Meeting Abstract 22.3  Sunday, Jan. 4  The highly divergent developmental pathways of marsupial fore- and hind limbs: Evidence from the AER DOROBA, C.K.*; SEARS, K.E.; University of Illinois; University of Illinois carolyn.doroba@gmail.com Marsupials give birth after short gestations to neonates that must immediately crawl to the teat using only their precociously developed forelimbs (FL). As their hind […]

Meeting Abstract 22.1  Sunday, Jan. 4  Monotreme postcranial ontogeny and the evolution of mammalian skeletal development WEISBECKER, Vera*; SANCHEZ-VILLAGRA, Marcelo R; Cambridge University; Universitaet Zuerich vwei07@esc.cam.ac.uk Mammalian postcranial diversity and development is often discussed with view to a potential relationship of mammalian reproduction with postcranial ontogeny. However, data on monotremes, representing the earliest diverging extant mammalian clade, […]

Meeting Abstract 22.4  Sunday, Jan. 4  Modularity and integration of mandibular size and shape ZELDTICH, M.L.*; SWIDERSKI, D.L.; WOOD, A.R.; Univ. of Michigan, Ann Arbor; Univ. of Michigan, Ann Arbor; Univ. of Michigan, Ann Arbor zelditch@umich.edu The mammalian mandible is a developmentally modular, functionally integrated system. Whether morphological integration can evolve to match functional integration may depend […]

Meeting Abstract 22.6  Sunday, Jan. 4  Evolution of modularity: selection for trait disassociation PAVLICEV, M*; CHEVERUD, JM; WAGNER, GP; Washington University, St. Louis; Washington University, St. Louis; Yale University, New Haven pavlicev@pcg.wustl.edu Genetic variance in intertrait relationship provides potential for evolutionary change in integration of phenotypic units and can supply a model for the evolution of modularity. […]

Meeting Abstract 22.5  Sunday, Jan. 4  Does Morphological Integration Have Macroevolutionary Implications? HABER, Annat; University of Chicago annat@uchicago.edu The study of morphological integration has received increasing attention in evolutionary biology in the last two decades. Based on previous theoretical and empirical work, an association is expected between ontogenetic integration within a species and that species potential to […]

Meeting Abstract 22.2  Sunday, Jan. 4  Covariation, disparity and constraints in marsupial and eutherian limb evolution SEARS, K.E.; University of Illinois ksears@life.uiuc.edu Marsupial newborns complete a life-or-death crawl to the teat, powered solely by their forelimbs. As a result, marsupial fore- and hind limbs have disparate functional requirements early in development. In contrast, eutherians develop largely in […]

Meeting Abstract 21.6  Sunday, Jan. 4  Wing stiffness affects mean advective flows of Manduca sexta, with wing overlap a potential contributor MOUNTCASTLE, A.M.*; TULL, C.; DANIEL, T.L.; University of Washington mtcastle@u.washington.edu Many insects have wings that bend and twist during flight, often with dramatic deformations. The pattern and extent of deformation are dependent on wing flexural stiffness […]

Meeting Abstract 21.4  Sunday, Jan. 4  Scaling of passive damping and maneuverability in flying animals HEDRICK, TL*; DENG, X; CHENG, B; University of North Carolina at Chapel Hill; University of Delaware; University of Delaware thedrick@bio.unc.edu Most analyses of animal locomotion dynamics place stability and maneuverability on opposite poles; factors that enhance capability one are expected to reduce […]

Meeting Abstract 21.1  Sunday, Jan. 4  Probing insect flight stability and control by inducing aerial stumbles COHEN, I.*; RISTROPH, L. G.; BERMAN, G. J.; BERGOU, A. J.; WANG, Z. J.; Cornell University; Cornell University; Cornell University; Cornell University; Cornell University ic64@cornell.edu Flying insects are both marvelously stable and annoyingly evasive. Whether awe-inspiring or frustrating, flight must be […]
