Meeting Abstract 39.1  Monday, Jan. 5  Gravidity degrades escape performance in threespine stickleback MCGEE, M.D.; Univ. of California, Davis mcgee@ucdavis.edu Traits that increase reproductive success while increasing predation risk have been well documented in males, but a similar phenomenon may also exist in females. Just as males with sexually selected ornaments may experience an increased predation rate, […]

Meeting Abstract 39.3  Monday, Jan. 5  Caudal fin shape modulation and control during acceleration, braking, and backing maneuvers in bluegill sunfish, Lepomis macrochirus FLAMMANG, B.E.*; LAUDER, G.V.; Museum of Comparative Zoology, Harvard University; Museum of Comparative Zoology, Harvard University bflammang@oeb.harvard.edu Evolutionary patterns of intrinsic caudal musculature show that control of the dorsal lobe of the tail evolved […]

Meeting Abstract 39.5  Monday, Jan. 5  Cartilaginous vertebral columns: mechanical responses to external loads and internal joint pressurization PORTER, ME*; LONG, JH; Vassar College; Vassar College meporter@vassar.edu While we have shown that vertebral number and centra shape are important predictors of body curvature in cartilaginous fishes during powered turns, morphological correlates predict only about 50% of body […]

Meeting Abstract 39.1  Tuesday, Jan. 5  Origin ad evolution of the coral reef fish fauna SANTINI, F.*; ALFARO, M.E.; Univ. of California, Los Angeles; Univ. of California, Los Angeles santini@eeb.ucla.edu Coral reefs occupy less than 2% of marine surface, yet about 40% of the approximately 170000 marine fish species live predominantly or exclusively on coral reefs. Earlier […]

Meeting Abstract 39.2  Tuesday, Jan. 5  Microeukaryotes and the masters of miniaturization: Diversification in marine sand RUNDELL, Rebecca J.*; LEANDER, Brian S.; University of British Columbia rrundell@interchange.ubc.ca Marine interstitial environments harbor an extraordinary diversity of coexisting microeukaryotic lineages collectively called “meiofauna.” The extensive geographic distribution and long geological history of interstitial environments suggest that knowledge of meiofaunal […]

Meeting Abstract 39.3  Tuesday, Jan. 5  Atmospheric Oxygen Influences on the Size of Modern and Fossil Insects VANDENBROOKS, John M.*; HARRISON, Jon F.; Arizona State University; Arizona State University jvandenb@asu.edu Recent modeling has estimated that over the last 500 million years atmospheric oxygen has varied from as low as 12% in the Triassic to as high as […]

Meeting Abstract 39.2  Wednesday, Jan. 5  Reconstructing growth of the basal archosauromorph Trilophosaurus WERNING, S*; IRMIS, RB; Univ of California, Berkeley; Univ of Utah; Utah Museum of Natural History swerning@berkeley.edu Despite extensive research on the evolution of bird-line archosaur growth strategies, the basal condition for archosaurian growth rates, bone histology, and ontogenetic changes in surface morphology remain […]
