Meeting Abstract 21.1  Monday, Jan. 4  Novel Toadfish Swimbladder Morphology Creates Nonlinear Acoustic Complexities RICE, Aaron N.*; LAND, Bruce R.; BASS, Andrew H.; Cornell Univ.; Cornell Univ.; Cornell Univ. arice@cornell.edu Repeated morphological specializations of vocal structures across vertebrates have independently facilitated increased complexity in acoustic signals by generating nonlinear features. Such nonlinear acoustic complexity has been observed […]

Meeting Abstract 21.3  Monday, Jan. 4  Dietary protein content affects top-scent preference in meadow voles HOBBS, N. J.*; FERKIN, M. H.; University of Memphis nhobbs@memphis.edu Encountering over-marks, the overlapping scent marks of two different conspecifics, is a feature of olfactory communication for most terrestrial mammals. Previous studies have shown that when exposed to a same-sex over-mark, meadow […]

Meeting Abstract 21.3  Tuesday, Jan. 4  SoxE genes and the role of neural crest in cartilage evolution and development MCCAULEY, David W; University of Oklahoma dwmccauley@ou.edu Neural crest cells give rise to many vertebrate-specific structures. These cells arise during development along the dorsal aspect of the neural tube, undergo an epithelial to mesenchymal transition whereupon they migrate […]

Meeting Abstract 21.2  Tuesday, Jan. 4  Molecular and morphological development of the shark head cavity ADACHI, Noritaka*; KURATANI, Shigeru; RIKEN CDB Kobe; RIKEN CDB Kobe adasaurus@cdb.riken.jp The vertebrate head is considered as an evolutionary novelty. However, the head mesoderm is regarded a derivative of anterior somites in the ancestral chordate. Although, our head mesoderm consists of mesenchymal […]

Meeting Abstract 21.6  Tuesday, Jan. 4  Different ways to build a backbone: Notch regulation of somitogenesis in the lizard Anolis carolinensis is highly divergent from birds and mammals ECKALBAR, WL; INFANTE, C; DENARDO, D; LOSOS, J; RAWLS, A; WILSON-RAWLS, J; KUSUMI, K*; Arizona State Univ.; Harvard Univ.; Univ. of Georgia; Arizona State Univ.; Harvard Univ.; Arizona State […]

Meeting Abstract 21.5  Tuesday, Jan. 4  Comparative post-embryonic development of the cranial lateral line canal system in cichlid fishes: Temporal and spatial patterns DICKSON, JM*; WEBB, JF; University of Rhode Island; University of Rhode Island jdickson@my.uri.edu Morphogenesis of the lateral line canals is a key feature of dermatocranial development in bony fishes. Of the four types of […]

Meeting Abstract 21.3  Wednesday, Jan. 4  Through the looking glass: Are silvery fish safe from viewers with polarization vision? JOHNSEN, S. *; MARSHALL, N.J.; Duke Univ.; Univ. of Queensland sjohnsen@duke.edu Many coral reef and open-ocean fish have mirrored sides built from stacks of guanine crystals. Because the underwater light field is approximately symmetric around the vertical axis, […]

Meeting Abstract 21.6  Wednesday, Jan. 4  How do insect eggs avoid sunburns? POTTER, Kristen A.*; WOODS, H. Arthur; University of Montana, Missoula; University of Montana, Missoula kristen.potter@mso.umt.edu Ultraviolet radiation (UVR) from the sun damages DNA and causes acute health problems in living organisms. In response, organisms have evolved a suite of defenses against the sun’s harmful effects, […]
