Meeting Abstract 43.3 Monday, Jan. 5 Gliding Geckos actively use tails for turning. JUSUFI, A*; GAO, P; FULL, RJ; DUDLEY, R; Univ. of California, Berkeley ardianj@berkeley.edu During free fall geckos reorient from an upside-down to a rightside-up posture by swinging their tail in one direction causing the body to rotate in the other as predicted by the […]

Forelimb skeletal kinematics of chukar partridges (Alectoris chukar) during wing-assisted incline running and ascending flight
Meeting Abstract 43.5 Monday, Jan. 5 Forelimb skeletal kinematics of chukar partridges (Alectoris chukar) during wing-assisted incline running and ascending flight BAIER, DB*; GATESY, SM; DIAL , KP; Brown University; Brown University; Montana State University David_Baier@brown.edu The origin of avian flight remains controversial. Recent studies have shown that birds use their wings not only for flight, but […]
Cross-sectional geometry of the forelimb skeleton and flight mode in pelecaniform birds
Meeting Abstract 43.4 Monday, Jan. 5 Cross-sectional geometry of the forelimb skeleton and flight mode in pelecaniform birds SIMONS, E. L. R.*; O’CONNOR, P. M.; Ohio Univ, Athens; Ohio Univ, Athens er238604@ohio.edu Pelecaniforms are a group of marine birds that vary greatly in body size, whole wing shape, and flight mode. Members of this clade utilize static […]
Aerodynamics of the northern flying squirrel (Glaucomys sabrinus)
Meeting Abstract 43.2 Monday, Jan. 5 Aerodynamics of the northern flying squirrel (Glaucomys sabrinus) BAHLMAN, Joseph Wm*; RISKIN, Daniel K.; IRIARTE-DIAZ, Jose; SWARTZ, Sharon; Brown University; Brown University; University of Chicago; Brown University joseph_bahlman@brown.edu Most studies on mammalian gliders deduce glide aerodynamics from the location of the launch and landing, using an assumption of steady-state aerodynamics. During […]
The celebrated jumping frogs of Calaveras County how far can a frog really jump
Meeting Abstract 43.1 Tuesday, Jan. 5 The celebrated jumping frogs of Calaveras County: how far can a frog really jump? ABBOTT, E.M.*; MARSH, R.L.; ASTLEY, H.C.; AZIZI, E.; ROBERTS, T.J.; Brown Univ.; Northeastern Univ.; Brown ; Brown ; Brown Emily_Abbott@brown.edu True performance limits, as defined by maximal physiological function, can be difficult to identify. Estimating maximal performance […]
Patterns of axial and pelvic muscle architecture and fiber composition in frogs with different locomotor modes
Meeting Abstract 43.5 Tuesday, Jan. 5 Patterns of axial and pelvic muscle architecture and fiber composition in frogs with different locomotor modes JORGENSEN, M.E.; Ohio University mj207406@ohio.edu The composition of fiber types in a muscle, along with its gross architecture corresponds to muscle function. In frog limbs, jumping involves muscles comprised mainly of high force-producing glycolytic muscle […]
Loading effects on jumping and running in green anole lizards (Anolis carolinensis)
Meeting Abstract 43.6 Tuesday, Jan. 5 Loading effects on jumping and running in green anole lizards (Anolis carolinensis) KUO, CY*; IRSCHICK, DJ; Univ. of Massachusetts Amherst; Univ. of Massachusetts Amherst chiyun@bio.umass.edu Animals in nature commonly encounter the problem of large loads that they must carry, such as when they are pregnant, have consumed a large meal, etc. […]
Decoupling of muscle shortening and joint kinematics during frog jumping
Meeting Abstract 43.2 Tuesday, Jan. 5 Decoupling of muscle shortening and joint kinematics during frog jumping ASTLEY, H. C.*; ROBERTS, T. J.; Brown University; Brown University henry_astley@brown.edu Elastic tendons can decouple changes in muscle length from changes in joint angle, allowing the muscle to function at closer to optimal conditions for force production and allowing elastic energy […]
A New Look at the Evolution of Jumping in Frogs
Meeting Abstract 43.3 Tuesday, Jan. 5 A New Look at the Evolution of Jumping in Frogs REILLY, S. M.*; JORGENSEN, M. E.; ESSNER, R. L. ; Ohio University reilly@ohio.edu Frog jumping is one of the most enigmatic and paradoxical evolutionary transitions in vertebrate evolution. The current hypothesis for the evolution of jumping in frogs follows from the […]
A Comparison of Jumping Behavior in the Rocky Mountain Tailed Frog, Ascaphus montanus and Fire-bellied Toad, Bombina orientalis
Meeting Abstract 43.4 Tuesday, Jan. 5 A Comparison of Jumping Behavior in the Rocky Mountain Tailed Frog, Ascaphus montanus and Fire-bellied Toad, Bombina orientalis ESSNER, R.L.*; SUFFIAN, D.J.; REILLY, S.M.; Southern Illinois University Edwardsville; Southern Illinois University Edwardsville; Ohio University ressner@siue.edu Rocky Mountain tailed frogs, Ascaphus montanus (Anura: Leiopelmatidae) are semi-aquatic anurans belonging to a basal clade […]
