Understanding the drivers and implications of anthropogenic disturbance of ecological connectivity is a key concern for the conservation of biodiversity and 50 ecosystem processes. Here, we review human activities that affect the movements and dispersal of aquatic organisms, including damming of rivers, river regulation, habitat loss and alteration, human-assisted dispersal...

Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms
are often invoked to explain their origin. However, genetic recombination can constrain the ability of divergent selection to produce
reproductive isolation in sympatry. Recombination breaks up favorable combinations of traits (”adaptive suites”) if individual
traits are...
The morphology and genesis of soils of the Willamette series
and of some Willamette-associated soils and their relationships to
geomorphic surfaces were studied in an area near McCoy, Polk
County, Oregon. Influences of regional extent, such as climate and
parent material, were related to the soils and landforms. The soils...
A model of acute glutamate- and domoate-induced toxicity was developed and characterized in cultured rat cerebellar granule cells (CGCs) using experimental conditions which preserve the voltage-dependency of NMDA receptor function. Glutamate, which is normally non-toxic to CGCs in physiologic media (pH 7.4), was shown to induce a cytotoxic response after...
This study investigated associations among teachers' pedagogical content beliefs,
approaches to teaching, and their students' achievement in a high school Advanced
Placement (AP) Calculus setting. The three major research questions concerned: (a)
how well Al' calculus teachers' pedagogical beliefs about mathematics, curriculum, and
instruction aligned with a constuctivist point of...
This is a report of a survey-based, primary data inter-industrial trade model of the Malheur County economy. Such model, popularly known as county input-output models, are used to project impacts and monetary trade-offs associated with changes in external markets, local technologies, and input availabilities.
