Monitoring reproductive success, prey species composition, and colony size of marine birds has been proposed as a method of assessing changes in marine systems that are otherwise difficult to sample (Cairns 1987). I measured inter-annual and intra-seasonal variability in reproductive parameters, taxonomic composition of the diet, and adult body condition...
Paleozoic dolomites, limestones, and detrital clastic rocks
were mapped in the Bellevue Peak 15 minute quadrangle in the
southern Mahogany Hills, Nevada. Sedimentary rock units in this
area represent shallow-shelf eastern assemblage deposits.
Shallow-shelf carbonates characterized deposition from at
least Ordovician through Late Devonian time, when clastics derived
from the...
Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...
The incidence and duration of breast feeding were determined
via telephone questionnaires from a sample of 95 women who delivered
healthy infants during the month of September 1982, in the greater
metropolitan area of Portland, Oregon. This sample was limited in
that the women were married, predominately white, over 25...
Liver X receptor (LXR), farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR) are adopted orphan nuclear receptors that function as lipid sensors. These receptors respond to cellular lipid levels and regulate the expression of target gene. Previously, it was demonstrated that low doses of chlordecone (CD) pretreatment disturbed exogenous...
Numerical simulation of the January and July global
climate with the OSU two-level atmospheric general circulation
model has generated time series of the global
distribution of selected climatic variables. Analyses of
these data for the kinetic energy and available potential
energy based on 31-day time mean statistics have been
made...
The Himalaya are the geologic manifestation of continental collision,
and in northern Pakistan the Main Mantle thrust (MMT) is a major suture along
which the collision occurred. A newly recognized basement uplift near
Besham village in southern Kohistan, adjacent to the MMT, is bounded on the
east and west by...
