Wolves are back: Sociopolitical identity and opinions on management of Canis lupus

Joel Hartter & Lawrence Hamilton
In 2010 an interdisciplinary team of social and natural scientists began a project to study society–environment interactions in northeast Oregon. At first, the Communities and Forests in Oregon (CAFOR) project focused on Baker, Union and Wallowa Counties. Subsequently the project’s scope expanded to cover Crook, Grant, Umatilla and Wheeler Counties. One part of the CAFOR research involved a series of telephone surveys carried out in four stages over 2011 to 2018. The surveys employed consistent...

Bending and Looping of long DNA by Polycomb repressive complex 2 revealed by AFM imaging in liquid

Patrick Heenan, Anne Gooding, Xueyin Wang, Thomas Perkins & Thomas Cech
Polycomb repressive complex 2 (PRC2) is a histone methyltransferase that methylates histone H3 at Lysine 27. PRC2 is critical for epigenetic gene silencing, cellular differentiation, and the formation of facultative heterochromatin. It can also promote or inhibit oncogenesis. Despite this importance, the molecular mechanisms by which PRC2 compacts chromatin are relatively understudied. Here, we visualized the binding of PRC2 to naked DNA in liquid at the single-molecule level using atomic force microscopy. Analysis of the...

Data from: A quantitative inventory of yeast P body proteins reveals principles of composition and specificity

Wenmin Xing, Denise Muhlrad, Roy Parker & Michael K. Rosen
P bodies are archetypal biomolecular condensates that concentrate proteins and RNA without a surrounding membrane. While dozens of P body proteins are known, the concentrations of components in the compartment have not been measured. We used live cell imaging to generate a quantitative inventory of the major proteins in yeast P bodies. Only 7 proteins are highly concentrated in P bodies (5.1-15 uM); the 24 others examined are appreciably lower (most ≤ 2.6 uM). P...

Data from: A trait-based approach to assessing resistance and resilience to wildfire in two iconic North American conifers

Kyle Rodman, Thomas Veblen, Robert Andrus, Neil Enright, Joseph Fontaine, Angela Gonzalez, Miranda Redmond & Andreas Wion
Ongoing changes in fire activity have the potential to drive widespread shifts in Earth’s vegetation. Plant traits and vital rates can be indicators of the ability of individuals to survive fire (resistance) and populations to persist (resilience) following fire and provide a method to assess vulnerability to fire-driven vegetation shifts. In 15 study sites spanning climatic gradients in the southern Rocky Mountains, U.S.A., we quantified variation in key traits and vital rates of two co-occurring,...

E. coli aminoglycoside treatment

Joel Kralj & Giancarlo Bruni
Aminoglycosides are broad-spectrum antibiotics whose mechanism of action is under debate. It is widely accepted that membrane voltage potentiates aminoglycoside activity, which is ascribed to voltage-dependent drug uptake. In this paper, we measured the response of Escherichia coli treated with aminoglycosides and discovered that the bactericidal action arises not from the downstream effects of voltage dependent drug uptake, but rather directly from dysregulated membrane potential. In the absence of voltage, aminoglycosides are taken into cells...

Age predicts risky investment better than residual reproductive value

David Delaney, Luke Hoekstra & Fredric Janzen
Life-history theory predicts that investment into reproduction should increase as future reproductive opportunities (i.e., residual reproductive value, RRV) decrease. Researchers have thus intuitively used age as a proxy for RRV and assume RRV decreases with age when interpreting age-specific investment. Yet, age is an imperfect proxy for RRV and may even be a poor correlate in some systems. We used a 30-year study of the nesting ecology of painted turtles ( Chrysemys picta ) to...

Weather variation affects the dispersal of grasshoppers beyond their elevational ranges

Cesar Nufio, Andrew Prinster & Julian Resasco
Understanding how abiotic conditions influence dispersal patterns of organisms is important for understanding the degree to which species can track and persist in the face of changing climate. The goal of this study was to understand how weather conditions (temperature, precipitation and wind patterns) influence the dispersal patterns of multiple non-migratory grasshopper species from lower elevation grassland habitats in which they ­­complete their life-cycles to higher elevations that extend beyond their range limits. The study...

Data from: Genomic regions underlying metabolic and neuronal signaling pathways are temporally consistent outliers in a moving avian hybrid zone

Dominique Wagner, Robert Curry, Nancy Chen, Irby Lovette & Scott Taylor
The study of hybrid zones can provide insight into the genetic basis of species differences that are relevant for the maintenance of reproductive isolation. Hybrid zones can also provide insight into climate change, species distributions, and evolution. The hybrid zone between black-capped chickadees (Poecile atricapillus) and Carolina chickadees (P. carolinensis) is shifting northward in response to increasing winter temperatures but is not increasing in width. This pattern indicates strong selection against chickadees with admixed genomes....

Genomic variation in the American pika: signatures of geographic isolation and implications for conservation

Kelly B. Klingler, Joshua P. Jahner, Thomas L. Parchman, Chris Ray & Mary M. Peacock
Distributional responses by alpine taxa to repeated, glacial-interglacial cycles throughout the last two million years have significantly influenced the spatial genetic structure of populations. These effects have been exacerbated for the American pika (Ochotona princeps), a small alpine lagomorph constrained by thermal sensitivity and a limited dispersal capacity. As a species of conservation concern, long-term lack of gene flow has important consequences for landscape genetic structure and levels of diversity within populations. Here, we use...

Parasite exposure and host susceptibility jointly drive the emergence of epidemics

Tara Stewart Merrill, Spencer Hall & Carla Cáceres
Parasite transmission is thought to depend on both parasite exposure and host susceptibility to infection; however, the relative contribution of these two factors to epidemics remains unclear. We used interactions between an aquatic host and its fungal parasite to evaluate how parasite exposure and host susceptibility interact to drive epidemics. In six lakes, we tracked the following factors from pre-epidemic to epidemic emergence: 1) parasite exposure (measured observationally as fungal spores attacking wild-caught hosts), 2)...

Latitudinal gradients in population growth do not reflect demographic responses to climate

Megan Peterson, Graham Bailes, Lauren Hendricks, Laurel Pfeifer-Meister, Paul Reed, Scott Bridgham, Bart Johnson, Robert Shriver, Ellen Waddle, Hannah Wroton, Daniel Doak, Bitty Roy & William Morris
Spatial gradients in population growth, such as across latitudinal or elevational gradients, are often assumed to primarily be driven by variation in climate, and are frequently used to infer species’ responses to climate change. Here, we use a novel demographic, mixed model approach to dissect the contributions of climate variables vs. other latitudinal or local site effects on spatiotemporal variation in population performance in three perennial bunchgrasses. For all three species, we find that performance...

Vascular plant community data for Northwest Territories, Canada

Jennifer Baltzer, Nicola Day, Alison White, Kirsten Reid, Geneviève Degré-Timmons, Steve Cumming, Michelle Mack, Merritt Turetsky, Xanthe Walker & Jill Johnstone
Climate change is altering disturbance regimes outside of historical norms, which can impact biodiversity by selecting for plants with particular traits. The relative impact of disturbance characteristics on plant traits and community structure may be mediated by environmental gradients. We aimed to understand how wildfire impacted understory plant communities and plant regeneration strategies along gradients of environmental conditions and wildfire characteristics in boreal forests. We established 207 plots (60m2) in recently burned stands and 133...

Data from: Disturbance detection in Landsat time series is influenced by tree mortality agent and severity, not by prior disturbance

Kyle Rodman, Robert Andrus, Thomas Veblen & Sarah Hart
Landsat time series (LTS) and associated change detection algorithms are useful for monitoring the effects of global change on Earth’s ecosystems. Because LTS algorithms can be easily applied across broad areas, they are commonly used to map changes in forest structure due to wildfire, insect attack, and other important drivers of tree mortality. But factors such as initial forest density, tree mortality agent, and disturbance severity (i.e., percent tree mortality) influence patterns of surface reflectance...

Shedding light: a phylotranscriptomic perspective illuminates the origin of photosymbiosis in marine bivalves

Jingchun Li, Sarah Lemer, Lisa Kirkendale, Rudiger Bieler, Colleen Cavanaugh & Gonzalo Giribet
Background: Photosymbiotic associations between metazoan hosts and photosynthetic dinoflagellates are crucial to the trophic and structural integrity of many marine ecosystems, including coral reefs. Although extensive efforts have been devoted to study the short-term ecological interactions between coral hosts and their symbionts, long-term evolutionary dynamics of photosymbiosis in many marine animals are not well understood. Within Bivalvia, the second largest class of mollusks, obligate photosymbiosis is found in two marine lineages: the giant clams (subfamily...

Vermivora photographs in plumage genomic study

Marcella Baiz, Gunnar Kramer, Henry Streby, Scott Taylor, Irby Lovette & David Toews
Hybrids with different combinations of traits can be used to identify the genomic regions that underlie phenotypic characters important to species identity and recognition. Here we explore links between genomic and plumage variation in Blue-winged Warbler x Golden-winged Warbler hybrids, which have traditionally been categorized into two discrete types. "Lawrence’s Warbler" hybrids are very yellow overall, similar to Blue-winged Warblers, but exhibit the black throat patch and face mask of Golden-winged Warblers. "Brewster’s Warbler" hybrids...
