Landslides Mapped from LIDAR Imagery, Kitsap County, Washington
Jonathan P. McKenna, David J. Lidke, Jeffrey A. Coe
2008, Open-File Report 2008-1292
Landslides are a recurring problem on hillslopes throughout the Puget Lowland, Washington, but can be difficult to identify in the densely forested terrain. However, digital terrain models of the bare-earth surface derived from LIght Detection And Ranging (LIDAR) data express topographic details sufficiently well to identify landslides. Landslides and escarpments...

Earthquakes generated from bedding plane-parallel reverse faults above an active wedge thrust, Seattle fault zone
Harvey Kelsey, Brian L. Sherrod, Alan R. Nelson, Thomas M. Brocher
2008, GSA Bulletin (120) 1581-1597
A key question in earthquake hazard analysis is whether individual faults within fault zones represent independent seismic sources. For the Seattle fault zone, an upper plate structure within the Cascadia convergent margin, evaluating seismic hazard requires understanding how north-side-up, bedding-plane reverse faults, which generate late Holocene fault scarps, interact with...
Arctic climate change and its impacts on the ecology of the North Atlantic

2008, Ecology (89) S24-S38
Arctic climate change from the Paleocene epoch to the present is reconstructed with the objective of assessing its recent and future impacts on the ecology of the North Atlantic. A recurring theme in Earth's paleoclimate record is the importance of the Arctic atmosphere, ocean, and cryosphere in regulating global climate...

Latitudinal variation in cold hardiness in introduced Tamarix and native Populus
Jonathan M. Friedman, James E. Roelle, John F. Gaskin, Alan E. Pepper, James R. Manhart
2008, Evolutionary Applications (1) 598-607
To investigate the evolution of clinal variation in an invasive plant, we compared cold hardiness in the introduced saltcedar (Tamarix ramosissima, Tamarix chinensis, and hybrids) and the native plains cottonwood (Populus deltoidessubsp. monilifera). In a shadehouse in Colorado (41°N), we grew plants collected along a latitudinal gradient in the central...
Effects of environmental factors on incubation patterns of Greater Sage-Grouse
Peter S. Coates, David J. Delehanty
2008, The Condor (110) 627-638
Birds in which only one sex incubates the eggs are often faced with a direct conflict between foraging to meet metabolic needs and incubation. Knowledge of environmental and ecological factors that shape life-history strategies of incubation is limited. We used continuous videography to make precise measurements of female Greater Sage-Grouse...

Results of Gravity Fieldwork Conducted in March 2008 in the Moapa Valley Region of Clark County, Nevada
Daniel S. Scheirer, Arne Dossing Andreasen
2008, Open-File Report 2008-1300
In March 2008, we collected gravity data along 12 traverses across newly-mapped faults in the Moapa Valley region of Clark County, Nevada. In areas crossed by these faults, the traverses provide better definition of the gravity field and, thus, the density structure, than prior gravity observations. Access problems prohibited complete...
