Insights and issues with simulating terrestrial DOC loading of Arctic river networks
David W. Kicklighter, Daniel J. Hayes, James W. McClelland, Bruce J. Peterson, A. David McGuire, Jerry M. Melillo
2013, Ecological Applications (23) 1817-1836
Terrestrial carbon dynamics influence the contribution of dissolved organic carbon (DOC) to river networks in addition to hydrology. In this study, we use a biogeochemical process model to simulate the lateral transfer of DOC from land to the Arctic Ocean via riverine transport. We estimate that, over the 20th century,...

Philip J. Ward, S. Eisner, M. Florke, Michael D. Dettinger, M. Kummu
2013, Hydrology and Earth System Sciences (18) 47-66
Floods are amongst the most dangerous natural hazards in terms of economic damage. Whilst a growing number of studies have examined how river floods are influenced by climate change, the role of natural modes of interannual climate variability remains poorly understood. We present the first global assessment of the influence...
Hysteresis of unsaturated hydromechanical properties of a silty soil
Ning Lu, Murat Kaya, Brian D. Collins, Jonathan W. Godt
2013, Journal of Geotechnical and Geoenvironmental Engineering (139) 507-510
Laboratory tests to examine hysteresis in the hydrologic and mechanical properties of partially saturated soils were conducted on six intact specimens collected from a landslide-prone area of Alameda County, California. The results reveal that the pore-size distribution parameter remains statistically unchanged between the wetting and drying paths; however, the wetting...
Shifts in controls on the temporal coherence of throughfall chemical flux in Acadia National Park, Maine, USA
Sarah J. Nelson, Katherine E. Webster, Cynthia S. Loftin, Kathleen C. Weathers
2013, Biogeochemistry (116) 147-160
Major ion and mercury (Hg) inputs to terrestrial ecosystems include both wet and dry deposition (total deposition). Estimating total deposition to sensitive receptor sites is hampered by limited information regarding its spatial heterogeneity and seasonality. We used measurements of throughfall flux, which includes atmospheric inputs to forests and the net...
Distance, dams and drift: What structures populations of an endangered, benthic stream fish?
James H. Roberts, Paul L. Angermeier, Eric M. Hallerman
2013, Freshwater Biology (58) 2050-2064
Spatial population structure plays an important role in species persistence, evolution and conservation. Benthic stream fishes are diverse and frequently imperilled, yet the determinants and spatial scaling of their population structure are understudied. We investigated the range-wide population genetic structure of Roanoke logperch (Percina rex), an endangered, benthic stream fish...

David J. Rosen, Warren C. Conway, David A. Haukos, Amber D. Caskey
2013, Journal of the Botanical Research Institute of Texas (7) 595-602
Saline lakes and freshwater playas form the principal surface hydrological feature of the High Plains of the Southern Great Plains. Saline lakes number less than 50 and historically functioned as discharge wetlands with relatively consistent water availability due to the presence of one or more springs. Currently, less than ten...

In this study, rainfall and snowmelt event loadings of TSS and TP were analyzed for eight agricultural watersheds in Wisconsin, with...
Assessing grain-size correspondence between flow and deposits of controlled floods in the Colorado River, USA
Amy Draut, David M. Rubin
2013, Journal of Sedimentary Research (83) 962-973
Flood-deposited sediment has been used to decipher environmental parameters such as variability in watershed sediment supply, paleoflood hydrology, and channel morphology. It is not well known, however, how accurately the deposits reflect sedimentary processes within the flow, and hence what sampling intensity is needed to decipher records of recent or...

Holocene dynamics of the Florida Everglades with respect to climate, dustfall, and tropical storms
Paul H. Glaser, Barbara C. S. Hansen, Joseph J. Donovan, Thomas J. Givnish, Craig A. Stricker, John C. Volin
2013, Proceedings of the National Academy of Sciences (110) 17211-17216
Aeolian dust is rarely considered an important source for nutrients in large peatlands, which generally develop in moist regions far from the major centers of dust production. As a result, past studies assumed that the Everglades provides a classic example of an originally oligotrophic, P-limited wetland that was subsequently degraded...

Controls on ecosystem and root respiration across a permafrost and wetland gradient in interior Alaska
Nicole A. McConnell, Merritt R. Turetsky, A. David McGuire, Evan S. Kane, Mark P. Waldrop, Jennifer W. Harden
2013, Environmental Research Letters (8)
Permafrost is common to many northern wetlands given the insulation of thick organic soil layers, although soil saturation in wetlands can lead to warmer soils and increased thaw depth. We analyzed five years of soil CO2 fluxes along a wetland gradient that varied in permafrost and soil moisture conditions. We...

Jeffrey S. Deems, Thomas H. Painter, Joseph J. Barsugli, Jayne Belnap, Bradley Udall
2013, Hydrology and Earth System Sciences (17) 4401-4413
The Colorado River provides water to 40 million people in seven western states and two countries and to 5.5 million irrigated acres. The river has long been overallocated. Climate models project runoff losses of 5–20% from the basin by mid-21st century due to human-induced climate change. Recent work has shown...

2013, Journal of Hydrology (519) 3042-3053
Groundwater inflow to a subtropical seepage lake was estimated using a transient isotope-balance approach for a decade (2001–2011) with wet and dry climatic extremes. Lake water δ18O ranged from +0.80 to +3.48 ‰, reflecting the 4 m range in stage. The transient δ18O analysis discerned large differences in semiannual groundwater...
