The elegance of classification lies in its ability to compile and systematize various terminological conventions and masses of information that are unattainable during typical research projects. Imagine a discipline without standards for collection, analysis, and interpretation; unfortunately, that describes much of 20th-century vegetation ecology. With differing methods, how do we...
Optimizing water depth for wetland-dependent wildlife could increase wetland restoration success, water efficiency, and water security
Christopher P. Nadeau, Courtney J. Conway
2015, Restoration Ecology (23) 292-300
Securing water for wetland restoration efforts will be increasingly difficult as human populations demand more water and climate change alters the hydrologic cycle. Minimizing water use at a restoration site could help justify water use to competing users, thereby increasing future water security. Moreover, optimizing water depth for focal species...
Comparison of three preservation techniques for slowing dissolution of calcareous nannofossils in organic rich sediments
Ellen Seefelt, Jean Self-Trail, Arthur P. Schultz
2015, Micropaleontology (61) 149-164
In an attempt to halt or reduce dissolution of calcareous nannofossils in organic and/or pyrite-rich sediments, three different methods of short-term storage preservation were tested for efficacy: vacuum packing, argon gas replacement, and buffered water. Abundance counts of calcareous nannofossil assemblages over a six month period showed that none of...

2015, The Condor (117) 249-255
Radio-transmitters and light-level geolocators are currently small enough for use on songbirds weighing <15 g. Various methods are used to attach these markers to larger songbirds, but with small birds it becomes especially important to minimize marker mass and bird handling time. Here, we offer modifications to harness materials and...
Geolocators on Golden-winged Warblers do not affect migratory ecology
Sean M. Peterson, Henry M. Streby, Gunnar R. Kramer, Justin A. Lehman, David A. Buehler, David E. Andersen
2015, The Condor (117) 256-261
The use of light-level geolocators is increasingly common for connecting breeding and nonbreeding sites and identifying migration routes in birds. Until recently, the mass and size of geolocators precluded their use on songbird species weighing <12 g. Reducing the mass of geolocators, such as by shortening or eliminating the light...

Characterizing ground motions that collapse steel special moment-resisting frames or make them unrepairable
Anna H. Olsen, Thomas H. Heaton, John F. Hall
2015, Earthquake Spectra (31) 813-840
This work applies 64,765 simulated seismic ground motions to four models each of 6- or 20-story, steel special moment-resisting frame buildings. We consider two vector intensity measures and categorize the building response as “collapsed,” “unrepairable,” or “repairable.” We then propose regression models to predict the building responses from the intensity...

John T. Crawford, Mark M. Dornblaser, Emily H. Stanley, David W. Clow, Robert G. Striegl
2015, Journal of Geophysical Research G: Biogeosciences (120) 952-964
Inland waters are an important component of the global carbon cycle through transport, storage, and direct emissions of CO2 and CH4 to the atmosphere. Despite predictions of high physical gas exchange rates due to turbulent flows and ubiquitous supersaturation of CO2—and perhaps also CH4—patterns of gas emissions are essentially undocumented...
