Meeting Abstract 14.4  Sunday, Jan. 4  Impacts of molt-inhibiting organochlorines on epidermal ecdysteroid signaling in the fiddler crab, Uca pugilator, in vitro MENG, Yanling; ZOU, Enmin*; Nicholls State University, Thibodaux, LA; Nicholls State University, Thibodaux, LA em.zou@nicholls.edu Organochlorine compounds (OCs) are widely used as industrial and agricultural chemicals. Because of their lipophilicity, these chemicals can readily accumulate […]

Meeting Abstract 13.2  Sunday, Jan. 4  Evolution of vertebrate chondrogenesis: Lessons from lampreys MCCAULEY, DW; University of Oklahoma, Norman dwmccauley@ou.edu The appearance of neural crest cells in early vertebrates has been suggested to have been a key event critical to vertebrate complexity. Gene duplication has also been suggested to play a crucial role in increased vertebrate diversity […]

Meeting Abstract 13.4  Sunday, Jan. 4  Body Wall Formation in Lamprey TULENKO, FJ*; KUSAKABE, R; KURATANI, S; BURKE, AC; Wesleyan University; Kobe University; RIKEN Center for Developmental Biology; Wesleyan University ftulenko@wesleyan.edu Patterning of the musculoskeletal system from embryonic mesoderm has diverged considerably over more than 350 million years of vertebrate evolution, resulting in extraordinary morphological variation across […]

Meeting Abstract 13.3  Sunday, Jan. 4  A long-term somite fate map using GFP-transgenic axolotls PIEKARSKI, N.*; OLSSON, L.; Friedrich-Schiller-Universitaet Jena, Germany; Friedrich-Schiller-Universitaet Jena, Germany nadine.piekarski@uni-jena.de Derivatives of single somites are well studied using quail-chick chimeras. In order to investigate comparative aspects of single somite fate, we have extended this work to a urodele amphibian, the Mexican axolotl. […]

Meeting Abstract 12.5  Sunday, Jan. 4  The role of Fgf8 in the origin of interdigital webbing in cetaceans COOPER, Lisa Noelle*; THEWISSEN, J.G.M.; NEOUCOM; NEOUCOM l.noelle.cooper@gmail.com Cetaceans (whales, dolphins, and porpoises) evolved a soft-tissue flipper that encases the bony digits and generates lift during feeding maneuvers and locomotion. This flipper impedes individual digital movement and creates a […]

Meeting Abstract 12.3  Sunday, Jan. 4  The evolution of developmental patterns in the Anolis skeleton SANGER, TJ*; MAHLER, DL; LOSOS, JB; ABZHANOV, A; Harvard Univeristy tsanger@oeb.harvard.edu One of the major challenges in modern biology is elucidating both the ultimate and proximate mechanisms of adaptive phenotypic evolution. Caribbean Anolis lizards exhibit numerous morphological specializations that are well understood […]
