RAHMAN, Y.J.*; STRATHMANN, R.R.; Univ. of California, Riverside; Univ. of Washington: Does scarcity of sites for egg deposition limit reproductive success? Estimated mortality rates are higher for planktonic larvae than for benthic embryos of marine invertebrates, but these estimates do not include difficulties associated with deposition of a benthic egg mass. One limitation on deposition […]

PLUMMER, J T; CROLL, R P; Dalhousie University; Dalhousie University: The development and role of the larval nervous system in bivalve molluscs. A comprehensive approach was used to investigate the morphology of the larval nervous system (LNS) in bivalves and how its neuronal subcomponents function to regulate behaviour. The development of the LNS in the […]

STONE, Jon R; HALL, Brian K; Dalhousie University; Dalhousie University: Software Development: Computer Simulated Neural Crest Cell Migration Neural crest is a germ layer that emerges at the boundary between prospective neural and epidermal ectoderms in craniates during development. Neural crest disassociates via an epithelial-mesenchymal transition to migrate as individual cells or cellular populations and […]

WEBB, J. F.; SHIREY, J. E.; Villanova University; Villanova University: Not Your Typical Teleost: Post-Embryonic Development of Neuromasts and Cranial Lateral Line Canals in the Zebrafish, Danio rerio The zebrafish, Danio rerio is a valuable model system for the study of fundamentals of vertebrate embryogenesis, but the post-embryonic development of zebrafish remains largely unexplored. We […]

IMLAY, G.J.*; PIRTLE, T.J.; NOREKIAN, T.P.; SATTERLIE, R.A.; Arizona State University; Arizona State University; Arizona State University; Arizona State University: Neuromuscular Morphology of Buccal Cones in Clione limacina The pteropod mollusk Clione limacina is a carnivorous predator, which feeds exclusively on actively swimming, shelled pteropods of the genus Limacina. Prey capture in Clione is achieved […]

France; RIKEN, CDB, Kobe: Developmental plan of the lamprey CNS; with reference to the vertebrate evolution To understand the vertebrate brain evolution, developmental pattern of lamprey neruomeres was studied . We have isolated cognates […]

ARTHUR, W.; University of Sunderland (UK): What determines the direction of evolutionary change? In this presentation, I examine the deceptively simple question posed in the title. I begin with a historical approach. I look at the views of Darwin and Wallace; Fisher and Ford; Gould and Lewontin. I then pose the question: is there a […]

ROBERT, Jason S.; Dalhousie University: Homeosis and Hopeless Monsters Beginning with William Bateson’s (1894) coining of the term ‘homeosis’, I trace significant events in the history of this concept throughout the twentieth century. Key episodes include Goldschmidt’s account of hopeful monsters (1940), early and contemporary developmental work on homeotic genes, and recent attempts to explain […]
