Phenotypic plasticity and the evolutionary diversification of plant sexual systems
Meeting Abstract S9-1.2 Saturday, Jan. 7 Phenotypic plasticity and the evolutionary diversification of plant sexual systems. DIGGLE, PK; University of Colorado/Harvard University diggle@fas.harvard.edu Andromonoecy, a sexual system in which individuals bear both hermaphroditic (bisexual) and male flowers, has evolved independently in numerous plant lineages, yet the advantages of this system remain poorly understood. I will report on […]
Origin, Evolution & Development of the Chordates Notochord gain or retention
Meeting Abstract S9-1.3 Saturday, Jan. 7 Origin, Evolution & Development of the Chordates: Notochord gain or retention? SWALLA, B.J.*; Univ. of Washington bjswalla@u.washington.edu Hemichordates and echinoderms are crucial for understanding the evolution of the vertebrate central nervous system (CNS), deuterostome evolution and chordate origins. Hemichordates share many chordate features, including a post-anal tail, gill slits, and a […]
Evolutionary inferences from transcriptional analysis of wild and domesticated tomato
Meeting Abstract S9-1.5 Saturday, Jan. 7 Evolutionary inferences from transcriptional analysis of wild and domesticated tomato SINHA, N R; Univ. of California, Davis nrsinha@ucdavis.edu The domestication of crop species from wild relatives altered human history, while human intervention simultaneously modified the form, physiology, and life history of the domesticated plant species. The process of domestication thus provides […]
The nature of nurture and the causes of traits toward a comprehensive theory of developmental evolution
Meeting Abstract S8-2.4 Friday, Jan. 6 The nature of nurture and the causes of traits: toward a comprehensive theory of developmental evolution MOCZEK, Armin; Indiana University Bloomington armin@indiana.edu This presentation has three parts. First, I posit that much research in contemporary evolutionary and developmental biology, including efforts focused on developmental plasticity, remains steeped in a traditional framework […]
The making of a social insect – Genetics of Social Design
Meeting Abstract S8-2.2 Friday, Jan. 6 The making of a social insect – Genetics of Social Design AMDAM, GV; Arizona State University Gro.Amdam@asu.edu How do complex social systems evolve? What are the evolutionary and developmental building blocks of division of labor and specialization, the hallmarks of insect societies? In solitary insects, shifts during life history between reproductively […]
Genetic Contingency Intergrating genetic background and environment into the study of mutational effects
Meeting Abstract S8-2.1 Friday, Jan. 6 Genetic Contingency: Intergrating genetic background and environment into the study of mutational effects. DWORKIN, Ian; Michigan State University idworkin@msu.edu In genetic analysis, it is well known that the observed phenotype is not only a function of a given mutation, but also the influences of the genetic background in which it occurs, […]
Evolutionary consequences of context-dependent maternal effects
Meeting Abstract S8-2.3 Friday, Jan. 6 Evolutionary consequences of context-dependent maternal effects CRUICKSHANK, Tami; National Evolutionary Synthesis Center tami.cruickshank@gmail.com Context-dependent maternal effects are common; environmental variation among dams may be reflected in distributions of offspring phenotypes. I examine the evolutionary genetic consequences of plasticity due to maternal effects, focusing on properties that are unique compared with within-generational […]
Relaxed selection on rates of molecular evolution consequence or cause of phenotypic plasticity
Meeting Abstract S8-1.2 Friday, Jan. 6 Relaxed selection on rates of molecular evolution: consequence or cause of phenotypic plasticity? LEICHTY, A. R.; PFENNIG, D. W.*; JONES, C. R.; PFENNIG, K. S.; University of Pennsylvania; University of North Carolina, Chapel Hill; University of North Carolina, Chapel Hill; University of North Carolina, Chapel Hill dpfennig@unc.edu Phenotypic plasticity––the capacity of […]
Plasticity and the integrated phenotype examination of integration through development and across environments through classic and genomic approaches
Meeting Abstract S8-1.6 Friday, Jan. 6 Plasticity and the integrated phenotype: examination of integration through development and across environments through classic and genomic approaches MURREN, Courtney J.*; MESSERVY, Jason; STRAND, Allan E.; RUTTER, Matt T.; College of Charleston murrenc@cofc.edu Suites of complex characters that work together can be defined as functional modules. Organisms having strong relationships among […]
