Molecular Characterization of Early Dedifferentiation in Newt Forelimb Regeneration
Newts have the incredible ability to regenerate many different organs and tissues as adults, including the limbs. Limb regeneration occurs via the dedifferentiation of stump tissue and the formation of a blastema, which provides the majority of cells for the regenerate. Despite all that we have …

Trypanosoma barbari, a new species from the newt Triturus torosus
… of' obtaining specimens of this Pacific Coast newt, and of the eight animals examined six were parasitized. Contrary to the primary observations, evidence was accumulated which proved beyond any doubt that the flagellate is polymorphic and that, evidently, it has not been reported or described. …

Cloning of actin genes from a genomic library of the newt, Notophthalmus viridescens
… developmentally regulated genes from a newt genomic library for use in future studies of gene expression during limb regeneration. We decided to clone the cytoskeletal actin gene for the following reasons: 1. its expression reflects the proliferative and differentiatlve states of cells …

Microhabitat requirements of the great crested newt (<i>Triturus cristatus</i>) in a woodland area
The great crested newt Triturus cristatus is one of Europe's fastest declining amphibian species. This thesis aimed to increase our knowledge of the microhabitat use and ecology of great crested newts within a woodland area in the British Isles and suggest ways of improving measures for …

Purification of A Serum Factor That Triggers Cell Cycle Re-entry In Differentiated Newt Myotubes
… established a cellular assay with a cultured newt myogenic cell line. Using this assay we have found a serum activity that stimulates cell cycle re-entry in differentiated multinucleated newt myotubes. The activity is present in serum of all mammalian species tested so far and, interestingly, …

Investigating the great crested newt landscape in a pond rich environment : developing a landscape scale management perspective
… of Triturus cristatus, the Great Crested Newt. The ecological foundations of wider landscape management concepts and knowledge base on T. cristatus' habitat requirements, dispersal and migration were explored. Species presence, and aquatic and terrestrial habitat on the Cholmondeley …

Sexual behaviour and sexual selection in newts
… on the sexual behaviour of the European smooth newt, Triturus vulgaris, and of the North American red-spotted newt, Notophthalmus Viridescens. Both belong to the family Salamandridae of the amphibian order Urodela. Chapter 1 introduces the concept of sexual selection, and those aspects of …

The effect of photoperiod on the gonads and basophilic adenohypophyseal cells of the rough-skinned newt, Taricha granulosa granulosa

Tetrodotoxin, fungal pathogen infection, and bacterial microbiome associations are variable in the skin microecosystems of two Taricha Newt species
… and microbiome composition in two Taricha newt species, Taricha granulosa and T. torosa, in the western USA. Among newt populations, there were significant differences in TTX concentration, but I found no evidence directly linking TTX concentration to Bd infection presence. In addition, I …

The effect of environmental and social factors on the courtship and mating dynamics of the smooth newt, Triturus v. vulgaris
… the courtship and mating dynamics of the smooth newt. Triturus v. vulgaris, was studied using laboratory experiments, an individual-based model, a semi-natural population and a field study. In view of the limitations of laboratory experiments and field observation, the semi-natural and modelling …

Diplostomulum trituri (Trematoda: diplostomatidae) a larval strigeoid trematode in the brain and cranial case of the newt, Notophthalmus viridescens (Rafinesque)
… the neural tissue by their oral sucker. In 150 newts examined from Mountain Lake, Giles County, Virginia, the incidence of infection with <u>D. trituri</u> was 100 percent. The total number of parasites in the brain and surrounding area ranged from 2 to 300. The number of mesocercariae in the …

The Role of Alarm Pheromones in Predation Avoidance By Adult Central Newts, Notophthalmus Viridescens
… system was tested in the field to determine if newts avoid areas marked with conspecific skin extract in a natural environment. Newts avoided traps marked with newt skin extract (NSE), but did not avoid traps marked with water or Plethodon skin extract (PSE). It is not known where the alarm …

Moral Majorities: The Rhetoric of “Real” American Values in Contemporary Conservatism
… they should act. I analyze books by Sarah Palin, Newt Gingrich, Glenn Beck, and Jenny Beth Martin to demonstrate how they premise "real" American identity on whether or not individuals are perceived to hold a particular set of moral values and beliefs. I ultimately suggest that their rhetorical …

Studying the Molecular Mechanisms for Generating Progenitor Cells during Tail Regeneration in Ambystoma mexicanum
… urodele regeneration. Urodele amphibians (newts and salamanders) are among the few vertebrates with the remarkable ability to regenerate lost body appendages, like the limbs and the tail. Urodele tail and limb regeneration occurs via blastemal epimorphic regeneration. A blastema is a mound …
