title: Synthesis of a novel amphoteric copolymer and its application as a dispersant for coal water slurry preparation

description: In this work, a novel amphoteric copolymer was synthesized via free
 radical polymerization, named Poly(sodium p-styrenesulfonate–co-acrylic
 acid-co-diallyldimethylammonium chloride) (P(SS-co-AA-co-DMDAAC)).
 Afterwards, P(SS-co-AA-co-DMDAAC) was explored for use as a dispersant in
 coal water slurry (CWS) preparation. The structure of
 P(SS-co-AA-co-DMDAAC) was verified by Fourier transform infrared
 spectroscopy (FTIR) and Nuclear magnetic resonance (NMR). The synthetic
 conditions were optimized as the feed ratio of AA to SS was 1:1 (for Yulin
 coal) or 1.5:1 (for Yili coal), and DMDAAC dosage was 4.0 wt% (for Yulin
 coal) and 6.0 wt% (for Yili coal) toward total monomers. The performances
 of P(SS-co-AA-co-DMDAAC) as a dispersant for CWS were evaluated by various
 technologies, such as apparent viscosity, Zeta potential, static stability
 and contact angle measurements. The results revealed that the optimized
 dosage of P(SS-co-AA-co-DMDAAC) in CWS preparation was 0.3 wt% and 0.4 wt%
 for Yulin coal and Yili coal respectively. In this optimum condition, CWS
 prepared using P(SS-co-AA-co-DMDAAC) as dispersant showed a typical shear
 thinning behavior and excellent stability, which are desired in industry.
 The rheological models also confirmed the pseudo-plastic characteristics
 of CWS. Finally, as compared to the widespread used anionic dispersant
 Poly(sodium p-styrenesulfonate) (PSS), P(SS-co-AA-co-DMDAAC) developed in
 this work exhibited better slurry making performance. Introduction of
 cationic functional groups promoted the adsorption of dispersant, which
 further enhanced the electrostatic repulsion among coal particles.
 Accordingly, the viscosity of CWS decreased and static stability enhanced.

title: Effects of different moose browsing pressures on the succession of plant communities within the herbaceous and saplings layers of a boreal forest

description: The present data is constituted of four different excel files: browsing
 data, herbs layer data, saplings layer data and latin names data. 1)
 Browsing data contains the number of browsed and unbrowsed twigs from all
 ligneous plants in the samplings plots along time. 2) Herbs layer data
 contains the cumulated cover of all plants species along 14 three meters
 long and one meter high transcects within each experimental units. 3)
 Saplings layer data contains the number of saplings from each species
 within each experimental units (280 m2). 4) Latin names data contains the
 latin names corresponding to the different species codes found within the
 herbs and saplings data. All data sets contain his metadata sheet.
description: To analyze the impact of different moose browsing pressures on
 forest succession, we used an experimental design of 15 pairs of fenced
 and unfenced experimental units (28.5 m X 14 m, for 400 m² each)
 distributed along a gradient of moose density. We measured the linear
 interception of herbaceous, shurbs and trees species along 14 three meters
 long and one meter high transects within each experimental unit. We
 tallied the ground layer cover in July from the second year following
 fencing (T2) to 2016, with the exception of 2015. We counted the stems of
 every ligneous species reaching breast height (1.3 m) over the complete
 area of each experimental unit, minus a 1.5 m-buffer along fences. We
 conducted this inventory yearly from 2010 to 2016. A posteriori, we
 categorized <i>Picea mariana</i> and <i>Picea
 glauca</i> under <i>Picea spp</i>., <i>Betula
 papyrifera</i> and <i>Betula alleghaniensis</i> under
 <i>Betula spp.</i>, all sedges under <i>Carex
 spp.</i> and all grasses under <i>Grass spp</i>. To
 evaluate moose browsing pressure, we tallied browse availability in twelve
 circular 4 m<sup>2</sup> plots systematically distributed
 within each experimental unit. In each plot, we identified all ligneous
 species and counted the total number of twigs ≥ 10 cm long and the number
 of browsed twigs for every stem within 10 and 300 cm, except white and
 black spruces.

title: Unmasking viral sequences by metagenomic next-generation sequencing in adult human blood samples during steroid-refractory/dependent graft-versus-host disease

description: Background: Viral infections are common complications following allogeneic
 hematopoietic stem cell transplantation (allo-HSCT). Allo-HSCT recipients
 with steroid-refractory/dependent graft-versus-host disease (GvHD) are
 highly immunosuppressed and are more vulnerable to infections with weakly
 pathogenic or commensal viruses. Here, twenty-five adult allo-HSCT
 recipients from 2016 to 2019 with acute or chronic
 steroid-refractory/dependent GvHD were enrolled in a prospective cohort of
 patients at Geneva University Hospitals. We performed metagenomics
 next-generation sequencing (mNGS) analysis using a validated viral
 pipeline and de novo analysis on pooled stored routine plasma samples
 collected throughout the period of intensive steroid treatment or
 second-line GvHD therapy to identify weakly pathogenic, commensal and
 unexpected viruses. Results: Median duration of intensive
 immunosuppression was 5.1 months (IQR 5.5). GvHD-related mortality rate
 was 36%. mNGS analysis detected viral nucleotide sequences in 24/25
 patients. Sequences of ≥3 distinct viruses were detected in 16/25
 patients, Anelloviridae (24/25) and human pegivirus-1 (9/25) were the most
 prevalent. In 7/25 patients with fatal outcomes, unexpected viral
 sequences, not assessed by routine investigations, were identified with
 mNGS and confirmed by RT-PCR. These cases included usutu virus (1),
 rubella virus (1 vaccine-strain and 1 wild-type), novel human astrovirus
 (HAstV) MLB2 (1), classic HAstV (1), human polyomavirus 6 and 7 (2),
 cutavirus (1), and bufavirus (1). Conclusions: Unexpected, opportunistic
 and protracted viral infections were identified in 28% of highly
 immunocompromised allo-HSCT recipients with steroid refractory/dependent
 GvHD. These identified viruses have all been previously described in
 humans, but have poorly understood clinical significance. Rubella virus
 identification raises the possibility of re-emergence from past infections
 or vaccinations.

title: Context-dependent reproductive isolation: host plant variability drives fitness of hybrid herbivores

description: The role of divergent selection between alternative environments is
 well-recognized to promote reproductive isolation (RI) between lineages.
 However, most studies view each divergent environment as homogenous,
 thereby overlooking the potential role of within environment variation on
 RI between differentiating lineages. Here we test the importance of
 microenvironmental variation on RI using individual trees of two host
 plants each harboring locally adapted populations of the cynipid wasp,
 Belonocnema treatae.  We compared the fitness surrogate
 (survival) of offspring from hybrid crosses with residents across
 individuals of each  host plant Quercus virginiana and Q.
 geminata. We found evidence of weak hybrid inviability between
 host-associated lineages of B. treatae despite strong genomic
 differentiation. However, averaging across environments, masked great
 variation in hybrid fitness on individual trees, where hybrids performed
 worse than, equal to, or better than residents. Considering the
 environmental context of hybridization is thus critical to improving the
 predictability of divergence under variable selection.

title: Estimating the Net Value of Treating Hepatitis C Virus Using Newly Available Direct-Acting Antivirals in India (Supporting Datasets)

description: Recently developed direct-acting antiviral (DAA) treatments for hepatitis
 C virus (HCV) have been groundbreaking for their high efficacy across
 disease genotypes and lack of severe side effects. This study uses a
 cost-of-illness (COI) approach to estimate the net value conferred by this
 class of drugs using the cost and efficacy of one of these novel drug
 combinations, sofosbuvir and velpatasvir (SOF/VEL), recently licensed for
 generic manufacture in India. This study considers COI of lifetime
 earnings lost by patients and potential secondarily infected individuals
 due to disability and premature death from HCV infection. Expected net
 benefits of treatment are substantial for non-cirrhotic (NC) and
 compensated cirrhotic (CC) patients (ranging from 5,98,003 INR for NC
 women to 1,05,25,504 INR for CC men). Increased earnings are not
 sufficient to fully offset cost of treatment for decompensated cirrhotic
 individuals but treatment may still be justified on the basis of the
 intrinsic value of health improvements and other treatment benefits.

title: Phylogenomics, biogeography and taxonomic revision of New Guinean pythons (Pythonidae, Leiopython) harvested for international trade

description: The large and enigmatic New Guinean pythons in the
 genus Leiopython are harvested from the wild to supply
 the international trade in pets. Six species are currently recognized
 (albertisii, biakensis, fredparkeri, huonensis, meridionalis, montanus) but the taxonomy of this group has been controversial. We combined analysis of 421 nuclear loci and complete mitochondrial genomes with morphological data to construct a detailed phylogeny of this group, understand their biogeographic patterns and establish the systematic diversity of this genus. Our molecular genetic data support two major clades, corresponding to L. albertisii and L. meridionalis, but offer no support for the other four species. Our morphological data also only support two species. We therefore recognize L. albertisii and L. meridionalis as valid species and place L. biakensis, L. fredparkeri, L. huonensis and L. montanus into synonymy. We found that L. albertisiiand L. meridionalis are sympatric in western New Guinea; an atypical pattern compared to other Papuan species complexes in which the distributions of sister taxa are partitioned to the north and south of the island’s central mountain range. For the purpose of conservation management, overestimation of species diversity within Leiopython has resulted in the unnecessary allocation of resources that could have been expended elsewhere. We strongly caution against revising the taxonomy of geographically widespread species groups when little or no molecular genetic data and only small morphological samples are available.

title: Heatwave effects on the behavior and life history traits of sedentary antlions

description: Research on the behavioral responses of animals to extreme weather events,
 such as heatwaves, is lacking even though their frequency and intensity in
 nature are increasing. Here, we investigated the behavioral response to a
 simulated heatwave in two species of antlions (Neuroptera:
 Myrmeleontidae). These insects spend the majority of their lives as larvae
 and live in sandy areas suitable for a trap-building hunting strategy. We
 used larvae of Myrmeleon bore and Euroleon nostras, which are
 characterized by different microhabitat preferences – sunlit in the case
 of M. bore and shaded in the case of E. nostras. Larvae were exposed to
 fluctuating temperatures (40ºC for 10 hours daily and 25ºC for the
 remaining time) or a constant temperature (25ºC) for an entire week. We
 found increased mortality of larvae under heat. We detected a reduction in
 the hunting activity of larvae under heat, which corresponded to changes
 in the body mass of individuals. Furthermore, we found long-term
 consequences of the simulated heatwave, as it prolonged the time larvae
 needed to molt. These effects were pronounced in the case of E. nostras
 but did not occur or were less pronounced in the case of M. bore,
 suggesting that microhabitat-specific selective pressures dictate how well
 antlions handle heatwaves. We thus present results demonstrating the
 connection between behavior and the subsequent changes to fitness-relevant
 traits in the context of a simulated heatwave. These results illustrate
 how even closely related species may react differently to the same event.

title: Data from: The legacy of Eastern Mediterranean mountain uplifts – rapid disparity of phylogenetic niche conservatism and divergence in mountain vipers

description: Aim The orogeny of the eastern Mediterranean region has substantially
 affected ecological speciation patterns, particularly of mountain-dwelling
 species. Mountain vipers of the genus Montivipera are among the paramount
 examples of Mediterranean neo-endemism, with restricted ranges in the
 mountains of Anatolia, the Levant, Caucasus, Alborz, and Zagros. Here we
 explore the phylogenetic and ecological diversification of Montivipera to
 reconstruct its ecological niche evolution and biogeographic history.
 Location Eastern Mediterranean mountain ecosystems Methods Using 177
 sequences of three mitochondrial genes, a dated molecular phylogeny of
 mountain vipers was reconstructed. Based on 320 occurrence points within
 the entire range of the genus and six climatic variables, ecological
 niches were modelled and used to infer ancestral niche occupancy. In
 addition, the biogeographic history and ancestral states of the species
 were reconstructed across climate gradients. Results Dated phylogenetic
 reconstruction revealed that the ancestor of mountain vipers split into
 two major clades at around 12.18 Mya followed by multiple vicariance
 events due to rapid orogeny. Montivipera colonised coastal regions from a
 mountain-dwelling ancestor. We detected a highly complex ecological niche
 evolution of mountain vipers to temperature seasonality measured by means
 of a strong phylogenetic signal. Conclusion Raising mountain belts in the
 Eastern Mediterranean region and subsequent remarkable changes in
 temperature seasonality have led to the formation of important centres of
 diversification and endemism in this biodiversity hotspot. High rates of
 niche conservatism, low genetic diversity, and segregation of ranges into
 the endemic distribution negatively influenced the adaptive capacity of
 mountain vipers. We suggest that these species should be considered as
 evolutionary significant units and priority species for conservation in
 Mediterranean mountain ecosystems.

title: Mobilisation of data to stakeholder communities: Bridging the research-practice gap using a commercial shellfish species model

description: Knowledge mobilisation is required to “bridge the gap” between research,
 policy and practice. This activity is dependent on the amount, richness
 and quality of the data published. To understand the impact of a changing
 climate on commercial species, stakeholder communities require better
 knowledge of their past and current situations. The common cockle
 (Cerastoderma edule) is an excellent model species for this type of
 analysis, as it is well-studied due to its cultural, commercial and
 ecological significance in west Europe. Recently, C. edule harvests have
 decreased, coinciding with frequent mass mortalities, due to factors such
 as a changing climate and diseases. In this study, macro and micro level
 marine historical ecology techniques were used to create datasets on
 topics including: cockle abundance, spawning duration and harvest levels,
 as well as the ecological factors impacting those cockle populations.
 These data were correlated with changing climate and the Atlantic
 Multidecadal Oscillation (AMO) index to assess if they are drivers of
 cockle abundance and harvesting. The analyses identified the key
 stakeholder communities involved in cockle research and data acquisition.
 It highlighted that data collection was sporadic and lacking in
 cross-national/stakeholder community coordination. A major finding was
 that local variability in cockle populations is influenced by biotic
 (parasites) and abiotic (temperature, legislation and harvesting) factors,
 and at a global scale by climate (AMO Index). This comprehensive study
 provided an insight into the European cockle fishery but also highlights
 the need to identify the type of data required, the importance of
 standardised monitoring, and dissemination efforts, taking into account
 the knowledge, source, and audience. These factors are key elements that
 will be highly beneficial not only to the cockle stakeholder communities
 but to other commercial species.

title: Data: Generalized evidence for Bergmann’s rule body size variation in a cosmopolitan owl genus

description: Aim: The eco-geographic Bergmann’s rule predicts that animals
 have smaller body size in warmer regions than in cold environments because
 of thermoregulatory reasons. Although this rule has been widely
 investigated, intraspecific analyses on cosmopolitan taxa are rare. We
 examined whether geographic variation in wing length, a proxy of body
 size, shows a Bergmannian pattern and can be explained by three mechanisms
 known to affect animal body size (heat conservation, resource availability
 and starvation resistance) in seven species of nocturnal raptors of the
 genus Tyto. Location: World. Taxon: Genus Tyto.
 Methods: We measured wing length of 9033 museum
 specimens covering the entire distributional range of each species and
 linked it with geographic (absolute latitude, elevation) and climatic
 predictors associated with heat conservation, resource availability and
 starvation resistance hypotheses of spatial variation in body size.
 Results: All the species show a trend of increasing wing length
 with increasing latitude and/or elevation, and in five of them either or
 both geographic predictors are statistically significant. In all the
 species showing a Bergmannian pattern, wing length significantly decreases
 with temperature, thus supporting the heat conservation hypothesis.
 Conversely, we found less generalized support for the other hypotheses,
 although in some species significant trends between wing length and
 proxies of climatic seasonality and/or primary productivity emerged. Main
 conclusions: Consistent clines in body shrinking in warm
 environments are observed in species living in different continents at
 different latitudinal and temperature ranges, as well as exploiting
 different habitats. These findings thus support the hypothesis that body
 size is, at least partly, selected for heat maintenance depending on the
 thermal environment, even in nocturnal species which are not directly
 exposed to solar radiation. However, different selective pressures may
 also have concomitantly acted to promote body size evolution in this bird
 group.

title: Repeatable individual variation in migration timing in two anadromous salmonids and ecological consequences

description: Consistent individual differences in behaviour has been demonstrated for
 many animals, but there are few studies of consequences of such repeated
 behaviour in the wild. We tested consistency in migration timing to and
 from the sea among anadromous Arctic char (Salvelinus alpinus) and brown
 trout (Salmo trutta), using data from a study period of about 25 years,
 including more than 27,000 uniquely Carlin-tagged individuals that
 migrated to sea for feeding in the spring and returned to the river in
 late summer for up to 13 successive years. Consistency was found between
 individuals across time in timing of the seaward migration. Individuals
 migrating early during their first migration tended to migrate early the
 following years, and late migrants tended to migrate late. The same
 pattern was found also at ascent to freshwater. Hence, this study
 demonstrated that individual fish in nature can differ in behaviour
 related to migration timing, and that these differences can be consistent
 during their life time. Early migrants increased their mass more than late
 migrants, and had a higher specific growth rate. Early migrating Arctic
 char, but not brown trout, experienced a longer life after the first
 migration to sea than late migrants. In both species, maturity occurred
 earlier in individuals that migrated early. For brown trout, but not for
 Arctic char, fecundity was significantly correlated to the timing of smolt
 migration. Hence, the repeatable individual variation in migration timing
 seemed to have ecological and fitness consequences in terms of growth,
 longevity, timing of maturity, and life-time fecundity.
description: During 1987–2012, Arctic char and brown trout were sampled via
 permanent fish traps installed across the river 200 m upstream from the
 sea. All fish larger than 10 cm were trapped with a Wolf trap (apertures
 10 mm, inclination 1:10) for descending fish and a fixed box trap for
 ascending fish. The traps were operated during the ice-free period (April
 through October) and were emptied twice per day (at 0800 and 2000 h). Body
 length (<i>L</i> in mm, measured as total length of the fish
 with the tail fin in its natural position) and mass (<i>M</i>,
 in g) were recorded for all fish. Smolts of brown trout and Arctic char
 &gt; 18 cm were tagged with individually numbered Carlin tags. These
 individuals were recorded each time they passed the fish traps during
 their annual migration to sea and back to the river for the rest of their
 lives.
