Meeting Abstract 39.4  Jan. 6  Affects of age and behavioral development on honey bee flight performance VANCE, JT*; WILLIAMS, JB; ELEKONICH, MM; ROBERTS, SP; Univ. of Nevada, Las Vegas jason.vance@unlv.edu During the transition from hive work to foraging, honey bees undergo numerous physiological changes, including a large increase in aerobic capacity, presumably to support the intense flight […]

Meeting Abstract 38.5  Jan. 5  Why do Africanized honey bees have higher metabolic capacities than Europeans? GRAYSON, Dina L.*; HARRISON, Jon F.; FEWELL, Jennifer H.; Arizona State University Dina.Grayson@asu.edu Africanized honey bees (AHB, Apis mellifera scutellata) are a highly successful invasive species that has spread throughout the neotropics by out-competing, hybridizing with, and replacing existing European honey […]

Meeting Abstract 38.3  Jan. 5  Ventilation is metabolically expensive in resting and running guinea fowl MARKLEY, J.S.*; CARRIER, D.R.; University of Utah; University of Utah markley@biology.utah.edu Avian ventilation may be metabolically costly because the mechanical work required to overcome the inertial and gravitational resistance to movement of the mass of the sternum, associated flight muscles, and viscera […]

Meeting Abstract 38.2  Jan. 5  Neutrons, Niches, and Adaptive Radiation in Cinclodes Ovenbirds MARTINEZ DEL RIO, C.*; SABAT, P.; Univ. of Wyoming; Univ. de Chile cmdelrio@uwyo.edu Passerines are astoundingly speciose and ecologically diverse. However, remarkably few songbird species have evolved a marine habit. The genus Cinclodes (Furnariidae) is an exception. In addition to species that inhabit terrestrial/freshwater […]

Meeting Abstract 38.1  Jan. 5  Faster with use: exercise affects turnover rate of carbon isotopes in some but not all organs MCWILLIAMS, S.R.*; BAUCHINGER, U.; KEIL, J.; STARCK, J.M.; University of Rhode Island; University of Munich; University of Munich; University of Munich srmcwilliams@uri.edu Most contemporary applications of stable isotopes in ecology and physiology rely on untested assumptions […]

Meeting Abstract 38.4  Jan. 5  Does body size affect the safety margin for oxygen delivery in flying dragonflies? HENRY, J.R.*; HARRISON, J.F.; Arizona State University; Arizona State University Joanna.Henry@asu.edu It has been widely hypothesized that the evolution of insect gigantism during the late Paleozoic was permitted due to increased atmospheric oxygen levels at the time. One mechanism […]

Meeting Abstract 38.6  Jan. 5  A climate-based model of winter energy consumption to examine the southern range limit of the goldenrod gall fly (Eurosta solidaginis) on late goldenrod (Solidago gigantea) IRWIN, J.T.*; DIDRICKSEN, D.J.; REILLY, B.W.; ABRAHAMSON, W.G.; Central Washington University, Ellensburg, WA; Central Washington University, Ellensburg, WA; Central Washington University, Ellensburg, WA; Bucknell University, Lewisburg, PA […]

Meeting Abstract 37.4  Jan. 5  Stress, stability and size: capturing process variation in the development of multicellular organisms BABBITT, G.A.; Arizona State University babbitts@gmail.com Definitions of developmental instability (DI) and its most common estimator, fluctuating asymmetry (FA), have often assumed that the variation in FA is caused by the organism�s ability to buffer additive effects of independent […]

Meeting Abstract 37.5  Jan. 5  Pond desiccation rate affects immune system responsiveness in a temporary pond breeding amphibian, the wood frog (Rana sylvatica) GERVASI, S.S.; University of Michigan sgervasi@umich.edu Theoretical studies and empirical data predict that life history strategies are often determined by variation in an organism�s environment. In response to environmental heterogeneity, many organisms have evolved […]

Meeting Abstract 37.3  Jan. 5  OXIDATIVE STRESS & INTESTINAL REMODELING DURING AMPHIBIAN METAMORPHOSIS: A BALANCING ACT! MENON, JAISHRI/G*; CHRIST, MICHELLE; GARDNER, EILEEN; William Paterson University; William Paterson University; William Paterson University menonj@wpunj.edu Anuran metamorphosis is characterized by extensive remodeling of the intestine which involves cell proliferation, apoptosis and cell differentiation. Involvement of reactive oxygen species (ROS) in […]
