Grey Literature : Plausible Applications for Distance Education Practices

Julia Gelfand
With distance education among the most dynamic elements in post-secondary education today and with changes in emerging instruction technologies breaking frontiers, new interpretations of copyright and creative site licensing of information, grey literature has an equally new potential for use in these structures. The "Innovation Diffusion" common in distance education is a parallel structure to developments in electronic publishing and alternative ways to distribute and treat grey literature. Connectivity remains the major challenge as distance...

Permeability of H2 in ice Ih

John Patterson & Eric Saltazman
Reconstructions of paleoatmospheric H2 using polar firn air and ice cores would lead to a better understanding of the H2 biogeochemical cycle and how it is influenced by climate change and human activity. H2 is a small, highly diffusive molecule, and its mobility in the ice matrix must be accounted for when intepreting polar firn air and ice core measurements. Previous work on the mobility of H2 in ice has focused on warm (272-273 K),...

Data from: Selection of floral traits by pollinators and seed predators during sequential life history stages

Diane Campbell, Mascha Bischoff, Robert Raguso, Heather Briggs & Paula Sosenski
Organismal traits often influence fitness via interactions with multiple species. That selection is not necessarily predictable from pairwise interactions, such as when interactions occur during different lifecycle stages. Theoretically, directional selection during two sequential episodes, e.g., pollination and seed survival, can generate quadratic or correlational selection for a set of traits that passes both selective filters. We compared strength of selection during pollination versus seed predation in the field and tested whether interactions with multiple...

Data from: True UV color vision in a female butterfly with two UV opsins

Adriana D. Briscoe & Susan D. Finkbeiner
In true color vision animals discriminate between light wavelengths, regardless of intensity, using at least two photoreceptors with different spectral sensitivity peaks. Heliconius butterflies have duplicate UV opsin genes, which encode ultraviolet and violet photoreceptors, respectively. In H. erato, only females express the ultraviolet photoreceptor, suggesting females (but not males) can discriminate between UV wavelengths. We tested the ability of H. erato, and two species lacking the violet receptor, H. melpomene and Eueides isabella, to...

Spatiotemporal analysis of wildfires in California from 2000 to 2019

Shu Li & Tirtha Banerjee
The environmental pollution, property losses and casualties caused by wildfires in California are getting worse by the year. To minimize the interference of wildfires on economic and social development, and formulate targeted mitigation strategies, it is imperative to understand the scale and extent of previous wildfire occurrences. In this study, we first investigated the temporal distributions of past wildfires in California divided by size and causes and analyzed the changes observed in the past two...

Data from: Unraveling the ecological and evolutionary impacts of a plant invader on the pollination of a native plant

Wilnelia Recart & Diane Campbell
Interactions between a native plant species and its pollinators, herbivores, or microbiome can be affected by the presence of non-native plant species. Non-native plant species are altering plant-pollinator interactions, yet we know little about how these non-native species influence natural selection. In addition, year-to-year variation in flowering could influence the impacts of non-native species on reproductive success in native plants and the strength and direction of pollinator-mediated selection. We examined whether the presence of the...

H2 in firn air from Megadunes, Antarctica

Eric Saltzman
This dataset contains two items: 1) firn air measurements of H2 from Megadunes, Antarctica. 2) atmospheric surface flask air measurements of H2 from NOAA GML, CSIRO, and AGAGE from 1991-2003 adjusted to a common calibration scale. Firn air was sampled at the Megadunes site in central Antarctica (80.78 °S, 124.49 °E, Alt: 2,283 m) Antarctica during January of 2004. A 3” diameter hole was bored to a depth of 70 m using an ice core...

Impact assessment of coastal marine range shifts to support proactive management

Amy Henry & Cascade Sorte
Climate change is reshuffling Earth’s biota as species ranges shift to track increasing habitat temperatures. While redistribution may be necessary for species persistence, there can also be impacts on existing communities upon arrival of novel, range-shifting species. Anticipating the beneficial versus deleterious impacts of range-shifting species is essential for determining whether active management is needed, which could include employing strategies from facilitation (eg managed relocation) to suppression (eg prevention/control). We employ an impact assessment protocol...

Climate-driven limits to future carbon storage in California's wildland ecosystems

Shane Coffield, Kyle Hemes, Charles Koven, Michael Goulden & James Randerson
Enhanced ecosystem carbon storage is a key component of many climate mitigation pathways. The State of California has set an ambitious goal of carbon neutrality by 2045, relying in part on enhanced carbon sequestration in natural and working lands. We used statistical modeling, including random forests and climate analogues, to explore the climate-driven challenges and uncertainties associated with the goal of long-term carbon sequestration in forests and shrublands. We found that seasonal patterns of temperature...

The effects of adaptation to urea on feeding rates and growth in Drosophila larvae

Laurence Mueller, Kathreen Bitner, Grant Rutledge & James Kezos
A collection of forty populations were used to study the phenotypic adaptation of Drosophila melanogaster larvae to urea laced food. A long-term goal of this research is to map genes responsible for these phenotypes. This mapping requires large numbers of populations. Thus, we studied fifteen populations subjected to direct selection for urea tolerance and five controls. In addition, we studied another twenty populations which had not been exposed to urea but were subjected to stress...

Teaching and Exposing Grey Literature: What the Information Profession Needs to Know

Julia Gelfand
GL takes on new meanings with publishers and individuals creating new products and releasing information in different ways. With several choices of release usually available in different formats, the difficulty once associated with publishing GL and the enormous expenses predicted for a relatively low volume, electronic publishing via html and pdf has created new models and opportunities. Information access in the global economy forces the information professional to be better aware of a wider spectrum...

Fibrin fiber fluctuation

Qingda Hu & Elliot Botvinick
Understanding force propagation through the fibrous extracellular matrix can elucidate how cells interact mechanically with their surrounding tissue. Presumably, due to elastic nonlinearities of the constituent filaments and their random connection topology, force propagation in fiber networks is quite complex, and the basic problem of force propagation in structurally heterogeneous networks remains unsolved. We report on a new technique to detect displacements through such networks in response to a localized force, using a fibrin hydrogel...

One-to-one orthologs between Danaus plexippus and other insect species

Jose Ranz, Pablo Gonzalez & Cei Abreu-Goodger
Ortholog identification was performed between the gene models annotated in Danaus plexippus, Bombyx mori, and Drosophila melanogaster. The D. plexippus sequences are from an assembly obtained from an individual that belonged to a monarch population found in Irapuato, Mexico. 1-to-1 orthologs were delineated as part of an analysis devised to determining the proportion of gene models with homology support in other Lepidoptera and D. melanogaster, and in relation to a previously published gene annotation of...

A study of gene expression, structure, and contractility of iPSC-Derived Cardiac Myocytes from a family with heart disease due to LMNA mutation

Mehrsa Mehrabi, Tessa A. Morris, Zixuan Cang, Cecilia H. H. Nguyen, Yutong Sha, Mira N. Asad, Nyree Khachikyan, Taylor L. Greene, Danielle M. Becker, Qing Nie, Michael V. Zaragoza & Anna Grosberg
Genetic mutations to the Lamin A/C gene (LMNA) can cause heart disease, but the mechanisms making cardiac tissues uniquely vulnerable to the mutations remain largely unknown. Further, patients with LMNA mutations have highly variable presentation of heart disease progression and type. In vitro patient-specific experiments could provide a powerful platform for studying this phenomenon, but the use of induced pluripotent stem cell-derived cardiomyocytes (iPSC-CM) introduces heterogeneity in maturity and function thus complicating the interpretation of...

Plain-text conversions of U.S. Final Environmental Impact Statements from 2013-2020

Tyler Scott, Nicholas Marantz & Nicola Ulibarri
Administrative procedures are intended to increase transparency and help agencies make better decisions. However, these requirements also increase agency workload. Understanding how public agencies satisfy procedural requirements is a critical facet of agency performance. This analysis focuses on the language agencies use in Environmental Impact Statements (EISs) required by the U.S. National Environmental Policy Act (NEPA) – specifically, the reuse of similar text within and between assessments. We synthesize theories of institutional isomorphism and bureaucratic...

Data from: Drivers and cascading ecological consequences of Gambusia affinis trait variation

Zachary Wood, Laura Lopez, Celia Symons, Rebecca Robinson, Eric Palkovacs & Michael Kinnison
Phenotypic trait differences among populations can shape ecological outcomes for communities and ecosystems. However, few studies have mechanistically linked heritable and plastic components of trait variation to generalizable processes of ecology, such as trophic cascades. Here we assess morphological and behavioral trait variation in nine populations of common-garden reared western mosquitofish (Gambusia affinis) from three distinct ancestral predator environments (three populations per environment), each reared in the presence and absence of predator cues. We then...

The Space in Between: Overlapping Narratives of Arrival and Departure in Armenian-American Literary and Visual Arts

Talar Chahinian
Having fled Lebanon during the Civil War of 1975-1990, New Jersey-based author, Vehanoush Tekian, the LA-based experimental filmmaker, Hrayr Eulmessekian, and LA-based photographer, Ara Madzounian return to Beirut as a figurative repository of layered trauma. In Tekian’s prose and poetry, Family Tree (1997), Of Nourishment and the Abyss (2000) and Dispersion Poems (2017), in Eulmessekian’s film Bruitage (2006), and in Madzounian’s Birds Nest: A Photographic Essay of Bourj Hammoud (2015), Beirut is presented as an...

Invasion and Global Change Meta-analysis Data

Bianca E. Lopez, Jenica M. Allen, Jeffrey S. Dukes, Jonathan Lenoir, Montserat Vila, Dana M. Blumenthal, Evelyn M. Beaury, Emily J. Fusco, Toni Lyn Morelli, Cascade J. B. Sorte & Bethany A. Bradley
We conducted a global meta-analysis to investigate invasions, abiotic global environmental changes, and their combined effects on native species, communities, and ecosystems.We searched the Web of Science Core Collection for articles and reviews that were available in English through September 30, 2020. Search terms were chosen to identify papers reporting impacts of invasions with one of six abiotic global environmental changes (GECs: warming, nitrogen deposition, O2 depletion, drought, CO2 addition, and altered pH). We assessed...

Untargeted metabolomics molecular features data for plasma of 20 Peromyscus leucopus and 20 Mus musculus treated with LPS or controls

Alan Barbour, Nurul Islam, Ana Milovic & John Belisle
Animals that are competent natural reservoirs of zoonotic diseases commonly suffer little morbidity from the pathogens they persistently harbor. The mechanisms of this infection tolerance and the trade-off costs are poorly understood. We used exposure to a single dose of lipopolysaccharide (LPS) endotoxin as an experimental model of inflammation to compare the responses of the cricentine rodent Peromyscus leucopus, the white-footed deermouse, to that of Mus musculus, the standard laboratory model for pathogenesis studies. Four...

Peromyscus WGCNA supplement

Gabriela Balderrama-Gutierrez, Ana Milovic, Ali Mortazavi & Alan Barbour
P. leucopus also (deer mouse) is a known reservoir for infectious disease such as lyme disease and it is able to survive infections that other rodent models cannot. In this paper we explore P. lecucopus transcriptomic response after LPS stimulus in blood, liver and spleen using RNA-seq and compare it to M. musculus response. When comparing gene response to LPS from different species and tissues, neutrophil associated terms are enriched in the P. leucopus response,...

Data for: Topological defects produce kinks in biopolymer filament bundles

Qingda Hu, Maximilian Grill, Elliot Botvinick, Wolfgang Wall, Valentin Slepukhin & Alex Levine
Bundles of stiff filaments are ubiquitous in the living world, found both in the cytoskeleton and in the extracellular medium. These bundles are typically held together by smaller cross-linking molecules. We demonstrate, analytically, numerically, and experimentally, that such bundles can be kinked, that is, have localized regions of high curvature that are long-lived metastable states. We propose three possible mechanisms of kink stabilization: a difference in trapped length of the filament segments between two cross-links,...

Female differential allocation in response to extra-pair offspring and social mate attractiveness

Kerianne Wilson & Nancy Burley
Renewed debate over what benefits females might gain from producing extra-pair offspring emphasizes the possibility that apparent differences in quality between within-pair and extra-pair offspring are confounded by greater maternal investment in extra-pair offspring. Moreover, the attractiveness of a female’s social mate can also influence contributions of both partners to a reproductive attempt. Here we explore the complexities involved in parental investment decisions in response to extra-pair offspring and mate attractiveness with a focus on...
