Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...
This book is based on a project to completely annotate what is known about the function of the ~150 genes encoded by the genome of the most commonly investigated baculovirus, AcMNPV. Once the annotation was completed (summarized in Chapter 11), the material was organized into a series of chapters integrating...
Identifying appropriate units for conservation requires knowledge of evolutionary
patterns and risks of managing at different geographical and genetic scales. I examined
genetic diversity at different geographical scales among 11,400 rainbow trout
(Oncorhynchus mykiss) from 243 locations in 13 major river basins throughout much of
their range and among coho...

The rapid pace of climate change is increasing tree mortality and highlighting the need to improve the mechanistic understanding of plant function under increased water stress. However, the processes that control soil moisture availability in steep mountainous terrain are poorly understood, as are the relative effects of atmospheric and soil...
A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology assumes that individuals within a species are functionally identical and that consumer-resource dynamics can be predicted solely by using species abundances. However, one species can consist of multiple functional groups,...
Nursery-grown seedlings are critical for attaining reforestation and restoration success in many ecosystems, including mixed-conifer forests in the Northwest, which is the native range for Douglas-fir (Pseudotsuga menziesii). Seedling establishment after planting depends on coordinated responses in seedling growth, physiology, and hydraulic function. The chapters in this dissertation review growth...
