Meeting Abstract P1.7  Jan. 4  Ecdysone signaling controls fat-body remodeling during metamorphosis in Drosophila melanogaster BOND, N; HOSHIZAKI, DK*; Univ. of Nevada Las Vegas; Univ. of Nevada Las Vegas dkhosh@clark.nscee.edu The major signal for entry into metamorphosis is a high-titer pulse of the steroid hormone 20-hydroxy-ecdysone (herein referred to as Ecdysone) which triggers the induction of growth […]

Meeting Abstract P1.119  Jan. 4  Early Learning of Behavioral Phenotypes in Red Crossbills SEWALL, K.*; HAHN, T. P.; University of California, Davis; University of California, Davis kbsewall@ucdavis.edu Behavioral phenotype can be shaped by learning. The fidelity with which animals learn the behavioral patterns of their parents can impact their fitness and drive population divergence. For behavioral traits […]

Meeting Abstract P1.10  Jan. 4  Developmental plasticity and heterochronic shifts induced by hypoxic conditions during early embryogenesis of zebrafish, Danio rerio SCHMIDT, K.U.; STARCK, J.M.*; Univ. Munich, Germany starck@uni-muenchen.de During the phylotypic stage vertebrate embryos pass through a period of morphological similarity. In zebrafish, Danio rerio, multiple correlations among characters stabilize morphology during the phylotypic stage, but […]
