Abstract: In the theory of social selection, the fitness of an organism is determined by the phenotype of its social partners as well as its own phenotype. A quantitative genetic model of selection has been proposed in which social selection is contingent on 1) the phenotype of a focal individual covarying with a trait of its social partner and 2) the fitness of the focal individual is influenced by the phenotype of its social partner. This study will focus on the possibility that socio-temporal niche construction – organisms altering their temporal behavior to modify their social environment - can be a mechanism for altering selective advantage. The social and temporal behavior of the forked fungus beetle ( Bolitotherus cornutus ) will be observed to empirically test the hypothesis that covariance can be generated by the variability in temporal behavior and thus provide the opportunity for social selection.
