An alarm response in the northern abalone, Haliotis kamtschatkana. Cook, K. A. Master's thesis, University of Alberta (Canada), Canada, 1992.
Paper abstract bibtex The northern abalone, Haliotis kamtschatkana exhibited an alarm response to the scent of damaged conspecific tissue and to mucus activity released by handled conspecifics under laboratory and field conditions. The alarm response was characterized by agitated running behaviour. This response may serve to reduce predator efficiency. Exposure to homogenized conspecific tissue extracts revealed that the source of the alarm stimulus was associated with the mucus producing hypobranchial gland. The alarm substance is probably multifunctional and serves as more than just as a conspecific warning device. H. kamtschatkana has probably evolved the ability to detect a metabolite associated with the hypobranchial gland that may serve other functions in the living animal. Spawning resulted in reduced responsiveness under laboratory conditions on two separate occasions with different animals. Exposure to damaged tissue from taxonomically related and distant species with which H. kamtschatkana co-occur and do not co-occur provided evidence to suggest that H. kamtschatkana may also have evolved a response to heterospecific stimuli that may serve to reduce predator efficiency. These responses may be due to either ecological or taxonomic relationships or both. (Abstract shortened by UMI.)
