title: Data from: Monadelpha (Euphorbiaceae, Plukenetieae), a new genus of Tragiinae from the Amazon rainforest of Venezuela and Brazil

description: Monadelpha L.J.Gillespie & Card.-McTeag., gen.
 nov., is described as a new member of Euphorbiaceae tribe
 Plukenetieae subtribe Tragiinae, to accommodate Tragia
 guayanensis, a species known from western Amazonas, Venezuela and, newly
 reported here, from Amazonas, Brazil.  The genus is
 unique in the subtribe for having 5-colpate pollen and staminate flowers
 with filaments entirely connate into an elongate, cylindrical staminal
 column terminated by a tight cluster of
 anthers.  Phylogenetic analyses based on nuclear rDNA
 ITS and sampling 156 accessions across the diversity of Tragiinae (all 12
 genera and 77 of ~195 species) also
 support Monadelpha as a distinct lineage that is
 separate from Tragia.  A revised key to the
 genera of Tragiinae in South America and Central America is provided.

title: Robust vestibular self-motion signals in macaque posterior cingulate region

description: Self-motion signals, distributed ubiquitously across parietal-temporal
 lobes, propagate to limbic hippocampal system for vector-based navigation
 via hubs including posterior cingulate cortex (PCC) and retrosplenial
 cortex (RSC). Although numerous studies have indicated that posterior
 cingulate areas are involved in spatial tasks, it is unclear about how
 their neurons represent self-motion signals. By providing translation and
 rotation stimuli to macaques on a 6-degree-of-freedom motion platform, we
 discovered robust vestibular responses in PCC. A combined 3-dimensional
 spatiotemporal model captured data well and revealed multiple temporal
 components including velocity, acceleration, jerk, and position. The
 former three signals, but not position, conveyed consistent spatial
 information. Compared to PCC, RSC contained moderate vestibular temporal
 modulations and lacked significant spatial tuning. Visual self-motion
 signals were much weaker in both regions compared to the vestibular
 signals. We conclude that macaque posterior cingulate region carries
 vestibular-dominant self-motion signals with plentiful temporal components
 that could be useful for path integration.

title: 1998-2017 Belt and Road Initiative countries Fragile States Index and global terrorism attack events

description: (1)During 1998–2017, the number of events was the highest on Mondays and
 the lowest on Fridays. In addition, the incidence of events was high
 between Monday and Thursday but the lowest on Fridays and Saturdays.
 Meanwhile, the number of events was the largest in January, May, July, and
 November, and the lowest in June and September; the incidence of terrorist
 attacks in April to May and July to August is high. (2) Terrorist attacks
 showed a 10-year cycle during the study period. Terrorist attacks in the
 last 10 years of the study period were broader in scope and higher in
 number compared to the previous 10 years. In addition, China, Russia,
 Saudi Arabia, and northeastern Europe saw many new terrorist attacks
 during the latter 10 years. (3) The number of terrorist attacks by
 bombing/explosion was the largest, followed by armed attack;
 assassination, kidnapping, and infrastructure attacks were the least
 frequent. The core areas of the terrorist attacks were Iraq, Israel,
 Afghanistan, Pakistan, and India.  (4) The driving force analysis
 revealed that the indicators “security apparatus,” “human flight and brain
 drain,” and “external intervention” contributed the most to BRI terrorist
 attacks.

title: Chrysaora quinquecirrha high-continuity genome annotation data

description: The Atlantic sea nettle (Chrysaora quinquecirrha) has a key evolutionary
 position due to its high ecological value. However, the published
 C.quinquecirrhagenome assembly is very fragmented, due to limited
 sequencing technologies and the complicated jellyfish genomic sequence.
 Here, we used the most advanced high-through chromosome conformation
 capture technology to get high-coverage sequencing data of the
 C.quinquecirrha genome. Then we anchored these data to the previously
 published contig-level genome assembly to improve its genome. Finally, a
 high-continuity genome sequence of C.quinquecirrha was successfully
 assembled, which contained 1,882scaffoldswith a N50 length of 3.83 Mb. The
 N50 length of this version of the genome assembly is 5.23 times longer
 than the previously released one, and additional analysis revealed that it
 has a high degree of genomic continuity and accuracy. Acquisition of the
 high-continuity genome sequence of C.quinquecirrha not only provides a
 basis for the study of evolution in jellyfishes through comparative
 genomics, but will also provide an important resource for studies on its
 growth and development.

title: Data from: Thermal performance curves reveal shifts in optima, limits, and breadth in early life

description: Understanding thermal performance at life stages that
 limit persistence is necessary to predict responses to climate
 change, especially for ectotherms whose fitness (survival and
 reproduction) depends on environmental temperature. Ectotherms
 often undergo stage-specific changes in size, complexity and
 duration that are predicted to modify thermal
 performance. Yet performance is mostly explored for adults, while
 performance at earlier stages that typically limit persistence
 remains poorly understood. Here, we experimentally isolate
 thermal performance curves at fertilization, embryo development
 and larval development stages in an aquatic ectotherm whose early
 planktonic stages (gametes, embryos and larvae) govern adult
 abundances and dynamics. Unlike previous studies based on
 short-term exposures, responses with unclear links to fitness or proxies
 in lieu of explicit curve descriptors (thermal optima, limits and
 breadth), we measured performance as successful completion of
 each stage after exposure throughout, and at temperatures that
 explicitly capture curve descriptors at all stages. Formal
 comparisons of descriptors using a combination of generalized
 linear mixed modelling and parametric bootstrapping reveal
 important differences among life stages. Thermal
 performance differs significantly from fertilization to embryo
 development (with thermal optimum declining by ∼2°C, thermal
 limits shifting inwards by ∼8–10°C and thermal breadth narrowing
 by ∼10°C), while performance declines independently of
 temperature thereafter. Our comparisons show that thermal
 performance at one life stage can misrepresent performance at
 others, and point to gains in complexity during embryogenesis,
 rather than subsequent gains in size or duration of exposure, as
 a key driver of thermal sensitivity in early life.

title: The U-shaped pattern of size-dependent mortality and its driving factors in a subtropical monsoon evergreen forest

description: 1. Tree mortality is an important ecological process influencing multiple
 functions of forest ecosystems. Previous studies have shown two basic
 size-mortality patterns, including a competition-driven declining and a
 disturbance-driven increasing mortality rate with tree size. Subtropical
 forests, which have a high species diversity and subject to frequent
 monsoon disturbances, are widely distributed in eastern Asia. However, the
 tree size-mortality pattern in the mature subtropical forests remains
 unclear. 2. Here we analyzed patterns of size-dependent mortality from
 tree species to forest community using a 5-year inventory data from 117
 species and 163,612 individuals in a 20-ha forest dynamic plot in a mature
 subtropical monsoon evergreen forest in eastern China. To explain the
 spatial variability in mortality patterns, two major biotic drivers
 (competition and tree size) and multiple local-scale environmental factors
 were further analyzed. 3. Our results showed that tree size was the best
 predictor of tree mortality at the scales of both species and community. A
 species-level analysis identified four size-mortality patterns that are
 shaped by species-specific attributes such as maximum size and life form.
 For 27 out of 92 species that comprised 59% of tree individuals, the
 relationship between size and mortality exhibited a U-shaped pattern of a
 first decline followed by an increase. An overall community-scale
 size-dependent mortality also showed a U-shaped pattern. 4. Tree mortality
 was also influenced by the competition and environmental conditions, but
 the relative importance varied widely across tree sizes and species. The
 competition showed significant correlations with the mortality of small
 trees, while the effect of environmental conditions on mortality was
 strongest for large trees. A principal component analysis showed that a
 combination of biotic and abiotic factors explained 42.3% of the spatial
 variation in mortality at large sizes. Synthesis. Our results reveal four
 identifiable size-dependent mortality patterns that differ across diverse
 species, jointly leading to a U-shaped mortality size pattern at the
 community level. This finding calls for the need to establish the details
 of every potential size-mortality pattern with consideration of the
 different effects of biotic and abiotic factors on tree mortality of
 specific size.

title: Advanced Cambrian hydroid fossils (Cnidaria: Hydrozoa) extend the medusozoan evolutionary history

description: Primitive cnidarians are crucial for elucidating the early evolution of
 metazoan body plans and life histories in the late Neoproterozoic and
 Palaeozoic. The highest complexity of both evolutionary aspects within
 cnidarians is found in extant hydrozoans. Many colonial hydrozoans coated
 with chitinous exoskeletons have the potential to form fossils; however,
 only a few fossils possibly representing hydroids have been reported,
 which still require scrutiny. Here, we present an exceptionally
 well-preserved hydroid found in the Upper Cambrian Fengshan Formation in
 northern China. It was originally interpreted as a problematic graptolite
 with an uncertain systematic position. Based on three characteristic
 morphological traits shared with extant hydroids (with paired hydrothecae,
 regular hydrocaulus internodes and special intrathecal origin pattern of
 hydrocladium), we propose this fossil hydroid as a new genus,
 Palaeodiphasia gen. nov., affiliated with the advanced monophyletic
 hydrozoan clade Macrocolonia typically showing loss of the medusa stage.
 More Macrocolonia fossils reviewed here indicate that this life strategy
 of medusa loss has been achieved already as early as the Middle Devonian.
 The early stratigraphical appearance of such advanced hydroid contrasts
 with previous molecular hypotheses regarding the timing of medusozoan
 evolution, and may be indicative for understanding the Ediacaran cnidarian
 radiation.

title: Visitation sequence data from: Alternative flowers affect model and mimic flower discrimination performance of bumble bees

description: Some animal-pollinated flowers produce no rewards but attract pollinators
 by imitating rewarding flowers. Termed Batesian floral mimicry, this
 phenomenon has generally been understood in terms of a common system of
 the organisms performing one of three roles as model flowers, mimic
 flowers, or signal receivers (a Batesian mimicry trinity). However,
 organisms other than those of the mimicry trinity may play important roles
 in the relationships of the trinity members.  This study examined
 the effect of alternative flowers that are dissimilar to either model or
 mimic flowers on bumble bee discrimination between model and mimic
 flowers. To this end, we observed bumble bees, Bombus ignitus (Smith),
 foraging in mixed arrays of artificial flowers mirroring either model,
 mimic, or alternative flowers.  Bumble bees’ ability to
 discriminate mimic from model flowers was impacted by the presence of
 alternative flowers; however, the effect was dependent on the similarity
 between the model and mimic flowers. This might occur because the presence
 of alternative flowers imposed an additional cognitive load on the bees’
 working memory.  Our study suggests that alternative flowers in a
 community may have beneficial effects on mimic flowers by reducing the
 discrimination performance of pollinators. A variety of environmental
 factors that impose complex sensory inputs on pollinators’ working memory
 might have contributed the maintenance of Batesian floral mimicry.

title: Row data from: Screening and response profile of Iraqi barley accessions under PEG- induced drought conditions

description: Among the abiotic stresses, drought influences plant growth and
 productivity, and plant stress responses depend on stress intensity and
 genotype. The effects of simulated drought stress on germination
 parameters were tested for tolerance and sensitivity in 59 barley
 accessions from all regions of Iraq and phenotypic, physiological and
 biochemical responses associated with drought stress were investigated.
 Stress treatments with polyethylene glycol (PEG) reduced the germination
 rate and dramatically delayed the development of the seedlings.
 Significant changes in the physiological and biochemical profiles in
 barley accessions were observed. A smaller reduction in water absorption
 of seeds was observed across all accessions, while all biochemical
 characteristics except total flavonoid content were increased with the
 increase in water deficiency in most accessions. Among the 59 barley
 accessions, ABN was the most tolerant accession, while Black-Garmiyan was
 the most drought-prone. Significant relationships were found between most
 trait pairs, with 32 significant associations under no stress, 39
 significant correlations under the 10.25% PEG treatment, and 81
 significant correlations under the 20.50% PEG treatment. According to the
 key importance analysis, seed water uptake, total phenol content, soluble
 sugar content and catalase are classified as relative significance traits
 for germination percentage, root and shoot length under stress conditions.

title: Geographic range estimates and environmental requirements for the harpy eagle derived from spatial models of current and past distribution

description: Understanding species-environment relationships is key to defining the
 spatial structure of species distributions and develop effective
 conservation plans. However, for many species this baseline information
 does not exist. With reliable presence data, spatial models that predict
 geographical ranges and identify environmental processes regulating
 distribution are a cost-effective and rapid method to achieve this. Yet
 these spatial models are lacking for many rare and threatened species,
 particularly in tropical regions. The harpy eagle (Harpia harpyja) is a
 Neotropical forest raptor of conservation concern with a continental
 distribution across lowland tropical forests in Central and South
 America.Currently the harpy eagle faces threats from habitat loss and
 persecution and is categorised as Near-Threatened by the International
 Union for the Conservation of Nature (IUCN). Within a point process
 modelling (PPM) framework, we use presence-only occurrences with climatic
 and topographical predictors to estimate current and past distributions
 and define environmental requirements using Ecological Niche Factor
 Analysis. The current PPM prediction had high calibration accuracy
 (Continuous Boyce Index = 0.838) and was robust to null expectations (pROC
 ratio = 1.407). Three predictors contributed 96 % to the PPM prediction,
 with Climatic Moisture Index the most important (72.1 %), followed by
 minimum temperature of the warmest month (15.6 %) and Terrain Roughness
 Index (8.3 %). Assessing distribution in environmental space confirmed the
 same predictors explaining distribution, along with precipitation in the
 wettest month. Our reclassified binary model estimated a current range
 size 11 % smaller than the current IUCN range polygon. Paleoclimatic
 projections combined with the current model predicted stable climatic
 refugia in the central Amazon, Guyana, eastern Colombia, and Panama. We
 propose a data-driven geographical range to complement the current IUCN
 range estimate, and that despite its continental distribution this
 tropical forest raptor is highly specialized to specific environmental
 requirements.

title: Least‐cost path analysis for urban greenways planning: a test with moths and birds across two habitats and two cities

description: 1. One of the major planning tools to respond to urban landscape
 fragmentation is the development of ecological corridors, i.e.
 interconnected networks of urban green and blue spaces. Least-cost paths
 (LCP) appear to be an easy and appropriate resistance-based modeling
 method to respond to urban planners’ needs. However, the ecological
 validation of urban corridors using LCP is rarely performed and needs to
 be generalized to different species, habitats and cities. 2. We developed
 an experimental design to test the efficiency of LCP predictions to detect
 highly connecting landscape contexts that facilitate individual movements
 compared to movements in less connecting landscape contexts. We
 deliberately assigned LCP analysis parameters based on the scientific
 literature and expert knowledge to test a method potentially easy to use
 for urban stakeholders. To extend the validation, we applied our LCP model
 to two biological taxa with different habitat requirements:
 grassland-dwelling moths and forest-dwelling passerines, and to two
 medium-sized cities. 3. We used mark-release-recapture (MRR) methods for
 moths and playback recall protocols for passerines to compare the patterns
 of individual movement between two contrasted connectivity contexts
 determined by the presence and absence of modelled LCPs. MRR protocol
 estimated movement rates between herbaceous patches and the two contrasted
 connectivity contexts. Playback recall protocol consisted in attracting
 individuals from wooded patches to the two contrasted connectivity
 contexts. A movement was considered facilitated, when displacement was
 rapidly engaged and individuals moved a long distance from their wooded
 patch. 4. Moth and passerine movement patterns differed between the two
 connectivity contexts: moth recapture rates were higher in highly
 connecting contexts than in less connecting contexts. For passerine birds,
 responses to playback recalls were faster and movement distance longer in
 highly connecting contexts. All results support the hypothesis that both
 taxa were more prone to move in corridors modeled by LCP. 5. The
 convergence of the results for different biological models and across
 cities strengthens the relevance of LCP analysis for planning urban
 greenways and provides guidelines for landscape planners in the
 development of these corridors to favor the movement and survival of
 multiple urban species.
