VILLARIN, J.J.*; SCHAEFFER, P.J.; CARLSEN, R.C.; Univ. of California, Davis; Washington Univ School of Medicine; Univ. of California, Davis: Non-Contractile Functions in Skeletal Muscle: Adaptation and Interactions Vertebrate skeletal muscle is most often discussed in the context of contractile function, which provides a broad range of functions: locomotion, breathing, posture, feeding, sound production, and so […]

KINSEY, Stephen T.; BOYLE, Kim-Laura; Univ. of North Carolina at Wilmington: Mitochondrial distribution and glycogen dynamics suggest diffusion constraints in muscle fibers of the blue crab, Callinectes sapidus. The scaling of mitochondrial distribution, citrate synthase activity and post-contractile glycogen recovery was examined in muscle fibers of the blue crab, Callinectes sapidus. The fast-twitch muscle fibers […]

SZUCSIK, A.

ERICKSON, J.R.; MOERLAND, T.S.; Florida State University; Florida State University: Calcium-binding characteristics of parvalbumin isolated from the Arctic cod (Boreogadus saida) The calcium-binding protein parvalbumin (PV) is highly abundant in muscle and is thought to sequester intracellular Ca2+ after a contraction, thus facilitating relaxation. The dissociation constant (Kd) of Ca2+ from PV isolated from the […]

HORTON, J.M.*; DRUCKER, E.G.; SUMMERS, A.P.; Univ. of Massachusetts, Amherst; Univ. of California, Irvine; Univ. of California, Irvine: Swiftly swimming fish show evidence of stiff spines Fast swimming fishes typically have low amplitude and high frequency tail beats, an indication of a stiff body. Previous work has shown that cartilaginous fishes increase intramuscular myotomal pressure […]

EIDIETIS, L; Univ. of Michigan: Scaling of escape response performance over ontogeny for Rana sylvatica tadpoles Rana sylvatica tadpoles escape from sit-and-wait predators via tearing from a predator grasp, accelerating so that the predator cannot gain a grasp, or some combination of these. Thus, escape success depends on tail force production. Force production depends on […]

MCHENRY, Matthew/J; LAUDER, George/V; Harvard Univ.; Harvard Univ.: How do ontogenetic changes in morphology, behavior, and hydrodynamics affect the performance of gliding in zebrafish? As fish grow from larvae to adults, changes in their morphology and behavior cause unpredictable alterations in swimming performance. On example of such ontogenetic change is provided by the routine beat-and-glide […]

STANDEN, E.M.; LEVINE, R.P.; DOMENICI, P.; Harvard University; University of Massachusetts Amherst; CNR-IAMC c/o International Marine Centre: Fast and slow escape manoeuvres in the spiny dogfish (Squalus acanthias) Little is known about the fast-start behavior of escape response in chondrichthyans. The aims of this study are to examine the escape response in the spiny dogfish […]

CHADWELL, BA*; VICHOT, D; HARRIS, C; ASHLEY-ROSS, MA; Wake Forest University; Wake Forest University; Wake Forest University; Wake Forest University: Dorsal fin use during the escape response in largemouth bass (Micropterus salmoides). Though the fast-start escape response in fish is powered primarily by the axial musculature, the median fins are in a position to increase […]

HSIEH, S.T.; Harvard University: Comparative locomotor characteristics of two amphibious blennies, Alticus arnoldorum and Praealticus labrovittatus Amphibious behavior is found in at least 12 families of fishes. Whereas most blennies (family Blenniidae) are fully-aquatic, at least seven of the 53 genera have amphibious species. I have been examining the amphibious locomotor repertoire of the Pacific […]
