Meeting Abstract 51.5  Tuesday, Jan. 5  Reproductive aging in Siberian hamsters: greater litter success in older females when short photoperiod is initiated after rather than before puberty PLACE, N.J.**; CRUICKSHANK, J.; Cornell University, Ithaca njp27@cornell.edu Fertility and fecundity decline with age in female mammals, and in Siberian hamsters, Phodopus sungorus, litter success rate was markedly lower in […]

Meeting Abstract 51.3  Tuesday, Jan. 5  Energy, growth and oxidative stress in Leach’s storm-petrels (Oceanodroma leucorhoa) HAUSSMANN, M.F.*; MAUCK, R.A.; Bucknell Univ, Lewisburg, PA; Kenyon College, Gambier, OH mfh008@bucknell.edu Limitation in energy allocation is the main force underlying life history trade-offs. Aerobic species have evolved the capability to use oxygen for efficient energy release. A consequence of […]

Meeting Abstract 51.4  Tuesday, Jan. 5  Dietary n-3 and n-6 polyunsaturated fatty acid supplementation alters heart phospholipid composition but does not affect lifespan VALENCAK, TG*; RUF, T; University of Veterinary Medicine Vienna; University of Veterinary Medicine Vienna teresa.valencak@vetmeduni.ac.at Smaller mammals such as mice possess tissues containing more polyunsaturated fatty acids (PUFAs) while at the same time living […]

Meeting Abstract 50.2  Tuesday, Jan. 5  The head-down posture of seahorses: an adaptation for pivot feeding? VAN WASSENBERGH, S.*; ROOS, G.; AERTS, P.; Univ. Antwerpen, Antwerpen; Univ. Antwerpen, Antwerpen; Univ. Antwerpen, Antwerpen sam.vanwassenbergh@ua.ac.be Syngnathid fishes capture prey by rotating their head quickly towards prey, and subsequently sucking it into their snout. Previous studies showed that head pivoting […]

Southern Maine; Univ. California, Los Angeles; Aust. Nat. Univ. walker@maine.edu The repeated evolution of streamlined body shapes among large, fast aquatic animals is a textbook example of evolutionary convergence. The oft-cited […]

Meeting Abstract 50.3  Tuesday, Jan. 5  Comparative Evolutionary Dynamics in Cichlid Adaptive Radiations: Linking Lower Jaw Genetics, Morphology, and Mechanics HULSEY, CD*; STREELMAN, JT; Univ. of Tennessee; Georgia Institute of Technology chulsey@utk.edu The lower jaw is a major determinant of feeding diversification in cichlid adaptive radiations. It also provides an ideal phenotype to compare rates and patterns […]

Meeting Abstract 49.4  Tuesday, Jan. 5  The ontogeny of feeding systems in caecilians (Lissamphibia: Gymnophiona) – sucking, scraping, and biting KLEINTEICH, T; University of Hamburg thomas.kleinteich@uni-hamburg.de The caecilian feeding system is unique among vertebrates in that two jaw closing mechanisms are integrated: jaw closure is driven by the ancestral jaw closing muscles (mm. levatores mandibulae) plus a […]

Meeting Abstract 49.3  Tuesday, Jan. 5  Labial tooth number affects feeding kinematics in a ranid tadpole VENESKY, Matthew*; WASSERSUG, Richard; PARRIS, Matthew; Univ. of Memphis; Dalhousie Univ.; Univ. of Memphis mvenesky@memphis.edu We used high-speed videography to explore how missing labial teeth alters the feeding kinematics and foraging performance of Southern Leopard Frog (Lithobates sphenocephalus) tadpoles. In Experiment […]
