Identification of Wright fishhook cactus using drone and remote sensing technology

Steven Petersen
Obtaining accurate population estimates of plants has been an integral part of the listing, recovery, and delisting of species under the U.S. Endangered Species Act (ESA) of 1973 and for monitoring vegetation in response to livestock grazing management. However, obtaining such estimates for many plant species remains a daunting and labor-intensive task. The use of small unmanned aircraft systems (sUAS or drones) may provide an effective alternative to ground surveys for rare and endangered plants....

Improving dryland seedling recruitment using fungicide seed coatings

Benjamin Hoose, Brad Geary, William Richardson, Steven Petersen & Matthew Madsen
The success of seed-based restoration in dryland regions of the world is often low or sporadic, with most mortality occurring between germination and emergence. Fungal pathogenesis is one process that may reduce seedling emergence and limit restoration success. Our objective was to determine whether fungicide seed coatings constitute an economically viable strategy for increasing emergence by reducing fungal pathogenesis and mortality. We performed an experiment across two sites and three years, using bluebunch wheatgrass (Pseudoroegneria...

Performance and social connection data for baseball and basketball from 2001 to 2020

Emily Evans, Benjamin Webb & Rebecca Jones
We examine whether social data can be used to predict how members of Major League Baseball (MLB) and members of the National Basketball Association (NBA) transition between teams during their career. We find that incorporating social data into various machine learning algorithms substantially improves the algorithms' ability to correctly determine these transitions in the NBA but only marginally in MLB. We also measure the extent to which player performance and team fitness data can be...

Data for a preliminary molecular phylogeny of the family Hydroptilidae (Trichoptera): exploring the combination of targeted enrichment data and legacy Sanger sequence data

Robin Thomson, Paul Frandsen & Ralph Holzenthal
The purpose of this study is to provide a proof-of-concept that the use of molecular data, particularly targeted enrichment data, and statistically supported methods of analysis can result in the construction of a stable phylogenetic framework for the microcaddisflies (Trichoptera: Hydroptilidae). Here, we use a combination of targeted enrichment data for ca. 300 nuclear protein-coding genes and legacy (Sanger-based) sequence data for the mitochondrial COI gene and partial sequence from the 28S rRNA gene.

The impact of Rhodiola Rosea on biomarkers of diabetes, inflammation, and microbiota in a leptin receptor-knockout mouse model

Robert Courville, Mahtab Jafari, Richard Van Etten, John Chaston, Jasmin Grace Juanson Arabit, Dara Kiani, Cindy Duy Nguyen, Nilamani Jena, Zhong-Ying Liu & Prasanthi Tata
Type 2 diabetes is the most prevalent endocrine disease in the world, and recently the gut microbiota have become a potential target for its management. Recent studies have illustrated that this disease may predispose individuals to certain microbiome compositions, and treatments like metformin have been shown to change gut microbiota and their associated metabolic pathways. However, given the limitations and side effects associated with pharmaceuticals currently being used for therapy of diabetes, there is a...

Environmental correlates of phenotypic evolution in ecologically diverse Liolaemus lizards

Danielle Edwards, Luciano Avila, Lorena Martinez, & Mariana Morando
Evolutionary correlations between phenotypic and environmental traits characterize adaptive radiations. However, the lizard genus Liolaemus, one of the most ecologically diverse terrestrial vertebrate radiations on earth, has so far shown limited or mixed evidence of adaptive diversification in phenotype. Restricted use of comprehensive environmental data, incomplete taxonomic representation and not considering phylogenetic uncertainty may have led to contradictory evidence. We compiled a 26 taxon dataset for the L. gracilis species group, representing much of the...

Negotiating mutualism: a locus for exploitation by rhizobia has a broad effect size distribution and context-dependent effects on legume hosts

Camille Wendlandt, Miles Roberts, Kyle Nguyen, Marion Graham, Zoie Lopez, Emily Helliwell, Maren Friesen, Joel Griffitts, Paul Price & Stephanie Porter
In mutualisms, variation at genes determining partner fitness provides the raw material upon which coevolutionary selection acts, setting the dynamics and pace of coevolution. However, we know little about variation in the effects of genes that underlie symbiotic fitness in natural mutualist populations. In some species of legumes that form root nodule symbioses with nitrogen-fixing rhizobial bacteria, hosts secrete nodule-specific cysteine-rich (NCR) peptides that cause rhizobia to differentiate in the nodule environment. However, rhizobia can...

Integrative biodiversity inventories: characterizing lichen-forming fungal diversity in Glen Canyon National Recreation Area using DNA barcoding and vouchered specimens

Steven Leavitt
The Colorado River and its tributaries on the Colorado Plateau are home to unique desert river ecosystems and changing environmental conditions. Within this region, the Glen Canyon National Recreation Area (GCNRA) is comprised of rugged, high desert terrain and is managed by the United States National Parks Service as both a recreational and conservation area. Despite the ecological and economic importance of GCNRA, significant components of the ecological communities therein remain poorly characterized, including lichens....

Reproductive allocation in Nicrophorus maliger and Nicrophorus guttula

Mark Belk, Peter Meyers & J. Curtis Creighton
Abstract: The cost of reproduction hypothesis suggests that allocation to current reproduction constrains future reproduction. How organisms accrue reproductive costs and allocate energy across their lifetime may differ among species adapted to different resource types. We test this by comparing lifetime reproductive output, patterns of reproductive allocation, and senescence between two species of burying beetles, Nicrophorus marginatus and N. guttula, that differ in body size, across a range of carcass sizes. These two species of...
