title: Data from: Intravenous thrombolysis in patients with chronic kidney disease: A systematic review and meta-analysis

description: Objective We sought to determine the association of chronic
 kidney disease (CKD) with the safety and efficacy of intravenous
 thrombolysis (IVT) among acute ischemic stroke (AIS) patients. Methods
 Systematic review and pairwise meta-analysis of studies involving patients
 with CKD undergoing IVT for AIS were conducted to evaluate the following
 outcomes: symptomatic intracranial hemorrhage (sICH), asymptomatic and any
 ICH, in-hospital and 3-month mortality, 3-month favorable functional
 outcome (FFO, mRS 0-1) and 3-month functional independence (FI, mRS 0-2).
 CKD was defined using estimated glomerular filtration rate (eGFR) ranging
 from mild (eGFR: 60-89ml/min), moderate (eGFR: 30-59ml/min) and severe
 (eGFR: 15-29ml/min). Results We identified 20 studies comprising 60,486
 AIS patients treated with IVT. In unadjusted analyses, CKD was associated
 with sICH according to NINDS (7 studies; OR=1.41, 95%CI: 1.19–1.67) and
 ECASS-II (9 studies; OR=1.37, 95%CI: 1.01–1.85) definitions, any ICH (8
 studies; OR=1.42, 95%CI: 1.18–1.70), 3-month mortality (9 studies; OR =
 2.20, 95%CI: 1.72–2.81), 3-month FFO (8 studies; OR=0.58, 95%CI:
 0.47–0.72) and 3-month FI (8 studies; OR=0.57, 95%CI: 0.46–0.71). In
 adjusted analyses, CKD was associated with sICH according to NINDS (4
 studies; ORadj=1.34, 95%CI: 1.01–1.79) and ECASS-II (3 studies;
 ORadj=2.08, 95%CI 1.27–3.43) definitions, any ICH (6 studies; ORadj=1.41,
 95%CI 1.01–1.97), in-hospital mortality (2 studies; ORadj =1.19; 95%CI,
 1.09-1.30) and 3-month FFO (6 studies; ORadj=0.80, 95%CI 0.70–0.92).
   Conclusions After adjustment for confounders in this pairwise
 meta-analysis, moderate-severe CKD is associated with increased risks of
 intracranial hemorrhage and worse functional outcomes among AIS patients
 treated with IVT.

title: Stratified Reward Structures and Competition in Markets for Creative Production

description: Stratified reward structures have emerged as a universal feature of modern
 society, but their implications on the producers and consumers of creative
 work are not fully understood. We conducted an online experiment to test
 the effects of reward stratification in peer-reviewed creative production
 markets. We find that competition induced by stratification shapes the
 evolution of creative production, and that the quality of each tier in a
 stratified market is consistent with its position in the hierarchy. The
 top tier maintains high-quality standards by attracting many submissions
 and by filtering its output, operating as an effective sorting device for
 budget-constrained consumers. However, stratification generates higher
 levels of inequality among producers, leading to higher rates of
 market-exit for those lagging behind. We discuss the broad implications of
 reward stratification and artificial scarcity in hypercompetitive
 environments, contributing to the debate on cumulative advantage and the
 allocation of funding and recognition in science.

title: Data from: Synchrotron-X-ray fluorescence analysis reveals diagenetic alteration of fossil melanosome trace metal chemistry

description: A key feature of the pigment melanin is its high binding affinity for
 trace metal ions. In modern vertebrates trace metals associated with
 melanosomes, melanin-rich organelles, can show tissue- and taxon-specific
 distribution patterns. Such signals preserve in fossil melanosomes,
 informing on the anatomy and phylogenetic affinities of fossil
 vertebrates. Fossil and modern melanosomes, however, often differ in trace
 metal chemistry; in particular, melanosomes from fossil vertebrate eyes
 are depleted in Zn and enriched in Cu relative to their extant
 counterparts. Whether these chemical differences are biological, or
 taphonomic, in origin is unknown, limiting our ability to use melanosome
 trace metal chemistry to test palaeobiological hypotheses. Here, we use
 maturation experiments on eye melanosomes from extant vertebrates and
 synchrotron rapid scan-X-ray fluorescence analysis to show that thermal
 maturation can dramatically alter melanosome trace element chemistry. In
 particular, maturation of melanosomes in Cu-rich solutions results in
 significant depletion of Zn, likely due to low pH and competition effects
 with Cu. These results confirm fossil melanosome chemistry is susceptible
 to alteration due to variations in local chemical conditions during
 diagenesis and that maturation experiments can provide essential data on
 melanosome chemical taphonomy required for accurate interpretations of
 preserved chemical signatures in fossils.

title: Data from: The effects of river algae and porewater flow on the feeding of juvenile mussels

description: Juvenile mussels enter the benthos after excysting from a fish host and
 settling to the bottom where they inhabit the interstitial zone in
 rivers.  We examined the algal composition in the surface water
 and pore waters in different locations in a temperate river (Thames River)
 in Southern Ontario.  Surprisingly, algal concentration (C) was
 ~9× higher in pore water versus surface water, varied spatially in the
 riverbed (downstream of boulders &gt; upstream of boulders and
 non-bedform regions), and pennate diatoms were the most abundant taxon in
 the pore waters.  We examined the clearance rate (CR; mass of
 suspended material removed from the water per unit time and mussel) of
 recently metamorphosed juvenile unionid mussels (3 – 4 week old Lampsilis
 siliquoidea, Fatmuckets) exposed to pore water and surface water in a
 paddle-wheel flow chamber at different water velocities (U). 
 Juvenile CR based on chlorophyll a fluorescence was ~2× higher on pore
 water versus surface water and CR based on a specific algal taxon,
 identified via flow cytometry, varied with its initial
 concentration.  Chesson’s feeding electivity index revealed that
 mussels removed 5 chlorophyte taxa in proportion to their concentration in
 the water (i.e., removed at random) but they removed 5 diatom taxa in
 greater proportion (i.e., selected for by juvenile mussels) across the
 range of algal flux (J = UC) examined.  This study provides
 evidence of the importance of diatoms in pore waters to juvenile
 mussels.  It also reveals elements of the physico-chemical
 environment used by juvenile mussels, which should be considered in their
 conservation.

title: Different qPCR master mixes influence telomere primer binding within and between bird species

description: The analysis of telomere dynamics in birds is a growing research field
 providing important findings on ecological and environmental variations in
 individuals' aging, fitness and lifespan. Real‐time quantitative PCR
 (qPCR) has gained much interest for the evaluation of telomere length in
 birds. However, the assessment of several key preanalytical and analytical
 factors to optimize the method for achieving reproducible results, and the
 influence of these factors on the conclusions of each study, have been
 generally overlooked. In this study, we assessed the performance of eight
 commercially‐available qPCR master mixes in the amplification of telomere
 fragments in two bird species (zebra finch Taeniopygia
 guttata, and red‐billed chough Pyrrhocorax pyrrhocorax).
 We observed that qPCR master mixes influence the telomere primer binding
 to target sequences and the amplification specificity within and between
 bird species, although PCR amplification efficiencies were very close to
 100% for all master mixes. These findings indicated that the suitability
 of the master mix and other analytical factors must be carefully evaluated
 before starting a telomere dynamics study, especially when the technique
 has not previously been used in the species. We also showed that optimal
 PCR amplification efficiencies do not translate to good qPCR telomere
 assays, and that inference about amplification specificity based only on
 melting curve data can lead to misleading conclusions. Overall, this work
 highlights the complexity of qPCR optimization for the study of telomere
 length in birds.

title: Drivers of the ecological stoichiometry of plant C/N/P ratios due to negative density dependence in wheat

description: Average organ weights, C, N, P concentrations, and biomass
 root-shoot ratios (including and excluding tassel weight) of each
 plant in different periods and densities were collated, and used to
 calculate C/N and N/P ratios. Graphs were drawn in
 Excel, and tests of significance were conducted in SPSS 22
 software. When the relationship between tassel weight and
 root-shoot ratio per plant was regressed, the
 aboveground biomass of the root-shoot ratio per plant did not include
 tassel weight so as to maintain the independence between the
 dependent and independent variables.

title: High temperature induces transcriptomic changes in Crassostrea gigas that hinder progress of ostreid herpes virus (OsHV-1) and promote survival

description: Of all environmental factors, seawater temperature plays a decisive role
 in triggering marine diseases. Like fever in vertebrates, high seawater
 temperature could modulate the host response to pathogens in ectothermic
 animals. In France, massive mortality of Pacific oysters, Crassostrea
 gigas, caused by the ostreid herpesvirus 1 (OsHV-1) is markedly reduced
 when temperatures exceed 24°C in the field. In the present study we assess
 how high temperature influences the host response to the pathogen by
 comparing transcriptomes (RNA sequencing) during the course of
 experimental infection at 21°C (reference) and 29°C. We show that high
 temperature induced host physiological processes that are unfavorable to
 the viral infection. Temperature influenced the expression of transcripts
 related to the immune process and increased the transcription of genes
 related to the apoptotic process, synaptic signaling and protein processes
 at 29°C. Concomitantly, the expression of genes associated with
 catabolism, metabolite transport, macromolecule synthesis and cell growth
 remained low from the first stage of infection at 29°C. Moreover, viral
 entry into the host might have been limited at 29°C by changes in
 extracellular matrix composition and protein abundance. Overall, these
 results provide new insights into how environmental factors modulate
 host–pathogen interactions.

title: Deficits in functional trait diversity following recovery on coral reefs

description: The disturbance regimes of ecosystems are changing, and prospects for
 continued recovery remain unclear. New assemblages with altered species
 composition may be functionally deficient. Alternatively, key functional
 traits may be sustained by species that replace those in decline (response
 diversity). Here, we quantify the recovery and response diversity of coral
 assemblages using case studies of disturbance in three locations. Despite
 return trajectories of coral cover, the original assemblages with diverse
 functional attributes failed to recover at each location. Response
 diversity and the reassembly of trait space was limited, and varied
 according to biogeographical differences in the attributes of dominant,
 rapidly recovering species. The deficits in recovering assemblages
 identified here suggest that the return of coral cover cannot assure the
 reassembly of reef trait diversity, and that shortening intervals between
 disturbances can limit recovery among functionally important species.
description: Trait data for 44 taxonomic groups is coded according to Table 1
 in the main text, and "raw" and "cat" refer to raw and
 categorical data, respectively (CS=colony size, CW = corallite width, SD =
 skeletal density, GR = Growth Rate, CH = colony height, IB = interstitial
 branch spacing, SV = surface area to volume ratio). 
 Abundance data is included for 44 taxonomic groups at three time
 points (1 = predisturbance, 2 = after disturbance, 3 = recovering), at
 three locations (Rio Bueno, Lizard Island, and Moorea).

title: Topological structure and dynamics of three-dimensional active nematics

description: Topological structures are effective descriptors of the nonequilibrium
 dynamics of diverse many-body systems. For example, motile, point-like
 topological defects capture the salient features of two-dimensional active
 liquid crystals composed of energy-consuming anisotropic units. We
 dispersed force-generating microtubule bundles in a passive colloidal
 liquid crystal to form a three-dimensional active nematic. Light-sheet
 microscopy revealed the temporal evolution of the millimeter-scale
 structure of these active nematics with single-bundle resolution. The
 primary topological excitations are extended, charge-neutral disclination
 loops that undergo complex dynamics and recombination events. Our work
 suggests a framework for analyzing the nonequilibrium dynamics of bulk
 anisotropic systems as diverse as driven complex fluids, active
 metamaterials, biological tissues, and collections of robots or organisms.

title: Vertical transmission of a nematode from female lizards to the brains of their offspring

description: Parasites have evolved a diversity of life styles that exploit the biology
 of their hosts. Some nematodes that parasitize mammals pass via the
 placenta or milk from one host to another. Similar cases of vertical
 transmission have never been reported in avian and non-avian reptiles,
 suggesting that egg laying may constrain themeans of parasite
 transmission. However, here we report the first incidence of transovarial
 transmission of a previously undescribed nematode in an egg-laying
 amniote, the common wall lizard, Podarcis muralis . Nematodes enter the
 developing brain from the female ovary early in embryonic development.
 Infected lizard embryos develop normally and hatch with nematodes residing
 in their braincase. We present a morphological and molecular phylogenetic
 characterization of the nematode and suggest that particular features of
 lizard biology that are absent from birds and turtles facilitated the
 evolutionary origin of this novel life history.

title: Fluctuated water depth with high nutrient concentrations promote the invasiveness of Wedelia trilobata in wetland

description: The distribution of invasive and native species in wetlands is determined
 by hydrological conditions; whereas conditions such as water depth
 fluctuations, variations in the nutrient concentrations are expected to
 affect the growth and physiological traits of plants. For the assessment
 of such effects, we conduct greenhouse experiment with three factors; 1)
 water depth of 5 cm and 15 cm (static and fluctuated);
 2) three levels of nutrient concentrations (i) full‐strength Hoagland
 solution (N1), (ii) ¼‐strength Hoagland solution (N2), and
 (iii) 1/8‐strength Hoagland solution (N3); and 3) species,
 invasive Wedelia trilobata (L.) and its congener,
 native Wedelia chinensis (Osbeck.) under mono and mixed
 culture. Water depth of 5 cm combined with any of the nutrient
 treatments significantly restrained the photosynthesis, intracellular
 CO2 concentration and leaf chlorophyll of both W.
 trilobata and W. chinensis. Increase in the water depth
 to 15 cm with low‐nutrient treatment N3 did not sustain the
 physiological traits of W. chinensis under mono and
 mixed planting. A great loss was noted in the growth of W.
 chinensis at 15 cm static and fluctuated water depth
 with low‐nutrient treatment (N3) and under mixed culture. In addition,
 water depth fluctuations with both low‐ and high‐nutrient treatments
 significantly affected the root‐shoot ratio, relative growth rate, and
 interspecific interaction among these two species. W.
 trilobata benefited more from competitive interaction index (CII)
 under fluctuated water depth at 15 cm with high nutrients, and
 the value of CII was clearly positive. Therefore, higher competitive
 ability may contribute to the invasiveness of W.
 trilobata in wetlands.
description: All data was collect during the experiment at different
 intervals. Fresh-weight of shoot, dry-weight of shoot,
 fresh-weight of root, dry-weight of root, total fresh weight of a plant
 and total dry biomass of a plant were measured by using weighing
 scale. Physiological parameters such as net photosynthetic rate, stomatal
 conductance and intercellular CO<sub>2</sub> concentration
 were measured by using a portable LI-6400XT, <i>Lincoln</i>,
 USA photosynthesis measurement system. All these data were recorded during
 full-sunshine at 9:30–11:30 a.m. once a week during treatments. For
 leaf chlorophyll
 measurement,<b> </b>Plant chlorophyll meter, Oakoch OK-Y104,
 made in China, was used to measure the leaf chlorophyll (Chl) contents
 (SPAD).  The chlorophyll was noted from the same leaves which were used
 for photosynthetic measurements.
description: The dataset is based on the original experimental data which were
 recored two times per week during whole experiment. All the values are
 presented in the dataset files, there is no missing values.

title: Data from: Slow oscillation-spindle coupling predicts enhanced memory formation from childhood to adolescence

description: Precise temporal coordination of slow oscillations (SO) and sleep spindles
 is a fundamental mechanism of sleep-dependent memory consolidation. SO and
 spindle morphology changes considerably throughout development.
 Critically, it remains unknown how the precise temporal coordination of
 these two sleep oscillations develops during brain maturation and whether
 their synchronization indexes the development of memory networks. Here, we
 use a longitudinal study design spanning from childhood to adolescence,
 where participants underwent polysomnography and performed a declarative
 word-pair learning task. Performance on the memory task was better during
 adolescence. After disentangling oscillatory components from 1/f activity,
 we found frequency shifts within SO and spindle frequency bands.
 Consequently, we devised an individualized cross-frequency coupling
 approach, which demonstrates that SO-spindle coupling strength increases
 during maturation. Critically, this increase indicated enhanced memory
 formation from childhood to adolescence. Our results provide evidence that
 improved coordination between SOs and spindles indexes the development of
 sleep-dependent memory networks.

title: Drivers of large-scale geographical variation in sexual systems of woody plants

description: Aim: Sexual systems strongly influence angiosperm evolution, and play
 important roles in community assembly and species responses to climate
 change. However, geographical variation in proportions of different sexual
 systems (dioecy, monoecy, and hermaphroditism) in response to changes in
 climate, life-history traits and evolutionary age remains poorly
 understood. Here, we map the geographical variation in proportions of
 different sexual systems and hypothesize that the prevalence of
 hermaphrodites increases with aridity due to their advantages in
 colonizing harsh environment, whereas dioecy is most successful in humid
 regions with tall-canopy vegetation and old floras. Location: China Time
 period: Current Major taxa studied: Woody angiosperms Methods: Using data
 on sexual systems and distributions of 10,449 woody species in China, we
 estimated the proportions of different sexual systems in local floras (50
 × 50 km grid cells). Spatial linear models, phylogenetic general linear
 models and structural equation models were used to compare the relative
 influences of climate, plant height and evolutionary age on geographical
 variation in proportions of different sexual systems. Results: We found
 contrasting geographical patterns in the proportions of different sexual
 systems. The proportions of dioecy and monoecy increased with plant height
 and were highest in humid regions with older floras, while that of
 hermaphroditism decreased with plant height and was highest in arid
 regions with younger floras. Plant height was the strongest correlate of
 sexual system frequency. Climate influenced sexual system frequency both
 directly and indirectly via its effects on plant height. Main conclusions:
 Our study provides the first continuous map of sexual system composition
 in woody floras over a large spatial scale. Our findings suggest that
 mature plant height, reflecting plant longevity, dominates geographical
 variation in sexual systems and that the proportions of different sexual
 systems in local floras may reflect their correlated evolution with traits
 in response to climate changes.

title: Environmental DNA detection of Arctic char (Salvelinus alpinus) in Irish lakes: development and application of a species-specific molecular assay

description: Populations of Arctic char (Salvelinus alpinus) inhabiting Irish lakes are
 undergoing a rapid decline. In order to aid monitoring of this species in
 Irish lakes, a species/specific qPCR assay was designed and subsequently
 tested for the detection of Arctic char’s environmental DNA (eDNA) in an
 indoor mesocosm as well as in natural habitats (six lakes). Specifically,
 the mesocosm experiment revealed that sample volume can have significant
 effects on the application of eDNA approaches, whereby probability of
 detection depends from proximity to the source organism as well as volume
 of water filtered. When tested in the wild, positive amplification of
 Arctic char eDNA was observed in four of the six lakes sampled, proving
 that this approach can be successfully implemented in natural conditions.
 However, findings from the present study also showed that sub-optimal
 sampling strategies can lead to false negative results (e.g. failure to
 detect the species when it is present). This study corroborates findings
 from other research on eDNA detection of fish species, showing that
 despite its current limitations this approach can be a fast, non-invasive
 and effective tool in aid to the conservation and management of freshwater
 fish species.
