title: Data from: Understanding human queuing behaviour at exits: an empirical study

description: The choice of the exit to egress from a facility plays a fundamental role
 in pedestrian modelling and simulation. Yet, empirical evidence for
 backing up simulation is scarce. In this contribution, we present three
 new groups of experiments that we conducted in different geometries. We
 varied parameters such as the width of the doors, the initial location and
 number of pedestrians which in turn affected their perception of the
 environment. We extracted and analysed relevant indicators such as
 distance to the exits and density levels. The results put in evidence the
 fact that pedestrians use time-dependent information to optimize their
 exit choice, and that, in congested states, a load balancing over the
 exits occurs. We propose a minimal modelling approach that covers those
 situations, especially the cases where the geometry does not show a
 symmetrical configuration. Most of the models try to achieve the load
 balancing by simulating the system and solving optimization problems. We
 show statistically and by simulation that a linear model based on the
 distance to the exits and the density levels around the exit can be an
 efficient dynamical alternative.

title: Data from: Species interactions increase the temporal stability of community productivity in Pinus sylvestris-Fagus sylvatica mixtures across Europe

description: 1.There is increasing evidence that species diversity enhances the
 temporal stability of community productivity in different ecosystems,
 although its effect at population and tree levels seems to be negative or
 neutral. Asynchrony in species responses to environmental conditions was
 found to be one of the main drivers of this stabilizing process. However,
 the effect of species mixing on the stability of productivity, and the
 relative importance of the associated mechanisms, remain poorly understood
 in forest communities. 2.We investigated the way mixing species influenced
 the temporal stability of productivity in Pinus sylvestris L. and Fagus
 sylvatica L. forests, and attempted to determine the main drivers among
 overyielding, asynchrony between species annual growth responses to
 environmental conditions, and temporal shifts in species interactions. We
 used a network of 93 experimental plots distributed across Europe to
 compare the temporal stability of basal area growth over a 15-year period
 (1999-2013) in mixed and monospecific forest stands at different
 organizational levels, namely community, population and individual tree
 levels. 3.Mixed stands showed a higher temporal stability of basal area
 growth than monospecific stands at the community level, but not at the
 population or individual tree levels. Temporal stability at the community
 level was related to asynchrony between species growth in mixtures, but
 not to overyielding nor to asynchrony between species growth in
 monospecific stands. Temporal shifts in species interactions were also
 related to asynchrony and to the mixing effect on temporal stability.
 4.Synthesis. Our findings confirm that species mixing can stabilize
 productivity at the community level whereas there is a neutral or negative
 effect on stability at the population and individual tree levels. The
 contrasting findings regarding the relationships between temporal
 stability and asynchrony in species growth in mixed and monospecific
 stands suggest that the main driver in the stabilizing process may be the
 temporal niche complementarity between species rather than differences in
 species’ intrinsic responses to environmental conditions.

title: Data from: Comparative leaf anatomy of wild Manihot Mill. species (Euphorbiaceae) from Chapada Diamantina, Bahia, Brazil

description: The leaf anatomy of nine species of Manihot Mill. were studied with the
 objective of finding anatomical features that contribute to understanding
 the taxonomy of the genus. Leaf samples were collected in the field and
 from herbarium specimens, and standardized methods were used for both
 light and scanning electron microscopy. The following species were
 studied: M. bellidifolia P. Carvalho & M. Martins, M. brachyandra
 Pax & K. Hoffm., M. caerulescens Pohl, M. diamantinensis Allem, M.
 elongata sp. nov. ined., M. jacobinensis Müll. Arg. (I), M. jacobinensis
 Müll. Arg. (II), M. longiracemosa P. Carvalho & M. Martins, M.
 maracasensis Ule, M. reniformis Pohl, M. tripartita (Spreng) Müll. Arg.
 and Manihot sp. Anatomically, the analysis revealed differences that
 indicate the importance of leaf anatomy in the taxonomy of the species.
 Presence of fibers in the bundle sheath, presence or absence of papillae
 and fibers in the midrib are diagnostic characters. Although these
 characteristics were not enough to separate all of the species, or to
 group them into a section, they did show some taxonomic importance at the
 species level. In addition, morphoanatomical differences and geographical
 distribution support Manihot sp. as a distinct species.

title: Data from: Evolutionary potential of morphological traits across different life-history stages

description: Despite accumulating examples of selection acting on heritable traits in
 the wild, predicted evolutionary responses are often different from
 observed phenotypic trends. Various explanations have been suggested for
 these mismatches. These include within-individual changes across lifespan
 that can create important variation in genetic architecture of traits and
 selection acting on them, but also potential problems with the
 methodological approach used to predict evolutionary responses of traits.
 Here, we used an 8-year data set on tree swallow (Tachycineta bicolor) to
 first assess the effects of differences among three nestling life-history
 stages on the genetic (co)variances of two morphological traits (body mass
 and primary feather length) and the selection acting on them over three
 generations. We then estimated the evolutionary potential of these traits
 by predicting their evolutionary responses using the breeder's
 equation and the secondary theorem of selection approaches. Our results
 showed variation in strength and direction of selection and slight changes
 in trait variance across ages. Predicted evolutionary responses differed
 importantly between both approaches for half of the trait–age combinations
 we studied, suggesting the presence of environmentally induced
 correlations between focal traits and fitness possibly biasing
 breeder's equation predictions. Our results emphasize that
 predictions of evolutionary potential for morphological traits are likely
 to be highly variable, both in strength and direction, depending on the
 life stage and method used, thus mitigating our capacity to predict
 adaptation and persistence of wild populations.

title: Data from: Archaea and bacteria mediate the effects of native species root loss on fungi during plant invasion

description: Although invasive plants can drive ecosystem change, little is known about
 the directional nature of belowground interactions between invasive
 plants, native roots, bacteria, archaea and fungi. We used detailed
 bioinformatics and a recently developed root assay on soils collected in
 fescue grassland along a gradient of smooth brome (Bromus inermis Leyss)
 invasion to examine the links between smooth brome shoot litter and root,
 archaea, bacteria and fungal communities. We examined (1) aboveground
 versus belowground influences of smooth brome on soil microbial
 communities, (2) the importance of direct versus microbe-mediated impacts
 of plants on soil fungal communities, and (3) the web of roots, shoots,
 archaea, bacteria and fungi interactions across the A and B soil horizons
 in invaded and non-invaded sites. Archaea and bacteria influenced fungal
 composition, but not vice versa, as indicated by redundancy analyses.
 Co-inertia analyses suggested that bacterial–fungal variance was driven
 primarily by 12 bacterial operational taxonomic units (OTUs). Brome
 increased bacterial diversity via smooth brome litter in the A horizon and
 roots in the B horizon, which then reduced fungal diversity. Archaea
 increased abundance of several bacterial OTUs, and the key bacterial OTUs
 mediated changes in the fungi’s response to invasion. Overall, native root
 diversity loss and bacterial mediation were more important drivers of
 fungal composition than were the direct effects of increases in smooth
 brome. Critically, native plant species displacement and root loss
 appeared to be the most important driver of fungal composition during
 invasion. This causal web likely gives rise to the plant–fungi feedbacks,
 which are an essential factor determining plant diversity in invaded
 grassland ecosystems.

title: Data from: Entangled fates of holobiont genomes during invasion: nested bacterial and host diversities in Caulerpa taxifolia

description: Successful prevention and mitigation of biological invasions requires
 retracing the initial steps of introduction, as well as understanding key
 elements enhancing the adaptability of invasive species. We studied the
 genetic diversity of the green alga Caulerpa taxifolia and its associated
 bacterial communities in several areas around the world. The striking
 congruence of α and ß diversity of the algal genome and endophytic
 communities reveals a tight association, supporting the holobiont concept
 as best describing the unit of spreading and invasion. Both genomic
 compartments support the hypotheses of a unique accidental introduction in
 the Mediterranean and of multiple invasion events in Southern Australia.
 In addition to helping with tracing the origin of invasion, bacterial
 communities exhibit metabolic functions that can potentially enhance
 adaptability and competitiveness of the consortium they form with their
 host. We thus hypothesize that low genetic diversities of both host and
 symbiont communities may contribute to the recent regression in the
 Mediterranean, in contrast with the persistence of highly diverse
 assemblages in southern Australia. This study supports the importance of
 scaling up from the host to the holobiont for a comprehensive
 understanding of invasions.

title: Data from: Selection on parental performance opposes selection for larger body mass in a wild population of blue tits

description: There is abundant evidence in many taxa for positive directional selection
 on body size, and yet little evidence for microevolutionary change. In
 many species, variation in body size is partly determined by the actions
 of parents, so a proposed explanation for stasis is the presence of a
 negative genetic correlation between direct and parental effects.
 Consequently, selecting genes for increased body size would result in a
 correlated decline in parental effects, reducing body size in the
 following generation. We show that these arguments implicitly assume that
 parental care is cost free, and that including a cost alters the predicted
 genetic architectures needed to explain stasis. Using a large
 cross-fostered population of blue tits, we estimate direct selection on
 parental effects for body mass, and show it is negative. Negative
 selection is consistent with a cost to parental care, mainly acting
 through a reduction in current fecundity rather than survival. Under these
 conditions, evolutionary stasis is possible for moderately negative
 genetic correlations between direct and parental effects. This is in
 contrast to the implausibly extreme correlations needed when care is
 assumed to be cost free. Thus, we highlight the importance of accounting
 correctly for complete selection acting on traits across generations.

title: Data from: Interpreting and predicting the spread of invasive wild pigs

description: The eruption of invasive wild pigs (IWPs) Sus scrofa throughout the world
 exemplifies the need to understand the influences of exotic and non-native
 species expansions. In particular, the continental USA is precariously
 threatened by a rapid expansion of IWPs, and a better understanding of the
 rate and process of spread can inform strategies that will limit the
 expansion. We developed a spatially and temporally dynamic model to
 examine three decades (1982–2012) of IWP expansion, and predict the spread
 of IWPs throughout the continental USA, relative to where IWPs previously
 inhabited. We used the model to predict where IWPs are likely to invade
 next. The average rate of northward expansion increased from 6.5 to 12.6
 km per year, suggesting most counties in the continental USA could be
 inhabited within the next 3–5 decades. The spread of IWPs was primarily
 associated with expansion into areas with similar environmental
 characteristics as their previous range, with the exception of spreading
 into colder regions. We identified that climate change may assist spread
 into northern regions by generating milder winters with less snow.
 Otherwise, the spread of IWPs was not dependent on agriculture,
 precipitation, or biodiversity at the county level. The model correctly
 predicted 86% of counties that were invaded during 2012, and those
 predictions indicate that large portions of the USA are in immediate
 danger of invasion. Synthesis and applications. Anti-invasion efforts
 should focus along the boundaries of current occupied range to stop
 natural expansion, and anti-invasion policies should focus on stopping
 anthropogenic transport and release of invasive wild pigs (IWPs). Our
 results demonstrate the utility of a spatio-temporal examination to inform
 strategies for limiting the spread of IWPs.

title: Data from: Life cycle size dynamics in Didymosphenia geminata (Bacillariophytceae)

description: Didymosphenia geminata has received a great deal of attention in the last
 25 years, and considerable effort has gone into determining the origin,
 ecological impact, and economic consequences of its invasive behavior.
 While environmental conditions are a controlling influence in
 distribution, the extreme success of the species may be tied to its basic
 biology and life history. Little is known, however, about population
 dynamics, size restoration and reproduction of D. geminata. The objective
 of this study was to determine the temporal patterns in cell size
 frequency, size restoration strategy, and synchronization of life cycles
 between populations in close proximity. We implemented FlowCam technology
 to measure the length of more than 100,000 D. geminata cells from two
 sites in South Boulder Creek, Colorado over 1 year. We applied finite
 mixture modeling to uncover temporal patterns in size distribution. Our
 results show that collections of D. geminata exhibited a complex,
 multimodal size distribution, almost always containing four overlapping
 age cohorts. We failed to observe direct visual evidence of the sexual
 phase. Multiple abrupt and directional shifts in size distribution,
 however, were documented providing conclusive evidence of cell size
 restoration. Lastly, nodules in close proximity were asynchronous with
 respect to size frequency profiles and size diminution, highlighting the
 relevance of spatial heterogeneity in in situ diatom size dynamics. This
 study is the first to document the complexity of diatom cell size
 distribution in a lotic system, size restoration in D. geminata, and the
 variability in rates of size reduction at microhabitat spatial scales.

title: Data from: Increasing cognitive load attenuates right arm swing in healthy human walking

description: Human arm swing looks and feels highly automated, yet it is increasingly
 apparent that higher centres, including the cortex, are involved in many
 aspects of locomotor control. The addition of a cognitive task increases
 arm swing asymmetry during walking, but the characteristics and mechanism
 of this asymmetry are unclear. We hypothesized that this effect is
 lateralized and a Stroop word-colour naming task—primarily involving left
 hemisphere structures—would reduce right arm swing only. We recorded gait
 in 83 healthy subjects aged 18–80 walking normally on a treadmill and
 while performing a congruent and incongruent Stroop task. The primary
 measure of arm swing asymmetry—an index based on both three-dimensional
 wrist trajectories in which positive values indicate proportionally
 smaller movements on the right—increased significantly under dual-task
 conditions in those aged 40–59 and further still in the over-60s, driven
 by reduced right arm flexion. Right arm swing attenuation appears to be
 the norm in humans performing a locomotor-cognitive dual-task, confirming
 a prominent role of the brain in locomotor behaviour. Women under 60 are
 surprisingly resistant to this effect, revealing unexpected gender
 differences atop the hierarchical chain of locomotor control.

title: Data from: Conspicuousness, color resemblance, and toxicity in geographically diverging mimicry: the pan-Amazonian frog Allobates femoralis

description: Predation risk is allegedly reduced in Batesian and Müllerian mimics,
 because their coloration resembles the conspicuous coloration of
 unpalatable prey. The efficacy of mimicry is thought to be affected by
 variation in the unpalatability of prey, the conspicuousness of the
 signals, and the visual system of predators that see them. Many frog
 species exhibit small colorful patches contrasting against an otherwise
 dark body. By measuring toxicity and color reflectance in a geographically
 variable frog species and the syntopic toxic species, we tested whether
 unpalatability was correlated with between-species color resemblance and
 whether resemblance was highest for the most conspicuous components of
 coloration pattern. Heterospecific resemblance in colorful patches was
 highest between species at the same locality but unrelated to concomitant
 variation in toxicity. Surprisingly, resemblance was lower for the
 conspicuous femoral patches compared to the inconspicuous dorsum. By
 building visual models, we further tested whether resemblance was affected
 by the visual system of model predators. As predicted, mimic-model
 resemblance was higher under the visual system of simulated predators
 compared to no visual system at all. Our results indicate that femoral
 patches are aposematic signals and support a role of mimicry in driving
 phenotypic divergence or mimetic radiation between localities.
