Knowledge of regional-scale patterns of plant community structure and controlling factors is largely qualitative and based on numerous local studies. Data from a subsample of 10,000 field plots were used to quantify and map compositional gradients of woody plant communities across Oregon forests. Canonical correspondence analyses explained 9-14% of the...
Calanoid copepod diet was investigated in Oregon coastal waters to determine
the trophic significance of phagotrophic protists as copepod prey within an ecosystem
where the microplankton biomass is typically dominated by large diatoms. Prior to and
during the 1991 upwelling season, clearance rates on phytoplankton and phagotrophic
ciliates were measured...
