REILLY, Stephen M.; BIKNEVICIUS, Audrone R.; Ohio University; Ohio University: Integrating mechanics and kinematic gaits in tetrapod locomotion: congruence and variation in “walking” and “running” Two descriptive paradigms have emerged from studies of terrestrial vertebrate locomotion: kinematic patterns of footfalls are used to describe the gaits used by animals and kinetic patterns are used to […]

HSIEH, S.T.; Harvard University: Fish out of water: the amphibious locomotor repertoire of the Pacific leaping blenny, Alticus arnoldorum The evolutionary transition from water to land required dramatic alterations to organismal morphology, physiology, and ecology. Among extant fishes, the ability to come out of water has evolved multiple times. One of the most spectacular examples […]

TODGHAM, A.E.*; FANGUE, N.A.; SCHULTE, P.M.; IWAMA, G.K.; University of British Columbia, Vancouver: Stress tolerance and the Hsp response of tidepool sculpins, Oligocottus maculosus, acclimatized to laboratory or field conditions In nature, a fish�s thermal history is important in structuring its cellular response to stress. The plastic nature of the Hsp response and its involvement […]

MARCACCIO, N.D.; SPECKER, J.L.; University of Rhode Island, Graduate School of Oceanography; University of Rhode Island, Graduate School of Oceanography: Stress in Summer Flounder: Anesthesia Mitigates Transportation-Induced Stress Response and Increases Post-Transport Performance A significant problem affecting the mariculture of summer flounder Paralichthys dentatus, is the incidence of post-transport epizootic, leading to significant delayed mortality. […]

RICHARDS, J.G.*; SCHULTE, P.M.; University of British Columbia, Vancouver; University of British Columbia, Vancouver: Metabolic acclimation to hypoxia in Fundulus heteroclitus Environmental hypoxia has profound effects on pathways involved in ATP production. During periods of acute hypoxia, ATP is primarily produced by �anaerobic� metabolism and there is a down regulation of aerobic metabolism. During acclimation […]

LANKFORD, S.E.; MILLER, R.A.; ADAMS, T.E.; CECH JR., J.J.; Univ. of California, Davis; Univ. of California, Davis; Univ. of California, Davis; Univ. of California, Davis: Hormonal, Metabolic, and Performance Based Measurements of Chronic Stress in Green Sturgeon, Acipenser medirostris To simulate chronic stress, groups of three 0+ green sturgeon were place into flow-through, indoor tanks […]

BIGA, PR; CAIN, KD; HARDY, RW; OVERTURF, K; OTT, TL; Marine Biological Laboratory, Woods Hole, MA; University of Idaho, Moscow, ID; University of Idaho, Moscow, ID; USDA, ARS, Hagerman, ID; University of Idaho, Moscow, ID: Growth hormone differentially regulates muscle myostatin-I and �II and increases circulating cortisol in rainbow trout (Oncorhynchus mykiss). Myostatin negatively regulates […]

BUCKLEY, Bradley A.; GRACEY, Andrew Y.; SOMERO, George N.; Stanford University, Hopkins Marine Station; Stanford University, Hopkins Marine Station; Stanford University, Hopkins Marine Station: DNA microarray analysis of gene expression during heat stress in the eurythermal goby Gillichthys mirabilis Exposure to elevated but sub-lethal temperatures can have deleterious effects at the cellular level, including abnormal […]

IZEM, R*; MARRON, JS; KINGSOLVER, JG; UNC-Chapel Hill; UNC-Chapel Hill; UNC-Chapel Hill: Analyzing Variation in Thermal Performance Curves A thermal performance curve (TPC) represents the performance of an individual or genotype as a continuous function of temperature. Patterns of genetic variation in thermal performance curves and other continuous reaction norms are important for determining evolutionary […]

TOMANEK, Lars; Univ. of California, Davis: 2-DE comparison of the heat-shock protein complement in intertidal Tegula congeners. Species of the genus Tegula occupy widely varying thermal habitats along the transition from the sub- to the intertidal zone and show distinct biogeographic distribution ranges. Separation of proteins using 1D gel-electrophoresis has shown that these congeners vary […]
