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. Uniquely for this group the […]

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 […]

Meeting Abstract 128.7  Tuesday, Jan. 7 15:00  Dimorphic Development in Streblospio benedicti: Characterizing key morphological shifts between larval types using hybrid crosses ZAKAS, C*; ROCKMAN, MV.; New York University; New York University christinazakas@gmail.com Mechanisms of early development can constrain body plan evolution, but the extent to which these developmental constraints shape larval morphology, and thus suites of […]

Meeting Abstract 128.5  Tuesday, Jan. 7 14:30  Development in the invasive colonial ascidian Didemnum vexillum IRVINE, SQ*; STEPHENS, CE; Unv. of Rhode Island; Unv. of Rhode Island steven.irvine@uri.edu D. vexillum is an encrusting invasive colonial tunicate. It shares a peculiar form of asexual development, called pyloric budding, with other didemnid ascidians. In pyloric budding two buds form […]

Meeting Abstract 128.2  Tuesday, Jan. 7 13:45  Development and life cycle evolution in the sea nettle jellies (Pelagiidae) HELM, RR*; DUNN, CW; Brown University rebecca.rae.helm@gmail.com Life cycle evolution is difficult to study because many instances of life cycle transition occur at the base of diverse lineages. One exception is the mauve stinger jelly Pelagia noctiluca, which has […]

Meeting Abstract 128-4  Thursday, Jan. 7 14:15  Rapid autophagic involution of the tsetse fly milk gland is critical to the efficiency of lactation and population growth BENOIT , J.
