Individuals of the shore crab Carcinus maenas were exposed to artificial cycles, applied in tidal antiphase, of pairs of the three major environmental variables that entrain circatidal rhythmicity in this species: salinity, temperature, and hydrostatic pressure. During entrainment, the observed locomotor activity patterns were dominated by exogenous responses to high pressure, low temperature, or low salinity. In subsequent constant conditions, many of the crabs showed bimodal circatidal rhythms, with peaks phased to the times of expected high-tide characteristics of high pressure, low temperature, or high salinity. Similar bimodal rhythms were induced by exposing freshly captured crabs, with free-running circatidal rhythms, to tidal antiphase cycles of each of the three environmental variables applied individually. The hypothesis that circatidal rhythmicity in this species is controlled by at least two separate circatidal oscillators, with differential sensitivities to specific cyclical environmental variables, is discussed.
