Meeting Abstract P3.62  Jan. 6  Hydrodynamic stability of swimming turtles: correlations with shell shape? RIVERA, G.*; BLOB, R. W.; Clemson University grivera@clemson.edu Hydrodynamic stability in swimming animals can be defined as the ability to resist recoil movements of the body and maintain a given trajectory. Morphological features, such as body depth and rigidity, have been suggested to […]

Meeting Abstract P3.51  Jan. 6  Hold �Em or Fold �Em? Hindlimb Flight Posture in Birds SHEPARD, L.S.*; MEYERS, R.A.; Weber State University, Ogden, UT; Weber State University, Ogden, UT rmeyers@weber.edu While flying, birds hold their legs in one of two different ways: either in an extended position with the legs trailing behind the body or in a […]

Meeting Abstract P3.68  Jan. 6  Hindlimb flexor muscle strain during swimming in the toad, Bufo marinus MILLER, Dery*; GILLIS, Gary; Mount Holyoke College; Mount Holyoke College ggillis@mtholyoke.edu A number of electromyographic (EMG) analyses of limb function during anuran swimming have shown that major hindlimb extensor muscles are activated nearly simultaneously once per locomotor cycle. In contrast, recent […]

Meeting Abstract P3.116  Jan. 6  GLYCOGEN AND PROGLYCOGEN LEVELS ARE HIGHER IN MALE VERSUS FEMALE TROUT HEARTS BOLINGER, Mark T.*; BATTIPROLU, Pavan K.; RODNICK, Kenneth J.; Idaho State University bolimark@isu.edu Glycogen, the storage form of glucose, is potentially an important energy source in the teleost heart. The heart of rainbow trout (Oncorhynchus mykiss) may become oxygen deficient […]

Meeting Abstract P3.53  Jan. 6  Free flight yaw turns of stalk-eyed flies (Cyrtodopsis dalmanni) RIBAK, G*; SWALLOW, J.G; Univ of South Dakota, Vermillion; Univ of South Dakota, Vermillion gribak@usd.edu The eyes of stalk-eyed flies (Diopsidae) are positioned at the end of rigid peduncles projecting laterally from the head. The length of these eye-stalks is sexually selected in […]

Meeting Abstract P3.55  Jan. 6  Forelimb kinematics and hand postures in the rhesus monkey (Macaca mulatta) PATEL, B.A.; Stony Brook University bapatel@ic.sunysb.edu A digitigrade limb posture, considered to be a hallmark of cursoriality in terrestrial animals, is perceived to: 1) increase effective limb length (ELL) to achieve preferred or higher locomotor speeds more efficiently by increasing step […]

Meeting Abstract P3.119  Jan. 6  Fasting increases 15N/14N ratios in the uric acid of Anolis carolinensis and Uta Stansburiana CASTILLO, L.P.**; HATCH, K.A.; Brigham Young University, Provo, UT; Brigham Young University, Provo, UT lp_lalis@hotmail.com It has been suggested that the metabolic state (catabolic or anabolic) can be determined from the 15N/14N ratios of an animal�s tissues. In […]

Meeting Abstract P3.141  Jan. 6  Existence of sex steroids in ovary of amphioxus, Branchiostoma belcheri KUBOKAWA, Kaoru*; MIZUTA, Takanobu; ORI, Unv of Tokyo, Japan; ORI, Unv of Tokyo, Japan kubokawa@ori.u-tokyo.ac.jp The amphioxus, cephalochordate is the closest living invertebrate relative of vertebrates, and study of amphioxus genes would provide important information on the evolutionary linkage between invertebrate to […]
