Data from: Testing models of reciprocal relations between social influence and integration in STEM across the college years

Paul Hernandez, V. Bede Agocha, Lauren Carney, Mica Estrada, Sharon Lee, David Loomis, Michelle Williams & Crystal Park
The present study tests predictions from the Tripartite Integration Model of Social Influences (TIMSI) concerning processes linking social interactions to social integration into science, technology, engineering, and mathematics (STEM) communities and careers. Students from historically overrepresented groups in STEM were followed from their senior year of high school through their senior year in college. Based on TIMSI, we hypothesized that interactions with social influence agents (operationalized as mentor network diversity, faculty mentor support, and research...

Water availability drives fine root dynamics in a Eucalyptus woodland under elevated atmospheric CO2 concentration

Juan Piñeiro, Raul Ochoa-Hueso, John Drake, Mark Tjoelker & Sally Power
Fine roots are a key component of carbon and nutrient dynamics in forest ecosystems. Rising atmospheric [CO2] (eCO2) is likely to alter the production and activity of fine roots, with important consequences for forest carbon storage. Yet empirical evidence of the role of eCO2 in driving root dynamics in low-nutrient forested ecosystems is limited, particularly for grassy woodlands, an ecosystem type of global importance. We sampled fine roots across seasons over a two-year period to...

Data from: A new Devonian euthycarcinoid evidences the use of different respiratory strategies during the marine-to-terrestrial transition in the myriapod lineage

Pierre Gueriau, James C. Lamsdell, Roy A. Wogelius, Phillip L. Manning, Victoria M. Egerton, Uwe Bergmann, Loïc Bertrand & Julien Denayer
Myriapods were, together with arachnids, the earliest animals to occupy terrestrial ecosystems, by at least the Silurian. The origin of myriapods and their land colonization have long remained puzzling until euthycarcinoids, an extinct group of aquatic arthropods considered amphibious, were shown to be stem group myriapods, extending the lineage to the Cambrian and evidencing a marine-to-terrestrial transition. Although possible respiratory structures comparable to the air-breathing tracheal system of myriapods are visible in several euthycarcinoids, little...

Advancing Cancer Prevention Practice Facilitation Work in Rural Primary Care During COVID-19

Dannell Boatman, Susan Eason, Mary E. Conn, Summer Miller & Stephenie Kennedy-Rea
COVID-19 and the response to slow the virus spread in West Virginia (WV), including a statewide stay-at-home order, presented challenges to rural primary care clinics on the frontlines. These challenges affected critical quality improvement work, including cancer screening services. In this commentary, the authors present the results of a survey of WV primary care practices that highlight potential long-term implications and identifies opportunities for practice facilitators to partner with rural primary care clinics to address...

A new method for quantifying heterochrony in evolutionary lineages

James Lamsdell
The occupation of new environments by evolutionary lineages is frequently associated with morphological changes. This co-variation of ecotype and phenotype is expected due to the process of natural selection, whereby environmental pressures lead to the proliferation of morphological variants that are a better fit for the prevailing abiotic conditions. One primary mechanism by which phenotypic variants are known to arise is through changes in the timing or duration of organismal development resulting in alterations to...

Evolution and development at the origin of a phylum

Bradley Deline, Jeffery Thompson, Nicholas Smith, Samuel Zamora, Imran Rahman, Sarah Sheffield, William Ausich, Thomas Kammer & Colin Sumrall
Quantifying morphological evolution is key to determining the patterns and processes underlying the origin of phyla. We constructed a hierarchical morphological character matrix to characterize the radiation and establishment of echinoderm body plans during the early Paleozoic. This showed that subphylum-level clades diverged gradually through the Cambrian, and the distinctiveness of the resulting body plans was amplified by the extinction of transitional forms and obscured by convergent evolution during the Ordovician. Higher-order characters that define...

Convergence, parallelism, and function of extreme parietal callus in diverse groups of Cenozoic Gastropoda

Carlie Pietsch, Brendan Anderson, Lauren Maistros, Ethan Padalino & Warren Allmon
We use SEM imaging to examine the shell microstructure of fossil and living species in five families of caenogastropods (Strombidae, Volutidae, Olividae, Pseudolividae, and Ancillariidae) to determine whether parallel or convergent evolution is responsible for the development of a unique caenogastropod trait, the extreme parietal callus. The extreme parietal callus is defined as a substantial thickening of both the spire callus and the callus on the ventral shell surface such that it covers 50% or...

PERMANOVA results from Principal component analysis of avian hind limb and foot morphometrics and the relationship between ecology and phylogeny

Amanda Falk, James Lamsdell & Enpu Gong
Principal component analysis has been used to test for similarities in ecology and life habit between modern and fossil birds, however, the two main portions of the hindlimb—the foot and the long bone elements—have not been examined separately. We examine the potential links between morphology, ecology, and phylogeny through a synthesis of phylogenetic paleoecological methods and morphospace analysis. Both hindlimb morphologies and species’ ecologies exhibit extreme phylogenetic clumping, although these patterns are at least partially...

Data from: Functional diversity of decomposers modulates litter decomposition affected by plant invasion along a climate gradient

Junwei Luan, Shirong Liu, Siyu Li, Joann Whalen, Yi Wang, Jingxi Wang, Yanchun Liu, Wei Dong & Scott Chang
1. Litter decomposition is fundamental to carbon (C) and nutrient cycling in ecosystems, which could be altered by plant invasion. The impacts of plant invasion on litter decomposition are generally predicted by traits difference between leaf litters of invasive and non-invasive species. However, plant invasion not only changes litter composition, but might also increase the activity or change the functional diversity of decomposers to alter litter decomposition, which is barely studied, and the effect could...

Data from: Differences in distress: variance and production of American crocodile (Crocodylus acutus) distress calls in Belize

James Anderson, Miriam Boucher & Marisa Tellez
Acoustic communication of American Crocodiles (Crocodylus acutus) is relatively understudied. Our overall aim was to determine the acoustic structure of wild American Crocodile distress calls, distinguish call differences among size classes (hatchling, juvenile, sub-adult, and adult), and investigate call production on a gradient of human disturbance. American Crocodile distress calls have strong frequency modulation and are comprised of multiple harmonics in a downsweeping pattern. Measured parameters (total duration, first quartile duration, maximal frequency, first quartile...

Data from: Can variation in seed removal patterns of Neotropical pioneer tree species be explained by local ant community composition?

Selina Ruzi, Paul-Camilo Zalamea, Daniel Roche, Rafael Achury, James Dalling & Andrew Suarez
Many plants depend on animals for seed dispersal, and ants commonly fill this role. We examined if heterogeneity in ant community composition among sites, between above- and below-ground foraging guilds, or between seasons predicts observed variation in seed removal rates for 12 nonmyrmecochorous Neotropical pioneer tree species on Barro Colorado Island, Panama. We also investigated if ants associated with removing seeds differed in specific morphological characters from the larger ant community. We observed ant-seed interactions...

Genetic, morphological, and niche variation in the widely hybridizing Rhus integrifolia-Rhus ovata species complex

Craig Barrett, Joshua Lambert, Mathilda Santee, Brandon Sinn, Samuel Skibicki, Heather Stephens & Hana Thixton
Hybridization and introgression are common processes among numerous plant species that present both challenges and opportunities for studies of species delimitation, phylogenetics, taxonomy, and adaptation. Rhus integrifolia and R. ovata are two ecologically important shrubs native to the southwestern USA and Mexico, and are known to hybridize frequently, but the morphological, genetic, and ecological implications of hybridization in these species are poorly studied on a broad geographic scale. Analyses were conducted using leaf morphology, genetic...

Nexus-formatted text file of ISSR band presence/absence for 75 loci in Corallorhiza bentleyi

Craig Barrett
Mycoheterotrophic plants derive most or all carbon and nutrients from fungal partners and represent poorly understood components of forest biodiversity. Many are rare or endangered yet can be ecological indicators of forest ecosystem function due to their often highly specific fungal host requirements. One such species is the IUCN red-listed (‘vulnerable’), fully mycoheterotrophic orchid, Corallorhiza bentleyi. This recently described species is among the rarest plants in Appalachia, known from five counties in Virginia and West...

Leveraging Electronic Health Records Data for Enhanced Colorectal Cancer Screening Efforts

Adam D. Baus, Lauren E. Wright, Stephenie Kennedy-Rea, Mary E. Conn, Susan Eason, Dannell Boatman, Cecil Pollard, Andrea Calkins & Divya Gadde
Introduction: Colorectal cancer is the third most common type of cancer in the United States for men and women combined. While the current threat of disease nationally is significant, the majority of colorectal cancer cases and deaths could be prevented through established screening tests and guidelines. Within the Appalachian region and West Virginia in particular, colorectal cancer is a significant public health problem. A more systematic, comprehensive approach to preventing and controlling cancer is essential....

Data from: A search for technosignatures from 14 planetary systems in the Kepler field with the Green Bank Telescope at 1.15–1.73 GHz

Jean-Luc Margot, Adam H. Greenberg, Pavlo Pinchuk, Akshay Shinde, Yashaswi Alladi, Srinivas Prasad MN, M. Oliver Bowman, Callum Fisher, Szilard Gyalay, Willow McKibbin, Brittany Miles, Donald Nguyen, Conor Power, Namrata Ramani, Rashmi Raviprasad, Jesse Santana & Ryan S. Lynch
This dataset describes candidate signal detections obtained at the Green Bank Telescope in 2016 and reprocessed with the 2020 UCLA SETI Group data processing pipeline. Analysis of Kepler mission data suggests that the Milky Way includes billions of Earth-sized planets in the habitable zone of their host stars. Current technology enables the detection of technosignatures emitted from a large fraction of the Galaxy. We describe a search for technosignatures that is sensitive to Arecibo-class transmitters...
