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

Martel, Claire M.

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.
