In July 2005, Bonnie Parks spoke with Terry Reese, digital production unit head at Oregon State University’s Valley Library. In this interview, Reese shares his views on topics ranging from electronic journal management, the role of the catalog, to the impact Google scholar might have on the way libraries provide...
A classification of forest vegetation is presented for the Colville National Forest in northeastern
Washington State. It is based on potential vegetation with the plant association as the basic unit. The
classification is based on a sample of approximately 229 intensive plots and 282 reconnaisance plots
distributed across the forest...
The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...
The purposes of this study were to (a) provide insight into the use of item response theory (IRT) with psychomotor skills, (b) assess the psychometric properties of the Test of Gross Motor Development (TGMD) using IRT, and (c) provide a basis for future studies of the TGMD using IRT. The...
Competitive exclusion is a key concept in ecology describing the exclusion of one species by another from access to a limited resource. Competitive interactions between chipmunk species in the Great Basin, documented by James Brown in 1970, are often used as a textbook example of competitive exclusion. Whether competitive interactions...
Ecology is focused on understanding how organisms interact with each other and their environments, across ecological, spatial, and temporal scales. Thus, understanding how processes and patterns of ecological systems change across space and time is a principle goal for conservation biologist globally. While many approaches exist for investigating the changing...
Anthropogenic climate change is threatening biodiversity as I currently understand it. There is now a large body of work highlighting species responses, globally, to this threat. Importantly, responses at the species level emerge from responses at lower levels of biological organization (individuals and populations) across a species’ geographic range. For...
Building upon Deci and Ryan's (1985, 1991) self-determination theory as well as
previous empirical work on motivation, the present study was designed to develop a
multifaceted 31-item Exercise Motivation Scale (EMS). A series of pilot studies were
first conducted in order to generate the 31 scale items. The EMS was...
The purpose of this study was to examine pressure at
five selected sites on the plantar surface of the foot and
adaptations in running kinematics among fourteen male
varsity collegiate distance runners on five different
surfaces--asphalt, cinders, concrete, grass, and tartan.
Pressure data were collected with an Electrodynogram system
(EDG)...
