. Drawing...

2017, Scientific Data (4) 1-19
Seasonal agricultural drought monitoring systems, which rely on satellite remote sensing and land surface models (LSMs), are important for disaster risk reduction and famine early warning. These systems require the best available weather inputs, as well as a long-term historical record to contextualize current observations. This article introduces the Famine...
Pectoral fin contact as a mechanism for social bonding among dolphins
Kathleen Dudzinski, Christine Ribic
2017, Animal Behavior and Cognition (4) 30-48
Bottlenose dolphins are large-brained social mammals residing in a fission-fusion society with relationships that are established and maintained over decades. We examined a decade-long data set of inter-individual pectoral fin contact exchanges to better understand how dolphins share information via tactile contact. Sex and age are significant factors in pectoral...
Compartmentalization of the Coso East Flank geothermal field imaged by 3-D full-tensor MT inversion
Nathaniel J. Lindsey, J. Ole Kaven, Nicholas C. Davatzes, Gregory A. Newman
2017, Geophysical Journal International (208) 652-662
Previous magnetotelluric (MT) studies of the high-temperature Coso geothermal system in California identified a subvertical feature of low resistivity (2–5 Ohm m) and appreciable lateral extent (>1 km) in the producing zone of the East Flank field. However, these models could not reproduce gross 3-D effects in the recorded data. We perform...

Austin A. Rizzo, Donald J. Brown, Stuart A. Welsh, Patricia A. Thompson
2017, The American Midland Naturalist (178) 123-131
Population monitoring is an essential component of endangered species recovery programs. The federally endangered Diamond Darter Crystallaria cincotta is in need of an effective monitoring design to improve our understanding of its distribution and track population trends. Because of their small size, cryptic coloration, and nocturnal behavior, along with limitations associated with...
Dynamic strains for earthquake source characterization
Andrew J. Barbour, Brendan W. Crowell
2017, Seismological Research Letters (88) 354-370
Strainmeters measure elastodynamic deformation associated with earthquakes over a broad frequency band, with detection characteristics that complement traditional instrumentation, but they are commonly used to study slow transient deformation along active faults and at subduction zones, for example. Here, we analyze dynamic strains at Plate Boundary Observatory (PBO) borehole strainmeters...

2017, GIScience and Remote Sensing (54) 230-257
Drought is a natural climatic phenomenon that occurs throughout the world and impacts many sectors of society. To help decision-makers reduce the impacts of drought, it is important to improve monitoring tools that provide relevant and timely information in support of drought mitigation decisions. Given that drought is a complex...
