S.B. Lomascolo, A.C. Monmany, A. Malizia, T. E. Martin
2010, Wilson Journal of Ornithology (122) 674-680
We studied the consequences of nest-site choice on nesting success under differing disturbance levels for the Rufous-bellied Thrush (Turdus rufiventris). We compared nest-site choice and nest success between a disturbed site and an undisturbed site in a montane subtropical forest in northwestern Argentina. We found no overall difference in daily...

2010, Environmental Science & Technology (44) 7361-7368
The mixtures of toxins and taste-and-odor compounds present during cyanobacterial blooms are not well characterized and of particular concern when evaluating potential human health risks. Cyanobacterial blooms were sampled in twenty-three Midwestern United States lakes and analyzed for community composition, thirteen cyanotoxins by liquid chromatography/mass spectrometry and immunoassay, and two...

E.M. Glenn, R.G. Anthony, E.D. Forsman
2010, Biological Conservation (143) 2543-2552
We used reverse time capture-mark-recapture models to describe associations between rate of population change (??) and climate for northern spotted owls (Strix occidentalis caurina) at six long-term study areas in Washington and Oregon, USA. Populations in three of six areas showed strong evidence of declining populations, while populations in two...

C.H. Albert, Nigel G. Yoccoz, T.C. Edwards, C.H. Graham, N.E. Zimmermann, W. Thuiller
2010, Ecography (33) 1028-1037
Sampling is a key issue for answering most ecological and evolutionary questions. The importance of developing a rigorous sampling design tailored to specific questions has already been discussed in the ecological and sampling literature and has provided useful tools and recommendations to sample and analyse ecological data. However, sampling issues...

Mingshi Chen, Lijun Mao, Chunguo Zhou, James E. Vogelmann, Zhiliang Zhu
2010, Journal of Environmental Management (91) 2572-2580
Forest loss and fragmentation are of major concern to the international community, in large part because they impact so many important environmental processes. The main objective of this study was to assess the differences in forest fragmentation patterns and drivers between China and the conterminous United States (USA). Using the...

G.L. Robinson, C.J. Conway, C. Kirkpatrick, D.D. Laroche
2010, Wilson Journal of Ornithology (122) 806-809
We attempted to collect diet samples using throat ligatures from nestlings of three songbird species in a riparian woodland in southeastern Arizona from May to August 2009. We had success with Song Sparrows (Melospiza melodia), observed adult Yellow-breasted Chats (Icteria virens) reclaim food from nestlings, and discontinued the use of...
Recruitment of burbot (Lota lota L.) in Lake Erie: An empirical modelling approach
M.A. Stapanian, L.D. Witzel, A. Cook
2010, Ecology of Freshwater Fish (19) 326-337
World-wide, many burbot Lota lota (L.) populations have been extirpated or are otherwise in need of conservation measures. By contrast, burbot made a dramatic recovery in Lake Erie during 1993-2001 but declined during 2002-2007, due in part to a sharp decrease in recruitment. We used Akaike's Information Criterion to evaluate...

Improved hydrogeophysical characterization and monitoring through parallel modeling and inversion of time-domain resistivity andinduced-polarization data
Timothy C. Johnson, Roelof J. Versteeg, Andy Ward, Frederick D. Day-Lewis, André Revil
2010, Geophysics (75) WA27-WA41
Electrical geophysical methods have found wide use in the growing discipline of hydrogeophysics for characterizing the electrical properties of the subsurface and for monitoring subsurface processes in terms of the spatiotemporal changes in subsurface conductivity, chargeability, and source currents they govern. Presently, multichannel and multielectrode data collections systems can collect...
Marine electrical resistivity imaging of submarine groundwater discharge: Sensitivity analysis and application in Waquoit Bay, Massachusetts, USA
Rory Henderson, Frederick D. Day-Lewis, Elena Abarca, Charles F. Harvey, Hanan N. Karam, Lanbo Liu, John W. Lane Jr.
2010, Hydrogeology Journal (18) 173-185
Electrical resistivity imaging has been used in coastal settings to characterize fresh submarine groundwater discharge and the position of the freshwater/salt-water interface because of the relation of bulk electrical conductivity to pore-fluid conductivity, which in turn is a function of salinity. Interpretation of tomograms for hydrologic processes is complicated by...

Restoration and revegetation associated with control of saltcedar and Russian olive: Chapter 7
Patrick B. Shafroth, David M. Merritt, Vanessa B. Beauchamp, Kenneth D. Lair
2010, Book chapter, Saltcedar and Russian Olive Control Demonstration Act Science Assessment (Scientific Investigations Report 2009–5247)
Rationales for controlling or eliminating saltcedar and Russian olive from sites, river reaches, or entire streams include implicit or explicit assumptions that natural recovery or applied restoration of native plant communities will follow exotic plant removal (McDaniel and Taylor, 2003; Quimby and others, 2003). The vegetation that replaces saltcedar and...
Saltcedar and Russian olive interactions with wildlife: Chapter 4
Heather L. Bateman, Eben H. Paxton
2010, Book chapter, Saltcedar and Russian Olive Control Demonstration Act Science Assessment (Scientific Investigations Report 2009–5247)
Riparian areas of flood plains typically provide a mosaic of productive habitats (Stanford and others, 2005; Latterell and others, 2006) capable of supporting many wildlife species, particularly in the arid and semiarid Western United States. The establishment of nonnative invasive plants can alter riparian habitat by inhibiting native plant recruitment...

Pamela L. Nagler, Patrick B. Shafroth, James W. LaBaugh, Keirith A. Snyder, Russell L. Scott, David M. Merritt, John Osterberg
2010, Book chapter, Saltcedar and Russian Olive Control Demonstration Act Science Assessment (Scientific Investigations Report 2009–5247)
This chapter discusses the components of the water budget for a riparian system containing large stands of saltcedar or Russian olive—that is, how water is used by the plant community and how that use affects both streamflow volume and groundwater levels. The relation of water availability to the hydrologic cycle...

2010, Geological Society of America Bulletin (122) 265-281
Late Devonian strata in the eastern United States are generally considered as having been deposited under warm tropical conditions. However, a stratigraphically restricted Late Devonian succession of diamictite- mudstonesandstone within the Spechty Kopf and Rockwell Formations that extends for more than 400 km along depositional strike within the central Appalachian...
Paleomagnetic results from Tertiary volcanic strata and intrusions, Absaroka Volcanic Supergroup, Yellowstone National Park and vicinity: Contributions to the North American apparent polar wander path
S. S. Harlan, L. A. Morgan
2010, Tectonophysics (485) 245-259
We report paleomagnetic and rock magnetic data from volcanic, volcaniclastic, and intrusive rocks of the 55-44Ma Absaroka Volcanic Supergroup (AVS) exposed along the northeastern margin of Yellowstone National Park and adjacent areas. Demagnetization behavior and rock magnetic experiments indicate that the remanence in most samples is carried by low-Ti titanomagnetite,...

2010, Environmental Toxicology and Chemistry (29) 1854-1867
A physiologically based toxicokinetic (PBTK) model was developed to describe the uptake, distribution, and elimination of methylmercury (CH 3Hg) in female American kestrels. The model consists of six tissue compartments corresponding to the brain, liver, kidney, gut, red blood cells, and remaining carcass. Additional compartments describe the elimination of CH3Hg...
Influences of immunocontraception on time budgets, social behavior, and body condition in feral horses
J.I. Ransom, B.S. Cade, N.T. Hobbs
2010, Applied Animal Behaviour Science (124) 51-60
Managers concerned with shrinking habitats and limited resources for wildlife seek effective tools for limiting population growth in some species. Fertility control is one such tool, yet little is known about its impacts on the behavioral ecology of wild, free-roaming animals. We investigated influences of the immunocontraceptive porcine zona pellucida...
