Meeting Abstract 14.4 Monday, Jan. 4 Non-linear Viscoelastic Properties of Squalus acanthias Vertebral Columns Bending Dynamically PORTER, M.E.*; EWOLDT, R.H.; LONG, J.H; Vassar College; University of Minnesota; Vassar College meporter@vassar.edu In engineering, any system is expected to behave linearly if the mechanical inputs are sufficiently small, even if the individual elements are non-linear. The properties of linear […]

Locomotion by flexible foils effect of length and stiffness on performance
Meeting Abstract 14.1 Monday, Jan. 4 Locomotion by flexible foils: effect of length and stiffness on performance BAKER, T.V.*; ANDERSON, E.J.; LIM, J.L.; LAUDER, G.V.; Grove City College; Grove City College; Harvard University; Harvard University bakertv1@gcc.edu The propulsive and control surfaces of swimming and flying organisms are flexible and variously shaped. These physical characteristics affect how such […]
Functional morphology and biomechanics of ratfish steady swimming
Meeting Abstract 14.6 Monday, Jan. 4 Functional morphology and biomechanics of ratfish steady swimming FOSTER, K. L.*; HIGHAM, T. E.; Univ. of British Columbia; Clemson University fosterk@interchange.ubc.ca The functional morphology and biomechanics of body-caudal fin swimmers, and more recently median-paired fin swimmers have been studied extensively for a variety of chondrichthyan and osteichthyan fishes. However, functional morphology […]
Exploring the adaptive significance of morphological specializations of the pectoral fins among benthic scorpaeniform fishes
Meeting Abstract 14.5 Monday, Jan. 4 Exploring the adaptive significance of morphological specializations of the pectoral fins among benthic scorpaeniform fishes TAFT, Natalia K.; University of Chicago taft.nk@gmail.com Several groups of fishes use the pectoral fins for routine substrate contact and exhibit morphological specializations that have been hypothesized to be adaptive for a benthic lifestyle. Here I […]
Dorsal Fin Function in Spiny Dogfish and Bamboo Sharks during Steady Swimming
Meeting Abstract 14.3 Monday, Jan. 4 Dorsal Fin Function in Spiny Dogfish and Bamboo Sharks during Steady Swimming MAIA, A.*; WILGA, C.D.; Univ. of Rhode Island amaia@mail.uri.edu White-spotted bamboo sharks, Chiloscyllium plagiosum, inhabit complex reef habitats and are highly maneuverable. Spiny dogfish, Squalus acanthias, occupy a variety of coastal and continental platform habitats and use the water […]
The effects of conspecific playbacks on behavior and hormone modulation in Etheostoma crossopterum
Meeting Abstract 14.3 Tuesday, Jan. 4 The effects of conspecific playbacks on behavior and hormone modulation in Etheostoma crossopterum SPEARES, Patty*; JOHNSTON, Carol; Auburn University pas0004@auburn.edu Social cues have been shown to regulate steroid hormones, and therefore ultimately affect behaviors critical to survival and reproduction in many organisms. Interactions between vocalizations, hormones, and behavior have been well […]
The effect of testosterone on molt in House Finches (Carpodacus mexicanus)
Meeting Abstract 14.4 Tuesday, Jan. 4 The effect of testosterone on molt in House Finches (Carpodacus mexicanus) BRAZEAL, K.R.*; HAHN, T.P.; Univ. of California, Davis; Univ. of California, Davis krbrazeal@ucdavis.edu In seasonally-breeding birds, the timing of the transition between breeding and molt represents an important life-history trade-off between the benefits of extended current reproduction and the costs […]
Patterns of DHT variation in waterfowl and their relationship with social environment and genital morphology
