A 5-year time series of coastal zone color scanner imagery (1980-1983, 1986) is used to examine
changes in the large-scale pattern of chlorophyll pigment concentration coincident with the spring
transition in winds and currents along the west coast of North America. The data show strong
interannual variability in the timing...
During the years between 1930 and 1950 a number of attempts
were made to introduce techniques and ideas from cytology,
ecology, and genetics into the field of taxonomy. Advocates of
this "experimental taxonomy" believed that cytological, ecological,
and genetic techniques would provide a rigorous, objective

A study was conducted to compare snow accumulation and melt during rainfall in adjacent forest and clearcut plots in the
transient snow zone of the western Cascade Range in Oregon. Snow accumulation differences were determined by comparing the water equivalents of forest and clearcut snowpacks. During rain-on-snow periods, energy balances...
