PEMBERTON, A. J.; BISHOP, J. D. D.; Marine Biological Association of the UK; Marine Biological Association of the UK: Factors affecting fission in a colonial ascidian Colony fission is an integral part of the life history of many modular organisms, allowing a single gentic individual to exist as two or more spatially discrete sub-colonies. This […]

RAMOS, DM; MONTEIRO, A; SUNY Buffalo; SUNY Buffalo: Eyespot development in Bicyclus anynana: Investigating the regulation and function of the transcription factor engrailed Butterfly eyespots have become a popular model system for the study of evolution and development. In 2001, Brunetti et al used antibody stainings to provide strong correlational evidence for the involvement of […]

WU, Su-Hua; LEE, Chi-Ying; National Changhua University of Education, Changhua, Taiwan, R.O.C; National Changhua University of Education, Changhua, Taiwan, R.O.C: Expression of crustacean hyperglycemic hormones in the hemocytes of the crayfish Procambarus clarkii Crustacean hyperglycemic hormone (CHH) is a neurohormone originally identified in the X-organ sinus gland (XO-SG) of the eyestalk ganglia and primarily involved […]

KUHN, C.E.*; COSTA, D; Univ. of California, Santa Cruz: Examination of the foraging strategies of a top marine predator: the California sea lion Studies of the foraging behavior of marine predators have primarily been limited to investigations of diet from stomach content or scat analysis. While this provides useful information on foraging at the population […]

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 […]

GOMEZ, A.M.*; LEE, K.J.; CHANG, E.S.; MYKLES, D.L.; Colorado State University, Fort Collins; Colorado State University, Fort Collins; Bodega Bay Marine Lab, Bodega Bay, CA; Colorado State University, Fort Collins: Establishment of an in vitro Y-Organ Assay to Investigate the Molt Inhibiting Hormone Signaling Pathway Ecdysis, commonly known as molting, is a process crustaceans must […]

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 […]

PECHENIK, J. A.; PEARSE, J. S.; QIAN, P.-Y.; Tufts University, Medford, MA; Univ. of California, Santa Cruz; Hong Kong Univ. of Science and Tech., China: Effects of low salinity on spawning, fertilization, and early development in the externally fertilizing polychaete Hydroides elegans: development is more sensitive than fertilization. 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 […]
