    Notes: Abstract Temporal analyses were applied to the tone pulses within the courtship songs of Drosophila melanogaster, D. simulans,their interspecific hybrid, and behavioral mutants of D. melanogaster.Linear regression was performed on various parameters of the song pulses (cycles per pulse, absolute peak amplitude, intrapulse frequency, number of peaks in fast Fourier transform, width of the primary frequency peak, and interpulse interval), as a function of their positions within pulse trains. Significant differences in the slope values of these two species and of the mutant genotypes allowed for discriminative quantification of temporal changes within trains. These results are discussed in relation to previous kinds of temporal analyses of Drosophilacourtship songs and also with regard to the mechanisms of song production.

    Spectral analysis of courtship songs in behavioral mutants ofDrosophila melanogaster (1989)
    Springer
    Behavior genetics 19 (1989), S. 503-528 
    Details
    ISSN: 1573-3297
    Keywords: cacophony mutant ; dissonance mutant ; fruitless mutant ; period mutants ; pulse song ; sine song ; fast Fourier analysis ; acoustic spectra
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Psychology
    Notes: Abstract Spectral analyses were applied to the courtship songs of the mutantscacophony (cac), dissonance (diss), fruitless (fru), andperiod (per), as well as to the double mutantcac diss. Aberrant intervals between song pulses were observed indiss, cac, cac diss, andfru songs,diss males displayed a defect in song hums manifested by an irregular sine wave, although the fundamental frequencies were normal. Sine song frequencies and intrapulse frequencies were aberrant incac diss males. Two per mutant alleles (per o1 andper s) were associated with normal seng pulses and hums. These findings are discussed with regard to the mechanisms of song production and the role of these sounds inDrosophila reproduction.
