Meeting Abstract 30.5 Jan. 5 Feeding Mechanisms in Rodents DRUZINSKY, R.E.; Governors State University r-druzinsky@govst.edu The Rodentia is a remarkably successful order, comprising roughly half of the extant species of the Mammalia. Rodents share a suite of derived characters of the jaw apparatus. These characters include a single incisor in each quadrant of the dentition, upper and […]

Building divergent dentitions by regulation of tooth addition
Meeting Abstract 30.6 Jan. 5 Building divergent dentitions by regulation of tooth addition SMITH, Moya M; KCL Dental Institute Guy’s and St Thomas’ Hospitals moya.smith@kcl.ac.uk The dentition in each clade of gnathostomes is unique and shows great diversity in patterns for tooth addition and replacement, each adapted to a specific feeding niche. The formation of a sub-epithelial […]
Behavior and Morphology of Aquatic Feeding in Pipid Frogs
Meeting Abstract 30.2 Jan. 5 Behavior and Morphology of Aquatic Feeding in Pipid Frogs CARRENO, C.A.*; NISHIKAWA, K.C.; Northern Arizona University; Northern Arizona University cac36@nau.edu Feeding behavior and morphology was examined in the pipid frogs, Pipa pipa, Xenopus laevis, Hymenochirus curtipes, and Pseudhymenochirus merlini. Direct measurements of buccal cavity pressure during prey capture recorded localized pressure changes. […]
A combined analysis of variation in skull shape and feeding kinematics in five turtle species
Meeting Abstract 30.4 Jan. 5 A combined analysis of variation in skull shape and feeding kinematics in five turtle species STAYTON, C.T.; Bucknell University tstayton@bucknell.edu Organismal morphology and kinematics interact to produce complex behaviors; however, morphological and kinematic data have traditionally been analyzed separately using different techniques. Here, I present a joint study of the morphology and […]
Timing of birth affects body protein dynamics of mothers in an arctic mammal
Meeting Abstract 29.1 Jan. 5 Timing of birth affects body protein dynamics of mothers in an arctic mammal BARBOZA, P.S.*; PARKER, K.L.; Univ. of Alaska, Fairbanks; Univ. of Northern British Columbia ffpsb@uaf.edu Rapid changes in climate are altering the timing and abundance of food for seasonal reproduction in arctic animals. Reindeer and caribou typically form large herds […]
