Ciliate zooplankton

In the initial mixed zooplankton experiments, Long et al. (submitted) found that crustacean mesozooplankton, dominated by adult copepods A. tonsa and P. pelagicus, significantly suppressed colony formation. In other experiments, Long et al. (submitted) found that infochemical cues alone from the mesozooplankton A. tonsa alone suppressed colony formation. Long et al. (submitted) also observed that the colony suppression effect of A. tonsa was density dependent. In experiments with the microzooplankton Euplotes spp., Long et al. (submitted) reported that info-chemical cues from this ciliate enhanced P. globosa colony formation.
