Meeting Abstract P3.50  Wednesday, Jan. 6  Dorsoventral patterning by BMP-gremlin interactions in segmental ectoderm of the leech Helobdella KUO, D.-H.*; WEISBLAT, D.A.; Univ. of California, Berkeley; Univ. of California, Berkeley dhkuo@berkeley.edu BMPs are evolutionarily conserved players in dorsoventral (DV) patterning of bilaterian embryos. They are best known acting as a morphogen in DV patterning of Drosophila and […]

Meeting Abstract P3.95  Wednesday, Jan. 6  Does nutritional state affect immune function in frogs? BLACK, Samuel J*; CRESPI, Erica J; Vassar College; Vassar College sablack@vassar.edu With emerging diseases threatening global amphibian populations, there is a need to understand the physiological mechanisms that influence susceptibility to infection in frogs and salamanders. Because variation in nutritional status is one […]

Meeting Abstract P3.8  Wednesday, Jan. 6  Do the exaggerated eye stalks of stalk-eyed flies have a predation cost? HUSAK, J.F.*; WORTHINGTON, A.M.; SWALLOW, J.G.; Univ. of South Dakota jerry.husak@usd.edu When opponents compete for access to an indivisible resource, signals can reduce costs associated with competition for that resource. Theory predicts that for signals to remain reliable in […]

Meeting Abstract P3.73  Wednesday, Jan. 6  Do constructional constraints influence cyprinid craniofacial diversification? HOLLINGSWORTH, P.R.*; HULSEY, C.D.; University of Tennessee; University of Tennessee phollin1@utk.edu Constraints on form should determine how organisms diversify. Due to competition for the limited space within the body, investment in adjacent structures may frequently represent an evolutionary compromise. For example, evolutionary tradeoffs between […]
