Meeting Abstract 32.2  Friday, Jan. 4  Forelimb muscle activity in swimming sliders and sea turtles: are muscle activation patterns conserved? RIVERA, A.R.V.*; WYNEKEN, J.; BLOB, R.W.; Clemson Univ; Florida Atlantic Univ; Clemson Univ arivera@clemson.edu Tetrapod limbs have been modified numerous times through evolution to yield a diverse array of forms. New locomotor behaviors might arise through evolutionary […]

Meeting Abstract 32.3  Friday, Jan. 4  Allometry of maximal muscular power output in corvids JACKSON, B.E.; Univ. of Montana, Missoula brandon.jackson@mso.umt.edu Body size has observable influences on virtually all aspects of animal biology, yet we lack detailed understanding of the physical mechanisms underlying many of these patterns. In an effort to examine the allometry of locomotor performance […]
