Meeting Abstract S2.4  Tuesday, Jan. 4  Patterns of jaw-muscle recruitment evolution in mammals WILLIAMS, SH*; VINYARD, CJ; CROMPTON, AW; HYLANDER, WL; Ohio University, Athens; NEOUCOM, Rootstown; Harvard, Cambridge; Duke Univ., Durham willias7@ohio.edu The evolution and subsequent diversification of mammals is characterized by marked changes in the morphology of the masticatory apparatus, and these marked changes are presumably […]

Meeting Abstract S2.5  Tuesday, Jan. 4  Patterns of functional integration in the mammalian masticatory apparatus VINYARD, CJ*; DOHERTY, AH; WALL, CE; WILLIAMS, SH; ROSS, CF; HERRING, SW; CROMPTON, AW; HYLANDER, WL; NEOUCOM; NEOUCOM; Duke Univ; Ohio Univ; Univ of Chicago; Univ of Washington; Harvard Univ; Duke Univ cvinyard@neoucom.edu Jaw-muscle recruitment plays a key role in the complex […]

Meeting Abstract S2.6  Tuesday, Jan. 4  Masticatory motor patterns of herbivorous marsupials. CROMPTON, AW; WILLIAMS, SH*; Harvard Univ; Ohio Univ acrompton@oeb.harvard.edu Primitive masticatory motor patterns are characterized by the activation of a set of muscles (Group I) that move the working-side jaw laterally and vertically during occlusion followed by a comparable set (Group II) that move the […]

Meeting Abstract S2.9  Tuesday, Jan. 4  Mastication and the Postorbital Ligament: Dynamic Strain in Soft Tissues HERRING, S.W.*; RAFFERTY, K.L.; LIU, Z.J.; LEMME, M.; Univ. of Washington, Seattle herring@uw.edu Collagenous ligaments resist tension but are useless under other loading regimes. Whereas the periodontal and the jaw joint capsular ligaments are intrinsic parts of masticatory mechanics, this is […]

Ohio Univ. Col. of Med. and Pharm.; Univ. of Antwerp, Belgium druzinsk@uic.edu There is a deep and rich literature of comparative studies of jaw muscles in mammals (e.g., Toldt,1905; Edgeworth, 1935; Turnbull, […]

Meeting Abstract S2.1  Tuesday, Jan. 4  Introduction: Overview of the Feeding Experiments End-User Database (FEED) WALL, C.E.**; VINYARD, C.J.; WILLIAMS, S.H.; GERMAN, R.Z.; GAPEYEV, V.; LIU, X.; Duke Univ.; NEOUCOM; Ohio Univ.; Johns Hopkins Univ.; NESCent; NESCent cw19@duke.edu In 2009, we initiated a Working Group of feeding physiologists supported by the National Evolutionary Synthesis Center to develop […]

[…]

Meeting Abstract S2.3-2  Saturday, Jan. 4 14:00  The mechanisms of condition-dependent variation in melanin-based plumage color. D’ALBA, L.*; SPENCER, K.A.; VAN HEMERT, C.; HEIDINGER, B.J.; GILL, L.; EVANS, N.P.; MONAGHAN, P.; HANDEL, C.M.; SHAWKEY, M.D.; University of Akron; University of St. Andrews; USGS Alaska Science Center; University of Glasgow; Max Planck Institute for Ornithology; University of Glasgow; […]

Meeting Abstract S2.2-1  Saturday, Jan. 4 10:30  The evolution of honest communication: integrating social and physiological costs of ornamentation TIBBETTS, Elizabeth; University of Michigan tibbetts@umich.edu The honesty of animal communication systems is a central issue in behavioral and evolutionary biology. What prevents weak, low quality individuals from ‘cheating’ by signaling that they are strong? The general answer […]
