Meeting Abstract 10-8  Saturday, Jan. 4 09:45 – 10:00  Do diverse feather nanostructures increase the colorfulness of iridescent plumage? NORDéN, KK*; ELIASON, CM; STODDARD, MC; Princeton University, Princeton, NJ; Field Museum of Natural History, Chicago, IL; Princeton University, Princeton, NJ knorden@princeton.edu Iridescent bird coloration produces some of the most spectacular color displays in the natural world, yet […]

Meeting Abstract 10-7  Saturday, Jan. 4 09:30 – 09:45  Divergent processes drive parallel evolution in marine and freshwater fishes FRIEDMAN, ST*; COLLYER, ML; PRICE, SA; WAINWRIGHT, PC; University of California Davis; Chatham University; Clemson University; University of California Davis sarahtfried@gmail.com Investigating the patterns of evolutionary diversification is vital to understanding the processes governing the rich biodiversity of […]

COSTA, D.P.*; GALES, N.J; GOEBEL, M.A.: The Role of Physiology in the Behavior of Diving Mammals Diving animals offer a unique opportunity to study the role physiology in limiting behavior. An important component of the physiological capability of any diving animal is it’s aerobic dive limit (ADL). The ADL has only been measured in a […]

VEZINA, F.*; SALVANTE, K.G.; WILLIAMS, T.D.: The Metabolic Cost of Yolk Precursor Production The metabolic cost of egg production in birds is poorly understood. Previous results with European Starlings ( Sturnus vulgaris) suggested that physiological adjustments, namely production of the yolk precursors, vitellogenin (VTG) and yolk-targeted very-low density lipoprotein (VLDLy), may be responsible for an […]

Ligon, D.B.*; Peterson, C.C.: Physiological Variation in Estivation among Mud Turtles (Kinosternon spp.) Sonoran mud turtles (Kinosternon sonoriense) have long been believed to be obligately aquatic, yet recent evidence suggests that populations in the extreme eastern portion of the species’ range thrive in habitats that experience annual drying. We compared the physiological response to dry […]

ANGILLETTA, M.J.*; LEE, V.; SILVA, A.C.: How Do Embryos Incubated at Higher Temperatures Spend Less Energy During Incubation? In some reptiles, the energetic cost of development remains the same or even decreases with increased incubation temperature. The surprisingly low energy expenditure of embryos at high incubation temperatures may be caused by either of two mechanisms: […]

Lancaster, W.C.*; Ward, S.; Jones, G.; Speakman, J.R.: Energetics of Biosonar Vocalization in Stationary Insectivorous Bats Previous studies show a linkage between flight and production of biosonar calls in bats. Microchiropteran bats also emit a wide variety of calls while at rest including biosonar calls of high intensity in some species. The propensity of bats […]

ERICKSON, G.M.; LAPPIN, A.K.; VLIET, K.: Ontogeny of bite-force performance of the American alligator, Alligator mississippiensis The diet of the American alligator, Alligator mississippiensis, undergoes substantial change during ontogeny. Hatchlings typically prey upon insects and small fish. At about 0.4 m total length, frogs and reptiles as well as crustaceans are added to the diet. […]

MOON, B.R.*; URQUHART, M.R.; LINDSTEDT, S.L.; CONLEY, K.E.: Long tendons reduce muscle shortening in rattlesnake tails The tailshaker muscles of western diamondback rattlesnakes (Crotalus atrox) sustain high frequency contractions that involve minimal shortening. Muscle segments in the proximal part of the tail have long tendons that insert onto the distal tail vertebrae; segments in the […]
