Massachusetts, Boston: Genetic Divergence with Depth and Distance in a Deep-Sea Bivalve, Deminucula atacellana Evolutionary origins are obscure for the diverse and highly endemic fauna of deep-sea soft-sediment environments. Current knowledge of geographic […]

Dispersal and climate history in sea star population genetic structure
HART, M.W.*; SUNDAY, J.; KEEVER, C.C.; Simon Fraser Univ.; Simon Fraser Univ.; Simon Fraser Univ.: Dispersal and climate history in sea star population genetic structure The NE Pacific bat star Patiria miniata is widespread and abundant in southern and central California, the outer coasts of British Columbia, and southeast Alaska, but is rare or absent […]
Disparate evolutionary trajectories in two hyperdiverse tropical marine gastropod genera
MEYER, Christopher P.*; KOHN, Alan J.; University of Washington and Univ. of Florida; University of Washington: Disparate evolutionary trajectories in two hyperdiverse tropical marine gastropod genera In tropical seas, coral reef-associated environments support maximal benthic biodiversity. Hyperdiverse genera (containing 100->500 species) in several animal groups contribute importantly to the high species diversity. We are investigating […]
Why are our toes so tiny Walking, running and the evolution of a short forefoot in the genus Homo
Meeting Abstract 17.4 Jan. 4 Why are our toes so tiny? Walking, running and the evolution of a short forefoot in the genus Homo ROLIAN, Campbell*; LIEBERMAN, Daniel E.; SCOTT, John W.; Harvard University; Harvard University; Vanderbilt University rolian@fas.harvard.edu Humans have an extremely short forefoot relative to total foot length. The derived pedal proportions of humans are […]
The energetics of quadrupedal and bipedal locomotion in chimpanzees
Meeting Abstract 17.1 Jan. 4 The energetics of quadrupedal and bipedal locomotion in chimpanzees RAICHLEN, D.A.*; PONTZER, H.; SOCKOL, M.D.; University of Arizona; Washington University; University of California, Davis raichlen@email.arizona.edu For decades, researchers have worked to discover general principles governing the energetic costs of terrestrial locomotion. The Force Production Hypothesis satisfies many of the requirements of a […]
Small-bodied primates adapt asymmetrical gait dynamics to locomotion on arboreal substrates
Meeting Abstract 17.6 Jan. 4 Small-bodied primates adapt asymmetrical gait dynamics to locomotion on arboreal substrates YOUNG, JW; Stony Brook University jwyoung@ic.sunysb.edu Whereas the dynamics of symmetrical gaits (i.e., walking and running) in primates have been well researched, their use of asymmetrical gaits (i.e., galloping and bounding) remains understudied. Asymmetrical gaits are usually associated with greater peak […]
Humans use a unique mechanism to stabilize the head during running
Meeting Abstract 17.3 Jan. 4 Humans use a unique mechanism to stabilize the head during running LIEBERMAN, DE*; BRAMBLE, DM; RAICHLEN, DA; Harvard University; University of Utah; Uinversity of Arizona danlieb@fas.harvard.edu Mammals must stabilize the head during running to keep angular accelerations of head within the operating range of the vestibulo-ocular (VOR) reflexes. However, several unique aspects […]
Effects of limb placement on the mechanics of quadrupedal arboreal locomotion
Meeting Abstract 17.5 Jan. 4 Effects of limb placement on the mechanics of quadrupedal arboreal locomotion LAMMERS, A.R.; Cleveland State Univ., Ohio a.Lammers13@csuohio.edu Quadrupedal animals which frequently move on arboreal substrates face unique challenges to maintaining stability. One such challenge to overcome is the tendency to topple over the sides of the branch. Any limb contact will […]
Complex Effect of Limb Length on Cost of Transport in Running Humans
Meeting Abstract 17.2 Jan. 4 Complex Effect of Limb Length on Cost of Transport in Running Humans MYERS, M.J.*; WALL-SCHEFFLER, C.M.; WEAVER, T.D.; STEUDEL-NUMBERS, K.L.; College of St. Catherine, St. Paul; University of Wisconsin-Madison; University of California-Davis; University of Wisconsin-Madison mjmyers@stkate.edu It is unclear whether longer limbs relative to body mass (BM) should increase the cost of […]
Visceral topography in elongate vertebrates
Meeting Abstract 17.2 Thursday, Jan. 3 Visceral topography in elongate vertebrates WARD, A.B.*; KLEY, N.J.; Adelphi University; Stony Brook University award@adelphi.edu Body elongation has evolved multiple times among vertebrates. In general, this involves modifications to the vertebral column such that there are either more vertebrae or longer vertebrae. Such modifications can occur across the entire vertebral column […]
