A. I. Gevaert, A. J. Teuling, R. Uijlenhoet, Stephen B. DeLong, T. E. Huxman, L. A. Pangle, David D. Breshears, J. Chorover, John D. Pelletier, S. R. Saleska, X. Zeng, Peter A. Troch
2014, Hydrology and Earth System Sciences (18) 3681-1692
Subsurface flow and storage dynamics at hillslope scale are difficult to ascertain, often in part due to a lack of sufficient high-resolution measurements and an incomplete understanding of boundary conditions, soil properties, and other environmental aspects. A continuous and extreme rainfall experiment on an artificial hillslope at Biosphere 2's Landscape...
Self-recognition in corals facilitates deep-sea habitat engineering
Sebastian J Hennige, Cheryl L. Morrison, Armin U. Form, Janina Buscher, Nicholas A. Kamenos, J. Murray Roberts
2014, Scientific Reports (4) 1-7
The ability of coral reefs to engineer complex three-dimensional habitats is central to their success and the rich biodiversity they support. In tropical reefs, encrusting coralline algae bind together substrates and dead coral framework to make continuous reef structures, but beyond the photic zone, the cold-water coral Lophelia pertusa also...
Evidence of natural reproduction by Muskellunge in middle Tennessee rivers
Lila H. Warren, Phillip William Bettoli
2014, Southeastern Naturalist (13) 506-514
Native Esox masquinongy (Muskellunge) in the Cumberland River drainage, TN, were nearly extirpated in the 1970s due to decades of over-fishing and habitat degradation from coal mining, logging, and other land-use practices. In an effort to preserve the species in that drainage, a stocking program began in 1976 in the upper Caney...
A comparison of resident fish assemblages in managed and unmanaged coastal wetlands in North Carolina and South Carolina
Kelly F. Robinson, Cecil A. Jennings
2014, Southeastern Naturalist (13) 237-260
The dominant fish species within impounded coastal wetlands in the southeastern US may be different from the species that dominate natural marshes. We tested the hypothesis that resident fish assemblages inhabiting impounded coastal wetlands in South Carolina would differ from resident assemblages in natural marshes of the southeastern United States....

Caleb G. Huber, Timothy B. Grabowski, Reynaldo Patino, Kevin L. Pope
2014, Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science (6) 170-180
Common Snook Centropomus undecimalis were once abundant off the Texas coast, but these populations are now characterized by low abundance and erratic recruitment. Most research concerning Common Snook in North America has been conducted in Florida and very little is known about the specific biology and habitat needs of Common Snook in...
Post-breeding migration of Dutch-breeding black-tailed godwits: timing, routes, use of stopovers, and nonbreeding destinations
Jos C. E. W. Hooijmeijer, Nathan R. Senner, T. Lee Tibbitts, Robert E. Gill Jr., David C. Douglas, Leo W. Bruinzeel, Eddy Wymenga, Theunis Piersma
2014, Ardea (101) 141-152
Conservation of long-distance migratory shorebirds is complex because these species use habitats spread across continents and hemispheres, making identification of critical habitats and potential bottlenecks in the annual cycle especially difficult. The population of Black-tailed Godwits that breeds in Western Europe, Limosa limosa limosa, has declined precipitously over the past...
Spawning behavior in Atlantic cod: analysis by use of data storage tags
Timothy B. Grabowski, Vilhjalmur Thorsteinsson, Gudrun Marteinsdottir
2014, Marine Ecology Progress Series (506) 279-290
 Electronic data storage tags (DSTs) were implanted into Atlantic cod captured in Icelandic waters from 2002 to 2007 and the depth profiles recovered from these tags (females: n = 31, males: n = 27) were used to identify patterns consistent with published descriptions of cod courtship and spawning behavior. The individual...
Assessing distribution of migratory fishes and connectivity following complete and partial dam removals in a North Carolina River
Joshua K. Raabe, Joseph E. Hightower
2014, North American Journal of Fisheries Management (34) 955-969
Fish, especially migratory species, are assumed to benefit from dam removals that restore connectivity and access to upstream habitat, but few studies have evaluated this assumption. Therefore, we assessed the movement of migratory fishes in the springs of 2008 through 2010 and surveyed available habitat in the Little River, North...
Understanding the value of imperfect science from national estimates of bird mortality from window collisions
Craig S. Machtans, Wayne E. Thogmartin
2014, Condor (116) 3-7
The publication of a U.S. estimate of bird–window collisions by Loss et al. is an example of the somewhat contentious approach of using extrapolations to obtain large-scale estimates from small-scale studies. We review the approach by Loss et al. and other authors who have published papers on human-induced avian mortality...

Santa Rosa Island (SRI) is the second-largest of the California Channel Islands. It is one of 4 east–west aligned islands forming the northern Channel Islands chain, and one of the 5 islands in Channel Islands National Park. The landforms, and collections of landforms called landscapes, of Santa Rosa Island have...
Quantifying spatial scaling patterns and their local and regional correlates in headwater streams: Implications for resilience
Emma Gothe, Leonard Sandin, Craig R. Allen, David G. Angeler
2014, Ecology and Society (19)
The distribution of functional traits within and across spatiotemporal scales has been used to quantify and infer the relative resilience across ecosystems. We use explicit spatial modeling to evaluate within- and cross-scale redundancy in headwater streams, an ecosystem type with a hierarchical and dendritic network structure. We assessed the cross-scale...
Productivity of functional guilds of fishes in managed wetlands in coastal South Carolina
Kelly F. Robinson, Cecil A. Jennings
2014, Journal of Fish and Wildlife Management (5) 70-86
In coastal South Carolina, many wetlands are impounded and managed as migratory waterfowl habitat. Impoundment effects on fish production and habitat quality largely are unknown. We used the size-frequency method to estimate summer production of fish guilds in three impoundments along the Combahee River, South Carolina. We predicted that guild-specific...
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...

Fertilizer consumption and energy input for 16 crops in the United States
Sheila E. Amenumey, Paul D. Capel
2014, Natural Resources Research (23) 299-309
Fertilizer use by U.S. agriculture has increased over the past few decades. The production and transportation of fertilizers (nitrogen, N; phosphorus, P; potassium, K) are energy intensive. In general, about a third of the total energy input to crop production goes to the production of fertilizers, one-third to mechanization, and...
The environmental geochemistry of Arsenic – An overview
Robert J. Bowell, Charles N. Alpers, Heather E. Jamieson, D. Kirk Nordstrom, Juraj Majzlan
2014, Reviews in Mineralogy and Geochemistry (79) 1-16
Arsenic is one of the most prevalent toxic elements in the environment. The toxicity, mobility, and fate of arsenic in the environment are determined by a complex series of controls dependent on mineralogy, chemical speciation, and biological processes. The element was first described by Theophrastus in 300 B.C. and named...
Preface
Robert J. Bowell, Charles N. Alpers, Heather E. Jamieson, D. Kirk Nordstrom, Juraj Majzlan
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...
