Measurements on growth traits up to 41 years of age
from 68 progeny sites in eight first-generation breeding
zones of coastal Douglas-fir (Pseudotsuga menziesii
[MIRB.] FRANCO var. menziesii) in the US Pacific Northwest
were used to investigate age trends of genetic parameters
and to determine optimum age of selection. Heritabilities...
In shallow water, any two waves of the same frequency are shown to produce complex patterns of
drift velocity above the sea bed. If the longshore components λ₁, λ₂ of the wave numbers of the two
waves are different, these steady flow patterns exhibit a longshore periodicity of wave number...
The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...
The aims of this study were first, to test the hypothesis that metrics of fish growth and condition relate positively to parasite species richness (S[subscript R]) in a salmonid host; second, to identify whether S[subscript R] differs as a function of host origin; third, to identify whether acquisition of parasites...
Eukaryotic ribosome biogenesis involves ~200 assembly
factors, but how these contribute to ribosome
maturation is poorly understood. Here, we
identify a network of factors on the nascent 60S subunit
that actively remodels preribosome structure. At its hub is
Rsa4, a direct substrate of the force-generating ATPase
Rea1. We show that...

A summary of one phase of a direct observational program conducted
in the coastal region off Oregon is presented. The measurements were
made primarily on the continental shelf in late coastal upwelling season
(August and September 1966). The principal measurements were time
series of horizontal current velocity and temperature fields;...
