Meeting Abstract S3.1-2 Saturday, Jan. 4 08:30 Mechanisms of egg chamber elongation in Drosophila HORNE-BADOVINAC, Sally; The University of Chicago shorne@uchicago.edu During development, discrete organs and entire body plans emerge from the coordinate actions of individual cells. These complex morphogenetic events require dynamic regulation of cell shape, polarity, and adhesion across cell populations. My lab seeks to […]

How a single gene twists a snail
Meeting Abstract S3.2-2 Saturday, Jan. 4 11:00 How a single gene twists a snail KURODA, Reiko*; ABE, Masanori; Tokyo Univ. of Science; Tokyo Univ. of Science rkuroda@rs.tus.ac.jp Gastropod Lymnaea (L.) stagnalis has unique features, i.e. , the chirality, the sinistrality and the dextrality, is hereditary, determined by a single locus that functions maternally at the very early […]

Epithelium establishment and tentacle development in Nematostella vectensis
Meeting Abstract S3.2-3 Saturday, Jan. 4 11:30 Epithelium establishment and tentacle development in Nematostella vectensis GIBSON, Matt*; IKMI, Aissam; FRITZ, Ashleigh; RAGKOUSI, Katerina; Stowers Institute for Medical Research mg2@stowers.org Evolution of the capacity to form secondary epithelial outgrowths from the principal embryonic axes was a crucial innovation that potentiated the diversification of animal body plans. Nevertheless, the […]
Ectodermal inputs into patterning skeletogenesis
Meeting Abstract S3.3-4 Saturday, Jan. 4 15:00 Ectodermal inputs into patterning skeletogenesis LYONS, Diedre; MCINTYRE, Dan; MCCLAY, David R.*; Duke University; Duke University; Duke University dmcclay@duke.edu Sea urchin larvae produce a skeleton using a limited number of skeletogenic cells, usually either 32 or 64 cells depending on the species. Each skeletogenic cell is capable of producing any […]
Dynamics of Tissue Morphogenesis in Ascidians
Meeting Abstract S3.1-1 Saturday, Jan. 4 08:00 Dynamics of Tissue Morphogenesis in Ascidians MUNRO, E.M.*; HASHIMOTO, H.; ROBIN, F.R.; SHERRARD, K.M.; University of Chicago; University of Chicago; University of Chicago; University of Chicago emunro@uchicago.edu A key challenge in developmental biology is to understand how embryonic cells organize force production in space and time and how these forces […]

Meeting Abstract S2.3-2 Saturday, Jan. 4 14:00 The mechanisms of condition-dependent variation in melanin-based plumage color. D’ALBA, L.*; SPENCER, K.A.; VAN HEMERT, C.; HEIDINGER, B.J.; GILL, L.; EVANS, N.P.; MONAGHAN, P.; HANDEL, C.M.; SHAWKEY, M.D.; University of Akron; University of St. Andrews; USGS Alaska Science Center; University of Glasgow; Max Planck Institute for Ornithology; University of Glasgow; […]
The evolution of honest communication integrating social and physiological costs of ornamentation
Meeting Abstract S2.2-1 Saturday, Jan. 4 10:30 The evolution of honest communication: integrating social and physiological costs of ornamentation TIBBETTS, Elizabeth; University of Michigan tibbetts@umich.edu The honesty of animal communication systems is a central issue in behavioral and evolutionary biology. What prevents weak, low quality individuals from ‘cheating’ by signaling that they are strong? The general answer […]
Testing the Hamilton-Zuk hypothesis with 21st century genetic tools
Meeting Abstract S2.1-2 Saturday, Jan. 4 08:30 Testing the Hamilton-Zuk hypothesis with 21st century genetic tools BALENGER, Susan L.*; ZUK, Marlene; University of Minnesota, Twin Cities; University of Minnesota, Twin Cities sbalenge@umn.edu Hamilton and Zuk proposed a good genes model of sexual selection in which genetic variation (and, thus, selection) can be maintained when females prefer ornaments […]
Sex and disease in the city links between coloration, parasites, and urbanization
Meeting Abstract S2.3-1 Saturday, Jan. 4 13:30 Sex and disease in the city: links between coloration, parasites, and urbanization MCGRAW, KJ*; GIRAUDEAU, M; Arizona State University kevin.mcgraw@asu.edu Expanding urban conditions across the globe continue to impose unique environmental constraints on organisms. Condition-dependent sexually selected traits are useful for revealing how animals cope with stress, including anthropogenic disturbances. […]
