The effects of artificial shading and aspect on the performance of 1-0 container-grown Douglas-fir seedlings were evaluated 1 year after outplanting on four different aspects in southwest Oregon. The test areas, all characterized by steep slopes and shallow, skeletal soils with a surface mantle of loose rock and logging slash,...
It has been suggested that production in offshore waters of the subarctic Pacific is limited by availability of dissolved Fe. Although that is not yet adequately established, the functional consequences of the limitation (if it exists) can be characterized from the results of the Subarctic Pacific Ecosystem Research (SUPER) program....
Fungi from the genus Chlorociboria are known for their production of the blue-green quinonic pigment xylindein. Extracted xylindein has been the subject of investigations ranging from fabric dying to use a coloring agent in paint, and shows potential as an organic semiconductor in organic photovoltaics (OPVs) and other technologies. However,...
Early adulthood is a time of transition when large segments of the population embrace new roles and show decreases in behaviors and problems thought to underlie suicide risk. Still, other segments show emergent or worsening psychopathology per-haps exacerbated by age-related disconnection from prior relational and institutional supports. Suicide prevention efforts...
A mooring system was designed and constructed to make possible
the installation and the recovery of racks of sample panels for
a study of deep-ocean wood-boring molluscs. Racks containing
pine, fir, oak, and cedar boards were exposed to borer attack at
six stations with depths of 50, 100, 150, 200,...
