 M. C. P. Amorim, P. J. Fonseca, V. C. Almada (2003): Sound production during
 courtship and spawning of Oreochromis mossambicus: male-female and male-male
 interactions. Journal of Fish Biology; Volume 62, Issue 3, Page 658 
 Abstract: The role of sound production of the Mozambique tilapia Oreochromis
 mossambicus in agonistic and mating interactions observed during hierarchy
 formation and in established groups was examined. Only territorial males
 produced sounds, during male-female and male-male courtship interactions and
 during pit-related activities (e.g. dig, hover and still in the nest). Sound
 production rate was positively correlated with courting rate. Although
 sounds in other cichlids are typically emitted in early stages of courtship,
 O. mossambicus produced sounds in all phases, but especially during late
 stages of courtship, including spawning. It is suggested that the acoustic
 emissions in this species may play a role in advertising the presence and
 spawning readiness of males and in synchronizing gamete release.

Subject: PhD opportunity : Queensland fruit fly acoustic signals

<address>Title: <strong>PhD opportunity : Queensland fruit fly acoustic
 <div><font face="Arial" color="#000000"><br></font></div>
 <div><font face="Arial" color="#000000">The<i> Animal Behaviour
 Research Group</i> at Macquarie University, Sydney, Australia has an
 opening for a PhD student to investigate acoustic calling and
 courtship signals in Queensland fruit flies (Tephritidae), under the
 primary supervision of Dr Phil Taylor. Projects might entail, for
 example, general analysis of signals, correlation of acoustic signals
 with sexual success and other male traits (eg size, symmetry,
 nutrition, age), and playback trials. Grant support is available to
 cover all equipment and travel expenses entailed in this research.
 Candidates with an interest and experience in bioacoustics are
 especially encouraged to apply.</font></div>
