Meeting Abstract 43.1  Saturday, Jan. 5  Anticipatory motor patterns limit muscle stretch during landing in toads AZIZI, E.*; ABBOTT, E.M.; Univ. of California, Irvine; Univ. of California, Irvine eazizi@uci.edu To safely land after a jump or hop, muscles must be actively stretched to dissipate mechanical energy. Muscles that dissipate energy can be damaged if stretched to long […]

R. ; Marshall University okeefef@marshall.edu The gray wolf, Canis lupus, exhibits both genetic and morphologic clinal variation across North America. While shape variation in wolf populations has been documented, no study has been […]

Meeting Abstract 43.5  Sunday, Jan. 5 11:15  Convergence in morphology and masticatory function between the pharyngeal jaws of grass carp and oral jaws of mammalian herbivores GIDMARK, NJ*; TARRANT, J; BRAINERD, EL; Brown University gidmark@uw.edu Herbivory is a mechanically difficult dietary specialization, as plant cell walls are chemically inert. In evolutionary shifts to herbivory, many amniotes (especially […]
