Itzick Vatnick*; Bruce Grant: Principles of Design for a Research-Centered Biology Curriculum In the last decade, undergraduate science education has undergone a quiet revolution emphasizing opportunities for student-directed original inquiry as the curriculum. Opportunities to conduct genuine investigations are important because they teach students how science is actually done and thereby they learn by doing […]

O’REILLY, J.C.*; KLEY, N.J.; RICHMOND, A.M.; BRAINERD, E.L.: Prey Capture Kinematics in Chelus fimbriatus (Testudines: Pleurodira) Many aquatic turtles can successfully capture elusive aquatic prey but few, if any, approach the abilities of the South American matamata (Chelus fimbriatus). The goal of this project is to use high-speed videography, fluoroscopy and anatomical dissection to gain […]

Ashraf, M.; Nesbitt, R. A.; Lee, C.* M.*: Positioning of Kinetoplasts in Trypanosoma musculi and Trypanosoma lewisi During the Development in-vitro ABSTRACT: Trypanosoma musculi is parasitic to mice and Trypanosoma lewisi is parasitic to rats, and both of these parasites are highly specific to their hosts. The development of Trypanosoma musculi and Trypanosoma lewisi were […]

RICHARDSON, J.F.*; ERNST, H.H.; SATTERLIE, R.A.: Pleural Ganglion Asymmetry in the Sexually Immature and Mature Pteropod Mollusc, Clione limacina In immature specimens of the pteropod mollusk Clione limacina, the right pleural ganglion is slightly larger than the left. The average diameter of the former is 180um, while that of the latter is 160um. The right-to-left […]

SUMMERS, A.P.; ROWE, T.; KETCHAM, R.A.: Ontogeny of the hornshark chondrocranium and the evolution of trabecular cartilage The skeleton of the sharks, rays, and chimaeroids is composed of cartilage, some of which is calcified. The vertebrae are completely calcified, while the remainder of the skeleton has one or more thin layers of calcified blocks (tesserae) […]

MARSHALL, C.D.*; HERRING, S.W.: Motor Control of Perioral Muscles: Somatotopic Organization in the Pig Facial Nucleus. The lips and cheeks of mammals form a complex structure of constant volume that appears to function as a muscular hydrostat. The muscles involved, primarily orbicularis oris and buccinator, are part of the facial musculature innervated by CN VII. […]

McALEER, M. W.*; GIRARD, I.; RHODES, J. S.; GARLAND, JR., T.: Motivation of House Mice Artificially Selected for High Wheel Running We have conducted an artificial selection experiment in which 4 replicate lines of house mice were bred for high wheel running and 4 non-selected lines were maintained as controls. At generation 24, mice from […]

WILMOT, A.*; DIDIER, D.; WEBB, J.: Morphology of the Lateral Line Canals of the Head in Chimaerid Fishes (Family Chimaeridae) Most living chimaeroid fishes have a unique lateral line canal system consisting of open canals that appear as grooves on the head and trunk. Members of the Family Chimaeridae possess a unique canal morphology in […]

SHARDO, J.D.*; GRANDE, T.: Morphology and Development of the Postcranial Axial Skeleton of the American Shad, Alosa sapidissima The morphology and ontogeny of the postcranial skeleton were studied in three developmental series and a number of postmetamorphic specimens of American shad, equaling more than 180 specimens. Specimens were cleared and stained with alcian blue to […]

BECK, A.L.*; BLOB, R.W.; HOPSON, J.A.: Morphological indicators of sprawling and non-sprawling limb posture in tetrapods. Determination of locomotor postures in fossil tetrapods is difficult because their behavior cannot be observed directly. To evaluate morphological indicators of limb posture that could be used to interpret stance in extinct tetrapods, we have used multivariate statistical analyses […]
