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, […]

Discontinuous respiration as a response to oxidative damage Tale of a sedentary insect
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 […]
Comparing heat loss and Osub2sub consumption rates in captive bottlenose dolphins (Tursiops truncatus)
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 […]
Calibration of heart rate and energy expenditure during flight and at rest in a passerine
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 […]
Biochemical stoichiometry affects whole-animal oxygen consumption rate in vivo
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 […]

C. ; Ewha Womans University; Smithsonian Tropical Research Institute; Ewha Womans University ocean74@snu.ac.kr Although the sensory trap model for sexually selected signals has been suggested over 2 decades, there has not yet been direct evidence […]
Long Term Performance Detriments In Songbirds With Extensive Carotenoid-Based Plumage Coloration Are Carotenoids Toxic
Meeting Abstract 64.5 Jan. 7 Long Term Performance Detriments In Songbirds With Extensive Carotenoid-Based Plumage Coloration: Are Carotenoids Toxic? HUGGINS, K.A.*; NAVARA, K.J.; HILL, G.E.; MENDONCA, M.T.; Auburn University; Ohio State University; Auburn University; Auburn University huggika@auburn.edu Although there is extensive literature addressing the beneficial effects of carotenoids as antioxidants and immune enhancers, there are also studies […]
Innovative Optics of Bright Wing Colors in Pierid Butterflies Morphological Determinants and Implications for Use as Visual Signals
Meeting Abstract 64.2 Jan. 7 Innovative Optics of Bright Wing Colors in Pierid Butterflies: Morphological Determinants and Implications for Use as Visual Signals MOREHOUSE, Nathan I.*; RUTOWSKI, Ronald L.; VUKUSIC, Peter; Arizona State University; Arizona State University; University of Exeter nmorehouse@asu.edu Animal color signals have been traditionally classified as either pigment based or structurally generated. However, little […]
Experimental manipulation of sexual selection and the evolution of locomotor performance in Drosophila pseudoobscura
Meeting Abstract 64.1 Jan. 7 Experimental manipulation of sexual selection and the evolution of locomotor performance in Drosophila pseudoobscura ROBERTS, SP*; CRUDGINGTON, HS; SNOOK, RR; Univ of Nevada Las Vegas; Univ of Sheffield; Univ of Sheffield stephen.roberts@unlv.edu Sexual selection typically yields sexual dimorphism in traits related to mate competition and mate choice, and among such traits in […]
A comparative analysis of natural and sexual selection in lizards
Meeting Abstract 64.4 Jan. 7 A comparative analysis of natural and sexual selection in lizards IRSCHICK, Duncan*; MEYERS, Jay; University of Massachusetts at Amherst; University of Massachusetts at Amherst irschick@bio.umass.edu The disparate forces of natural and sexual selection are often examined individually, and typically on single species. The downfall of this approach is that one cannot determine […]
