Grazing Exclosure Experiment On The Henry Mountains Of Southern Utah, Johan Du Toit, Dustin Ranglack

Browse all Datasets

The data contained herein are the results of a grazing exclosure experiment on the Henry Mountains of S. Utah [38°5’ N, 100°50’W] to determine the relative impacts of bison, cattle, and lagomorphs on forage availability. Exclosures were erected in October 2011 and the standing crop of grass inside both exclosure types (full and partial), as well as an open reference plot was clipped in October 2012. Additionally, the local ranching community was surveyed to measure their perceptions of the bison – cattle conflict in the Henry Mountains.

Data From: Genotyping-By-Sequencing For Populus Population Genomics: An Assessment Of Genome Sampling Patterns And Filtering Approaches, Paul G. Wolf, Martin P. Schilling, Aaron M. Duffy, Hardeep S. Rai, Carol A. Rowe, Karen E. Mock, Bryce A. Richardson

Continuing advances in nucleotide sequencing technology are inspiring a suite of genomic approaches in studies of natural populations. Researchers are faced with data management and analytical scales that are increasing by orders of magnitude. With such dramatic advances comes a need to understand biases and error rates, which can be propagated and magnified in large-scale data acquisition and processing. Here we assess genomic sampling biases and the effects of various population-level data filtering strategies in a genotyping-by-sequencing (GBS) protocol. We focus on data from two species of Populus, because this genus has a relatively small genome and is emerging …

Sweeping Langmuir Probe (Slp) Of The Storms Sounding Rocket Mission, Padmashri Suresh, Charles Swenson

On October 30, 2007 NASA launched rocket 36.218 carrying the mission: “Investigation of Mid Latitude Ionospheric Irregularities Associated with Terrestrial Weather Systems” also known as the STORMS Mission. The rocket was launched from Wallops Island, Virginia (37.95◦ N, 284.53◦ E, 67.5◦ dip angle) at twelve minutes past local midnight. It flew along an azimuth of 114◦ and reached apogee near 394 km. The rocket payload had a suite of instruments from Utah State University/Space Dynamic Lab (USU/SDL) and University of Texas, Dallas (UTD), for making in-situ electron density, wind and electric field measurements.

The Sweeping Langmuir Probe or SLP was …

Data From: Further Examination Of The Geographic Range Of Eriogonum Corymbosum Var. Nilesii (Polygonaceae), Mark W. Ellis, Paul G. Wolf, Shannon Bardot, James A. Walton, Carol A. Rowe, Sarah Kulpa, Karen E. Mock

The buckwheat Eriogonum corymbosum is widely distributed throughout the southwestern United States, forming a complex of eight varieties. Eriogonum corymbosum var. nilesii is a primarily yellow-flowered taxon reported only from Clark County, Nevada. A previous genetic study by our research group found that variety nilesii is genetically distinct from other E. corymbosum varieties, based on a limited number of populations. Here, we assess genetic variation in 14 newly sampled yellow-flowered populations from southern Nevada, southern Utah, and northern Arizona, and compare them to genetic variation in six populations of previously determined E. corymbosum varieties. Of the new populations, we identified …

Metacom: Automated Data Processing And Analysis Of Metagenomic Community Sequences, Cody A. Tramp, Charles D. Miller

Browse all Datasets

Advances in next generation sequencing technology have allowed metagenomic researchers to study the composition of bacterial communities through analysis of the vast numbers of sequence reads that these technologies generate. It is not feasible to analyze and interpret this large amount of data manually and individual research groups must create automated scripts and programs to analyze this data. Here, we present MetaCom, a program that offers a common set of analysis and organizational tools that can be used by research groups in the analysis of environmental samples. MetaCom is an open-source software tool that can process next generation sequencing output, …
