This paper contains the results of an extensive isotopic study of United States Geological Survey GSD-1G and MPI-DING reference glasses. Thirteen different laboratories were involved using high-precision bulk (TIMS, MC-ICP-MS) and microanalytical (LA-MC-ICP-MS, LA-ICP-MS) techniques. Detailed studies were performed to demonstrate the large-scale and small-scale homogeneity of the reference glasses....

2011, Journal of Mammalogy (92) 534-543
A trade-off exists for migrating animals as to whether to migrate or remain residents. Few studies have documented relationships between landscape variables and deer migration strategies. From 2000 to 2007 we captured 267 adult female white-tailed deer (Odocoileus virginianus) at 7 study sites in Minnesota and South Dakota and monitored...
An 1800-yr record of decadal-scale hydroclimatic variability in the upper Arkansas River basin from bristlecone pine
C.A. Woodhouse, G.T. Pederson, S.T. Gray
2011, Quaternary Research (75) 483-490
Bristlecone pine trees are exceptionally long-lived, and with the incorporation of remnant material have been used to construct multi-millennial length ring-width chronologies. These chronologies can provide valuable information about past temperature and moisture variability. In this study, we outline a method to build a moisture-sensitive bristlecone chronology and assess the...

Patrick M. McElhone, Petra B. Wood, Deanna K. Dawson
2011, Wilson Journal of Ornithology (123) 699-708
- We examined the effects of habitat change on Cerulean Warbler ( Dendroica cerulea) populations at stops along Breeding Bird Survey (BBS) routes in the central Appalachians. We used aerial photographs to compare early (1967/1971), middle (1982/1985), and late (2000/2003) periods and compared 1992 and 2001 National Land Cover...

2011, Ground Water (49) 593-599
NETPATH-WIN is an interactive user version of NETPATH, an inverse geochemical modeling code used to find mass-balance reaction models that are consistent with the observed chemical and isotopic composition of waters from aquatic systems. NETPATH-WIN was constructed to migrate NETPATH applications into the Microsoft WINDOWS® environment. The new version facilitates...
Millennial precipitation reconstruction for the Jemez Mountains, New Mexico, reveals changing drought signal
Ramzi Touchan, Connie A. Woodhouse, David M. Meko, Craig D. Allen
2011, International Journal of Climatology (31) 896-906
Drought is a recurring phenomenon in the American Southwest. Since the frequency and severity of hydrologic droughts and other hydroclimatic events are of critical importance to the ecology and rapidly growing human population of this region, knowledge of long-term natural hydroclimatic variability is valuable for resource managers and policy-makers. An...

Chronic toxicity of erythromycin thiocyanate to Daphnia magna in a flow-through, continuous exposure test system
J.R. Meinertz, Theresa M. Schreier, J.A. Bernardy
2011, Bulletin of Environmental Contamination and Toxicology (87) 621-625
Approval of a new animal drug application for AQUAMYCIN 100® (erythromycin thiocyanate; ET) to treat freshwater salmonid species with bacterial kidney disease is being pursued in the US. As part of the approval process, ET’s impact on an aquatic environment had to be described in an environmental assessment. The environmental assessment...

G.B. Senay, S. Leake, P.L. Nagler, G. Artan, J. Dickinson, J.T. Cordova, E. P. Glenn
2011, Hydrological Processes (25) 4037-4049
Evapotranspiration (ET) is an important hydrological process that can be studied and estimated at multiple spatial scales ranging from a leaf to a river basin. We present a review of methods in estimating basin scale ET and its applications in understanding basin water balance dynamics. The review focuses on two...
The influence of fine-scale habitat features on regional variation in population performance of alpine White-tailed Ptarmigan
B. Fedy, K. Martin
2011, Condor (113) 306-315
It is often assumed (explicitly or implicitly) that animals select habitat features to maximize fitness. However, there is often a mismatch between preferred habitats and indices of individual and population measures of performance. We examined the influence of fine-scale habitat selection on the overall population performance of the White-tailed Ptarmigan...

B.J. Mattsson, S.C. Latta, R.J. Cooper, R.S. Mulvihill
2011, Condor (113) 412-418
We evaluated hypotheses that seek to explain breeding strategies of the Louisiana Waterthrush (Parkesia motacilla) that vary across a latitudinal gradient. On the basis of data from 418 nests of color-banded individuals in southwestern Pennsylvania and 700 km south in the Georgia Piedmont, we found that clutch size in replacement...
Survival of European mouflon (Artiodactyla: Bovidae) in Hawai'i based on tooth cementum lines
S.C. Hess, R.M. Stephens, T.L. Thompson, R.M. Danner, B. Kawakami Jr.
2011, Pacific Science (65) 59-67
Reliable techniques for estimating age of ungulates are necessary to determine population parameters such as age structure and survival. Techniques that rely on dentition, horn, and facial patterns have limited utility for European mouflon sheep (Ovis gmelini musimon), but tooth cementum lines may offer a useful alternative. Cementum lines may...

Craig R. Allen, J.J. Fontaine, K.L. Pope, A.S. Garmestani
2011, Journal of Environmental Management (92) 1339-1345
The challenges that face humanity today differ from the past because as the scale of human influence has increased, our biggest challenges have become global in nature, and formerly local problems that could be addressed by shifting populations or switching resources, now aggregate (i.e., "scale up") limiting potential management options....

2011, Marine Pollution Bulletin (62) 2308-2316
Water, sponge and coral samples were collected from stations impacted by a variety of pollution sources and screened for human enteric viruses as conservative markers for human sewage. While human enteroviruses and adenoviruses were not detected, noroviruses (NoV; human genogroups I and II) were detected in 31% of samples (especially...

After submitting that work to SC11...
Evaluating cost-efficiency and accuracy of hunter harvest survey designs
P.M. Lukacs, J.A. Gude, R.E. Russell, B.B. Ackerman
2011, Wildlife Society Bulletin (35) 430-437
Effective management of harvested wildlife often requires accurate estimates of the number of animals harvested annually by hunters. A variety of techniques exist to obtain harvest data, such as hunter surveys, check stations, mandatory reporting requirements, and voluntary reporting of harvest. Agencies responsible for managing harvested wildlife such as deer...
Simulating sterilization, vaccination, and test-and-remove as brucellosis control measures in bison
M. Ebinger, Paul C. Cross, Rick Wallen, P.J. White, John Treanor
2011, Ecological Applications (21) 2944-2959
Brucella abortus, the causative agent of bovine brucellosis, infects wildlife, cattle, and humans worldwide, but management of the disease is often hindered by the logistics of controlling its prevalence in wildlife reservoirs. We used an individually based epidemiological model to assess the relative efficacies of three management interventions (sterilization, vaccination,...
From agricultural intensification to conservation: Sediment transport in the Raccoon River, Iowa, 1916-2009
C.S. Jones, K. E. Schilling
2011, Journal of Environmental Quality (40) 1911-1923
Fluvial sediment is a ubiquitous pollutant that negatively aff ects surface water quality and municipal water supply treatment. As part of its routine water supply monitoring, the Des Moines Water Works (DMWW) has been measuring turbidity daily in the Raccoon River since 1916. For this study, we calibrated daily turbidity...
Effects of human-induced alteration of groundwater flow on concentrations of naturally-occurring trace elements at water-supply wells
J. D. Ayotte, Z. Szabo, M. J. Focazio, S. M. Eberts
2011, Applied Geochemistry (26) 747-762
The effects of human-induced alteration of groundwater flow patterns on concentrations of naturally-occurring trace elements were examined in five hydrologically distinct aquifer systems in the USA. Although naturally occurring, these trace elements can exceed concentrations that are considered harmful to human health. The results show that pumping-induced hydraulic gradient changes...
An inexpensive instrument for measuring wave exposure and water velocity
J.D. Figurski, D. Malone, J.R. Lacy, M. Denny
2011, Limnology and Oceanography: Methods (9) 204-214
Ocean waves drive a wide variety of nearshore physical processes, structuring entire ecosystems through their direct and indirect effects on the settlement, behavior, and survivorship of marine organisms. However, wave exposure remains difficult and expensive to measure. Here, we report on an inexpensive and easily constructed instrument for measuring wave-induced...
