CHRISTIANS, J.K.; WILLIAMS, T.D. *: Effects of porcine follicle-stimulating hormone on the reproductive performance of female zebra finches (Taeniopygia guttata) It has been suggested that follicle-stimulating hormone (FSH) may play a role in egg size/number trade-offs in oviparous vertebrates. We tested this hypothesis in an avian species by administering porcine FSH (pFSH) to intact, captive […]

MAPLE, M.M.: Direct and indirect effects of maternal rearing site choice on tadpole survival in the strawberry arrow poison frog, Dendrobates pumilio Parental choice of early offspring environments can have important fitness consequences for their young, especially in taxa with otherwise limited parental investment. The pathways by which site variables influence fitness will determine the […]

LOEWENSTEINER, D.A.*; TURINGAN, R.G.: Trophic ecomorphology of juvenile Cynoscion nebulosus (spotted seatrout): Intraspecific ontogenetic variability between Atlantic and Gulf populations of Florida. Variation in prey capture ability may be one of the most important factors in determining survivability and cohort success in marine teleosts, especially during the larval and juvenile stages of ontogeny. During these […]

BECK, J.L.*; TURINGAN, R.G.: The Effect of Prey Swimming Behavior on Prey-Capture Kinematics and Feeding Performance in Marine Fish Larvae It is hypothesized that the strength of a recruiting class of marine teleosts is determined by the magnitude of mortality during the larval stage of ontogeny. This study investigates the possible influence of zooplankton prey […]

GUIGAND, C.M.; TURINGAN, R.G.: Scaling of feeding kinematics and morphology of juvenile tarpon Megalops atlanticus. Scaling of feeding kinematics of juvenile tarpon Megalops atlanticus, was investigated to explore the effects of size on feeding mechanics. Eleven tarpon (127-310 mm total lengths) were filmed at 500 frames per second using a high-speed video system while feeding […]

FRANCIS, JR., A.W.*; TURINGAN, R.G.: Ontogeny of Feeding Kinematics in Southern Flounder, Paralichthys lethostigma Fish experience a number of morphological and behavioral changes through ontogeny that may have consequences for feeding performance. For pleuronectiform fishes, ontogenetic changes in functional morphology may correlate with transition from endogenous to exogenous feeding, pelagic to benthic life style, and […]

LARSON, Peter M.; REILLY, Stephen M.: Functional morphology of feeding and gill irrigation in the anuran tadpole: Electromyography and muscle function in larval Rana catesbeiana This study provides the first data on in vivo muscle activity patterns during feeding in a larval anuran. Data from unanaesthetized, unrestrained animals are also provided to verify results presented […]

SWANSON, B.O.; Northern Arizona University: Terrestrial escape response of the mudskipper: an analysis of muscle power and kinematics Recent research into steady swimming has greatly increased understanding of fish locomotion. However, studies of fish power production and performance during steady swimming are not considered maximal effort, and thus do not shed light on potential constraints […]

BECHTEL, B.F.; ASHLEY-ROSS, M.A.*; Wake Forest University: Kinematics of the transition between aquatic and terrestrial locomotion in the newt Taricha torosa Newts are capable of locomotion in both aquatic and terrestrial environments. The movements of swimming involve primarily the axial musculature, which generates traveling waves of lateral undulation. In contrast, walking uses the paired limbs […]

WARD, A.B.; University of Massachusetts Amherst: Kinematics of the pectoral fins in batfishes (Ogcocephalidae) during aquatic walking Several independent radiations of benthic fishes have modified pectoral and/or pelvic fins that allow them to walk along the bottom. Members of Lophiiformes, in particular, have highly modified pectoral (and, to a lesser extent, pelvic) musculoskeletal systems. Previous […]
