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 […]
Evolutionary digit reduction and beam mechanics in fossil and extant horses
Meeting Abstract 102-3 Wednesday, Jan. 6 14:00 Evolutionary digit reduction and beam mechanics in fossil and extant horses MCHORSE, B.K.*; PIERCE, S.E.; BIEWENER, A.A.; Harvard University; Harvard University; Harvard University bmchorse@fas.harvard.edu Though extant horses consist of a single genus that is large, cursorial, and grazing, their fossil record shows considerable diversity and repeated evolution in these traits.

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 […]
