The relationship between biodiversity and ecosystem functions (BEFs) has attracted great interest. Studies on BEF have so far focused the average trend of function as species diversity increases. A tantalizing but rarely addressed question is why large variations in are often observed across systems with similar diversity, likely obscuring BEFs. Here we use a multi-trophic food web model combination empirical data to examine relationships richness variation (VEFs) including biomass, metabolism, decomposition, primary secondary production. We then probe mechanisms underlying these relationships, focusing role trophic interactions. While our results reinforce previously documented positive found that exhibit significant within each level magnitude this displays hump-shaped richness. Our analyses demonstrate VEFs reduced when consumer increases through elevated nonlinearity interactions, and/or basal such producers decomposers decreases. This explanation supported by 34-year time series from Gulf Riga ecosystem. work suggests loss may not only result decline, also reduce predictability generating greater variability among ecosystems. It thus helps reconcile debate generality disentangle drivers stability. interactions their strengths mediated functional responses shaping warrants further investigations better incorporation into biodiversity-ecosystem functioning research.

Understanding the effects of diversity on ecosystem stability in context global change has become an important goal recent ecological research. However, at multiple scales and trophic levels across environmental gradients remain unclear. Here, we conducted a field survey α-, β-, γ-diversity plants soil biota (bacteria, fungi, nematodes) estimated temporal normalized difference vegetation index (NDVI) 132 plots Mongolian Plateau. After climate variables were controlled for, both α- β-diversity (mainly via together with precipitation explained most variation stability.

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. Here we report relationship between and productivity over 10 years in experiment established 2005 that was then affected by 2018 mega‐drought central Europe. 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. Complementarity clearly positive three‐ five‐species mixtures before drought (2012–2016) but found decrease Selection 2016 remained two‐, three‐, mixtures. survival Norway spruce ( Picea abies ) plummeted response drought, found. Taken together, our findings suggest per se may not buffer against impacts extreme composition tolerance (i.e., identity) will be important determinants community prevalence increases.

Abstract Biodiversity is considered important to the mitigation of global change impacts on ecosystem multifunctionality in terrestrial ecosystems. However, potential mechanisms through which biodiversity maintains under remain unclear. We grew 132 plant communities with two levels diversity, crossed treatments based 10 factors (nitrogen deposition, soil salinity, drought, invasion, simulated grazing, oil pollution, plastics antibiotics heavy metal and pesticide pollution). All negatively impacted multifunctionality, but negative were stronger high compared low diversity communities. explored for this unexpected result, finding that inhibition selection effects (i.e., species associated functioning) contributed sensitivity change. Specifically, decreased abundance novel functional plants legumes) not The also mediated by increased relative fungal pathogens (identified from metabarcoding samples) their relationship plants. Taken together, our experiment highlights importance protecting legumes, managing pathogens, maintenance face complex

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

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. These findings enhance ability forecast how may respond future environmental changes biodiversity loss can inform policy decisions

Long-term research in grassland biodiversity experiments has provided empirical evidence that ecological and evolutionary processes are intertwined determining both biodiversity–ecosystem functioning (BEF) biodiversity–stability relationships. Focusing on plant diversity, we hypothesize multifunctional stability is highest high-diversity communities relationships increase over time due to a variety of forms complementarity including the interaction with other biota above below ground. We introduce multiple-mechanisms hypothesis suggesting it not an individual mechanism drives long-term effects ecosystem but several produce increasingly positive effects. The following six mechanisms important. Low-diversity accumulate more antagonists (1), use resources less efficiently have open, leaky nutrient cycles (2). Conversely, support greater diversity activity beneficial partners across trophic levels (3); diversify their traits space, within species, optimize temporal (intra- interannual) spatial (4), create stable microclimate (5), foster higher top-down control aboveground belowground herbivores by predators (6). In line observation different species play unique roles ecosystems dynamic multifaceted, particular contributing most performance diverse might differ functions, years, locations, environmental change scenarios. This indicates "between-context insurance" or "across-context complementarity" mechanisms. examples will be conducted test our hypotheses which inspire additional work.
