Data From: Characterizing patterns of genomic variation in the threatened Utah prairie dog: implications for conservation and management
<p>Utah prairie dogs (<i>Cynomys parvidens</i>) are federally threatened due to eradication campaigns, habitat destruction, and outbreaks of plague. Today, Utah prairie dogs exist in small, isolated populations, making them less demographically stable and more susceptible to erosion of genetic variation by genetic drift. We characterized patterns of genetic structure at neutral and putatively adaptive loci in order to evaluate the relative effects of genetic drift and local adaptation on population divergence. We sampled individuals across the Utah prairie dog species range and generated 2,955 single nucleotide polymorphisms (SNPs) using double digest restriction site associated DNA sequencing (ddRAD). Genetic diversity was lower in low elevation sites compared to high elevation sites. Population divergence was high among sites and followed an isolation-by-distance (IBD) model. Our results indicate that genetic drift plays a substantial role in the population divergence of the Utah prairie dog, and colonies would likely benefit from translocation of individuals between recovery units, which are characterized by distinct elevations, despite the detection of environmental associations with outlier loci. By understanding the processes that shape genetic structure, better informed decisions can be made with respect to the management of threatened species to ensure that adaptation is not stymied.</p>
Data from: Hurdiid radiodontans from the middle Cambrian (Series 3) of Utah
Radiodontan body elements, some belonging to Peytoia and Hurdia and some unassigned, have been reported from the Langston Formation (Spence Shale Member), Wheeler Formation, and Marjum Formation of the middle Cambrian (Series 3) of Utah. These identifications are reassessed in light of recent work on the morphology of the radiodontan Hurdia. New specimens of Hurdia are identified from the Spence Shale, representing mouthparts (oral cones), cephalic carapace H-elements, frontal appendages, and a single isolated swimming flap. The shape of the H-elements allows H. victoria Walcott, 1912 to be identified from the Spence Shale for the first time. The flap is larger and more complete than any reported from the Burgess Shale and allows for a better understanding of the morphology of Hurdia swimming flaps. A 3D model of a Hurdia frontal appendage indicates that there is only one morph of Hurdia frontal appendage found in both species, and apparent morphological differences between disarticulated appendages reflect a preservational continuum caused by varying oblique angles relative to the seafloor. Peytoia should no longer be reported from the Spence Shale, but its presence is confirmed in the Wheeler and Marjum formations. New mouthparts (oral cones) of Hurdia from the Spence Shale and Peytoia from the Marjum Formation with surface textures of submillimeter-diameter raised nodes are described. These new features have not been observed in material from the Burgess Shale and suggest slight differences in preservation.
Data from: The 'Last Hurrah of the Reigning Darwinulocopines'? Ostracoda (Arthropoda, Crustacea) from the Lower Jurassic Moenave Formation, Arizona and Utah, USA
An ostracod fauna is described from lacustrine sediments of the Hettangian, Lower Jurassic Whitmore Point Member of the Moenave Formation. The Moenave is well known for its rich, Late Triassic?–Early Jurassic fossil record, which includes fossil fishes, stromatolites, ostracods, spinicaudatans and a diverse ichnofauna of invertebrates and vertebrates. Four ostracod species, all belonging to the suborder Darwinulocopina, were recovered from these sediments: Suchonellina globosa, Suchonellina stricta, Whipplella? sp. 1 and Whipplella? sp. 2. The diversity and composition of the Whitmore Point Member ostracod fauna agree with previous interpretations about Lake Dixie and nearby paleoenvironments as shallow lakes, where darwinulocopine species which survived the effects of the Central Atlantic Magmatic Province and the subsequent End-Triassic extinction quickly recolonized these areas thanks to asexual reproduction by parthenogenesis. The Lake Dixie region, in its geographical isolation, may represent the last episode of darwinulocopine dominance in non-marine environments before the Late Jurassic diversification of the cypridocopine/cytherocopine modern ostracods.

The Great Gallery Rock Art Panel, Utah
Located along the cliffs of Horseshoe Canyon lies the Great Gallery, a spectacular rock art panel which is considered one of the "type" sites for the Barrier Canyon Style. This beautiful rock art can be seen at Canyonlands National Park, Utah. Images were taken from a distance, using a Canon 6D with a 105mm during a hike in November, 2016. Model is partial and will be added to soon. Source: Objaverse 1.0 / Sketchfab
