How competition can drive allochronic divergence: a case study in the marine midge, Clunio marinus Synchronizing mating to extrinsic environmental cycles can increase the chance of successful reproduction. However, the resulting temporally-assorted mating may precipitate speciation if coupled with ...

How can larval #competition for space, adult #reproductive #timing and the #tides interact to produce different timing strains, aka #chronotypes, of the marine insect #Clunio?

Curious how the #moon is perceived, controls #development, and may drive #speciation in a #marine #insect?

… and then time these hours to the lowest low tides. These tides always occur at full and new #moon. Clunio has an internal timer, a so-called #circalunar #clock. It enables the midges to predict #moon phases and allows adults to only emerge at the right #time.
