Geographic Variability in Elevation and Topographic Constraints on the Distribution of Native and Nonnative Trout in the Great Basin

Creator:: Warren, Dana R., Dunham, Jason B., and Hockman-Wert, David
Abstract:: Understanding local and geographic factors influencing species distributions is a prerequisite for conservation planning. Our objective in this study was to model local and geographic variability in elevations occupied by native and nonnative trout in the northwestern Great Basin, USA. To this end, we analyzed a large existing data set...

ArismendiIvanFisheriesWildlifeDifferentialInvasionSuccess.pdf

Creator:: Arismendi, Ivan, Penaluna, Brooke E., Dunham, Jason B., and et al.
Abstract:: Biological invasions create complex ecological and societal issues worldwide. Most of the knowledge about invasions comes only from successful invaders, but less is known about which processes determine the differential success of invasions. In this review, we develop a framework to identify the main dimensions driving the success and failure...

Descriptors of natural thermal regimes in streams and their responsiveness to change in the Pacific Northwest of North America

Creator:: Arismendi, Ivan, Johnson, Sherri L., Dunham, Jason B., and Haggerty, Roy
Abstract:: 1. Temperature is a major driver of ecological processes in stream ecosystems, yet the dynamics of thermal regimes remain poorly described. Most work has focused on relatively simple descriptors that fail to capture the full range of conditions that characterise thermal regimes of streams across seasons or throughout the year....

Instream cover and shade mediate avian predation on trout in semi-natural streams

Creator:: Penaluna, Brooke E., Dunham, Jason B., and Noakes, David L. G.
Abstract:: Piscivory by birds can be significant, particularly on fish in small streams and during seasonal low flow when available cover from predators can be limited. Yet, how varying amounts of cover may change the extent of predation mortality from avian predators on fish is not clear. We evaluated size-selective survival...

Consistency of associate degree definitions and graduation requirements in the California community colleges : perceptions of community college curricular leaders

Creator:: Borg, Carolyn Sue
Abstract:: The purpose of this study was to produce data and information that inform California Community College decision-makers of: (a) extent of variance in California's associate degree definitions and graduation requirements, and (b) perceptions of curricular leaders regarding the variances. Associate degree definitions and graduation requirements were compiled and analyzed from...

An investigation into the characteristics, perceptions, and expectations of high school students involved in a pilot statewide tech prep in agriculture program in Washington state

Creator:: Willis, James Franklin
Abstract:: The purpose of the investigation was to develop a profile of characteristics, perceptions and expectations of high school students involved in the Washington Tech Prep in Agriculture Statewide Articulation Program (TPAG). The investigation involved nine individual interviews, the responses of 165 students to a forced response survey instrument, and a...

The paradox of cooling streams in a warming world:Regional climate trends do not parallel variable local trends in stream temperature in the Pacific continental United States

Creator:: Arismendi, Ivan, Johnson, Sherri L., Dunham, Jason B., Haggerty, Roy, and Hockman-Wert, David
Abstract:: Temperature is a fundamentally important driver of ecosystem processes in streams. Recent warming of terrestrial climates around the globe has motivated concern about consequent increases in stream temperature. More specifically, observed trends of increasing air temperature and declining stream flow are widely believed to result in corresponding increases in stream...
