Meeting Abstract S9.8  Tuesday, Jan. 6  Ecoimmunology: The Organism in Context FRENCH, S.S.*; MOORE, M.C.; DEMAS, G.E.; Indiana University; Arizona State University; Indiana University sufrench@indiana.edu A major challenge in integrative biology is understanding the mechanisms by which organisms regulate trade-offs among various functions competing for limiting resources. Key among these competing processes is the production of offspring […]

Meeting Abstract S9.7  Tuesday, Jan. 6  Early life environment influences on neuroimmune interactions and behavior in adulthood. BILBO, S.D.; Duke University staci.bilbo@duke.edu Events within the perinatal environment have significant consequences for the development and function of physiological systems throughout life, a phenomenon termed perinatal programming. For instance, early life exposure to infectious agents influences reactivity to stress, […]

Meeting Abstract S9.3  Tuesday, Jan. 6  A Hassle A Day May Keep The Pathogens Away: The Fight-Or-Flight Stress Response And The Augmentation of Immune Function DHABHAR, F.S.; Stanford University, Stanford, CA. dhabhar@gmail.com Although stress has a deservedly bad reputation, it is important to appreciate that a psycho-physiological stress response is one of nature’s fundamental survival mechanisms. Without […]

Meeting Abstract S9.9  Wednesday, Jan. 6  Understanding the non-spiral members of the clade Spiralia: The development of the digestive system of the brachiopod Terebratalia transversa HEJNOL, A*; PASSAMANECK, YQ; MARTINDALE, MQ; Sars International Centre for Marine Molecular Biology, University of Bergen, Norway, Kewalo Marine Laboratory, University of Hawaii, Honolulu, 96813, USA; Kewalo Marine Laboratory, University of Hawaii, […]

Meeting Abstract S9.6  Wednesday, Jan. 6  The role of the polar lobe and intracellular signaling in cell fate specification of the mud snail Ilyanassa. GHARBIAH, M; NAKAMOTO, A; NAGY, L*; University of Arizona lnagy@email.arizona.edu The early embryo of the mud snail Ilyanassa is characterized by the presence of a polar lobe, a large anucleate structure protruded during […]

Meeting Abstract S9.10  Wednesday, Jan. 6  The left-right axis. Generating asymmetries in snail development. GRANDE, Cristina; Centro de Biología Molecular Severo Ochoa cgrande@cbm.uam.es Although most animals are bilaterians, many develop specific asymmetries along the left-right axis like the asymmetric placing of single organs, directional asymmetry in appendages and the coiling of the snail shells. Despite its key […]

Meeting Abstract S9.4  Wednesday, Jan. 6  The invention of the pilidium larva in an otherwise perfectly good spiralian phylum Nemertea. MASLAKOVA, S.A.; Oregon Institute of Marine Biology, U. of Oregon svetlana@uoregon.edu The nemertean pilidium is one of the most unusual larval forms among the spiralians. It is restricted to the monophyletic clade Pilidiophora. All other nemerteans have […]

Meeting Abstract S9.7  Wednesday, Jan. 6  The development of the mesentoblast in the gastropod Crepidula fornicata MARTINDALE, Mark Q.*; LEE, Patricia; HENRY, Jonathan Q.; Kewalo Marine Lab, Univ. Hawaii mqmartin@hawaii.edu One of the hallmarks of the spiralian cleavage program is the ability to identify and compare the development of homologous cells in embryos from disparate taxonomic groups. […]

Meeting Abstract S9.1  Wednesday, Jan. 6  The complete cell lineage of the polychaete annelid Capitella teleta MEYER, N. P.; BOYLE, M. J.; MARTINDALE, M. Q.; SEAVER, E. C.*; University of Hawaii; University of Hawaii; University of Hawaii; University of Hawaii seaver@hawaii.edu The polychaete annelid Capitella teleta (formerly Capitella sp. I) exhibits a spiral cleavage program, and has […]

Meeting Abstract S9.5  Wednesday, Jan. 6  Symmetry makers and symmetry breakers: the transition of a spiral cellular arrangement to bilateral symmetry in early embryos of Platynereis dumerilii SCHNEIDER, Stephan Q; Iowa State University sqs@iastate.edu Embryonic development shapes the size of subsequent morphological features e.g. of larvae and/or adults by specifiying areas and/or progenitor cells of different size […]
