While most organisms have biological clocks synchronized with the day-night cycle (circadian rhythms), marine animals in tidal areas have also developed circatidal rhythms to align with the tidal ...

Could the hidden seas of icy moons occasionally boil beneath kilometers of ice? Recent modeling suggests that, given just the right orbital and geological conditions, subsurface oceans on small outer ...

A hypothesis on the process of adaptation to the tidal environment in a freshwater snail. The circatidal rhythm is not expressed in nontidal individuals under natural conditions. In the early stage of ...
