Data from: Gobbling across landscapes: Eastern wild turkey distribution and occupancy-habitat associations

Christopher Pollentier, Michael Hardy, R. Scott Lutz, Scott Hull & Benjamin Zuckerberg
Extensive restoration and translocation efforts beginning in the mid-20th century helped to reestablish eastern wild turkeys (Meleagris gallopavo silvestris) throughout their ancestral range. The adaptability of wild turkeys resulted in further population expansion in regions that were considered unfavorable during initial reintroductions across the northern United States. Identification and understanding of species distributions and contemporary habitat associations are important for guiding effective conservation and management strategies across different ecological landscapes. To investigate differences in wild...

Evaluating how lethal management affects poaching of Mexican wolves

Francisco Santiago-Ávila, Naomi Louchouarn, David Parsons & Adrian Treves
Despite illegal killing (poaching) being the major cause of death among large carnivores globally, little is known about the effect of implementing lethal management policies on poaching. Two opposing hypotheses have been proposed in the literature: implementing lethal management may decrease poaching incidence (‘killing for tolerance’) or increase it (‘facilitated killing’). Here, we propose a test of two opposed hypotheses that poaching (reported and unreported) of Mexican grey wolves (Canis lupus baileyi) in Arizona and...

Complex interactions underlie the correlated evolution of floral traits and their association with pollinators in a clade with diverse pollination systems.

Jeffrey Rose & Kenneth Sytsma
Natural selection by pollinators is an important factor in the morphological diversity and adaptive radiation of flowering plants. Selection by similar pollinators in unrelated plants leads to convergence in floral morphology, or “floral syndromes.” Previous investigations into floral syndromes have mostly studied relatively small and/or simple systems; emphasizing vertebrate-pollination. Despite the importance of multiple floral traits in plant-pollinator interactions, these studies have examined few quantitative traits, so their co-variation and phenotypic integration have been underexplored....

GABAA presynaptic inhibition regulates the gain and kinetics of retinal output neurons

Jenna Nagy, Briana Ebbinghaus, Mrinalini Hoon & Raunak Sinha
Output signals of neural circuits, including the retina, are shaped by a combination of excitatory and inhibitory signals. Inhibitory signals can act presynaptically on axon terminals to control neurotransmitter release and regulate circuit function. However, it has been difficult to study the role of presynaptic inhibition in most neural circuits due to lack of cell-type specific and receptor-type specific perturbations. In this study, we used a transgenic approach to selectively eliminate GABAA inhibitory receptors from...

Complex trait‒environment relationships underlie the structure of forest plant communities

Andres Rolhauser, Donald Waller & Caroline Tucker
Traits differentially adapt plant species to particular conditions generating compositional shifts along environmental gradients. As a result, community-scale trait values show concomitant shifts, termed trait‒environment relationships. Trait‒environment relationships are often assessed by evaluating community-weighted mean (CWM) traits observed along environmental gradients. Regression-based approaches (CWMr) assume that local communities exhibit traits centered at a single optimum value and that traits do not covary meaningfully. Evidence suggests that the shape of trait‒abundance relationships can vary widely along...

Forest phenoclusters for Argentina based on vegetation phenology and climate

Eduarda Silveira, Volker Radeloff, Guillermo Martínez Pastur, Sebastián Martinuzzi, Natalia Politi, Leonidas Lizarraga, Luis Rivera, Gregorio Gavier-Pizarro, He Yin, Yamina Rosas, Noelia Calamari, María Navarro, Yanina Sica, Ashley Olah, Julieta Bono & Anna Pidgeon
Forest biodiversity conservation and species distribution modeling greatly benefit from broad-scale forest maps depicting tree species or forest types rather than just presence and absence of forest, or coarse classifications. Ideally, such maps would stem from satellite image classification based on abundant field data for both model training and accuracy assessments, but such field-data does not exist in many parts of the globe. However, different forest types and tree species differ in their vegetation phenology,...

Past agricultural land use affects multiple facets of ungulate antipredator behavior

Savannah Bartel & John Orrock
Antipredator behavior affects prey fitness, prey demography, and the strength of ecological interactions. Although predator-prey interactions increasingly occur in habitats that experience multiple forms of human-generated disturbance, it is unclear how different forms of disturbance might affect antipredator behavior. Fire is a contemporary disturbance that has dramatic effects on terrestrial habitats. Such habitats may have also experienced past disturbances, like agricultural land use, that leave lasting legacies on habitat structure (e.g., overstory and understory composition)....

Demographic History and Genomic Targets of Positive Selection in Giant Gough Mice

Peicheng Jing & Bret Payseur
A key challenge in understanding how natural selection operates is to identify the mutations and genes that make it possible. Positive selection on beneficial mutations distorts linked variation by altering the site frequency spectrum, the configuration of haplotypes, and population differentiation. By comparing patterns of sequence variation to neutral predictions across genomes, the targets of positive selection can be located. We applied this logic to an unusual population of house mice that shows phenotypic and...

Corticothalamic gating of population auditory thalamocortical transmission in mouse

Baher Ibrahim, Caitlin Murphy, Georgiy Yudintsev, Matthew I. Banks, Daniel A. Llano & Yoshitaka Shinagawa
The mechanisms that govern thalamocortical transmission are poorly understood. Recent data have shown that sensory stimuli elicit activity in ensembles of cortical neurons that recapitulate stereotyped spontaneous activity patterns. Here, we elucidate a possible mechanism by which gating of patterned population cortical activity occurs. In this study, sensory-evoked all-or-none cortical population responses were observed in the mouse auditory cortex in vivo and similar stochastic cortical responses were observed in a colliculo-thalamocortical brain slice preparation. Cortical...

Understanding degraded speech leads to perceptual gating of a brainstem reflex in human listeners

Heivet Hernandez Perez, Jason Mikiel-Hunter, David McAlpine, Sumitrajit Dhar, Sriram Boothalingam, Jessica J.M. Monaghan & Catherine M. McMahon
The ability to navigate “cocktail-party” situations by focussing on sounds of interest over irrelevant, background sounds is often considered in terms of cortical mechanisms. However, subcortical circuits such as the pathway underlying the medial olivocochlear (MOC) reflex modulate the activity of the inner ear itself, supporting the extraction of salient features from auditory scene prior to any cortical processing. To understand the contribution of auditory subcortical nuclei and the cochlea in complex listening tasks, we...

BAF155 Methylation Drives Metastasis By Hijacking Super-enhancers and Subverting Anti-tumor Immunity

Eui-Jun Kim, Peng Liu, Shengjie Zhang, Kristine Donahue, Yidan Wang, Jennifer Schehr, Serena Wolfe, Amber Dickerson, Li Lu, Lixin Rui, Xuehua Zhong, Kari Wisinski, Min Yu, Aussie Suzuki, Joshua Lang, Irene Ong & Wei Xu
Subunits of the chromatin remodeler SWI/SNF are the most frequently disrupted genes in cancer. However, how post-translational modifications (PTM) of SWI/SNF subunits elicit epigenetic dysfunction remains unknown. Arginine-methylation of BAF155 by coactivator-associated arginine methyltransferase 1 (CARM1) promotes triple negative breast cancer (TNBC) metastasis. Herein, we discovered the dual roles of methylated-BAF155 (me-BAF155) in promoting tumor metastasis: activation of super-enhanceraddicted oncogenes by recruiting BRD4, and repression of interferon / pathway genes to suppress host immune response....

Buffering lidocaine heightens aversion to cornual nerve injections in dairy calves

Cassandra Tucker & Sarah Adcock
It is best practice to numb the horn buds before disbudding dairy calves, which can be achieved by injecting lidocaine, a local anesthetic, around the cornual nerve. In humans, the acute pain that occurs upon injection of lidocaine can be reduced by neutralizing the pH of the solution with an alkalizing agent, such as sodium bicarbonate. We evaluated whether buffering lidocaine would reduce calves’ behavioral and physiological responses to cornual nerve blocks on the left...

Evidence for niche conservatism in alpine beetles under a climate-driven species pump model

Jillian Schat, Yi-Ming Weng, Roman Dudko, David Kavanaugh, Lan Luo & Sean Schoville
Aim Past glacial climate cycles have generated lineage diversity in alpine habitats, acting as a climate-driven species pump. It is not clear how much this process contributes to ecological diversification of alpine species. To examine this problem, we test patterns of genetic and phenotypic divergence in two co-distributed species complexes of flightless alpine ground beetles. Greater differentiation in ecologically-important functional traits would indicate that ecological selection is an outcome of oscillating climate change, whereas greater...

Phenotypic...

Data for: Perceived risk structures the space use of competing carnivores

Mauriel Rodriguez Curras, Emiliano Donadio, Arthur Middleton & Jonathan Pauli
Competition structures ecological communities. In carnivorans, competitive interactions are disproportionately costly to subordinate carnivores who must account for risk of interspecific killing when foraging. Accordingly, missed opportunity costs for meso-carnivores imposed by risk can benefit the smallest-bodied competitors. However, the extent to which the risk perpetuates into spatial partitioning in hierarchically structured communities remains unknown. To determine how risk-avoidance behaviors shape the space-use of carnivore communities, we studied a simple community of carnivores in northern...

Innovation and Growth with Financial, and Other, Frictions

Jonathan Chiu, Cesaire Meh & Randall Wright
The generation and implementation of ideas, or knowledge, is crucial for economic performance. We study this process in a model of endogenous growth with frictions. Productivity increases with knowledge, which advances via innovation, and with the exchange of ideas from those who generate them to those best able to implement them (technology transfer). But frictions in this market, including search, bargaining, and commitment problems, impede exchange and thus slow growth. We characterize optimal policies to...

Market Structure and the Diffusion of E-Commerce: Evidence from the Retail Banking Industry

Jason Allen, Robert Clark & Jean-François Houde
This paper studies the role that market structure plays in affecting the diffusion of electronic banking. Electronic banking (and electronic commerce more generally) reduces the cost of performing many types of transactions for firms. The full benefits for firms from adoption, however, only accrue once consumers begin to perform a significant share of their transactions online. Since there are learning costs to adopting the new technology firms may try to encourage consumers to go online...

Data from: Broad geographic sampling reveals predictable, pervasive, and strong seasonal adaptation in Drosophila

Heather E. Machado, Alan O. Bergland, Ryan Taylor, Susanne Tilk, Emily Behrman, Kelly Dyer, Daniel K. Fabian, Thomas Flatt, Josefa González, Talia L. Karasov, Iryna Kozeretska, Brian P. Lazzaro, Thomas JS Merritt, John E. Pool, Katherine O’Brien, Subhash Rajpurohit, Paula R. Roy, Stephen W. Schaeffer, Svitlana Serga, Paul Schmidt, Dmitri Petrov & Bernard Kim
To advance our understanding of adaptation to temporally varying selection pressures, we identified signatures of seasonal adaptation occurring in parallel among Drosophila melanogaster populations. Specifically, we estimated allele frequencies genome-wide from flies sampled early and late in the growing season from 20 widely dispersed populations. We identified parallel seasonal allele frequency shifts across North America and Europe, demonstrating that seasonal adaptation is a general phenomenon of temperate fly populations. Seasonally fluctuating polymorphisms are enriched at...

Plastic responses to hot temperatures homogenize riparian leaf litter, speed decomposition, and reduce detritivores

Joann Jeplawy, Hillary Cooper, Jane Marks, Richard Lindroth, Morgan Andrews, Zacchaeus Compson, Catherine Gehring, Kevin Hultine, Kevin Grady, Thomas Whitham, Gerard Allan & Rebecca Best
Efforts to maintain the function of critical ecosystems under climate change often begin with foundation species. In the southwestern US, cottonwood trees support diverse communities in riparian ecosystems that are threatened by rising temperatures. Genetic variation within cottonwoods shapes communities and ecosystems, but these effects may be modified by phenotypic plasticity, where genotype traits change in response to environmental conditions. Here, we investigated plasticity in Fremont cottonwood (Populus fremontii) leaf litter traits as well as...

Data from: Effects of Bark Beetle Outbreaks on Forest Landscape Pattern in the Southern Rocky Mountains, U.S.A.

Kyle Rodman, Robert Andrus, Cori Butkiewicz, Teresa Chapman, Nathan Gill, Brian Harvey, Dominik Kulakowski, Niko Tutland, Thomas Veblen & Sarah Hart
Since the late 1990s, extensive outbreaks of native bark beetles (Curculionidae: Scolytinae) have affected coniferous forests throughout Europe and North America, driving changes in carbon storage, wildlife habitat, nutrient cycling, and water resource provisioning. Remote sensing is a crucial tool for quantifying the effects of these disturbances across broad landscapes. In particular, Landsat time series (LTS) are increasingly used to characterize outbreak dynamics, including the presence and severity of bark beetle-caused tree mortality, though broad-scale...

A meta-analysis of tropical land-use change effects on the soil microbiome: emerging patterns and knowledge gaps

Emily J. Diaz-Vallejo
Modifications to vegetation and soil due to changes in land use have the potential to alter the soil microbiome, with consequences for carbon and nutrient cycling. Despite the important function of soil microorganisms, little is known about their response to land-use change, especially in tropical regions where current rates of land conversion are greatest. The aim of this meta-analysis was to examine how land-use change influences soil microbial properties in tropical ecosystems and to identify...
