Functional gene analyses (qPCR) were conducted at Colorado School of Mines for samples of the...

Perceptual restoration fails to recover unconscious processing for smooth eye movements after occipital stroke

Sunwoo Kwon, Jude Mitchell & Krystel Huxlin
Visual pathways that guide actions do not necessarily mediate conscious perception. Patients with primary visual cortex (V1) damage lose conscious perception but often retain unconscious abilities (e.g. blindsight). Here, we asked if saccade accuracy and post-saccadic following responses (PFRs) that automatically track target motion upon saccade landing are retained when conscious perception is lost. We contrasted these behaviors in the blind and intact fields of 8 chronic V1-stroke patients, and in 8 visually-intact controls. Saccade...

Ultrafast two-photon fluorescence imaging of cerebral blood circulation in the mouse brain in vivo

Guanghan Meng
Characterizing blood flow dynamics in vivo is critical to understand the function of vascular network under physiological and pathological conditions. Existing methods for hemodynamic imaging have insufficient spatial and temporal resolution to monitor blood flow at cellular level in large blood vessels. By employing an ultrafast line-scanning module based on free-space angular chirped enhanced delay (FACED), we achieved two-photon fluorescence imaging of cortical blood flow at 1,000 2D frames and 1,000,000 1D line scans per...

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...

Dietary ethanol ingestion by free-ranging spider monkeys (Ateles geoffroyi)

Christina Campbell, Aleksey Maro, Victoria Weaver & Robert Dudley
Ethanol within ripe and over-ripe fruit is produced naturally through the metabolic activity of fermentative yeasts. As a consequence, frugivorous animals may chronically consume ethanol as part of their routine diet, although direct measurements of such exposure are lacking. Here, we present data on ethanol concentrations within fruits of the Neotropical tree Spondias mombin (Anacardiaceae) that are eaten by Geoffroy's spider monkeys (Ateles geoffroyi) on Barro Colorado Island, Panama. Of collected fruits that were partially...

Fossilized pollen malformations as indicators of past environmental stress and meiotic disruption: insights from modern conifers

Jeffrey Benca, Ivo Duijnstee & Cindy Looy
Pollen malformations have been proposed as a paleoenvironmental stress proxy. However, the frequency and variability of pollen malformations under near-optimal conditions and environmental stress, as well as their developmental origins, remain unclear. To bridge these gaps, we compared pollen malformation frequencies and assemblages of 14 extant conifer genera of Pinaceae and Podocarpaceae producing saccate (winged) grains grown under near-optimal conditions. These baseline pollen yields were compared with those produced by Pinus mugo ‘Columnaris’ cultured under...

Joint effects of genes underlying a temperature specialization tradeoff in yeast

Faisal AlZaben, Rachel Brem, Julie Chuong & Melanie Abrams
A central goal of evolutionary genetics is to understand, at the molecular level, how organisms adapt to their environments. For a given trait, the answer often involves the acquisition of variants at unlinked sites across the genome. Genomic methods have achieved landmark successes in pinpointing adaptive loci. To figure out how a suite of adaptive alleles work together, and to what extent they can reconstitute the phenotype of interest, requires their transfer into an exogenous...

Parental population range expansion before secondary contact promotes heterosis

Ailene MacPherson, Silu Wang, Ryo Yamaguchi, Loren Rieseberg & Sarah Otto
Population genomic analysis of hybrid zones is instrumental to our understanding of the evolution of reproductive isolation. Many temperate hybrid zones are formed by the secondary contact between two parental populations that have undergone post-glacial range expansion. Here we show that explicitly accounting for historical parental isolation followed by range expansion prior to secondary contact is fundamental for explaining genetic and fitness patterns in these hybrid zones. Specifically, ancestral population expansion can result in allele...

Phenotypic and genomic diversification with isolation by environment along elevational gradients in a neotropical treefrog

Ricardo Medina, Ella Vázquez-Domínguez, Guinevere O.U. Wogan, Ke Bi, Flavia Termignoni-García, Manuel Hernando Bernal, Juan P. Jaramillo-Correa & Ian J. Wang
Understanding how geographic and environmental heterogeneity drive local patterns of genetic variation is a major goal of ecological genomics and a key question in evolutionary biology. The tropical Andes and inter-Andean valleys are shaped by markedly heterogeneous landscapes, where species experience strong selective processes. We examined genome-wide SNP data together with behavioral and ecological traits (mating calls and body size) known to contribute to genetic isolation in anurans in the emerald-eyed treefrog, Boana platanera, distributed...

Supporting data for: Estimate of OH trends over one decade in North American cities

Qindan Zhu, Josh Laughner & Ron Cohen
The hydroxyl radical (OH) is the most important oxidant on global and local scales in the troposphere. Urban OH controls the removal rate of primary pollutants and triggers the production of ozone. Interannual trends of OH in urban areas are not well documented or understood due to the short lifetime and high spatial heterogeneity of OH. We utilize machine learning with observational inputs emphasizing satellite remote sensing observations to predict surface OH in 49 North...

Risk factors for third-generation cephalosporin-resistant and extended-spectrum β-lactamase-producing Escherichia coli carriage in domestic animals of semirural parishes east of Quito, Ecuador

Siena Mitman
Extended-spectrum β-lactamase (ESBL)-producing and other antimicrobial resistant (AR) Escherichia coli threaten human and animal health worldwide. This study examined risk factors for domestic animal colonization with ceftriaxone-resistant (CR) and ESBL-producing E. coli in semirural parishes east of Quito, Ecuador, where small-scale food animal production is common. Survey data regarding household characteristics, animal care, and antimicrobial use were collected from 304 households over three sampling cycles, and 1195 environmental animal fecal samples were assessed for E....

Phylogeny of species, infraspecific taxa, and forms in subgenus Xiphium (Iris: Iridaceae) that have centers of diversity in the Mediterranean Basin biodiversity hotspot

Carol Wilson, Zoe Boosalis, Michael Sandor, Manuel Crespo & Mario Martinez-Azorin
Iris subgenus Xiphium is a small group of taxa that mostly occur in the Mediterranean Basin, a long-recognized biodiversity hotspot. Phylogenetic relationships among these Iris were reconstructed based on sequence data from 110 nuclear markers and whole plastomes using Bayesian inference and maximum likelihood methods. Best trees based on plastome and combined datasets resolved subgenus Xiphium and I. xiphium as not monophyletic while nuclear data resolved the subgenus as monophyletic but I. xiphium as not...

Sofia Medina Ruiz, Caroline Albertin, Therese Mitros, Hannah Schmidbaur, Gustavo Sanchez, Z.Y. Wang, Jane Grimwood, Joshua Rosenthal, Clifton Ragsdale, Oleg Simakov & Daniel Rokhsar
Cephalopods are known for their large nervous systems, complex behaviors and morphological innovations. To investigate the genomic underpinnings of these features, we assembled the chromosomes of the Boston market squid Doryteuthis (Loligo) pealeii and the California two-spot octopus, Octopus bimaculoides, and compared them with those of the Hawaiian bobtail squid, Euprymna scolopes. The genomes of the soft-bodied (coleoid) cephalopods are highly rearranged relative to other extant molluscs, indicating an intense, early burst of genome restructuring....
