Meeting Abstract 129.6  Tuesday, Jan. 7 14:45  Regulation of critical weight in the tobacco hornworm, Manduca sexta. HATEM, N.E.**; SUZUKI, Y.; Wellesley College; Wellesley College nhatem@wellesley.edu The regulation of the timing metamorphosis is a critical event in many organisms. In insects, a size assessment point called the critical weight marks the time at which metamorphosis is no […]

Meeting Abstract 129.3  Tuesday, Jan. 7 14:00  Fine Time-scale Observation of Development following Cryptobiosis yields a non-conventional Model for Toxicology COVI, JA; University of North Carolina at Wilmington covij@uncw.edu Embryos of some micro-crustaceans survive decades to centuries of continuous anoxia by reversibly arresting metabolic and developmental processes. While the ecological and evolutionary implications of these cryptobiotic ‘egg […]

Meeting Abstract 129.1  Tuesday, Jan. 7 13:30  Elucidating the Synthesis of Methyl Farnesoate in the Tissues of the Tadpole Shrimp, Triops longicaudatus TERUSAKI, A.T.*; TSUKIMURA, B.; California State University, Fresno; California State University, Fresno Aterusaki@gmail.com In crustaceans, methyl farnesoate (MF) acts as a juvenilizing factor, maintaining juvenile characteristics and delaying reproductive development. The synthesis of MF is […]

Meeting Abstract 128.4  Tuesday, Jan. 7 14:15  Recapitulating Heterochrony in Ascidian Development COLANTUONO, B*; IRVINE, S; University of Rhode Island bcolantuono5735@my.uri.edu Solitary ascidian life history can be thought of as separating Romer’s somatic and visceral organ systems. Embryonic and larval development are dominated by somatic systems (sensory and locomotory), while at metamorphosis the somatic systems are largely […]

Meeting Abstract 128.1  Tuesday, Jan. 7 13:30  How the pilidium larva uses the Hox genes HIEBERT, LS*; MASLAKOVA, SA; Oregon Institute of Marine Biology, Univ. of Oregon; Oregon Institute of Marine Biology, Univ. of Oregon lhiebert@uoregon.edu The pilidium larva is a novelty of a single group of nemertean worms called the Pilidiophora.

Meeting Abstract 128.6  Tuesday, Jan. 7 14:45  Foregut development in predatory caenogastropods: Common developmental trajectories despite changing life histories HOOKHAM, B.K.**; PAGE, L.R.; University of Victoria bhookham@uvic.ca Caenogastropods experienced an impressive adaptive radiation, with the evolution of new feeding strategies a prominent theme. The ancestral feeding condition is herbivorous grazing, whereas the derived condition is predatory feeding […]

Meeting Abstract 128.8  Tuesday, Jan. 7 15:15  Epigenetic regulation of alternative developmental trajectories in an annual killifish ROMNEY, A L*; PODRABSKY, J E; Portland State University; Portland State University arom2@pdx.edu The annual killifish, Austrofundulus limnaeus, is capable of entering into a state of metabolic and developmental dormancy during embryogenesis termed diapause. However, individuals may also follow an […]
