title: Conditioned water affects pair formation behaviour in the marine polychaete Neanthes (Nereis) acuminata.
abstract: Assessing cues from conspecifics is paramount during mate choice decisions. Neanthes acuminata is a marine polychaete with a unique life cycle: pair formation, female death following reproduction, male parental care and male ability to mate again after egg care. Males completing such egg care are 'experienced'. Females have been shown to prefer experienced males over all others, including aggressively dominant males. As the female dies following reproduction, the reproductive success of her offspring depends upon successful parental care by the male. It is therefore vital that the female makes a good mate choice decision. This paper shows that the use of conditioned water from males caring for eggs and newly experienced males caused the female to alter her choice to a previously undesired male. However, conditioned water from males, which had reproduced but were isolated for 2 weeks, did not have the same effect on pairing behaviour. This indicates that the smell of experience is short lived.
