Effects of temperature on metabolic rates of Pacific bluefin tuna, Thunnus orientalis
BLANK, J.M.*; FARWELL, C.J.; MORRISSETTE, J.M.; SCHALLERT, R.J.; BLOCK, B.A.; Stanford University; Monterey Bay Aquarium; Stanford University; Monterey Bay Aquarium; Stanford University: Effects of temperature on metabolic rates of Pacific bluefin tuna, Thunnus orientalis Tunas are remarkable among teleosts for systemic endothermy, high metabolic rates and exceptional cardiac performance. Among tunas, the 3 bluefin species […]
Variation in entrainment of fictive swimming in lampreys due to bending stimuli at successive longitudinal positions
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 […]
Sucker-Arm Coordination in Octopus During Grasping and Manipulation of Objects
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 […]
Integration of the pattern generation and multiple feedback pathways for the control of locomotion A neuromusculoskeletal model
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 […]
In vivo activity of zebrafish inhibitory spinal interneurons across behaviours
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 […]
Anterior cluster serotonergic neurons in the cerebropleural complex of Melibe leonina and their effects on other neurons
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 […]
The Development of Muscle Biochemistry in a Diving Marine Endotherm, the Harbor Porpoise (Phocoena phocoena)
Meeting Abstract 23.5 Friday, Jan. 4 The Development of Muscle Biochemistry in a Diving Marine Endotherm, the Harbor Porpoise (Phocoena phocoena) NOREN, Dawn P.*; NOREN, Shawn R.; NOAA Fisheries, Northwest Fisheries Science Center; University of California, Santa Cruz dawn.noren@noaa.gov Skeletal muscles of marine mammals must support the metabolic demands of exercise during periods of reduced blood flow […]
Natural Neuroprotection in the Brains of Marine Mammals Why swimming dolphins dont stroke
Meeting Abstract 23.4 Friday, Jan. 4 Natural Neuroprotection in the Brains of Marine Mammals: Why swimming dolphins don�t stroke WILLIAMS, T.M.**; ZAVANELLI, M.; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz williams@biology.ucsc.edu Whereas neural impairment in human drowning victims can occur within a few minutes of submergence, extreme mammalian divers, most notably Weddell seals (Leptonychotes […]
Extreme starvation tolerance in snakes What makes them so different from other vertebrates
Meeting Abstract 23.3 Friday, Jan. 4 Extreme starvation tolerance in snakes. What makes them so different from other vertebrates? MCCUE, Marshall D; University of Arkansas mmccue@uark.edu Many snakes demonstrate the ability to survive periods of fasting that can last in excess of one year � a feat rarely matched by other vertebrates. Here I present the results […]
