The effects of nitric oxide (NO) on the individual components of Azotobacter vinelandii
nitrogenase have been examined by kinetic and spectroscopic methods. Incubation of the Fe protein (Av2)
for 1 h with stoichiometries of 4- and 8-fold molar excesses of NO to Av2 dimer resulted in a complete
loss of...
RNA sequencing (RNA-seq) and genotyping-by-sequencing (GBS) were used for single nucleotide polymorphism (SNP) identification from two economically important obligate plant pathogens, Pseudoperonospora cubensis and P. humuli. Twenty isolates of P. cubensis and 19 isolates of P. humuli were genotyped using RNA-seq and GBS. Principle components analysis (PCA) of each data...
Air-breathing marine animals face a complex set of physical challenges associated with diving that affect the decisions of how to optimize feeding. Baleen whales (Mysticeti) have evolved bulk-filter feeding mechanisms to efficiently feed on dense prey patches. Baleen whales are central place foragers where oxygen at the surface represents the...
1. There is no evidence of a decline in the striped bass population of Coos Bay.
2. The striped bass, a species introduced to the West Coast of North America, has been important as a recreational and commercial fish in Coos Bay since the late 1920s. The catch has ranged...

Butterfly bush is difficult to control. If the infestation is only a few small plants, pulling and digging are effective. For larger plants, chemical control may be needed. If butterfly bushes are in riparian areas or near water, consult your local OSU Extension Service office, ODF Stewardship forester, or county...
Lint Slough is a small “finger” of the Alsea River estuary located in Waldport, Oregon, which drains a 4.5 square mile basin. Infrastructure associated with a former fish research facility has recently been removed and the slough is being transformed back to its natural condition.
In 1963 the Oregon Game...

cramped, viewers get confused about which figures to read first, and which legend goes with which figure
Curly dock (Rumex crispus L.) is a perennial. It does
not have creeping roots or rhizomes (Figure 1). Leaves
are oblong to nearly lanceshaped, often 12 inches or more
long, with wavy (crisped) margins (Figure 2). Erect, generally
unbranched stems up to 5 feet tall are produced in spring
and...
