Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

Elliptical borehole enlargements or "breakouts" caused by systematic spalling of a
borehole wall due to regional maximum horizontal stresses were identified in 18 wells
drilled in the Coast Range and Willamette Valley of western Oregon. The breakouts
generally indicate a NNW to NNE orientation of maximum horizontal compression
(oH[subscript max])...

Channel evolution and influences of changing floodplain
characteristics, heterogenous bank materials, and altered flow regimes were
examined along the Willamette River, a large alluvial river in northwestern
Oregon. The Willamette River is composed of a series of geomorphically
diverse reaches, which have each evolved uniquely in the century following

How does transboundary water cooperation begin at the initial stages? Countries in many transboundary basins either do not cooperate at all or have ceased cooperation altogether. Yet cooperation does often prevail, resulting in 688 water-related treaties signed between 1820 and 2007. The question we address here is, by which practices...
After the April 2010 explosion on the Deepwater Horizon oil rig, and subsequent release of millions of barrels of oil, two Corexit oil dispersant formulations were used in unprecedented quantities both on the surface and sub-surface of the Gulf of Mexico. Although the dispersant formulations contain four classes of surfactants,...

The objectives of this study were: 1) to identify and map the
experimental area of Meadow Creek watershed by existing vegetation,
and 2) to identify and map the experimental area of Meadow Creek
watershed by habitat types. The classification system adopted for
this study was based on the habitat type...
Surface and subsurface mapping are combined to determine the
geologic history along the San Gabriel fault near the town of Castaic.
Palomas Gneiss, Whitaker Granodiorite, and Pelona Schist are basement
terranes encountered in the subsurface. West of the San
Gabriel fault, basement is unconformably overlain by marine middle
to late...
BACKGROUND: Circadian clocks provide an adaptive advantage through anticipation of daily and seasonal environmental
changes. In plants, the central clock oscillator is regulated by several interlocking feedback loops. It was shown that a
substantial proportion of the Arabidopsis genome cycles with phases of peak expression covering the entire day.
Synchronized...
