Meeting Abstract P3.39 Jan. 6 Modeling Muscle-skeleton Interaction in Early Vertebrates ARMAH, George*; CREED, Ross; CUI, Shiliang; QIAN, Jinjin; ROOT, Robert G.; Lafayette College; Lafayette College; Lafayette College; Lafayette College; Lafayette College robroot@lafayette.edu We propose that the evolution of vertebrae results at least in part from improved performance of a fish during a fast start. In particular, […]

Modeling Experiments on Pacemaker Interactions in Scyphomedusae
Meeting Abstract P3.69 Jan. 6 Modeling Experiments on Pacemaker Interactions in Scyphomedusae HAYWARD, R.T.*; SATTERLIE, R.A.; NOLAN, T.G.; University of North Carolina Wilmington; University of North Carolina Wilmington; State University of New York rth2850@uncw.edu Scyphozoan jellyfish are free-swimming gelatinous organisms whose nervous system includes a motor nerve net that controls swimming. Swim contractions originate in a network […]
Misunderstanding the Unambiguous Student Misconceptions in Phylogenetic Systematics
Meeting Abstract P3.101 Jan. 6 Misunderstanding the Unambiguous: Student Misconceptions in Phylogenetic Systematics BEI, D*; HOESE, WJ; California State University, Fullerton; California State University, Fullerton dbei@fullerton.edu According to Hennig, one goal of phylogenetic systematics is to express the relationships of all organisms in a form that cannot be misunderstood. Cladograms are unambiguous diagrams of hypothetical relationships among […]
Metabolic cost and power requirements of maximal labriform swimming in bluegill sunfish (Lepomis macrochirus)
Meeting Abstract P3.67 Jan. 6 Metabolic cost and power requirements of maximal labriform swimming in bluegill sunfish (Lepomis macrochirus). JONES, E.A.*; LUCEY, K.S.; ELLERBY, D.J.; Wellesley College; Wellesley College; Wellesley College dellerby@wellesley.edu At low swimming speeds bluegill sunfish swim in the labriform mode, generating lift and thrust by beating their pectoral fins. We measured the fin kinematics […]
Mechanics of Bipedal and Quadrupedal Running in the Desert Iguana
Meeting Abstract P3.54 Jan. 6 Mechanics of Bipedal and Quadrupedal Running in the Desert Iguana LACOUNT, L.T.*; BOROK, M.J.; AHN, A.N.; Harvey Mudd College; Harvey Mudd College; Harvey Mudd College aahn@hmc.edu Desert iguanas (Dipsosaurus dorsalis) have the relatively rare ability to run well both bipedally and quadrupedally. However, the reason why lizards sometimes run bipedally is still […]
Mechanical power output of the pectoral fin abductor and adductor muscles of the bluegill sunfish (Lepomis macrochirus)
Meeting Abstract P3.66 Jan. 6 Mechanical power output of the pectoral fin abductor and adductor muscles of the bluegill sunfish (Lepomis macrochirus). LUCEY, K.S.*; JONES, E.A.; ELLERBY, D.J.; Wellesley College; Wellesley College; Wellesley College dellerby@wellesley.edu Bluegill sunfish swim in the labriform mode at low swimming speeds, generating lift and thrust by beating their pectoral fins. The range […]

Localization and metabolism of calcium in developing scleractinian coral
Meeting Abstract P3.8 Jan. 6 Localization and metabolism of calcium in developing scleractinian coral ROGERS-LOWERY, CL*; SZMANT, AM; Catawba College, Salisbury, NC; University of North Carolina Wilmington clowery@catawba.edu The calicoblastic epithelium of scleractinian coral secretes the calcium carbonate skeleton that forms massive reefs. This process involves the use of channels and pumps to translocate calcium, bicarbonate, and […]
Juvenile hormone controls the timing of oviposition independent of the storage threshold in lubber grasshoppers
Meeting Abstract P3.138 Jan. 6 Juvenile hormone controls the timing of oviposition independent of the storage threshold in lubber grasshoppers FRONSTIN, RB; HATLE, JD*; Univ. of North Florida; Univ. of North Florida jhatle@unf.edu Storage thresholds have been theorized to be important for major life history transitions. These theories hold that sufficient nutrients must be stored to fuel […]
