Abstract Temporal stability of primary productivity is the key to stable provisioning ecosystem services human beings. Yet, effects various global changes on grassland remain ambiguous. Here, we conducted a comprehensive meta‐analysis based 1070 multi‐year paired observations from 173 studies, examine impacts productivity, community and plant diversity grasslands scale. The change drivers include nitrogen (N) addition, phosphorus (P) N P precipitation increase, decrease, elevated CO 2 warming. Global generally had stronger than temporal stability, except for changes. Community was reduced by addition but increased increase remained unchanged under In species richness decreased decrease. At functional group level, grasses' enhanced forbs' stability.

Understanding the effects of diversity on ecosystem stability in context global change has become an important goal recent ecological research.

Short-term experimental studies provided evidence that plant diversity increases ecosystem resilience and resistance to drought events, suggesting serve as a nature-based solution address climate change. However, it remains unclear whether the effects of are momentary or still hold over long term in natural forests ensure sustainability carbon sinks. By analyzing 57 years inventory data from dryland Canada, we show productivity decreased at an average rate 1.3% per decade, concert with temporally increasing temperature decreasing water availability. Increasing functional trait its minimum (monocultures) maximum value increased by 13%. Our results demonstrate potential role tree alleviating change impacts on forests. While recognizing mitigation (e.g., planting trees) can only be partial solutions, their long-term (decadal) efficacy improved enhancing across forest community.

Abstract The synthesis of a large body evidence from field experiments suggests more diverse plant communities are productive as well resistant to the effects climatic extremes like drought. However, this view is strongly based on data grasslands due limited empirical tree diversity experiments.

Across number years, species were significantly positively related; however, slope switched negative year Net increased through time, with complementarity making greater contributions net effect than selection effects.

ABSTRACT Maintaining the stability of ecosystems is critical for supporting essential ecosystem services over time. However, our understanding contribution diverse biotic and abiotic factors to this in wetlands remains limited. Here, we combined data from a field vegetation survey 725 herbaceous wetland sites China with remote sensing information Enhanced Vegetation Index (EVI) 2010 2020 explore temporal primary productivity. We found that plant species richness directly contributed on national scale, but differed among climate zones, hydrological regimes, types. In addition, many factors, including soil properties, geographical location, also stability. Piecewise structural equation modeling identified pH, total nitrogen, organic carbon, emerged as modulating stability, both indirectly by affecting type. Higher carbon were related higher peatlands less so coastal inland marshes.

Abstract The relationship between biodiversity and ecosystem functioning strengthens with age. However, the interplay plant diversity - Glomeromycotinian arbuscular mycorrhizal fungi (AMF) community assembly has not yet been scrutinized in this context, despite AMF’s role survival niche exploration. We study development of AMF communities by disentangling soil- plant-driven effects from calendar year effects. Within a long-term grassland experiment, pre-existing varying were re-established as split plots combinations common soil histories: neither nor history, only but no both history. found that bulk primarily shaped additional history had little effect. Further, steepness did strengthen over time, evenness increased Specialisation towards species was low throughout, giving indication specialising or diversifying time. potential mediators variation microbial biomass time hence drivers relationships low. Our results suggest processes may be key for build-up community-specific likely feedback on productivity, plant-available pool itself does explain strengthening
