Ant exclusion decomposition data

Anna Cates
Ants play multiple roles in ecosystems, but their ability to affect decomposition processes in temperate grasslands is relatively unknown. We investigated whether the suppression of ant populations influenced litter decomposition in grasslands via predation of some decomposers (e.g., mites and springtails) and/or microbial activity and composition. We performed two successful ant suppression treatments (seven weeks, 37% suppression, year 1, 10 weeks, 70% suppression, year 2) over the course of a 59-week experiment. We then assayed...

Assessing mammal species richness and occupancy in a Northeast Asian temperate forest shared by cattle

Jiawei Feng, Yifei Sun, Hailong Li, Yuqi Xiao, Dandan Zhang, James Smith, Jianping Ge & Tianming Wang
Aim: Asian forests are becoming increasingly degraded and fragmented by the extensive intensification of anthropogenic activities; these activities threaten wildlife and ecosystem sustainability. Facing a defaunation crisis, managers need more information on species assemblages to guide conservation efforts. We tested the relative influence of natural and anthropogenic factors on mammalian species richness and occupancy in temperate forests in Northeast Asia. Location: Northeast China. Methods: Camera-trapping data and multi-species occupancy models were used to estimate the...

The effect of sertraline on depression and associations with persistent depression in survivors of HIV-related cryptococcal meningitis

Sarah Lofgren & David Boulware
Background: Depression is associated with worse outcomes in persons living with HIV/AIDS and has a prevalence more than three times as high as in the general population. Despite this, there are few randomized studies of antidepressants in HIV-infected Africans. Methods: We enrolled 460 HIV-infected Africans with cryptococcal meningitis into a randomized clinical trial of adjunctive sertraline vs placebo (2015-2017). We screened for clinical depression using the Center for Epidemiologic Studies Depression Scale (CES-D) at one...

Data from: Relaxation of putative plant defenses in a tropical agroecosystem

Lauren Carley & Susan Letcher
Evidence of the effects of agriculture on natural systems is widespread, but potential evolutionary responses in non-target species are largely uncharacterized. To explore whether exposure to agrochemicals may influence selective pressures and phenotypic expression in non-agricultural plant populations, we characterized the expression of putative anti-herbivore defense phenotypes in three non-agricultural species found upstream and downstream of irrigated rice fields in Guanacaste Province, Costa Rica. We found that plants downstream of chemically intensive agriculture showed shifts...

Beyond leaf habit: generalities in plant function across 97 tropical dry forest tree species

German Vargas G., Tim J. Brodribb, Juan M. Dupuy, Roy González‐M., Catherine M. Hulshof, David Medvigy, Tristan A. P. Allerton, Camila Pizano, Beatriz Salgado‐Negret, Naomi B. Schwartz, Skip J. Van Bloem, Bonnie G. Waring & Jennifer S. Powers
Leaf habit has been hypothesized to define a linkage between the slow-fast plant economic spectrum and the drought resistance-avoidance trade-off in tropical forests (‘slow-safe versus fast-risky’). However, variation in hydraulic traits as a function of leaf habit has rarely been explored for a large number of species. We sampled leaf and branch functional traits of 97 tropical dry forest tree species from four sites to investigate whether patterns of trait variation varied consistently in relation...

Seasonal NDVI data for a biodiversity and consumer removal experiment at the University of Minnesota's Cedar Creek Ecosystem Science Reserve (2009 - 2016)

Max Zaret
Plant biodiversity and consumers (herbivores, pathogens, and mutualists) are important mediators of energy and carbon fluxes in grassland ecosystems. Although the role of consumers and plant diversity in controlling peak-season biomass production has been characterized, knowledge of their roles in within-season variation of energy and carbon flux remains poorly understood. Here we measure variation in consumer and plant diversity control of plant biomass production throughout the growing season and their impact on plant biomass phenology...

Nolan Bornowski, Kathryn J. Michel, John P. Hamilton, Shujun Ou, Arun S. Seetharam, Jerry Jenkins, Jane Grimwood, Chris Plott, Shengqiang Shu, Jayson Talag, Megan Kennedy, Hope Hundley, Vasanth R. Singan, Kerrie Barry, Chris Daum, Yuko Yoshinaga, Jeremy Schmutz, Candice N. Hirsch, Matthew B. Hufford, Natalia De Leon, Shawn M. Kaeppler & C. Robin Buell
The Stiff Stalk heterotic group is an important source of inbreds used in U.S. commercial hybrid production. Founder inbreds B14, B37, B73, and to a lesser extent B84, are found in the pedigrees of a majority of commercial seed parent inbred lines. We created high-quality genome assemblies of B84 and four ex-Plant Variety Protection lines LH145 representing B14, NKH8431 of mixed descent, PHB47 representing B37, and PHJ40 which is a Pioneer Hi-Bred early Stiff Stalk...

Data supporting: Evaluation of neurobehavioral abnormalities and immunotoxicity in response to oral imidacloprid exposure in domestic chickens (Gallus callus domesticus)

Dana M Franzen-Klein
Domestic chickens (Gallus gallus domesticus) were exposed to imidacloprid by gavage once daily for 7 consecutive days at 0, 0.03, 0.34, 3.42, 10.25, and 15.50 mg/kg/day (n = 20 per group; 5 6-week-old males, 5 6-week-old females, 5 9-week-old males, and 5 9-week-old females). The severity and duration of neurobehavioral abnormalities were recorded. Components of the innate and adaptive immune system were assessed with 7 standard functional assays. Temporary neurobehavioral abnormalities were observed in a...

Aboveground net primary productivity in regenerating seasonally dry tropical forest: contributions of rainfall, forest age, and soil

Justin Becknell, German Vargas, Daniel Pérez‐Aviles, David Medvigy & Jennifer Powers
Identifying factors controlling forest productivity is critical to understanding forest-climate change feedbacks, modeling vegetation dynamics, and carbon finance schemes. However, little research has focused on productivity in regenerating tropical forest which are expanding in their fraction of global area have an order of magnitude larger carbon uptake rates relative to older forest. We examined aboveground net primary productivity (ANPP) and its components (wood production and litterfall) over ten years in forest plots that vary in...

Research funding for male reproductive health and infertility in the UK and USA [2016 – 2019]

Eva Gumerova, Christopher De Jonge & Christopher Barratt
There is a paucity of data on research funding levels for male reproductive health (MRH). We investigated the research funding for MRH and infertility by examining publicly accessible webdatabases from the UK and USA government funding agencies. Information on the funding was collected from the UKRI-GTR, the NIHR’s Open Data Summary, and the USA’s NIH RePORT webdatabases. Funded projects between January 2016 and December 2019 were recorded and funding support was divided into three research...

Data and code from: Mixed infection, risk projection and misdirection: Interactions among pathogens alter links between host resources and disease

Alexander Strauss, Lucas Bowerman, Anita Porath-Krause, Eric Seabloom & Elizabeth Borer
A growing body of literature links resources of hosts to their risk of infectious disease. Yet most hosts encounter multiple pathogens, and projections of disease risk based on resource availability could be fundamentally wrong if they do not account for interactions among pathogens within hosts. Here, we measured infection risk of grass hosts (Avena sativa) exposed to three naturally-co-occurring viruses either singly or jointly (barley and cereal yellow dwarf viruses [B/CYDVs]: CYDV-RPV, BYDV-PAV, and BYDV-SGV)...

Stand-level variation drives canopy water storage by non-vascular epiphytes across a temperate-boreal ecotone

Daniel Stanton, Tana Route, Abby Glauser, Kate Hembre & Abigail Meyer
Epiphytes, including bryophytes and lichens, can significantly change the water interception and storage capacities of forest canopies. However, despite some understanding of this role, empirical evaluations of canopy and bole community water storage capacity by epiphytes are still quite limited. Epiphyte communities are shaped by both microclimate and host plant identity, and so the canopy and bole community storage capacity might also be expected to vary across similar spatial scales. We estimated canopy and bole...

Data from: Bioregions are predominantly climatic for fishes of northern lakes

Charlie Loewen, Donald Jackson, Cindy Chu, Karen Alofs, Gretchen Hansen, Andrew Honsey, Charles Minns & Kevin Wehrly
Aim: Recurrent species assemblages integrate important biotic interactions and joint responses to environmental and spatial filters that enable local coexistence. Here, we applied a bipartite (site-species) network approach to develop a natural typology of lakes sharing distinct fish faunas and provide a detailed, hierarchical view of their bioregions. We then compared the roles of key biogeographic factors to evaluate alternative hypotheses about how fish communities are assembled from the regional species pool. Location: Ontario, Canada...

Can we implement mechanistic niche models without measuring traits?

Tom Radomski
Despite increasing demand for more mechanistic models of species’ distributions, they remain difficult to implement due to their intense data requirements. Here, we suggest that three existing tools might help researchers estimate missing trait data that can fill necessary requirements: phylogenetic imputation (incorporating evolutionary relationships into the imputation process), allometry, and biophysics. These tools can bridge the gap between species for which we have fairly little data and ecological models of their distributions. We focus...

Sudden Unexpected Death in Epilepsy: A Personalized Prediction Tool

Ashwani Jha, Cheongeun Oh, Dale Hesdorffer, Beate Diehl, Sasha Devore, Martin Brodie, Torbjörn Tomson, Josemir W. Sander, Thaddeus S. Walczak & Orrin Devinsky
Objective: To develop and validate a tool for individualised prediction of Sudden Unexpected Death in Epilepsy (SUDEP) risk, we re-analysed data from one cohort and three case-control studies undertaken 1980-2005. Methods: We entered 1273 epilepsy cases (287 SUDEP, 986 controls) and 22 clinical predictor variables into a Bayesian logistic regression model. Results: Cross-validated individualized model predictions were superior to baseline models developed from only average population risk or from generalised tonic-clonic seizure frequency (pairwise difference...

Conspecific leaf litter induces negative feedbacks in Asteraceae seedlings

Max Zaret & Briana Whitaker
The plant soil feedback (PSF) framework has been instrumental in quantifying soil microbial impacts on plant fitness and mechanisms for species coexistence. The recent extension of the PSF framework to microbes associated with aboveground tissues of plants, termed here as plant phyllosphere feedbacks (PPFs), can also help determine the role of aboveground microbes as drivers of plant-plant interactions. However, experimental tests of PPFs in wild hosts is nascent and their prevalence across diverse hosts remains...

When text simplification is not enough: Could a graph-based visualization facilitate consumers’ comprehension of dietary supplement information?

Xing He, Rui Zhang, Jordan Alpert, Sicheng Zhou, Terrence Adam, Aantaki Raisa, Yifan Peng, Hansi Zhang, Yi Guo & Jiang Bian
Background: Dietary supplements are widely used. However, dietary supplements are not always safe. For example, an estimated 23,000 emergency room visits every year in the United States were attributed to adverse events related to dietary supplement use. With the rapid development of the Internet, consumers usually seek health information including dietary supplement information online. To help consumers access quality online dietary supplement information, we have identified trustworthy dietary supplement information sources and built an evidence-based...

Performance and refinement of nitrogen fertilization tools

Curtis Ransom, Jason Clark, Gregory Bean, Christopher Bandura, Matthew Shafer, Newell Kitchen, James Camberato, Paul Carter, Richard Ferguson, Fabián Fernández, David Franzen, Carrie Laboski, David Myers, Emerson Nafziger & John Sawyer
Improving corn (Zea mays L.) N management is pertinent to economic and environmental objectives. However, there are limited comprehensive data sources to develop and test N fertilizer decision aid tools across a wide geographic range of soil and weather scenarios. Therefore, a public-industry partnership was formed to conduct standardized corn N rate response field studies throughout the U.S. Midwest. This research was conducted using a standardized protocol at 49 site-years across eight states over the...

Migration and tolerance shape host behavior and response to parasites infection

Dongmin Kim & Allison Shaw
Numerous theoretical models have demonstrated that migration, a seasonal animal movement behavior, can minimize the risks and costs of parasite infection. Past work on migration-infection interactions assumes migration is the only strategy available to organisms for dealing with the parasite infection, that is they migrate to a different environment to recover or escape from infection. Thus, migration is similar to the non-spatial strategy of resistance, where hosts prevent infection or kill parasites once infected. However,...

PacBio sequencing output increased through uniform and directional 5-fold concatenation

Celia Blanco, Nisha Kanwar, Irene A. Chen & Burckhard Seelig
Advances in sequencing technology have allowed researchers to sequence DNA with greater ease and at decreasing costs. Main developments have focused on either sequencing many short sequences or fewer large sequences. Methods for sequencing mid-sized sequences of 600-5,000 bp are currently less efficient. For example, the PacBio Sequel I system yields ~100,000-300,000 reads with an accuracy per base pair of 90-99%. We sought to sequence several DNA populations of ~870 bp in length with a...

Data from: Gravity and active acceleration limit the ability of killer flies (Coenosia attenuata) to steer towards prey when attacking from above

Sergio Rossoni, Samuel Fabian, Gregory Sutton & Paloma Gonzalez-Bellido
Insects that predate aerially usually contrast prey against the sky and attack upwards. However, killer flies (Coenosia attenuata) can attack prey flying below them, performing what we term 'aerial dives'. During these dives, killer flies accelerate up to 36 m/s2. Although the trajectories of the killer fly's dives appear highly variable, proportional navigation explains them, as long as the model has the lateral acceleration limit of a real killer fly. The trajectory's steepness is explained...

Model data for: Drawdown of atmospheric pCO2 via dynamic particle export stoichiometry in the ocean twilight zone

Tatsuro Tanioka & Katsumi Matsumoto
Understanding the global carbon cycle is key to understanding the climate system. One of the large unknowns is the processes happening in the twilight zone of the ocean. Here, we focus on how elemental stoichiometry of particulate organic matter in the twilight zone affects the strength of the biological pump and atmospheric CO2. We show through modeling that atmospheric CO2 is very sensitive to the change in C:P ratio in the twilight zone. Numerous model...
