Time constraints in temperate-breeding species: Influence of growing season length on reproductive strategies
K. E. B. Gurney, Russell G. Clark, Stuart Slattery, N. V. Smith-Downey, Jordan I. Walker, L. M. Armstrong, S. E. Stephens, Michael J. Petrula, R. M. Corcoran, K. Martin, K. A. Degroot, Rodney W. Brook, Alan D. Afton, K. Cutting, J. M. Warren, M. Fournier, David N. Koons
2011, Ecography (34) 628-636
Organisms that reproduce in temperate regions have limited time to produce offspring successfully, and this constraint is expected to be more pronounced in areas with short growing seasons. Information concerning how reproductive ecology of endotherms might be influenced by growing season length (GSL) is rare, and species that breed over...
Beach characteristics mitigate effects of onshore wind on horseshoe crab spawning: Implications for matching with shorebird migration in Delaware Bay
D. R. Smith, N.L. Jackson, K.F. Nordstrom, R.G. Weber
2011, Animal Conservation (14) 575-584
Disruption of food availability by unfavorable physical processes at energetically demanding times can limit recruitment of migratory species as predicted by the match–mismatch hypothesis. Identification and protection of disruption‐resistant habitat could contribute to system resilience. For example, horseshoe crab Limulus polyphemus spawning and shorebird stopover must match temporally in Delaware Bay for...
New information on the braincase of the North American therizinosaurian (Theropoda, Maniraptora) Falcarius utahensis
David Smith, Lindsay E. Zanno, R. Kent Sanders, Donald D. Deblieux, James I. Kirkland
2011, Journal of Vertebrate Paleontology (31) 387-404
Many disarticulated bones from multiple individuals of a primitive therizinosaurian, referred to Falcarius utahensis, were found in the paucispecific Crystal Geyser bonebed in the Lower Cretaceous Cedar Mountain Formation of eastern Utah. To date, more than 2000 specimens from this species have been excavated. Included in this collection are two partial...

2011, SEG Technical Program Expanded Abstracts (30) 856-860
Aeromagnetic data belonging to the State Company of Geology and Mining of Iraq (GEOSURV) have been recovered from magnetic tapes and early paper maps. In 1974 a national airborne survey was flown by the French firm Compagnie General de Geophysique (CGG). Following the survey the magnetic data were stored on...

Evaluation of single and two-stage adaptive sampling designs for estimation of density and abundance of freshwater mussels in a large river
D. R. Smith, J. T. Rogala, B. R. Gray, S. J. Zigler, T.J. Newton
2011, River Research and Applications (27) 122-133
Reliable estimates of abundance are needed to assess consequences of proposed habitat restoration and enhancement projects on freshwater mussels in the Upper Mississippi River (UMR). Although there is general guidance on sampling techniques for population assessment of freshwater mussels, the actual performance of sampling designs can depend critically on the...

David J. Smith, Dale W. Griffin, Richard D. McPeters, Peter D. Ward, Andrew C. Schuerger
2011, Aerobiologia (27) 319-332
Spores of Bacillus subtilis were exposed to a series of stratosphere simulations. In total, five distinct treatments measured the effect of reduced pressure, low temperature, high desiccation, and intense ultraviolet (UV) irradiation on stratosphereisolated and ground-isolated B. subtilis strains. Environmental conditions were based on springtime data from a mid-latitude region...
The high life: Transport of microbes in the atmosphere
D.J. Smith, Dale W. Griffin, D.A. Jaffe
2011, Eos, Transactions, American Geophysical Union (92) 249-250
Microbes (bacteria, fungi, algae, and viruses) are the most successful types of life on Earth because of their ability to adapt to new environments, reproduce quickly, and disperse globally. Dispersal occurs through a number of vectors, such as migrating animals or the hydrological cycle, but transport by wind may be...
Decision analysis for conservation breeding: Maximizing production for reintroduction of whooping cranes
Des H.V. Smith, Sarah J. Converse, Keith Gibson, Axel Moehrenschlager, William A. Link, Glenn H. Olsen, Kelly Maguire
2011, Journal of Wildlife Management (75) 501-508
Captive breeding is key to management of severely endangered species, but maximizing captive production can be challenging because of poor knowledge of species breeding biology and the complexity of evaluating different management options. In the face of uncertainty and complexity, decision-analytic approaches can be used to identify optimal management options...

D.B. George, C.T. Webb, Matthew L. Farnsworth, T. J. O'Shea, R. A. Bowen, D.L. Smith, T.R. Stanley, L.E. Ellison, C. E. Rupprecht
2011, Proceedings of the National Academy of Sciences of the United States of America (108) 10208-10213
Rabies is an acute viral infection that is typically fatal. Most rabies modeling has focused on disease dynamics and control within terrestrial mammals (e.g., raccoons and foxes). As such, rabies in bats has been largely neglected until recently. Because bats have been implicated as natural reservoirs for several emerging zoonotic...
Classification of MEC with the ALLTEM at Camp Stanley, Texas
T. Asch, C. Moulton, D.V. Smith
2011, SEG Technical Program Expanded Abstracts (30) 1363-1367
The ALLTEM is a multi-axis electromagnetic induction system designed for unexploded ordnance UXO applications. It uses a continuous triangle-wave excitation and provides good late-time signal-to-noise ratio SNR especially for ferrous targets. Multi-axis transmitter Tx and receiver Rx systems such as ALLTEM provide a richer data set from which to invert...
Collection of mammal manure and other Debris by nesting Burrowing Owls
M. D. Smith, C.J. Conway
2011, Journal of Raptor Research (45) 220-228
Burrowing Owls (Athene cunicularia) routinely collect and scatter dry manure of mammals around their nesting burrows. Recent studies have suggested this behavior attracts insect prey to the nesting burrow. However, some Burrowing Owls do not use manure, but instead, collect and scatter other materials (e.g., grass, moss, paper, plastic)...
Groundwater chemistry near an impoundment for produced water, Powder River Basin, Wyoming, USA
R. W. Healy, T.T. Bartos, C. A. Rice, M.P. McKinley, B. D. Smith
2011, Journal of Hydrology (403) 37-48
The Powder River Basin is one of the largest producers of coal-bed natural gas (CBNG) in the United States. An important environmental concern in the Basin is the fate of the large amounts of groundwater extracted during CBNG production. Most of this produced water is disposed of in unlined surface...

Progression of stream bank erosion dudring a large flood, Rio Puerco, New Mexico
Eleanor R. Griffin, J. Dungan Smith, Jonathan M. Friedman, Kirk R. Vincent
2010, Conference Paper, Proceedings of the 2nd Joint Federal Interagency Conference
In August 2006, a large flood following saltcedar control efforts through a 12-km long segment of the Rio Puerco arroyo resulted in extensive lateral erosion of the streambanks. Almost all woody vegetation on the floodplain and channel banks had been killed by aerial spraying with herbicide in September 2003. During...

David R. Smith, L. J. Brousseau, Mary T. Mandt, Michael J. Millard
2010, Current Zoology (56) 563-574
To study horseshoe crab Limulus polyphemus spawning behavior and migration over a large-spatial extent (>100 km), we arrayed fixed station radio receivers throughout Delaware Bay and deployed radio transmitters and archival tags on adult horseshoe crabs prior to their spawning season. We tagged and released 160 females and 60 males in 2004...

David B. Smith, Karl J. Ellefsen, James E. Kilburn
2010, Data Series 520
In 2006, soil samples were collected at 960 sites (1 site per 280 square kilometers) throughout the state of Colorado. These samples were collected from a depth of 0-15 centimeters and, following a near-total multi-acid digestion, were analyzed for a suite of more than 40 major and trace elements. The...

2010, Journal of Fish and Wildlife Management (1) 19-32
We developed components of a decision structure that could be used in an adaptive management framework for responding to invasion of hemlock woolly adelgid Adeleges tsugae on the Cumberland Plateau of northern Tennessee. Hemlock woolly adelgid, an invasive forest pest, was first detected in this area in 2007. We used a structured...

Displaying seismic deaggregation: The importance of the various sources
Warwick D. Smith, Stephen Harmsen
2010, Seismological Research Letters (81) 488-497
Seismic hazard deaggregation has become a standard part of probabilistic seismic hazard assessment (PSHA). The first product of PSHA is calculation of the likely severity of ground motion at a given range of annual probability levels, and this is extremely important for seismic design...
