Mandibular helical axis during feeding in non-human primates
Meeting Abstract 75.3 Friday, Jan. 6 Mandibular helical axis during feeding in non-human primates IRIARTE-DIAZ, J*; TERHUNE, C.E.; ROSS, C.F.; University of Chicago; Duke University; University of Chicago jiriarte@uchicago.edu Teeth trajectories are often used for the study of mandibular movement. These trajectories, however, depend on the location of the reference point and their interpretation can be equivocal. […]
Evolution of elastic mechanisms in salamander tongues
Meeting Abstract 75.5 Friday, Jan. 6 Evolution of elastic mechanisms in salamander tongues DEBAN, Stephen*; ANDERSON, Christopher; LARGHI, Nicholas; SANDUSKY, Paula; Univ. South Florida, Tampa sdeban@usf.edu Plethodontid salamanders are characterized by specialized tongue projection, with ballistic projection evolving three times independently. All ballistic taxa project their tongues with high muscle-mass specific power output (i.e., peak instantaneous mechanical […]
Assessing biomechanical performance in extinct crocodylians a neontological model of bite-force generation and tooth pressures in fossil forms
Meeting Abstract 75.2 Friday, Jan. 6 Assessing biomechanical performance in extinct crocodylians: a neontological model of bite-force generation and tooth pressures in fossil forms GIGNAC, P.M.*; ERICKSON, G.M.; Stony Brook University; Florida State University paul.gignac@stonybrook.edu Crocodylians have dominated predatory niches at the water-land interface for over 85 million years. Like their ancestors, living species show substantial variation […]
The mechanism of tracheal collapse in beetles a multi-linked system
Meeting Abstract 75.5 Saturday, Jan. 5 The mechanism of tracheal collapse in beetles: a multi-linked system PENDAR, H*; SOCHA, JJ; Virginia Tech; Virginia Tech hpendar@vt.edu Many insects are known to augment their respiration via rhythmic tracheal compression and reinflation. A significant decrease in the volume of tracheal tubes during compression displaces air out of the body and […]
Structure & Function in Sauropsid Lungs
Meeting Abstract 75.4 Saturday, Jan. 5 Structure & Function in Sauropsid Lungs FARMER, CG*; SCHACHNER, ER; SARRAZIN, JC; University of Utah; University of Utah; University of Utah cg.frmr@gmail.com The lung is among the most diverse organs in the vertebrate body but the functional underpinnings and evolutionary history of this diversity are poorly understood. Because gas exchange in […]
Phenotypic Changes in Lung Function After Acclimation to High Altitude in Deer Mice
Meeting Abstract 75.2 Saturday, Jan. 5 Phenotypic Changes in Lung Function After Acclimation to High Altitude in Deer Mice DIAZ, S; SHIRKEY, NJ; THALER, CD; CARDULLO, RA; HAMMOND, KA*; Univ. of California, Riverside khammond@ucr.edu Small mammals living at high altitude face low O2 partial pressures, cold ambient temperatures necessitating an increase in energy expenditure. Deer mice (Peromyscus […]
Functional morphology of ventilation in four species of sculpins (Scorpaeniformes)
Meeting Abstract 75.1 Saturday, Jan. 5 Functional morphology of ventilation in four species of sculpins (Scorpaeniformes) FARINA, SC*; FERRY, LA; Cornell University; Arizona State University scf59@cornell.edu Fish move water over the gill tissue using pumps in both the buccal and opercular chambers. The pump in the opercular chamber consists of the opercular bones, or the gill cover, […]
Developmental changes in tracheal system structure and function in the caterpillar, Manduca sexta
Meeting Abstract 75.6 Saturday, Jan. 5 Developmental changes in tracheal system structure and function in the caterpillar, Manduca sexta GREENLEE, K. J.*; SOCHA, J. J.; EUBANKS, H. B.; LEE, W.-K.; KIRKTON, S. D.; North Dakota State University; Virginia Tech; Jackson State University; Argonne National Laboratory; Union College kendra.greenlee@ndsu.edu Abdominal pumping in caterpillars has only been documented during […]
A Comparative Study of Cetacean Respiratory Mechanics Implications for diving and health assessment
Meeting Abstract 75.3 Saturday, Jan. 5 A Comparative Study of Cetacean Respiratory Mechanics: Implications for diving and health assessment PISCITELLI, M.A.*; LILLIE, M.A.; RAVERTY, S.A.; SHADWICK, R.E.; Univ. of British Columbia, Vancouver; Univ. of British Columbia, Vancouver; British Columbia Ministry of Agriculture, Food, and Fisheries; Univ. of British Columbia, Vancouver piscitellim@gmail.com The cetacean respiratory system has undergone […]
