Distribution Of R-Banded Chromosome Variants In A Bottlenose Dolphin (Tursiops Truncatus) Population, Kristine Anne Gunter

Dissertations and Theses

When combined with observational and behavioral data, chromosome variant analysis provides a means of assessing population structure in bottlenose dolphins, Tursiops truncatus. In this cytogenetic analysis of thirty-six bottlenose dolphins, a distribution of fluorescent R-band variants was catalogued and used as a way to characterize the genetic structure of a Tursiops population inhabiting the Matagorda Bay, Texas, area. Three different population genetic analytical techniques were evaluated for their usefulness in analyzing cytogenetic data. The chromosome variant data obtained from this study was then compared with cytogenetic data gathered from a resident dolphin population residing near Sarasota, Florida.

Adsorption Of Ruthenium Red To Phospholipid Membranes, Pavel Smejtek, D. Voelker

Physics Faculty Publications and Presentations

We have measured the distribution of the hexavalent ruthenium red cation (RuR) between water and phospholipid membranes, have shown the critical importance of membrane negative surface charge for RuR binding, and determined the association constant of RuR for different phospholipid bilayers. The studies were performed with liposomes made of mixtures of zwitterionic L-alpha-phosphatidylcholine (PC), and one of the negatively charged phospholipids: L-alpha-phosphatidylserine (PS), L-alpha-phosphatidylinositol (PI), or L-alpha-phosphatidylglycerol (PG). Lipid composition of PC:PX membranes was 1:0, 19:1, 9:1, and 4:1. Liposomes were processed using freeze-and-thaw treatment, and their size distribution was characterized by light scattering and electron microscopy. Experimental distribution isotherms …
