The focus of the proposed research group is to study the link between genotype and phenotype of evolutionary adaptive traits, a vital question of evolutionary biology in the postgenomic era. The group will study the morphological and genomic basis of a unique reproduction strategy in Sulawesi ricefishes (Actinopterygii: Adrianichthyidae) called “pelvic brooding”. In pelvic brooding species, females carry the eggs in an abdominal concavity until they hatch, which is assumed to be an adaptation to a predominantly pelagic lifestyle.
