The Diversity and Evolution of Jumping Power in Anurans
Meeting Abstract 42-2 Saturday, Jan. 5 08:15 – 08:30 The Diversity and Evolution of Jumping Power in Anurans MENDOZA, E*; AZIZI, E; MOEN, DS; Oklahoma State University; University of California, Irvine; Oklahoma State University emendoz7@uci.edu Jumping in anurans requires substantial mechanical power. However, while muscle power appears to be relatively invariant across species, jumping power is […]
Mechanical Cost Dynamics of Single and Double Stance in Human Walking
Meeting Abstract 42-1 Saturday, Jan. 5 08:00 – 08:15 Mechanical Cost Dynamics of Single and Double Stance in Human Walking ISAACS, MR*; LEE, DV; University of Nevada, Las Vegas; University of Nevada, Las Vegas michael.isaacs@unlv.edu Conventionally, all or nearly all of the mechanical cost of bipedal walking is assumed to be incurred during the step-to-step transition, whereas […]
Experimental Studies of Power, Moments and Energetics in Flapping, Flexible Insect Wings
Meeting Abstract 42-5 Saturday, Jan. 5 09:00 – 09:15 Experimental Studies of Power, Moments and Energetics in Flapping, Flexible Insect Wings JANKAUSKI, MA; Montana State University mark.jankauski@montana.edu http://www.mjankauski.com Flapping insect wings bend and deform during flight. Recent evidence suggests this deformation improves power economy and reduces the cost of locomotion. To assess this hypothesis, we drive a […]

Deadly Jaws Functional Morphology and Strike Kinematics of Acanthognathus Trap-Jaw Ants
Meeting Abstract 42-3 Saturday, Jan. 5 08:30 – 08:45 Deadly Jaws: Functional Morphology and Strike Kinematics of Acanthognathus Trap-Jaw Ants GIBSON, J. C.*; SUAREZ, A. V.; University of Illinois at Urbana-Champaign; University of Illinois at Urbana-Champaign jcgibso2@illinois.edu High speed power-amplification mechanisms have evolved independently in many groups of organisms across the tree of life, including multiple times […]
