Lunar Reproductive Timing Acts as a Magic Trait and May Recruit Additional Isolating Barriers in Sympatric Marine Midge Populations

Alexander Jacobsen, Runa K. Ekrem, Tobias S. Kaiser

The paper shows lunar reproductive timing in marine midges acts as a magic trait, driving reproductive isolation and recruiting additional barriers in sympatric populations.

How competition can drive allochronic divergence: a case study in the marine midge, Clunio marinus

Alexander G.G. Jacobsen, Tobias S. Kaiser, Chaitanya S. Gokhale

The paper uses an individual-based model to show that competition-induced density-dependent fitness can drive sympatric allochronic divergence in Clunio marinus populations.
