Jp. Chen et al., NONLINEAR DYNAMICS IN THE ULTRADIAN RHYTHM OF DESMODIUM-MOTORIUM, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 50(12), 1995, pp. 1113-1116
The dynamics of the lateral leaflet movement of Desmodium motorium is
studied. Simple periodic, quasiperiodic and aperiodic time series are
observed. The long-scale dynamics may either be uniform or composed of
several prototypic oscillations (one of them reminiscent of homoclini
c chaos). Diffusively coupled nonlinear oscillators may account for th
e variety of ultradian rhythms.
