Elizabeth W. McCarthy, Jacob B. Landis, Amelda Kurti, Amber J. Lawhorn, Mark W. Chase, Sandra Knapp, Steven C. Le Comber, Andrew R. Leitch & Amy Litt
Background: Polyploidy has played a major role in angiosperm evolution. Previous studies have examined polyploid phenotypes in comparison to their extant progenitors, but not in context of predicted progenitor phenotypes at allopolyploid origin. In addition, differences in the trends of polyploid versus diploid evolution have not been investigated. We use ancestral character-state reconstructions to estimate progenitor phenotype at allopolyploid origin to determine patterns of polyploid evolution leading to morphology of the extant species. We also...

Data from: Cascading effects of mammalian herbivores on ground-dwelling arthropods: variable responses across arthropod groups, habitats and years

Eric M. Cecil, Marko J. Spasojevic & J. Hall Cushman
1. Large mammalian herbivores are well known to shape the structure and function of ecosystems worldwide and these effects can in turn cascade through systems to indirectly influence other animal species. A wealth of studies have explored the effects of large mammals on arthropods, but to date they have reported such widely varying results that generalizations have been elusive. Three factors are likely drivers of this variability: the widely varying life-history characteristics of different arthropod...

Identifications to genus or higher taxonomic ranks were omitted. All non-marine fossil groups (e.g., plants, vertebrates, pollen,...

Conflicting signal in transcriptomic markers leads to a poorly resolved backbone phylogeny of Chalcidoid wasps

Junxia Zhang, Amelia R.I. Lindsey, Ralph S. Peters, John M. Heraty, Keith R. Hopper, John H. Werren, Ellen O. Martinson, James B. Woolley, Matt J. Yoder & Lars Krogmann
Chalcidoidea (Hymenoptera) are a megadiverse superfamily of wasps with astounding variation in both morphology and biology. Most species are parasitoids and important natural enemies of insects in terrestrial ecosystems. In this study, we explored a transcriptome-based phylogeny of Chalcidoidea and found that poorly resolved relationships could only be marginally improved by adding more genes (a total of 5,591) and taxa (a total of 65), proof-checking for errors of homology and contamination, and decreasing missing data....

Context: Previous studies have shown that the endocannabinoid system plays a major role in energy metabolism through the actions of its main mediators, 2-arachidonoyl-sn-glycerol (2-AG) and anandamide (AEA). Objective: We examined serum levels of major endocannabinoid mediators and their association with clinical parameters in patients with end-stage renal disease (ESRD). Design and Setting: Serum concentrations of 2-AG and AEA were measured in patients on maintenance hemodialysis (MHD), and correlations with various clinical and laboratory indices...

Data from: Evolutionary potential of thermal preference and heat tolerance in Drosophila subobscura

Luis E. Castañeda, Valèria Romero-Soriano, Andres Mesas, Derek A. Roff & Mauro Santos
Evolutionary change of thermal traits (i.e. heat tolerance and behavioral thermoregulation) is one of the most important mechanisms exhibited by organisms to respond to global warming. However, the evolutionary potential of heat tolerance, estimated as narrow-sense heritability, depends on the methodology employed. An alternative adaptive mechanism to buffer extreme temperatures is behavioral thermoregulation, although the association between heat tolerance and thermal preference is not clearly understood. We suspect that methodological effects associated with the duration...

John M. Martinis, Sergio Boixo, Hartmut Neven, Frank Arute, Kunal Arya, Ryan Babbush, Dave Bacon, Joseph C. Bardin, Rami Barends, Rupak Biswas, Fernando G. S. L. Brandao, David A. Buell, Brian Burkett, Yu Chen, Zijun Chen, Ben Chiaro, Roberto Collins, William Courtney, Andrew Dunsworth, Edward Farhi, Brooks Foxen, Austin Fowler, Craig Gidney, Marissa Giustina, Rob Graff … & Adam Zalcman
The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here, we report using a processor with programmable superconducting qubits to create quantum states on 53 qubits, corresponding to a computational state-space of dimension 2^53 ∼ 10^16. Measurements from repeated...

Data from: Gender diversity of editorial boards and gender differences in the peer review process at six journals of ecology and evolution.

Charles Fox, Meghan Duffy, Daphne Fairbairn & Jennifer Meyer
Despite substantial progress for women in science, women remain underrepresented in many aspects of the scholarly publication process. We examined how the gender diversity of editors and reviewers changed over time for six journals in ecology and evolution (2003-2015 for four journals, 2007-2015 or 2009-2015 for the other two), and how several aspects of the peer review process differed between female and male editors and reviewers. We found that, for five of the six journals,...

PTV VISSIM simulation data for efficient eco-ramp control project funded by NCST 18-19

Guoyuan Wu & Zhouqiao Zhao
Our current transportation system faces a variety of issues in terms of safety, mobility, and environmental sustainability. The emergence of innovative intelligent transportation system (ITS) technologies such as connected and automated vehicles (CAVs) and transportation electrification unfold unprecedented opportunities to address aforementioned issues. In this project, we propose a hierarchical ramp control system that not only allows microscopic cooperative maneuvers for connected and automated electric vehicles (CAEVs) on the ramp to merge into mainline traffic...

Wide spectrum and high frequency of genomic structural variation, including transposable elements, in large double stranded DNA viruses

Clement Gilbert, Elisabeth Herniou, Yannis Moreau, Nicolas Lévêque, Carine Meignin, Laurent Daeffler, Brian Federici, Richard Cordaux & Vincent Loiseau
Our knowledge of the diversity and frequency of genomic structural variation segregating in populations of large double stranded (ds) DNA viruses is limited. Here we sequenced the genome of a baculovirus (AcMNPV) purified from beet armyworm (Spodoptera exigua) larvae at depths >195,000X using both short-read (Illumina) and long-read (PacBio) technologies. Using a pipeline relying on hierarchical clustering of structural variants (SVs) detected in individual short- and long-reads by six variant callers, we identified a total...

Data from: Interspecific conflict and the evolution of ineffective rhizobia

Kelsey A. Gano-Cohen, Camille E. Wendlandt, Peter J. Stokes, Mia A. Blanton, Kenjiro W. Quides, Avissa Zomorrodian, Eunice S. Adinata & Joel L. Sachs
Microbial symbionts exhibit broad genotypic variation in their fitness effects on hosts, leaving hosts vulnerable to costly partnerships. Interspecific conflict and partner‐maladaptation are frameworks to explain this variation, with different implications for mutualism stability. We investigated the mutualist service of nitrogen fixation in a metapopulation of root‐nodule forming Bradyrhizobium symbionts in Acmispon hosts. We uncovered Bradyrhizobium genotypes that provide negligible mutualist services to hosts and had superior in planta fitness during clonal infections, consistent with...

Data from: Combined effects of mutualistic rhizobacteria counteract virus-induced suppression of indirect plant defenses in soybean

Hannier Pullido, Kerry E. Mauck, Consuelo M. De Moraes & Mark C. Mescher
It is increasingly clear that microbial plant symbionts can influence interactions between their plant hosts and other organisms. Yet, such effects remain poorly understood, particularly under ecologically realistic conditions where plants simultaneously interact with diverse mutualists and antagonists. Here we examine how the effects of a plant virus on indirect plant defenses against its insect vector are influenced by co-occurrence of other microbial plant symbionts. Using a multi-factorial design, we manipulated colonization of soybean using...

Data from: Cost-efficient high throughput capture of museum arthropod specimen DNA using PCR-generated baits

Alexander Knyshov, Eric R. L. Gordon & Christiane Weirauch
Gathering genetic data for rare species is one of the biggest remaining obstacles in modern phylogenetics, particularly for megadiverse groups such as arthropods. Next generation sequencing techniques allow for sequencing of short DNA fragments contained in preserved specimens >20 years old, but approaches such as whole genome sequencing are often too expensive for projects including many taxa. Several methods of reduced representation sequencing have been proposed that lower the cost of sequencing per specimen, but...

Influence of Climate and Human Preferences on Patterns of Taxonomic and Functional Biodiversity of Recreational Parks

Peter Ibsen, Dorothy Borowy, Mia Rochford, Christopher Swan & G Darrel Jenerette
Recreational urban parks support diverse assemblages of plants that contribute ecosystem services to billions of individuals in cities throughout the world. Drivers of ecosystem services in parks are complex, as climate and human preferences interact with multiple species of vegetation types. Yet, informal observations suggest that recreational parks are built consistently to a specific typology. Here we ask: what are the patterns of ecosystem services and vegetation biodiversity in cities of varying climate in the...

Speed trajectory data from adaptive eco-driving applications

Peng Hao, Zhensong Wei & Matthew Barth
The eco-approach and departure (EAD) application for signalized intersections has been proved to be environmentally efficient in a Connected and Automated Vehicles (CAVs) system. In the real-world traffic, the traffic-related information received from sensing or communication devices is highly uncertain due to the limited sensing range and varying driving behaviors of other vehicles. This uncertainty increases the difficulty to predict the actual queue length of the downstream intersection. It further brings great challenge to derive...
