人们早就知道天体力学会影响地球上的生命，但对这些影响的探索一直受到长时间尺度和复杂生物关系的阻碍。在这里，我们报告了由月球轨道倾角 18.6 y 振荡驱动的潮汐暴露的周期性波动，它可以使潮间带生物暴露在空气中的平均时间改变近 50%。近岸水温和贻贝的上限随着月球振荡而变化。这种变化挑战了基于快照测量的生态和生理概括的价值，并凸显了长期研究的价值。
Celestial mechanics has long been known to affect life on Earth, but exploration of these influences has been hampered by long temporal scales and complex biological relations. Here we report on a periodic fluctuation in tidal exposure driven by the 18.6-y oscillation of the moon's orbital inclination, which can change by almost 50% the average time that intertidal organisms are exposed to air. The temperature of nearshore water and the upper limits to mussels are shown to vary with the lunar oscillation. Such variation challenges the value of ecological and physiological generalizations based on snapshot measures, and highlights the value of long-term studies.
