Selected zooplankton from three oligotrophic lakes in Oregon were studied to determine whether or not their instantaneous birth rates and densities could be used in lake classification. The species of zooplankton studied in their respective lakes were Daphnia, pulex in Crater Lake, Daphnia longispina in Odell Lake, and Daphnia longispina...
This technical report summarizes the
results of a three year study of the zooplankton
living in the nearshore zone off
Newport, Oregon. The sampling program was
part of the Early Life History (ELH) project
of the Oregon State University Sea Grant Program
and was designed to study the ecology
of...
In an effort to elucidate the mechanism responsible for large-scale
zooplankton variability in the California Current, zooplankton biomass and
hydrographic data from the California Cooperative Fisheries Investigation
data set and wind data from Fleet Numerical Oceanography Center model
analyses have been used to construct a box model biomass budget. The...
A study has been made of the vertical distributions and
migrations of a large number of zooplankton species at Weather
Station "P" in the Subarctic Pacific. Simultaneously towed horizontal
opening-closing nets were used for the study. The distributions
and migrations of 104 taxa have been subjectively grouped
into seven basic...
During the summers of 1967 and 1968 the horizontal distribution and did vertical migrations of zooplankton were studied within the unique environment of Crater Lake. Sampling of the horizontal
distribution was done by towing plankton nets vertically in different locations. The vertical distribution was sampled by towing at different depths...
