Abstract Sustainable provision of critical ecosystem services in drylands is reliant on their stability under anthropogenic disturbances. Livestock grazing and shrub encroachment are the primary drivers disturbance that impact biodiversity production dynamics. However, effects at multiple scales, particularly following transition from grass‐dominated to shrub‐encroached drylands, still largely unexplored. Here, we conducted comparable sheep‐grazing experiments two types (grass‐dominated vs. grasslands) Mongolia Plateau explore scales. We examined how affected temporal aboveground biomass herbaceous communities both grasslands, through potential mechanisms: insurance changes population‐level individual species. found an increase sheep intensity had significant negative by decreasing species asynchrony spatial but it no population stability, consequently leading reductions community grasslands. grazing‐increased cancelled out grazing‐decreased contributing Likely, because grazing‐induced relative abundance dominant were more noticeable grasslands than Moreover, was directly correlated increases not despite positive relationships between drylands.

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.

However, changes in over past few decades risk future loss under ongoing climate change are unclear.

Abstract It is well known that biodiversity positively affects ecosystem functioning, leading to enhanced stability. However, this knowledge mainly based on analyses using single functions, while studies focusing the stability of multifunctionality (EMF) are rare. Taking advantage a long‐term grassland experiment, we studied effect plant diversity (1–60 species) EMF over 5 years, its temporal stability, as multifunctional resistance and resilience 2‐year drought event. Using split‐plot treatments, further tested whether shared history plants soil influences relationships. We calculated functions related higher‐trophic levels. Plant in all strengthened study period. Moreover, increased fostered reoccurring events. Old communities with showed stronger diversity–multifunctionality relationship higher than younger without histories. Our results highlight importance old biodiverse for extreme climate events world increasingly threatened by global change.

Abstract Aim Understanding the biodiversity–stability relationship has become a central issue in ecology and conservation biology. Although stabilizing effects of tree species diversity on ecosystem productivity are well recorded small local communities, they remain poorly understood across scales (from to larger spatial scales). This study evaluates from large temperate forest region, considering range environmental conditions heterogeneity. Location North‐eastern China ( c . 700,000 km 2 ). Time period 2005–2017. Major taxa studied Woody plants. Methods We define stability as temporal invariability biomass productivity. Regional metacommunities representing were developed by aggregating multiple sets field plots. Simple regression analysis was used test relationships metacommunities. Piecewise structural equation modelling then disentangle abiotic variables at scales. Multiple mixed‐effects models determine relative contribution individual predictive Results found that (alpha diversity) positively related communities stability), whereas turnover space (beta asynchronous dynamics among (spatial asynchrony), regardless whether factors considered or not. also heterogeneity affected The effect asynchrony gamma greater than alpha stability.

Abstract Weather extremes like droughts and heat waves are becoming increasingly frequent worldwide, with severe consequences for agricultural production food security. Although the effects of such events on major crops is well-documented, response a larger pool unknown potential crop diversity to buffer outputs against weather remains untested. Here, we evaluate whether increasing portfolios at country level confers greater resistance country’s overall yield revenues losses high temperatures. To do this, use 58 years annual data weather, yields 109 in 127 countries. We spatial distribution each their cropping cycle determine exposure events. find that growing within countries reduces negative impacts temperatures outputs. For drought, our results suggest effect explained not only by itself, but also sensitivity most abundant (in terms harvested areas) this extreme. Countries dedicating more land minor, drought-tolerant reduce average country-scale show drought.
