The distribution and abundance of the interstitial acoel turbellarian,
Diatomovora amoena Kozloff, 1965 was studied in an
estuarine intertidal sand flat in Yaquina Bay, Oregon, from May
1970 through May 1971.
Monthly measurements of biological (organics, sulfides, chlorophyll,
and carotenoids), pore water (salinity, pH,oxygen, and temperature),
and sediment (fine sediment...
A two-year field study was made of a population of the California
Sea Mussel, Mytilus californianus, located on a protected tidal bench
at Yaquina Head on the Central Oregon Coast. This animal was
chosen because it is attached to the rocks, filters particulate matter
from the water, produces large amounts...
This investigation examined the community structure of two intertidal sedimentary environments on the Oregon coast in terms of species composition and vertical distribution.
A coring device was used to obtain samples from two levels above MLLW in each beach on four occasions. Of the 54 taxa found, 46.2% were crustaceans,...
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...
