Meeting Abstract 102.6  Saturday, Jan. 7  Are the plastral scutes and plastral lobes of turtle shells modules? A geometric morphometric perspective ANGIELCZYK, K. D.*; MELSTROM, K. M.; Field Museum of Natural History; Univ. of Michigan kangielczyk@fieldmuseum.org The turtle plastron (ventral shell) is covered by a series of keratinous scutes. Each scute is derived from one tissue condensation; […]

Meeting Abstract 102.4  Sunday, Jan. 6  Scaling of the ctenidium in juvenile suspension feeding bivalves PERINO, L..L.; PADILLA, D.K.*; Stony Brook University; Stony Brook University dianna.padilla@stonybrook.edu The ctenidium, or gill, of suspension-feeding bivalves has two major functions. It is a respiratory organ, but is it also the primary organ used for feeding. Cilia on the ctenidium form […]

Meeting Abstract 102.2  Sunday, Jan. 6  Scaling of the Hydrostatic Skeleton in the Earthworm, Lumbricus terrestris KURTH, J.A.*; KIER, W.M.; University of North Carolina, Chapel Hill; University of North Carolina, Chapel Hill jkurth@live.unc.edu The structural and functional consequences of changes in size or scale have been well studied in animals with rigid skeletons, but relatively little is […]

Meeting Abstract 102.6  Sunday, Jan. 6  Scaling of radular length and replacement rate in the Atlantic slippersnail, Crepidula fornicata. PADILLA, D.K.*; YEE, A.; Stony Brook University; Stony Brook University padilla@life.bio.sunysb.edu All organisms undergo changes in size during ontogeny, and, for multicellular animals, morphologies, behavior and performance frequently do not scale simply with size. In addition, throughout ontogeny […]

Meeting Abstract 102.3  Sunday, Jan. 6  Scale effects and rotational inertia in the limbs of quadrupedal mammals KILBOURNE, B.M.; University of Chicago brandon.kilbourne@uni-jena.de Recent biomechanical studies have revealed that the metabolic cost of swinging the limbs is a significant portion of the total metabolic cost of terrestrial locomotion. Such studies suggest that limb rotational inertia, which reflects […]

Meeting Abstract 102.5  Sunday, Jan. 6  Effects of scaling on bite force and suction index in the Eastern Hellbender (Cryptobranchus alleganiensis) LARGHI, N.P.*; DEBAN, S.M.; Univ. of South Florida, Tampa; Univ. of South Florida, Tampa nlarghi@gmail.com In 1950, AV Hill developed a series of predictions on how animal movements should scale with body size. Since this pivotal […]

Meeting Abstract 102.7  Tuesday, Jan. 7 09:30  Thermoregulation and energetics in hibernating black bears: The mystery of multi-day body temperature cycles. BARNES, BM*; TOIEN, O; Univ of Alaska Fairbanks bmbarnes@alaska.edu Black bears overwintering in outdoor hibernacula in Fairbanks, Alaska don’t move much, reduce whole body metabolism to as low as 25% of basal rates, and decrease core […]
