Abstract:: In today’s world, memes have become a second language. They are used to explain emotions, make fun of our friends, convey inside jokes, comment on the world around us, and so much more. They are a quick way to show a friend how you are feeling or to start a...

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

Creator:: Kreul, Taylor G.
Abstract:: As the zebrafish (Danio rerio) becomes increasingly popular as a biomedical model for various laboratory studies, the need for efficient and accurate diagnostic assays for the pathogens that infect it has grown. The most common pathogen infecting laboratory zebrafish is Pseudoloma neurophilia, a microsporidium that has been known to cause...

Abstract:: The bluffs and plateaus of the eastern Columbia River are floristically rich and ecologically intricate. A previous descriptive study of the unique scabland vegetation on the Gov. Tom McCall Preserve at Rowena Plateau in Oregon included delineation of several distinct or intergrading native and non-native vegetation units. In this study...

Creator:: Valente, Jonathon J. and Betts, Matthew G.
Abstract:: Aim The hypothesis that habitat fragmentation negatively influences biodiversity stems from island biogeography and metapopulation theory which predict negative impacts of decreasing patch size on richness and distribution patterns. Empirical support of this idea is weak in terrestrial systems, though tests of fragmentation effects are typically confounded with landscape composition...

Abstract:: Ecological impacts of climate change in the Pacific Northwest may hinge on acclimation to drier summers, highlighting the importance of plant physiological studies in forests. Evaluating dominant forest plant species under old-growth and managed forest conditions is similarly important as timber harvest might change microclimates and alter drought effects on...

Abstract:: The brine shrimp (Artemia salina) bioassay was used to screen 211 methanol extracts from 128 species of Pacific Northwest plants in search of general cytotoxic activity. Strong toxicity (LC₅₀ < 100 µg/ml) was found for 17 extracts from 13 species, with highest activity observed for Angelica arguta roots at <10...
