Figure 1 Stewart (2026): (a) Map of sampling locations in the Andean Mountain region of Ecuador. Samples were collected in either cultivated soils with either maize or potato crops, and in surrounding non-agricultural uncultivated vegetation. Samples were collected along a climate gradient covering 1600 m in elevation across a ~500 km transect. (b) Frequency distributions of mean annual precipitation (MAP, mm/m2) and mean annual temperature (MAT, °C) at the sampling locations, colour coded by crop type. (c) Samples were collected in a 10m2 grid with nine subsamples collected at and between each vertex, and a center point. Subsamples were then homogenised into one bulk sample. The image shows an example of a potato farm in the foreground and uncultivated vegetation in the background.

(A) Maximum likelihood phylogeny based on 758 BUSCO single-copy genes of the whole yeast genomes. Genome statistics are shown for BUSCO, genome size (in Mb; orange), and GC content (in %; purple). Color stripes highlight low to higher values, ranging from light to dark color codes. (B) Heatmap of clustered log-transformed orthogroup gene counts. Yeast genera color coded based on taxonomy follows the same order as presented in the taxonomy legend. Stacked bar plot (right) indicates the number of orthogroups with gene counts.

Figure 6 Pei (2026): This conceptual model illustrates how applied biocontrol bacteria enhance pathogen inhibition by stimulating predatory protists, which subsequently increases the proportion of antibacterial genes. Pathway 1: Biocontrol bacteria stimulate the proliferation of predatory protists (Cercomonas). Under predation pressure, biocontrol bacteria (e.g., Bacillus) upregulate the production of disease-suppressive metabolites, which not only mediates their defense against protist grazing but also enhances the inhibition of pathogens (R. solanacearum). Pathway 2: Biocontrol bacteria directly secrete disease-suppressive metabolites to inhibit pathogens. The number of ‘+‘ and ‘-‘ signs indicates the significance of given effect.

Figure 1 Charvalakis (2026): Boxplots showing the nightly number of captured insects per order per light colour, averaged across trap replicates. Other taxa (H) are Blattodea, Collembola, Psocoptera, and Trichoptera combined. Each boxplot represents the median, interquartile range, and spread of the data, while grey dots indicate the mean number of insects attracted per night. Bar plots in the top right corner of each panel represent the total catch per light colour across the entire sampling period. Plotted boxes sharing the same letter are not significantly different in terms of insect capture numbers (Tukey, α = 0.05).

Figure 1 Van Leeuwen (2026): Conceptual view of the expected influence of the new littoral zones with recoupled habitats on primary producers, macroinvertebrate primary consumers and higher trophic levels in Lake Markermeer, The Netherlands. Primary production in the original lake in the pelagic zone (left food web) is mainly driven by pelagic phytoplankton. In the new littoral zones (right food web), additional contributions of benthic (macrophytes and periphyton) and terrestrial (shore plants) primary producers are expected, forming a broader base of consumers and higher trophic levels in a more complex food web. Food web based on Jin (2021).

Figure 4 Bachtsevani (2026): Cyanate facilitating reciprocal cross-feeding at pH 6.0 between “Ca. Nitrobacter laanbroekii” NHB1 and N. devaniterrae Nd1 or N. sinensis Nd2. Cyanate was supplied at 0.05 mM (A) or 0.5 mΜ (B) as an NH+4 source. NH+4, NO−,2 and NO−3 concentrations were determined for all cultures and mean values and standard errors (mostly smaller than symbol size) from triplicate cultures are plotted. Decomposition of cyanate in the abiotic control produced <3.8 μM NH+4 during the period of incubation.

Figure 7 Zhou (2026): Conceptual diagram of the effects of grazing exclusion on the stocks of soil organic carbon fractions across two soil depths. Soil organic carbon (SOC) fractions include particulate organic carbon (POC) and mineral-associated organic carbon (MAOC). The percentage changes in SOC fractions represent the variations of the two grazing exclusion treatments relative to grazing across 0–30 cm soil depth. For the other predictor variables, the percentages represent the mean changes of the two grazing exclusion treatments relative to grazing, calculated separately for the 0–10 cm and 10–30 cm soil depths. Orange arrows denote positive effects, while blue arrows indicate negative effects. Ox:Hy ratios, oxidative-to-hydrolytic enzymes ratios.

Figure 1 Magnússon (2026): Experimental design and monitoring. Adapted after Magnússon et al. (2024). (a) Location of sites in the vicinity of Longyearbyen and Ny-Ålesund. Basemaps from www.toposvalbard.npolar.no. (b) At each site, we set out six or seven replicates per treatment, consisting of a Control (C) treatment and three Irrigation (I, ES, LS) treatments with different timing of rainfall events. (c) Each plot was a 4 m diameter circle, with fixed measurement points around the perimeter and in the centre, in which soil moisture (SM) was monitored. Vegetation composition, NDVI and vegetation height (VH) were measured in a smaller grid within the plot. Measurements of senescence and leaf sampling for specific leaf area (SLA) were carried out in the area in between the measurement points. (d) Timeline of the experiment and measurements in the plots around Longyearbyen. (e) Timeline of the experiment and measurements in the plots around Ny-Ålesund. For (d and e), Control and Irrigation (‘Legacy Experiment’) plots were set out in 2022, while Early-summer and Late-summer irrigation (‘Timing Experiment”) plots were added in 2023. Duration of plot monitoring is indicated by horizontal lines with colours corresponding to the treatments in (b). All plots were monitored until late summer 2024.

Figure 1 O'Malley (2026): Yields varied substantially across the LegacyNet sites. (A) The locations of the 26 LegacyNet sites, indicated by inverted yellow triangles (see data S1 for the site location details and ID codes). (B) The yield per growing season (t ha−1) based on plot-level measurements for each site are shown in boxplots that are grouped by mixtures (blue; 29 plots per site) and monocultures (gray; 18 plots per site), at the moderate nitrogen fertilizer level. The average yield of the six-species equiproportional mixture plots (three plots per site) is shown as a magenta triangle. The average yield of the monoculture plots from each functional group is highlighted with a circle (green for grass, orange for legume, and light blue for herb; six monoculture plots per functional group per site). The average yield of the high N grass monoculture (five plots per site) is shown by a red horizontal line. Sites are arranged on the x axis in order of decreasing median yield. The center line represents the median, box limits are upper and lower quartiles, and whiskers extend to the minimum and maximum of nonoutlier values.

Figure 3 Delavaux (2026): Major traits hypothesized to impact the mutualist filter. A framework synthesizing mutualism traits hypothesized to impact the strength of the mutualist filter. Plant host traits include specificity, dependency, and multiple mutualists; mutualist traits include dispersal limitation, specificity, and dependency. Finally, species introductions may mediate the filter, with differing effects on the mainland relative to islands. An example within the mycorrhizal symbiosis contrasting arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) mutualisms is given in the dark gray boxes. Although EM mutualisms are relatively stronger in three out of five traits predicted to increase the mutualist filter, research shows that AM plant species experience a stronger filter, likely due to the overriding effect of dispersal limitation.
