Data from: The effects of microhabitat specialization on mating communication in a wolf spider

Malcolm F. Rosenthal, Eileen A. Hebets, Benji Kessler, Rowan McGinley & Damian O. Elias
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...

Data from: Comparative landscape genetics reveals the evolution of viviparity reduces genetic connectivity in fire salamanders

André 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...

Videos of Gold Nanorods Etching in Graphene Liquid Cell Transmission Electron Microscopy- 42 mM FeCl3

Matthew 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.

Temporal Inflection Points in Decorated Pottery: a Bayesian Refinement of the Late Formative Chronology in the Southern Lake Titicaca Basin, Bolivia

Christine 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...

Data from: The environmental determinants of total evaporative water loss in birds at multiple temperatures

Soorim 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...

Multiple sequence alignment for the native Norwegian vascular plant phylogeny

Ida M. Mienna, James D.M. Speed, Mika Bendiksby, Andrew H. Thornhill, Brent D. Mishler & Michael D. Martin
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: 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...

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....

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...

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...

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...

The many population genetic and demographic routes to islands of genomic divergence

Claudio Quilodrán, Kristen Ruegg, Ashley Sendell-Price, Eric Anderson, Tim Coulson & Sonya Clegg
The way that organisms diverge into reproductively isolated species is a major question in biology. The recent accumulation of genomic data provides promising opportunities to understand the genomic landscape of divergence, which describes the distribution of differences across genomes. Genomic areas of unusually high differentiation have been called genomic islands of divergence. Their formation has been attributed to a variety of mechanisms, but a prominent hypothesis is that they result from divergent selection over a...

Data from: Genome-wide epigenetic isolation by environment in a widespread Anolis lizard

Ian Wang, Guinevere Wogan, Michael Yuan & D. Luke Mahler
Epigenetic changes can provide a pathway for organisms to respond to local environmental conditions by influencing gene expression. However, we still know little about the spatial distribution of epigenetic variation in natural systems, how it relates to the distribution of genetic variation and the environmental structure of the landscape, and the processes that generate and maintain it. Studies examining spatial patterns of genetic and epigenetic variation can provide valuable insights into how ecological and population...

Supplementary information for: Deterministic assembly of arrays of lithographically defined WS_2 and MoS_2 monolayer features directly from multilayer sources into van der Waals heterostructures

Hayden Taylor, Vu Nguyen, Hannah Gramling, Clarissa Towle, Wan Li, Der-Hsien Lien, Hyungjin Kim, Daryl Chrzan, Ali Javey, Ke Xu & Joel Ager
One of the major challenges in the van der Waals (vdW) integration of 2D materials is achieving high-yield and high-throughput assembly of pre-defined sequences of monolayers into heterostructure arrays. Mechanical exfoliation has recently been studied as a promising technique to transfer monolayers from a multilayer source synthesized by other techniques, allowing the deposition of a wide variety of 2D materials without exposing the target substrate to harsh synthesis conditions. Although a variety of processes have...
