Watershed modeling applications in south Texas
Diana E. Pedraza, Darwin J. Ockerman
2012, Fact Sheet 2012-3005
Watershed models can be used to simulate natural and human-altered processes including the flow of water and associated transport of sediment, chemicals, nutrients, and microbial organisms within a watershed. Simulation of these processes is useful for addressing a wide range of water-resource challenges, such as quantifying changes in water availability...
Active transtensional intracontinental basins: Walker Lane in the western Great Basin
Angela S. Jayko, Marcus Bursik
2012, Book chapter, Tectonics of Sedimentary Basins: Recent Advances
The geometry and dimensions of sedimentary basins within the Walker Lane are a result of Plio-Pleistocene transtensive deformation and partial detachment of the Sierra Nevada crustal block from the North American plate. Distinct morpho-tectonic domains lie within this active transtensive zone. The northeast end of the Walker Lane is partly...
Carbonate aquifers

2012, Book, Trace Fossils as Indicators of Sedimentary Environments
Only limited hydrogeological research has been conducted using ichnology in carbonate aquifer characterization. Regardless, important applications of ichnology to carbonate aquifer characterization include its use to distinguish and delineate depositional cycles, correlate mappable biogenically altered surfaces, identify zones of preferential groundwater flow and paleogroundwater flow, and better understand the origin...

Kimberly R. Guilbault, C. S. Brown, Jonathan M. Friedman, P.B. Shafroth
2012, Biological Invasions (14) 1711-1724
Russian olive (Elaeagnus angustifolia L.), a Eurasian tree now abundant along rivers in western North America, has an apparent southern distribution limit running through southern California, Arizona, New Mexico and Texas. We used field observations to precisely define this limit in relation to temperature variables. We then investigated...

2012, Open-File Report 2012-1001
A series of in-stream passive integrated transponder (PIT) detection antennas installed across the Klamath River in August 2010 were tested using tagged fish in the summer of 2011. Six pass-by antennas were constructed and anchored to the bottom of the Klamath River at a site between the Shasta and Scott...
Metformin prevents endoplasmic reticulum stress-induced apoptosis through AMPK-PI3K-c-Jun NH2 pathway
T.W. Jung, Myung W. Lee, Y.-J. Lee, S.M. Kim
2012, Biochemical and Biophysical Research Communications (417) 147-152
Type 2 diabetes mellitus is thought to be partially associated with endoplasmic reticulum (ER) stress toxicity on pancreatic beta cells and the result of decreased insulin synthesis and secretion. In this study, we showed that a well-known insulin sensitizer, metformin, directly protects against dysfunction and death of ER stress-induced NIT-1...

Christine M. Moffitt, Christopher A. James
2012, Freshwater Science (31) 1035-1041
We explored the resilience of the invasive New Zealand mudsnail Potamopyrgus antipodarum to fluctuating winter freezing and near-freezing temperature cycles in laboratory tests. Our goal was to provide data to confirm field observations of mortality and presumed mortality in stream habitats with fluctuating freezing to near-freezing temperatures. We tested individuals...

Movement and feeding ecology of recently emerged steelhead in Lake Ontario tributaries
James H. Johnson, James E. McKenna Jr., Kevin A. Douglass
2012, Journal of Applied Ichthyology (29) 221-225
Steelhead (Oncorhynchus mykiss) ascend several Lake Ontario tributaries to spawn and juveniles are often the most abundant salmonid where spawning is successful. Movement and diet of recently emerged subyearling steelhead were examined in three New York tributaries of Lake Ontario. Downstream movement occurred mainly at night and consisted of significantly...
Will hunters steward wolves? A comment on Treves and Martin
Jeremy T. Bruskotter, David C. Fulton
2012, Society & Natural Resources: An International Journal (25) 97-102
As wolf conservation transitions away from federally sponsored protection and recovery toward sustainable management under state fish and game agencies, researchers and policymakers are interested to know what role hunters will play. Based upon hunters' responses to three recent surveys in Wisconsin and the northern Rockies, Treves and Martin question...
Anaerobic oxidation of arsenite by autotrophic bacteria: The view from Mono Lake, California
Ronald S. Oremland, John F. Stolz, Chad W. Saltikov
Joanne M. Santini, Seamus A. Ward, editor(s)
2012, Book chapter, The metabolism of arsenite
Introduction The phenomenon of arsenite [As(III)] oxidation by aerobic bacteria was first reported by Green (1918), and the many subsequent discoveries made in this realm, most occurring over the past three decades, are the primary focus of this book. In contrast, the fact that select anaerobes can also achieve this feat...

Effects of acoustic deterrents on foraging bats
Joshua B. Johnson, W. Mark Ford, Jane L. Rodrigue, John W. Edwards
2012, Research Note NRS-129
Significant bat mortality events associated with wind energy expansion, particularly in the Appalachians, have highlighted the need for development of possible mitigation practices to reduce or prevent strike mortality. Other than increasing turbine cut-in speed, acoustic deterrents probably hold the greatest promise for reducing bat mortality. However, acoustic deterrent effectiveness...

George R. Zug, Robert N. Fisher
2012, Zootaxa (3257) 22-37
The Slender-toed Geckos (Nactus) currently have four recognized species in New Guinea, and these species divide into two sister clades: a pelagicus clade and a vankampeni clade (Heinicke et al. 2010). The latter contains three dwarf species. The former consists of five bisexual populations, of which numerous New Guinea populations...
