Byron A. Steinman, Mark B. Abbott, Michael E. Mann, Joseph D. Ortiz, Song Feng, David P. Pompeani, Nathan D. Stansell, Lesleigh Anderson, Bruce P. Finney, Broxton W. Bird
2014, Geophysical Research Letters (41) 2553-2560
Reconstructing centennial timescale hydroclimate variability during the late Holocene is critically important for understanding large-scale patterns of drought and their relationship with climate dynamics. We present sediment oxygen isotope records spanning the last two millennia from 10 lakes, as well as climate model simulations, indicating that the Little Ice Age...
Accounting for unsearched areas in estimating wind turbine-caused fatality
Manuela M.P. Huso, Dan Dalthorp
2014, Journal of Wildlife Management (78) 347-358
With wind energy production expanding rapidly, concerns about turbine-induced bird and bat fatality have grown and the demand for accurate estimation of fatality is increasing. Estimation typically involves counting carcasses observed below turbines and adjusting counts by estimated detection probabilities. Three primary sources of imperfect detection are 1) carcasses fall...
Modeling marbled murrelet (Brachyramphus marmoratus) habitat using LiDAR-derived canopy data
Joan C. Hagar, Bianca Eskelson, Patricia K. Haggerty, S. Kim Nelson, David G. Vesely
2014, Wildlife Society Bulletin (38) 237-249
LiDAR (Light Detection And Ranging) is an emerging remote-sensing tool that can provide fine-scale data describing vertical complexity of vegetation relevant to species that are responsive to forest structure. We used LiDAR data to estimate occupancy probability for the federally threatened marbled murrelet (Brachyramphus marmoratus) in the Oregon Coast Range...

Jesse E. Dickinson, Randall T. Hanson, Steven K. Predmore
2014, Techniques and Methods 4-A9
The potential consequences of climate variability and climate change have been identified as major issues for the sustainability and availability of the worldwide water resources. Unlike global climate change, climate variability represents deviations from the long-term state of the climate over periods of a few years to several decades. Currently,...
Simulation of groundwater flow in the "1,500-foot" sand and "2,000-foot" sand, with scenarios to mitigate saltwater migration in the "2,000-foot" sand of the Baton Rouge area, Louisiana
Charles E. Heywood, Jason M. Griffith, John K. Lovelace
2014, Scientific Investigations Report 2013-5227
Groundwater withdrawals have caused saltwater to encroach into freshwater-bearing aquifers beneath Baton Rouge, Louisiana. Groundwater investigations in the 1960s identified a freshwater-saltwater interface located at the Baton Rouge Fault, across which abrupt changes in water levels occur. Aquifers south of the fault generally contain saltwater, and aquifers north of the...

Jennifer L. Lewicki, George E. Hilley, David R. Shelly, John C. King, John P. McGeehin, Margaret T. Mangan, William C. Evans
2014, Earth and Planetary Science Letters (390) 52-58
Unrest at Mammoth Mountain over the past several decades, manifest by seismicity, ground deformation, diffuse CO2 emissions, and elevated 3He/4He ratios in fumarolic gases has been driven by the release of CO2-rich fluids from basaltic intrusions in the middle to lower crust. Recent unrest included the occurrence of three lower-crustal...

Morgan P. Moschetti, Charles S. Mueller, Oliver S. Boyd, Mark D. Petersen
2014, Book, American Geophysical Union, Fall Meeting 2013
In anticipation of the update of the Alaska seismic hazard maps (ASHMs) by the U. S. Geological Survey, we report progress on the comparison of smoothed seismicity models developed using fixed and adaptive smoothing algorithms, and investigate the sensitivity of seismic hazard to the models. While fault-based sources, such as...

Ecological feedbacks can reduce population-level efficacy of wildlife fertility control
Jason I. Ransom, Jenny G. Powers, N. Thompson Hobbs, Dan L. Baker
2014, Journal of Applied Ecology (51) 259-269
1. Anthropogenic stress on natural systems, particularly the fragmentation of landscapes and the extirpation of predators from food webs, has intensified the need to regulate abundance of wildlife populations with management. Controlling population growth using fertility control has been considered for almost four decades, but nearly all research has focused...
Diffuse migratory connectivity in two species of shrubland birds: evidence from stable isotopes
Steven T. Knick, Matthias Leu, John T. Rotenberry, Steven E. Hanser, Kurt Fesenmyer
2014, Oecologia (174) 595-608
Connecting seasonal ranges of migratory birds is important for understanding the annual template of stressors that influence their populations. Brewer’s sparrows (Spizella breweri) and sagebrush sparrows (Artemisiospiza nevadensis) share similar sagebrush (Artemisia spp.) habitats for breeding but have different population trends that might be related to winter location. To link...
Applying downscaled global climate model data to a hydrodynamic surface-water and groundwater model
Eric Swain, Lydia Stefanova, Thomas Smith
2014, American Journal of Climate Change (3) 33-49
Precipitation data from Global Climate Models have been downscaled to smaller regions. Adapting this downscaled precipitation data to a coupled hydrodynamic surface-water/groundwater model of southern Florida allows an examination of future conditions and their effect on groundwater levels, inundation patterns, surface-water stage and flows, and salinity. The downscaled rainfall data...

Biological soil crusts (biocrusts) as a model system in community, landscape and ecosystem ecology
Matthew A. Bowker, Fernando T. Maestre, David Eldridge, Jayne Belnap, Andrea Castillo-Monroy, Cristina Escolar, Santiago Soliveres
2014, Biodiversity and Conservation (23) 1619-1637
Model systems have had a profound influence on the development of ecological theory and general principles. Compared to alternatives, the most effective models share some combination of the following characteristics: simpler, smaller, faster, general, idiosyncratic or manipulable. We argue that biological soil crusts (biocrusts) have unique combinations of these features...

A missing dimension in measures of vaccination impacts
M. Gabriela M. Gomes, Andrew Wargo, Marc Lipsitch, Gael Kurath, Carlota Rebelo, Graham F. Medley, Antonio Coutinho
2014, PLoS Pathogens (10)
Immunological protection, acquired from either natural infection or vaccination, varies among hosts, reflecting underlying biological variation and affecting population-level protection. Owing to the nature of resistance mechanisms, distributions of susceptibility and protection entangle with pathogen dose in a way that can be decoupled by adequately representing the dose dimension. Any...
