NOx lifetime can be directly observed from space, and has a nonlinear relationship with its own concentration. At high NOx concentrations, NOx lifetime decreases with decreasing concentration, but at intermediate concentrations, the reverse is true. Here we show that urban NOx lifetime in North America has changed between 2005 and 2014. The shape of these changes is qualitatively consistent with a steady-state model of NOx lifetime with decreasing NOx emissions. The pattern of change suggests...

Data from: Anacapa Toolkit: an environmental DNA toolkit for processing multilocus metabarcode datasetsEmily E. Curd, Zack Gold, Gaurav S. Kandlikar, Jesse Gomer, Max Ogden, Taylor O'Connell, Lenore Pipes, Teia M. Schweizer, Laura Rabichow, Meixi Lin, Baochen Shi, Paul H. Barber, Nathan Kraft, Robert Wayne & Rachel S. Meyer
1. Environmental DNA (eDNA) metabarcoding is a promising method to monitor species and community diversity that is rapid, affordable, and non-invasive. Longstanding needs of the eDNA community are modular informatics tools, comprehensive and customizable reference databases, flexibility across high-throughput sequencing platforms, fast multilocus metabarcode processing, and accurate taxonomic assignment. As bioinformatics tools continue to improve, addressing each of these demands within a single bioinformatics toolkit is becoming a reality. 2. Here we present an open...
Data from: Spider webs, stable isotopes and molecular gut content analysis: multiple lines of evidence support trophic niche differentiation in a community of Hawaiian spidersSusan Kennedy, Jun Ying Lim, Joanne Clavel, Henrik Krehenwinkel & Rosemary G. Gillespie
1. Adaptive radiations are typically characterized by niche partitioning among their constituent species. Trophic niche partitioning is particularly important in predatory animals, which rely on limited food resources for survival. 2. We test for trophic niche partitioning in an adaptive radiation of Hawaiian Tetragnatha spiders, which have diversified in situ on the Hawaiian Islands. We focus on a community of nine species belonging to two different clades, one web building and the other actively hunting,...

Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been used to explain species coexistence and community structure. However, it remains unclear whether or in what contexts dominance hierarchies occur in tropical ant communities. This study seeks to examine whether arboreal twig-nesting ants competing for nesting resources in a Mexican coffee agricultural ecosystem...
Ancestral male recombination in Drosophila albomicans produced geographically restricted neo-Y chromosome haplotypes varying in age and onset of decayKevin Wei & Doris Bachtrog
Male Drosophila typically have achiasmatic meiosis, and fusions between autosomes and the Y chromosome have repeatedly created non-recombining neo-Y chromosomes that degenerate. Intriguingly, Drosophila nasuta males recombine, but their close relative D. albomicans reverted back to achiasmy after evolving neo-sex chromosomes. Here we use genome-wide polymorphism data to reconstruct the complex evolutionary history of neo-sex chromosomes in D. albomicans and examine the effect of recombination and its cessation on the initiation of neo-Y decay. Population...
Herin is the code and example data sets for the publication titled: "Redefining Near-Unity Luminescence in Quantum Dots with Photothermal Threshold Quantum Yield." The abstract of this paper is as follows. A variety of optical applications rely on the absorption and reemission of light. The quantum yield of this process often plays an essential role. When the quantum yield deviates from unity by significantly less than 1%, applications such as luminescent concentrators and optical refrigerators...
Behaviors that increase an individual's exposure to pathogens are expected to have important effects on immunoactivity. Because sexual reproduction typically requires close contact among conspecifics, mating systems provide an ideal opportunity to study the immunogenetic correlates of behaviors with high versus low risks of pathogen exposure. Despite logical links between polygynandrous mating behavior, increased pathogen exposure, and greater immunoactivity, these relationships have seldom been examined in nonhuman vertebrates. To explore interactions among these variables in...
Data from: The 15-year post-treatment response of a mixed-conifer understory plant community to thinning and burning treatmentsMatthew Hurteau, Marrissa Goodwin, Malcolm North, Harold Zald & Brandon Collins
Disturbance is central to maintaining diversity in forest ecosystems. In the dry forests of the western United States, over a century of fire exclusion has altered the fire regimes of these forests, resulting in high fuel loads and a loss of plant diversity. Mechanical thinning and prescribed fire are widely used to restore structural complexity and species diversity in many western U.S. forests. While studies have shown that the reintroduction of fire into these forests...

Videos of Gold Nanorods Etching in Graphene Liquid Cell Transmission Electron Microscopy- 42 mM FeCl3Matthew Hauwiller, Justin Ondry & A. Paul Alivisatos
Premade gold nanorods were etched in a graphene liquid cell and imaged using Transmission Electron Microscopy (TEM). An aqueous solution of gold nanorods, Tris Buffer-HCl, and FeCl3 was encapsulated between graphene sheets. The final concentration of FeCl3 was 42 mM. Through a combination of the electron beam-generated radiolysis products and the FeCl3, the nanorods underwent non-equilibrium etching. See associated papers for more details.

Animal signals experience selection for detectability, which is determined in large part by the signal transmission properties of the habitat. Understanding the ecological context in which communication takes place is therefore critical to understanding selection on the form of communication signals. In order to determine the influence of environmental heterogeneity on signal transmission, we focus on a wolf spider species native to central Florida, Schizocosa floridana, in which males court females using a substrate-borne vibratory...
Methods: We produced a multi-locus Maximum Likelihood (ML) phylogeny using a combination of newly produced DNA sequences from herbarium specimens and sequences available from public repositories. We combined the phylogeny with species occurrence data to estimate phylogenetic diversity and phylogenetic endemism across Norway, using a spatial randomization to judge statistical significance. We used multiple-model inference to identify environmental variables that contributed the most to the patterns of phylogenetic diversity. Finally, we estimated phylogenetic turnover and...
Data from: Comparative landscape genetics reveals the evolution of viviparity reduces genetic connectivity in fire salamandersAndré Lourenço, João Gonçalves, Filipe Carvalho, Ian J Wang & Guillermo Velo Antón
Evolutionary changes in reproductive mode may affect co-evolving traits, such as dispersal, though this subject remains largely underexplored. The shift from aquatic oviparous or larviparous reproduction to terrestrial viviparous reproduction in some amphibians entails skipping the aquatic larval stage and, thus, greater independence from water. Accordingly, amphibians exhibiting terrestrial viviparous reproduction may potentially disperse across a wider variety of sub-optimal habitats and increase population connectivity in fragmented landscapes compared to aquatic-breeding species. We investigated this...
Data from: The environmental determinants of total evaporative water loss in birds at multiple temperaturesSoorim Song & Steven Beissinger
Endotherms dissipate heat to the environment to maintain a stable body temperature at high ambient temperatures, which requires them to maintain a balance between heat dissipation and water conservation. Birds are relatively small, contain a large amount of metabolically expensive tissue, and are mostly diurnal, making them susceptible to physiological challenges related to water balance and heat dissipation. We compiled total evaporative water loss (TEWL) measurements for 172 species of birds exposed to different temperatures...
Temporal Inflection Points in Decorated Pottery: a Bayesian Refinement of the Late Formative Chronology in the Southern Lake Titicaca Basin, BoliviaChristine Hastorf, Erik Marsh, Andrew Roddick, Maria Bruno, Scott Smith & John Janusek
The Late Formative Period immediately precedes the emergence of Tiwanaku, one of the earliest South American states, yet is one of the most poorly understood periods in the southern Lake Titicaca Basin (Bolivia). In this paper, we refine this period’s ceramic chronology with large sets of dates from eight sites, focusing on temporal inflection points in decorated ceramic styles. These points, estimated here by Bayesian models, index specific moments of change: (1) cal AD 140...
