In addition to the nonzero effect of k 3r, inter-subject variation of k 2r from the fixed value (k 2 = 0.178/min) may also produce individually different k 3 bias in 3P++ analysis, resulting in lower inter-subject k 3 correlation between 3P + and 3P++ analyses.
Each locality has its own theme of trill calls that is distinct from those of neighboring communities, and resident males produce individually distinct trill calls within that theme.
Therefore although a tryptophan molecule may be expensive to produce individually, its low relative usage makes it cheaper to maintain overall at the cellular level.
Acoustic analysis of pup vocalisations has shown that they produce individually stereotyped vocalisations, and that this vocal signature involves the fundamental frequency, the energy spectrum, and both the frequency and amplitude modulations of the calls [39].
The construct was further subcloned to produce individually the two lobes (residues 1−88 and 89−158) of F2 TnC into the pEDTDuet-1 vector using BamHI and PstI sites.
Acoustic analysis has shown that males produce individually distinguishable calls, but it has not yet been demonstrated with playback experiments whether individuals recognize the calls of other individuals (Delgado 2007).
