Thermal Tolerance, Physiologic Condition, And Population Genetics Of Dreissenid Mussels (Dreissena polymorpha and D. rostriformis bugensis) Relative To Their Invasion Of Waters In The Western United States
(Biology, 2010-03-03)
Zebra mussels, Dreissena polymorpha, and quagga mussels, D. rostriformis bugensis, Eurasian freshwater bivalves, invaded the North American (NA) Great Lakes in the mid 1980's. Subsequently, they invaded water bodies east ...
Diversity And Community Organization In The Periphyton Of Recirculating Streams Channels Are Defined By Current Velocity And Nutrient Supply
(Biology, 2010-03-03)
In a series of experiments taking place in recirculating artificial stream channels, periphyton communities growing on ceramic tiles were subjected to variations in current velocity and nutrient supply. The first experiment ...
Theoretical And Practical Utility Of Gene Sequences in Phylogenetic and Phylogeographic Analysis
(Biology, 2010-03-03)
Phylogenetics, or the study of evolutionary relationships among organisms, is a rapidly changing field due primarily to the dramatic increase in available molecular characters and increasingly sophisticated theoretical and ...
Reproductive Isolation In Drosophila: From Behavior To Genome
(Biology, 2010-11-01)
In this study, I investigate factors underlying reproductive isolation in Drosophila. I begin (Part I) by measuring behavioral isolation between Zimbabwe and cosmopolitan D. melanogaster, and asking the following questions: ...
Analysis Of The Suppressive Effects By Reovirus On Rotavirus Replication During Co-infections
(Biology, 2010-11-01)
Reovirus and rotavirus are both members of the Reoviridae family and commonly occur in children. Rotavirus induced diarrhea is one of the leading causes of death in children under the age of five worldwide. Identifying ...
Characterization Of Anti-rotavirus Activities Of Saponin Extracts From Quillaja Saponaria
(Biology, 2010-11-01)
Rotavirus is the leading cause of severe diarrhea disease in newborns and young children worldwide, estimated to be responsible for over 500,000 adolescent deaths mostly in developing countries each year. Rotavirus-related ...
Explorations Of Aspects Of Mixotrophy Using Mathematical Models
(Biology, 2010-11-01)
This work examined three theoretical aspects of mixotrophy, the simultaneous use of phototrophic and heterotrophic nutritional modes, and one practical application. The first study addressed the coexistence of microorganisms ...
Effects Of The Exotic Invader, Tamarix spp., On Aspects Of The Aquatic Ecosystem At McComb Creek, Presidio County, Texas
(Biology, 2010-07-19)
The effects of saltcedar, Tamarix spp., invasion in riparian zones of the western United States have been well documented. These include, but are not limited to soil salinization, and shifts in hydrology and water use. ...
The Herpetofauna Of The Virunga Mountains With Emphasis On Two Species of Albertine Rift Endemic Treefrogs Of The Genus Leptopelis.
(Biology, 2010-07-19)
I present a short description of the biodiversity crisis, the Albertine Rift as a biodiversity hotspot, and a literature review of the taxonomy of the genus Leptopelis. I then present a list of the reptiles and anurans ...
