Species responses to changing precipitation depends on trait plasticity rather than trait means and intraspecific variationBingwei Zhang, Yann Hautier, Xingru Tan, Cuihai You, Marc Cadotte, Chengjin Chu, Lin Jiang, Xinghua Sui, Tingting Ren, Xingguo Han & Shiping Chen
1. Trait-based approaches are key to develop mechanistic understanding of differences in plant species performance under environmental change. While mean trait values have been widely used to link functional traits to species performance, the contribution of intraspecific trait variation and trait plasticity remains unclear. Moreover, environmentally induced changes in species biomass is caused by changes in the number of individuals and individual growth rate, both of which should be influenced by trait differences and plasticity....
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: Synergistic effects of nitrogen and CO2 enrichment on alpine grassland biomass and community structureJuntao Zhu, Yangjian Zhang, Xian Yang, Ning Chen & Lin Jiang
Global environmental change is altering Earth’s ecosystems. However, much research has focused on ecosystem-level responses, and we know substantially less about community-level responses to global change stressors. Here we conducted a 6-year field experiment in a high-altitude (4600 m above sea level) alpine grassland on the Tibetan Plateau to explore the effects of nitrogen (N) addition and rising atmospheric CO2 concentration on plant communities. Our results showed that N and CO2 enrichment had synergistic effects...
Data from: Diverse and complex muscle spindle afferent firing properties emerge from multiscale muscle mechanicsKyle 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...
Data from: Consistently positive effect of species diversity on ecosystem, but not population, temporal stabilityQianna 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...

Heterogenous susceptibility to R-pyocins in populations of Pseudomonas aeruginosa sourced from cystic fibrosis lungsMadeline 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...
With climate models projecting increasing frequency and severity of heat waves, heat-related illness (HRI) due to environmental exposure is of increasing public health concern. Agricultural workers are particularly vulnerable to HRI. HRI covers a spectrum of symptoms, ranging in severity from sweating to heat stroke or, perhaps, death. Despite recent scientific advances, the processes underlying HRI are not well understood, and health inequities persist among agricultural workers. Heat is the initiating factor in HRI, but...
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...
In many insects, wing movements are generated indirectly via exoskeletal deformations. Measurements of inertial and aerodynamic power suggest that elastic recovery of energy between wingstrokes might reduce power requirements of flight. We tested three questions. 1) Can the thorax itself provide significant energy return? 2) Does a simple damped elastic model describe the bulk mechanical behavior? and 3) Are different regions of the thorax specialized for elastic energy exchange? We measured deformation mechanics of the...
