Meeting Abstract 40.6  Tuesday, Jan. 5  The unique pterosaur pteroid bone: wing function in extinct flying reptiles DYKE, Gareth*; PALMER, Colin; University College Dublin; University of Bristol gareth.dyke@ucd.ie Pterosaurs, flying reptiles from the Mesozoic, had wing membranes that were supported by the bones of their arm and a super-elongate fourth finger (the ‘wing-finger’). Associated with the wing, […]

Meeting Abstract 40.2  Tuesday, Jan. 5  Inference of diel activity pattern suggests complex temporal resource and habitat partitioning among Mesozoic archosaurs SCHMITZ, Lars*; MOTANI, Ryosuke; University of California, Davis; University of California, Davis lschmitz@ucdavis.edu Diel activity pattern (DAP) is an important behavioral characteristic of vertebrates that influences niche partitioning and resource use. Despite the complexity observed in […]

Meeting Abstract 40.4  Tuesday, Jan. 5  Evolution of locomotion and predation in saber-toothed cats ORCUTT, J.D.*; LEVERING, D.; DAVIS, E.B.; University of Oregon; Oklahoma State University; University of Oregon jorcutt@uoregon.edu An understanding of the ecological roles of organisms within paleocommunities is critical to tracking ecosystem change through time. For many extinct mammalian taxa, these roles can be […]

Meeting Abstract 40.1  Tuesday, Jan. 5  Does the Red Queen control the evolution of fossorial rodents in the Miocene of the southern Columbia Plateau? CALEDE, Jonathan JM*; HOPKINS, Samantha SB; University of Oregon; University of Oregon jcalede@uoregon.edu Several authors have proposed that the richness and species composition of the burrowing rodent guild was shaped by a series […]

Meeting Abstract 40.3  Tuesday, Jan. 5  Are extant cetaceans the product of an adaptive radation? SLATER, G.J.; PRICE, S.A.*; SANTINI, F.; ALFARO, M.E.; University of California, Los Angeles; University of California, Davis; University of California, Los Angeles; University of California, Los Angeles gslater@ucla.edu The transition from land to the sea represents a major shift in adaptive zone […]

Meeting Abstract 40.5  Tuesday, Jan. 5  Aquatic locomotion in fossil birds and early avian transitions from aquatic to terrestrial environments HINIC-FRLOG, S*; MOTANI, R; Carleton University, Ottawa; Univ. of California, Davis shinic@earthsci.carleton.ca Evolutionary transitions of secondarily aquatic organisms to terrestrial habitats are rare; however, birds represent a notable exception. A study of such transitions in birds requires […]

Meeting Abstract 40.2  Wednesday, Jan. 5  The evolution of acclimation of thermal performance CONDON, CH*; CHENOWETH, SF; WILSON, RS; The University of Queensland, Australia c.condon@uq.edu.au Many ectotherms have the capacity to alter the thermal dependence of a trait after a short period of acclimation to a new environment. Seasonal acclimation of performance traits in vertebrate ectotherms is […]

Meeting Abstract 40.6  Wednesday, Jan. 5  Sexual dimorphism of morphology and functional traits of the introduced Asian house gecko (Hemidactylus frenatus) across a latitudinal cline. CAMERON, SF*; ORTIZ-BARRIENTOS, D; WILSON, RW; The University of Queensland skyefc@hotmail.com Where different phenotypic optima exist between males and females of a species, sexual dimorphism is predicted to evolve. Although many studies […]

Meeting Abstract 40.5  Wednesday, Jan. 5  Phenotypic evolution of sexual dimorphism in hummingbird bills BERNS, Chelsea M.*; ADAMS, Dean C.; Iowa State University, Ames; Iowa State University, Ames cmberns@iastate.edu The ecological and evolutionary importance of sexual dimorphism in hummingbird bill morphology has been studied for over a century. Recent work has examined the functional relationship between bill […]

Meeting Abstract 40.4  Wednesday, Jan. 5  Microevolution of seasonal dimorphism in morphology and performance of a lizard IRSCHICK, Duncan J*; LANGERHANS, Brian; University of Massachusetts Amherst; North Carolina State University irschick@bio.umass.edu Dimorphisms are common in the animal kingdom, especially between males and females of the same species, but these also exist among males or females of the […]
