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 bay.
Environmental factors considered were salinity, temperature,
and sediment composition.
The results of this study do not single out a factor as the one
limiting the distribution of N. caecoides in Yaquina Bay. During
summer months, it is possible that sediment porosity, organic
content and temperature operate together to form an unfavorable
environment. / Graduation date: 1966
