title: Biomass allocation and productivity–richness relationship across four grassland types at the Qinghai Plateau

description: Aboveground biomass (AGB) and belowground biomass (BGB) allocation and
 productivity–richness relationship are controversial. Here, we assessed
 AGB and BGB allocation and the productivity–richness relationship at
 community level across four grassland types based on the biomass data
 collected from 80 sites across the Qinghai Plateau during 2011–2012. The
 reduced major axis regression and general linear models were used and
 showed that (1) the median values of AGB were significantly higher in
 alpine meadow than in other three grassland types; the ratio of root to
 shoot (R/S) was significantly higher in desert grassland (36.06) than
 intemperate grassland (16.60), alpine meadow (13.35) and meadow steppe
 (19.46). The temperate grassland had deeper root distribution than the
 other three grasslands, with about 91.45% roots distributed in the top 30
 cm soil layer. (2) The slopes between log AGB and log BGB in the temperate
 grassland and meadow steppe were 1.09 and 1, respectively, whereas that in
 the desert grassland was 1.12, which was significantly different from the
 isometric allocation relationship. A competitive relationship between AGB
 and BGB was observed in the alpine meadow with a slope of −1.83,
 indicating a trade-off between AGB and BGB in the alpine meadow. (3) A
 positive productivity–richness relationship existed across the four
 grassland types, suggesting that the positive productivity–richness
 relationship might not be affected by the environmental factors at the
 plant location. Our results provide a new insight for biomass allocation
 and biodiversity–ecosystem functioning research.
description: We harvested the AGB and BGB across 80 sites on the
 Qinghai–Tibetan Plateau once during summer (July to September) in 2011 and
 2012. Five quadrats of 0.25 m<sup>2</sup> (0.5 × 0.5 m) were
 sampled in the alpine meadow at each site (100 × 10 m) due to the abundant
 AGB in alpine meadow, and five quadrats of 1 m<sup>2</sup> (1
 ×1m) were sampled in the temperate grassland, desert grassland, and meadow
 steppe at each site.

title: Great smoky mountain ant community composition

description: Disentangling the drivers of diversity gradients can be challenging. The
 Measurement of Biodiversity (MoB) framework decomposes scale-dependent
 changes in species diversity into three components of community structure:
 the species abundance distribution (SAD), the total community abundance,
 and the within-species spatial aggregation. Here we extend MoB from
 categorical treatment comparisons to quantify variation along continuous
 geographic or environmental gradients. Our approach requires sites along a
 gradient, each consisting of georeferenced plots of abundance-based
 species composition data. We demonstrate our method using a case study of
 ants sampled along an elevational gradient of 28 sites in a mixed
 deciduous forest of the Great Smoky Mountains National Park, USA. MoB
 analysis revealed that decreases in ant species richness along the
 elevational gradient were associated with decreasing evenness and total
 number of species which counteracted the modest increase in richness
 associated with decreasing spatial aggregation along the gradient. Total
 community abundance had a negligible effect on richness at all but the
 finest spatial grains, SAD effects increased in importance with sampling
 effort, while the aggregation effect had the strongest effect at coarser
 spatial grains. These results do not support the more-individuals
 hypothesis, but they are consistent with a hypothesis of stronger
 environmental filtering at coarser spatial grains. Our extension of MoB
 has the potential to elucidate how components of community structure
 contribute to changes in diversity along environmental gradients and
 should be useful for a variety of assemblage-level data collected along
 gradients.
description: Sites ranged in elevation from 379-1828 m and were in relatively
 undisturbed deciduous forest sites, away from trails. At each site, we
 randomly placed a 50 × 50 m plot, from which 16
 1-m<sup>2</sup> quadrats were arranged in a nested design: 10
 x 10 m subplots were placed in the corners of each 50 x 50 m plot, and
 1-m<sup>2</sup> quadrats were placed in the corners of each 10
 x 10 m subplot, for a total of 16 1-m<sup>2</sup> quadrats per
 site. Ants were sampled by collecting all of the leaflitter within each
 quadrat and sifting through it with a coarse mesh screen (1-cm grid) to
 remove the largest fragments and concentrate the fine litter. Concentrated
 litter from each quadrat was then put in its own mini-Winkler sacks for 2
 days in the lab. After 2 days, all worker ants were extracted and
 enumerated.

title: No evidence for an adaptive role of early molt into breeding plumage in a female fairy-wren

description: The evolution of ornaments as sexually selected signals is well understood
 in males, but female ornamentation remains understudied. Fairy-wrens offer
 an excellent model system, given their complex social structure and mating
 systems, and the diversity of female ornamentation. We investigated
 whether early molt into ornamental breeding plumage plays an adaptive role
 in females of the monogamous purple-crowned fairy-wren Malurus coronatus,
 the only fairy-wren known to have female seasonal plumage. Using six years
 of monitoring, we found that timing of female molt was similar to males,
 but there was no evidence for assortative mating. Like males (previous
 study), older and dominant individuals acquired their breeding plumage
 earlier; however, in contrast to males, early molt did not seem to be
 costly since unfavourable environmental conditions or previous
 reproductive effort did not delay molt. Early female molt was not
 associated with any indicator of reproductive quality nor did it attract
 additional offspring care by their partners. We also found no association
 between early molt and the likelihood of acquiring a dominant (breeding)
 position, or with the presence or proximity to same-sex rivals. Our study
 results, that are similar to previous findings in conspecific males,
 suggests that directional selection for early molt might be relaxed in
 this species, in contrast to other genetically polygamous fairy-wrens in
 which early molt predicts extra-pair mating success in males. However, the
 finding that molt timing is status-dependent raises the possibility that
 other attributes of the ornament may fulfil an adaptive function in
 females.

title: Do selfing species have greater niche breadth? Support from ecological niche modeling

description: We explore the relationship between plant mating system (selfing or
 outcrossing) and niche breadth to gain new insights into processes that
 drive species distributions. Using a comparative approach with highly
 selfing versus highly outcrossing sister species, we test the extent to
 which: (1) species pairs have evolved significant niche divergence and
 less niche overlap, (2) selfers have wider niche breadths than outcrossers
 or vice versa, and (3) niches of selfers and outcrossers are defined by
 significant differences in environmental variables. We applied predictive
 ecological niche modeling approaches to estimate and contrast niche
 divergence, overlap and breadth, and to identify key environmental
 variables associated with each species’ niche for seven sister species
 with divergent mating systems. Data from 4862 geo-referenced herbarium
 occurrence records were compiled for 14 species in Collinsia and Tonella
 (Plantaginaceae) and 19 environmental variables associated with each
 record. We found sister species display significant niche divergence,
 though not as a function of divergence time, and overall, selfers have
 significantly wider niche breadths compared to their outcrossing sisters.
 Our results suggest that a selfing mating system likely contributes to the
 greater capacity to reach, reproduce, establish, and adapt to new
 habitats, which increases niche breadth of selfers.

title: Data from: Visual system development of the spotted unicornfish, Naso brevirostris (Acanthuridae)

description: Ontogenetic changes of the visual system are often correlated to shifts in
 habitat and feeding behaviour of animals. Coral reef fishes begin their
 lives in the pelagic zone and then migrate to the reef. This habitat
 transition frequently involves a change in diet and light environment as
 well as major morphological modifications. The spotted unicornfish, Naso
 brevirostris, is known to shift diet from zooplankton to algae and back to
 mainly zooplankton when transitioning from larval to juvenile and then to
 adult stages. Concurrently, N. brevirostris also moves from an open
 pelagic to a coral-associated habitat before migrating up in the water
 column when reaching adulthood. Using retinal mapping techniques, we
 discovered that the distribution and density of ganglion and photoreceptor
 cells in N. brevirostris mostly changes during the transition from the
 larval to the juvenile stage, with only minor modifications thereafter.
 Similarly, visual gene (opsin) expression based on RNA sequencing,
 although qualitatively similar between stages (all fishes mainly expressed
 the same three cone opsins; SWS2B, RH2B, RH2A), also showed the biggest
 quantitative difference when transitioning from larvae to juveniles. The
 juvenile stage in particular seems mismatched with its reef-associated
 ecology, which may be due to this stage only lasting a fraction of the
 lifespan of these fishes. Hence, the visual ontogeny found in N.
 brevirostris is very different from the progressive changes found in other
 reef fishes calling for a thorough analysis of visual system development
 of the reef fish community.

title: Maternal gut microbiota in pregnancy dictates offspring metabolic phenotype

description: Antibiotics and dietary habits can affect the gut microbial community,
 influencing disease susceptibility. Although the influence of microbiota
 on the postnatal environment has been well documented, much less is known
 regarding the impact of gut microbiota at the embryonic stage. Here, we
 show that maternal microbiota shapes the metabolic system of offspring.
 During pregnancy, short-chain fatty acids produced by the maternal
 microbiota dictate the differentiation of neural, intestinal, and
 pancreatic cells through embryonic GPR41 and GPR43. This developmental
 process helps maintain postnatal energy homeostasis, as evidenced by the
 fact that offspring from germ-free mothers are highly susceptible to
 metabolic syndrome, even when grown under conventional conditions. Thus,
 our findings uncovered a missing link between the maternal gut environment
 and the developmental origin of metabolic syndrome.

title: Dietary stress increases the total opportunity for sexual selection and modifies selection on condition-dependent traits

description: Although it is often expected that adverse environmental conditions
 depress the expression of condition-dependent sexually-selected traits,
 the full consequences of environmental change for the action of sexual
 selection, in terms of the opportunity for total sexual selection and
 patterns of phenotypic selection, are unknown. Here we show that dietary
 stress in guppies, Poecilia reticulata, reduces the expression of several
 sexually-selected traits and increases the opportunity for total sexual
 selection (standardized variance in reproductive success) in males.
 Furthermore, our results show that dietary stress modulates the relative
 importance of precopulatory (mating success) and postcopulatory (relative
 fertilization success) sexual selection, and that the form of multivariate
 sexual selection (linear vs. nonlinear) depends on dietary regime.
 Overall, our results are consistent with a pattern of heightened
 directional selection on condition-dependent sexually-selected traits
 under environmental stress, and underscore the importance of sexual
 selection in shaping adaptation in a changing world.

title: Data from: Free-ranging dogs are capable of comprehending complex human pointing cues

description: Dogs are one of the most common species to be found as pets and have been
 subjects of human curiosity, leading to extensive research on their
 socialization with humans. One of the dominant themes in dog cognition
 pertains to their capacity of understanding and responding to human
 referential gestures. The remarkable socio-cognitive skills of pet dogs,
 while interacting with humans, is quite well established. However, studies
 regarding the free-ranging subpopulations are greatly lacking. The
 interactions of these dogs with humans are quite complex and
 multidimensional. For the first time, we tested 160 adult free-ranging
 dogs to understand their ability to follow relatively complex human
 referential gestures using dynamic and momentary distal pointing cues. We
 found that these dogs are capable of following distal pointing cues from
 humans to locate hidden food rewards. However, approximately half of the
 population tested showed a lack of tendency to participate even after
 successful familiarization with the experimental set-up. A closer
 inspection revealed anxious behavioural states of the individuals were
 responsible for such an outcome. Finally, we compared the results using
 data from an earlier study with dynamic proximal cues. We found that
 free-ranging dogs follow distal cues more accurately compared to proximal
 cue. We assume that life experiences with humans probably shape
 personalities of free-ranging dogs, which in turn influence their
 responsiveness to human communicative gestures.

title: Data from: Comparing the impact of future cropland expansion on global biodiversity and carbon storage across models and scenarios

description: Land-use change is a direct driver of biodiversity and carbon storage
 loss. Projections of future land-use often include notable expansion of
 cropland areas in response to changes in climate and food demand, although
 there are large uncertainties in results between models and scenarios.
 This study examines these uncertainties by comparing three different
 socio-economic scenarios (SSP1-3) across three models (IMAGE, GLOBIOM and
 PLUMv2). It assesses the impacts on biodiversity metrics and direct carbon
 loss from biomass and soil as a direct consequence of cropland expansion.
 Results show substantial variation between models and scenarios, with
 little overlap across all nine projections. Although SSP1 projects the
 least impact, there are still significant impacts projected. IMAGE and
 GLOBIOM project the greatest impact across carbon storage and biodiversity
 metrics due to both extent and location of cropland expansion.
 Furthermore, for all the biodiversity and carbon metrics used, there is a
 greater proportion of variance explained by model used. This demonstrates
 the importance of improving the accuracy of land-based models.
 Incorporating effects of land-use change in biodiversity impact
 assessments would also help better prioritise future protection of
 biodiverse and carbon-rich areas.

title: Not a melting pot: plant species aggregate in their non-native range

description: Aim: Plant species continue to be moved outside of their native range by
 human activities. Here, we aim at determining whether, once introduced,
 plants assimilate into native communities, or whether they aggregate, thus
 forming mosaics of native- and alien-rich communities. Alien species may
 aggregate in their non-native range due to shared habitat preferences,
 such as their tendency to establish in high-biomass, species-poor areas.
 Location: 22 herbaceous grasslands in 14 countries, mainly in the
 temperate zone. Time period: 2012 - 2016. Major taxa studied: Plants.
 Methods: We used a globally coordinated survey. Within this survey, we
 found 46 plant species, predominantly from Eurasia, for which we had
 co-occurrence data in their native and non-native range. We test for
 differences in co-occurrence patterns of 46 species, between their native
 (home) and non-native (away) range. We also tested whether species had
 similar habitat preferences, by testing for differences in total biomass
 and species richness of the patches species occupy in their native and
 non-native range. Results: We found the same species to show different
 patterns of association, depending on whether they were in their native or
 non-native range. Alien species were negatively associated with native
 species, and aggregated instead with other alien species in species-poor,
 high-biomass communities in their non-native, compared to their native
 range. Main conclusions: The strong differences between the native (home)
 and non-native (away) range in species co-occurrence patterns are evidence
 that how species associate with resident communities in their non-native
 range is not species-dependent, but rather a property of being away from
 their native range. These results thus highlight that species may undergo
 important ecological changes when introduced away from their native range.
 Overall, we show origin-dependent associations that result in novel
 communities in which alien-rich patches exist within a mosaic of
 native-dominated communities.

title: Looking for mimicry in a snake assemblage using deep learning

description: Batesian mimicry is a canonical example of evolution by natural selection,
 popularized by highly colorful species resembling unrelated models with
 astonishing precision. However, Batesian mimicry could also occur in
 inconspicuous species and rely on subtle resemblance. Although potentially
 widespread, such instances have been rarely investigated, such that the
 real frequency of Batesian mimicry has remained largely unknown. To fill
 this gap, we developed a new approach using deep learning to quantify
 visual resemblance between putative mimics and models from photographs. We
 applied this method to Western Palearctic snakes. Potential nonvenomous
 mimics were revealed by an excess of resemblance to sympatric venomous
 snakes compared to random expectations. We found that 8% of the
 non-venomous species were potential mimics, although they resembled their
 models imperfectly. This study is the first to quantify the frequency of
 Batesian mimicry in a whole community of vertebrates, and shows that even
 concealed species can act as potential models. Our approach should prove
 useful to detect mimicry in other communities, and more generally it
 highlights the benefits of deep learning for quantitative studies of
 phenotypic resemblance.

title: Data from: Trade-off between offspring mass and number: the lightest offspring bear the costs

description: Life history theory predicts a trade-off between offspring size and
 number. However, the role of intra-litter phenotypic variation in shaping
 this trade-off is often disregarded. We compared the strength of the
 relationship between litter size and mass from the perspective of the
 lightest and the heaviest yearling offspring in 110 brown bear litters in
 Sweden. We showed that the mass of the lightest yearlings decreased with
 increasing litter size, but that the mass of the heaviest yearling
 remained similar, regardless of litter size.Consistent with a conservative
 reproductive strategy, our results suggest that mothers maintained a
 stable investment in a fraction of the litter, while transferring the
 costs of a larger litter size to the remainder of the offspring. Ignoring
 intra-litter phenotypic variation may obscure our ability to detect a
 trade-off between offspring size and number.
description: This dataset includes data on brown bear yearling body masses
 from south-central Sweden, 1990-2016. Included are also litter sizes,
 maternal size and age, year of capture, and index of local population
 density. This dataset was used to conduct analyses from the journal
