Meeting Abstract 41.5  Wednesday, Jan. 5  Before and beyond congruence: using phylogenetic homology to infer evolutionary process BRAZEAU, MD; Museum fuer Naturkunde, Leibniz Institute for Research on Evolution and Biodiversity martin.brazeau@gmail.com The homology concept has garnered a reputation for being elusive and problematic. This view has grown in light of advances in modern comparative developmental genetics (‘evo-devo’). […]

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 […]

Meeting Abstract 40.1  Wednesday, Jan. 5  Creatine Kinase is Present in an Alveolate Protozoan HOFFMAN, GG; SUZUKI, T; ELLINGTON, WR*; Florida St. Univ., Tallahassee; Kochi Univ., Kochi, Japan; Florida St. Univ., Tallahassee wellington@admin.fsu.edu Creatine kinase (CK) is present in animals as a family of isoforms – cytoplasmic, mitochondrial and flagellar- each targeted to different intracellular compartments. Recently […]

Meeting Abstract 40.3  Wednesday, Jan. 5  Coevolution of morphology and locomotor performance in Urosaurus ornatus MILES, D B; Ohio University dmiles2@ohio.edu Species with widespread distributions often exhibit divergence in phenotypic traits. Such variation is attributed to selection imposed by local environmental conditions. Patterns in phenotypic traits that are associated with habitat or other ecological factors often are […]

Meeting Abstract 39.2  Wednesday, Jan. 5  Reconstructing growth of the basal archosauromorph Trilophosaurus WERNING, S*; IRMIS, RB; Univ of California, Berkeley; Univ of Utah; Utah Museum of Natural History swerning@berkeley.edu Despite extensive research on the evolution of bird-line archosaur growth strategies, the basal condition for archosaurian growth rates, bone histology, and ontogenetic changes in surface morphology remain […]

Meeting Abstract 39.5  Wednesday, Jan. 5  Mitochondria and aging: do duplicated mtDNA control regions confer longer lifespans in parrots? WRIGHT, T.F.*; SCHIRTZINGER, E.E.; YOUNG, A.M.; HOBSON, E.A.; EBERHARD, J.R.; New Mexico State University; New Mexico State University; New Mexico State University; New Mexico State University; Louisiana State University wright@nmsu.edu The mitochondrial theory of aging suggests that reactive […]

Meeting Abstract 39.3  Wednesday, Jan. 5  LIMITS ON BONE MOBILIZATION DURING REPRODUCTION HOOD, Wendy R; Auburn University wrhood@auburn.edu In iteroparous species, future reproductive capacity is dependent on an individual’s ability to retain sufficient body condition during prior bouts of reproduction to support survival and capacity to reproduce again. Mammalian mothers mobilize mineral from their own bone to […]
