LIGON, D.B.*; LOVERN, M.B.; Oklahoma State University; Oklahoma State University: Maternal, Sex and Incubation Temperature Effects on an Endangered Tortoise, Geochelone sulcata Embryonic and neonatal phenotypes are affected by a number of factors such as genotype, maternal investment and environmental conditions during development. Because of its role in determining sex in many turtle species, effects […]

LOURDAIS, Olivier; DENARDO, Dale F.*; HOFFMAN, Ty C.M.; Arizona State Univeristy; Arizona State University; Arizona State University: Maternal brooding in the Children’s python (Antaresia childreni) promotes egg water balance Pythonine snakes show extended care of their clutches with maternal egg brooding. While brooding may provide the eggs thermal advantages via insulation and, in some species, […]

GILMAN, Casey*; WOLF, Blair; University of New Mexico: Lizards, eggs, and ultrasound: testing the efficacy of quantifying reproductive effort in squamate reptiles using portable ultrasonography. Most studies of reproductive effort in lizards have required that individuals be sacrificed to obtain population level data on life history traits such as clutch and egg size. While this […]

DODD, K.L.**; WIBBELS, T.; Univ. of Alabama, Birmingham; Univ. of Alabama, Birmingham: Clutch-specific Sensitivity to Estrogen in a Turtle with Temperature-dependent Sex Determination Most turtles exhibit temperature-dependent sex determination in which the incubation temperature of the egg determines the sex of the embryo. Previous studies have revealed clutch-specific variation in the pivotal temperature of sex […]

TERANISHI, Kristen S*; STILLMAN, Jonathon H; University of Hawaii at Manoa; Romberg Tiburon Center, San Francisco State University: Seasonal variation in hepatopancreas transcriptome profiles following heat stress in the porcelain crab, Petrolisthes cinctipes How organisms respond to thermal stress in their natural habitat is a function of thermal acclimatization state. Here, we have investigated seasonal […]

TRANT, J.M.; PLACE, A.R.*; Univ. of Maryland Biotechnology Institute, Baltimore; Univ. of Maryland Biotechnology Institute, Baltimore: Production and Analysis of Normalized cDNA Libraries from Blue Crab (Callinectes sapidus) Endocrine Tissues In order to protect and propagate economically important species of crustaceans (such as the Blue Crab), an understanding of the physiology of molting and reproduction […]

HEAD, JM*; TERWILLIGER, NB; Univ. of Oregon, OIMB: Crustacean Responses to Hypoxia: The Role of HIF-1&alpha. The habitats of aquatic crustaceans are highly variable with respect to conditions such as temperature, salinity, and oxygen tension. We are investigating the possible role of the hypoxia-dependent transcription factor, Hypoxia Inducible Factor-1 (HIF-1), in the response of crustaceans […]

CHUNG, J. Sook*; ZMORA, N.; ZOHAR, Y.; COMB, UMBI, Baltimore; COMB, UMBI, Baltimore; COMB, UMBI, Baltimore: Cloning and expression profile of non-eyestalk Crustacean hyperglycemic hormone (CHH) neuropeptides from the blue crab, Callinectes sapidus Since the first structural characterization of crustacean hyperglycemic hormone (CHH) from sinus gland of Carcinus maenas, other CHHs, showing with a high […]

CHAN, S.-M.; The University of Hong Kong: Vitellogenin and vitellogenesis in decapod crustaceans: knowledge from proteomic and molecular studies Vitellogenin (Vg) is the precursor for one of the major yolk proteins that supplies the embryos and larvae with nutrients for development and growth. During ovarian maturation of decapod crustaceans, vitellogenins are synthesized and transported to […]
