NAKANISHI, N; CAMARA, A/C; JACOBS, D/K; UCLA; UCLA; UCLA: Evolution of sensory genes in basal Metazoa Homeodomain genes involved in sensory and neural differentiation form basal branches of homeodomain gene trees, indicating that these genes evolved early and are present in basal Metazoa. Substantiating this claim, we previously reported the recovery of sensory-specific homeodomains sine […]

LIU, C*; GIBB, A.C.; Northern Arizona University; Northern Arizona University: Embryonic development and escape behavior in Oncorhynchus mykiss Rainbow trout, Oncorhynchus mykiss, embryos hatch from the egg with a large yolk mass and in an advanced state of morphological development. Our previous research has shown that O. mykiss embryos are very coordinated immediately after hatching […]

KAVANAGH, K.D.*; SALAZAR-CUIDAD, I.; JERNVALL, J.; Univ. of Helsinki, Finland; Univ. of Helsinki, Finland; Univ. of Helsinki, Finland: Embryonic Mouse “Braces” Test the Morphodynamic Model of Tooth Evolution The Morphodynamic Model (Salazar-Cuidad et al., 2003) predicts that shape changes alone could affect the signaling dynamics in the gene networks controlling morphogenesis of the tooth. This […]

Populations of Hydroides elegans in Hong Kong […]

KABANGE, Zaina / S; HEWS, Diana / K; Indiana State University, Terre Haute; Indiana State University, Terre Haute: Effects of Testosterone and Immune Challenge on White Blood Cell Counts in Male Sceloporus undulatus Lizards Testosterone affects behavior and morphological traits important in sexual selection. Testosterone also plays a role in the development and functioning of […]

SIEG, A/E; SPOTILA, J/R; BINCKLEY, C/A; PALADINO, F/V; Drexel University; Drexel University; Old Dominion; Indiana Purdue, Fort Wayne: Effects of Ambient Temperature and Precipitation on Inferred Sex Ratios for Leatherback Sea Turtle Nests at Playa Grande, Costa Rica Temperature is an abiotic factor that has been well-documented in its effects on sea turtle nests�especially in […]

SPENCER, R-J; JANZEN, F.J.; Iowa State University: Ecology and evolution of TSD in turtles: The value of long-term research and the effects of climate change. Sex in many reptiles is determined permanently by environmental temperatures experienced during embryonic development. The unusual nature of this sex-determining system, with its potential to produce strongly-biased sex ratios, has […]
