of his goals. A definition of demagoguery is provided and is
applied in an analysis of...
from the summer dry season to the winter wet season. Such movement that connects summer and winter habitats may be particularly important for coho salmon, O. kisutch, because availability of overwintering habitat can limit freshwater survival for this species. Here, I describe basin-scale variability in the spatial pattern of fall...
An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in
chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20
minutes) and expelled into the plasma to become bound to proteins. In
contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...
