Research on biodiversity–ecosystem functioning relationships tends to focus on single trophic groups. This analysis of two biodiversity experiments, representing forests and grasslands, shows that plant diversity promotes ecosystem multifunctionality not only directly, but also by enhancing the diversity of other trophic levels.

Identifying pairs of genotypes that perform better in mixture than monoculture is important for increasing crop yields. Using the model species Arabidopsis thaliana, this study provides a proof of principle of how such beneficial genotype pairs could be found using genome-wide association studies.

To assess drivers underpinning biogeographic patterns of leaf nitrogen and phosphorus stoichiometry, this study used a global dataset of leaf nitrogen and phosphorus concentrations of 3,625 species from 7,549 sites. They found strong within-species variation related to environmental gradients, challenging the idea of a fixed biogeochemical niche.

Vaccination mandates can increase vaccine uptake, but might cause unintended psychological effects with social and political consequences. In this Review, Schmid et al. present a toolbox of complementary and alternative interventions informed by psychological science to tackle vaccine hesitancy.

Species-rich plant communities often have higher productivity than monocultures. Here, the authors analyse biodiversity-ecosystem functioning experiments in grasslands and forests and find that the biodiversity effects on community productivity strengthen over time thanks to shifts in contributions of species with different resource acquisition traits.

A multi-ancestry genome-wide association meta-analysis of kidney cancer identifies 63 regions associated with disease susceptibility including one locus that was associated with increased risk in individuals with African ancestry.

Whether plant epigenetic variation is subject to selection and contributes to adaptation is under debate. Here, the authors compare DNA methylation and phenotypes of Arabidopsis lines subject to simulated selection and their nearly isogenic ancestors and provide evidence that epigenetic variation contributes to adaptive responses.

Examining drivers of the latitudinal biodiversity gradient in a global database of local tree species richness, the authors show that co-limitation by multiple environmental and anthropogenic factors causes steeper increases in richness with latitude in tropical versus temperate and boreal zones.

Transcriptional regulator Rbpj is involved in T-helper subset differentiation. Here the authors show that expression of Rbpj in regulatory T cells is required to both regulate T_H2 responses and regulate T_reg T_H2 differentiation potential.

Explainable Artificial Intelligence can improve conservation decisions by revealing hidden insights to where human impacts on biodiversity are greatest. In this investigation of freshwater fish in Switzerland, around 90% of potentially habitable areas were negatively impacted human influences - these areas form the species’ “shadow distribution”.

Global spatiotemporal patterns of plant diversification are unclear. Here, the authors use a genus-level phylogeny and global distribution data for 14,244 flowering plant genera, finding a negative correlation between spatial patterns of diversification and genus diversity.

Biodiversity-ecosystem functioning relationships may vary with climate. Here, the authors study relationships of plant and soil microbial diversity with soil nutrient multifunctionality in 130 dryland sites in China, finding a shift towards greater importance of soil microbial diversity in arid conditions.

Alternative stable states in forests have implications for the biosphere. Here, the authors combine forest biodiversity observations and simulations revealing that leaf types across temperate regions of the NH follow a bimodal distribution suggesting signatures of alternative forest states.

Angelo Fasce et al. conducted a systematic literature review and applied natural language processing methods to develop a taxonomy that relates anti-vaccination arguments to their psychological roots.

Biodiversity often increases the functioning and productivity of ecosystems or communities. This work shows that such a positive diversity effect, namely overyielding in mixtures of two divergent Arabidopsis thaliana genotypes, can be genetically mapped and resolved to a single gene.

Physical complementarity among trees in the use of vertical space increases productivity due to species-specific differences and plasticity in crown architecture.

A biodiversity–ecosystem functioning experiment in a young subtropical forest shows that, at high species richness, directed but not random species loss leads to pronounced productivity decrease.

Trees often associate with mycorrhizal fungi, arbuscular mycorrhizal (AM) or ectomycorrhizal (ECM) fungi. Luo et al. analyze 74,563 forest plots across the contiguous USA, showing that forests with mixed AM and ECM tree species are more productive than when dominated by AM or ECM tree species.

Using data from the BEF-China tree diversity experiment, the authors demonstrate that the diversity of arthropods is higher in plots with higher tree diversity and that the suppression of herbivores by enemy arthropods could be a potential mechanism through which higher tree diversity promotes productivity.

Plant diversity stabilizes grassland soil temperature by boosting soil organic carbon and increasing plant leaf area, according to an 18-year plant diversity experiment.

In a long-running forest biodiversity experiment in China, the authors ask which measures of tree functional trait diversity impact productivity as forests develop. While productivity increased with community-weighted mean trait values early on, after 7 years productivity was significantly increased in plots with higher functional diversity.
