In January 1970, collections of Serpula vermicularis L. were
obtained from Bray Point, Oregon, for the purpose of determining the
effect of acclimation to salinity and temperature on its rate of
respiration. The worms were removed from their tubes and acclimated to one of three salinities (28.8%₀, 31.1%₀, or 35.9%₀)...
Polychaete annelids from 48 benthic samples containing over
2000 specimens were identified. Samples were taken with either an
anchor dredge or an anchor-box dredge from a 15 station transect
(44° 39. 1'N) that ranges from 800 to 2900 meters in depth. Sediment
subsamples were collected and analyzed for organic carbon...
A study was undertaken in Yaquina Bay, Oregon during the
summer of 1964 to determine the distribution and the factors affecting
the distribution of the polychaete worm, Nephtys caecoides,
Hartman, 1938, in the estuary.
This organism has a continuous distribution from offshore to
a point approximately eight kilometers into the...
The syllid polychaete Autolytus varius reproduces in the spring
and early summer in Yaquina Bay, Oregon, The fertilized female
epitokes, or Sacconereis, carry the developing eggs and larvae in a
ventral sac until the larvae are ready to be released; incubation
lasts 14 to 18 days in the laboratory, The...
Symbiotic relationships of bacteria with higher organisms are
commonly observed in nature; however, the functional role of these
relationships is only rarely understood. This is particularly evident in
epibiotic bacterial associations in the marine environment where the bacteria
are often a diverse ensemble of microorganisms, thus complicating the
identification of...
