Meeting Abstract S5.2  Tuesday, Jan. 5  Sponge regeneration in ecological context WULFF, Janie; Florida State University wulff@bio.fsu.edu Creative application of new imaging and molecular techniques to sponge larval development and a variety of sub-organismal levels in adult sponges has recently demonstrated greater potential for integration and co-ordination of developmental and physiological responses within individuals than had previously […]

Meeting Abstract S5.4  Tuesday, Jan. 5  Regeneration: a framework for future research MAGINNIS, Tara L; The University of Texas at Austin 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 reproduction. […]

Meeting Abstract S5.0  Tuesday, Jan. 5  Introduction BELY, A; LINDSAY, S;

Meeting Abstract S5.10  Tuesday, Jan. 5  Exploring Hydra regeneration and budding with genomics, transgenics, and chemical genetics STEELE, Rob; University of California, Irvine resteele@uci.edu Hydra was first described in 1702 by van Leeuwenhoek, who noted the presence of buds on the animal. In 1744, Trembley published his memoirs, in which he described Hydra’s ability to reproduce asexually […]

Meeting Abstract S5.5  Tuesday, Jan. 5  Evolutionary morphology of regenerative abilities among crinoids: a paleontological perspective GAHN, Forest J*; BAUMILLER, Tomasz K; Brigham Young Univeristy-Idaho; University of Michigan gahnf@byui.edu The fossil record demonstrates that crinoids have had the capacity to regenerate lost body parts since the Ordovician. This ability has been recognized in all parts of the […]

Meeting Abstract S5.6  Tuesday, Jan. 5  Evolutionary loss of animal regeneration: pattern and process BELY, A.E.; Univ. of Maryland, College Park abely@umd.edu Regeneration ability has been greatly restricted or altogether lost numerous times among animals. Yet despite its prevalence, regeneration loss and the mechanisms by which it occurs remain poorly studied. I will provide a phylogenetic overview […]

Meeting Abstract S5.7  Tuesday, Jan. 5  Evolution of mechanisms underlying limb regeneration in salamanders BROCKES, Jeremy P; UCL j.brockes@ucl.ac.uk The most extensive regenerative ability among adult vertebrates is found in various species of salamander. In our work on the mechanism of limb regeneration we have identified a protein called Prod 1 which seems to be central to […]

Meeting Abstract S5.1  Tuesday, Jan. 5  Ecology of injury and regeneration in marine benthic invertebrates: from individuals to ecosystems LINDSAY, S.M.; University of Maine, Orono slindsay@maine.edu Many marine invertebrates are able to regenerate lost tissue following injury, but regeneration can come at a cost to individuals in terms of reproduction, behavior and physiological condition, and can have […]

Meeting Abstract S5.3  Tuesday, Jan. 5  Costs of arm loss and regeneration in stellate echinoderms LAWRENCE, J.M.; Univ. of South Florida lawr@cas.usf.edu The cost of regeneration is greater in asteroids than in crinoids and ophiuroids because of greater development of the body wall and presence of gonads and pyloric caeca. In addition, arm loss occurs at locations […]

Meeting Abstract S5.9  Tuesday, Jan. 5  Bioelectric Events and Vertebrate Appendage Regeneration TSENG, A*; LEVIN, M; Tufts University; Tufts University aisun.tseng@tufts.edu It has long been known that bioelectrical events play a causal role in vertebrate appendage regeneration. However, the underlying mechanisms have only recently begun to be revealed using the anuran frog, Xenopus laevis. Xenopus is able […]
