David LeBauer, Burnette Maxwell, Jeffrey Demieville, Noah Fahlgren, Andrew French, Roman Garnett, Zhenbin Hu, Kimberly Huynh, Rob Kooper, Zongyang Li, Maitiniyazi Maimaitijiang, Jerome Mao, Todd Mockler, Geoffrey Morris, Maria Newcomb, Michael Ottman, Philip Ozersky, Sidike Paheding, Duke Pauli, Robert Pless, Wei Qin, Kristina Riemer, Gareth Rohde, William Rooney, Vasit Sagan … & Charles Zender
The ARPA-E funded TERRA-REF project is generating open-access reference datasets for the study of plant sensing, genomics, and phenomics. Sensor data were generated by a field scanner sensing platform that captures color, thermal, hyperspectral, and active flourescence imagery as well as three dimensional structure and associated environmental measurements. This dataset is provided alongside data collected using traditional field methods in order to support calibration and validation of algorithms used to extract plot level phenotypes from...

R code for Snyder, Ellner, and Hooker, \"Time and chance: using age partitioning to understand how luck drives variation in reproductive success\"

Robin Snyder, Stephen Ellner & Giles Hooker
Over the course of individual lifetimes, luck usually explains a large fraction of the between- individual variation in lifespan or lifetime reproductive output (LRO) within a population, while variation in individual traits or “quality” explains much less. To understand how, where in the life cycle, and through which demographic processes luck trumps trait variation, we show how to partition by age the contributions of luck and trait variation to LRO variance, and how to quantify...

SARS-CoV-2 transmission and control in a hospital setting: an individual-based modelling study

Qimin Huang, Anirban Mondal, Xiaobing Jiang, Mary Ann Horn, Fei Fan, Peng Fu, Xuan Wang, Hongyang Zhao, Martial Ndeffo Mbah & David Gurarie
Background: Development of strategies for mitigating the severity of COVID-19 is now a top public health priority. We sought to assess strategies for mitigating the COVID-19 outbreak in a hospital setting via the use of non-pharmaceutical interventions. Methods: We developed an individual-based model for COVID-19 transmission in a hospital setting. We calibrated the model using data of a COVID-19 outbreak in a hospital unit in Wuhan. The calibrated model was used to simulate different intervention...

Depot-specific analysis of human adipose cells and their responses to Bisphenol S

Ella Atlas, Vian Peshdary, George Styles, Rémi Gagné, Carole Yauk & Alexander Sorisky
Exposure to endocrine disrupting chemicals (EDCs) is associated with adverse health outcomes including obesity and diabetes. Obesity, and more specifically visceral obesity, is correlated with metabolic disease. The adipose tissue is an endocrine organ and a potential target for many environmental pollutants including bisphenols. The subcutaneous and the omental (visceral) depots are comprised of mature adipocytes and residing progenitors, which may be different between the depots and may be EDCs targets. Bisphenol A (BPA) is...

Data from: Postglacial recolonization of North America by spadefoot toads: integrating niche and corridor modeling to study species’ range dynamics over geologic time

Iulian Gherghel & Ryan Andrew Martin
Understanding the factors that shape species’ distributions is a key topic in biogeography. As climates change, species can either cope with these changes through evolution, plasticity or by shifting their ranges to track the optimal climatic conditions. Ecological niche modeling (ENM) is a widespread technique in biogeography that estimates the niche of the organism by using occurrences and environmental data to estimate species’ potential distributions. ENMs are often criticized for failing to take species’ dispersal...

Data from: Evidence for the evolution of thermal tolerance but not desiccation tolerance in response to hotter, drier city conditions in a cosmopolitan, terrestrial isopod

Aaron Richard Yilmaz, Sarah Diamond & Ryan Martin
Cities are often hotter and drier compared with nearby undeveloped areas, but how organisms respond to these multifarious stressors associated with urban heat islands is largely unknown. Terrestrial isopods are especially susceptible to temperature and aridity stress as they have retained highly permeable gills from their aquatic ancestors. We performed a two‐temperature common garden experiment with urban and rural populations of the terrestrial isopod, Oniscus asellus , to uncover evidence for plastic and evolutionary responses...

Data from: Carryover effects and the evolution of polyphenism

David Pfennig, Sofia De La Serna Buzón & Ryan Martin
An individual’s early-life environment and phenotype often influence its traits and performance as an adult. We investigated whether such ‘carryover effects’ are associated with alternative, environmentally induced phenotypes (‘polyphenism’), and, if so, whether they influence polyphenism’s evolution. To do so, we studied spadefoot toads, Spea multiplicata, which have evolved a polyphenism consisting of two, dramatically different forms: a carnivore morph and an omnivore morph. We sampled both morphs from a fast-drying and a slow-drying pond...

Thermal tolerance of Lasius americanus across urbanization and geographical gradients

Sarah Diamond
Cities are emerging as a new venue to overcome the challenges of obtaining data on compensatory responses to climatic warming through phenotypic plasticity and evolutionary change. In this review, we highlight how cities can be used to explore physiological trait responses to experimental warming and also how cities can be used as human-made space-for-time substitutions. We synthesized the current literature and found evidence for significant plasticity and evolution in thermal tolerance trait responses to urban...

Weighted haltere and imposed haltere stroke reduction tethered flying Drosophila kinematics

Michael Rauscher & Jessica Fox
In the true flies (Diptera) the hind wings have evolved into specialized mechanosensory organs known as halteres, which are sensitive to gyroscopic and other inertial forces. Together with the fly’s visual system, the halteres direct head and wing movements through a suite of equilibrium reflexes that are crucial to the fly’s ability to maintain stable flight. As in other animals (including humans), this presents challenges to the nervous system as equilibrium reflexes driven by the...

Urban / rural acorn ant metabolic rate and running speed

Sarah E. Diamond
Metabolic rates of ectotherms are expected to increase with global trends of climatic warming. But the potential for rapid, compensatory evolution of lower metabolic rate in response to rising temperatures is only starting to be explored. Here, we explored rapid evolution of metabolic rate and locomotor performance in acorn-dwelling ants (Temnothorax curvispinosus) in response to urban heat island effects. We reared ant colonies within a laboratory common garden (25 °C) to generate a lab-born cohort...

Diagnosis of prion diseases by RT-QuIC results in improved surveillance

Brian Appleby
Objective: We present the National Prion Disease Pathology Surveillance Center’s (NPDPSC) experience using cerebrospinal fluid (CSF) real time quaking induced conversion (RT-QuIC) as a diagnostic test, examine factors associated with false negative RT-QuIC results, and investigate RT-QuIC’s impact on prion disease surveillance. Methods: Between May 2015-April 2018, the NPDPSC received 10,498 CSF specimens that were included in the study. Sensitivity and specificity analyses were performed using 567 autopsy verified cases. Prion disease type, demographic characteristics,...

Data from: Takeoff diversity in Diptera

Alexandra M. Yarger, Katherine Jordan, Jessica Fox & Alexa Smith
The order Diptera (true flies) are named for their two wings because their hindwings have evolved into specialized mechanosensory organs called halteres. Flies use halteres to detect body rotations and maintain stability during flight and other behaviors. The most recently diverged dipteran monophyletic subsection, the Calyptratae, is highly successful, accounting for ~12% of dipteran diversity and includes common families like house flies. These flies move their halteres independently from their wings and oscillate their halteres...
