The life cycle of Callianassa californiensis Dana, 1854, was studied in the tidal estuary, Yaquina Bay, Oregon. At this latitude it is largely restricted to intertidal sandy mudflats under predominately marine influence. Salinity and temperature appear to determine its distribution to a greater extent than does sediment type. Vertical movement within the sediment is related to the tides on a day to day basis and to temperature on a seasonal basis. Large-scale breeding generally begins in the spring, and ovigerous females may be plentiful in the cooler layers of mud until August. It is not clear what triggers larval release, but temperature and tidal conditions seem to be important. All five zoeal stages are found in the plankton from the mouth of the bay to three miles offshore during late spring and summer. Nearshore waters appear to act as a larval reservoir along this part of the coast, and successful larval settlement may depend upon high-tide transport into a bay. / Graduation date: 1972

This is the first attempt to study the circumglobal pelagic planktonts of the Family Phronimidae collected from all oceans. Before Vosseler (1901) published his work on the systematics of the phronimid species, the sexual dimorphism and the age variation in these animals proved confusing to the taxonomists. Synonyms of the species were mostly made at this period. [...]

Walking leg closer muscle neuromuscular parameters were recorded electrophysiologically from homothermally and heterothermally acclimated Carcinus maenas (eurythermic) and Cancer pagurus (stenothermic). Homothermal (and immobilised) crabs of both species were acclimated to either 8 C or 22 C, whereas heterothermally acclimated crabs were acclimated to 8 C and 22 C coincidentally, exposing the animal's central nervous system (CNS) to either the warm (22 C) or cold (8 C) acclimation temperature. Thus, heterothermal acclimation exposes the CNS/endocrine system and one set of walking legs at one acclimation temperature, the contralateral walking legs are acclimated to the other acclimation temperature. This allowed an investigation into the CNS influence on the attainment of acclimation by walking legs. Comparisons of acclimation responses of the neuromuscular function of isolated walking legs from the same animal were done with respect to the walking leg and CNS acclimation temperatures experienced. Animals were acclimated for two weeks, recordings were taken of excitatory junctional potentials (EJP) etc., from dactylopodite closer muscle fibres when stimulated by the tonic motor axon over an experimental temperature range (6-26 C).The acclimation responses in homothermally exposed crabs of both species resulted in partial (Precht, type III) responses in resting potential, single and double pulse stimulated excitatory junctional potential amplitudes, these were interpreted as responses that allowed the maintenance of muscle function in the new thermal condition. With respect to long term thermal acclimation other electrophysiological parameters gave equivocal compensatory responses. Capacity acclimation responses were more complete in C.pagurus than C.maenas. In heterothermally acclimated animals resting potentials and EJP amplitudes revealed partial acclimation responses in a compensatory manner. Acclimation of heterothermally acclimated C.maenas and C.pagurus was determined to be independent of a CNS influence, indicating thermal acclimation was in response to the local tissue acclimation temperature.

A quantitative study of the decapod crustacean community commensal with the coral Pocillopora meandrina var. nobilis Verrill was undertaken and was accomplished through an analysis of communities collected in coral heads in Kaneohe Bay, Oahu. The coral head microhabitat was described and analyzed. The community was described and its relationship to the coral head habitat defined. It was found that community composition was affected by coral head size and that relative composition of the communities changed as the coral heads increased in size. Through stomach contents analysis and trophic behavior experiments the commensals were found to utilize the coral as a source of food, primarily by feeding on material caught on the coral. A correlation between the total biomass of the crustacean community and the surface area of the coral heads in which they were collected was found, suggesting that the com- munity is limited by the amount of surface area of a coralhead This may reflect the amount of food available to the symbionts. There was no good correlation between surface area of the corals and the biomass of the individual components of the community, indicating that other factors, such as the behavioral peculiarity of pairing and interspecific competition probably determine the exact composition of the community that a coral head can support. It was concluded that the crustaceans studied were true commensals with the coral, and that the commensal association involves the host providing a source of food as well as protection for the symbionts. / Typescript.
