The ecology and evolution of reproduction in the tessellated darter
We have also been conducting research on a new study species. In the tessellated darter, Etheostoma olmstedi, male alternative reproductive behaviors exist: Some males desert their offspring while other ‘allopaternal’ males care for these unrelated young. Our research on this species is focused on understanding the evolution of allopaternal care, the role of competition for resources on male behavior and its affect on sexual selection and female choice. In this species, female prefer large males but also prefer nests with healthy eggs.
