Self-confidence of anglers in identification of freshwater sport fish
C.J. Chizinski, D. R. Martin, Kevin L. Pope
2014, Fisheries Management and Ecology (21) 448-453
Although several studies have focused on how well anglers identify species using replicas and pictures, there has been no study assessing the confidence that can be placed in angler's ability to identify recreationally important fish. Understanding factors associated with low self-confidence will be useful in tailoring education programmes to improve...

2014, Journal of Quantitative Spectroscopy and Radiative Transfer (115) 131-143
We present the scientific case to build a multiple-wavelength, active, near-infrared (NIR) instrument to measure the reflected intensity and polarization characteristics of backscattered radiation from planetary surfaces and atmospheres. We focus on the ability of such an instrument to enhance, perhaps revolutionize, our understanding of climate, volatiles and astrobiological potential...
Retirement investment theory explains patterns in songbird nest-site choice
Henry M. Streby, Jeanine M. Refsnider, Sean M. Peterson, David E. Andersen
2014, Proceedings of the Royal Society B: Biological Sciences (281)
When opposing evolutionary selection pressures act on a behavioural trait, the result is often stabilizing selection for an intermediate optimal phenotype, with deviations from the predicted optimum attributed to tracking a moving target, development of behavioural syndromes or shifts in riskiness over an individual's lifetime. We investigated nest-site choice by...

2014, Report
Wind Cave National Park (WICA) protects one of the world’s longest caves, has large amounts of high quality, native vegetation, and hosts a genetically important bison herd. The park’s relatively small size and unique purpose within its landscape requires hands-on management of these and other natural resources, all of which...
CyberShake-derived ground-motion prediction models for the Los Angeles region with application to earthquake early warning
Maren Bose, Robert Graves, David Gill, Scott Callaghan, Phillip J. Maechling
2014, Geophysical Journal International (198) 1438-1457
Real-time applications such as earthquake early warning (EEW) typically use empirical ground-motion prediction equations (GMPEs) along with event magnitude and source-to-site distances to estimate expected shaking levels. In this simplified approach, effects due to finite-fault geometry, directivity and site and basin response are often generalized, which may lead to a...
Preface

2014, Reviews in Mineralogy and Geochemistry (79) iii-v
Arsenic is perhaps history’s favorite poison, often termed the “King of Poisons” and the “Poison of Kings” and thought to be the demise of fiction’s most famous ill-fated lovers. The toxic nature of arsenic has been known for millennia with the mineral realgar (AsS), originally named “arsenikon” by Theophrastus in...
The misconception of ecosystem disservices: How a catchy term may yield the wrong messages for science and society
Ferdinando Villa, Kenneth J. Bagstad, Brian Voigt, Gary W. Johnson, Ioannis N Athanasiadis, Stefano Balbi
2014, Ecosystem Services (10) 52-53
In their recent article, Shapiro and Báldi (2014) build on the long-running narrative of “ecosystem services and disservices” (e.g., Zhang et al., 2007 ; Lyytimäki et al., 2008), describing how nature yields both benefits and harms to society. These harms include crop pests, floods, landslides, wildfires, and zoonotic disease transmission,...

Learning rate and temperament in a high predation risk environment
C. DePasquale, Tyler Wagner, G.A. Archard, B. Ferguson, V.A. Braithwaite
2014, Oecologia (176) 661-667
Living in challenging environments can influence the behavior of animals in a number of ways. For instance, populations of prey fish that experience frequent, nonlethal interactions with predators have a high proportion of individuals that express greater reaction to risk and increased activity and exploration—collectively known as temperament traits. Temperament...

Obovaria subrotunda was confirmed to be a bradytictic species, spawning in the late summer and holding glochidia in...
Resolving terrestrial ecosystem processes along a subgrid topographic gradient for an earth-system model
Z M Subin, Paul C.D. Milly, B N Sulman, Sergey Malyshev, E Shevliakova
2014, Hydrology and Earth System Sciences (11) 8443-8492
Soil moisture is a crucial control on surface water and energy fluxes, vegetation, and soil carbon cycling. Earth-system models (ESMs) generally represent an areal-average soil-moisture state in gridcells at scales of 50–200 km and as a result are not able to capture the nonlinear effects of topographically-controlled subgrid heterogeneity in...
Seismometer Self-Noise and Measuring Methods
Adam T. Ringler, R. Sleeman, Charles R. Hutt, Lind S. Gee
2014, Book chapter, Encyclopedia of Earthquake Engineering
Seismometer self-noise is usually not considered when selecting and using seismic waveform data in scientific research as it is typically assumed that the self-noise is negligibly small compared to seismic signals. However, instrumental noise is part of the noise in any seismic record, and in particular, at frequencies below a...

Jeff Tracey-PR, James K. Sheppard, Glenn K. Lockwood, Amit Chourasia, Mahidhar Tatineni, Robert N. Fisher, Robert S. Sinkovits
2014, Conference Paper, Proceedings of the 2014 Annual Conference on Extreme Science and Engineering Discovery Environment
We describe an efficient implementation of a 3D movement-based kernel density estimator for determining animal space use from discrete GPS measurements. This new method provides more accurate results, particularly for species that make large excursions in the vertical dimension. The downside of this approach is that it is much more...
Environmental variables measured at multiple spatial scales exert uneven influence on fish assemblages of floodplain lakes
Daniel J. Dembkowski, Leandro E. Miranda
2014, Hydrobiologia (721) 129-144
We examined the interaction between environmental variables measured at three different scales (i.e., landscape, lake, and in-lake) and fish assemblage descriptors across a range of over 50 floodplain lakes in the Mississippi Alluvial Valley of Mississippi and Arkansas. Our goal was to identify important local- and landscape-level determinants of fish...
