Absorption of iron from foods has been reported to be inhibited by
various factors including some diet components. Fiber from different
sources has been observed to bind ferrous iron. This may be the reason
for iron deficiencies observed in populations that consume diets high in
non-digestible materials.
The effect of...
Jellyfish benefit from many of the changes mankind is making to the ocean. Climate change, overfishing, nutrient runoff, the introduction of invasive species, and coastal development all promote these ancient, gelatinous creatures. Because of their familiarity to readers and affinity for degraded places in the ocean, jellyfish are used to...

Communities must adapt...
As species of ash trees become increasingly threatened worldwide by exotic pests and pathogens, it is important to develop descriptions of their ecologies that help guide the conservation and restoration of forests in which they are a major component. Oregon ash (Fraxinus latifolia) is a dominant tree species in wetland...
Bioavailability (BA) of vitamin B6 (B-6) from foods may be
limited. The knowledge of the BA of B6 from food is important in
that this would help to understand if the B6 present in the diet of
individuals will meet the requirements for this vitamin.
The purpose of this study...
The spatial organization of farm units in Polk and Linn counties
in the mid-Willamette Valley has undergone significant change over
the past 30 years. Whereas most study areas operations in the
1930's and 1940's consisted of small family owned farms with contiguous
land bases, present mid-Willamette Valley units vary considerably...

The cluster preserves 18 cones but probably bore at least 24 pollen cones...
Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...
A necrosis at the tip of cones was observed on hop (Humulus lupulus), cultivar "Nugget", grown in Oregon in the early 1990's. Fusarium sambucinum and F. avenaceum were recovered from symptomatic cones in 1998 and preliminary inoculation experiments suggested both Fusarium species could cause hop cone necrosis. Studies were carried...
