KERNEY, Ryan; Harvard University: An unexpected role for the skeletal regulator Runx2 in anuran development The runt related transcription factor Runx2 has profound effects on differentiation of the vertebrate skeleton. In zebrafish, chicken, and mouse its mRNA is expressed in early skeletal condensations, and its active protein is critical for the formation of mineralized bone […]

THE GEOGRAPHIC DISTRIBUTION OF MYTILUS GALLOPROVINCIALIS AND M TROSSULUS IN NORTHERN JAPAN THE POTENTIAL ROLE OF TEMPERATURE
Meeting Abstract 16.3 Jan. 4 THE GEOGRAPHIC DISTRIBUTION OF MYTILUS GALLOPROVINCIALIS AND M. TROSSULUS IN NORTHERN JAPAN: THE POTENTIAL ROLE OF TEMPERATURE BRANNOCK, P M*; WETHEY, D S; HILBISH , T J; University of South Carolina brannockp@biol.sc.edu The Mytilus edulis (common blue mussel) complex consists of three sister species (M. edulis, M. galloprovincialis, and M. trossulus) that […]
Phylogeography of Pericharax heteroraphis (Porifera) from the Great Barrier Reef
Meeting Abstract 16.2 Jan. 4 Phylogeography of Pericharax heteroraphis (Porifera) from the Great Barrier Reef BENTLAGE, Bastian*; W�RHEIDE, Gert; Geoscience Centre of the University of G�ttingen, Germany; Geoscience Centre of the University of G�ttingen, Germany b_bentlage@gmx.net Resolving the biogeographic histories of tropical marine invertebrates remains a challenge. Sponges (Phylum Porifera) are well-suited models for such studies due […]
Host-Specificity of Sponge-Associated Unicellular Cyanobacteria, Candidatus Synechococcus spongiarum
Meeting Abstract 16.4 Jan. 4 Host-Specificity of Sponge-Associated Unicellular Cyanobacteria, Candidatus Synechococcus spongiarum ERWIN, P. M.*; THACKER, R. W.; University of Alabama at Birmingham; University of Alabama at Birmingham erwin@uab.edu Tropical and temperature marine sponges worldwide commonly associate with a unique lineage of symbiotic, unicellular cyanobacteria in the genus Synechococcus. These symbionts may benefit their host sponges […]
Cryptic biodiversity and phylogenetic patterns in the wide-ranging freshwater mussel genus Elliptio in southeastern North America
Meeting Abstract 16.1 Jan. 4 Cryptic biodiversity and phylogenetic patterns in the wide-ranging freshwater mussel genus Elliptio in southeastern North America. GANGLOFF, M. M.*; SIEFFERMAN, L. M.; HALANYCH, K. M.; Auburn University; Indiana University; Auburn University ganglmm@auburn.edu North America possess the world�s greatest diversity of freshwater mussels (Bivalvia: Unionidae and Margaritiferidae) yet nearly 70% of its ~300 […]
Colonization of Caves by Flightless Hawaiian Moths
Meeting Abstract 16.6 Jan. 4 Colonization of Caves by Flightless Hawaiian Moths MEDEIROS, M.J.; University of California, Berkeley m_j_m@berkeley.edu Cave-adapted fauna are hypothesized to colonize separate caves either via available underground connections, or in independent invasions which result in speciation events, because individuals of a cave-adapted species are unlikely to survive in the epigean environment. This may […]
A nuclear genome perspective on species boundaries and population structure in the sea anemone Aiptasia spp
Meeting Abstract 16.5 Jan. 4 A nuclear genome perspective on species boundaries and population structure in the sea anemone Aiptasia spp. XIANG, Y*; SANTOS, S.R.; Auburn University; Auburn University santos@auburn.edu Many marine invertebrates form mutualistic symbioses with dinoflagellates belonging to the genus Symbiodinium. To better understand these symbiotic associations, there is a need to develop model systems […]

Meeting Abstract 16.4 Thursday, Jan. 3 The nucleic acid sequence and gene structure of the hemoglobins of the brittle star Hemipholis elongata Say CHRISTENSEN, A.B.*; CHRISTENSEN, E.F.; SUKHODOLETS, M.V.; Lamar University, Beaumont, TX; Lamar University, Beaumont, TX; Lamar University, Beaumont, TX christenab@my.lamar.edu The burrowing brittle star Hemipholis elongata expresses two hemoglobins, fraction 1 and fraction 2 that […]
The effects of varying oxygen levels on size, growth, and development rate in the tobacco hornworm
Meeting Abstract 16.5 Thursday, Jan. 3 The effects of varying oxygen levels on size, growth, and development rate in the tobacco hornworm CEASE, Arianne*; ALBERT, Todd; VANDENBROOKS, John; DAVIDOWITZ, Goggy; HARRISON, Jon; Arizona State University; Arizona State University; Arizona State University; University of Arizona; Arizona State University acease@asu.edu Previous studies on fruitflies have shown that their body […]
Removal of cardiac shunt impairs growth in the American alligator
Meeting Abstract 16.2 Thursday, Jan. 3 Removal of cardiac shunt impairs growth in the American alligator EME, J.; GWALTHNEY, J.; OWERKOWICZ, T.; BLANK, J.M.; HICKS, J.W.*; UC Irvine; UC Irvine; UC Irvine; UC Irvine; UC Irvine jhicks@uci.edu Reptilian cardiac shunting is hypothesized to have adaptive importance in various physiological functions, e.g., inducing hypometabolism, metering lung oxygen during […]
