Comparison Of The DNA Methylation Patterns Between Interspecific Xenopus F1 Hybrids And Their Parental Species
(Biology, 2011-07-14)
In this study the main focus is to compare the methylation patterns of interspecific Xenopus F1 hybrids to the parental species using Methyl-Sensitive Amplification Polymorphisms (MSAPs). Genomic DNA was extracted from the ...
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 ...
Intra-specific Variation Across A Small Temperature Difference In The Spider Rabidosa rabida (Araneae: Lycosidae) From The Mountains In Arkansas
(Biology, 2011-07-14)
Temperature affects all levels of biological organization and ultimately affects multiple aspects of ecological performance and fitness. Generalist arthropod predators are ectothermic and are strongly affected by temperature ...
Bioinformatic Identification Of Small RNA (and Their Targets) In The Testis Of Clawed Frogs (Xenopus And Silurana): Implications For Male Fertility
(Biology, 2012-04-11)
Chapter one sets the stage for this project, which lies somewhere near the intersection of speciation, genome, and reproductive biology. Chapter two identifies miRNA with shared expression profiles (Silurana and Xenopus). ...
Nematodes With Three Genders: Models For The Evolution Of Mating Systems, Parasitism And Aging
(Biology, 2013-10-23)
All living organisms reproduce and age. These are the two basic facets of life, but in many aspects poorly understood. The majority of the species are male/female. The proportion of genders in population can vary significantly ...
Phylogenetic Systematics, Population Genetics, And The Evolution Of Color Pattern Polymorphism And Coralsnake Mimicry In The Snake Genus Sonora
(Biology, 2013-03-20)
Mimicry is a widespread biological phenomenon and is simply defined as the resemblance of one organism to another for some sort of protective purpose. Specifically, Batesian mimicry occurs when a harmless species imitates ...
Insights Into The Transmission Of Helitrons And Their Impact On The Genome Architecture Of Myotis Lucifugus, The Little Brown Bat
(Biology, 2011-03-03)
Probably the most dynamic proportion of multicellular eukaryotic genomes is composed of teeming populations of parasitic mobile DNA, called transposable elements (TEs). Helitrons are rolling circle TEs that have a limited ...
Phylogenetic Relationships And Feeding Behavior Of Neotropical Snail-eating Snakes (Dipsadinae, Dipsadini)
(Biology, 2013-03-20)
The snake subfamily Dipsadinae contains more than 350 ecologically diverse species in about 32 genera. Members of the tribe Dipsadini are gastropod specialists, and many possess a suite of adaptations for eating snails. ...
