The Forest Service and the Bureau of Land Management propose to adopt coordinated ecosystem management direction for the lands they administer within the range of the northern spotted owl. This Supplemental Environmental Impact Statement (SETS) presents as alternatives the options, with slight modifications, developed by the Forest Ecosystem Management Assessment...
Regulation of expression of three genes in the polyhedron
envelope protein (PEP) gene region of the Orgyia pseudotsugata
multinucleocapsid nuclear polyhedrosis virus (OpMNPV) was
examined. These genes include open reading frame (ORF) 1 (encoding
p21), ORF 2 (encoding gp16), and ORF 3 (encoding the polyhedron
envelope protein). The effect of...
Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato
spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint,
initially observed in a research greenhouse (Corvallis, OR), included stunting and
downward curling of leaves accompanied by bronzing, and occasionally tip necrosis.
Young leaves appeared either symptomless, deformed, or...
The ecology of netleaf hackberry (Celtis reticulata Torr.) is poorly known
throughout its broad western range. To gain some understanding of the species' basic
ecology, three components of its life history were studied. First, seed germination
requirements were analyzed under laboratory conditions. Second, hackberry population
dynamics were evaluated from tree...
