Meeting Abstract 9.2  Thursday, Jan. 3  Ventilation Mechanics in Resting and Swimming Spiny Dogfish DOLCE, J.*; WILGA, C.; Univ. of Rhode Island jdol6206@postoffice.uri.edu Oxygen consumption rates increase with swimming velocity in many fishes. As a result, ram ventilating fishes often enlarge the gape and opecular openings while swimming; however, modulation of suction ventilation mechanics during swimming has […]

Meeting Abstract 9.4  Thursday, Jan. 3  How do feathers produce aerodynamic sounds? Testing the ‘flag’ model CLARK, C. J.*; FEO, T. J.; UC Berkeley; UC Berkeley cclark@berkeley.edu Birds produce a variety of sounds with their feathers. Many of these sounds are aerodynamic, generated by air flowing over individual or combinations of feathers. Although often called whistles, Clark […]

[…]

Meeting Abstract 9.1  Thursday, Jan. 3  Examining the role of the amphibian and crocodilian “diaphragm” in aquatic locomotion URIONA, TJ*; FARMER, CG; Univ. of Utah, Salt Lake City; Univ. of Utah, Salt Lake City uriona@biology.utah.edu The convergent evolution of a crocodilian and an amphibian diaphragm suggests this muscle complex has an adaptive function in an aquatic environment. […]

Meeting Abstract 9.6  Thursday, Jan. 3  Elastic energy storage in a contracting poriferan? Quantitative imaging of morphological dynamics using synchrotron radiation based x-ray microtomography (SR-�CT) and in vivo-microradiography NICKEL, M; Institut fuer Spezielle Zoologie und Entwicklungsbiologie, FSU Jena, Germany Nickel@porifera.net The poriferan Tethya wilhelma is a model to investigate early evolved metazoan contractile tissues. The substantial contractions […]

Meeting Abstract 8.1  Thursday, Jan. 3  Strain environment, bone histomorphology, and growth in the emu femur and tibiotarsus MAIN, Russell P; Cornell University rpm74@cornell.edu A close relationship between skeletal form and mechanics has long been hypothesized. However, many studies have only examined these relationships in adult animals, while skeletal morphology is likely influenced by interactions between skeletal […]

Meeting Abstract 8.5  Thursday, Jan. 3  Skeletal Development of the Vertebral Column in the Miniature Hylid Frog Acris crepitans, with Comments on Vertebral Anomalies PUGENER, L.A.; MAGLIA, A.M.*; Missouri S&T, Rolla; Missouri S&T, Rolla magliaa@umr.edu Although the vertebral column of anurans has received much attention in the last 150 years, few detailed studies exist of their skeletal […]

Meeting Abstract 8.4  Thursday, Jan. 3  Postnatal development of the appendicular skeleton in mammals KILBOURNE, Brandon M.; University of Chicago, Chicago, IL bmkilbou@uchicago.edu Levels of perceived gracility and robustness are a conspicuous characteristic identifying some of the vast diversity within and between the major clades of mammals (�orders� of some authors). Though ontogenetic limb bone allometry has […]
