Plant species percent cover data:Biodiversity: A field test of biofuel production and ground-water quality
Bioenergy could be an important part of the solution to the projected climate problems of the future, and in addition could provide auxiliary ecological services. The project described here aims to parameterize expected benefits of diverse prairie biofuel plantations for groundwater quality, and also to further evaluate its biofuel potential. This project, done in cooperation with the USGS, grows out of purely scientific discoveries in other Cedar Creek experiments. We know that diverse prairie systems are better able to retain inorganic nitrogen than monoculture systems (e.g., Dijkstra etal. 2007). However, nitrogen is just one pollutant of many being delivered to surface-water and ground-water from agricultural systems. There are a number of others including phosphorus, pesticides, and veterinary pharmaceuticals. This fact combined with the rising demand for corn grain ethanol could lead to further declines in the water quality of agricultural regions in the United States. Perennial vegetative buffers, in particular diverse prairies and/or hay (CRP), are proposed solutions. The vegetation in such buffers can be used for biofuel and simultaneously appear to be attenuate leaching of agricultural compounds through the unsaturated zone to groundwater. This 3-year cooperative USGS and UMN study will (1) examine the ability of prairies and hay (CRP) to attenuate leaching of agricultural compounds to ground-water (2) compare biofuel production of four cropping systems: diverse prairie, hay (CRP), corn grown with chemical fertilizer, and corn grown with a combination of manure and chemical fertilizer, (3) provide for future investigations into microbial antibiotic resistance and (4) provide a better understanding of the unsaturated zone hydrology and shallow groundwater recharge at Cedar Creek. The project will take place in the E120 field.

Aggregated frequencies of transcription initiations observed in FANTOM5 CAGE data on GRCm38, including alignments with low mapping qualities
<p><strong>Overview</strong></p> <p>Aligned reads of the FANTOM5 CAGE data have been used after filtering (ones with mapping quality less than 20 or percent identity less than 85% were discarded) for general purpose, resulting in the data set consisting of only the reads aligned with confidence. The filtering process made possible to interpret the data without ambiguity, however it also limited interpretation of paralogous or duplicated regions within the genome. Here all of the 5'-ends of the CAGE read alignments, including the ones with low mapping quality, were counted. The counts in the individual profiles were aggregated and summed up. </p> <p>This data set is produced for mouse, in the same way to the one for human data set http://doi.org/10.5281/zenodo.1410835</p> <p> </p> <p><strong>Data files</strong></p> <p>The resulting data files are formatted as bigWig (https://genome.ucsc.edu/FAQ/FAQformat.html#format6.1). '*.fwd.bw' and '*.rev.bw' represent forward and reverse strand on the genome, respectively. </p> <p> </p> <p><strong>Methods</strong></p> <p>The BAM files under https://fantom.gsc.riken.jp/5/datafiles/reprocessed/mm10_v7/basic/ were subjected to 5'-end counting by bedtools v2.27.1 (https://github.com/arq5x/bedtools2), followed by conversion into bigWig with jksrc v366 (http://hgdownload.cse.ucsc.edu/admin/).</p>

Connecting digital citizen science data quality issue to solution mechanism table
<p>A table explaining how to solve data quality issues in digital citizen science. A total of 35 issues and 64 mechanisms to solve them are proposed</p>
Data from: Sleep duration, midday napping and sleep quality and incident stroke: the Dongfeng-Tongji cohort
Objective: To investigate the associations of sleep duration, midday napping and sleep quality, and change in sleep duration with risk of incident stroke and stroke subtypes. Methods: Among 31750 participants aged 61.7 years on average at baseline from the Dongfeng-Tongji cohort, we used Cox regression models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for incident stroke. Results: Compared with sleeping 7-<8 h/night, those reporting longer sleep duration (≥9 h/night) had a greater risk of total stroke (HR, 1.23; 95% CI, 1.07-1.41), while shorter sleep (<6 h/night) had no significant effect on stroke risk. The HR (95% CI) of total stroke was 1.25 (1.03-1.53) for midday napping >90 min vs 1-30 min. The results were similar for ischemic stroke. Compared with good sleep quality, those with poor sleep quality showed a 29%, 28% and 56% higher risk of total, ischemic, and hemorrhagic stroke, respectively. Moreover, we observed significant joint effects of sleeping ≥9 h/night and midday napping >90 min (HR, 1.85; 95% CI, 1.28-2.66), and sleeping ≥9 h/night and poor sleep quality (HR, 1.82; 95% CI, 1.33-2.48) on risks of total stroke. Furthermore, compared with persistently sleeping 7-9 h/night, those persistently slept ≥9 h/night or switched from 7-9 h to ≥9 h/night had a higher risk of total stroke. Conclusions: Long sleep duration, long midday napping and poor sleep quality were independently and jointly associated with higher risks of incident stroke. Persistently long sleep duration or switch from average to long sleep duration increased the risk of stroke.
Data from: Sperm quality, aggressiveness and generation turnover can facilitate unidirectional Y chromosome introgression across the European house mouse hybrid zone
The widespread and locally massive introgression of Y chromosomes of the eastern house mouse (<i>Mus musculus musculus</i>) into the range of the western subspecies (<i>M. m. domesticus</i>) in Central Europe calls for an explanation of its underlying mechanisms. Given the paternal inheritance pattern, obvious candidates for traits mediating the introgression are characters associated with sperm quantity and quality. We can also expect traits such as size, aggression, or the length of generation cycles to facilitate the spread. We have created two consomic strains carrying the non-recombining region of the Y chromosome of the opposite subspecies, allowing us to study introgression in both directions, something impossible in nature due to the unidirectionality of introgression. We analysed several traits potentially related to male fitness. Transmission of the <i>domesticus</i> Y onto the <i>musculus</i> background had negative effects on all studied traits. Likewise , <i>domesticus</i> males possessing the <i>musculus</i> Y had, on average, smaller body and testes and lower sperm count than the parental strain. However, the same consomic males tended to produce less dissociated sperm heads, to win more dyadic encounters, and to have shorter generation cycles than pure <i>domesticus</i> males. These data suggest the <i>domesticus</i> Y is disadvantageous on the <i>musculus</i> background while introgression in the opposite direction can confer a recognizable, though not always significant, selective advantage. Our results are thus congruent with the unidirectional <i>musculus</i>→domesticus Y chromosome introgression in Central Europe. In addition to some previous studies, they show this to be a multifaceted phenomenon demanding a multidisciplinary approach.
Data from: Associations between habitat quality, body size, and reproductive fitness in the alpine endemic spider Vesubia jugorum
Aim. In theory, the highest-quality habitat across a species' range should support individuals with the highest fitness, making it possible to evaluate the outputs of species distribution models (SDM) by exploring the relation between habitat quality and functional traits related to species' fitness. However, this relation has been tested almost exclusively in plants. We investigated the degree to which morphological and reproductive traits of an alpine spider varied along a gradient of habitat quality projected via species distribution models. Location. Southwestern Alps (France and Italy) Time period. 2007–2018 Major taxa studied. Vesubia jugorum (Arachnida: Araneae: Lycosidae) Methods. We used climatic, topographical and geomorphological variables at a resolution of 250 m to model habitat quality for V. jugorum, with multiple algorithms (generalized additive models, boosted regression trees, and maximum entropy models). We collected spiders in the field and measured their body size and egg-case size (a functional trait related to reproductive success). We tested the relation between functional traits and habitat quality with linear mixed models. Results. All SDM algorithms we tested fit the data well, with similar explanatory ability. Models revealed a positive relation between the probability of presence and cumulative precipitation and percentage of rock. An additional important variable in the SDMs was duration of snow coverage, with optimal projected habitat quality between 40 and 100 days/year with snow. Modeled habitat quality was positively associated with maximum body and egg-case size. Main conclusions. Our work provides evidence of a positive association between projected habitat quality and traits of a terrestrial invertebrate. A model that fits the data well potentially can be used to predict variations in species' traits, thus offering an experimental test of SDM projections with field-collected data. We encourage SDM users to incorporate data on functional traits into their modeling fitting exercises.
Data from: Findings from an exploration of a social network intervention to promote diet quality and health behaviours in older adults with COPD: a feasibility study
<p><span><b>Background: </b>Diet quality in older people with Chronic Obstructive Pulmonary Disease (COPD) is associated with better health and lung function. Social factors, such as social support, social networks and participation in activities, have been linked with diet quality in older age. A social network tool – GENIE (Generating Engagement in Network Involvement) – was implemented in a COPD community care context. The study aimed to assess the feasibility of the GENIE intervention to promote diet quality and other health behaviours in COPD. </span></p> <p><span><b>Methods:</b> Twenty-two community-dwelling older adults with COPD were recruited from a local COPD Service. Participants were offered usual care or the GENIE intervention. Process evaluation methods were used to assess intervention implementation, context and mechanisms of impact; <a name="_Hlk11247522">these included observations of patient interactions with the intervention, documented in observational field notes and in films of a patient group discussion.</a> Diet quality was assessed by food frequency questionnaire; 'prudent' diet scores were used to describe diet quality at baseline and at 3-month follow-up. Change in diet quality was expressed per month, from baseline to follow-up.</span></p> <p><b>Results: </b>Feasibility data showed that the GENIE intervention could be implemented in this sample of community-living older people. The intervention was acceptable to clinicians and older people with COPD, especially for those with less severe disease, when facilitated appropriately and considering the levels of literacy of participants. There was no significant change in diet quality in the intervention group over the follow-up period (median change in prudent diet score per month, (interquartile range (IQR)): 0.03, (-0.24 – 0.07)); whereas an overall fall in diet quality was observed in the control group (-0.15, (-0.24 – 0.03)).</p> <p><span><b>Conclusion: </b>The process evaluation findings suggest that this intervention is feasible and acceptable to both patients and clinicians. Although the sample size achieved in this study was small, findings suggest that the intervention may have a protective effect against declines in diet quality, and other health behaviours, in an older COPD population. Findings from this feasibility study indicate that further evaluation of the GENIE intervention is warranted in a larger study, with a longer follow-up.</span></p> <p> </p> <p> </p>
Data from: Quality of stroke care and outcomes by sex: a pooled analysis including 19,000 participants
Objective: To explore the sex differences in outcomes and management after stroke using a large sample with high-quality international trial data. Methods: Individual participant data were obtained from five acute stroke randomized controlled trials. Data were obtained on demographics, medication use, in-hospital treatment and functional outcome. Study-specific crude and adjusted models were used to estimate sex differences in outcomes and management, and then pooled using random-effects meta-analysis. Results: There were 19,652 participants of whom 7721 (40%) were women. After multivariable adjustments, women with ischemic stroke had higher survival at 3 to 6 months (odds ratio [OR] 0.82; 95% confidence interval [CI] 0.70-0.97), higher likelihood of disability (OR 1.20; 95% CI 1.06-1.36) and worse quality of life (weighted mean difference -0.07, 95% CI -0.09—0.04). For management, women were more likely admitted to an acute stroke unit (OR 1.17, 95% CI 1.01-1.34), but less likely intubated (OR 0.58, 95% CI 0.36-0.93), treated for fever (OR 0.82, 95% CI 0.70-0.95) and admitted to an intensive care unit (OR 0.83, 95% CI 0.74-0.93). For pre-admission medications, women had higher odds of being prescribed antihypertensive agents (OR 1.22, 95% CI 1.13-1.31) and lower odds of being prescribed antiplatelets (OR 0.86; 95% CI 0.79-0.93), glucose lowering (OR 0.86; 95% CI 0.78-0.94) and lipid lowering agents (OR 0.85; 95% CI 0.77-0.94). Conclusions: This analysis suggest that women who had ischemic stroke had better survival but were also more disabled and had poorer quality of life. Variations in hospital and out-of-hospital management may partly explain the disparities.
Data from: Mite load predicts the quality of sexual color and locomotor performance in a sexually dichromatic lizard
Since Darwin, the maintenance of bright sexual colors has recurrently been linked to mate preference. However, the mechanisms underpinning such preferences for bright colors would not be resolved for another century. Likely, the idea of selection for colors that could decrease the chances of survival (e.g. flashy colors that can inadvertently attract predators) was perceived as counterintuitive. It is now widely-accepted that these extreme colors often communicate to mates the ability to survive despite a 'handicap' and act as honest signals of individual quality when they are correlated with the quality of other traits that are directly linked to individual fitness. Sexual colors in males are frequently perceived as indicators of infection resistance, in particular. Still, there remains considerable discord among studies attempting to parse the relationships between the variables associating sexual color and infection resistance, such as habitat type and body size. This discord may arise from complex interactions between these variables. Here, we ask if sexual color in male Florida scrub lizards (Sceloporus woodi) is an honest signal of resistance to chigger mite infection. To this end, we use linear modeling to explore relationships between mite load, different components of sexual color, ecological performance, body size, and habitat type. Our data show that that the brightness of sexual color in scrub lizards is negatively associated with the interaction between mite load and body size, and scrub lizards suffer decreased endurance capacity with increases in mite load. Our data also indicate that mite load, performance, and sexual color in male scrub lizards can vary between habitat types. Collectively these results suggest that sexual color in scrub lizards is an honest indicator of individual quality and further underscore the importance of considering multiple factors when testing hypotheses related to the maintenance of sexual color.
