In order to measure salinity gradients in the longitudinal, lateral, and vertical directions, a mesh of nine Ruskin RBR XR-420 CTDs and two Seabird SBE-37's were placed in various positions in all three dimensions. Lines 1, 2, 3, and 4 were placed in the channel. Lines 5 and 6 were placed in the shallows, lateral to line 2. Line 1 has two CTD's attached at the top and bottom of the water column. Lines 2...

Chronic Arsenic Exposure Impairs Adaptive Thermogenesis in Male C57BL/6J Mice

Felicia Castriota
The global prevalence of type 2 diabetes (T2D) has doubled since 1980. Human epidemiological studies support arsenic exposure as a risk factor for T2D, although the precise mechanism is unclear. We hypothesized that chronic arsenic ingestion alters glucose homeostasis by impairing adaptive thermogenesis, i.e. body heat production in cold environments. Arsenic is a pervasive environmental contaminant, with more than 200 million people worldwide currently exposed to arsenic-contaminated drinking water. Male C57BL/6J mice exposed to sodium...

Data from: Microbial functional diversity: from concepts to applications

Arthur Escalas, Lauren Hale, James Voordeckers, Yunfeng Yang, Mary Firestone, Lisa Alvarez-Cohen & Jizhong Zhou
Functional diversity is increasingly recognized by microbial ecologists as the essential link between biodiversity patterns and ecosystem functioning, determining the trophic relationships and interactions between microorganisms, their participation in biogeochemical cycles and their responses to environmental changes. Consequently, its definition and quantification have practical and theoretical implications. In this opinion paper, we present a synthesis on the concept of microbial functional diversity from its definition to its application. Initially, we revisit to the original definition...

Kinesin and dynein use distinct mechanisms to bypass obstacles

Luke S Ferro, Ahmet Yildiz, Sinan Can, Meghan A Turner & Mohamed M ElShenawy
Kinesin-1 and cytoplasmic dynein are microtubule (MT) motors that transport intracellular cargos. It remains unclear how these motors move along MTs densely coated with obstacles of various sizes in the cytoplasm. Here, we tested the ability of single and multiple motors to bypass synthetic obstacles on MTs in vitro. Contrary to previous reports, we found that mammalian dynein is highly capable of bypassing obstacles. Human kinesin-1 motors fail to avoid obstacles, consistent with their inability...

Habitat use, interspecific competition, and phylogenetic history shape the evolution of claw and toepad morphology in Lesser Antillean anoles

Michael Yuan, Catherine Jung, Marvalee Wake & Ian Wang
Ecologically functional traits are the product of several, at times opposing, selective forces. Thus, ecomorphological patterns can be disrupted locally by biotic interactions such as competition and may not be consistent across lineages. Here, we studied the evolution of claws and toepads in relation to macrohabitat (vegetation), use of structural microhabitat (perch height), and congeneric competition for two distantly-related Lesser Antillean anole clades: the bimaculatus and roquet series. We collect univariate and geometric morphometric data...

Data from: Differential patterns of floristic phylogenetic diversity across a post‐glacial landscape

Ida M. Mienna, James D.M. Speed, Mika Bendiksby, Andrew H. Thornhill, Brent D. Mishler & Michael D. Martin
Aim In this study, we explored spatial patterns of phylogenetic diversity (PD) and endemism in the flora of Norway and tested hypothesized post‐glacial environmental drivers of PD, including temperature, precipitation, edaphic factors and time since glacial retreat. Location Norway. Taxon Vascular plants (Trachaeophyta). 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 from: Species richness, endemism, and abundance patterns: tests of two fractal models in a serpentine grassland

Jessica Green, John Harte & Annette Ostling
From Ecology Letters: Although scaling relationships that characterize fractal species distributions offer an exciting potential for unification in biogeography, empirical support for fractal theory remains the subject of debate. We synthesize and test multiple predictions of two interrelated fractal models and a null model of random placement using Californian serpentine grassland data describing the spatial location of over 37 000 individually identified plants. The endemics–area relationship and species‐abundance distribution recently derived from a community‐level fractal...

Data from: Knock-on community impacts of a novel vector: spillover of emerging DWV-B from Varroa-infested honeybees to wild bumblebees

Robyn Manley, Ben Temperton, Toby Doyle, Daisy Gates, Sophie Hedges, Michael Boots & Lena Wilfert
Novel transmission routes can directly impact the evolutionary ecology of infectious diseases, with potentially dramatic effect on host populations and knock-on effects on the wider host community. The invasion of Varroa destructor, an ectoparasitic viral vector in Western honeybees, provides a unique opportunity to examine how a novel vector affects disease epidemiology in a host community. This specialist honeybee mite vectors deformed wing virus (DWV), an important re-emerging honeybee pathogen that also infects wild bumblebees....

Data from: Stochastic character mapping of state-dependent diversification reveals the tempo of evolutionary decline in self-compatible Onagraceae lineages

William A Freyman & Sebastian Höhna
A major goal of evolutionary biology is to identify key evolutionary transitions that correspond with shifts in speciation and extinction rates. Stochastic character mapping has become the primary method used to infer the timing, nature, and number of character state transitions along the branches of a phylogeny. The method is widely employed for standard substitution models of character evolution. However, current approaches cannot be used for models that specifically test the association of character state...

Personal thermal comfort models with wearable sensors

Shichao Liu, Stefano Schiavon, Hari Prasanna Das, Ming Jin & Costas Spanos
A personal comfort model is an approach to thermal comfort modeling, for thermal environmental design and control, that predicts an individual’s thermal comfort response, instead of the average response of a large population. We developed personal thermal comfort models using lab grade wearable in normal daily activities. We collected physiological signals (e.g., skin temperature, heart rate) of 14 subjects (6 female and 8 male adults) and environmental parameters (e.g., air temperature, relative humidity) for 2-4...

Berkeley High Resolution (BEHR) OMI NO2 v3.0C - Native pixels, daily profiles

Qindan Zhu, Josh Laughner & Ron Cohen
The BEHR reprocesses tropospheric NO2 columns from the Ozone Monitoring Instrument (OMI) satellite using high resolution a priori NO2 profiles, surface reflectivity, and surface elevation data. This product uses NO2 profiles for the day retrieved, simulated by the WRF-Chem model at 12 km spatial resolution. The use of high spatial resolution NO2 profiles has been shown to better resolve urban/rural differences in NO2 column densities, and the use of day-to-day (rather than monthly average) profiles...

David Hanifi, Noah Bronstein, Brent Koscher, Zach Nett, Joseph Swabeck, Kaori Takano, Adam Schwartzberg, Lorenzo Maserati, Koen Vandewal, Yoeri Van De Burgt, Alberto Salleo & Paul Alivisatos
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...

Supporting data for \"Direct observation of changing NOx lifetime in North American cities\"

Joshua Laughner & Ronald Cohen
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: Spider webs, stable isotopes and molecular gut content analysis: multiple lines of evidence support trophic niche differentiation in a community of Hawaiian spiders

Susan 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,...

Data from: Differential gene expression in relation to mating system in Peromyscine rodents

Jesyka Melendez-Rosa, Ke Bi & Eileen A. Lacey
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: Anacapa Toolkit: an environmental DNA toolkit for processing multilocus metabarcode datasets

Emily 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...

Ancestral male recombination in Drosophila albomicans produced geographically restricted neo-Y chromosome haplotypes varying in age and onset of decay

Kevin 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...

Data from: Tropical arboreal ants form dominance hierarchies over nesting resources

Senay Yitbarek & Stacy M. Philpott
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...

Shape-controlled single-crystal growth of InP at low temperatures down to 220 ℃

Der-Hsien Lien, Mark Hettick, Hao Li, Ali Javey, Matthew Yeh, Tzu-Yi Yang, Niharika Gupta, Matin Amani, Daryl Chrzan & Yu-Lun Chueh
III-V compound semiconductors are widely used for electronic and optoelectronic applications. However, interfacing III-Vs with other materials has been fundamentally limited by the high growth temperatures and lattice-match requirements of traditional deposition processes. Recently, we developed the templated liquid phase (TLP) crystal growth method for enabling direct growth of shape-controlled single crystal III-Vs on amorphous substrates. Although in theory, the lowest temperature for TLP growth is that of the melting point of the group III...
