MALOIY, G.M.O.; RUGANGAZI, B.M.; ROWE*, M.F.; Institute of Animal Physiology and Biotechnology Research, Nairobi; Institute of Animal Physiology and Biotechnology Research, Nairobi; University of New Orleans: Heart Rate and Energy Expenditure at Rest and Exercise in the Domestic Donkey and One Humped Camel Both the domestic donkey and one-humped camel are of great economic value […]

MOORE, Ignacio T.; BONIER, Frances; WINGFIELD, John C.; University of Washington; same; same: Gene flow between two equatorial populations of rufous-collared sparrows, Zonotrichia capensis, with opposed reproductive patterns Seasonally breeding birds in northern latitudes are typically photoperiodic and use changes in daylength to time reproduction. The environmental cues used for timing of seasonal reproduction have […]

HENRY, R.P.*; SMITH, C.; Auburn Univ.; Unov. of New Hampshire: Functional characteristics of a carbonic anhydrase repressor in the eyestalk of the euryhaline green crab, Carcinus maenas. The enzyme carbonic anhydrase (CA) is induced 8-12 fold in the posterior, ion transporting gills of euryhaline crustaceans during low salinity acclimation. In the green crab, there is […]

MOON, B. R.; Univ. Louisiana, Lafayette: From physiology to fitness: low-impact aerobics in rattlesnakes Specialized features may incur costs to organisms that may reduce fitness by diverting energy away from reproduction. However, the energetic and fitness costs of having and using specialized features are rarely measured. The specialized shaker muscles of rattlesnakes are an excellent […]

GABALDON, Annette/M; NELSON, Frank/E; ROBERTS, Thomas/J; Oregon State Univ., Corvallis OR; Oregon State Univ., Corvallis OR; Oregon State Univ., Corvallis OR: Force-Velocity Characteristics of Ankle Extensor Muscles in Wild Turkeys During Running and In Situ Muscles develop their highest power outputs at intermediate relative shortening velocities, i.e., approximately 0.30 V/Vmax, and near-maximal forces at V/Vmax […]

BUFFENSTEIN, Rochelle; SALTON, Justine; City University of New York; City University of New York: Field thermoregulatory profiles in tenrecs from the rainforest and dryforest of Madagascar Although the Tenrecidae is as an ancient eutherian lineage, with more than 26 species living in a diverse range of habitats. We asked if closely-related tenrecids from the arid […]

KLEE, V.; WEINSTEIN, R.B.; Univ. of Arizona, Tucson: Fatiguing stimulation of ghost crab extensor carpopodite is not accompanied by an accumulation of inorganic phosphate in muscle homogenates Ghost crabs exercising at a speed faster than their maximum aerobic speed (MAS) fatigue within several minutes. We examined whether high intensity stimulation of the extensor capopodite, an […]

GOLDBOGEN, Jeremy; SHADWICK, Robert; Scripps Institution of Oceanography, University of California – San Diego; Scripps Institution of Oceanography, University of California – San Diego: Fast-start muscle dynamics in the rainbow trout Oncorhynchus mykiss. Recent investigations regarding the muscle dynamics of fish locomotion have provided evidence that the wave of muscle shortening traveling along the body […]
