Abstract Aim Biodiversity across different scales provides multidimensional insurance for ecosystem functioning. Although the effects of biodiversity on multifunctionality are well recorded in local communities, they remain poorly understood (from to larger spatial scales). This study evaluates how multiple attributes maintain from regional scales, diverse environmental gradients. Location North‐eastern China. Time Period 2017. Major Taxa Studied Woody plants. Methods We define using both averaged and modified multiple‐threshold approaches. Multiple dimensions varying were measured within framework Hill–Chao numbers. Using variance decomposition, linear mixed models structural equation modelling, we explored tree diversity at affect multifunctionality, these relationships modulated by drivers. Results found that α‐ β‐diversity critical community while between species, functional phylogenetic decoupled thresholds Phylogenetic species α‐diversity are, respectively, more important promoting high‐ moderate‐threshold (e.g. EMF T90 T50 ) communities. Environmental drivers typically have stronger than multifunctionality. Soil climatic conditions had either direct or indirect ones mediated α‐diversity. heterogeneity is high‐threshold exerting directly indirectly through β‐diversity. Latitude not only influences but also modulates it Main Conclusions underscores positive dimensions. Based our findings, conclude any design a forested landscape aimed maximizing should consider maintaining high as forest scales.

Conventional farming practices can lead to soil degradation and a decline in productivity. Regenerative agriculture (RA) is purported by advocates as solution these issues that focuses on health carbon sequestration. The fundamental principles of RA are keep the covered, minimise disturbance, preserve living roots year round, increase species diversity, integrate livestock, limit or eliminate use synthetic compounds (such herbicides fertilisers). overall objectives rejuvenate land provide environmental, economic, social benefits wider community. Despite RA, vast majority growers reluctant adopt due lack empirical evidence claimed profitability. We examined reported mechanisms associated with against available scientific data. literature suggests agricultural such minimum tillage, residue retention, cover cropping improve carbon, crop yield, certain climatic zones types. Excessive chemicals biodiversity loss ecosystem degradation. Combining livestock agroforestry same landscape several co-benefits. However, vary among different agroecosystems may not necessarily be applicable across multiple agroecological regions. Our recommendation implement rigorous long-term system trials compare conventional order build knowledge regional scales. This will policy-makers an base from which make informed decisions about adopting realise their economic achieve resilience climate change.

Abstract Biodiversity across multiple trophic levels is required to maintain ecosystem functions. Yet it remains unclear how multitrophic diversity and species interactions regulate multifunctionality. Here, combining data from 9 different groups (including trees, shrubs, herbs, leaf mites, small mammals, bacteria, pathogenic fungi, saprophytic symbiotic fungi) 13 functions related supporting, provisioning, regulating services, we used a perspective evaluate the effects of elevation, diversity, network complexity on scale‐dependent subalpine forest Our results demonstrated that elevation soil pH significantly modified composition richness influenced simultaneously. We present evidence had stronger multifunctionality than at any single level. Moreover, biotic associations, indicating networks, were positively associated with The relative increased scale larger community compared accounting for neighboring interactions. highlight paramount importance scale‐ context‐dependent better understanding mountain in changing world.

Abstract Diversity–biomass relationships (DBRs) often vary with spatial scale in terrestrial ecosystems, but the mechanisms driving these scale‐dependent patterns remain unclear, especially for highly heterogeneous forest ecosystems. This study explores how mutualistic associations between trees and different mycorrhizal fungi, i.e., arbuscular (AM) vs. ectomycorrhizal (EM) association, modulate DBRs. We hypothesized that soil‐heterogeneous forests a mixture of AM EM tree species, (i) species would respond contrasting ways (i.e., positively negatively, respectively) to increasing soil fertility, (ii) dominance contribute higher diversity greater standing biomass, as result (iii) exert an overall negative effect on DBRs across scales. To empirically test hypotheses, we collected detailed distribution information (e.g., nitrogen, phosphorus, organic matter, pH) from seven temperate subtropical AM–EM mixed megaplots (16–50 ha). Using codispersion null model structural equation modeling, identified among or dominance, diversity, biomass and, thus, 0.01‐ 1‐ha found first evidence supporting three aforementioned hypotheses forests: In most forests, communities changed EM‐dominated AM‐dominated; had positive even after controlling fertility number trees. Together, changes along gradients weakened DBR observed at 0.04‐ha scales nearly all drove 0.25‐ four out forests. Hence, this highlights soil‐related mechanism could partly explain why, many natural biodiversity–ecosystem functioning (BEF) shift scale.

Intensive agriculture with high reliance on pesticides and fertilizers constitutes a major strategy for 'feeding the world'. However, such conventional intensification is linked to diminishing returns can result in 'intensification traps'-production declines triggered by negative feedback of biodiversity loss at input levels. Here we developed novel framework that accounts crop yields evaluate risk magnitude traps. Simulations grounded systematic literature reviews showed traps emerge most landscape types, but lesser extent cereal production systems. Furthermore, small reductions maximal (5-10%) could be frequently transmitted into substantial gains, resulting small-loss large-gain trade-offs prevailing across types. sensitivity analyses revealed strong context dependence trap emergence, inducing uncertainty identification optimal management field scale. Hence, recommend development case-specific safety margins preventing double losses food security associated
