Meeting Abstract 23.1  Jan. 5  Variation in entrainment of fictive swimming in lampreys due to bending stimuli at successive longitudinal positions TYTELL, E.D.*; COHEN, A.H.; University of Maryland; University of Maryland tytell@umd.edu In fishes, undulatory swimming is produced by sets of spinal interneurons constituting central pattern generators (CPGs). Coupling among successive oscillators in spinal cord produces in […]

Meeting Abstract 23.4  Jan. 5  Sucker-Arm Coordination in Octopus During Grasping and Manipulation of Objects GRASSO, Frank W.; Brooklyn College, the City University of New York fgrasso@brooklyn.cuny.edu In natural settings octopuses use their arms and suckers in a variety of dexterous manipulation tasks, such as extracting prey from crevices and burrows, opening bivalve shells and arranging middens […]

Meeting Abstract 23.2  Jan. 5  Integration of the pattern generation and multiple feedback pathways for the control of locomotion. A neuromusculoskeletal model. YAKOVENKO, Sergiy*; PROCHAZKA, Arthur; Universit� de Montr�al; University of Alberta sergiy.yakovenko@umontreal.ca Though not essential for the generation of locomotor activity, multiple sensory pathways participate in the locomotor control. In this study we investigated how stretch […]

Meeting Abstract 23.3  Jan. 5  In vivo activity of zebrafish inhibitory spinal interneurons across behaviours LIAO, James C.; Cornell University jl10@cornell.edu Inhibitory commissural spinal interneurons play a key role in shaping the rhythmicity underlying undulatory locomotion. Here we present data on the morphology, activity, and possible interconnectivity of these cell types in 2-5 day post-fertilization zebrafish larvae […]

Meeting Abstract 23.5  Jan. 5  Anterior cluster serotonergic neurons in the cerebropleural complex of Melibe leonina and their effects on other neurons MCPHERSON, D.R.; SUNY Geneseo mcpherso@geneseo.edu Like many other opisthobranch mollusc species, the nudibranch Melibe leonina has two bilaterally symmetrical clusters of serotonergic neurons in the anterior region of the cerebropleural complex of the central nervous […]

Meeting Abstract 22.5  Jan. 5  Reserve capacities of internal organs in laboratory mice divergently selected for basal metabolic rate (BMR) KSIAZEK, A.*; KONARZEWSKI, M.; CZERNIECKI, J.; University of Bialystok, Bialystok, Poland; University of Bialystok, Bialystok, Poland; University of Bialystok, Bialystok, Poland anetak@uwb.edu.pl BMR is considered to reflect energetic costs of maintenance of metabolically active internal organs. We […]

Meeting Abstract 22.3  Jan. 5  Phenotypic flexibility in cutaneous water loss and lipids of the stratum corneum in House sparrows (Passer domesticus) following acclimation to high and low humidity MU�OZ-GARCIA, Agust�*; COX, Robert M.; WILLIAMS, Joseph B.; Ohio State University; Ohio State University; Ohio State University munoz-garcia.1@osu.edu Resistance to water vapor diffusion through the skin is thought […]

Meeting Abstract 22.2  Jan. 5  Metabolic rate governs rates of genotypic and phenotypic evolution MCCOY, M. W.*; GILLOOLY, J. F.; ALLEN, A. P.; University of Florida; University of Florida; NCEAS mmccoy@zoo.ufl.edu Determining the relative importance of neutral versus adaptive processes in shaping rates of phenotypic evolution is a central aim of evolutionary biology. Many evolutionary biologists, while […]

Meeting Abstract 22.1  Jan. 5  Macro vs. Micro-Geographic Variation in Metabolism and Hormone Correlates in the Big Brown Bat ( Eptesicus fucus ) RICHARDSON, C.S.*; WIDMAIER, E.P.; MARSH, R.L.; KUNZ, T.H.; BOSTON UNIVERSITY; BOSTON UNIVERSITY; NORTHEASTERN UNIVERSITY, BOSTON; BOSTON UNIVERSITY crichard@bu.edu We examined basal metabolic rate (BMR) and plasma levels of thyroid hormone (T3) and leptin in […]

Meeting Abstract 22.4  Jan. 5  Effect of food restriction on ageing in laboratory mice (Mus musculus) selected for high and low basal metabolic rate (BMR) BRZEK, P.*; KSIAZEK, A.; KONARZEWSKI, M.; Univ Bialystok PL; Univ Bialystok PL; Univ Bialystok PL brzek@uwb.edu.pl The rate of aging is functionally related to the rate of metabolism. On the other hand, […]
