Supplemental data to \"Estimating the Genetic Diversity of Pacific salmon and trout using Multi-gene eDNA Metabarcoding\"

Kevin Weitemier, Brooke E. Penaluna, Laura Hauck, Lucas J. Longway, Tiffany Garcia & Richard Cronn
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 codon position, and calculation of diversity statistics and haplotype mapping. Intermediate outputs include denoised haplotypes, entropy calculations, and haplotype summaries following chimera removal.

Zooplankton in Upper Willamette Reservoirs, 2015

Christina Murphy, Amanda Pollock, Angela Strecker & Sherri Johnson
Samples targeting crustacean zooplankton were collected from 3 upper Willamette Basin reservoirs during May-August 2015. Van Dorn sampling devices were used to collect samples at discrete depths from Fall Creek Reservoir, Lookout Point Reservoir, and Hills Creek Reservoir. Zooplankton samples were collected during daytime and nighttime corresponding with the new moon phase to evaluate zooplankton diel migration in these reservoirs. Zooplankton were visually identified using a microscope and the quantity found at each depth was...

Hyperspectral imagery of Pinus strobiformis infected with fungal pathogen

Marja Haagsma, Gerald F. M. Page & Jeremy S. Johnson
Hyperspectral images were taken from March till October, 2018, of southwestern white pine (Pinus strobiformis), SWWP, seedlings of ten different seed-source families. Half of the seedlings were inoculated with white pine blister rust (Cronartium ribicola). Visual assessments of vigor coincided with hyperspectral data acquisition. The aim of the experiment was to use hyperspectral data to automaticaly and objectively identify infection and degree of infection in SWWP seedlings. Moreover, we developed and evaluated a feature importance...

Fall Creek Reservoir Water Quality Dataset

Stephen Hamilton, Christina Murphy, Sherri Johnson & Amanda Pollock
Water chemistry measurements taken at or downstream of Fall Creek Reservoir, OR (43.9459714, -122.755765). Fall Creek is a tributary of the Middle Fork Willamette River, located approximately 20 miles SE of Eugene, Oregon, USA. Water chemistry measurements included water samples collected from the reservoir outflow (during autumn drawdown) and within Fall Creek Reservoir (during August). These water samples were analyzed to determine concentrations of dissolved organic carbon, suspended sediment, and nutrients. A sonde was used...

Phytoplankton in Upper Willamette Reservoirs Dataset

Christina Murphy, Amanda Pollock, Ivan Arismendi & Sherri Johnson
Phytoplankton samples were collected from 5 upper Willamette Basin reservoirs in variable months during years 2013-2016 and 2019. Samples were collected from Blue River Reservoir, Cougar Reservoir, Fall Creek Reservoir, Lookout Point Reservoir, and Hills Creek Reservoir. The phytoplankton were identified and enumerated by Jim Sweet at Aquatic Analysts. Density and biovolume were calculated for each phytoplankton species identified per sample collected. This dataset also includes environmental parameters corresponding to sample collection date or the...
