  1. Lunar Cyclefor Amphibian Reproductive Phenology Rachel A. Grant, Elizabeth A. Chadwick , Tim Halliday. 2009.Lunar cycle: a cue for amphibian reproductive phenology?Animal Behaviour 78 , 349–357. 吳佩真 698430582

  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. Grant, Elizabeth A. Chadwick , Tim Halliday. 2009.Lunar cycle: a cue for amphibian reproductive phenology?Animal Behaviour 78 , 349–357.

  4.
