Following high-severity fire, forest succession may take alternate pathways depending on the pattern of the fire and any secondary disturbances during early stand development, with lasting consequences for ecosystem function. The objectives of this research were to quantify: (1) early postfire regeneration as influenced by the spatial pattern of a...
Both the structure and composition of naturally generated early-seral forests in the Pacific Northwest (PNW) can be profoundly different than that of more developed forest seres, especially in the period after a major disturbance but before conifers re-develop a closed canopy. While it is reasonable to suggest that the unique...
A key uncertainty concerning the effect of wildfire on carbon dynamics is the rate at which fire-killed biomass (e.g., dead trees) decays and emits carbon to the atmosphere. We used a ground-based approach to compute decomposition of forest biomass killed, but not combusted, in the Biscuit Fire of 2002, an...
Dynamics of dead wood, a key component of forest structure, are not well described for mixed-severity fire regimes with widely varying fire intervals. A prominent form of such variation is when two stand-replacing fires occur in rapid succession, commonly termed an early-seral “reburn.” These events are thought to strongly influence...
Final report for project completed with funding from the Oregon State University Agricultural Research Foundation Continuing Researchers Support Program.
This study quantifies the short-term effects of low-, moderate-, and high-severity fire on carbon pools and fluxes in the Eastern Cascades of Oregon. We surveyed 64 forest stands across four fires that burned 41,000 ha (35%) of the Metolius Watershed in 2002 and 2003, stratifying the landscape by burn severity...
Mangroves provide a wide range of ecosystem services, including nutrient cycling, soil formation, wood production, fish spawning grounds, ecotourism and carbon (C) storage¹. High rates of tree and plant growth, coupled with anaerobic, water-logged soils that slow decomposition, result in large long-term C storage. Given their global significance as large...
Celebrity culture is part of a long history of fame, but the modern celebrity individual came into focus in the nineteenth century. The first part of this thesis distinguishes modern celebrity – including its morality – from other types of fame, explores the intersection of celebrity and gender through the...
Chlamydia possesses an immense importance within both human and animal medicine when looking at pathogens. Chlamydia trachomatis infections have been shown to affect both the eye and genital tracts in millions of humans and animals every year [13]. As C. trachomatis strains are highly conserved in patients, it has made...
The ferritin-like superfamily (FLSF) of proteins is composed of a wide variety of functionally diverse proteins involved in oxygen dependent metal-mediated electron transfer reactions. Their biological importance is exemplified by the fact FLSF proteins are found in almost every organism from all three domains of life. Their functions range from...
