More than meets the nose rapid adaptation to social complexity in laboratory-reared wild mice may be mediated by epigenetic inheritance
Meeting Abstract 38.5 Wednesday, Jan. 5 More than meets the nose: rapid adaptation to social complexity in laboratory-reared wild mice may be mediated by epigenetic inheritance. NELSON, A.C.*; POTTS, W.K.; University of Utah; University of Utah adam.nelson@utah.edu Mice in large populations have a complex social structure and large variance in mating success; as a result, social and […]

Flexible sex allocation in a group-living simultaneous hermaphrodite
Meeting Abstract 38.5 Thursday, Jan. 5 Flexible sex allocation in a group-living simultaneous hermaphrodite HART, Mary K; Univ. of Kentucky, Lexington mkhart0@yahoo.com Phenotypic plasticity can be helpful for maximizing mating success in variable environments and thus may generate different sex allocation patterns among populations. For Serranus tortugarum, a simultaneously hermaphroditic fish, proportional male allocation (testis mass/total gonad […]
