Meeting Abstract 65.9  Jan. 7  Effects of Experimental Erythropoietin Elevation on Voluntary Exercise and Maximal Aerobic Capacity in House Mice KOLB, EM*; KELLY, SA; MIDDLETON, KM; SERMSAKDI, LS; GARLAND, JR., T; Univ. of California, Riverside zookolb@yahoo.com Voluntary exercise is a complex trait involving numerous subordinate characters, both behavioral and physiological. We have used artificial selection for voluntary […]

Meeting Abstract 65.11  Jan. 7  Effect of high CO2 on the metabolism of jumbo squid Dosidicus gigas ROSA, R/A*; SEIBEL, B/A; University of Rhode Island; University of Rhode Island rrosa@etal.uri.edu The absorption of atmospheric CO2 causes ocean acidification, i.e., decreasing pH. Since the effects of environmentally relevant pH reduction on the marine biota are still poorly understood, […]

Meeting Abstract 65.5  Jan. 7  Discontinuous respiration as a response to oxidative damage: Tale of a sedentary insect CONTRERAS, H.L.*; BRADLEY, T.J.; Univ. of California, Irvine hcontrer@uci.edu Insects have a relatively high mass-specific metabolic rate due their small size. It is surprising, therefore, that numerous taxa exhibit the discontinuous gas exchange cycle (DGC), a respiratory pattern in […]

Meeting Abstract 65.4  Jan. 7  Comparing heat loss and O2 consumption rates in captive bottlenose dolphins (Tursiops truncatus) MEAGHER, E/M*; MCLELLAN, W/A; WILLIAMS, T/M; BLUM, J/E; PABST, D/A; UNC Wilmington; UNC Wilmington; UC Santa Cruz; UNC Wilmington; UNC Wilmington emm3005@uncw.edu Measurements of heat loss have been used to estimate marine mammal metabolic rate (MR), but few studies […]

Meeting Abstract 65.10  Jan. 7  Calibration of heart rate and energy expenditure during flight and at rest in a passerine BOWLIN, M.S.*; WIKELSKI, M.C.; Princeton University; Princeton University mbowlin@princeton.edu Previous calibrations between heart rate and energy expenditure measured using either doubly labeled water or respirometry have shown that in large birds, for a given species and activity […]

Meeting Abstract 65.6  Jan. 7  Biochemical stoichiometry affects whole-animal oxygen consumption rate in vivo WELCH, KC*; SUAREZ, RK; Univ. of California, Santa Barbara; Univ. of California, Santa Barbara k_welch@lifesci.ucsb.edu The stoichiometric relationship of molecular oxygen consumption to ATP production is known to vary as a function of the metabolic substrate used. The P/O ratio of isolated mitochondria […]

Meeting Abstract 65.6  Sunday, Jan. 6  The evolutionary history of little squeakers with big fingers: a frog perspective on diversity and evolution across sub-Saharan Africa BLACKBURN, D.C.; Harvard University dblackb@fas.harvard.edu Patterns of and the historical processes underlying biological diversity in sub-Saharan Africa are still both poorly documented and understudied. This study focuses on squeakers and long-fingered frogs, […]

Meeting Abstract 65.5  Sunday, Jan. 6  Systematic position of Thalassianthidae among sea anemones using mitochondrial and nuclear genes. CROWTHER, A.L.*; DALY, M.; FAUTIN, D.G.; Univ. of Kansas, Lawrence; Ohio State Univ., Columbus; Univ. of Kansas, Lawrence andreac@ku.edu We infer from morphological data that sea anemones of the family Thalassianthidae form a monophyletic group: all species possess both […]

Meeting Abstract 65.4  Sunday, Jan. 6  Sibling Sea Urchin Species of the Genus Echinothrix in Hawai’i: Morphology, Genetics, & Ecology JESSOP, H.*; LESSIOS, H.A.; DEMAINTENON, M.J.; TAKABAYASHI, M.; University of Hawai’i at Hilo; Smithsonian Tropical Research Institute; University of Hawai’i at Hilo; University of Hawai’i at Hilo hollyjessop@yahoo.com Sympatric sibling species have the potential to be especially […]

Meeting Abstract 65.3  Sunday, Jan. 6  Sexual maturity in subadult dinosaurs does not fit reptilian growth models LEE, A.H.*; WERNING, S.; Ohio University, College of Osteopathic Medicine; Univ. of California, Berkeley lee@oucom.ohiou.edu Age at reproductive maturity (RM) is largely unknown in extinct taxa because unambiguous indicators of RM are rare. One exception is medullary bone (MB), which […]
