Meeting Abstract 99-2  Saturday, Jan. 7 13:45 – 14:00  Methods for Combining Multiple Multivariate Performance Surfaces to Explain Patterns of Phenotypic Diversification STAYTON, CT; Bucknell University tstayton@bucknell.edu Performances surfaces are representations of the relationship between phenotype and performance in a particular function. They are often employed to explore patterns of phenotypic diversification. However, many structures perform multiple […]

Meeting Abstract 99-6  Saturday, Jan. 7 14:45 – 15:00  Functional Redundancy Permits Morphological Differences Between Frog Ecomorphs Without Reducing Performance MOEN, DS*; HANSON, DK; Oklahoma State University; Oklahoma State University daniel.moen@okstate.edu http://www.dsmoen.com Why do organisms with similar ecologies often have similar morphology? Evolution of morphology usually results from selection on functional performance, so to answer this question […]

Meeting Abstract 98-6  Saturday, Jan. 7 14:45 – 15:00  Variable Limb Function Results in Similar Turning Behavior in Lizards. LIBBY, T*; FULL, R.J.; Univ. of California, Berkeley tlibby@berkeley.edu Periodic steady-state locomotion like flat-ground walking and running typically display high stereotypy of forces and kinematics during limit-cycle behavior. We examined variability in an unsteady maneuver in lizards, Agama […]

Meeting Abstract 98-8  Saturday, Jan. 7 15:15 – 15:30  Spiders “limp” to achieve a more stable gait HSIEH, ST*; SHAMBLE, P; WILSHIN, S; HOVEY, K; SPENCE, AJ; Temple University; Harvard University; Royal Veterinary College; Temple University; Temple University sthsieh@temple.edu http://astro.temple.edu/~sthsieh/ Many invertebrates are capable of voluntarily losing limbs (autotomy) in response to antagonistic encounters. How they rapidly […]

Meeting Abstract 98-3  Saturday, Jan. 7 14:00 – 14:15  Side-Impact Collision: Obstacle Negotiation Mechanics in Sidewinding Snakes ASTLEY, H.C.*; MENDELSON, J.R.; GOLDMAN, D.I.; University of Akron; Zoo Atlanta; Georgia Institute of Technology hastley@uakron.edu http://gozips.uakron.edu/~hastley/ Snakes display several locomotor modes which allow them to overcome a wide range of terrain challenges. Sidewinding is a mode which allows snakes […]

Meeting Abstract 98-4  Saturday, Jan. 7 14:15 – 14:30  Leg vibrations help cockroaches self-right using wings OTHAYOTH, RS*; XUAN, QH; LI, C; Johns Hopkins University ratan@jhu.edu http://li.me.jhu.edu/ When flipped over, cockroaches can use their wings to push against the ground to self-right dynamically. In this process, it often takes an animal multiple failed maneuvers before it eventually […]
