Capabilities and limitations of using DNA metabarcoding to study plant-pollinator interactions

Katherine Arstingstall, Sandra DeBano, Xiaoping Li, David Wooster, Mary Rowland, Skyler Burrows & Kenneth Frost
Many pollinator populations are experiencing declines, emphasizing the need for a better understanding of the complex relationship between bees and flowering plants. Using DNA metabarcoding to describe plant-pollinator interactions eliminates many challenges associated with traditional methods and has the potential to reveal a more comprehensive understanding of foraging behavior and pollinator life history. Here we use DNA metabarcoding of ITS2 and rbcL gene regions to identify plant species present in pollen loads of 404 bees...

Do fine-scale experiments underestimate predator consumption rates?

Lindsey Bruckerhoff, Casey Pennock & Keith Gido
Understanding ecological processes across spatial scales helps link observations and predictions from experiments to ecological patterns occurring at coarser scales relevant to management and conservation. Using fish, we experimentally manipulated the size of arenas to test the spatial scaling of predator-prey interactions. We measured variation in predator consumption and prey behavior (prey aggregation, spatial overlap with predators, and movement) across arena sizes. Variation in prey behavior across arena sizes was hypothesized to drive consumption patterns...

Data from: Fractal triads efficiently sample ecological diversity and processes across spatial scales

Elizabeth Simpson & William Pearse
The relative influence of ecological assembly processes, such as environmental filtering, competition, and dispersal, vary across spatial scales. Changes in phylogenetic and taxonomic diversity across environments provide insight into these processes, however, it is challenging to assess the effect of spatial scale on these metrics. Here, we outline a nested sampling design that fractally spaces sampling locations to concentrate statistical power across spatial scales in a study area. We test this design in northeast Utah,...

Revision of the genus Jethsura Cameron, 1902 (Hymenoptera: Ichneumonidae: Ichneumoninae: Phaeogenini)

Brandon Claridge
The genus Jethsura Cameron is revised. Jethsura euthenia sp. nov., Jethsura gondawindua sp. nov., and Jethsura serpentina sp. nov. are newly described from Colombia, and Jethsura rubricauda sp. nov. is described from Mexico. Jethsura pyriformis (Provancher) from the Nearctic region is redescribed. Species images, distribution maps and an illustrated key is provided.

The 2020 National Snow Load Study

Brennan Bean, Marc Maguire, Yan Sun, Jadon Wagstaff, Salam Adil Al-Rubaye, Jesse Wheeler, Scout Jarman & Miranda Rogers
The United States has a rich history of snow load studies at the state and national level. The current ASCE 7 snow loads are based on studies performed at the Cold Regions Research and Engineering Laboratory (CRREL) ca. 1980 and updated ca. 1993. The map includes large regions where a site-specific case study is required to establish the load. Many state reports attempt to address the "case-study regions" designated in the current ASCE 7 design...

Digital Appendix of Masters Thesis \"Constraining deformation mechanisms of damage zones: A case study of the shallow San Andreas Fault at Elizabeth Lake, Southern California\"

James Evans & Caroline Studnicky
We performed macroscopic, optical petrographic, scanning electron microscopy, and geochemical analyses on rock core acquired across the San Andreas Fault at Elizabeth Lake, California, in order to understand the distribution and accommodation of fault-related slip and energy within the shallow damage zone of this continental scale strike-slip fault. We characterized the deformation structures, alteration textures, and elemental variabilities to constrain the properties of the uppermost ~2 km fault-related damage zone at this site. We identified...

Standard Non-Uniform Noise Dataset

Andres Imperial & John Edwards
Fixed Pattern Noise Non-Uniformity Correction through K-Means Clustering Fixed pattern noise removal from imagery by software correction is a practical approach compared to a physical hardware correction because it allows for correction post-capture of the imagery. Fixed pattern noise presents a unique challenge for de-noising techniques as the noise does not present itself where large number statistics are effective. Traditional noise removal techniques such as blurring or despeckling produce poor correction results because of a...

Data for Farmland Preservation Study

Arthur J. Caplan & Brent C. Chamberlain
This study fills a gap in cultural ecosystem service (CES) assessment of prime farmland located in peri-urban areas by presenting results from a choice experiment recently conducted in Utah’s Wasatch Front region. The choice experiment was designed to account for heterogeneous effects associated with a wide array of socio-demographic and attitudinal characteristics on household preferences for farmland preservation, including farmland used for the joint production of solar power and agricultural products. We apply a mixed-logit...

Data from: Yellow Air Day Advisory Study

Arthur J. Caplan
Using a dataset consisting of daily vehicle trips, PM2.5 concentrations, along with a host of climactic control variables, we test the hypothesis that “yellow air day” advisories provided by the Utah Division of Air Quality resulted in subsequent reductions in vehicle trips taken during northern Utah’s winter-inversion seasons in the early 2000s. Winter inversions occur in northern Utah when climactic conditions are such that PM2.5 concentrations (derived mainly from vehicle emissions) become trapped in the...
