Laboratory studies were conducted under different temperature and moisture regimes to evaluate the effects of temperature and moisture on stand establishment and seedling characteristics associated with stand establishment. Percent stand and days to 25% emergence were used as indexes of stand establishment. Seedling characteristics analyzed were: shoot length, coleoptile length,...
The distribution patterns of quartz and opal contents and the distribution
patterns of radiolarian assemblages, in the sediments of the
southeastern Pacific, are largely controlled by both the surface winds
and the mixed-layer oceanic circulation. The distribution pattern of
quartz is related to eolian and ice-rafted transport, as well as...
