Management in fire-prone ecosystems relies widely upon application of prescribed fire and/or fire surrogate (e.g., forest thinning) treatments to maintain biodiversity and ecosystem function. Recently, published literature examining wildlife response to fire and fire management has increased rapidly. However, none of this literature has been synthesized quantitatively, precluding assessment of...
The objective of this dissertation was to understand the physical mechanisms affecting inversion events in a complex forested mountain landscape. This work was motivated by the long-term studies of climate at the Andrews Forest, short-term studies of vertical temperature, light, wind, and moisture gradient in old-growth trees, and interest in...
Most philosophical discussions of moral consideration for animals focus on
animals as a single category, neglecting to differentiate them by type or role (such as
wild, domestic, laboratory, or companion). Moreover, the importance of the individual
animal in terms of relationship to humans is de-emphasised.
Animals should not be discussed...
Research relying on remotely sensed data on land use and deforestation has exploded in recent years. While satellite-based measures have clear advantages in terms of coverage, the presence of measurement error within these products is often overlooked. Here, we detail the econometric implications of these errors when analyzing the determinants...
Collective migration in animal groups is often guided by distributed leader agents that influence their peers by modulating their motion behaviors. Distributed leadership is a promising navigation strategy for artificial swarms, but designing the leaders’ controllers is difficult due to the swarm’s collective emergent behaviors. The presented research formulates a...
This report describes the observations and opinions of Douglas County homeless youth and of the social service providers and advocates focused on assisting them. Initiated by the county’s Commission on Children and Families, and conducted by Oregon State University researchers, this study provides data and analysis which may assist service...
In their respective novels, The House Behind the Cedars (1900) and
Passing (1929), both Charles Chesnutt and Nella Larsen utilize racial
passing, the process of a mixed-race individual living as "white," to
explore the relations between black and white people during early-twentieth century America. This thesis specifically argues that
Chesnutt...
Seasonal diet and food selection of California quail (Callipepla
californica) were studied at E.E. Wilson Wildlife Area, Oregon,
during 1985 to 1987. Analysis of diets of 105 quail, along with
information from 117 quail taken during 1976 to 1978 revealed 14 key
plant foods. Collectively, the key foods composed 87%...
