Unexploited females and unreliable signals of male quality in a Malawi cichlid bower polymorphism

Unexploited females and unreliable signals of male quality in a Malawi cichlid bower polymorphism

Complex signals present 2 outstanding questions: why do they exist and how are they interpreted? Multiple signals can be beneficial for the increased diversity or redundancy of information they convey; however, it is not clear how receivers use this additional information. I investigated a lekking Malawi cichlid fish that builds polymorphic bowers; some males build their sand spawning craters o...

A role for male bower size as an intrasexual signal in a Lake Malawi cichlid fish

Disruptive sexual selection through female mate choice has been proposed as a key mechanism driving the evolution of haplochromine cichlid fish diversity. Here we investigated if male secondary sexual traits employed by females in direct mate choice have an additional function in male competition. We conducted a field experiment on aggression among males of a lekking Lake Malawi cichlid species...
