title: Data from: Extreme drought stress shifts net facilitation to neutral interactions between shrubs and sub-canopy plants in an arid desert

description: The stress gradient hypothesis (SGH) predicts that the importance or
 intensity of competition and facilitation will change inversely along
 abiotic stress gradients. It was originally postulated that increasing
 environmental stress can induce a monotonic increase in facilitation.
 However, more recent models predicted that the relationship between
 severity and interaction exhibits a hump-shaped pattern, in which positive
 interactions prevail under moderate stress but decline at the extreme ends
 of stress gradients. In the present study, we conducted a field experiment
 along a temporal rainfall gradient for five consecutive years, in order to
 investigate interactions in a shrub-herbaceous plant community at the
 southern edge of the Badain Jaran Desert, and, more specifically,
 investigated the effects of Calligonum mongolicum, a dominant shrub
 species, on both abiotic environmental variables and the performance of
 sub-canopy plant species. We found that shrubs can improve sub-canopy
 water regimes, soil properties, plant biomass, density, cover, and
 richness and, more importantly, that the positive effect of shrubs on
 sub-canopy soil moisture during the summer diminishes as rainfall
 decreases, a pattern that partly explains the collapse of the positive
 interaction between shrubs and their understory plants. These results
 provide empirical evidence that the positive effect of shrubs on
 understory plant communities in extreme arid environments may decline and
 become neutral with increasing drought stress.

title: Data from: Resident species with larger size metrics do not recruit more offspring from the seed bank in old-field meadow vegetation

description: 1. According to the traditional ‘Size Advantage’ (SA) hypothesis, plant
 species with larger body size are expected to be more successful when
 competition is intense, i.e. within severely crowded vegetation. Recent
 studies in old-field habitats, however, have shown that those species with
 greater numerical abundance as resident plants generally have a relatively
 small minimum reproductive threshold size (MIN), not a relatively large
 maximum potential body size (MAX). 2. In this study, we test for a size
 advantage in terms of species abundance representation in the soil seed
 bank, and we extend the SA hypothesis to include two additional size
 metrics: leaf size and seed size. Specifically, we ask, for resident
 species within a crowded old-field meadow: is larger seed size, leaf size,
 and/or body size associated with greater reproductive / recruitment
 success (i.e. number of germinable seeds within — and establishing plants
 emerging from — the soil seed bank)? We collected soil cores for a
 greenhouse experiment to record relative species abundances of germinable
 seeds in the seed bank, and we used a field experiment to record local
 abundances of species emerging from the resident seed bank within denuded
 plant neighbourhoods over three subsequent field seasons. 3. We found no
 general support for the SA hypothesis involving any of the size metrics,
 and none of the latter was a strong predictor of the number of germinable
 seeds emerging from soil cores in the greenhouse experiment. However, for
 species establishing in the field experiment from the seed bank over the
 three-year survey period, more abundant species in years 2 and 3 tended to
 be those with smaller MIN, and thus smaller MAX. In addition, within more
 crowded neighbourhoods, representation of reproductive plants was
 generally greater for species with relatively small MIN (and hence small
 MAX). 4. Synthesis. Our results extend support for the ‘Reproductive
 Economy Advantage’ hypothesis in old field habitats, to include not just
 established, largely undisturbed vegetation, but also very early stages of
 recruitment from seed within locally crowded plant neighbourhoods.
 Specifically, more successful species here are not those with relatively
 large potential body size (MAX); they are species capable of producing at
 least some offspring despite severe body size suppression, because they
 have a relatively small MIN.

title: Data from: Growth strategy, phylogeny and stoichiometry determine the allelopathic potential of native and non-native plants

description: Secondary compounds can contribute to the success of non-native plant
 species if they reduce damage by native herbivores or inhibit the growth
 of native plant competitors. However, there is opposing evidence on
 whether the secondary compounds of non-native plant species are stronger
 than those of natives. This may be explained by other factors, besides
 plant origin, that affect the potential of plant secondary compounds. We
 tested how plant origin, phylogeny, growth strategy and stoichiometry
 affected the allelopathic potential of 34 aquatic plants. The allelopathic
 potential was quantified using bioassays with the cyanobacterium
 Dolichospermum flos-aquae. The allelopathic potential showed a strong
 phylogenetic signal, but was similar for native and non-native species.
 Growth strategy was important, and emergent plants had twice the
 allelopathic potential as compared to submerged plants. Furthermore, the
 allelopathic potential was positively correlated to the foliar
 carbon-to-phosphorus (C:P) and total phenolic content. We conclude that
 eudicot plant species with an emergent growth strategy and high plant C:P
 ratio exhibit a high allelopathic potential. Unless non-native plant
 species match this profile, they generally have a similar allelopathic
 potential as natives.

title: Data from: Copy if dissatisfied, innovate if not: contrasting egg-laying decision making in an insect

description: The use of conspecific cues as social information in decision making is
 widespread among animals; but, because this social information is
 indirect, it is error-prone. During resource acquisition, conspecific cues
 also indicate the presence of competitors; therefore, decision makers are
 expected to utilize direct information from resources and modify their
 responses to social information accordingly. Here, we show that, in a
 non-social insect, unattractive egg-laying resources alter the behavioural
 response to conspecific cues from avoidance to preference, leading to
 resource sharing. Females of the adzuki bean beetle Callosobruchus
 chinensis avoid laying eggs onto beans that already have conspecific eggs.
 However, when we provided females with bean-sized clean glass beads with
 and without conspecific eggs, the females preferred to add their eggs onto
 the beads with eggs. The glass beads, once coated with water extracts of
 adzuki beans, enabled the females to behave as if they were provided with
 the beans: the females preferred bean-odoured glass beads to clean glass
 beads and they avoided the substrates with eggs. When females are provided
 with unattractive egg-laying substrates only, joining behaviour (i.e.
 copying) might be advantageous, as it takes advantage of information about
 positive attributes of the substrate that the focal animal might have
 missed. Our results suggest that given only unsatisfactory options, the
 benefits of copying outweigh the costs of resource competition. Our study
 highlights the importance of integrating multiple information sources in
 animal decision making.

title: Data from: Warming reduces the growth and diversity of biological soil crusts in a semi-arid environment: implications for ecosystem structure and functioning

description: Biological soil crusts (BSCs) are key biotic components of dryland
 ecosystems worldwide that control many functional processes, including
 carbon and nitrogen cycling, soil stabilization, and infiltration.
 Regardless of their ecological importance and prevalence in drylands, very
 few studies have explicitly evaluated how climate change will affect the
 structure and composition of BSCs, and the functioning of their
 constituents. Using a manipulative experiment conducted over three years
 in a semi-arid site from central Spain, we evaluated how the composition,
 structure and performance of lichen-dominated BSCs respond to a 2.4 ºC
 increase in temperature, and to a ~ 30% reduction of total annual
 rainfall. In areas with well-developed BSCs, warming promoted a
 significant decrease in the richness and diversity of the whole BSC
 community. This was accompanied by important compositional changes, as the
 cover of lichens suffered a substantial decrease with warming (from 70% to
 40% on average), while that of mosses increased slightly (from 0.3% to 7%
 on average). The physiological performance of the BSC community, evaluated
 using chlorophyll fluorescence, increased with warming during the first
 year of the experiment, but did not respond to rainfall reduction. Our
 results indicate that ongoing climate change will strongly affect the
 diversity and composition of BSC communities, as well as their recovery
 after disturbances. The expected changes in richness and composition under
 warming could reduce or even reverse the positive effects of BSCs on
 important soil processes. Thus, these changes are likely to promote an
 overall reduction in ecosystem processes that sustain and control nutrient
 cycling, soil stabilization and water dynamics.

title: Data from: Field to a forest: patterns of forest recovery following shifting cultivation in the eastern Himalaya

description: The patterns of vegetation recovery in shifting cultivation landscapes
 that undergo a cycle of clearing, cultivation and forest regeneration are
 not well understood in Asian tropical forests. We determined forest
 recovery patterns by comparing species composition, richness and forest
 structure in early and late fallows formed following shifting cultivation
 and in an uncut forest site in a mid-elevation subtropical forest in the
 Indian Eastern Himalaya. We also examined changes in functional traits of
 tree species to understand recovery processes with succession. Tree
 species richness in the 12, 25 and 50-year old sites was 37%, 54% and 82%
 the value of the richness in uncut forest, respectively, while basal area
 was 33%, 25% and 41% of the value in uncut forest, respectively. Species
 composition recovery, however, was low; with even the oldest fallow
 (50-year fallow) being less than 50% similar to uncut forest in terms of
 composition. Successional sites that recover over long periods may differ
 compositionally from uncut forest within a shifting cultivation landscape
 as these forests are often prone to other anthropogenic disturbances.
 Functional trait analysis revealed that early fallows were colonized by
 tree species that are animal-dispersed, insect-pollinated with small
 fruits and seeds, whereas uncut forest and late successional forests were
 dominated by species that were tall, self-dispersed, wind-pollinated and
 of high wood density that are dominant mature forest species in the
 Himalaya. These results are in contrast with the patterns in functional
 traits of tree species in successional sites from the Neotropics. This
 points to the importance of site-specificity in succession following
 shifting cultivation.

 and regeneration) was collected from different-aged successional sites
 formed following shifting cultivation and uncut forest sites. Data was
 collected from two replicate sites each from 2 year, 12 year, 25 year and
 50 year old successional sites and two uncut forest sites. Trees (diameter
 at breast height, dbh&gt;=3 cm) were inventoried and identified to species
 or genus level in twelve 7 m radius plots located 25 m from each other on
 alternating sides of a 250-m transect. We enumerated the regeneration
 comprising of seedlings (height&lt;=25 cm) and saplings (height&gt;25 cm
 & &lt;=100 cm) of tree species in each of the four successional stages
 and the uncut forest sites in 1-m and 3-m radius nested within the 7-m
 radius plots, respectively. Detailed methods are provided in the methods
 section of the main article.

title: Data from: Choice in a floral marketplace: the role of complexity in bumble bee decision-making

description: Animals have evolved in complex, heterogeneous environments. Thus,
 decision-making behavior is likely affected by a diversity of co-occurring
 community-level traits. Here, we investigate how three co-occurring traits
 of floral communities - the number of flower types, reliability that
 flowers are associated with a reward, and signal complexity of flowers -
 affect bumble bee (Bombus impatiens) decision-making. We used arrays of
 artificial flowers in a full factorial experimental design to assess
 floral selectivity (preference and constancy), foraging efficiency, and
 decision latency in foraging bumble bees. We find that our environmental
 traits uniquely affect each of these behavioral variables, revealing the
 intricate, yet biologically significant ways that co-occurring
 environmental traits can affect behavior. Floral selectivity, but not
 foraging efficiency, is increased by a greater number of choices. Decision
 latency is greatest when bees are inexperienced foraging in environments
 with high choice number. Collectively taken, we argue that these results
 suggest a cost to deciding among many choices, which promotes choice
 fidelity when many options are present. We suggest that these results have
 implications for theory on decision-making and selection in biological
 markets, while demonstrating the importance of studying interactions
 between naturally co-occurring traits.

title: Data from: A hidden cost of migration? Innate immune function versus antioxidant defense

description: Migration is energetically demanding and physiologically challenging.
 Migrating birds, for example, need to boost their antioxidant defenses to
 defeat the pro-oxidants produced during high energetic activity. The
 enhanced antioxidant defense possibly withdraws limited resources (e.g.
 energy or micronutrients) from other physiological functions, such as
 immune defense. Such a trade-off might not occur outside the migration
 seasons or in resident individuals. Here, we investigate if there is a
 negative relationship between innate immune function and antioxidant
 defense by sampling both migrating and resident blackbirds (Turdus merula)
 at the same location during the same period of the annual cycle. We show
 that in migrating blackbirds microbial killing capacity (BKA), an
 integrative measure of baseline innate immune function, was negatively
 correlated with total non-enzymatic antioxidant capacity. In contrast, in
 resident conspecifics, sampled at the same time and location, these two
 physiological measures were not correlated. This suggests that migrating
 birds trade off innate immune function and antioxidant defense.
 Furthermore, and likely a consequence of this trade-off, in migrant
 blackbirds BKA was positively correlated with oxidative damage to lipids.
 In resident blackbirds BKA and degree of lipid oxidation were
 uncorrelated. The mechanism and currencies of the supposed trade-off are
 currently unknown, but energetic investments or micronutrients are likely
 candidates. Future experimental studies could provide more conclusive
 evidence for this trade-off; yet, our results open up a new level of
 thinking about the physiological costs of migration.

title: Data from: Tree species richness increases ecosystem carbon storage in subtropical forests

description: Forest ecosystems are an integral component of the global carbon cycle as
 they take up and release large amounts of C in short time (C flux) or
 accumulate it over longer time (C stock). However, there remains
 uncertainty about whether and in which direction C fluxes and in
 particular C stocks may differ between forests of high vs. low species
 richness. Based on a comprehensive dataset derived from field-based
 measurements, we tested the effect of species richness (3–20 tree species)
 and stand age (22–116 years) on six compartments of above- and belowground
 C stocks and four components of C fluxes in subtropical forests in
 south-east China. Across forest stands, total C stock was 149 ± 12 Mg ha-1
 with richness explaining 28.5% and age explaining 29.4% of variation in
 this measure. Species-rich stands had higher C stocks and fluxes than
 stands with low richness; and, in addition, old stands had higher C stocks
 than young ones. Overall, for each additional tree species the total C
 stock increased by 6.4%. Our results provide comprehensive evidence for
 diversity-mediated above- and belowground C sequestration in species-rich
 subtropical forests in south-east China. Therefore, afforestation policies
 in this region and elsewhere should consider a change from the current
 focus on monocultures to multi-species plantations to increase C fixation
 and thus slow increasing atmospheric CO2 concentrations and global
 warming.
