The feeding habits of the Dover sole and rex sole (mainly juveniles) and of slender sole and Pacific sanddab were investigated at seven stations on the continental shelf off central Oregon. Dover sole had a catholic diet, feeding on a large variety of infaunal and epifaunal invertebrates. The composition of...
The construction of the first genetic map in autotetraploid blueberry has been made possible by the development of new SNP markers developed using genotyping by sequencing in a mapping population created from a cross between two key highbush blueberry cultivars, Draper × Jewel (Vaccinium corymbosum). The novel SNP markers were...
The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...
We examine large-scale atmospheric behavior around the time of the spring and fall transitions in the coastal ocean off the west coast of North America. Records of adjusted sea level (ASL), coastal wind stress, sea level atmospheric pressure (SLP), and 500-mbar heights for the years 1971-1975 and 1980-1983 are analyzed....
Estimates of heat flux from direct measurements of vertical velocity-temperature
fluctuation correlations have been obtained from vertical profiles
through turbulent patches in the main thermocline. These have been compared
to more indirect flux estimates derived from dissipation rates of turbulent kinetic
energy and temperature variance. Because record lengths are limited...
An abundant fruiting of a black morel was encountered in temperate northwestern New South Wales (NSW), Australia, during a mycological survey in Sep 2010. The site was west of the Great Dividing Range in a young, dry sclerophyll forest dominated by Eucalyptus and Callitris north of Coonabarabran in an area...
What value does federal designation add to open space resources that are not all federally owned and managed? Over the years the federal government, under the auspices of the National Park Service and USDA Forest Service, has designated trails across the United States as National Recreation Trails. A survey of...
The initial composition of a river plume depends on the cumulative turbulent
entrainment within the estuary and how this dilutes the supplied freshwater. Here we
examine the relative roles of turbulence and freshwater input using observations from the
Columbia River estuary and plume during two periods with contrasting river flow....
Turbulence controls the composition of river plumes through mixing and alters the plume's trajectory by diffusing its momentum. While believed to play a crucial role in decelerating river-source waters, the turbulence stress in a near-field river plume has not previously been observationally quantified. In this study, finely resolved density, velocity,...
An experimental investigation of a two·dimensional turbulent jet in a quiescent environment has been
carried out to determine the structural characteristics of the outer, intermittent turbulent motion. An
overall picture of this motion was deduced from the results which indicate that, on the average, the
turbulent bulges are of the...
