BININDA-EMONDS, O. R. P.*; JEFFERY, J. E.; DONOHOE, A.; RICHARDSON, M. K.; Technical University of Munich; Leiden University; University College London; Leiden University: Reconstructing phylogenetic relationships from developmental timing data There has been increasing interest recently in analyzing developmental timing data in a phylogenetic framework. Several studies have now shown that changes in such timing […]

GURALNICK, R.P.; JEFFREY, J; University of Colorado; Leiden University: Re-evaluating phylogenetic hypotheses generated from cell-lineage data using event-pairing analysis In all animals in the super-phylum Eutrochozoa (containing phyla such as Annelida, Mollusca), the cell formation events that occur from formation of zygote to gastrulation are relatively stereotyped. The major visible differences in early development are […]

GALLUT, C; Universit� Pierre et Marie Curie: Parsimony inference from genome organisation Phylogenetic parsimony analyses rely on homologous characters comparison, there by identifying homologies is an inescapable first step, the second step is to code these homologies in a suitable way to perform the analyse. It is very much the same for phylogenetic analyses based […]

JEFFERY, J.E.; BININDA-EMONDS, O.R.P.; COATES, M.I.; RICHARDSON, ,M.K.; International School of Amsterdam, The Netherlands; Tech. Univ. of Munich; Univ. of Chicago, USA; Univ. of Leiden, The Netherlands: Optimising Heterochrony onto Phylogenetic Trees Event-pairing is a powerful method for encoding developmental timing data, in order to optimise them on phylogenetic trees. For each species the method […]

COLBERT, M.W.; The University of Texas at Austin: Ontogenetic Sequence Analysis: a parsimony-based method for characterizing developmental hierarchies Most animals lack longitudinal data documenting sequential changes during ontogeny. Accordingly, sequences must be estimated using cross-sectional samples that have been ordered into series based on age or maturity criteria. Size has been the primary criterion for […]

SPICER, J I; Univ. of Plymouth, UK: Following changes in timing during the development of physiological function There is increased interest in studying and indeed quantifying the changes in timing that take place during the development of physiological function in animals investigated both as a within-individual (ontogenic) and a between-species (phylogenetic) phenomenon. The recent appearance […]

WANG, L.-S.; JANSEN, R.K.; MORET, B.M.E.; RAUBESON, L.A.; WARNOW, T.; University of Pennsylvania; University of Texas at Austin; University of New Mexico; Central Washington University; University of Texas at Austin: Distance-Based Genome Rearrangement Phylogeny Evolution operates on whole genomes through mutations that change the order and strandedness of genes within the genomes. These events are […]

WAGNER, P.J.; The Field Museum, Chicago: Ancestral species in the fossil record Given that sampling and species durations both are finite, it is inevitable that we will sample ancestor-descendant pairs from the fossil record. How many we expect to find depends on sampling rates, which vary considerably among and within taxa, and other factors such […]

Meeting Abstract S8.4  Tuesday, Jan. 6  Zebrafish developmental genetics and the mechanisms of dental evolution STOCK, D.W.; University of Colorado, Boulder David.Stock@Colorado.edu Dentition in fishes exhibits enormous diversity in shape, number, and location of individual teeth. The developmental and genetic mechanisms underlying this diversity are just beginning to be characterized through studies in a variety of taxa. […]

Meeting Abstract S8.7  Tuesday, Jan. 6  The diversity of cichlid vision CARLETON, Karen L; University of Maryland kcarleto@umd.edu Cichlids are well known for their diverse morphologies and color patterns. We have found that their visual systems are also highly diverse with some of the largest known differences in visual sensitivities amongst closely related species. This diversity is […]
