Mixed-species plantations are increasingly recognized for their potential to maintain forest biodiversity and soil health; however, a comprehensive assessment of global effectiveness is lacking. To fill this knowledge gap, we conducted meta-analysis 7,045 paired observations between mixed-species monoculture plantations, derived from 311 studies across diverse ecosystems worldwide. Our results show that significantly increased understory plant biomass, cover, species richness by 32.6%, 55.4%, 32.2%, respectively, compared monocultures. Furthermore, the Shannon Pielou diversity indices 28.2% 8.6%, Simpson index 9.6%. When shrub herbaceous were considered separately, mixing had positive effects on but no effect diversity. Moreover, markedly improved physical chemical properties These improvements include increases in nutrient content (9.6 17.8%) availability (14.7 33.5%), microbial biomass (17.2 28.8%), carbon sequestration (7.2 19.9%). enhancements particularly pronounced included legumes. findings reveal benefits influenced climatic conditions, geographic location, stand age, with most substantial observed temperate regions mature stands. This study underscores critical role promoting sustainable management mitigating ecological limitations

Plant functional traits hold the potential to greatly improve understanding and prediction of climate impacts on ecosystems carbon cycle feedback change. Traits are commonly used place species along a global conservative-acquisitive trade-off, yet how if trade-offs scale up mediate community ecosystem fluxes is largely unknown. Here, we combine trait datasets multibiome forest water at species, community, ecosystem-levels quantify scaling tradeoff between maximum flux sensitivity vapor pressure deficit. We find strong trade-off scale, which weakens modestly disappears scale. Functional traits, particularly plant transport (hydraulic) strongly associated with key dimensions scales, highlighting that composition appears influence dynamics. Our findings provide foundation for improving models by revealing i) hydraulic most community- dynamics ii) assembly likely need be considered explicitly, as they give rise ecosystem-level differ substantially from identified species-level.

Amazon rainforests are critical for providing a wide range of ecosystem services. In the Southeastern Peruvian Amazon; however, goldmining activities causing severe soil degradation and forest loss. We analyzed aboveground biomass (AGB), structure, species diversity recovery during secondary succession in 179 plots. Our study provides first field-based quantification AGB following abandonment by two types (heavy machinery suction pumping) Madre de Dios (Peru). found that successional forests areas subjected to pumping were more resilient than those heavy machinery. After 20 years, mean mining had reached 56% reference AGB, while it was only 18%. Mining type, stand age, distance from edge significant effect on AGB. The influence varies according type because effects mediated edge. results clearly showed dynamics across after goldmining, contrasting responses between types. disentangles importance key factors improves understanding resilience accumulation these highly degraded ecosystems.

Abstract The shortage of decades‐long continuous measurements ecosystem processes limits our understanding how changing climate impacts forest ecosystems. We used eddy‐covariance and hydrometeorological data over 2002–2022 from a young Douglas‐fir stand on Vancouver Island, Canada to assess the long‐term trend interannual variability in evapotranspiration ( ET ) transpiration T ). Collectively, annual displayed decreasing 21 years with rate 1% yr −1 , which is attributed stomatal downregulation induced by rising atmospheric CO 2 concentration. Similarly, also showed since evaporation stayed relatively constant. Variability detrended was mostly controlled average soil water storage during growing season (May–October). Though duration intensity drought did not increase, drought‐induced decreases an increasing trend. This pattern may reflect changes structure, related decline deciduous understory cover development. These results suggest that water‐saving effect regulation water‐related factors determined respectively. imply increase limitation availability forests, associated structural compositional growth.

Abstract Light availability profoundly influences plant communities, especially below dense tree canopies in forests. Canopy disturbances, altering forest floor light conditions, together with other environmental changes such as climate change, nitrogen deposition and legacy effects from previous land‐use will simultaneously impact understorey communities. Yet, knowledge on the individual of these drivers their potential interactions remains scarce. Here we performed a mesocosm experiment to assess influence warming, illumination (simulating canopy opening), soil history (comparing ancient post‐agricultural soil) community composition trajectories over 7‐year period. Strikingly, communities primarily evolved response deeply shaded ambient experimental treatments exerting only secondary influences. The overruling trajectory steered all mesocosms towards slow‐colonizing specialist dominated by spring geophytes lower nutrient‐demand. treatment and, lesser extent, warming agricultural slowed down this trend advancing fast‐growing resource‐acquisitive generalist species. Warm temperatures induced thermophilization treatments, including control plots, higher dominance warm‐adapted Nitrogen addition accelerated process increased light‐demand signature. Land‐use were limited our study. Our findings underscore essential role preserving specialists highlight importance maintaining cover attenuate global change impacts. It is crucial integrate management adaptation particularly face increasing demands for wood products intensified natural disturbances.
