Measuring the relative resilience of subarctic lakes to global change: redundancies of functions within and across temporal scales
David G. Angeler, Craig R. Allen, Richard K. Johnson
2013, Journal of Applied Ecology (50) 572-584
1. Ecosystems at high altitudes and latitudes are expected to be particularly vulnerable to the effects of global change. We assessed the responses of littoral invertebrate communities to changing abiotic conditions in subarctic Swedish lakes with long-term data (1988–2010) and compared the responses of subarctic lakes with those of more...
Introduction to the special issue on “Understanding and predicting change in the coastal ecosystems of the northern Gulf of Mexico”
John Brock, John A. Barras, S. Jeffress Williams
2013, Journal of Coastal Research (63) 1-5
The coastal region of the northern Gulf of Mexico owes its current landscape structure to an array of tectonic, erosional and depositional, climatic, geochemical, hydrological, ecological, and human processes that have resulted in some of the world's most complex, dynamic, productive, and threatened ecosystems. Catastrophic hurricane landfalls, ongoing subsidence and...

Christopher T. Mills, Gregory F. Slater, Robert F. Dias, Stephanie A. Carr, Christopher M. Reddy, Raleigh Schmidt, Kevin W. Mandernack
2013, FEMS Microbiology Ecology (84) 474-494
Seepage of coal-bed methane (CBM) through soils is a potential source of atmospheric CH4 and also a likely source of ancient (i.e. 14C-dead) carbon to soil microbial communities. Natural abundance 13C and 14C compositions of bacterial membrane phospholipid fatty acids (PLFAs) and soil gas CO2 and CH4 were used to...

2013, Archives of Environmental Contamination and Toxicology (65) 598-610
Mining and smelting in the Southeast Missouri Lead Mining District has caused widespread contamination of soils with lead (Pb) and other metals. Soils from three study sites sampled in the district contained from approximately 1,000–3,200 mg Pb/kg. Analyses of earthworms [33–4,600 mg Pb/kg dry weight (dw)] collected in the district...
Water-level altitudes 2013 and water-level changes in the Chicot, Evangeline, and Jasper aquifers and compaction 1973--2012 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
Mark C. Kasmarek, Michaela R. Johnson, Jason K. Ramage
2013, Scientific Investigations Map 3263
Most of the 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 mostly in the clay and silt layers of the aquifer sediments....

George M. Durner, Kristin S. Simac, Steven C. Amstrup
2013, Arctic (66) 139-245
The National Petroleum Reserve–Alaska (NPR-A) in northeastern Alaska provides winter maternal denning habitat for polar bears (Ursus maritimus) and also has high potential for recoverable hydrocarbons. Denning polar bears exposed to human activities may abandon their dens before their young are able to survive the severity of Arctic winter weather....

Linking morphodynamic response with sediment mass balance on the Colorado River in Marble Canyon: issues of scale, geomorphic setting, and sampling design
Paul E. Grams, David J. Topping, John C. Schmidt, Joseph E. Hazel Jr., Matt Kaplinski
2013, Journal of Geophysical Research F: Earth Surface (118) 361-381
Measurements of morphologic change are often used to infer sediment mass balance. Such measurements may, however, result in gross errors when morphologic changes over short reaches are extrapolated to predict changes in sediment mass balance for long river segments. This issue is investigated by examination of morphologic change and sediment...

Environmental DNA as a new method for early detection of New Zealand mudsnails (Potamopyrgus antipodarum)
Caren S. Goldberg, Adam Sepulveda, Andrew Ray, Jeremy A. Baumgardt, Lisette P. Waits
2013, Freshwater Science (32) 792-800
Early detection of aquatic invasive species is a critical task for management of aquatic ecosystems. This task is hindered by the difficulty and cost of surveying aquatic systems thoroughly. The New Zealand mudsnail (Potamopyrgus antipodarum) is a small, invasive parthenogenic mollusk that can reach very high population densities and severely...

H. River Gates, Richard B. Lanctot, Abby N. Powell
2013, The Auk (130) 372-380
The propensity to replace a clutch is a complex component of avian reproduction and poorly understood. We experimentally removed clutches from an Arctic-breeding shorebird, the Dunlin (Calidris alpina arcticola), during early and late stages of incubation to investigate replacement clutch rates, renesting interval, and mate and site fidelity between nesting...

Kendal E. Young, Laurie B. Abbott, Colleen A. Caldwell, T. Scott Schrader
2013, International Journal of Biodiversity and Conservation (5) 122-134
The key to reducing ecological and economic damage caused by invasive plant species is to locate and eradicate new invasions before they threaten native biodiversity and ecological processes. We used Landsat Enhanced Thematic Mapper Plus imagery to estimate suitable environments for four invasive plants in Big Bend National Park, southwest...
