Meeting Abstract S1-2.2  Thursday, Jan. 3  The Thyroid-Gonad axis: Insights on a novel mechanism of communication in the American Alligator BERMUDEZ, DS*; GUILLETTE, LJ; University of Florida dieldrich@gmail.com Thyroid hormones are known to have a cooperative role in gonadal development and function. There is a growing body of work demonstrating that thyroid hormones play a crucial role […]

Meeting Abstract S1-2.3  Thursday, Jan. 3  Moving towards many-marker datasets: progress and challenges for turtle phylogenetics THOMSON, R.C.*; SHAFFER, H.B.; Univ. of California, Davis; Univ. of California, Davis rcthomson@ucdavis.edu The field of systematics has seen rapid progress in applying molecular tools to the study of phylogeny, both at the species level and at deeper nodes in the […]

Meeting Abstract S1-2.1  Thursday, Jan. 3  Exploiting Genomic Resources in Studies of Speciation and Adaptive Radiation of Anolis Lizards. SCHNEIDER, Christopher; Boston University cschneid@bu.edu Lizards of the genus Anolis have radiated extensively within and among islands in the Caribbean. Here I provide a prospectus and preliminary data on the genetics of features important in anoline diversification and […]

Meeting Abstract S1-2.4  Thursday, Jan. 3  Evolution of the gene regulatory network underlying sexual differentiation in turtles with alternative sex determining mechanisms NICOLE, Valenzuela; Iowa State University nvalenzu@iastate.edu The evolution of sex determining mechanisms has fascinated biologists and laymen alike. Sex determination has paramount consequences for the evolution of a multitude of traits, from sex allocation to […]

Meeting Abstract S1-1.3  Thursday, Jan. 3  The Functional Evolution of Steroid Hormone Receptors: Insights from Reptiles KOHNO, Satomi*; KATSU, Yoshinao; IGUCHI, Taisen; GUILLETTE, Louis J Jr; University of Florida; National Institute of Basic Biology; National Institute of Basic Biology; University of Florida kohno@zoo.ufl.edu Steroid hormones are essential for the normal function of most organ systems in vertebrates. […]

Meeting Abstract S1-1.6  Thursday, Jan. 3  Rate of chromosome changes and speciation in reptiles OLMO, Ettore; Universita Politecnica delle Marche. e.olmo@univpm.it The chromosome changing rate was studied in 1329 species of reptiles in order to evaluate the karyological evolutionary trend and a possible correlation between chromosome mutations and some aspects of the evolution of the class. The […]

Meeting Abstract S1-1.5  Thursday, Jan. 3  Maternally derived yolk steroid hormones in TSD reptiles: A comparison among species and their possible roles in embryonic development ELF, P; University of Minnesota Crookston pelf@umn.edu Maternally produced hormones deposited in yolk material have been implicated in the sex determination process in oviparous reptiles with temperature-dependent sex determination (TSD). We have […]

Meeting Abstract S1-1.7  Thursday, Jan. 3  Genome Architecture and Diversity in Reptiles ORGAN, Chris*; EDWARDS, Scott; Harvard University corgan@oeb.harvard.edu Characterization of reptile (sauropsid) genomes is essential for understanding the overall diversity and evolution of amniote genomes because they constitute a major fraction of the amniote evolutionary tree. In addition, the study of reptile genomics provides the evolutionary […]

Meeting Abstract S1-1.4  Thursday, Jan. 3  Comparative expression and genomic organization of sex-differentiating genes in a bird and a reptile JANES, D.E.*; EDWARDS, S.V.; Harvard University; Harvard University djanes@oeb.harvard.edu Although sex-determining mechanism differs between birds and some reptiles, several genes associated with sex differentiation are found in both groups. For example, American Alligators do not have heteromorphic […]

Meeting Abstract S1-1.2  Thursday, Jan. 3  Challenges and opportunities in comparative reptilian genomics GLENN, Travis C.*; JONES, Kenneth L.; SAWYER, Roger H.; GREENWOLD, Matthew J.; CRAWFORD, Nicholas G.; Universities of Georgia & South Carolina; University of Georgia; University of South Carolina; University of South Carolina; Boston University glenn@srel.edu Reptiles are the sister group to mammals and thus […]
