Seasonal heterothermy correlates with lower phenotypic flexibility of energetics
Meeting Abstract P3.85 Monday, Jan. 6 15:30 Seasonal heterothermy correlates with lower phenotypic flexibility of energetics BORATYNSKI, J.S.*; JEFIMOW, M.; WOJCIECHOWSKI, M.S.; Nicolaus Copernicus Univ., Torun, Poland; Nicolaus Copernicus Univ., Torun, Poland; Nicolaus Copernicus Univ., Torun, Poland jan.boratynski@gmail.com Heterothermy and phenotypic flexibility enable animals to survive in seasonally changing environments, either by “escaping” from excessive energy expenditure […]
Seasonal Patterns of Testosterone Production and Singing Behavior but not Variation in Song Control Region Volumes in Ramphocelus carbo (Thraupinae), an Endemic Amazon Songbird
Meeting Abstract P3.196 Monday, Jan. 6 15:30 Seasonal Patterns of Testosterone Production and Singing Behavior but not Variation in Song Control Region Volumes in Ramphocelus carbo (Thraupinae), an Endemic Amazon Songbird. QUISPE, R*; GAHR, M; Max Planck Institute for Ornithology rquispe@orn.mpg.de In songbirds, the development and production of song are regulated by a network of interconnected brain […]
Scaling of water loss, diffusion and ventilation in Scarab beetles at rest and during hypoxia
Meeting Abstract P3.155 Monday, Jan. 6 Scaling of water loss, diffusion and ventilation in Scarab beetles at rest and during hypoxia CAMPBELL, JB*; DUELL, ME; KLOK, CJ; HARRISON, JF; Arizona State University jacob.campbell.1@asu.edu Due to the scaling of surface-to-volume ratios and metabolic rates, smaller insects desiccate more rapidly than those larger. Water loss occurs through multiple avenues […]
Salamanders Head Over Heels
Meeting Abstract P3.139 Monday, Jan. 6 15:30 Salamanders Head Over Heels BAKER, EM*; HESSEL, A; NISHIKAWA, K; Northern Arizona University; Northern Arizona University; Northern Arizona University emb324@nau.edu In geckos, falling is like jumping because the tail corrects direction of movement. A study by Ardian et al. showed that geckos use their tails to keep from injuring themselves […]
Role of light wavelength in the circadian entrainment of the starlet sea anemone, Nematostella vectensis
Meeting Abstract P3.190 Monday, Jan. 6 15:30 Role of light wavelength in the circadian entrainment of the starlet sea anemone, Nematostella vectensis HUMBEL, E.*; REITZEL, A.M.; University of North Carolina, Charlotte ehumbel@uncc.edu Circadian clocks play an integral role for regulating diel oscillations in animal behavior and are generally entrained by light in the visible spectrum. At the […]
Role of Lateral Undulation in Salamander Locomotion
Meeting Abstract P3.136 Monday, Jan. 6 15:30 Role of Lateral Undulation in Salamander Locomotion VEGA, CM*; ASHLEY-ROSS, MA; Wake Forest University vegacm11@wfu.edu With the exception of turtles, lateral undulation of the vertebral column is an important characteristic of sprawling-postured tetrapods’ locomotion. To elucidate the contribution of lateral undulation in swimming, underwater walking and terrestrial walking, we experimentally […]
Respiratory exchange ratios in grasshoppers upon life-extending dietary restriction or ovariectomy
Meeting Abstract P3.61 Monday, Jan. 6 15:30 Respiratory exchange ratios in grasshoppers upon life-extending dietary restriction or ovariectomy AWAN, A*; WILLIAMS, CM; HAHN, DA; HATLE, JD; Univ. of North Florida; Univ. of Florida; Univ. of Florida; Univ. of North Florida jhatle@unf.edu Reduced reproduction and dietary restriction each extend lifespan in many animals. Because the degree of dietary […]
