FRANZ-ODENDAAL, T.A.; Dalhousie University, Nova Scotia, Canada: Growth, development, constraint and variation of the skeletal elements within the teleost eye The sclera plays a supportive role in all vertebrate eyes and usually contains two skeletal elements. In bony fish (Teleostei) the scleral cartilage is restricted to an equatorial ring, unlike the situation in tetrapods. Some […]

CROLL, RP*; ROBERTSON, GN; MCGEE, CAS; SMITH, FM; Dalhousie Univ; Dalhousie Univ; Dalhousie Univ; Dalhousie Univ: Development of the swimbladder and its innervation in the zebrafish (Danio rerio) Gas-filled swimbladders play essential roles in buoyancy control of many teleosts, yet little is known of how these organs and their innervation develop to meet changing demands […]

JOST, JA*; HELMUTH, BST; University of South Carolina; University of South Carolina: Thermal tolerance of Geukensia demissa: The effect of daily maximum temperatures on growth and mortality Predicting alterations in communities due to climate change requires elucidation of both the physiological limits and the exposure ranges of organisms in the field. The Atlantic ribbed mussel, […]

DOWNS, C.J.**; HAYES, J.P.; TRACY, C.R.; University of Nevada, Reno; University of Nevada, Reno; University of Nevada, Reno: Temperature, Sampling Bias, and Scaling of BMR in Endotherms The basal metabolic rate (B) for an organism can be scaled to body mass (M) using the allometric equation, B = cMb, where i is the normalizing constant […]

SEPULVEDA , C. A.*; GRAHAM , J.B.; BERNAL, D.; Pfleger Institute of Environmental Research; Scripps Institution of Oceanography; University of Massachusetts, Dartmouth: Swimming performance studies of the mako shark, Isurus oxyrinchus The mako shark, Isurus oxyrinchus, is an active epipelagic predator that has been shown to possess several adaptations for a heightened aerobic swimming performance. […]

HERREL, A.*; JAMES, R.S.; VAN DAMME, R.; University of Antwerp, Belgium; Coventry University, UK; University of Antwerp, Belgium: Muscle physiology constrains behaviour in lizards: physiological basis for the fight vs. flight paradigm. Previous workers have noted that some agamid lizards show a temperature dependent behavioural shift where a flight response is used at high temperatures. […]

D. ; University of Florida, Gainesville; University of Florida, Gainesville; University of Arkansas, Fayetteville: Foraging and Water Requirement in Terrestrial Cottonmouth Snakes Cottonmouth snakes (Agkistrodon piscivorus conanti) inhabiting the Cedar Keys of Florida are terrestrial and dependent on condensation or rainfall for drinking water. Field […]

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 […]

SCHOECH, S.J.*; HAHN, T.P.; Univ. of Memphis; Univ. of California, Davis: Timing of reproduction and food supplementation: Are high latitude species less responsive than low latitude species to non-photic cues? Food supplementation usually advances the timing of egg laying in birds. A meta-analysis of 34 food supplementation studies suggests that high latitude species are less […]

MARTIN III, Arthur/L*; MOORE, Paul/A; Bowling Green State University; Bowling Green State University: The effects of shelter occupation on crayfish agonistic interactions Dominance provides access to resources such as mates, food, shelter, and other objects promoting survivorship and fitness (Wilson 1975). Shelters serve as a good source of protection from predators and conspecifics. The possession […]
