Guppy offspring are born at different stages of morphological and functional maturity among populations
Meeting Abstract 102-5 Wednesday, Jan. 6 14:30 Guppy offspring are born at different stages of morphological and functional maturity among populations DIAL, T.R.*; BRAINERD, E.L.; Brown University; Brown University terry_dial@brown.edu The Trinidadian guppy, a livebearing fish, has proved a fruitful model for studying rapid evolution in the field. Reduced predation in headwaters rapidly leads to stiff competition […]

Comparative axial musculature across shark families implications for cephalofoil lift generation
Meeting Abstract 102-4 Wednesday, Jan. 6 14:15 Comparative axial musculature across shark families: implications for cephalofoil lift generation HOFFMANN, S. L.*; PORTER, M. E.; Florida Atlantic University shoffmann2014@fau.edu Hammerhead sharks are known for their unique, dorso-ventrally compressed head called a cephalofoil. Due to its aerodynamic shape and anterior location, previous researchers hypothesized that the cephalofoil acts as […]
A simple physical model suggests a hydrostat-like interaction within individual skeletal muscles
Meeting Abstract 102-6 Wednesday, Jan. 6 14:45 A simple physical model suggests a hydrostat-like interaction within individual skeletal muscles SLEBODA, D.A.*; ROBERTS, T.J.; Brown University; Brown University david_sleboda@brown.edu Fluid filled cylinders reinforced by stiff fibers (commonly referred to as helically-wound hydrostats) are ubiquitous in biological systems. Functionally, they have been shown to provide locomotor and postural support […]
