Zooplankton samples taken during daylight periods in a fast flushing estuary on the Central Oregon coast were analyzed for Brachyuran and Anomuran larvae and also for benthic gammaridean amphipods and Myscidacea. Several larval stages of Pinnixa littoralis, Hemigrapsus oregonensis, Pachycheles spp., Cancer oregonensis and Pagurus granosimanus were sufficiently abundant for...
During the Callianassa californiensis larval release period, weekly zooplankton samples were taken through daylight tidal cycles near the mouth of a small, fast flushing estuary on the Central Oregon coast. Although C. californiensis adults are confined to estuaries and embayments, stage I zoeal larvae were shown to be exported from...
The microdistribution of the amphipod Eohaustorius brevicuspis was
examined over a 19 month period. Field sampling was conducted principally
at Lost Creek State Park, Oregon, and on one occasion at Driftwood State
Park, Oregon. Both are high-energy, fine sand beaches which appear to be
uniform. Stratified random samples were taken...
