Genetic variation in adaptive traits and seed transfer zones for Pseudoroegneria spicata (bluebunch wheatgrass) in the northwestern United States

Creator:: St. Clair, John Bradley, Kilkenny, Francis F., Johnson, Richard C., Shaw, Nancy L., and Weaver, George
Abstract:: A genecological approach was used to explore genetic variation in adaptive traits in Pseudoroegneria spicata, a key restoration grass, in the intermountain western United States. Common garden experiments were established at three contrasting sites with seedlings from two maternal parents from each of 114 populations along with five commercial releases...

Abstract:: In 2014, the California Current (~28˚–48˚N) saw average, or below average, coastal upwelling and relatively low productivity in most locations, except from 38˚–43˚N during June and July. Chlorophyll-a levels were low throughout spring and summer at most locations, except in a small region around 39˚N. Catches of juvenile rockfish (an...

Abstract:: The state of the California Current System (CCS) since spring 2011 has evolved in response to dissipation of La Niña through spring and summer, resurgence of cooler La Niña conditions in fall and winter, and finally a transition towards ENSO-neutral conditions in spring 2012. The resurgence of La Niña was...

Lack of Neuromuscular Origins of Adaptation After a Long-Term Stretching Program

Creator:: Hayes, Bradley T., Harter, Rod A., Widrick, Jeffrey J., Williams, Daniel P., Hoffman, Mark A., and Hicks-Little, Charlie A.
Abstract:: Context: Static stretching is commonly used during the treatment and rehabilitation of orthopedic injuries to increase joint range of motion (ROM) and muscle flexibility. Understanding the physiological adaptations that occur in the neuromuscular system as a result of long-term stretching may provide insight into the mechanisms responsible for changes in...

Abstract:: In 2013, the California current was dominated by strong coastal upwelling and high productivity. Indices of total cumulative upwelling for particular coastal locations reached some of the highest values on record. Chlorophyll a levels were high throughout spring and summer. Catches of upwelling-related fish species were also high. After a...

Abstract:: This report reviews the state of the California Current System (CCS) between winter 2012 and spring 2013, and includes observations from Washington State to Baja California. During 2012, large-scale climate modes indicated the CCS remained in a cool, productive phase present since 2007. The upwelling season was delayed north of...

Resilience to Stress and Disturbance, and Resistance to Bromus tectorum L. Invasion in Cold Desert Shrublands of Western North America

Creator:: Chambers, Jeanne C., Bradley, Bethany A., Brown, Cynthia S., D'Antonio, Carla, Germino, Matthew J., Grace, James B., Hardegree, Stuart P., Miller, Richard F., and Pyke, David A.
Abstract:: Alien grass invasions in arid and semi-arid ecosystems are resulting in grass–fire cycles and ecosystem-level transformations that severely diminish ecosystem services. Our capacity to address the rapid and complex changes occurring in these ecosystems can be enhanced by developing an understanding of the environmental factors and ecosystem attributes that determine...

Subducted seamounts and recent earthquakes beneath the central Cascadia forearc

Creator:: Tréhu, Anne M., Blakely, Richard J., and Williams, Mark C.
Abstract:: Bathymetry and magnetic anomalies indicate that a seamount on the Juan de Fuca plate has been subducted beneath the central Cascadia accretionary complex and is now located similar to 45 km landward of the deformation front. Passage of this seamount through the accretionary complex has resulted in a pattern of...

Abstract:: The cause of warming in the Southern Hemisphere during the most recent deglaciation remains a matter of debate[superscript 1,2]. Hypotheses for a Northern Hemisphere trigger, through oceanic redistributions of heat, are based in part on the abrupt onset of warming seen in East Antarctic ice cores and dated to 18,000...

Automated and Accurate Estimation of Gene Family Abundance from Shotgun Metagenomes

Creator:: Nayfach, Stephen, Bradley, Patrick H., Wyman, Stacia K., Laurent, Timothy J., Williams, Alex, Eisen, Jonathan A., Pollard, Katherine S., and Sharpton, Thomas J.
Abstract:: Shotgun metagenomic DNA sequencing is a widely applicable tool for characterizing the functions that are encoded by microbial communities. Several bioinformatic tools can be used to functionally annotate metagenomes, allowing researchers to draw inferences about the functional potential of the community and to identify putative functional biomarkers. However, little is...
