Meeting Abstract P1.80 Tuesday, Jan. 4 The Evolution of Cranial Vasculature in Ruminant Artiodactyls O’BRIEN, Haley D.*; DUFEAU, David; STEVENS, Nancy J; Ohio University; Ohio University; Ohio University Haley.D.OBrien@gmail.com The carotid rete is a cranial vascular structure found within the cavernous venous sinus of most artiodactyls. It plays an important physiological role whereby it selectively maintains cooler […]

The Energetics of Bipedal Locomotion Over Uneven Terrain
Meeting Abstract P1.94 Tuesday, Jan. 4 The Energetics of Bipedal Locomotion Over Uneven Terrain CHANNON, A J*; DALEY, M A; Royal Veterinary College, UK; Royal Veterinary College, UK achannon@rvc.ac.uk The mechanics of animal locomotion over flat level terrain is well understood, but our understanding of the way that animals move over unpredictable or pertubatory ground remains limited. […]
The Effect of Hypoxia and Hyperoxia on Dragonfly Development A Link Between Paleozoic Oxygen Levels and Insect Gigantism
Meeting Abstract P1.83 Tuesday, Jan. 4 The Effect of Hypoxia and Hyperoxia on Dragonfly Development: A Link Between Paleozoic Oxygen Levels and Insect Gigantism WEED, M.D.*; MUNOZ, E.E.; HARRISON, J.F.; VANDENBROOKS, J.M.; Arizona State University; Arizona State University; Arizona State University; Arizona State University mdweed@asu.edu During the Paleozoic Era (~300 mya), it is hypothesized that an increase […]

Testosterone and aggression in free-ranging male Cassin’s Sparrows, Poecile cassinii
Meeting Abstract P1.149 Tuesday, Jan. 4 Testosterone and aggression in free-ranging male Cassin’s Sparrows, Poecile cassinii DEVICHE, Pierre J*; DAVIES, Scott; FOKIDIS, Bobby; HURLEY, Laura; Arizona State University; Arizona State University; Arizona State University; Arizona State University deviche@asu.edu According to the “challenge hypothesis”, male birds in breeding condition increase testosterone (T) secretion during periods of enhanced aggression […]
Subcellular Localization of Aquaporin-2 During Salinity Adaptation in the Ribbed Mussel
Meeting Abstract P1.139 Tuesday, Jan. 4 Subcellular Localization of Aquaporin-2 During Salinity Adaptation in the Ribbed Mussel KAPPER, M.A.; Central Connecticut State University kapper@ccsu.edu During adaptation to increases in environmental salinity osmoconforming invertebrates typically modify the intracellular solute load by synthesis of free amino acids. In the ribbed mussel, Geukensia demissa, alanine is used as the immediate […]
Stabilization of Escherichia coli Methionine Cycle Upon Simulated Insertion of Arabidopsis Thaliana MMT Enzyme
Meeting Abstract P1.88 Tuesday, Jan. 4 Stabilization of Escherichia coli Methionine Cycle Upon Simulated Insertion of Arabidopsis Thaliana MMT Enzyme JALLI, I.S.*; NIJHOUT, H.F.; Duke University, Durham; Duke University, Durham isj@duke.edu The methionine cycle is a metabolic network that lies at the intersection of many critical cell processes such as DNA synthesis, and DNA and histone methylation. […]
Specific estrogenic activity and intra-specific variation in avian egg size application of an ER-CALUX bioassay
Meeting Abstract P1.75 Tuesday, Jan. 4 Specific estrogenic activity and intra-specific variation in avian egg size: application of an ER-CALUX bioassay FRONSTIN, M.M.*; WILLIAMS, T.D.; Simon Fraser University; Simon Fraser University mfronsti@sfu.ca Avian egg mass varies considerably within species but the mechanisms underlying this phenotypic plasticity are largely unknown. For example, environmental factors (e.g. food supplementation, ambient […]
Small Clade Peripheralization in Three Flycatcher Radiations
Meeting Abstract P1.78 Tuesday, Jan. 4 Small Clade Peripheralization in Three Flycatcher Radiations CORBIN, CE*; MILES, DB; Bloomsburg University; Bloomsburg University ccorbin@bloomu.edu Recently interests in evolutionary morphology are growing. This is especially true for analysis of association between morphological diversity and species diversification. One extension of this analysis is niche, and concomitantly, morphospace filling. As a clade […]
