| dc.description.abstract | In Bodega Harbor, California, the nemertean Paranemertes peregrina spawns in June or July. Adults in the study area were small in comparison to worms found on two Washington mud flats. Population density of active worms averaged 7.38 worms/m2, with much variation due to time of day of low tides. Approximately 28 percent of the active population ate during the low tide periods that were sampled. Prey included spionids, nephtyids, polychaetes with capillary setae, and syllids (in decreasing importance). The number of prey families in the diet of California nemerteans was higher than in the two Washington mud flat populations and preferred nereid prey was less abundant in California and comprised less of the total diet of nemerteans there. Spionids were the major prey of California nemerteans in spring and summer; nereids were the major prey in fall and winter. In food preference tests, nemerteans showed negative responses to phoronids and lumbrinerids and positive responses to Nephtys caecoides. In comparison to three Washington populations, the population in Bodega Harbor was most similar to a rocky intertidal population and much different from two mud flat populations. | |
