Lunar Cycle and Amphibian Reproductive Phenology Relationship

This study explores the correlation between the lunar cycle and amphibian reproductive behaviors, including arrival, amplexus, spawning events, and newt sightings. The findings suggest that breeding phenology in amphibians reflects the periodicity in the lunar cycle, with different species showing varying responses. Factors such as moonlight, gravitational peaks, geomagnetism, weather, and artificial light influence amphibian behaviors.

  2. Breeding phenology in amphibians reflects periodicity in the lunar cycle. • Unimodally - largely around the full moon with very few around the new moon - large arrival, amplexus and spawning events in anurans • Bimodally - first sighting and peakarrival events of Lissotriton and Triturus newts.

  3. ← Large spawning: frequency of occurrence in each moon phase for B. bufo and R. temporaria at Marston Pond. → First sighting: frequency of occurrence in each moon phase for L. vulgaris,L. helveticus and T. cristatus in Sussex, U.K. Rachel A.
