In this study, I investigate how target value uncertainty may lead to acquirer mispricing of an acquisition target and how the mispricing may be a determinant of goodwill impairment. To the extent the mispricing leads to both high and low industry-adjusted purchase price multiples (PPMs are my proxies for overpayment...
The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data of hybrids occurrences makes assessing hybridization risk difficult. Here, I developed a spatially-explicit GIS Hybridization Risk Model (HRM) between native ESA-listed Bull Trout and introduced Brook Trout by...
In recent years, monarch butterfly (Danaus plexippus) populations have declined at an alarming rate resulting in an extensive conservation effort across the species’ migratory range. One hypothesis for declining populations is decreased reproductive success during spring migration. The eastern monarch population’s first annual generation occurs in the early spring when...
The biotransformation of hop aroma via yeast is a prominent topic in the brewing industry with considerable interest placed on how yeast can enhance volatile thiol production during wort fermentation. Three potent thiols are known contributors to tropical qualities in wine and beer aroma, specifically 3-mercaptohexan-1-ol (3MH), 3-mercaptohexyl acetate (3MHA),...
Hop (Humulus lupulus L. var. lupulus) is a diploid, dioecious plant with an extensive history of cultivation and use in brewing, as a textile, and for its therapeutic properties. Hop is prized for its ability to produce a variety of aromatic and flavor compounds, as well as compounds with anti-microbial...
Connectivity of fish populations is a crucial question for fisheries conservation and the development of spatial management plans. Both adult and larval movement define the extent and direction of ecological and evolutionary overlap between geographic regions and, therefore, how we define stocks for management purposes. Within that context, my work...
The word orogenesis is derived from the Greek words oros meaning mountains and genesis meaning creation and refers to the study of the complex processes involved in the growth and evolution of mountain ranges (orogens). Orogens develop where crustal deformation builds topography and forms landscapes. This dissertation explores the role...
Daily cyclical changes of light are brought on by the axial rotation of the Earth while seasonal changes in light are caused by Earth’s tilt as it revolves around the sun. Major life history traits, such as development, which are tied to metabolic processes, have a strong link to the...
The global cryosphere, defined as the world’s ice and snow covered regions, is a crucial water source for society and ecosystem functions, as well as an important regulator of the earth’s energy budget. Melt from glaciers and seasonal snow cover provides water for more than a sixth of the world’s...
Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This sixth Oregon...
