Meeting Abstract 48.5 Thursday, Jan. 5 Metabolic rates of an aquatic tardigrade, Dactylobiotus nuovo species. MEADE, Mark/E*; ROMANO, Frank; SEWELL, Susan; Jacksonville State University mmeade@jsu.edu We report here the use of a fiber optic, micro-respirometry system to monitor oxygen consumption rates in aquatic tardigrades. The system is highly sensitive (accuracy ±0.15% at 1% air saturation with a […]

Metabolic physiology of the stream minnow, Campostoma oligolepis, inhabiting a polluted stream
Meeting Abstract 48.6 Thursday, Jan. 5 Metabolic physiology of the stream minnow, Campostoma oligolepis, inhabiting a polluted stream. CORDLE, M.E.*; MEADE, M.E.; NICHOLS, A.; Jacksonville State University; Jacksonville State University; Jacksonville State University mecordle@gmail.com Snow creek, Oxford, Alabama, was a victim of industrial heavy metal and PCB contamination in the 1970s. In those years, high concentrations of […]
Do body composition drives winter variations of metabolic performance in black-capped chickadees (Poecile atricapillus)
Meeting Abstract 48.4 Thursday, Jan. 5 Do body composition drives winter variations of metabolic performance in black-capped chickadees (Poecile atricapillus)? PETIT, M*; VEZINA, F; Université du Québec à Rimouski; Université du Québec à Rimouski Magali.Petit@uqar.qc.ca Throughout the year, resident birds species living at northern latitudes exhibit changes in metabolic performance in response to seasonal variation in climatic […]
Comparative metabolic rate and assimilation between an endemic rattlesnake and an invasive boa implications for invasive species success
Meeting Abstract 48.3 Thursday, Jan. 5 Comparative metabolic rate and assimilation between an endemic rattlesnake and an invasive boa: implications for invasive species success GOESSLING, J.M.*; LUTTERSCHMIDT, W.I.; REINERT, H.K.; ODUM, R.A.; Sam Houston State University; Sam Houston State University and the Texas Research Institute for Environmental Studies; The College of New Jersey; Toledo Zoological Society goessling@auburn.edu […]
Are intraspecific correlations between minimum and maximum metabolic output in birds consistent with the aerobic capacity model for the evolution of endothermy
Meeting Abstract 48.1 Thursday, Jan. 5 Are intraspecific correlations between minimum and maximum metabolic output in birds consistent with the aerobic capacity model for the evolution of endothermy? SWANSON, David L*; THOMAS, Nathan E.; Univ. of South Dakota, Vermillion; Shippensburg Univ., Shippensburg, PA david.swanson@usd.edu The underlying assumption of the aerobic capacity model for the evolution of endothermy […]
A mechanism for metabolic scaling in insects
Meeting Abstract 48.2 Thursday, Jan. 5 A mechanism for metabolic scaling in insects CALLIER, V; Arizona State University vcallier@gmail.com In insect larvae, the tracheal system grows in discrete steps, increasing in size only at each molt. In contrast, the body increases in mass continuously, and metabolic demand increases in concert. This mode of growth makes insects particularly […]
The relationship between life history in temperate and tropical bird species and lipids in fibroblast mitochondrial membranes
Meeting Abstract 48.4 Saturday, Jan. 5 The relationship between life history in temperate and tropical bird species and lipids in fibroblast mitochondrial membranes CALHOON, E.A.*; JIMENEZ, A.G.; HARPER, J.M.; JURKOWITZ , M.S.; WILLIAMS, J.B.; Ohio State University; Ohio State University; University of Michigan; Ohio State University; Ohio State University calhoon.18@osu.edu Temperate birds are thought to have a […]
Physiological mechanisms of pleiotropy revealed by the accelerating effect of temperature
Meeting Abstract 48.1 Saturday, Jan. 5 Physiological mechanisms of pleiotropy revealed by the accelerating effect of temperature HOEKSTRA, LA*; SIDDIQ, M; MONTOOTH, KL; Indiana University lhoekstr@indiana.edu Organisms respond to environmental change with coordinated changes in metabolic processes. Plasticity in metabolic performance can create a dynamic context for the effects of mutations, particularly for mutations affecting energy use. […]
Molecular and biochemical observations of Mytilus californianus under constant submergence
Meeting Abstract 48.2 Saturday, Jan. 5 Molecular and biochemical observations of Mytilus californianus under constant submergence CONNOR, K.M.*; GRACEY, A.Y.; Univ. of California, Irvine; Univ. of Southern Califronia kwasiconnor@hotmail.com The mussel Mytilus californianus reside predominantly in the intertidal zone, a fluctuating environment at the interface of the terrestrial and marine biomes. However, cryptic populations have been found […]
