Phylogenetics, Biogeography, And Climate Niche Variation Of South Pacific And Hawaiian Psychotria, Elaine Zhang

Master's Theses

Why do some species have broad geographic distributions, while other species are confined to a narrow distribution? Species age, ecological niche, or dispersal traits may help explain why some insular species are abundant and found on many islands, while others are rare and restricted to one island. In this study, I inferred a robust, time-calibrated phylogeny of the Hawaiian Psychotria, using two nuclear and eight chloroplast loci, sampling 67 individuals. I coupled my phylogenetic hypothesis with climatic data, ecological niche modeling, and morphological dispersal characteristics to explain the variation in number of islands occupied by each species. My inferred phylogeny …

Compounding Fire Disturbance History Encourages Coast Redwood (Sequoia Sempervirens) Regeneration And Community Dominance, Matthew R. Brousil

Master's Theses

Disturbance is fundamental to forest ecosystem function and overall health, but climate change is likely to increase both disturbance frequency and intensity in the future. Forests subject to increasingly frequent and intense disturbances are more likely to experience compounding disturbance effects. Compounding disturbances may exert unpredicted, non-additive stresses on ecosystems, leading to novel conditions that may exceed the capacity for local species to survive and regenerate. I further hypothesize that compounding disturbances could create conditions misaligned with species’ adaptations by altering physical and chemical growing conditions in forest soils, affecting forest composition, structure, and, subsequently, function for many years following …

Trail Vision: Utilizing Leopold As Environmental Equipment For Living, Kendall Elizabeth Barrett

Master's Theses

Hiking trails are one of the major ways citizens make observations about the natural world. An analysis of trail maintenance texts demonstrates a focus on concealment and camouflage of human construction and upkeep in National Scenic Trails. These practices are detrimental to environmentalism, since the resulting ideology frames nature as overly self-sufficient and not in need of human stewardship. Trail maintenance practices are analyzed in reference to the nature/culture dichotomy. Perceptions of nature’s self-healing ability are analyzed through a comparison of the oil spills in Santa Barbara during 1969 and 2015. An alternative approach is found through Aldo Leopold. Leopold …
