Meeting Abstract 146.5  Monday, Jan. 7  Rapid neurosteroidal regulation of paternal care PRADHAN, DS*; SOLOMON-LANE, TK; WILLIS, MC; GROBER, MS; Georgia State Univ.; Georgia State Univ.; Georgia State Univ.; Georgia State Univ. dpradhan1@student.gsu.edu In vertebrates, shifts in profiles of circulating steroid hormones are critical for reproductive success because they regulate fundamental aspects of reproductive life-history/phenotype. Analyses of […]

Meeting Abstract 146.6  Monday, Jan. 7  Epigenetic regulation of myogenesis in a growth paradigm-specific manner. BIGA, PR*; FROEHLICH, JM; University of Alabama at Birmingham ; University of Alabama at Birmingham pegbiga@uab.edu Piscine growth is unique in that many species exhibit patterns of muscle growth opposite that of mammalian species. Many teleosts exhibit hyperplastic muscle growth throughout their […]

Meeting Abstract 146.2  Monday, Jan. 7  Different neural target tissues mediate melatonin-dependent regulation of the RFamides, kisspeptin and gonadotrophin-inhibitory hormone, in Siberian hamsters HENSON, J.R.*; FREEMAN, D.A.; Univ. of Memphis; Univ. of Memphis jrhenson@memphis.edu Siberian hamsters exhibit seasonal rhythms in physiology and behavior that aid in their ability to cope with annual changes in the environment. These […]
