Circadian components of semilunar and lunar timing mechanisms

Neumann, Dietrich·1989·Journal of Biological Rhythms

Abstract

The timing of semilunar as well as lunar reproductive rhythms has been analyzed in different geographic populations of the intertidal chironomid Clunio. In stocks of three populations differing in period and phase relationship with the lunar month, these long-term rhythms were synchronized in the laboratory by using artificial moonlight cycles of 30 days in otherwise 24-hr light-dark (LD) cycles (0.4 lux during 4 successive nights every 30 days in LD 12:12). In LD cycles of various periods, a strong synchronization was only possible in LD 12:12 and LD 11:11, whereas in LD 10:10 and LD 15:15 the synchronization by the 30-"day" moonlight cycle was weak or even absent. The study demonstrates a limited range of circadian periods for entrainment of the long-term rhythms. It is concluded that an LD cycle with a period near 24 hr is an essential zeitgeber condition for semilunar and lunar timing in this marine insect. Further, it is suggested that the underlying physiological timing mechanism of Clunio consists of a circadian function for the perception of the monthly moonlight zeitgeber cycles that entrain the endogenous, temperature-compensated oscillator of the circasemilunar (or circalunar) period. The long-term oscillator triggers the metamorphosis of the insect, and thereby determines the time of its eclosion and reproduction on the shorelines, in correlation with days of spring tides recurring about every 14-15 days.

  • Clunio marinus provides an example of combined circadian and circalunar timing that precisely orchestrates adult emergence.

    “The marine midge, Clunio marinus, provides an interesting example of combined circadian and circalunar timing, which precisely orchestrates its adult emergence [[40], [41], [42]].”
  • Experimental data in the midge Clunio are compatible with the coincidence model for moonlight detection.

    “Experimental data in the midge Clunio are compatible with such a model (58);”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
