Meeting Abstract 90.1  Wednesday, Jan. 7  Ontogeny of locomotor performance in a ground bird JACKSON, B.E.*; DIAL, K.P.; Univ. of Montana; Univ. of Montana brandon.jackson@mso.umt.edu Due to post-natal predation pressure many juvenile animals face a developmental tradeoff between escape ability and investment in other systems. In birds these tradeoffs are unique because birds transition through hindlimb- to […]

Meeting Abstract 90.3  Wednesday, Jan. 7  Ontogenetic convergence in ventral skull shape between males and females of a sexually dimorphic antelope BRAKORA, Katherine*; KHUC, Kim; University of California, Berkeley kbrakora@berkeley.edu Although antelope provide many classic examples of sexual dimorphism among mammals, their morphology has not been systematically quantified in terms of sexual differences in size, shape or […]

Meeting Abstract 90.7  Wednesday, Jan. 7  ONTOGENETIC ALLOMETRY OF LONG BONES IN MAMMALS AND DINOSAURS AND ITS USE AS A PREDICTOR OF LIFE HISTORY TRAITS KILBOURNE, BM; University of Chicago bmkilbou@uchicago.edu In addition to providing insight into the ontogenetic development of the locomotor system, ontogenetic limb bone allometry may reflect other aspects of an organism’s life history, […]

Meeting Abstract 90.8  Wednesday, Jan. 7  Non-invasive histological comparison of bone growth patterns among fossil and extant neonatal elephantids using synchrotron radiation X-ray microtomography CURTIN, A.J.*; MACDOWELL, A.A.; SCHAIBLE, E.G.; ROTH, V.L.; Duke Univ.; Advanced Light Source, Lawrence Berkeley National Lab.; Advanced Light Source, Lawrence Berkeley National Lab.; Duke Univ. amanda.curtin@duke.edu How is bone growth modified in […]

Meeting Abstract 90.9  Wednesday, Jan. 7  Effects of exercise on skeletal growth and bone microstructure of the American alligator with and without the cardiac shunt OWERKOWICZ, T.*; TSAI, H.P.; BLANK, J.M.; EME, J.; GWALTHNEY, J.W.; HICKS, J.W.; UC Irvine; UC Irvine; UC Irvine; UC Irvine; UC Irvine; UC Irvine towerkow@uci.edu Exercise can affect the vertebrate skeleton via […]

Meeting Abstract 90.4  Wednesday, Jan. 7  Development of a functional complex: Ontogeny of the zebrafish pharyngeal jaw apparatus O’QUIN, C.T.*; HERNANDEZ, L.P.; The George Washington University; The George Washington University ctoquin@gwu.edu The pharyngeal jaw apparatus of teleosts has long been of interest to both functional and descriptive morphologists alike. However, little to no work has been done […]

Meeting Abstract 89.5  Wednesday, Jan. 7  Trade-off between maternal immunocompetence and offspring viability in zebra finches RUTKOWSKA, Joanna*; MARTYKA , Rafal; CICHON, Mariusz; Institute of Environmental Sciences, Jagiellonian University joanna.rutkowska@uj.edu.pl The immune system is an important player in individual physiological trade-offs; however, intergenerational effects of immunocomeptence have rarely been explored. Immunocompetent mothers should produce high quality offspring, […]

Meeting Abstract 89.3  Wednesday, Jan. 7  The cost of bearing a sword: an examination of the locomotor costs associated with a sexually selected trait in Xiphophorus. OUFIERO, Christopher E.*; GARLAND, JR., Theodore; Univ. of California, Riverside coufi001@student.ucr.edu An underlying assumption of sexual selection theory is that while the secondary traits that arise increase reproductive fitness, they also […]

Meeting Abstract 89.6  Wednesday, Jan. 7  Greater Ranging Associated with Greater Reproductive Investment in Mammals: A New Perspective on Foraging Economics PONTZER, Herman*; KAMILAR, Jason; Washington Univ.; Washington Univ. hpontzer@artsci.wustl.edu Animals must travel to find food, incurring an energy and time cost. Both modeling studies and experimental work indicate that within species, increasing the distance traveled each […]

Meeting Abstract 89.2  Wednesday, Jan. 7  Evolutionary origins and functions of nuptial gifts in fireflies SOUTH, Adam*; STANGER-HALL, Kathrin; LEWIS, Sara M. ; Tufts University; University of Georgia; Tufts University adam.south@tufts.edu During courtship and mating in diverse insect taxa, males provide females with nuptial gifts in the form of captured prey, spermatophores, or body parts. Such nuptial […]
