Data from: Consistently positive effect of species diversity on ecosystem, but not population, temporal stability

Qianna Xu
Despite much recent progress, our understanding of diversity-stability relationships across different study systems remains incomplete. In particular, recent theory clarified that within-species population stability and among-species asynchronous population dynamics combine to determine ecosystem temporal stability, but their relative importance in modulating diversity-ecosystem temporal stability relationships in different ecosystems remains unclear. We addressed this issue with a meta-analysis of empirical studies of ecosystem and population temporal stability in relation to species diversity across a range of...

Breaking a species barrier by enabling hybrid recombination

G. Ozan Bozdag, Jasmine Ono, Jai A. Denton, Emre Karakoc, Neil Hunter, Jun-Yi Leu & Duncan Greig
Hybrid sterility maintains reproductive isolation between species by preventing them from exchanging genetic material. Anti-recombination can contribute to hybrid sterility when different species’ chromosome sequences are too diverged to cross-over efficiently during hybrid meiosis, resulting in chromosome mis-segregation and aneuploidy. The genome sequences of the yeasts Saccharomyces cerevisiae and Saccharomyces paradoxus have diverged by about 12% and their hybrids are sexually sterile: nearly all of their gametes are aneuploid and inviable. Previous methods to increase...

Data from: Diverse and complex muscle spindle afferent firing properties emerge from multiscale muscle mechanics

Kyle Blum, Brian Horslen, Kenneth Campbell, Brian Horslen, Paul Nardelli, Stephen Housley, Timothy Cope & Lena Ting
Despite decades of research, we lack a mechanistic framework capable of predicting how movement-related signals are transformed into the diversity of muscle spindle afferent firing patterns observed experimentally, particularly in naturalistic behaviors. Here, a biophysical model demonstrates that well-known firing characteristics of mammalian muscle spindle Ia afferents – including movement history dependence, and nonlinear scaling with muscle stretch velocity – emerge from first principles of muscle contractile mechanics. Further, mechanical interactions of the muscle spindle...

Heterogenous susceptibility to R-pyocins in populations of Pseudomonas aeruginosa sourced from cystic fibrosis lungs

Madeline Mei, Jacob Thomas & Stephen Diggle
Bacteriocins are proteinaceous antimicrobials produced by bacteria which are active against other strains of the same species. R-type pyocins are phage tail-like bacteriocins produced by Pseudomonas aeruginosa. Due to their anti-pseudomonal activity, R-pyocins have potential as therapeutics in infection. P. aeruginosa is a Gram-negative opportunistic pathogen and is particularly problematic for individuals with cystic fibrosis (CF). P. aeruginosa from CF lung infections develop increasing resistance to antibiotics, making new treatment approaches essential. P. aeruginosa populations...

This is a two-year National Leadership Grant for Libraries Demonstration Project to facilitate a multi-university study of faculty data management plans (DMPs). The primary outputs of this project will be an analytic rubric to standardize the review of data management plans as a means to inform targeted expansion or development of research data services at academic libraries; and a study utilizing the rubric that presents the results of data management plan analyses at five universities....

Conspiratorial thinking and political ideology

David Illingworth, Rick Thomas & Sara Volk
Conspiratorial thinking is a growing, yet controversial area of psychological science. Prior research suggests that fear may be a motivating factor in conspiratorial ideation (Tetlock, 2002; Boat & Prunier, 2013; Goertzel, 1994), but that this tendency is more closely correlated with belief in conservative political values rather than liberal values. We suspected that this reported discrepancy may be attributed to existent methodology for detecting conspiratorial thinking which may be better calibrated to issues that are...

Data from: How do morphological sharpness measures relate to puncture performance in viperid snake fangs?

Stephanie B. Crofts, Yang Lai, Yuhang Hu & Philip S.L. Anderson
It makes intuitive sense that you need a sharp tool to puncture through a tough material. The typical approach to evaluating sharpness in biological puncturing tools is to treat morphological measurements as a proxy for puncture ability. However there are multiple approaches to measuring sharpness, and the relative influence of morphology on function remains unclear. Our goal is to determine what aspects of tip morphology have the greatest impact on puncture ability, using a) viper...

Genotypes at 10 microsatellite loci for 8 perennial, polygyne colonies of Vespula squamosa

Carl Dyson
Many highly social species show plasticity in their social structure in response to different environmental conditions. For example, typical colonies of the yellowjacket wasp Vespula squamosa are headed by a single reproductive queen and survive for only a single season. However, in warmer climates, V. squamosa colonies sometimes persist for multiple years and can grow to extremely large size. We used genetic markers to understand patterns of reproduction and recruitment within these perennial colonies. We...

Adaptive shifts underlie the divergence in wing morphology in bombycoid moths

Brett Aiello, Milton Tan, Usama Bin Sikandar, Alexis Alvey, Burhanuddin Bhinderwala, Katalina Kimball, Jesse Barber, Chris Hamilton, Akito Kawahara & Simon Sponberg
The evolution of flapping flight is linked to the prolific success of insects. Across Insecta, wing morphology diversified, strongly impacting aerodynamic performance. In the presence of ecological opportunity, discrete adaptive shifts and early bursts are two processes hypothesized to give rise to exceptional morphological diversification. Here, we use the diverse sister-families Sphingidae and Saturniidae to answer how the evolution of aerodynamically important traits is linked to clade divergence and through what process(es) these traits evolve....

Dataset from: Warming effects on grassland productivity depend on plant diversity

Junjiong Shao, Xuhui Zhou, Kees Van Groenigen, Guiyao Zhou, Huimin Zhou, Lingyan Zhou, Meng Lu, Jianyang Xia, Lin Jiang, Bruce Hungate, Yiqi Luo, Fangliang He & Madhav Thakur
Aim: Climate warming and biodiversity loss both alter plant productivity, yet we lack an understanding of how biodiversity regulates the responses of ecosystems to warming. In this study, we examine how plant diversity regulates the responses of grassland productivity to experimental warming using meta-analytic techniques. Location: Global Major taxa studied: Grassland ecosystems Methods: Our meta-analysis is based on warming responses of 40 different plant communities obtained from 20 independent studies on grasslands across five continents....

FRET imaging and curvature data of freely moving C. elegans

Daniel Porto
The force - induced unfolding and refolding of proteins is speculated to be a key mechanism in the sensing and transduction of mechanical signals in the living cell. Yet, little evidence has been gathered for its existence in vivo . Prominently, s tretch - induced unfolding is postulated to be the activation mechanism of the t witchin/titin family of autoinhibited sarcomeric kinases linked to the mechanical stress response of muscle. To test the occurrence of...

Time-series drinking water metagenomes: Assemblies & MAGs

Solize Vosloo, Linxuan Huo, Christopher Anderson, Maria Sevillano & Ameet Pinto
Reconstructing microbial genomes from metagenomic short-read data can be challenging due to the unknown and uneven complexity of microbial communities. This complexity encompasses highly diverse populations which often includes strain variants. Reconstructing high-quality genomes is a crucial part of the metagenomic workflow as subsequent ecological and metabolic inferences depend on their accuracy, quality and completeness. In contrast to microbial communities in other ecosystems, there has been no systematic assessment of genome-centric metagenomic workflows for drinking...

Warming effect on ecosystem stability

Quan Quan, Fangyue Zhang, Lin Jiang, Han Y. H. Chen, Jinsong Wang, Fangfang Ma, Bing Song & Shuli Niu
1. Ecosystem stability is essential to its sustainable functions and services to humanity. Although climate warming is projected to vary from 1-5ºC by the end of 21st century, how the temporal stability of plant community biomass production responds to different warming scenarios remains unclear. 2. To fill this knowledge gap, we conducted a 6-year field experiment with three levels of warming treatments (control, + 1.5oC, + 5oC) by using infrared radiators, in an alpine meadow...

Island biogeography of soil bacteria and fungi: similar patterns, but different mechanisms

Shaopeng Li, Pandeng Wang, Yongjian Chen, Maxwell Wilson, Xian Yang, Chao Ma, Jianbo Lu, Xiao-Yong Chen, Jianguo Wu, Wen-Sheng Shu & Lin Jiang
Microbes, similar to plants and animals, exhibit biogeographic patterns. However, in contrast with the considerable knowledge on the island biogeography of higher organisms, we know little about the distribution of microorganisms within and among islands. Here, we explored insular soil bacterial and fungal biogeography and underlying mechanisms, using soil microbiota from a group of land-bridge islands as a model system. Similar to island species-area relationships observed for many macroorganisms, both island-scale bacterial and fungal diversity...
