Meeting Abstract 19.1  Saturday, Jan. 4 10:15  The radiation of a living fossil: Jaw morphology of tree squirrels ZELDITCH, M.L*; LI, J.; TRAN, L.A.P.; SWIDERSKI, D.L.; Univ. of Michigan, Ann Arbor zelditch@umich.edu The dynamics of adaptive radiations have captured much attention recently, but equally interesting are groups famed for their morphological conservatism, i.e., living fossils. Some living […]

Meeting Abstract 19.6  Saturday, Jan. 4 11:30  Olfactory Evidence on the Terrestrial Origins of Monotremata SIMON, R.V.*; ROWE, T.B.; The University of Texas at Austin; The University of Texas at Austin rvsimon@utexas.edu Whether Monotremata originated as a terrestrial or aquatic clade is a hot debate that so far has revolved around the interpretation of fragmentary Early Cretaceous […]

Meeting Abstract 19.4  Saturday, Jan. 4 11:00  Macroevolutionary relationships between size and diet in mammals. PRICE, S. A.*; HOPKINS, S.S.; Univ. of California, Davis; Univ. of Oregon saprice@ucdavis.edu Living mammals exhibit remarkable variability in body mass, spanning eight orders of magnitude from the bumblebee bat (~1.3g) to the blue whale (~160 tonnes). Due to the high energy […]

Meeting Abstract 19.3  Saturday, Jan. 4 10:45  Macroevolutionary dynamics of scapula shape and locomotor behavior in Carnivora SLATER, GJ; Smithsonian Institution SlaterG@si.edu The mammalian scapula is a large, flat bone, forming the proximal end of the forelimb. Because the scapula has no bony articulation with the axial skeleton, the forelimb attaches to and supports the trunk through […]

Meeting Abstract 19.2  Saturday, Jan. 4 10:30  A comparison of two radiations: Jaw morphology of terrestrial squirrels SWIDERSKI, D.L.*; LI, J.; TRAN, L.A.P.; ZELDITCH, M.L.; Univ. of Michigan, Ann Arbor dlswider@umich.edu The dynamics of adaptive radiations have captured much attention recently, but equally interesting are groups famed for their morphological conservatism, particularly those that are speciose and […]

Meeting Abstract 19.5  Saturday, Jan. 4 11:15  50 Million Years of Severe Osteopathology in Rhinocerotidae STILSON, K/T*; HOPKINS, S/S/B; DAVIS, E/B; University of Texas at Austin; University of Oregon; University of Oregon stilson@utexas.edu Skeletal pathologies in the fossil record are commonly considered indicators of an individual animal’s life history and development, and not reflections of processes related […]

Meeting Abstract 18.7  Saturday, Jan. 4 11:45  Vibrating Bees: Behavioral Changes in Buzz Frequency SWITZER, C.S.*; COMBES, S.A.; Harvard Univ., Cambridge; Harvard Univ., Cambridge cswitzer@fas.harvard.edu Multiple bee taxa have evolved the ability to collect pollen by shaking it from plants’ anthers. While grasping or touching the anthers, bees vibrate their bodies using their flight muscles, without flapping […]

Meeting Abstract 18.4  Saturday, Jan. 4 11:00  Using a Hidden Markov Model to find foraging areas for the gray smooth-hound shark (Mustelus californicus) in a Full Tidal Basin NEEMAN, N*; ESPINOZA, M; FARRUGIA, TJ; LOWE, CG; SOBEL, MJ; O’CONNOR, MP; Drexel University; California State University, Long Beach; California State University, Long Beach; California State University, Long Beach; […]

Meeting Abstract 18.2  Saturday, Jan. 4 10:30  Migratory Predators Adjust Foraging Behavior in Response to Migratory Prey KRAUEL, J.J.*; MCCRACKEN, G.F.; Univ. of Tennessee, Knoxville; Univ.of Tennessee, Knoxville jkrauel@utk.edu Little is known about interactions between migratory predators and migratory prey, although these systems may be at high risk to disruption due to habitat loss and climate change. […]

Meeting Abstract 18.6  Saturday, Jan. 4 11:30  Locomotor performance of lizards during pursuit of prey and evasion from predators ANDERSON, R A; Western Washington Univ. Roger.Anderson@wwu.edu A robust, comprehensive study of locomotory capabilities in a terrestrial vertebrate requires adequate observation and testing in the field as well as in the lab. Terrestrial lizards in desert scrub are […]
