... the use of dietary antioxidants, including carotenoids. As carotenoids are closely associated with the expression of secondary sexual signals, the allocation of carotenoids to sexual signal versus antioxidant defences may vary with age. In this study, we explored how carotenoid-based ornament...

... signal mate quality and are not a species-specific characteristic. We discuss the use of principal component analysis in analysing spectral data in the context of visual communication. We propose the alternative application of confidence intervals of averaged spectra as a novel straightforward...

...) and 300–400 Hz ( P =0.065). We recorded peak waggle phase vibrations from 206 to 292 Hz (244±28 Hz; mean ± S.D., N =11). The maximum measured signal − noise level was +12.4 dB during the waggle phase (mean μ5.8±2.7 dB). The maximum vibrational velocity, calculated from a filtered signal, was 128 µm s −1...
