Sarah A. Sonsthagen, G. Kevin Sage, Megan C. Fowler, Andrew G. Hope, J.A. Cook, Sandra L. Talbot
2013, Conservation Genetics Resources (5) 315-318
We used next generation shotgun sequencing to develop 21 novel microsatellite markers for the barren-ground shrew (Sorex ugyunak), which were polymorphic among individuals from northern Alaska. The loci displayed moderate allelic diversity (averaging 6.81 alleles per locus) and heterozygosity (averaging 70 %). Two loci deviated from Hardy–Weinberg equilibrium (HWE)...
Accounting for non-photosynthetic vegetation in remote-sensing-based estimates of carbon flux in wetlands
Lisa M. Schile, Kristin B. Byrd, Lisamarie Windham-Myers, Maggi Kelly
2013, Remote Sensing Letters (4) 542-551
Monitoring productivity in coastal wetlands is important due to their high carbon sequestration rates and potential role in climate change mitigation. We tested agricultural- and forest-based methods for estimating the fraction of absorbed photosynthetically active radiation (f APAR), a key parameter for modelling gross primary productivity (GPP), in a restored,...

2013, Deep-Sea Research Part II: Topical Studies in Oceanography (92) 183-188
Relationships among seep community biomass, diversity, and physiographic controls such as underlying geology are not well understood. Previous efforts to constrain these relationships at the Blake Ridge Diapir were limited to observations from piloted deep-submergence vehicles. In August 2012, the autonomous underwater vehicle (AUV) Sentry collected geophysical and photographic data...
Streams in the urban heat island: spatial and temporal variability in temperature
Kayleigh A. Somers, Emily S. Bernhardt, James B. Grace, Brooke A. Hassett, Elizabeth B. Sudduth, Siyi Wang, Dean L. Urban
2013, Freshwater Science (32) 309-326
Streams draining urban heat islands tend to be hotter than rural and forested streams at baseflow because of warmer urban air and ground temperatures, paved surfaces, and decreased riparian canopy. Urban infrastructure efficiently routes runoff over hot impervious surfaces and through storm drains directly into streams and can lead to...

Donald R. Schoolmaster Jr., James B. Grace, E. William Schweiger, Brian R. Mitchell, Glenn R. Guntenspergen
2013, Ecological Indicators (29) 411-419
The development of multimetric indices (MMIs) as a means of providing integrative measures of ecosystem condition is becoming widespread. An increasingly recognized problem for the interpretability of MMIs is controlling for the potentially confounding influences of environmental covariates. Most common approaches to handling covariates are based on simple notions of...

Modeling variably saturated subsurface solute transport with MODFLOW-UZF and MT3DMS
Eric D. Morway, Richard G. Niswonger, Christian D. Langevin, Ryan T. Bailey, Richard W. Healy
2013, Ground Water (51) 237-251
The MT3DMS groundwater solute transport model was modified to simulate solute transport in the unsaturated zone by incorporating the unsaturated-zone flow (UZF1) package developed for MODFLOW. The modified MT3DMS code uses a volume-averaged approach in which Lagrangian-based UZF1 fluid fluxes and storage changes are mapped onto a fixed grid. Referred...
Geological analysis of aeromagnetic data from southwestern Alaska: Implications for exploration in the area of the Pebble porphyry Cu-Au-Mo deposit
Eric D. Anderson, Murray W. Hitzman, Thomas Monecke, Paul A. Bedrosian, Anjana K. Shah, Karen D. Kelley
2013, Economic Geology (108) 421-436
Aeromagnetic data are used to better understand the geology and mineral resources near the Late Cretaceous Pebble porphyry Cu-Au-Mo deposit in southwestern Alaska. The reduced-to-pole (RTP) transformation of regional-scale aeromagnetic data shows that the Pebble deposit is within a cluster of magnetic anomaly highs. Similar to Pebble, the Iliamna, Kijik,...
Using prairie restoration to curtail invasion of Canada thistle: the importance of limiting similarity and seed mix richness
Diane L. Larson, J.B. Bright, Pauline Drobney, Jennifer L. Larson, Nicholas Palaia, Paul A. Rabie, Sara Vacek, Douglas Wells
2013, Biological Invasions (15) 2049-2063
Theory has predicted, and many experimental studies have confirmed, that resident plant species richness is inversely related to invisibility. Likewise, potential invaders that are functionally similar to resident plant species are less likely to invade than are those from different functional groups. Neither of these ideas has been tested in...
