David R. Shelly
2010, Nature (463) 648-652
The San Andreas fault is one of the most extensively studied faults in the world, yet its physical character and deformation mode beneath the relatively shallow earthquake-generating portion remain largely unconstrained. Tectonic ‘non-volcanic’ tremor, a recently discovered seismic signal probably generated by shear slip on the deep extension of some major...
Does garbage in diet improve Glaucous Gull reproductive output?
Abby Powell, Emily L. Weiser
2010, Condor (112) 530-538
Anthropogenic subsidies are used by a variety of predators in areas developed for human use or residence. If subsidies promote population growth, these predators can have a negative effect on local prey species. The Glaucous Gull (Larus hyperboreus) is an abundant predator in northern Alaska that is believed to benefit...

The recent increase in dune studies in North America has been heavily focused in the Great Plains, while less attention has historically been given to the dune fields east of the Mississippi River. Here we report ages and suggest a potential sediment source for sand dunes in the Green River...
Theory, methods and tools for determining environmental flows for riparian vegetation: Riparian vegetation-flow response guilds
D.M. Merritt, M. L. Scott, Poff N. Leroy, G.T. Auble, D.A. Lytle
2010, Freshwater Biology (55) 206-225
Riparian vegetation composition, structure and abundance are governed to a large degree by river flow regime and flow-mediated fluvial processes. Streamflow regime exerts selective pressures on riparian vegetation, resulting in adaptations (trait syndromes) to specific flow attributes. Widespread modification of flow regimes by humans has resulted in extensive alteration of...
