Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister...
Rhizopogon is a hypogeous fungal genus that forms ectomycorrhizae
with genera of the Pinaceae. The greatest number and species of
Rhizopogon are found in coniferous forests of the Pacific Northwestern
United States, where members of the Pinaceae are also concentrated.
Rhizopogon spp. are host-specific primarily with Pinus spp. and
Pseudotsuga...
The La Ballena #3 site J69E is a shell midden located on Espiritu Santo Island in Baja California Sur. Archaeological excavations conducted in the summer of 2004 investigated a midden containing lithic and shell artifacts as well as faunal and human remains. Analysis of the debitage and formed lithic tool...
"The First North American Root Weevil Workshop was held at the Oregon State University North Willamette Research and Extension Center in Aurora, Oregon, November 1–2, 2001. The participants discussed topics including root weevil biology, detection, and monitoring, as well as the population dynamics and integrated pest management of root weevils...
Dynamic multithreaded processors attempt to increase the performance of a single
sequential program by dynamically extracting threads from sources such as loop
iterations. The scheduling of instructions in such a processor plays a vital role in the
amount of thread level parallelism that can be extracted and thus the overall...
In the fall through spring of 2002/03 and 2003/04, the composition of fish and amphibian communities were examined in intermittent streams in the upper Willamette river basin in western Oregon. I recorded standard aquatic habitat variables and water nutrient concentrations (nitrate and phosphate) and correlated them with fish and amphibian...
