Insufficient Evidence of Purported Lunar Effect on Pollination in Ephedra

Insufficient Evidence of Purported Lunar Effect on Pollination in Ephedra.

It has been suggested that the timing of pollination in Ephedra foeminea coincides with the full moon in July. The implication is that the plant can detect the full moon through light or gravity and that this trait is an evolutionary adaptation that aids the navigation by pollinating insects. Here we show that there are insufficient data to make such a claim, and we predict that pollinations of...

No Evidence of Purported Lunar Effect on Hospital Admission Rates or Birth Rates

BACKGROUND Studies indicate that a fraction of nursing professionals believe in a "lunar effect"-a purported correlation between the phases of the Earth's moon and human affairs, such as birth rates, blood loss, or fertility. PURPOSE This article addresses some of the methodological errors and cognitive biases that can explain the human tendency of perceiving a lunar effect where there is non...

Pollen and Pollination in Ephedra (gnetales)

Moonlight pollination in the gymnosperm Ephedra (Gnetales).

Most gymnosperms are wind-pollinated, but some are insect-pollinated, and in Ephedra (Gnetales), both wind pollination and insect pollination occur. Little is, however, known about mechanisms and evolution of pollination syndromes in gymnosperms. Based on four seasons of field studies, we show an unexpected correlation between pollination and the phases of the moon in one of our studied species...
