Abstract There is increasing evidence that mixed‐species forests can provide multiple ecosystem services at a higher level than their monospecific counterparts. However, most studies concerning tree diversity and functioning relationships use data from forest inventories (under noncontrolled conditions) or very young plantation experiments. Here, we investigated temporal dynamics of diversity–productivity diversity–stability in the oldest tropical experiment. Sardinilla was established Panama 2001, with 22 plots form gradient native species richness one‐, two‐, three‐ five‐species communities. Using annual describing diameters heights, calculated basal area increment as proxy productivity. We combined neighbourhood‐ community‐level analyses tested effects both structural on productivity its stability. General patterns were consistent across scales indicating tree–tree interactions neighbourhoods drive observed effects. From 2006 to 2016, mean overyielding (higher mixtures monocultures) 25%–30% two‐ three‐species 50% stands. Tree neighbourhood enhanced community but effect stronger increased over time, whereas declined. Temporal stability via two principle mechanisms: asynchronous responses environmental variability overyielding. Overyielding highest during strong El Niño‐related drought. Overall, positive predominated, levels diversity. These results new insights into mixing diverse, plantations highlight importance for our understanding complex between diversity, Under climate change, may high production.

Tree diversity improves forest productivity Experimental studies in grasslands have shown that the loss of species has negative consequences for ecosystem functioning. Is same true forests? Huang et al. report first results from a large biodiversity experiment subtropical China. The study combines many replicates, realistic tree densities, and plot sizes with wide range richness levels. After 8 years experiment, findings suggest strong positive effects on carbon accumulation. Thus, changing monocultures to more mixed forests could benefit both restoration mitigation climate change.

Abstract A rich body of knowledge links biodiversity to ecosystem functioning (BEF), but it is primarily focused on small scales. We review the current theory and identify six expectations for scale dependence in BEF relationship: (1) a nonlinear change slope relationship with spatial scale; (2) scale‐dependent between stability extent; (3) coexistence within among sites will result positive at larger scales; (4) temporal autocorrelation environmental variability affects species turnover thus (5) connectivity metacommunities generates relationships by affecting population synchrony local regional (6) scaling food web structure diversity generate functioning. suggest directions synthesis that combine approaches metaecosystem metacommunity ecology integrate cross‐scale feedbacks. Tests this may remote sensing generation networked experiments assess effects multiple also show how anthropogenic land cover alter relationship.

Microorganisms drive several processes needed for robust plant growth and health. Harnessing microbial functions is thus key to productive sustainable food production. Molecular methods have led a greater understanding of the soil microbiome composition. However, translating species or gene composition into functionality remains challenge. Community ecology concepts such as biodiversity–ecosystem functioning framework may help predict assembly function plant-associated microbiomes. Higher diversity can increase number resilience plant-beneficial that be coexpressed unlock expression traits are hard obtain from any in isolation. We combine well-established community with molecular microbiology workable enable us enhance promote global change context.

Forest ecosystems are an integral component of the global carbon cycle as they take up and release large amounts C over short time periods (C flux) or accumulate it longer stock). However, there remains uncertainty about whether in which direction fluxes particular stocks may differ between forests high versus low species richness.

Multispecies tree planting has long been applied in forestry and landscape restoration the hope of providing better timber production ecosystem services; however, a systematic assessment its effectiveness is lacking. We compiled global dataset matched single-species multispecies plantations to evaluate impact on stand growth. Average height, diameter at breast aboveground biomass were 5.4, 6.8, 25.5% higher, respectively, stands compared with stands. These positive effects mainly result interspecific complementarity modulated by differences leaf morphology life span, age, density, temperature. Our results have implications for designing afforestation reforestation strategies bridging experimental studies biodiversity-ecosystem functioning relationships real-world practices.

Humans modify ecosystems and biodiversity worldwide, with negative consequences for ecosystem functioning. Promoting plant diversity is increasingly suggested as a mitigation strategy. However, our mechanistic understanding of how affects the heterotrophic consumer communities remains limited. Here, we disentangle relative importance key components drivers herbivore, predator, parasitoid species richness in experimental forests grasslands. We find that effects on are consistently positive mediated by elevated structural functional communities. The these differs across trophic levels ecosystems, cautioning against ignoring fundamental ecological complexity effects. Importantly, higher trophic-level many cases modifications abundances. In light recently reported drastic declines insect abundances, study identifies important pathways connecting ecosystems.
