WITT, T.L.*; MENZE, M.A.; HAND, S.C.; Louisiana State University, Baton Rouge: Isolation and Characterization of AMP-activated Protein Kinase from Embryos of Artemia franciscana Metabolic depression during diapause in embryos of the brine shrimp, A. franciscana, is characterized by a high AMP:ATP ratio. AMP-activated protein kinase (AMPK) is known to act as an ultra sensitive sensor […]

SCHROCK, SE*; YOUNG, RC; KETTERSON, ED; Indiana Univ., Bloomington; Indiana Univ., Bloomington; Indiana Univ., Bloomington: Is the aggressive response of captive female dark-eyed juncos to repeated intrusions mediated by testosterone? Hormonal mediation of intrasexual aggression has received less attention in females than in males. In some bird species, testosterone (T) has been suggested as a […]

RODRIGUEZ, A.*; KELLY, R.P.; EERNISSE, D.J.; California State Univ., Fullerton; Columbia Univ. and American Museum of Natural History; California State Univ., Fullerton: Is the Palos Verdes peninsula a barrier to gene flow for chitons and limpets? The comparative phylogeography of selected chiton and limpet species was analyzed in order to test a recent hypothesis that […]

POWELL, MP*; WATTS, SA; HENRY, RP; Univ Alabama at Birmingham; Univ Alabama at Birmingham; Auburn Univ: Inhibition of branchial carbonic anhydrase induction in the euryhaline blue crab, Callinectes sapidus, by a repressor in the sinus gland Blue crabs are euryhaline, being able to survive from 35 to 0 ppt salinity by regulating the osmotic concentration […]

RATHBURN, C.K.**; MACEY, B.M.; BURNETT, L.E.; BURNETT, K.G.; College of Charleston: Influence of a Previous Exposure to Vibrio campbellii on the Immune Response of the Blue Crab, Callinectus sapidus By 1 h following the injection of live Vibrio campbellii into blue crabs, culturable bacteria are eliminated from the hemolymph and circulating hemocyte numbers decline. We […]

BAKER, P.J.*; COSTANZO , J.P.; LEE, R.E.; Miami University; Miami University; Miami University: Induction of Oxidative Stress in a Terrestrially-Hibernating Turtle Hatchlings of the painted turtle, Chrysemys picta, hibernate terrestrially and may survive subfreezing temperatures by supercooling or by tolerating the freezing of their tissues. Previous research on this species has focused on the physiological […]

KURZE, E/M*; KERSHNER, J; ADAMS, N/L; California Polytechnic State University, San Luis Obispo: In situ solar ultraviolet radiation delays development of sea urchin embryos Strongylocentrotus purpuratus Ultraviolet radiation (UVR) causes delays in cell division and abnormal development of sea urchin embryos. We examined effects of solar UVR on development of embryos of the purple sea […]
