Functional Characterization Of A Putative Disaccharide Membrane Transporter In Crustacean Intestine, Rasheda S. Likely
Functional Characterization Of A Putative Disaccharide Membrane Transporter In Crustacean Intestine, Rasheda S. Likely
UNF Graduate Theses and Dissertations
The mechanisms of transepithelial absorption of dietary sucrose in the American lobster, Homarus americanus, were investigated in this study to determine whether sugars can be transported across an animal gut intact or as monosaccharides following hydrolysis. Lobster intestine was isolated and mounted in a perfusion chamber to characterize the mechanisms of mucosal to serosal (MS) 14C -sucrose transport across the intestine MS fluxes were measured by adding varying concentrations of 14C-sucrose to the perfusate which resulted in a hyperbolic curve following Michaelis-Menten kinetics. The kinetic constants of the proposed sucrose transporter were KM = 15.84 ± 1.81 …
Effect Of Feed Additives On Amino Acid And Dipeptide Transport By Intestines Of American Lobster And Atlantic White Shrimp, Maria Louise Peterson
Effect Of Feed Additives On Amino Acid And Dipeptide Transport By Intestines Of American Lobster And Atlantic White Shrimp, Maria Louise Peterson
UNF Graduate Theses and Dissertations
Previous nutritional physiology research using L-histidine and zinc in American lobster intestine (Homarus americanus) has suggested that these solutes can be co-transported as complexes (Histidine-Zinc-Histidine) across the intestine using a peptide transporter. Furthermore, transport of L-leucine was shown to be inhibited by high calcium concentrations. Dipeptide and bis-complex transport and the role of calcium were investigated in the perfused intestines of lobster and Atlantic white shrimp (Litopenaeus setiferus). Following trans-intestinal transport, serosal medium was analyzed for amino acid composition by gas chromatography. In lobster, the transport of glycylsarcosine (Gly-Sar) from mucosa to serosa was stimulated two-fold …

The Social Structure And Mating Strategies Of Bottlenose Dolphins (Tursiops Truncatus) In The St. Johns River, Jessica Lea Ermak
UNF Graduate Theses and Dissertations
Across populations, bottlenose dolphins (Tursiops sp.) exhibit a fission-fusion pattern of associations, in which group size and composition change fluidly throughout the day. Beneath this seemingly ephemeral social structure, considerable variation exists across study sites. While females typically have moderate bonds with one another within a large social network, male-male bonds are variable, though males typically take one of two strategies; some males encounter females individually for opportunities to breed while others cooperate within a first-order alliance to collectively herd females. In addition, multi-tiered alliances in which two first-order alliances cooperate to defend or assist in the theft of a …
