title: Data from: Environmental levels of neonicotinoids reduce prey consumption, mobility and emergence of the damselfly Ischnura elegans

description: Freshwaters are among the most endangered ecosystems in the world as a
 result of anthropogenic interference such as pollution. Pollution in the
 form of neonicotinoids has been intensively studied, but data thus far is
 often conflicted by contrasting responses between laboratory and field
 experiments. In addition, toxicity data are scarce and contradictory for
 insects such as Odonates (dragonflies and damselflies) and a potential
 risk to them may therefore be overlooked. We investigate the potential
 risk of neonicotinoids to Odonates by exposing nymphs of the blue‐tailed
 damselfly Ischnura elegans to environmentally relevant concentrations of
 the neonicotinoid thiacloprid. We consider I. elegans as an indicator
 species for other Odonates as it is an abundant, widespread and eurytopic
 species. We analyse the effects of thiacloprid on multiple endpoints
 (survival, consumption, growth, molting, mobility and emergence), using
 cage‐experiments as well as controlled field observations in naturally
 colonized experimental ditches. In addition, we assess sensitivity by
 either feeding the damselfly nymphs with lab‐cultured prey or by letting
 them feed freely on natural aquatic invertebrates. All sublethal endpoints
 of I. elegans are affected to some degree, and strongly depend on the food
 offered; free‐feeding nymphs are more sensitive than culture‐fed nymphs.
 Environmental relevant concentrations of thiacloprid strongly reduce the
 emergence of I. elegans and this effect is more substantial in the natural
 populations compared to the caged damselflies. This is likely explained by
 exclusion of additional biotic pressures such as predation in the caged
 experiment. Policy implications. Literature reports that one out of seven
 Odonates is threatened and 24% of the species have declining populations.
 Our observations show that current risks of neonicotinoids to Odonates are
 underestimated in laboratory experiments as the toxicity is governed by
 multiple biotic factors such as food quantity/quality and predation. Given
 the widespread abundance of blue‐tailed damselfly Ischnura elegans, the
 observed sensitivity to neonicotinoids and current population trends of
 this species, these results indicate neonicotinoids play a central role in
 the Odonate decline in general.

title: Data from: Urbanisation-driven homogenisation is more pronounced and happens at wider spatial scales in nocturnal and mobile flying insects

description: Aim We test whether urbanisation drives biotic homogenisation. We
 hypothesise that declines in abundance and species diversity of aerial
 insects are exacerbated by the urbanisation-driven loss of species with
 low habitat generalism, mobility and warm-adaptedness. We predict this
 homogenisation to be more pronounced for nocturnal taxa, and at wider
 scales for mobile taxa. Location Belgium Time period Summers 2014-2015
 Major taxa studied Lepidoptera Methods We compare communities along
 urbanisation gradients using a shared, replicated and nested sampling
 design, in which butterflies were counted within 81 grassland and
 macro-moths light-trapped in 12 woodland sites. We quantify taxonomic and
 functional community composition, the latter via community-weighted means
 and variation of species-specific traits related to specialisation,
 mobility and thermophily. Using linear regression models, variables are
 analysed in relation to site-specific urbanisation values quantified at
 seven scales (50-3200 m radii). At best-fitting scales, we test for
 taxonomic homogenisation. Results With increasing urbanisation, abundance,
 species richness and Shannon diversity severely declined, with butterfly
 and macro-moth declines due to local- versus landscape-scale urbanisation
 (200 vs. 800-3200 m radii, respectively). While taxonomic homogenisation
 was absent for butterflies, urban macro-moth communities displayed higher
 nestedness than non-urban communities. Overall, communities showed mean
 shifts towards generalist, mobile and thermophilous species, displaying
 trait convergence too. These functional trait models consistently fit best
 with urbanisation quantified at local scales (100-200 m radii) for
 butterfly communities, and at local to wider landscape scales (200-800 m
 radii) for macro-moth communities. Main conclusions Urban communities
 display functional homogenisation which follows urbanisation at scales
 linked to taxon-specific mobility. Light pollution may explain why
 homogenisation was more pronounced for the nocturnal taxon. We discuss
 that urbanisation is likely to impact flying insect communities across the
 globe, but also that impacts on their ecosystem functions and services
 could be mitigated via multi-scale implementation of urban green
 infrastructure.

title: Data from: Local and regional drivers of taxonomic homogenization in stream communities along a land use gradient

description: Aim: The interaction of land use with local vs. regional processes driving
 biological homogenization (β-diversity loss) is poorly understood. We
 explored: i) stream β-diversity responses to land cover (forest vs.
 agriculture) in terms of physicochemistry and physicochemical
 heterogeneity, ii) whether these responses were constrained by the
 regional species pool, i.e. γ-diversity, or local assembly processes
 through local (α) diversity, iii) if local assembly operated through the
 regional species abundance distribution (SAD) or intraspecific spatial
 aggregation, and iv) the dependency on body size, dispersal capacity, and
 trophic level (producer vs. consumer). Location: United States of America,
 Canada, and France Time Period: 1993-2012 Major Taxa Studied: Stream
 diatoms, insects, and fish Methods: We analyzed six datasets totaling
 1,225 stream samples. We compared diversity responses to eutrophication
 and physicochemical heterogeneity in forested vs. agricultural streams
 with regression methods. Null models quantified contribution of local
 assembly to β-diversity (β-deviance, βDEV) for both land covers and
 partitioned it into fractions explained by the regional SAD (βSAD) vs.
 aggregation (βAGG). Results: Eutrophication explained homogenization and
 more uneven regional SADs across groups, but local and regional
 biodiversity responses differed across taxa. βDEV was insensitive to land
 use. βSAD largely exceeded βAGG and was higher in agriculture. Main
 Conclusion: Eutrophication but not physicochemical heterogeneity of
 agricultural streams underlay β-diversity loss in diatoms, insects and
 fish. Agriculture did not constrain the magnitude of local vs. regional
 effects on β-diversity, but controlled the local assembly mechanisms.
 While the SAD fraction dominated in both land covers, it further increased
 in agriculture at the expense of aggregation. Notably, the regional SADs
 were more uneven in agriculture, exhibiting excess common species or
 stronger dominance. Diatoms and insects diverged from fish in terms of
 biodiversity, SAD shape, and βDEV patterns, suggesting an overriding role
 of body size and/or dispersal capacity compared to trophic position.

title: Data from: Do traits and phylogeny support congruent community diversity patterns and assembly inferences?

description: 1. It is now commonplace in community ecology to assess patterns of
 phylogenetic or functional diversity in order to inform our understanding
 of the assembly mechanisms that structure communities. While both
 phylogenetic and functional approaches have been used in conceptually
 similar ways, it is not clear if they both in fact reveal similar
 community diversity patterns or support similar inferences. We review
 studies that use both measures to determine the degree to which they
 support congruent patterns and inferences about communities. 2. We
 performed a literature review with 188 analyses from 79 published papers
 that compared some facet of phylogenetic (PD) and functional diversity
 (FD) in community ecology. These studies generally report four main cases
 in which phylogenetic and functional information are used together in
 community analyses, to determine if: 1) there were phylogenetic signals in
 the measured traits; 2) PD and FD were correlated with one another; 3)
 standardized PD and FD measures similarly revealed patterns of community
 over- or under-dispersion; and 4) PD and FD were both related to other
 explanatory variables (e.g., elevation) similarly. 3. We found that the
 vast majority of studies found both strong phylogenetic signals in their
 traits and positive correlations of PD and FD measures across sites.
 However, and surprisingly, we found substantial incongruencies for the
 other tests. Phylogenetic and functional dispersion patterns were
 congruent only about half the time. Specifically, when communities were
 phylogenetically over-dispersed, these same communities were more likely
 to be functionally under-dispersed. Similarly, we found that phylogenetic
 and functional relationships with independent predictors were incongruent
 in about half of the analyses. 4. Synthesis. Phylogenetic signal tests and
 PD-FD correlations appear to strongly support the congruence between
 traits and phylogeny. It is surprising that strong phylogenetic signals
 appeared so ubiquitous given that ecological studies often analyze
 phylogenetically incomplete sets of species that have undergone ecological
 sorting. Despite the largely congruent findings based on phylogenetic
 signal tests and PD-FD correlations, we found substantial incongruencies
 when researchers assessed either dispersion patterns or relationships with
 independent predictors. We discuss a number of potential ecological,
 evolutionary and methodological reasons for these incongruencies.
 Phylogenetic and functional information might reflect species ecological
 differences unequally with phylogenies better reflecting multivariate
 conserved elements of ecological similarity, and single traits better able
 to capture recent divergence.

title: Data from: Individual niche trajectories drive fitness variation

description: 1. Variation in fitness across individuals is central to population
 growth, species coexistence, and evolution by natural selection. Fitness
 variation associated with resource use is hugely consequential, but how
 this variation is generated and maintained within natural populations
 remains unclear. In particular, individual fitness may depend on many
 cumulative foraging decisions over time, but this hypothesis remains
 untested. 2. We used multi-tissue stable isotope analysis to determine
 isotopic niche trajectories within species, populations and sexes of
 thin-toed frogs, and explored how this temporal dimension of diet affects
 individual reproductive investment, body condition, and parasite load. 3.
 We found that individual frogs shifted their diets less than expected
 under a null model, likely due to functional tradeoffs that limit the
 incorporation of new prey types over time. However, within the observed
 range of diet shifts, individuals that modified their diet to a greater
 degree exhibited higher fitness, although this effect was sex-dependent.
 4. We suggest that these different relationships between isotopic niche
 trajectory length and fitness within thin-toed frogs are driven by
 variability in the resource environment, negative density-dependence and
 allometric constraints. These strong fitness effects suggest that the
 temporal dimension of diet change is a potential target of natural
 selection and, therefore, could drive correlated evolution in phenotypic
 traits underlying diet flexibility. Our findings add a new level of
 complexity to the understanding of ecological and evolutionary
 consequences of niche variation by demonstrating that temporal variation
 in foraging consistency within populations leads to different fitness
 payoffs.

title: Data from: Leaf litter traits predominantly control litter decomposition in streams worldwide

description: Aim Leaf litter decomposition in freshwater ecosystems is a vital process
 linking ecosystem nutrient cycling, energy transfer, and trophic
 interactions. In comparison to terrestrial ecosystems, in which
 researchers find that litter traits predominantly regulate its
 decomposition worldwide, the dominant factors controlling litter
 decomposition in aquatic ecosystems are still debated with global patterns
 not well documented. Here, we aimed to explore general patterns and key
 drivers (e.g. litter traits, climate, and water characteristics) of leaf
 litter decomposition in streams worldwide. Location Global Time period
 1977-2018 Leaf litter Methods We synthesized 1707 records of litter
 decomposition in streams from 275 studies. We explored variations in
 decomposition rates among climate zones, tree functional types, and
 between mesh size groups. Regressions were performed to identify the
 factors that play dominant roles in litter decomposition globally. Results
 Litter decomposition rates did not differ among tropical, temperate, and
 cold climate zones. Decomposition rates of litter from evergreen conifer
 trees (EC) were much lower than those of deciduous and evergreen
 broad-leaf trees (DB and EB), attributed to the low quality of litter from
 EC. No significant differences were found between decomposition rates of
 DB and EB. Additionally, litter decomposition rates were much higher in
 coarse- than in fine-mesh bags, which control the entrance of decomposers
 of different body sizes. Multiple regressions showed that litter traits
 (including lignin, C:N ratio) and altitude were the most important factors
 in regulating leaf litter decomposition. Main conclusions Litter traits
 predominantly control leaf litter decomposition in streams worldwide.
 While further analyses are necessary to explore whether commonalities of
 litter traits’ predominant role in decomposition exist in both aquatic and
 terrestrial ecosystems, our findings could contribute to using trait-based
 approaches in modeling the decomposition of litter in streams globally and
 exploring mechanisms of land-water-atmosphere carbon fluxes.

title: Data from: Depth and vertical hydrodynamics constrain the size–structure of a lowland streambed community

description: Abundance-body mass (N–M) relationships are prominent macroecological
 patterns and provide an integrated measurement of the structure and energy
 flow through natural communities. However, little is known about how N-M
 relationships are constrained by local environmental conditions. Here we
 quantify how sediment depth and direction of surface–groundwater exchange
 (vertical hydrodynamics), two major drivers of the streambed ecology,
 determine N-M scaling in a sandy lowland, European stream. Streambed
 assemblages included flagellates, ciliates, meiofauna and
 macroinvertebrates, and spanned five orders of magnitude in body mass. We
 detected a significant interaction of body mass with depth and vertical
 hydrodynamics with a sharp reduction in N–M slopes in the hyporheic zone
 and under upwelling conditions. These results revealed that streambed
 assemblages become more size–structured as environmental constraints
 increase with direct implications for the metabolic capacity and
 functioning of the system.

title: Data from: A simple method to estimate the probable distribution of species

description: Species distribution models (SDMs) are broadly used to predict species
 distributions from available presence data. However, SDMs results have
 been criticized for several reasons mainly related to two basic
 characteristics of most SDMs: 1) general lack of reliable species absence
 information, 2) the frequent use of an arbitrary geographical extent (GE)
 or accessible area of the species. These impediments have motivated us to
 generate a procedure called Niche of Occurrence (NOO). NOO provides the
 probable distribution of species (realized niche) relying solely on
 partial information about presence of species. It operates within a
 natural geographical extent delimited by available observations and avoids
 using misleading thresholds to obtain binary presence‐absence estimations
 when the species prevalence is unknown. In this study the main
 characteristics of NOO are presented, comparing its performance with other
 recognized and more complex SDMs by using virtual species to avoid the
 omnipresent error sources of real data sets.

title: Data from: The dynamics of men's cooperation and social status in a small-scale society

description: We propose that networks of cooperation and allocation of social status
 co-emerge in human groups. We substantiate this hypothesis with one of the
 first longitudinal studies of cooperation in a preindustrial society,
 spanning eight years. Using longitudinal social network analysis of
 cooperation among men, we find large effects of kinship, reciprocity, and
 transitivity in nomination of cooperation partners over time. Independent
 of these effects, we show that (i) higher status individuals gain more
 cooperation partners, and (ii) individuals gain status by cooperating with
 individuals of higher status than themselves. We posit that human
 hierarchies are more egalitarian relative to other primates species, due
 in part to greater interdependence between cooperation and status
 hierarchy.

title: SPIKEPIPE: A metagenomic pipeline for the accurate quantification of eukaryotic species occurrences and intraspecific abundance change using DNA barcodes or mitogenomes

description: The accurate quantification of eukaryotic species abundances from bulk
 samples remains a key challenge for community ecology and environmental
 biomonitoring. We resolve this challenge by combining shotgun sequencing,
 mapping to reference DNA barcodes or to mitogenomes, and three correction
 factors: (a) a percent‐coverage threshold to filter out false positives,
 (b) an internal‐standard DNA spike‐in to correct for stochasticity during
 sequencing, and (c) technical replicates to correct for stochasticity
 across sequencing runs. The SPIKEPIPE pipeline achieves a strikingly high
 accuracy of intraspecific abundance estimates (in terms of DNA mass) from
 samples of known composition (mapping to barcodes R2 = .93, mitogenomes R2
 = .95) and a high repeatability across environmental‐sample replicates
 (barcodes R2 = .94, mitogenomes R2 = .93). As proof of concept, we
 sequence arthropod samples from the High Arctic, systematically collected
 over 17 years, detecting changes in species richness, species‐specific
 abundances, and phenology. SPIKEPIPE provides cost‐efficient and reliable
 quantification of eukaryotic communities.

title: Data from: Is there coordination of leaf and fine root traits at local scales? a test in temperate forest swamps

description: Examining the coordination of leaf and fine root traits not only aids a
 better understanding of plant ecological strategies from a whole-plant
 perspective, but also helps improve the prediction of belowground
 properties from aboveground traits. The relationships between leaf and
 fine root traits have been extensively explored at global and regional
 scales, but remain unclear at local scales. Here, we measured six pairs of
 analogous leaf and fine root traits related to resource economy and organ
 size for coexisting dominant and subordinate vascular plants at three
 successional stages of temperate forest swamps in Lingfeng National Nature
 Reserve in the Greater Hinggan Mountains, NE China. Leaf and fine root
 traits related with resource acquisition (e.g. specific leaf area [SLA],
 leaf N, leaf P, root water content and root P) decreased with succession.
 Overall, we found strong linear relationships between leaf dry matter
 content (LDMC) and root water content, and between leaf and root C, N and
 P concentrations, but only weak correlations were observed between leaf
 area and root diameter, and between SLA and specific root length (SRL).
 The strong relationships between LDMC and root water content and between
 leaf and root C, N and P held at the early and late stages, but
 disappeared at the middle stage. Besides, C and P of leaves were
 significantly correlated with those of roots for woody plants, while
 strong linkages existed between LDMC and root water content and between
 leaf N and root N for herbaceous species. These results provided evidence
 for the existence of strong coordination between leaf and root traits at
 the local scale. Meanwhile, the leaf-root trait relationships could be
 modulated by successional stage and growth form, indicating the complexity
 of coordination of aboveground and belowground traits at the local scale.
