Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. While drylands as a whole are expected to increase in extent and aridity in coming decades, temperature and precipitation forecasts vary by latitude and geographic region suggesting different trajectories for tropical, subtropical, and temperate drylands. Uncertainty in...

Mitchell T. Zischke, David B. Bunnell, Cary D. Troy, Eric K. Berglund, David C. Caroffino, Mark P. Ebener, Ji X. He, Shawn P. Sitar, Tomas O. Hook
2017, Journal of Great Lakes Research (43) 359-369
Spatially separated fish populations may display synchrony in annual recruitment if the factors that drive recruitment success, particularly abiotic factors such as temperature, are synchronised across broad spatial scales. We examined inter-annual variation in recruitment among lake whitefish (Coregonus clupeaformis) populations in lakes Huron, Michigan and Superior using fishery-dependent and...
Reconciling catch differences from multiple fishery independent gill net surveys
Richard T. Kraus, Christopher Vandergoot, Patrick M. Kocovsky, Mark W. Rogers, H. Andrew Cook, Travis O. Brenden
2017, Fisheries Research (188) 17-22
Fishery independent gill net surveys provide valuable demographic information for population assessment and resource management, but relative to net construction, the effects of ancillary species, and environmental variables on focal species catch rates are poorly understood. In response, we conducted comparative deployments with three unique, inter-agency, survey gill nets used...
Restoration handbook for sagebrush steppe ecosystems with emphasis on greater sage-grouse habitat—Part 3. Site level restoration decisions
David A. Pyke, Jeanne C. Chambers, Mike Pellant, Richard F. Miller, Jeffrey L. Beck, Paul S. Doescher, Bruce A. Roundy, Eugene W. Schupp, Steven T. Knick, Mark Brunson, James D. McIver
2017, Circular 1426
Sagebrush steppe ecosystems in the United States currently (2016) occur on only about one-half of their historical land area because of changes in land use, urban growth, and degradation of land, including invasions of non-native plants. The existence of many animal species depends on the existence of sagebrush steppe...

Ecosystem implications of conserving endemic versus eradicating introduced large herbivores in the Galapagos Archipelago
Guillaume Bastille-Rousseau, James P. Gibbs, Karl Campbell, Charles B. Yackulic, Stephen Blake
2017, Biological Conservation (209) 1-10
Restoration of damaged ecosystems through invasive species removal and native species conservation is an increasingly common practice in biodiversity conservation. Estimating the degree of ecosystem response attributable specifically to eradication of exotic herbivores versus restoration of native herbivores is often difficult and is complicated by concurrent temporal changes in other...
Using management to address vegetation stress related to land-use and climate change
Beth A. Middleton, Jere Boudell, Nicholas Fisichelli
2017, Restoration Ecology (25) 326-329
While disturbances such as fire, cutting, and grazing can be an important part of the conservation of natural lands, some adjustments to management designed to mimic natural disturbance may be necessary with ongoing and projected climate change. Stressed vegetation that is incapable of regeneration will be difficult to maintain if...
Climate change and the eco-hydrology of fire: Will area burned increase in a warming western USA?
Donald McKenzie, Jeremy S. Littell
2017, Ecological Applications (27) 26-36
Wildfire area is predicted to increase with global warming. Empirical statistical models and process-based simulations agree almost universally. The key relationship for this unanimity, observed at multiple spatial and temporal scales, is between drought and fire. Predictive models often focus on ecosystems in which this relationship appears to be particularly...

Satellite tracking in marine turtle studies can reveal much about their spatial use of breeding areas, migration zones, and foraging sites. We assessed spatial habitat-use patterns of 10 adult female green turtles (Chelonia mydas) nesting at Buck Island Reef National Monument, U.S. Virgin Islands (BIRNM) from 2011 – 2014....
A regional assessment of chemicals of concern in surface waters of four Midwestern United States national parks
Sarah M. Elliott, David VanderMeulen
2017, Science of the Total Environment (579) 1726-1735
Anthropogenic chemicals and their potential for adverse biological effects raise concern for aquatic ecosystem health in protected areas. During 2013–15, surface waters of four Midwestern United States national parks were sampled and analyzed for wastewater indicators, pharmaceuticals, personal care products, and pesticides. More chemicals and higher concentrations were detected at...
Computer modelling for ecosystem service assessment
Robert Dunford, Paula Harrison, Kenneth J. Bagstad
2017, Book chapter, Mapping ecosystem services
Computer models are simplified representations of the environment that allow biophysical, ecological, and/or socio-economic characteristics to be quantified and explored. Modelling approaches differ from mapping approaches (Chapter 5) as (i) they are not forcibly spatial (although many models do produce spatial outputs); (ii) they focus on understanding and quantifying the...
Improving the Hawaiian seismic network for earthquake early warning
Alicia Hotovec-Ellis, Paul Bodin, Weston Thelen, P. Okubo, John E. Vidale
2017, Seismological Research Letters (88) 326-334
The motivation for earthquake early warning (EEW) is the fact that in many applications a few extra seconds of notice ahead of the about-imminent strong shaking can provide significant benefit. Reducing data latencies, accelerating processing times, and tuning seismic station distributions increase...

2017, Techniques and Methods 6-B35
The Water, Energy, and Biogeochemical Model (WEBMOD) uses the framework of the U.S. Geological Survey (USGS) Modular Modeling System to simulate fluxes of water and solutes through watersheds. WEBMOD divides watersheds into model response units (MRU) where fluxes and reactions are simulated for the following eight hillslope reservoir types: canopy;...
Experts correctly describe demography associated with historical decline of the endangered Indiana bat, but not recent period of stationarity
Wayne E. Thogmartin, Carol A. Sanders-Reed, Jennifer Szymanski, Lori Pruitt, Michael C. Runge
2017, PeerJ (5)
Demographic characteristics of bats are often insufficiently described for modeling populations. In data poor situations, experts are often relied upon for characterizing ecological systems. In concert with the development of a matrix model describing Indiana bat (Myotis sodalis) demography, we elicited estimates for parameterizing this model from 12 experts. We...

2017, Scientific Investigations Report 2016-5172
Increased flows in the San Joaquin River, part of the San Joaquin River Restoration Program, are designed to help restore fish populations. However, increased seepage losses could result from these higher restoration flows, which could exacerbate existing drainage problems in neighboring agricultural lands and potentially damage crops. Channel deposits of...
