Diatom-based reconstructions of earthquake-induced paleoenvironmental change in coastal Alaska and Washington, USA
… sensitive to earthquake-induced environmental change and are useful bioindicators in paloesiesmology studies. The two studies in this dissertation employ diatoms to create novel approaches to investigate behavior and recurrence of earthquakes along two subductions zones: Alaska-Aleutian …

Advances in the reconstruction of temperature history, physiology and paleoenvironmental change : evidence from light stable isotope chemistry
… are critical for testing environmental and/or paleoenvironmental hypotheses that seek to explain processes occurring over rapid or short time intervals. The investigation of climate variation (e.g., seasonality, El Niño, deglaciation), animal migration and physiology, and disturbance ecology …

Using a multiproxy analysis of springbok fossils to track 2 million years of vegetation changes experienced by hominins in southern Africa.
A causal link between climatic changes and hominin evolution is an established one, yet the exact dynamics of this relationship is debated. Key climatic changes, such as the intensification of the Northern Hemisphere Glaciation, the onset of the Walker Circulation and the Mid-Pleistocene …

Anatomy of a Carboniferous transgression: upper Tullig Cyclothem, County Clare, Ireland
… of, and controls upon, relative sea-level change, and 3) the paleoenvironmental transition from fluvio-deltaic to open marine conditions, and how this ties in to the overall evolution of the Western Irish Namurian Basin. These aims have been achieved by examination of all the outcrops of …

Two Post-Glacial Sagebrush Steppe Fire Records at the Wildland-Urban Interface, Eastern Cascades, Washington
Recent increases in large fires in the rapidly developing wildland-urban interface (WUI) areas of central Washington, where development intermixes with wildland fuels, contribute to federal firefighting costs exceeding of $1 billion annually. In addition, cheatgrass (<em>Bromus tectorum</em>) …
