Mating behaviour in Lymnaea stagnalis pond snails is a maternally inherited, lateralized trait.

abstract：:In contrast to daily rhythms that are common in the presence of the geophysical light-dark cycle, organisms at polar latitudes exhibit many diel activity patterns during natural periods of continuous solar light or darkness (polar day and night, respectively), from 24 h rhythms to arrhythmicity. In Arctic Greenland (7...
