2015, Natural Hazards and Earth System Sciences (2) 147-162
We evaluated the spatial and seasonal responses of precipitation in the Ganges and Brahmaputra basins as modulated by the El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) modes using Global Precipitation Climatology Centre (GPCC) full data reanalysis of monthly global land-surface precipitation data from 1901 to 2010...
Vegetation controls on weathering intensity during the last deglacial transition in southeast Africa
Sarah J. Ivory, Michael M. McGlue, Geoffrey S. Ellis, Anne-Marie Lézine, Andrew S. Cohen, Annie Vincens
2015, PLoS ONE (9)
Tropical climate is rapidly changing, but the effects of these changes on the geosphere are unknown, despite a likelihood of climatically-induced changes on weathering and erosion. The lack of long, continuous paleo-records prevents an examination of terrestrial responses to climate change with sufficient detail to answer questions about how systems...
Pronounced chemical response of Subarctic lakes to climate-driven losses in surface area
Tyler L. Lewis, Mark S. Lindberg, Joel A. Schmutz, Patricia J. Heglund, Jennifer R. Rover, Joshua C. Koch, Mark R. Bertram
2015, Global Change Biology (21) 1140-1152
Losses in lake area have been observed for several Arctic and Subarctic regions in recent decades, with unknown consequences for lake ecosystems. These reductions are primarily attributed to two climate-sensitive mechanisms, both of which may also cause changes in water chemistry: (i) increased imbalance of evaporation relative to inflow, whereby...

Michael C. Hayes, Steve P. Rubin, Reginald R. Reisenbichler, Lisa A. Wetzel
2015, Journal of Fish and Wildlife Management (6) 176-186
Emigration was evaluated for hatchery Chinook salmon (Oncorhynchus tshawytscha) microjacks (age-1 mature males) and immature parr (age-1 juveniles, both sexes) released from both a hatchery and a natural stream (fish released as fry). In the hatchery, volitional releases (∼14 to 15 months post-fertilization) to an adjacent river occurred during October–November....

2015, Journal of Virology (89) 1389-1403
Since 1998, cyclic mortality events in common eiders (Somateria mollissima), numbering in the hundreds to thousands of dead birds, have been documented along the coast of Cape Cod, Massachusetts, USA. Although longitudinal disease investigations have uncovered potential contributing factors responsible for these outbreaks, detecting a primary etiological agent has proven...

Aaron T. Pearse, Gary L. Krapu, David A. Brandt, Glen A. Sargeant
2015, Wildlife Society Bulletin (39) 87-93
The U.S. Fish and Wildlife Service has used spring aerial surveys to estimate numbers of migrating sandhill cranes (Grus canadensis) staging in the Platte River Valley of Nebraska, USA. Resulting estimates index the abundance of the midcontinent sandhill crane population and inform harvest management decisions. However, annual changes in the...

2015, Environmental Management (55) 807-823
It is uncertain how climate change will impact hydrologic drivers of wildlife population dynamics in freshwater wetlands of the Florida Everglades, or how to accommodate this uncertainty in restoration decisions. Using projections of climate scenarios for the year 2060, we evaluated how several possible futures could affect wildlife populations (wading...

Andrew C. Kemp, Christopher E. Bernhardt, Benjamin P. Horton, Robert E. Kopp, Christopher H. Vane, W. Richard Peltier, Andrea D. Hawkes, Jeffrey P. Donnelly, Andrew C. Parnell, Niamh Cahill
2015, Marine Geology (357) 90-100
Late Holocene relative sea-level (RSL) reconstructions can be used to estimate rates of land-level (subsidence or uplift) change and therefore to modify global sea-level projections for regional conditions. These reconstructions also provide the long-term benchmark against which modern trends are compared and an opportunity to understand the response of sea...
Spatiotemporal variation of surface shortwave forcing from fire-induced albedo change in interior Alaska
Shengli Huang, Devendra Dahal, Heping Liu, Suming Jin, Claudia J. Young, Shuang Liu, Shu-Guang Liu
2015, Canadian Journal of Forest Research (45) 276-285
The albedo change caused by both fires and subsequent succession is spatially heterogeneous, leading to the need to assess the spatiotemporal variation of surface shortwave forcing (SSF) as a component to quantify the climate impacts of high-latitude fires. We used an image reconstruction approach to compare postfire albedo with the...
Testing the use of bulk organic δ13C, δ15N, and Corg:Ntot ratios to estimate subsidence during the 1964 great Alaska earthquake
Adrian M. Bender, Robert C. Witter, Matthew Rogers
2015, Quaternary Science Reviews (113) 134-146
During the Mw 9.2 1964 great Alaska earthquake, Turnagain Arm near Girdwood, Alaska subsided 1.7 ± 0.1 m based on pre- and postearthquake leveling. The coseismic subsidence in 1964 caused equivalent sudden relative sea-level (RSL) rise that is stratigraphically preserved as mud-over-peat contacts where intertidal silt buried peaty marsh surfaces. Changes in intertidal microfossil...
Uncertainty estimates in broadband seismometer sensitivities using microseisms
Adam T. Ringler, Tyler L. Storm, Lind S. Gee, Charles R. Hutt, David C. Wilson
2015, Journal of Seismology (19) 317-327
The midband sensitivity of a seismic instrument is one of the fundamental parameters used in published station metadata. Any errors in this value can compromise amplitude estimates in otherwise high-quality data. To estimate an upper bound in the uncertainty of the midband sensitivity for modern broadband instruments, we compare daily...

Permafrost-associated gas hydrate: is it really approximately 1% of the global system?
Carolyn Ruppel
2015, Journal of Chemical & Engineering Data (60) 429-436
Permafrost-associated gas hydrates are often assumed to contain ∼1 % of the global gas-in-place in gas hydrates based on a study26 published over three decades ago. As knowledge of permafrost-associated gas hydrates has grown, it has become clear that many permafrost-associated gas hydrates are inextricably linked to an associated conventional...

Joshua E. Emerson, Stephen M. Bollens, Timothy D. Counihan
2015, Aquatic Invasions (10) 25-40
The Asian copepod Pseudodiaptomus forbesi has recently become established in the Columbia River. However, little is known about its ecology and effects on invaded ecosystems. We undertook a 2-year (July 2009 to June 2011) field study of the mesozooplankton in four reservoirs in the Columbia and Snake Rivers, with...

Colby W. Brungard, Janis L. Boettinger, Michael C. Duniway, Skye A. Wills, Thomas C. Edwards Jr.
2015, Geoderma (239-240) 68-83
Mapping the spatial distribution of soil taxonomic classes is important for informing soil use and management decisions. Digital soil mapping (DSM) can quantitatively predict the spatial distribution of soil taxonomic classes. Key components of DSM are the method and the set of environmental covariates used to predict soil classes. Machine...
User guide to Exploration and Graphics for RivEr Trends (EGRET) and dataRetrieval: R packages for hydrologic data
Robert M. Hirsch, Laura A. De Cicco
2015, Techniques and Methods 4-A10
Evaluating long-term changes in river conditions (water quality and discharge) is an important use of hydrologic data. To carry out such evaluations, the hydrologist needs tools to facilitate several key steps in the process: acquiring the data records from a variety of sources, structuring it in ways that facilitate the...
Ungulate exclusion, conifer thinning and mule deer forage in northeastern New Mexico
David W. Kramer, Grant E. Sorensen, Chase A. Taylor, Robert D. Cox, Philip S. Gipson, James W. Cain III
2015, Journal of Arid Environments (113) 29-34
The southwestern United States has experienced expansion of conifer species (Juniperus spp. and Pinus ponderosa) into areas of semi-arid grassland over the past century. The expansion of conifers can limit palatable forage and reduce grass and forb communities. Conifer species are sometimes thinned through hydraulic mulching or selective cutting. We...
Development of a spatially universal framework for classifying stream assemblages with application to conservation planning for Great Lakes lotic fish communities
James E. McKenna Jr., Jeffrey S. Schaeffer, Jana S. Stewart, Michael T. Slattery
2015, Restoration Ecology (23) 167-178
Classifications are typically specific to particular issues or areas, leading to patchworks of subjectively defined spatial units. Stream conservation is hindered by the lack of a universal habitat classification system and would benefit from an independent hydrology-guided spatial framework of units encompassing all aquatic habitats at multiple spatial scales within...
