The release of transgenes into the environment by transgenic plant species is a significant ecological concern, and consequently a containment method for these genetically modified organisms is highly sought after. For poplar trees, an option for containment is to produce trees that do not flower and therefore cannot spread genetic...

The release of transgenes into the environment by transgenic plant species is a significant ecological concern, and consequently a containment method for these genetically modified organisms is highly sought after. For poplar trees, an option for containment is to produce trees that do not flower and therefore cannot spread genetic...
Soil food webs process the majority of terrestrial carbon, and influence overall ecosystem function. A primary distinction among soil food webs is based on fungal versus bacterial pathways of decomposition; these lead to fundamentally different soil function, and are expected to differ in dominance between meadows and forests. This assumption...
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 fifth Oregon...
Cattle grazing and invasion by non-native plant species are globally-ubiquitous changes occurring to plant communities that are likely to reverberate through whole food webs. We used a manipulative field experiment to quantify how arthropod community structure differed in native and non-native California grassland communities in the presence and absence of...
This index provides access to infonnation about women in 102 books and journals. The information contained in each entry is only as good as the original and the quality varies considerably. Much of this infonnation has not before been easily accesible in this form. My hope is that this index...
Humans are increasing the scale and frequency of many natural disturbances, as well as adding novel disturbances to ecosystems. This thesis uses the arthropod community as a metric to examine the multi-trophic responses to disturbances in California grasslands. Chapter 2 explores how the long-term exclusion of native vertebrate herbivores has...
The present study characterized physiological responsivity during moral elevation, or elevation, a prosocial emotional state triggered by witnessing displays of altruism and moral beauty. Participants watched video stimuli that induced elevation, or amusement as a control condition, while heart rate (HR), respiratory sinus arrhythmia (RSA), skin conductance responses (SCR), and...
