The relationship between pleiotropy and evolvability
Meeting Abstract 37.11 Tuesday, Jan. 5 The relationship between pleiotropy and evolvability PAVLICEV, M.*; CHEVERUD, J. M.; HANSEN, T.F.; University of Oslo, Norway; Washington University, St. Louis, MO; University of Oslo, Norway pavlicev@pcg.wustl.edu The question of what kind of genetic architecture maximizes evolvability of the system is central to the evolution of complex organisms. Modularity of pleiotropic […]
Sexual Dimorphism Increases Evolvability in a Computational Model of a Genetic Regulatory Network
Meeting Abstract 37.10 Tuesday, Jan. 5 Sexual Dimorphism Increases Evolvability in a Computational Model of a Genetic Regulatory Network FIERST, Janna L; Florida State University jfierst@bio.fsu.edu The majority of work on genetic regulatory networks has focused around environmental and mutational robustness, and much less attention has been paid to the conditions under which a network may produce […]

Fine Scale Phylogeography of Sceloporus occidentalis) in the Transverse Ranges of California Reveals Coincidence with Geological Complexity
Meeting Abstract 37.9 Tuesday, Jan. 5 Fine Scale Phylogeography of Sceloporus occidentalis) in the Transverse Ranges of California Reveals Coincidence with Geological Complexity ARCHIE, James W*; QUIJANO, Marc Oliver; California State Univ., Long Beach jarchie@csulb.edu The Transverse and South Coastal Ranges of California have undergone complex geological changes affecting resident taxa. The Transverse Santa Inez Range originated […]
Demographic history and ecological connectivity of the scalloped hammerhead shark, Sphyrna lewini, in the Eastern Pacific
Meeting Abstract 37.6 Tuesday, Jan. 5 Demographic history and ecological connectivity of the scalloped hammerhead shark, Sphyrna lewini, in the Eastern Pacific NANCE, Holly/A*; MARKO, Peter/B; Clemson University; Clemson University hnance@clemson.edu Describing basic migration rates and patterns of large, marine predators is challenging, yet necessary for species that are overfished and at risk of extinction. To that […]
