Marci M. Robinson, Harry J. Dowsett
2010, Stratigraphy (7) 177-187
As part of the Pliocene Research, Interpretation and Synoptic Mapping (PRISM) Project, we present the ePRISM experiment designed I) to provide climate modelers with a reconstruction of an early Pliocene warm period that was warmer than the PRISM interval (similar to 3.3 to 3.0 Ma), yet still similar in many...
Predators shape distribution and promote diversification of morphological defenses in Leucorrhinia , Odonata
Zlatko Petrin, Emily Gaenzle Schilling, Cyndy Loftin, Frank Johansson
2010, Evolutionary Ecology (24) 1003-1016
Predators strongly influence species assemblages and shape morphological defenses of prey. Interestingly, adaptations that constitute effective defenses against one type of predator may render the prey susceptible to other types of predators. Hence, prey may evolve different strategies to escape predation, which may facilitate adaptive radiation of prey organisms. Larvae...

K. White, J. Gerken, Craig P. Paukert, Andrew S. Makinster
2010, River Research and Applications (26) 797-805
We investigated fish assemblage structure in engineered (rip‐rap) and natural habitats (log jams and mud banks) in the Kansas River USA to determine if natural structures had higher abundance and diversity of fishes at a local spatial scale. A total of 439 randomly selected sites were boat electrofished from May...
The effect of resource quantity and resource stoichiometry on microbial carbon-use-efficiency
K.M. Kleiblinger, E. K. Hall, W. Wanek, U. Szukics, I. Hammerle, G. Ellersdorfer, S. Bock, J. Strauss, K. Sterflinger, A. Richter, S. Zechmeister-Boltenstern
2010, FEMS Microbiology Ecology (73) 430-440
The carbon-use-efficiency (CUE) of microorganisms is an important parameter in determining ecosystem-level carbon (C) cycling; however, little is known about how variance in resources affects microbial CUE. To elucidate how resource quantity and resource stoichiometry affect microbial CUE, we cultured four microorganisms - two fungi (Aspergillus nidulans and Trichoderma harzianum)...
Wolves will not provide small-scale ecological restoration
Jerrold L. Belant, Layne G. Adams
2010, BioScience (60) 485-485
Licht and colleagues (BioScience 60: 147–153) proposed a paradigm shift in wolf management to include the introductions of small, highly manipulated groups of wolves (Canis lupus) to confined natural areas to facilitate ecosystem recovery. Certainly, reductions or losses of apex predators from many regions worldwide have had profound effects on...

Effects of low-impact-development (LID) practices on streamflow, runoff quantity, and runoff quality in the Ipswich River Basin, Massachusetts: A summary of field and modeling studies
Marc J. Zimmerman, Marcus C. Waldron, Jeffrey R. Barbaro, Jason R. Sorenson
2010, Circular 1361
Low-impact-development (LID) approaches are intended to create, retain, or restore natural hydrologic and water-quality conditions that may be affected by human alterations. Wide-scale implementation of LID techniques may offer the possibility of improving conditions in river basins, such as the Ipswich River Basin in Massachusetts, that have run dry during...
Global building inventory for earthquake loss estimation and risk management

2010, Earthquake Spectra (26) 731-748
We develop a global database of building inventories using taxonomy of global building types for use in near-real-time post-earthquake loss estimation and pre-earthquake risk analysis, for the U.S. Geological Survey’s Prompt Assessment of Global Earthquakes for Response (PAGER) program. The database is available for public use, subject to peer review,...
King eider use an income strategy for egg production: a case study for incorporating individual dietary variation into nutrient allocation research
Steffen Oppel, Abby N. Powell, Diane M. O’Brien
2010, Oecologia (164) 1-12
The use of stored nutrients for reproduction represents an important component of life-history variation. Recent studies from several species have used stable isotopes to estimate the reliance on stored body reserves in reproduction. Such approaches rely on population-level dietary endpoints to characterize stored reserves (“capital”) and current diet (“income”). Individual...

2010, Hydrogeology Journal (18) 1539-1545
A frequency-domain electromagnetic (FDEM) survey can be used to select locations for the more quantitative and labor-intensive electrical resistivity surveys. The FDEM survey rapidly characterized the groundwater-flow directions and configured the saline plumes caused by evaporation from several groundwater-dominated lakes in the Nebraska Sand Hills, USA. The FDEM instrument was...
