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 19.1  Sunday, Jan. 4 10:15  Ultrafast weapons in mantis shrimp: winners of fights strike more frequently, not with greater force GREEN, P.A.*; PATEK, S.N.; Duke University; Duke University patrick.a.green@duke.edu The extreme impact forces and dramatic displays delivered by fighting mantis shrimp (Stomatopoda) are an exceptionally dynamic example of weapon use. While knowledge of weapon systems […]

Meeting Abstract 19.4  Sunday, Jan. 4 11:00  The social adrenal: Evidence for a seasonal switch from gonadal to adrenal regulation of aggression in female Siberian hamsters (Phodopus sungorus) RENDON, N.M.*; RUDOLPH, L.M.; SENGELAUB, D.R.; DEMAS, G.E.; Indiana University Bloomington nrendon@indiana.edu Appropriate levels of aggression can ensure acquisition of territory and mates during the breeding season and acquisition […]

Meeting Abstract 19.6  Sunday, Jan. 4 11:30  Kin Recognition in an Asexual Fish, Poecilia formosa MAKOWICZ, A*; SCHLUPP, I; University of Oklahoma; University of Oklahoma amber_makowicz@ou.edu Kin selection theory states that individuals should favor their kin at the cost of their own fitness when the benefits of inclusive fitness outweigh the costs. In clonal species, relatedness is […]

Meeting Abstract 19.7  Sunday, Jan. 4 11:45  Genomic Relatedness Predicts Investment in a Public Good LEIGHTON, GM; University of Miami gleighton@bio.miami.edu Although communal resources, i.e. public goods, are often critical to society, they are simultaneously susceptible to exploitation, and are evolutionarily stable only if mechanisms exist to curtail exploitation. Mechanisms such as punishment and kin selection have […]
