The role of uplift and erosion in the persistence of saline groundwater in the shallow subsurface
Richard M. Yager, Kurt J. McCoy, Clifford I. Voss, Ward E. Sanford, Richard B. Winston
2017, Geophysical Research Letters (44) 3672-3681
In many regions of the world, the shallow (<300 m) subsurface is replenished with meteoric recharge within a few centuries or millennia, but in some regions saline groundwater persists despite abundant rainfall. Analyses of the flushing rate of shallow groundwater usually consider the permeability and recharge rate and a static landscape....

David S. Vinson, Neal E. Blair, Anna M. Martini, Steve Larter, William H. Orem, Jennifer C. McIntosh
2017, Chemical Geology (453) 128-145
Stable carbon and hydrogen isotope signatures of methane, water, and inorganic carbon are widely utilized in natural gas systems for distinguishing microbial and thermogenic methane and for delineating methanogenic pathways (acetoclastic, hydrogenotrophic, and/or methylotrophic methanogenesis). Recent studies of coal and shale gas systems have characterized in situ microbial communities...
Classification of California streams using combined deductive and inductive approaches: Setting the foundation for analysis of hydrologic alteration
Matthew I. Pyne, Daren M. Carlisle, Christopher P. Konrad, Eric D. Stein
2017, Ecohydrology (10)
Regional classification of streams is an early step in the Ecological Limits of Hydrologic Alteration framework. Many stream classifications are based on an inductive approach using hydrologic data from minimally disturbed basins, but this approach may underrepresent streams from heavily disturbed basins or sparsely gaged arid regions. An alternative is...

Elizabeth T. Borer, James B. Grace, W. Stanley Harpole, Andrew S. MacDougall, Eric W. Seabloom
2017, Nature Ecology & Evolution (1)
Earth’s biodiversity and carbon uptake by plants, or primary productivity, are intricately interlinked, underlie many essential ecosystem processes, and depend on the interplay among environmental factors, many of which are being changed by human activities. While ecological theory generalizes across taxa and environments, most empirical tests of factors controlling diversity...
Mitigating future avian malaria threats to Hawaiian forest birds from climate change
Wei Liao, Carter T. Atkinson, Dennis LaPointe, Michael D. Samuel
2017, PLoS ONE (12) 1-25
Avian malaria, transmitted by Culex quinquefasciatus mosquitoes in the Hawaiian Islands, has been a primary contributor to population range limitations, declines, and extinctions for many endemic Hawaiian honeycreepers. Avian malaria is strongly influenced by climate; therefore, predicted future changes are expected to expand transmission into higher elevations and intensify and...
