The effects of predatory lizards on limb-morphology evolution in side-blotched lizards, Uta stansburiana
Meeting Abstract 15.1 Saturday, Jan. 4 10:30 The effects of predatory lizards on limb-morphology evolution in side-blotched lizards, Uta stansburiana BULA, PA; ZANI, PA*; University of Wisconsin-Stevens Point; University of Wisconsin-Stevens Point pzani@uwsp.edu Since Arnold (1983) introduced the ecomorphological paradigm numerous studies have demonstrated clear morphology-performance links. However, less clear are the ecological patterns stemming from morphotype-performance-fitness […]

The molecular and morphological development […]
Does Nuclear Transport Influence Neurogenesis in Sea Urchin Embryos
Meeting Abstract 15.2 Sunday, Jan. 4 10:30 Does Nuclear Transport Influence Neurogenesis in Sea Urchin Embryos? BYRUM, CA*; SMITH, J; EASTERLING, MR; BRIDGES, MC; College of Charleston byrumc@cofc.edu http://biology.cofc.edu/about-the-department/faculty-staff-listing/byrum-christine.php In eukaryotes, karyopherin-alpha (KPNA) importins assist in transfer of transcription factors and other molecules into the nucleus. It has become increasingly evident that learning more about KPNAs may […]
Development and growth of the rostrum lateral line system in paddlefish (Polyodon spathula)
Meeting Abstract 15.1 Sunday, Jan. 4 10:15 Development and growth of the rostrum lateral line system in paddlefish (Polyodon spathula) ROBERTSON, J.C.; Westminster College (PA) robertjc@westminster.edu Several weeks after hatching, larval paddlefish begin to grow a rostrum; within a period of several more weeks, this extension of the cranium has grown to represent one-third of the total […]
