Cyanobacterial blooms are a growing concern in the Pacific Northwest because of their
threat to watershed health and drinking water supplies. Bacteriophages are pathogens of
bacteria and may contribute to the growth and decline of seasonal blooms. Bacteriophage
S-CRM01, a lytic T4-type myophage, has been isolated from a freshwater strain...

An interactive map of important watersheds in the United States was created for use as a teaching tool in an estuarine ecology class. Figures and explanations of important factors influencing river ecology were created using data downloaded from the U.S. Geologic Survey. This interface serves as a visualization of biological,...
Ceratonova shasta is a myxozoan parasite that affects populations of salmonid species in the Pacific Northwest and is the cause of enteronecrosis. It has a complex life cycle involving two hosts; a definitive annelid host, Manayunkia speciosa (polychaete), and an intermediate salmonid host. Klamath River M. speciosa are genetically variable...
Myxobolus squamalis is a Myxozoan parasite of salmonids, which contributes to lowered fitness of hatchery and wild fish in the Pacific Northwest of North America. The only GenBank DNA sequence of M. squamalis is from Oncorhynchus tschawytscha (Chinook), but is not linked to a published morphological description. There is a...
Coral reef health has been in severe decline around the globe in the past several
decades, in many cases due to direct human impact. Human action, such as overfishing,
habitat destruction and nutrient loading, has caused coral coverage to drop to record lows,
threatening the future of these critically important...
Transects were run at five locations in the Benton County area searching for
samples of Chlorociboria spp. on dead wood, with fifteen total samples found. Of
these samples, eight samples had the wood species identified, with the majority found
on Acer macrophyllum and one on Salix spp. The density of...
Barley yellow dwarf (BYD) is a damaging luteovirus disease responsible for reduced tillering, delayed heading, sterility, and stunting in many cereals worldwide. Well-characterized resistance genes to barley yellow dwarf viruses (BYDV) are scarce and genes conferring tolerance to BYDV are limited in wheat. In an attempt to generate plants with...
Erwinia amylovora is a plant pathogenic bacterium that causes the destructive disease fire blight of apple and pear. We examined the plasmid content of a collection of 305 isolates of E. amylovora from Washington and Oregon with PCR assays and RFLP. Nearly all isolates of E. amylovora carried plasmid pEA29,...
Using X-ray computed tomography (CT) scanning to characterize the physical characteristics of soil and sediment cores allows scientists to observe and analyze stratigraphy without destroying the integrity of different layers. Microbiologists often work with geologists to characterize the microbial communities in such cores; however, X-rays are known to be destructive...
