Meeting Abstract 15.2  Jan. 4  Density-dependent effects on hatching success in olive ridley sea turtles HONARVAR, Shaya*; O’CONNOR, Michael P.; SPOTILA, James R.; Drexel University; Drexel University; Drexel University sh333@drexel.edu Historically, the olive ridley arribada at Playa Nancite, Costa Rica has been one of the largest arribadas in the eastern Pacific with 100,000 nesting females in a […]

Meeting Abstract 15.3  Thursday, Jan. 3  Morphological integration and the role of pleiotropy in the evolution of primate hands and feet ROLIAN, Campbell; Harvard University rolian@fas.harvard.edu Morphological integration is an emergent property of complex organisms whereby certain phenotypic traits covary more strongly than others because of shared functions and/or developmental phenomena such as pleiotropy. The digits of […]

Meeting Abstract 15.2  Thursday, Jan. 3  Developmental mechanisms of plasticity: cellular response to muscle function in skeletal traits YOUNG, R; University of Arizona rlyoung@email.arizona.edu Selection for local adaptation, especially to widely fluctuating environments, often favors greater sensitivity of development to environmental inputs. This sensitivity or plasticity in trait development is often noted across environments; however, the developmental […]

Meeting Abstract 15.1  Thursday, Jan. 3  Can Modular Variation Affect Patterns of Morphological Disparity in the Rodent Mandible? MARQUEZ, E.J.; UNIV. OF MICHIGAN, ANN ARBOR emarquez@umich.edu The relationship between modularity and disparity of mandible shape was studied in 11 species of oryzomyine rodents, using geometric morphometrics. A novel approach in which explicit expectations from hypotheses of modularity […]

Meeting Abstract 15.6  Sunday, Jan. 4  The Hydrodynamic Wake of Two Species of Swimming Krill YEN, J.*; CATTON, K.; WEBSTER, D.; Georgia Institute of Technology, Biology; Georgia Institute of Technology, Civil and Environmental Engineering; Georgia Institute of Technology, Civil and Environmental Engineering jeannette.yen@biology.gatech.edu Krill are often found in unorganized swarms or coordinated schools depending on the species. […]

Meeting Abstract 15.2  Sunday, Jan. 4  Solving a low-Reynolds number conundrum: How fast should diatoms sink? MIKLASZ, K.A.; Hopkins Marine Station kmiklasz@stanford.edu Diatoms are one of the oceans primary producers. We would like to understand the movement and flux of diatoms through the water column, or how fast diatoms of different sizes should sink. Fluid dynamic theory […]

Meeting Abstract 15.3  Sunday, Jan. 4  Locomotory Biomechanics of Antarctic Krill MURPHY, D. W.*; WEBSTER, D. R.; KAWAGUCHI, S.; KING, R.; YEN, J.; Georgia Institute of Technology; Georgia Institute of Technology; Australian Antarctic Division; Australian Antarctic Division; Georgia Institute of Technology dwmurphy@gatech.edu Antarctic krill (Euphausia superba) are the keystone species of the Antarctic food web, yet little […]

Meeting Abstract 15.5  Sunday, Jan. 4  Kinematics and hydrodynamics among ranid and pipid frogs RICHARDS, Christopher T.*; BIEWENER, Andrew A.; Harvard University richards@fas.harvard.edu Recent work has addressed hindlimb kinematics of swimming frogs in the context of muscle function and hydrodynamics. However, there are no detailed studies linking time-varying joint kinematics with the propulsive function of anuran feet. […]

Meeting Abstract 15.4  Sunday, Jan. 4  Diving wasps: swimming and flying at very low Reynolds numbers MILLER, LA*; SANTHANAKRISHNAN, A; University of North Carolina at Chapel Hill lam9@email.unc.edu The family Mymaridae (fairyflies) is comprised of tiny parasitoid wasps that include the smallest of all insects. The females of several species in this family are known to dive […]
