Meeting Abstract S1-3 Saturday, Jan. 4 08:30 – 09:00 Advances in the use of biogeochemical markers to track the diets and movement of Antarctic marine predators POLITO, MJ*; MICHELSON, CI; MCMAHON, KW; Louisiana State University; Louisiana State University; University of Rhode Island mpolito@lsu.edu http://www.oceanography.lsu.edu/politolab/ Quantifying the diets, foraging ecology, and at-sea distribution of wide-ranging marine predators is […]
Thermal dose and embryonic sex determination in Chelydra serpentina
LOTT,D.B.; ACKERMAN,R.A.*: Thermal dose and embryonic sex determination in Chelydra serpentina. The thermal dose (degree hours) necessary to determine the sex of Chelydra serpentina embryos was assessed over two nesting seasons (1996,1997) using programmable incubators. A total of 48 clutches from Iowa, Illinois, Minnesota and Louisiana were divided among treatments and among experimental boxes within […]
Maximum titers of vitellogenin and storage protein occur during the canalized phase of grasshopper oogensis
HATLE, J.D.*; BORST, D.W.; ESKEW, M.R.; JULIANO, S.A.: Maximum titers of vitellogenin and storage protein occur during the canalized phase of grasshopper oogensis Many organisms meet the challenge of unpredictable environmental conditions by remaining developmentally flexible early in their development and only later enter a canalized (inflexible) phase of development. Our ultimate goal is to […]
Lead analysis of snapping turtle (Chelydra serpentina) hatchlings exposed to lead nitrate at various times during incubation
Rimkus, T.A.*; Siebert, C.A.; Selby, D.M.: Lead analysis of snapping turtle (Chelydra serpentina) hatchlings exposed to lead nitrate at various times during incubation. Eggs from three female snapping turtles were incubated in sand with a water content of 4% by mass. This is equivalent to being exposed to a water potential of -7 kPa. Three […]
Experimental and Demographic Analyses of Growth and Sexual Size Dimorphism in a Lizard, Sceloporus undulatus
JOHN-ALDER, H.B.*; HAENEL, G.J.: Experimental and Demographic Analyses of Growth and Sexual Size Dimorphism in a Lizard, Sceloporus undulatus Sexual size dimorphism (SSD) is a common phenomenon caused by a variety of environmental and genetic mechanisms in animals. In the current study, we investigate the demography of a population of eastern fence lizards (Sceloporus undulatus) […]
Body size evolution in a laboratory strain of Manduca sexta Implications for studies in insect physiology and endocrinology
D’AMICO, L.J.*; DAVIDOWITZ, G.; NIJHOUT, H.F.: Body size evolution in a laboratory strain of Manduca sexta : Implications for studies in insect physiology and endocrinology The tobacco hornworm, Manduca sexta, has been used as a model organism for the study of insect developmental physiology and endocrinology for more than 30 years. Many of the connections […]
The study of shrimp CHHMIHGIH gene family gene structure, expression and biological assay of recombinant neuropeptides
CHAN, S.-M.; GU, P.-L.: The study of shrimp CHH/MIH/GIH gene family: gene structure, expression and biological assay of recombinant neuropeptides The crustacean CHH/MIH/GIH neuropeptide family constitutes a group of important hormone that regulates important processes such as molting, glucose metabolism and reproduction. The characterization of these neuropeptides has attracted much attention due to their potential […]
The effects of sinus gland extracts on transcript levels of farnesoic acid O-methyl transferase (MeT) in the lobster mandibular organ
HOLFORD, K.C.*; BORST, D.W.: The effects of sinus gland extracts on transcript levels of farnesoic acid O-methyl transferase (MeT) in the lobster mandibular organ. Methyl farnesoate (MF) appears to have important roles in the regulation of crustacean reproduction, molting, and behavior. In decapod crustaceans, the mandibular organ (MO) is the principle site of MF synthesis […]
