Meeting Abstract 34.4  Friday, Jan. 4  Robustness of gastrulation to biomechanical variation among embryos of Xenopus laevis VON DASSOW, M.**; DAVIDSON, L.A.; Univ. of Pittsburgh; Univ. of Pittsburgh mvondass@yahoo.com Embryo mechanical properties are important in morphogenesis because tissue movements are a function of both the forces exerted by cells and the mechanical properties of the tissues on […]

Meeting Abstract 34.1  Friday, Jan. 4  Neural development in the polychaete annelid Capitella sp. I SEAVER, Elaine C.*; MEYER, Neva P.; University of Hawaii; University of Hawaii seaver@hawaii.edu A key step during early central nervous system development is fate specification of neural precursor cells, which generate the entire brain and nerve cord. To date, the basic mechanisms […]

Meeting Abstract 34.2  Monday, Jan. 5  The Evolution, Development, and Genetics of Jaw Asymmetry in Lake Tanganyika Scale Eating Cichlids STEWART, T.A.*; ALBERTSON, R.C.; Syracuse University tastew01@syr.edu Perissodus microlepis, Perissodus straeleni, and Perissodus paradoxus are cichlid fishes native to Lake Tanganyika in central Africa, which forage through lepidophagy, or scale-feeding. Each species is laterally asymmetrical, their heads […]

Meeting Abstract 34.3  Monday, Jan. 5  Ectopic expression of Fgf ligands results in supernumerary and fused teeth in zebrafish larvae JACKMAN, W.R.*; STOCK, D.W.; Bowdoin College; Univ. of Colorado wjackman@bowdoin.edu Fibroblast growth factor (Fgf) signaling is required for teeth to progress beyond the earliest stages of development in both mammals and zebrafish. Whether Fgf signaling is sufficient […]
