Ontogeny of circular muscle ultrastructure and implications for jet locomotion in oval squid (Sepioteuthis lessoniana)
THOMPSON, J.T.; KIER, W.M.; St. Joseph’s University; Univ. of North Carolina: Ontogeny of circular muscle ultrastructure and implications for jet locomotion in oval squid (Sepioteuthis lessoniana) We investigated growth-related changes in the morphology and movement of the mantle of the Oval Squid, Sepioteuthis lessoniana. The maximum rate of mantle contraction during escape-jet locomotion was highest […]
Microhabitats and Ecomorphologies of Cottus species
KERFOOT, J.R.*; SCHAEFER, J.F.; Florida Institute of Technology; Southern Illinois University Edwardsville: Microhabitats and Ecomorphologies of Cottus species Phenotypes of fishes act as fundamental constraints upon their ecologies; morphology shapes ecological attributes through its effect on performance. Field and laboratory studies were conducted to investigate the relationships between morphological attributes and microhabitat use in Cottus […]
Linking wake structure, kinematics, and mechanics for oscillatory propulsion
TYTELL, Eric D.; Harvard University: Linking wake structure, kinematics, and mechanics for oscillatory propulsion Many studies have examined either the kinematics or the hydrodynamics of fish swimming, but few have looked at both simultaneously. By directly observing the wakes that result from different kinematics, a more detailed description of the underlying mechanism may be produced. […]
Gas bladder movement in lionfishes a novel mechanism for control of pitch
HORNSTRA, H. M.*; HERREL, A.; MONTGOMERY, W. L.; Northern Arizona University, Flagstaff; University of Antwerp, Belgium; Northern Arizona University, Flagstaff: Gas bladder movement in lionfishes: a novel mechanism for control of pitch Lionfish (Pterois volitans) are crepuscular reef predators that stalk their prey and often hover just above the reef, maintaining unique body positions with […]
Development of pectoral fin morphology and locomotion in the zebrafish Danio rerio
THORSEN, D/H*; CASSIDY, J/J; HALE, M/E; The University of Chicago; The University of Chicago; The University of Chicago: Development of pectoral fin morphology and locomotion in the zebrafish Danio rerio Pectoral fins serve a variety of locomotor functions for fishes including propulsion, stabilization and maneuvering. The function of pectoral fins can change through development and […]
Delayed stall due to leading edge tubercles of the humpback whale flipper
FISH, Frank E.; MIKLOSOVIC, David S.; MURRAY, Mark M.; HOWLE, Laurens E.; West Chester University; U.S. Naval Academy; U.S. Naval Academy; Duke University: Delayed stall due to leading edge tubercles of the humpback whale flipper The humpback whale (Megaptera novaeangliae) is exceptional among the baleen whales in its ability to undertake acrobatic underwater maneuvers. In […]
Batoid wing skeletons a comparison of oscillatory and undulatory swimmers
SCHAEFER, J.S.; Univ. of California, Irvine: Batoid wing skeletons: a comparison of oscillatory and undulatory swimmers The skeleton of the wings of skates and rays consists of a series of radially oriented cartilaginous fin rays fanning out from the pectoral girdle. Each fin ray is segmented into longitudinally oriented skeletal elements, traditionally represented as simple […]
Thyroid hormone like metabolism and function in complex life histories
HEYLAND, Andreas; BODNAROVA, M; MOROZ, LL; Whitney Laboratory, Center for Excellence in Genomic Sciences, University of Florida, St. Augustine, FL; Whitney Laboratory, Center for Excellence in Genomic Sciences, University of Florida, St. Augustine, FL; Whitney Laboratory, Center for Excellence in Genomic Sciences, University of Florida, St. Augustine, FL: Thyroid hormone like metabolism and function in […]
Local population dynamics of a widely introduced salt marsh anemone, Nematostella vectensis
REITZEL, Adam M; FINNERTY, John R.; Boston University; Boston University: Local population dynamics of a widely introduced salt marsh anemone, Nematostella vectensis Nematostella vectensis is a euryhaline, burrowing anemone primarily inhabiting tidally-restricted salt marsh pools throughout North America, as well as the parts of England. Recent population genetic data coupled with a discontinuous range support […]
