Regenerated extracellular NH4+ affects the motile chemosensory responses of batch-cultured Oxyrrhis marina

摘要

Regenerated extracellular NH4⁺in laboratory batch cultures of the heterotrophic marine microzooplankter Oxyrrhis marina affects the strength and consistency of chemotaxes elicited by synthetic and biogenic chemoattractants. The ecological relevance of experiments with batch-cultured O. marina and limitations of the microcapillary assay for the study of chemosensory behaviours are discussed.
