Meeting Abstract 31.5 Jan. 5 Chronic stress alters the avian cardiovascular and glucocorticoid stress response CYR, N.E.*; ROMERO, L.M.; Tufts University; Tufts University npoiri01@tufts.edu The activation of the stress response to noxious stimuli is essential to survival in animals, however long term activation of the stress response may have critical medical and physiological consequences. To better understand […]

Carotenoids accumulated in intertidal mussels as a potential response to oxidative stress
Meeting Abstract 31.3 Jan. 5 Carotenoids accumulated in intertidal mussels as a potential response to oxidative stress PETES, L.E.**; MENGE, B.A.; Oregon State University; Oregon State University petesl@science.oregonstate.edu Globally, marine invertebrates are under increasing stress due to steadily rising water and air temperatures. High temperatures and desiccation lead to oxidative stress, especially in the stressful high zone […]
The cellular basis of pharyngeal skeleton growth and metamorphosis in frogs
Meeting Abstract 31.4 Friday, Jan. 4 The cellular basis of pharyngeal skeleton growth and metamorphosis in frogs ROSE, C.S.*; SMITH, A.; TRACY, J.; James Madison University; James Madison University; James Madison University rosecs@jmu.edu The Meckel�s cartilage (MC), ceratohyal (CH), and branchial arch cartilages (BA) of Xenopus laevis grow isometrically in pre- and prometamorphosis, and undergo distinct shape […]
Getting a leg up the evolution of novel abdominal appendages in sepsid flies
Meeting Abstract 31.6 Friday, Jan. 4 Getting a leg up: the evolution of novel abdominal appendages in sepsid flies BOWSHER, J.H.*; NIJHOUT, H.F.; NAGY, L. M.; University of Arizona; Duke University; University of Arizona jhb4@email.arizona.edu A major goal of the recent re-synthesis of developmental and evolutionary biology is to understand how evolutionary changes in the molecular processes […]
Generation of a Xenopus col2a1 reporter for cartilage-specific transgene expression
Meeting Abstract 31.5 Friday, Jan. 4 Generation of a Xenopus col2a1 reporter for cartilage-specific transgene expression KERNEY, Ryan; Dalhousie University ryankerney@gmail.com This study examines enhancer regions of the collagen 2 alpha1 (col2a1) first intron in Xenopus tropicalis that are capable of driving transgenic EGFP expression in Xenopus laevis when connected to a minimal promoter. The EGFP expressions […]
Evolutionary Divergence of Pharyngeal Arch Specification in Teleosts
Meeting Abstract 31.3 Friday, Jan. 4 Evolutionary Divergence of Pharyngeal Arch Specification in Teleosts LE PABIC, Pierre*; SCEMAMA, Jean-Luc; STELLWAG, Edmund; East Carolina University stellwage@ecu.edu We are interested in the effects of differential gene retention on Hox paralog group 2 (Hox PG2) function following a post-genome duplication event that occurred during the incipient stages of teleost evolution. […]
Deconstructing Deuterosomes Before a Head
Meeting Abstract 31.1 Friday, Jan. 4 Deconstructing Deuterosomes: Before a Head SWALLA, B.J.; University of Washington, Seattle bjswalla@u.washington.edu Deuterostomia consists of related phyla that display distinct adult body plans, so present an excellent group of animals to study the evolution of larval and adult body plans. Echinodermata, Hemichordata and Xenoturbellida make up the Xenoambulacraria, while the Chordata […]
A New Iniopterygian (Class Chondrichthyes) from the Mississippian Bear Gulch Limestone of Montana and New Insights into the Early Chondrichthyan Neurocranial Design
Meeting Abstract 31.2 Friday, Jan. 4 A New Iniopterygian (Class Chondrichthyes) from the Mississippian Bear Gulch Limestone of Montana and New Insights into the Early Chondrichthyan Neurocranial Design. GROGAN, E.D.*; LUND, R; Saint Joseph’s University, Philadelphia, PA; Carnegie Museum, Pittsburgh egrogan@sju.edu The Iniopterygii are Paleozoic chondrichthyans that are poorly understood. Morphological evidence of the form code-named Iniop3 […]
Understanding the role of lysozyme in birds physiological interactions between experimental immune enhancement and challenge
Meeting Abstract 31.1 Monday, Jan. 5 Understanding the role of lysozyme in birds: physiological interactions between experimental immune enhancement and challenge. MATSON, K.D.*; HORROCKS, N.P.C.; VERSTEEGH, M.A.; TIELEMAN, B.I.; University of Groningen; University of Groningen; University of Groningen; University of Groningen k.d.matson@rug.nl In pigeons, we examined the interactions between experimental immune enhancement and challenge. Immune enhancement took […]
Form and function of a novel metalloproteinase from the Eastern Oyster, Crassostrea virginica
Meeting Abstract 31.2 Monday, Jan. 5 Form and function of a novel metalloproteinase from the Eastern Oyster, Crassostrea virginica PROESTOU, DA*; SALGER, S; VAUGHN, C; GOMEZ-CHIARRI, M; University of Rhode Island dpro1791@postoffice.uri.edu Among vertebrates, matrix metalloproteinases (MMPs) are a well-studied family of enzymes. They are zinc-dependent, degrade the extracellular matrix, and play a critical role in many […]
