Oregon State University researchers conducted a survey in 1994 of non-industrial private forest (NIPF) landowners in western Oregon and western Washington. Private forests provide valuable ecological services, such as fish and wildlife habitat, and are also partially filling the gap created by recent reductions in federal timber harvest in the...
Capillary pressure-saturation data obtained for unconsolidated porous media with different liquids are examined to investigate the effects of clay-liquid interactions on liquid retention. Liquid retention functions are assumed to reflect the effective pore-size distributions. The hydraulic variables, capillary pressure and saturation, are transformed to account for changes in liquid retention...
Eighty-one microbial species isolated from seafoods and other marine sources were examined to determine the extent of interactions among these species. Spot-plates, cross-plates, and concurrent growth experiments at 7, 15, 20, and 30 C indicated that Lactobacillus species were capable of inhibiting other microorganisms. Lactobacillus species isolated from oysters and...
An evaluation of the efficacy of steam treatment on reducing levels of Fusarium, Cylindrocarpon, and
Trichoderma within styroblock containers was conducted at the Plum Creek Nursery in Pablo, Montana. Although levels, of both Fusarium and Cylindrocarpon were significantly reduced by cleaning, relatively high populations of both these fungi persisted after...

As in various freshwater and coastal marine ecosystems worldwide, seasonal bottom water hypoxia is a recurring phenomenon in Lake Erie's central basin. While bottom hypoxia can strongly affect sessile benthic animals, its effects on mobile organisms such as fish are less understood. We evaluated the potential for bottom hypoxia to...
