Sparsely Ionizing Diagnostic And Natural Background Radiations Are Likely Preventing Cancer And Other Genomic-Instability-Associated Diseases, Bobby R Scott, Jennifer Di Palma Sep 2007

Sparsely Ionizing Diagnostic And Natural Background Radiations Are Likely Preventing Cancer And Other Genomic-Instability-Associated Diseases, Bobby R Scott, Jennifer Di Palma

Dose-Response: An International Journal

Routine diagnostic X-rays (e.g., chest X-rays, mammograms, computed tomography scans) and routine diagnostic nuclear medicine procedures using sparsely ionizing radiation forms (e.g., beta and gamma radiations) stimulate the removal of precancerous neoplastically transformed and other genomically unstable cells from the body (medical radiation hormesis). The indicated radiation hormesis arises because radiation doses above an individual-specific stochastic threshold activate a system of cooperative protective processes that include high-fidelity DNA repair/apoptosis (presumed p53 related), an auxiliary apoptosis process (PAM process) that is presumed p53-independent, and stimulated immunity. These forms of induced protection are called adapted protection because they are associated with the …


Hydrologic Alteration In The Connecticut River Basin, Kim Lutz, Julie Zimmerman, Ben Letcher, Keith Nislow Apr 2007

Hydrologic Alteration In The Connecticut River Basin, Kim Lutz, Julie Zimmerman, Ben Letcher, Keith Nislow

Water Resources Research Center Conferences

We examined the spatial distribution of hydrologic alteration among the Connecticut River and its 44 major tributaries as a tool for watershed-scale conservation planning and to assist in development of strategies for mitigating threats to aquatic ecosystems in the basin. Specifically, we (1) examined the spatial extent and distribution of hydrologic alteration by developing indices of potential flow alteration for individual watersheds, (2) analyzed data from US Geological Survey stream gages with sufficient periods of record (i.e., at least 20-years pre- and post- dam construction) to determine the types and degree of hydrologic alteration, and created unimpaired flow data sets …


Diversity And Movement Patterns Of Passerine Birds Near An Urban Center On Santa Cruz, Galapagos Islands, Ana M. Gabela Jan 2007

Diversity And Movement Patterns Of Passerine Birds Near An Urban Center On Santa Cruz, Galapagos Islands, Ana M. Gabela

Masters Theses 1911 - February 2014

Many insights into ecological and evolutionary processes have come from studies of island systems. Diversity, abundance, and movement of species are restricted on smaller islands, but these dynamics can become increasingly complex as island size increases.

In recent decades urbanization and the human population on the Galápagos islands has increased rapidly, affecting wildlife in unknown ways. During 2005 and 2006, we sampled birds along a 4-km transect extending northeast of the city of Puerto Ayora, Santa Cruz Island. This allowed us to collect data on the potential impacts of rapidly growing urban center on passerine bird diversity and abundance. We …
