Semi-Lunar Variations of Endogenous Circa-Tidal Rhythms of Activity and Respiration In the lsopod Eurydice pulchra
Open accessAbstract
When collected from the shore and placed into infra-red beam actographs in constant darkness at 15 'C in the laboratory, individual adult Eurydice pulchra Leach exhibit an endogenous circa-tidal rhythm of spontaneous swimming activity.Periodogram analysis of activity traces indicates a semi-lunar modulation in the rhythm's expression.It is most strongly expressed in isopods collected during spring tide periods.Groups of E. pulchra in moist sterilized sand were maintained in Gilson respirometers under constant darkness at 15 "C; subsequent recordings of their respiratory rate demonstrated an endogenous circa-tidal rhythm of oxygen uptake, with peak rates at the time of expected high water This rhythm was expressed during spring tide, but not neap tide periods.Relationships of circa-tidal rhythms, their semi-lunar modulations and the semilunar emergence pattern of E. pulchra are discussed.

The period of these oscillations was consistent with swimming activity and respiratory rate tidal cycles, which peak around high tides.

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.
