In forest trees from temperate and boreal regions, cold acclimation is an important
adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...
Although assays have been done on the effects of vitamin E alpha-tocopherol (ɑ-tocopherol) on the lifespan of wildtype C. elegans, none have been done on the effects of the vitamin on mutant strains with mitochondrial mutations. By using a mev-1 genetic mutant strain of C. elegans with higher levels of...
As the world’s population continues to increase every year, a greater proportion of people are living in urban environments. This process of global urbanization has been previously shown to affect evolution of plants and animals by restricting gene flow, increasing genetic drift, and causing divergent selection between rural and urban...
Identifying habitat and spatial requirements of wildlife species across multiple spatial scales is a challenging, yet crucial component of wildlife management. Habitat use of bats is particularly difficult to study, and managing habitat to conserve bats is especially challenging because bats are highly vagile organisms that exploit several different types...

Identifying habitat and spatial requirements of wildlife species across
Wood stiffness is one of the most important properties of lumber and veneer. We studied wood stiffness (modulus of elasticity, MOE), wood density, microfibril angle, and knots in a 25 year-old wind pollinated progeny test (50 families, ~ 373 trees) of coastal Douglas-fir to understand the potential for genetically improving...
Wildlife managers often use species distribution models (SDMs) as an initial tool in conservation planning. Managers and researchers have made efforts to model the habitat and distribution of pygmy rabbits (Brachylagus idahoensis) across their historic range since the species was proposed for listing under the Endangered Species Act (USFWS 2003)....
Riparian zones are ecotones between terrestrial and aquatic ecosystems. Processes in streams are strongly influenced by riparian forest communities, age, stage and structure. Temperate forests across much of North America, including riparian areas, are recovering from historic land clearing with many stands in the stem-exclusion phase of development in which...
The purpose of this dissertation was to estimate the extent to which group-level synchrony predicts specific group outcomes. Synchrony is broadly defined as the coordination of biological and behavioral processes during social contact (Feldman, 2017). In this dissertation, biological coordination is defined as, “the spontaneous synchronization of physiological signals (e.g.,...
The purpose of this thesis was to assess the relationship between group rapport and nonverbal expressivity using three data sources: self-report, observer ratings, and test data. Assessing these constructs using multiple data sources enabled the construction of multitrait-multimethod matrices. These matrices allowed for a critical evaluation of the convergent and...
