The legality of wood products in trade often depends on their geographic origin, creating a need for forensic tools that can verify claims of provenance for wood and wood products. Cedrela odorata L. or Spanish cedar is a target of illegal logging. We developed a 140 SNP Agena™ MassARRAY® assay...
This dataset contains records of identified benthic and aquatic emergent invertebrates from pre-timber harvest, post-timber harvest, and reference (no harvest) collection sites in the Hinkle Creek watershed. A variety of fish-bearing tributaries, fishless tributaries, and mainstem creek sites were sampled. Benthic invertebrates were collected using Serber nets and emergent adults...
European green crab, Carcinus maenas, trapped and collected in coastal Oregon and Washington coastal estuaries during the 2019. Data for individual crabs include: estuary, site, date of collection, sex, carapace width, weight, molt stage (color of abdomen), missing limbs, estimated year class, method of collection, and name of collector.

To detect and avoid illegal logging of valuable tree species, identification methods for the origin of timber are necessary. We used next-generation sequencing to identify chloroplast genome regions that differentiate the origin of white oaks from the three continents; Asia, Europe, and North America. By using the chloroplast genome of...
This dataset contains DNA sequence data of Oncorhynchus species, isolated from environmental DNA (eDNA) from Pacific Northwest streams via microfluidic eDNA metabarcoding and high-throughput (Ilummina) sequencing (samples collected from 2017-09-22 to 2017-10-10). It is accompanied by scripts and commands for data analyses including: sequence denoising, calculation of entropy values by...
This dataset contains the taxonomic classifications of environmental DNA (eDNA) sequences obtained from Fall Creek, Oregon, via microfluidic multiplex PCR (Fluidigm Access Array) and high-throughput sequencing. It is accompanied by electrofishing counts taken at the same time as the eDNA samples. Metadata and R scripts are provided to analyze the...
The trophic habits, size and condition of yearling Chinook salmon (Oncorhynchus tshawytscha) caught early in their marine residence were examined during 19 survey years (1981–1985; 1998–2011). Juvenile salmon consumed distinct highly piscivorous diets in cold and warm ocean regimes with major differences between ocean regimes driven by changes in consumption...
Field surveys were conducted by collecting soil samples to estimate
nematode densities in soil from winter wheat, spring wheat, spring
barley, and spring legumes (lentil, chickpea, and pea) fields during
2010 and 2011. Pratylenchus spp. were observed in 60% of sampled
fields. However, nematodes were detected in nearly all of...
Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
