Meeting Abstract 46.5  Saturday, Jan. 5  Developmental evolution of insect metamorphosis: mimicking the temporal dynamics of visual system development in endopterygote insects by transient knock down of eye selector gene activity in the directly developing grasshopper Schistocerca americana FRIEDRICH, Markus*; DONG, Ying; Wayne State University, Detroit; UT Southwestern Medical Center, Dallas friedrichm@wayne.edu The adult compound eye of […]

Meeting Abstract 46.1  Saturday, Jan. 5  A Unifying Cell-Molecular Mechanism for the Co-evolution of Breathing, Locomotion and Metabolism TORDAY, John/S*; REHAN, Virender/K; UCLA; UCLA jtorday@labiomed.org We have identified a unifying, functional genomic, cell-molecular mechanism for the long-speculated co-evolution of breathing, locomotion and metabolism. Fluid distension of the developing mammalian lung determines the cell-molecular “switch” from the epithelial-mesenchymal […]

Meeting Abstract 45.3  Saturday, Jan. 5  The Role of Apoptosis in the Limbs of Urodeles and Anurans and in the Fins of Fish FRANSSEN, RA*; SHUBIN, NH; University of Chicago; University of Chicago franssen@uchicago.edu Our previous work revealed that the direct-developing salamander Desmognathus aeneus utilizes cell death during normal limb development, raising the possibility that apoptosis is […]

Meeting Abstract 45.4  Saturday, Jan. 5  Investigating the Lateral Somitic Frontier in the Mouse and Chick Scapula Using 3D Modeling SHEARMAN, R.M.*; TULENKO, F.J.; WINSLOW, B.B.; SFERLAZZO, M.; BURKE, A.C.; Wesleyan University; Wesleyan University; Wesleyan University; Wesleyan University; Wesleyan University rshearman@wesleyan.edu All limbed vertebrates have a pectoral girdle bridging the somite-derived axial column with the lateral-plate-derived fore-limb […]

Meeting Abstract 45.5  Saturday, Jan. 5  How similar are regeneration and fission in naidine annelids? BELY, A.E.**; ZATTARA, E.; BURTON, P.M.; SIKES, J.M.; NYBERG, K.G.; Univ. of Maryland, College Park abely@umd.edu Many animals with high regeneration potential can also reproduce by asexual agametic reproduction (eg, fission, budding). In groups such as annelids, both phylogenetic and developmental evidence […]

Meeting Abstract 45.2  Saturday, Jan. 5  Fish fingers and the origin of limbs: A compendium of recent progress DAVIS, M.C.; Kennesaw State University mdavi144@kennesaw.edu Recent comparative developmental studies and paleontological discoveries have provided us with exciting new insights into how the unique attributes of the tetrapod limb, namely digits, may have evolved. Developmental studies in the basal […]

Meeting Abstract 45.1  Saturday, Jan. 5  Appendage Regeneration in Animals: a framework for future research MAGINNIS, TL; The University of Montana, Missoula taramaginnis@austin.rr.com Many organisms have the ability to shed an appendage (autotomy) to escape a predator or fouled molting event. Despite its immediate advantage on survivorship, autotomy can have important consequences for locomotion, foraging, survivorship, and/or […]

Meeting Abstract 44.8  Saturday, Jan. 5  Reproductive allometry and the size-number trade-off for lizards WARNE, R.W.*; CHARNOV, E.L.; WOLF, B.O.; Univ. of New Mexico rwarne@unm.edu Fundamental to life history theory is the assumed inverse proportionality between the number of offspring and the resource allocation per offspring. Lizards have been model organisms for empirical tests of this theory […]

Meeting Abstract 44.3  Saturday, Jan. 5  Repeated Convergent Evolution of Parental Care Strategies within Xenotilapia, a Genus of Cichlid Fishes from Lake Tanganyika KIDD, M.R.*; HOFMANN, H.A.; The University of Texas at Austin; The University of Texas at Austin mckidd@earthlink.net The factors promoting the evolution of parental care strategies have been extensively studied in experiment and theory.
