title: Post-fire vegetation succession in the Siberian subarctic tundra over 45 years

description: Wildfires are relatively rare in subarctic tundra ecosystems, but they can
 strongly change ecosystem properties. Short-term fire effects on subarctic
 tundra vegetation are well documented, but long-term vegetation recovery
 has been studied less. The frequency of tundra fires will increase with
 climate warming. Understanding the long-term effects of fire is necessary
 to predict future ecosystem changes. We used a space-for-time approach to
 assess vegetation recovery after fire over more than four decades. We
 studied soil and vegetation patterns on three large fire scars
 (&gt;44, 28 and 12 years old) in dry, lichen-dominated forest tundra
 in Western Siberia. On 60 plots, we determined soil temperature and
 permafrost thaw depth, sampled vegetation and measured plant functional
 traits. We assessed trends in NDVI to support the field-based results on
 vegetation recovery.Soil temperature, permafrost thaw depth and total
 vegetation cover had recovered to pre-fire levels after &gt;44 years,
 as well as total vegetation cover. In contrast, after &gt;44 years,
 functional groups had not recovered to the pre-fire state. Burnt areas had
 lower lichen and higher bryophyte and shrub cover. The dominating shrub
 species, Betula nana, exhibited a higher vitality (higher specific leaf
 area and plant height) on burnt compared with control plots, suggesting a
 fire legacy effect in shrub growth. Our results confirm patterns of shrub
 encroachment after fire that were detected before in other parts of the
 Arctic and Subarctic. In the so far poorly studied Western Siberian forest
 tundra we demonstrate for the first time, long-term fire-legacies on the
 functional composition of relatively dry shrub- and lichen-dominated
 vegetation.

title: Allometry rather than abiotic drivers explains biomass allocation among leaves, stems and roots of Artemisia across a large environmental gradient in China

description: 1. Biomass allocation patterns reflect the adaptive strategies of plants
 growing in different environments, which is a central issue in comparative
 plant ecology and evolution. However, the factors underpinning specific
 allocation patterns across organs and the existence of general rules
 governing allocation remain contentious. Optimal partitioning theory (OPT)
 states that plants can respond to resource availability by allocating
 relatively more biomass to the organ that captures the most limiting
 resources to optimize growth. In contrast, allometric partitioning theory
 (APT) postulates that biomass allocation among organs is a power function
 of plant size independently of environmental variation. As phylogenetic
 and growth form constraints (e.g. formation of inert heartwood in tree
 clades) may also affect biomass allocation, comparison among and within
 closely related taxa of rather similar growth form may enable a more
 direct testing of which of these two theories prevails. 2. To test whether
 OPT or APT was prevalent at wide geographic scale, we investigated biomass
 allocation patterns among leaves, stems and roots of 1022 plants of 63
 Artemisia species (Asteraceae) collected along broad climate (annual mean
 temperature range -4.9 to 18.0 °C, annual mean precipitation range 193 to
 1668 mm) and soil gradients (soil carbon content range 1.6 to 15.4 kg C
 m-2) in central and eastern China. 3. There were strong allometric
 relationships among leaf mass (ML), stem mass (MS) and root mass (MR) at
 both inter- and intraspecific level. Moreover, the interspecific and
 intraspecific patterns were not different from general patterns for pooled
 plants, i.e. ML/MR and ML/MS, but not MS/MR, generally decreased with
 plant size. However, the three organ mass ratios were not responsive to
 broad climatic or soil gradients after the effect of plant size was
 removed. 4. Synthesis. Our results generally support APT instead of OPT,
 suggesting that Artemisia plants have evolved an allometric strategy
 rather than relying on adjustment of allocation among organs to adapt to
 the broadly varying environments at the regional scale. For follow-up
 research, we hypothesize that the strong allometric constraints on biomass
 allocation should depend on strong physiological adaptive responses of the
 different organs of Artemisia to environmental gradients.

title: Data from: Ecological and evolutionary responses of an arctic plant to variation in microclimate and soil

description: The arctic and alpine regions are predicted to experience some of the
 highest rates of climate change, and the arctic vegetation is expected to
 be especially sensitive to such changes. Understanding the ecological and
 evolutionary responses of arctic plant species to changes in climate is
 therefore a key objective. Geothermal areas, where natural temperature
 gradients occur over small spatial scales, and without many of the
 confounding environmental factors present in latitudinal and other
 gradient studies, provide a natural experimental setting in which to
 examine the response of arctic-alpine plants to increasing temperatures.
 To test the ecological and evolutionary response of the circumpolar alpine
 bistort (Persicaria vivipara) to temperature, we collected plant material
 and soil from areas with low, intermediate, and high soil temperatures and
 grew them at three different temperatures in a threefactorial growth
 chamber experiment. At higher experimental soil temperatures, sprouting
 was earlier, and plants had more leaves. Sprouting was earlier in soil
 originating from intermediate temperature and plants had more leaves when
 grown in soil originating from low temperatures. We did not find evidence
 of local adaptation or genetic variation in reaction norms among plants
 originating from areas with low, intermediate, and high soil temperature.
 Our findings suggest that the alpine bistort has a strong plastic response
 to warming, but that differences in soil temperature have not resulted in
 genetic differentiation. The lack of an observed evolutionary response
 may, for example, be due to the absence of temperature-mediated selection
 on P. vivipara, the low rate of sexual recombination, or high levels of
 gene flow balancing differences in selection. When placed within the
 context of other studies, we conclude that arctic-alpine plant species
 often show strong plastic responses to spring warming, while evidence of
 evolutionary responses varies among species.

title: Optimized culture systems for the preimplatation ICR mouse embryos with wide range of EDTA concentrations

description: In this study, in vitro preimplantation embryo culture media especially
 for outbred stock mice (Institute of Cancer Research (ICR)) were optimized
 with different concentrations of Ethylenediaminetetraacetic acid (EDTA). A
 plot with embryo development rates against EDTA concentrations ranging
 from 0 to 500µM showed a unique pattern with two characteristic peaks.
 200µM was adopted as an optimal concentration of EDTA. The optimized media
 were also evaluated with two culture systems; conventional large volume
 culture system (1ml) and micro-droplet culture system. In the conventional
 large volume culture system, the blastocyst development rates were
 compared among three different media (F-10, KSOM and KSOM with the
 optimized 200µM EDTA). The rates were 0.4%, 16.7% and 57.6%, respectively.
 The development rates for micro-droplet (10µl) culture system was 73.9%.
 In conclusion, 200µM EDTA concentration in 10µl droplets in the KSOM
 medium was found as most suitable culture conditions for ICR mouse embryos
 as the blastocyst development rate was higher in micro-droplet culture
 system than in the traditional conventional large volume culture
 system.

title: Data from: Sex-specific effects of experimental ectoparasite infestation on telomere length in great tit nestlings

description: Telomere length is a biomarker of biological ageing and lifespan in
 various vertebrate taxa. Evidence is accumulating that telomeres shorten
 more rapidly when an individual is exposed to environmental stressors.
 Parasites are potent selective agents that can cause physiological stress
 directly or indirectly through the activation of the host’s immune system.
 Yet to date, empirical evidence for a role of parasites in telomere
 dynamics in natural populations is limited. Here we show experimentally
 that exposure to ectoparasitic hen fleas (Ceratophyllus gallinae) during
 growth results in shorter telomeres in female, but not male, great tit
 (Parus major) nestlings. Females had significantly longer telomeres than
 males when growing up in experimentally deparasitized nests but because of
 the sex-specific effects of parasitism on telomere length, this sexual
 dimorphism was absent in birds growing up in experimentally infested
 nests. Our results provide the first experimental evidence for a role of
 ectoparasitism in telomere dynamics in a natural vertebrate population,
 and suggest that the costs of infection manifest in sex-specific ways.

title: Sex-specific sterility caused by extreme temperatures is likely to create cryptic changes to the operational sex ratio in Drosophila virilis

description: Climate change is increasing the frequency and severity of short-term heat
 shocks that threaten the persistence of natural populations. The effect of
 thermal stress on natural selection is a common topic of debate, but high
 temperatures can also influence sexual selection. Typically, males and
 females of a species can survive at similar extreme temperatures, but
 males have been shown to lose fertility at lower temperatures than
 females. Here, we examine how a brief exposure of pupae to high
 temperatures in the fruit fly Drosophila virilis affects adult fertility
 in both males and females. We find strong sexual dimorphism in
 temperature-induced sterility. This has the potential to quickly and
 unpredictably create populations composed of mostly sterile males and
 fertile females, resulting in changes to the operational sex ratio (OSR).
 These disruptions are likely to be cryptic and difficult to measure in the
 wild, especially considering that males can eventually recover fertility
 and that sterile males of some species can still copulate. Changes to the
 OSR in this way are likely to influence sexual selection by favouring
 females that can discriminate between fertile and sterilised males, and
 possibly leading to female-female conflict over a limited pool of fertile
 males. Further research on how cryptic disruptions to the OSR affect
 sexual selection dynamics is critical for understanding the impact of
 environmental change on biodiversity.

title: Microsatellite data of 14 Avicennia marina populations from Mozambique Channel area

description: Mangrove forests are dynamic ecosystems found along sheltered low-lying
 coastal plains in warm-temperate, tropical and subtropical regions,
 predominantly on tidal flats, deltas, estuaries, bays, but also on oceanic
 atolls. These landforms present varied hydrodynamic and geomorphological
 settings for mangroves to establish and could influence the extent of
 propagule transport and subsequent regeneration. In this study, we
 examined whether these landform characteristics influence the genetic
 diversity and structure of Avicennia marina, one of the most abundant and
 widespread mangrove species. To do so, we considered 14 populations
 located in estuarine and coastal bay environments spread across the
 Western Indian Ocean region. A transect approach was considered to
 estimate kinship-based fine-scale spatial genetic structure using fifteen
 polymorphic microsatellite markers in 475 adult A. marina trees from 14
 different populations. No overall significant difference was found in the
 levels of allele or gene diversities between coastal bay and estuarine
 populations. However, some South African estuarine populations showed
 strong inbreeding levels that are most likely due to the recurrent closing
 of the river mouth, lowering the chance of external propagule input.
 Elevated kinship values and significant fine-scale spatial genetic
 structure up to 30 m, 60 m or 90 m distance were detected in all coastal
 bays, indicating a topographic setting suitable for propagule retention
 and establishment within a neighborhood. Slopes of a linear regression
 over restricted distance within 150 m were significantly declining in each
 sheltered transect. Contrastingly, such a spatial structure could not be
 detected for transects along the rivers of the estuarine systems
 considered, suggesting that recruitment here is governed by unrelated
 carried-away mixed-origin propagules. In general, we have shown that A.
 marina populations can locally experience different modes of propagule
 movement, explained from their position in estuaries. Thus, the resilience
 and natural regeneration of mangroves is achieved by different mechanisms
 for settings with different hydrodynamic conditions, which can be
 important information for their management and protection within the
 variety of coastal environments.

title: Data analysis from: Demographic consequences of changing body size in a terrestrial salamander

description: Changes in climate can alter individual body size, and the resulting
 shifts in reproduction and survival are expected to impact population
 dynamics and viability. However, appropriate methods to account for
 size-dependent demographic changes are needed, especially in understudied
 yet threatened groups such as amphibians. We investigated individual and
 population-level demographic effects of changes in body size for a
 terrestrial salamander using capture-mark-recapture data. For our
 analysis, we implemented an integral projection model parameterized with
 capture-recapture likelihood estimates from a Bayesian framework. Our
 study combines survival and growth data from a single dataset to quantify
 the influence of size on survival while including different sources of
 uncertainty around these parameters, demonstrating how selective forces
 can be studied in populations with limited data and incomplete recaptures.
 We found a strong dependency of the population growth rate on changes in
 individual size, mediated by potential changes in selection on mean body
 size and on maximum body size. Our approach of simultaneous parameter
 estimation can be extended across taxa to identify eco-evolutionary
 mechanisms acting on size-specific vital rates, and thus shaping
 population dynamics and viability.

title: Phylogenomic data for hyperdiverse daisy tribes

description: Asteraceae account for 10% of all flowering plant species, and 35-40% of
 these are in five closely-related tribes that total over 10,000 species.
 These tribes include Anthemideae, Astereae, Calenduleae, Gnaphalieae, and
 Senecioneae, which form one of two enormous clades within Subfamily
 Asteroideae. We took a phylogenomics approach to resolve evolutionary
 relationships among these five tribes. We sampled the nuclear and plastid
 genomes via HybSeq target enrichment and genome skimming, and recovered 74
 plastid genes and nearly 1000 nuclear loci, known as Conserved Orthologous
 Sequences. We tested for conflicting support in both datasets and used
 network analyses to assess patterns of reticulation to explain the early
 evolutionary history of this lineage which has experienced whole genome
 duplications and rapid radiations. We found both concordance and
 conflicting support in both datasets and documented four ancient
 hybridization events. Due to the timing of the early radiation of this
 five-tribe lineage, shortly before the Eocene-Oligocene extinction event
 (34 MYA), early lineages were likely lost, obscuring some details of their
 early evolutionary history.

title: Peeling back the layers: First phylogenomic insights into the Ledebouriinae (Scilloideae, Asparagaceae)

description: The Ledebouriinae (Scilloideae, Asparagaceae) are a widespread group of
 bulbous geophytes found predominantly throughout seasonal climates in
 sub-Saharan Africa, with a handful of taxa in Madagascar, the Middle East,
 India, and Sri Lanka. Phylogenetic relationships within the groups have
 been historically difficult to elucidate. Here, we provide the first
 phylogenomic perspective into the Ledebouriinae. Using the Angiosperms353
 targeted enrichment probe set, we consistently recovered four major clades
 (i.e., two Ledebouria clades, Drimiopsis, and Resnova). The two Ledebouria
 clades closely align with geography, either consisting almost entirely of
 sub-Saharan African taxa (Ledebouria Clade A), or East African and
 non-African taxa (Ledebouria Clade B). Our results suggest that the
 Ledebouriinae likely underwent a rapid radiation leading to rampant
 incomplete lineage sorting. We additionally find evidence for potential
 historical hybridization between Drimiopsis and a subclade within
 Ledebouria Clade A.

title: Extinction of herbivorous dinosaurs linked to Early Jurassic global warming event

description: Sauropods, the giant long-necked dinosaurs, became the dominant group of
 large herbivores in terrestrial ecosystems after multiple related lineages
 became extinct towards the end of the Early Jurassic (190–174 Ma). The
 causes and precise timing of this key faunal change and as well as the
 origin of eusauropods (true sauropods) have remained ambiguous mainly due
 to the scarce dinosaurian fossil record of this time. The Cañadón Asfalto
 basin in Patagonia (Argentina) contains terrestrial sequences that
 document this critical interval of dinosaur evolution. Here we report a
 new dinosaur from this basin that is the oldest eusauropod known with a
 nearly complete skull and provide precise U-Pb radioisotopic dates that
 time the rise of eusauropods in Patagonia. We show eusauropod-dominance
 was established after a massive magmatic event impacting southern Gondwana
 (180–184 Ma) and coincided with severe perturbations to the climate and a
 drastic decrease in the floral diversity characterized by the rise of
 conifers with small scaly leaves. Floral and faunal changes from other
 regions suggest these were global changes that affected terrestrial
 ecosystems during the Toarcian warming of climate and formed part of a
 second-order mass extinction event.

title: Filtered SNPs for wild Paspalum vaginatum and Paspalum distichum

description: Filtered SNP calls in .ped format from "Hybridization, polyploidy and
 clonality influence geographic patterns of diversity and salt tolerance in
 the model halophyte seashore paspalum (Paspalum vaginatum)". We used
 GBS to genotype 218 P. vaginatum and P. distichum accessions collected
 from the US Gulf and Atlantic coasts plus available USDA germplasm. We
 confirm that P. vaginatum and P. distichum are genetically distinct and
 that the coarse-textured ecotype of P. vaginatum is composed of hybrids
 between fine-textured accessions and an unidentified paspalum species.
 These hybrids vary in ploidy and subgenome composition which may influence
 their geographic patterns of adaptation to saline environments.
description: Read processing and variant calling were performed using the
 Fast-GBS pipeline with default parameters (Torkamaneh, Laroche, Bastien,
 Abed, & Belzile, 2017), which demultiplexes with sabre v1.000
 (Joshi, 2011), trims with cutadapt v1.14 (Martin, 2011), maps with BWA MEM
 v0.7.12-r1039 (Li & Durbin, 2009) and calls variants with Platypus
 v0.8.1 (Rimmer et al., 2014). This produced a large SNP dataset which was
 then further filtered with plink v1.90b4.6<i> </i>(Purcell et
 al. 2007). Sites were removed if there were missing calls for more than
 10% of the samples or had less than 0.01 minor allele frequency.
 Individuals that were missing calls at 50% or more sites were also
 removed.
