Project description:Throughout the animal kingdom, we know many examples of mating system evolution that exemplify adaptive responses to changes in the environment, yet our understanding of the accompanying neural and molecular mechanisms that give rise to such behavioral changes remains understudied. In the present study we aimed to define the molecular basis of interspecific variation in social organization in Ectodini cichlids from Lake Tanganyika. We selected four closely related species that represent two independent evolutions of monogamy: the polygynous Xenotilapia ochrogenys, the monogamous Xenotilapia flavipinnis, the polygynous Microdontochromis tenuidentata and the monogamous Asprotilapia leptura. Using a single cichlid microarray platform, we conducted a total of 28 direct comparisons for neural gene expression level among males and 26 among females of four species that represent 2 independent evolutions of monogamy. Our results indicate the gene expression profiles display remarkable plasticity across different time scales because we find differences associated with sex, mating system, and lineage.
