EAR-Climate: Effects of nutrient pollution, temperature, discharge, urbanization, and groundwater inputs on CO2 and CH4 emissions from streams

John Ayers
We propose to measure daily and seasonal variations in stream chemistry and gas emissions across a gradient of nutrient pollution levels, discharge, and urban development in three streams in middle TN. We will test the following hypotheses: 1) emissions of CO2 are decreased and CH4 increased by nutrient pollution; 2) emissions of CO2 increase and CH4 increase faster with temperature; 3) gas emissions decrease with increased discharge/precipitation; 4) urbanization increases CO2 and CH4 emissions; and...

Data from: Laminar microcircuitry of visual cortex producing attention-associated electric fields

Jacob Westerberg, Michelle Schall, Alexander Maier, Geoffrey Woodman & Jeffrey Schall
Cognitive operations are widely studied by measuring electric fields through EEG and ECoG. However, despite their widespread use, the component neural circuitry giving rise to these signals remains unknown. Specifically, the functional architecture of cortical columns which results in attention-associated electric fields has not been explored. Here we detail the laminar cortical circuitry underlying an attention-associated electric field often measured over posterior regions of the brain in humans and monkeys. First, we identified visual cortical...

The life and times of Pteridinium simplex

Simon Darroch, Brandt Gibson, Maggie Syversen, Imran Rahman, Rachel Racicot, Frances Dunn, Susana Gutarra-Diaz, Eberhard Schindler, Achim Wehrmann & Marc Laflamme
Pteridinium simplex is an iconic erniettomorph taxon best known from late Ediacaran successions in South Australia, Russia, and Namibia. Despite nearly 100 years of study, there remain fundamental questions surrounding the paleobiology and -ecology of this organism, including it’s life position relative the sediment-water interface, and how it fed and functioned within benthic communities. Here, we combine a re-description of specimens housed at the Senckenberg Forschungsinstitut und Naturmuseum Frankfurt with field observations of fossiliferous surfaces...

Toward Linguistic Responsibility

Emanuele Costa
In this short article, I analyze forms of public speech by individuals in positions of power through a framework based on Austin’s theory of speech acts. I argue that because of the illocutionary and perlocutionary force attached to such individuals’ offices and their public figures, their public speech qualifies for being framed as speech acts—which are not covered by even a broad understanding of freedom of speech or right to privacy. Therefore, I formulate a...

Combining metabolomics and experimental evolution reveals key mechanisms underlying longevity differences in laboratory evolved Drosophila melanogaster populations

Mark Phillips, Kenneth R. Arnold, Zer Vue, Heather K. Beasley, Edgar Garza-Lopez, Andrea G. Marshall, Derrick J. Morton, Melanie R. McReynolds, Thomas T. Barter & Antentor Hinton
Experimental evolution with Drosophila melanogaster has been used extensively for decades to study aging and longevity. In recent years, the addition of DNA and RNA sequencing to this framework has allowed researchers to leverage the statistical power inherent to experimental evolution to study the genetic basis of longevity itself. Here, we incorporated metabolomic data into to this framework to generate even deeper insights into the physiological and genetic mechanisms underlying longevity differences in three groups...

Seasonality of host immunity in a tropical disease system

Jamie Voyles, Goncalo Rosa, Rachel Perez, Lora Richards, Corinne Richards-Zawacki, Angela Smilanich, Laura K. Reinert, Louise A. Rollins-Smith, Daniel Wetzel & Jamie Voyles
Infectious disease systems frequently exhibit strong seasonal patterns, yet the mechanisms that underpin intra-annual cycles are unclear, particularly in tropical regions. We hypothesized that host immune function fluctuates seasonally, contributing to oscillations in infection patterns in a tropical disease system. To test this hypothesis, we investigated a key host defense of amphibians against a lethal fungal pathogen, Batrachochytrium dendrobatidis (Bd). We integrated two field experiments in which we perturbed amphibian skin secretions, a critical host...
