Table_2_In situ testing of candidate odorant cues in coral-reef fish: a new method with tests of dimethylsulfoniopropionate and betaines.docx

In situ testing of candidate odorant cues directly in coral-reef communities has the advantage that, in principle, it permits the behavioral responses of all fish species to be evaluated in the species’ natural environments. The success of in situ testing depends critically, however, on a suitable method of odorant release. We provide here a proof-of-concept for a new method of release that (instead of using distilled water as an ejection medium) ejects odorant-containing local reef water remotely and silently over an extended time period using gravity as the motive force. The ejected water, b... Mehr ...
