SCHILLING, TF; Univ. of California, Irvine: Craniofacial development and evolution in gnathostomes The skull and jaws were key innovations in vertebrate evolution. Much of this skeleton has a unique embryonic origin from cranial neural crest cells, unlike the more posterior axial and appendicular skeletons which are derived from mesoderm. How does the embryonic origin of […]

STOCK, D.W.; Univ. of Colorado, Boulder: Comparative studies of tooth development in teleost fishes My laboratory uses the zebrafish (Ostariophysi: Cypriniformes) as part of a three taxon statement for investigating the developmental genetic basis of macroevolution in the vertebrate dentition. Comparisons of gene expression, regulation and function are carried out with an additional ostariophysan, the […]

FETCHO, J.R.; Cornell University: The comparative biology of spinal motor networks in zebrafish After decades of work, the spinal motor networks for swimming and escape in fishes and amphibians are among the best understood motor circuits in vertebrates. These circuits in anamniotes have much in common, but linking their cell types to the circuits in […]

MAYDEN, R. L.*; CONWAY, K.; CHAMBERLAIN, S.; HASKINS, M.; SCHNEIDER, L.; SUDKAMP, M.; TANG, K; WOOD, R. M.; Saint Louis University, St. Louis, Missouri: Phylogenetic Relationships of Danio within the Order Cypriniformes: A Framework for Comparative and Evolutionary Studies of a Model Species. The evolutionary relationships of species of Danio and the monophyly and phylogenetic […]

HALPERN, ME*; KUAN, YS; SANTHAKUMAR, K; GAMSE, JT; Carnegie Institution; Carnegie Institution; Carnegie Institution; Vanderbilt University: Left-Right Asymmetry in the Zebrafish Brain In the human cortex, the left hemisphere functions differently from the right. How this specialization arises and the corresponding anatomical substrates are poorly understood. The zebrafish epithalamus is a valuable model for exploring […]

KOCHER, Thomas D; University of New Hampshire: From Natural Systems to Laboratory Models: Comparative Genomics of Teleost Fishes The thousands of species of cichlid fishes in the lakes of East Africa are not only an evolutionary wonder, but also a natural mutant screen for phenotypes ranging from morphology to behavior. To facilitate genetic analysis of […]

COOPER, Mark S*; VIRTA, Valerie M; University of Washington; University of Washington: Evolution of Gastrulation in the Actinopterygian (Ray-Finned) Fishes This presentation reviews evolutionary changes in the gastrulation of ancient lineages of Actinopterygian fish. Cellular features of zebrafish gastrulation will be interpreted from an evolutionary perspective, focusing on the ontogenetic innovations that resulted in the […]

WEBB, J.F.; Villanova University: Development of the Lateral Line System in Teleost Fishes: Zebrafish and Beyond The lateral line system of teleost fishes provides many opportunities for the investigation of fundamental questions in evolutionary developmental biology. The lateral line system is composed of, not a bilateral pair of cranial sensory organs, but a spatial array […]

POSTLETHWAIT, John/H*; YAN, Yi-Lin; AMORES, Angel; CRESKO, Bill; SINGER, Amy; RUBIN, David; University of Oregon, Eugene, OR; Illinois State University, Normal, IL: Consequences of genome duplication for the evolution of developmental mechanisms in teleost fish Genome amplification, probably as a result of genome duplication, occurred prior to two key nodes of chordate evolution: the origin […]
