Carson G. Prichard, Edward F. Roseman, Kevin M. Keeler, Timothy P. O’Brien, Stephen C. Riley
2016, Transactions of the American Fisheries Society (145) 1241-1251
Native Bloaters Coregonus hoyi have exhibited multiple strong year-classes since 2005 and now are the most abundant benthopelagic offshore prey fish in Lake Huron, following the crash of nonnative AlewivesAlosa pseudoharengus and substantial declines in nonnative Rainbow Smelt Osmerus mordax. Despite recent recoveries in Bloater abundance, marketable-size (>229 mm) Bloaters...

William B. Monahan, Alyssa Rosemartin, Katharine L. Gerst, Nicholas A. Fisichelli, Toby R. Ault, Mark D. Schwartz, John E. Gross, Jake F. Weltzin
2016, Ecosphere (7) 1-17
Many U.S. national parks are already at the extreme warm end of their historical temperature distributions. With rapidly warming conditions, park resource management will be enhanced by information on seasonality of climate that supports adjustments in the timing of activities such as treating invasive species, operating visitor facilities, and scheduling...

Seed bank and big sagebrush plant community composition in a range margin for big sagebrush
Trace E. Martyn, John B. Bradford, Daniel R. Schlaepfer, Ingrid C. Burke, William K. Laurenroth
2016, Ecosphere (7) 1-11
The potential influence of seed bank composition on range shifts of species due to climate change is unclear. Seed banks can provide a means of both species persistence in an area and local range expansion in the case of increasing habitat suitability, as may occur under future climate change. However,...

William L. Yeck, Matthew Weingarten, Harley M. Benz, Daniel E. McNamara, E. Bergman, R.B Herrmann, Justin L. Rubinstein, Paul S. Earle
2016, Geophysical Research Letters (43) 10,198-10,207
The Mw 5.1 Fairview, Oklahoma, earthquake on 13 February 2016 and its associated seismicity produced the largest moment release in the central and eastern United States since the 2011 Mw 5.7 Prague, Oklahoma, earthquake sequence and is one of the largest earthquakes potentially linked to wastewater injection. This energetic sequence has produced...
News from the seabed: Geological characteristics and resource potential of deep-sea mineral resources
Swen Petersen, Anna Kratschell, Nico Augustin, John Jamieson, James R. Hein, Mark D. Hannington
2016, Marine Policy (70) 175-187
Marine minerals such as manganese nodules, Co-rich ferromanganese crusts, and seafloor massive sulfides are commonly seen as possible future resources that could potentially add to the global raw materials supply. At present, a proper assessment of these resources is not possible due to a severe lack of information regarding their...
Automatic delineation of seacliff limits using lidar-derived high-resolution DEMs in southern California
Monica Palaseanu-Lovejoy, Jeffrey J. Danielson, Cindy A. Thatcher, Amy C. Foxgrover, Patrick L. Barnard, John Brock, Adam Young
2016, Journal of Coastal Research 162-173
Seacliff erosion is a serious hazard with implications for coastal management and is often estimated using successive hand-digitized cliff tops or bases (toe) to assess cliff retreat. Even if efforts are made to standardize manual digitizing and eliminate subjectivity, the delineation of cliffs is time-consuming and depends on the analyst's...
Evaluating land cover influences on model uncertainties—A case study of cropland carbon dynamics in the Mid-Continent Intensive Campaign region
Zhengpeng Li, Shuguang Liu, Xuesong Zhang, Tristram O. West, Stephen M. Ogle, Naijun Zhou
2016, Ecological Modelling (337) 176-187
Quantifying spatial and temporal patterns of carbon sources and sinks and their uncertainties across agriculture-dominated areas remains challenging for understanding regional carbon cycles. Characteristics of local land cover inputs could impact the regional carbon estimates but the effect has not been fully evaluated in the past. Within the North American...
Water-level altitudes 2016 and water-level changes in the Chicot, Evangeline, and Jasper aquifers and compaction 1973–2015 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
Mark C. Kasmarek, Jason K. Ramage, Michaela R. Johnson
2016, Scientific Investigations Map 3365
Most of the land-surface subsidence in the Houston-Galveston region, Texas, has occurred as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use, and irrigation that depressured and dewatered the Chicot and Evangeline aquifers, thereby causing compaction of the aquifer sediments, mostly in the fine-grained silt and...
Effects of water-supply reservoirs on streamflow in Massachusetts
Sara B. Levin
2016, Scientific Investigations Report 2016-5123
State and local water-resource managers need modeling tools to help them manage and protect water-supply resources for both human consumption and ecological needs. The U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, has developed a decision-support tool to estimate the effects of reservoirs on natural streamflow....

Helminth community structure in two species of arctic-breeding waterfowl
Courtney L. Amundson, N.J. Traub, A.J. Smith-Herron, Paul L. Flint
2016, International Journal for Parasitology: Parasites and Wildlife (5) 263-272
Climate change is occurring rapidly at high latitudes, and subsequent changes in parasite communities may have implications for hosts including wildlife and humans. Waterfowl, in particular, harbor numerous parasites and may facilitate parasite movement across broad geographic areas due to migratory movements. However, little is known about helminth community structure...

On the importance of stratigraphic control for vertebrate fossil sites in Channel Islands National Park, California, USA: Examples from new Mammuthus finds on San Miguel Island
Jeffery S. Pigati, Daniel R. Muhs, John P. McGeehin
2016, Quaternary International (443) 129-139
Quaternary vertebrate fossils, most notably mammoth remains, are relatively common on the northern Channel Islands of California. Well-preserved cranial, dental, and appendicular elements of Mammuthus exilis (pygmy mammoth) and Mammuthus columbi (Columbian mammoth) have been recovered from hundreds of localities on the islands during the past half-century or more. Despite...
