Data from: Hurricane effects on Neotropical lizards span geographic and phylogenetic scales

Colin Donihue, Alex Kowaleski, Jonathan Losos, Adam Algar, Simon Baeckens, Robert Buchkowski, Anne-Claire Fabre, Hannah Frank, Anthony Geneva, Graham Reynolds, James Stroud, Julián Velasco, Jason Kolbe, Luke Mahler & Anthony Herrel
Extreme climate events such as droughts, cold snaps, and hurricanes can be powerful agents of natural selection, producing acute selective pressures very different from the everyday pressures acting on organisms. However, it remains unknown whether these infrequent but severe disruptions are quickly erased by quotidian selective forces, or whether they have the potential to durably shape biodiversity patterns across regions and clades. Here, we show that hurricanes have enduring evolutionary impacts on the morphology of...

The potential for low-grade metamorphism to facilitate fault instability in a geothermal reservoir

Mengke An, Fengshou Zhang, Ki-Bok Min, Derek Elsworth, Chris Marone & Changrong He
Swarms of earthquakes during shale gas exploitation in the Changning area of the Sichuan Basin indicate that hydraulic fracturing induces seismicity both within the target reservoir formation but also to depths of several kilometers below the horizontal well. These remote earthquakes are possibly triggered by total stress perturbations resulting from the hydraulic fracturing. We use a dislocation-based analytical model to simulate multistage hydraulic fracturing of three horizontal wells at a single well pad to explore...

This is a place and name redacted dataset of 60 qualitative interviews of those who have been affected by the opioid crisis. Individuals fit into one of four categories: (1) individuals in recovery from an opioid use disorder; (2) individuals who have lost a loved one due to an opioid overdose; (3) individuals who have supported a loved one through their opioid use; and (4) individuals who are pain management patients who have faced obstacles...

Modeled dataset for the estimation of atmospheric transport errors using a Multi-Physics and Analysis Ensemble on the Midwest US

L.I. Diaz-Isaac, T. Lauvaux & K.J. Davis
Atmospheric inversions are used to assess biosphere-atmosphere CO2 surface exchanges. However, large uncertainties exist among inverse flux estimates independent of the spatial scales. Atmospheric transport model errors are one of the main contributors to the uncertainty affecting CO2 inverse flux estimates but have not been quantified thoroughly. The model dataset archived here were used to evaluate atmospheric transport errors over the US upper Midwest with an ensemble of simulations created with the Weather Research and...

One-way nested (27km, 9km and 3km) model output of North American atmospheric CO2 simulation (full WRF-chem output)

A. Samaddar, S. Feng, T. Lauvaux, Z.R. Barkley, S. Pal & K.J. Davis
Synoptic weather systems are a major driver of spatial gradients in atmospheric CO2 mole fractions. During frontal passages air masses from different regions meet at the frontal boundary creating significant gradients in CO2 mole fractions. This study quantitatively describes the atmospheric transport of CO2 mole fractions during a mid-latitude cold front passage and explores the impact of various sources of CO2. We focus here on a cold front passage over Lincoln, Nebraska on August 4th,...

Implications of electron detachment in associative collisions of atomic oxygen anion with molecular nitrogen for modeling of transient luminous events

R. Janalizadeh & V.P. Pasko
Electron detachment from negative ion of atomic oxygen, O-, is important for understanding of lightning-induced upper atmospheric discharges. Contrary to previous studies, Rayment and Moruzzi [1978] argue that the associative detachment reaction of O- with molecular nitrogen, N2, proceeds with N2 in its ground state, and calculate the reaction rate coefficient as a function of the reduced electric field. In this work we analyze the experimental setup in [Rayment and Moruzzi, 1978] and demonstrate that...

Dataset of Constraining fossil fuel CO2 emissions from urban area using OCO-2 observations of total column CO2

X. Ye, T. Lauvaux, E.A. Kort, T. Oda, S. Feng, J.C. Lin, E.G. Yang & D. Wu
Satellite observations of the total column dry-air CO2 (XCO2) are expected to support the quantification and monitoring of fossil fuel CO2 (ffCO2) emissions from urban areas. We evaluate the utility of the Orbiting Carbon Observatory 2 (OCO-2) XCO2 retrievals to optimize whole-city emissions, using a Bayesian inversion system and high-resolution transport modeling. The uncertainties of constrained emissions related to transport model, satellite measurements, and local biospheric fluxes are quantified. For the first two uncertainty sources,...

Coral accurately bridges paired-end reads alignment

Q. Shi & M. Shao
Motivation: The established high-throughput RNA-seq technologies usually produce paired-end reads. A challenging problem is therefore to computationally infer the alignment of entire fragments given the alignment of the two mate ends. Solving this problem essentially provide longer RNA-seq reads, and hence benefits downstream RNA-seq analysis. Results: We introduce Coral, a new tool that can accurately bridge paired-end RNA-seq reads. The core of Coral is a novel optimization formulation that can capture the most reliable bridging...

Data from: Fruit traits of pioneer trees structure seed dispersal across distances on tropical deforested landscapes: implications for restoration

Paulo H. S. A. Camargo, Marco A. Pizo, Pedro H. S. Brancalion & Tomás A. Carlo
Pioneer trees with fleshy fruits are typically planted in restoration projects to attract frugivores as a mean to increase dispersal and accelerate forest regeneration. However, differences in fruit traits of pioneer trees can potentially influence dispersal and their restoration outcomes. Here we investigated the effects of bird and plant traits, and distance to forest fragments, on the seed rain using a tree-planting experiment replicated in 12 deforested sites in Brazil. Factors were fruit traits of...

Data from: Introduced bees (Osmia cornifrons) collect pollen from both coevolved and novel host-plant species within their family-level phylogenetic preferences

Anthony Vaudo, David Biddinger, Wiebke Sickel, Alexander Keller & Margarita M Lopez-Uribe
Studying the pollen preferences of introduced bees allows us to investigate how species utilize host-plants when establishing in new environments. Osmia cornifrons is a solitary bee introduced into North America from East-Asia for pollination of crops in the Rosaceae. We investigated whether O. cornifrons 1) more frequently collected pollen from host-plant species they coevolved with from their geographic origin, or 2) prefer hosts-plant species of specific plant taxa independent of origin. To address this question,...

Data from: Crop production in the USA is frequently limited by a lack of pollinators

James Reilly, Derek Artz, David Biddinger, Kyle Bobiwash, Natalie Boyle, Claire Brittain, Julia Brokaw, Josh Campbell, Jaret Daniels, Elizabeth Elle, Jamie Ellis, Shelby Fleischer, Jason Gibbs, Robert Gillespie, Knute Gundersen, Larry Gut, George Hoffman, Neelendra Joshi, Ola Lundin, Keith Mason, Carley McGrady, Steve Peterson, Theresa Pitts-Singer, Sujaya Rao, Nikki Rothwell … & Rachael Winfree
Most of the world’s crops depend on pollinators, so declines in both managed and wild bees raise concerns about food security. However, the degree to which insect pollination is actually limiting current crop production is poorly understood, as is the role of wild species (as opposed to managed honey bees) in pollinating crops, particularly in intensive production areas. We established a nation-wide study to assess the extent of pollinator limitation in seven crops at 131...

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...

Data from: How gut microbiome interactions affect nutritional traits of Drosophila melanogaster

, Grace Peters-Schulze, Jingwei Cai, Andrew D. Patterson & Angela E. Douglas
Most research on the impact of the gut microbiome on animal nutrition is designed to identify the effects of single microbial taxa and single metabolites of microbial origin, without considering the potentially complex network of interactions among co-occurring microorganisms. Here, we investigate how different microbial associations and their fermentation products affect host nutrition, using Drosophila melanogaster colonized with three gut microorganisms (the bacteria Acetobacter fabarum and Lactobacillus brevis and the yeast Hanseniaspora uvarum) in all...

Ecosystem services enhanced through soundscape management link people and wildlife

Mitch Levenhagen, Zachary Miller, Alissa Petrelli, Lauren Ferguson, Yau-Huo Shr, Dylan Gomes, Derrick Taff, Crow White, Kurt Fristrup, Christopher Monz, Christopher McClure, Peter Newman, Clinton Francis & Jesse Barber
Burgeoning urbanization, development and human activities have led to reduced opportunities for nature experience in quiet acoustic environments. Increasing noise affects both humans and wildlife alike. We experimentally altered human-caused sound levels in a paired study using informational signs that encouraged quiet behaviours in week-on, week-off blocks on the trail system of Muir Woods National Monument, California, USA to test if the soundscape influences both wildlife and human experiences. Using continuous measurements from acoustic recording...

Population decline of a long-distance migratory passerine at the edge of its range: nest predation, nest replacement, and immigration

Michael Murphy, Lucas Redmond, Amy Dolan, Nathan Cooper, Christopher Chutter & Sarah Cancellieri
The relative importance of predators and resources (i.e., food) for the dynamics of migratory bird populations is poorly known. Resource availability may be more likely in resource poor environments, but given that nest failure in most systems is due mainly to predation, predator effects may predominate. We document a rapid decline of an isolated Eastern Kingbird (Tyrannus tyrannus) population breeding in the Great Basin Desert of eastern Oregon, USA, and evaluate whether it was driven...

Human-dominated landcover corresponds to spatial variation in Mourning Dove reproductive output across the United States.

David Munoz & David Miller
Studies examining impacts of land cover typically focus on abundance, distribution, and/or community richness, overlooking underlying demographic processes such as survival or reproduction. Here, we present findings from a unique dataset that allowed us to measure the relationship between land cover and reproductive output across the distribution of the Mourning Dove (Macroura zenaida). We used hunter-derived, Mourning Dove wing data across 1,271 counties in the United States from 2008 to 2014 to estimate spatially explicit...

Data from: Mob and rotational grazing influence pasture biomass, nutritive value, and species composition

Eric Billman, Jessica WIlliamson, Kathy Soder, Danielle Andreen & R. Skinner
This is digital research data corresponding to a published manuscript, Mob and rotational grazing influence pasture biomass, nutritive value, and species composition, in Agronomy Journal, Vol. 112 p. 2866-2878. Mob grazing, which uses very high stocking densities for short durations followed by a relatively long rest period, was designed to mimic bison (Bison bison) grazing in western U.S. grassland. This project assessed the suitability of mob grazing for livestock production in the Northeast. Objectives were...

Improved 2-D grounding-line orientation in an ice-sheet model.

D. Pollard & R. DeConto
The use of a boundary-layer parameterization of buttressing and ice flux across grounding lines in a two-dimensional ice-sheet model is improved by allowing general orientations of the grounding line. This and another modification to the model's grounding-line parameterization are assessed in two settings: a narrow fjord-like domain (MISMIP+), and in future simulations of West Antarctic ice retreat under RCP8.5-based climates. The new modifications are found to have significant effects on the fjord results, which are...

Modelling of streamer ignition and propagation in the system of two approaching hydrometeors

J. Jansky & V.P. Pasko
First principles plasma fluid modeling is used for investigation of electrical gas discharges ignited by a configuration of two approaching conducting hydrometeors with typical radii on the order of several millimeters under thunderstorm conditions (i.e., at an elevated location in the Earth's atmosphere corresponding to half of air density at ground level and at applied electric field approximately half of that required for avalanche multiplication of electrons in air). It is demonstrated that UV photons...

Exploring the landscape of model representations

K. Kidder & W.G. Noid
The success of any physical model critically depends upon adopting an appropriate representation for the phenomenon of interest. Unfortunately, it remains generally challenging to identify the essential degrees of freedom or, equivalently, the proper order parameters for describing complex phenomena. Here we develop a statistical physics framework for exploring and quantitatively characterizing the space of order parameters for representing physical systems. Specifically, we examine the space of low-resolution representations that correspond to particle based coarse-grained...
