Fossil pollen assemblages provide information about vegetation dynamics at time scales ranging from centuries to millennia. Pollen-vegetation models and process-based models of dispersal typically assume stable relationships between source vegetation and corresponding pollen in surface sediments, as well as stable parameterizations of dispersal and productivity. These assumptions, however, are...

Donna S. Francy, Amie M.G. Brady, Christopher D. Ecker, Jennifer L. Graham, Erin A. Stelzer, Pamela Struffolino, Keith A. Loftin
2016, Harmful Algae (58) 23-34
Cyanobacterial harmful algal blooms (cyanoHABs) and associated toxins, such as microcystin, are a major global water-quality issue. Water-resource managers need tools to quickly predict when and where toxin-producing cyanoHABs will occur. This could be done by using site-specific models that estimate the potential for elevated toxin concentrations that cause public...
Carbon and oxygen isotopic composition of coal and carbon dioxide derived from laboratory coal combustion: A preliminary study
Peter D. Warwick, Leslie F. Ruppert
2016, International Journal of Coal Geology (166) 128-135
The concentration of carbon dioxide (CO2) in the atmosphere has dramatically increased from the start of the industrial revolution in the mid-1700s to present levels exceeding 400 ppm. Carbon dioxide derived from fossil fuel combustion is a greenhouse gas and a major contributor to on-going climate change. Carbon and oxygen...
Synthesis and revision of the lithostratigraphic groups and formations in the Upper Permian?–Lower Jurassic Newark Supergroup of eastern North America
Robert E. Weems, Lawrence H. Tanner, Spencer G. Lucas
2016, Stratigraphy (13) 111-153
The Upper Permian? - Lower Jurassic Newark Supergroup of eastern North America has a strikingly uniform succession of lithologic units. This uniformity is seen regardless of whether these units are characterized on the basis of their lithostratigraphy, allostratigraphy, biostratigraphy, or chemostratigraphy. After deposition, these units were broken up tectonically and...

2016, Data Series 987
Groundwater quality in the 3,016-square-mile Monterey–Salinas Shallow Aquifer study unit was investigated by the U.S. Geological Survey (USGS) from October 2012 to May 2013 as part of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program’s Priority Basin Project. The GAMA Monterey–Salinas Shallow Aquifer...
The water content of recurring slope lineae on Mars
Christopher S. Edwards, Sylvain Piqueux
2016, Geophysical Research Letters (43) 8912-8919
Observations of recurring slope lineae (RSL) from the High-Resolution Imaging Science Experiment have been interpreted as present-day, seasonally variable liquid water flows; however, orbital spectroscopy has not confirmed the presence of liquid H2O, only hydrated salts. Thermal Emission Imaging System (THEMIS) temperature data and a numerical heat transfer model definitively...

Gretchen H. Roffler, Stephen J. Amish, Seth Smith, Ted F. Cosart, Marty Kardos, Michael K. Schwartz, Gordon Luikart
2016, Molecular Ecology Resources (16) 1147-1164
Identification of genes underlying genomic signatures of natural selection is key to understanding adaptation to local conditions. We used targeted resequencing to identify SNP markers in 5321 candidate adaptive genes associated with known immunological, metabolic and growth functions in ovids and other ungulates. We selectively targeted 8161 exons in protein-coding...

2016, Journal of Crustacean Biology (36) 642-648
Cambarus veteranus Faxon, 1914, a narrow endemic crayfish native to the Upper Guyandotte River Basin (UGB) in West Virginia, USA, was petitioned in 2014 by the United States Fish and Wildlife Service to be listed as endangered, but a status survey was recommended to determine if...
Differential influences of local subpopulations on regional diversity and differentiation for greater sage-grouse (Centrocercus urophasianus)
Jeffery R. Row, Sara J. Oyler-McCance, Brad C. Fedy
2016, Molecular Ecology (25) 4424-4437
The distribution of spatial genetic variation across a region can shape evolutionary dynamics and impact population persistence. Local population dynamics and among-population dispersal rates are strong drivers of this spatial genetic variation, yet for many species we lack a clear understanding of how these population processes interact in space to...
A strategy for recovering continuous behavioral telemetry data from Pacific walruses
Anthony S. Fischbach, Chadwick V. Jay
2016, Wildlife Society Bulletin (40) 599-604
Tracking animal behavior and movement with telemetry sensors can offer substantial insights required for conservation. Yet, the value of data collected by animal-borne telemetry systems is limited by bandwidth constraints. To understand the response of Pacific walruses (Odobenus rosmarus divergens) to rapid changes in sea ice availability, we required continuous...
H9N2 influenza A virus isolated from a Greater White-fronted wild goose (Anser albifrons) in Alaska has a mutation in the PB2 gene, which is associated with pathogenicity in human pandemic 2009 H1N1

2016, Genome Announcements (4)
We report here the genomic sequence of an H9N2 influenza A virus [A/greater white-fronted goose/Alaska/81081/2008 (H9N2)]. This virus shares ≥99.8% identity with a previously reported virus. Both strains contain a G590S mutation in the polymerase basic 2 (PB2) gene, which is a pathogenicity marker in the pandemic 2009 H1N1 virus...

Probabilistic assessment of erosion and flooding risk in the northern Gulf of Mexico
Nathaniel G. Plant, Thomas Wahl, Joseph W. Long
2016, Journal of Geophysical Research C: Oceans (121) 3029-3043
We assess erosion and flooding risk in the northern Gulf of Mexico by identifying interdependencies among oceanographic drivers and probabilistically modeling the resulting potential for coastal change. Wave and water level observations are used to determine relationships between six hydrodynamic parameters that influence total water level and therefore erosion and...

Lutz Breuer, Philipp Kraft, editor(s)
2016, Book chapter, Hydro-ecological modeling
Quantification of streamflow characteristics in ungauged catchments remains a challenge. Hydrological modeling is often used to derive flow time series and to calculate streamflow characteristics for subsequent applications that may differ from those envisioned by the modelers. While the estimation of model parameters for ungauged catchments is a challenging research...

Temperature is better than precipitation as a predictor of plant community assembly across a dryland region
Bradley J. Butterfield, Seth M. Munson
2016, Journal of Vegetation Science (27) 938-947
QuestionHow closely do plant communities track climate? Research suggests that plant species converge toward similar environmental tolerances relative to the environments that they experience. Whether these patterns apply to severe environments or scale up to plant community-level patterns of relative climatic tolerances is poorly understood. Using estimates of species' climatic...
Summer-autumn habitat use of yearling rainbow trout in two streams in the Lake Ontario watershed
James H. Johnson, James E. McKenna Jr., Marc Chalupnicki
2016, Open Fish Science Journal (9) 45-50
Understanding the habitat requirements of salmonids in streams is an important component of fisheries management. We examined the summer and autumn habitat use of yearling Rainbow Trout Oncorhynchus mykiss in relation to available habitat in two streams in the Lake Ontario watershed. Little interstream variation in trout habitat use was...
Approaches to stream solute load estimation for solutes with varying dynamics from five diverse small watershed
Brent T. Aulenbach, Douglas A. Burns, James B. Shanley, Ruth D. Yanai, Kikang Bae, Adam Wild, Yang Yang, Dong Yi
2016, Ecosphere (7)
Estimating streamwater solute loads is a central objective of many water-quality monitoring and research studies, as loads are used to compare with atmospheric inputs, to infer biogeochemical processes, and to assess whether water quality is improving or degrading. In this study, we evaluate loads and associated errors to determine the...

2016, Geomorphology (273) 116-133
In landscapes underlain by ice-rich permafrost, the development of thermokarst landforms can have drastic impacts on ecosystem processes and human infrastructure. Here we describe the distribution of thermokarst landforms in the continuous permafrost zone of Arctic Alaska, analyze linkages to the underlying surficial geology, and discuss the vulnerability of different...
