Functional diversity is critical for ecosystem dynamics, stability and productivity. However, dynamic global vegetation models (DGVMs) which are increasingly used to simulate functions under change, condense functional plant types (PFTs) with constant parameters. Here, we develop an individual- trait-based version of the DGVM LPJmL (Lund-Potsdam-Jena managed Land) called LPJmL- flexible individual traits (LPJmL-FIT) traits) apply generate trait maps Amazon basin. LPJmL-FIT incorporates empirical ranges five tropical trees extracted from TRY database, namely specific leaf area (SLA), longevity (LL), nitrogen content (Narea ), maximum carboxylation rate Rubisco per (vcmaxarea), wood density (WD). To scale growth performance trees, linked by trade-offs based on economics spectrum, whereas tree mortality. No preselection strategies taking place, because individuals unique combinations uniformly distributed at establishment. We validate modeled distributions data biomass a remote sensing product along climatic gradient. Including variability successfully predicts natural achieves more realistic representation local regional scale. As sites high variability, fringes promote divergence coexistence multiple strategies, while lower found in species-rich center region relatively low variability. enables test hypotheses effects biodiversity functioning current challenges management scales, that is, deforestation climate change effects.

Summary The provisioning of ecosystem services to society is increasingly under pressure from global change. Changing disturbance regimes are particular concern in this context due their high potential impact on structure, function and composition. Resilience‐based stewardship advocated address these changes management, but its operational implementation has remained challenging. We review observed expected impacts provisioning, regulating, cultural supporting services, concentrating temperate boreal forests. Subsequently, we focus resilience as a powerful concept quantify impacts, present an approach towards application using established methods ecology. suggest the range variability – characterizing bounding long‐term behaviour ecosystems locate delineate basins attraction system. System recovery relation can be used measure ecosystems, allowing inferences both engineering (recovery rate) monitoring for regime shifts (directionality trajectory). It important consider dynamic nature properties analysis management decision‐making, processes mechanisms will subject future. Furthermore, because at interface between natural human systems, social dimension (social adaptive capacity variability) requires consideration responding changing Synthesis applications .

Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management schemes that may mitigate potential ecological harm by increasing species richness boosting related to agroecosystems. What remains unclear extent affect components other than richness, whether impacts differ across spatial scales landscape contexts. Using metadataset, we quantified effects organic on abundance, local diversity (communities within fields), regional fields) arthropod pollinators, predators, herbivores, detritivores. Both higher in-field enhanced particularly for rare taxa. This resulted increased but decreased evenness. While these responses were stronger at relative scales, abundance both farms embedded complex simple landscapes. Overall, exerted strongest pollinators suggesting facilitate service providers without augmenting herbivore (pest) populations. Our results suggest promote diverse metacommunities provide temporal stability provisioning. Conserving communities systems therefore requires sustainable practices operate fields

Summary Trait‐based approaches are increasingly being used to test mechanisms underlying species assemblages and biotic interactions across a wide range of organisms including terrestrial arthropods investigate consequences for ecosystem processes. Such an approach relies on the standardized measurement functional traits that can be applied taxa regions. Currently, however, unified methods trait measurements lacking related macroinvertebrates (terrestrial invertebrates hereafter). Here, we present comprehensive review detailed protocol set 29 known sensitive global stressors affect processes services. We give recommendations how measure these under conditions various invertebrate taxonomic groups. provide considerations apply almost all described, such as selection individuals needed measurements, importance intraspecific variability, many populations or communities sample over which spatial scales. The outlined here means improve reliability predictive power explain community assembly, diversity patterns services within trophic levels, allowing comparison studies running meta‐analyses regions ecosystems.

Assessing functional diversity from space can help predict productivity and stability of forest ecosystems at global scale using biodiversity-ecosystem functioning relationships. We present a new spatially continuous method to map regional patterns tree combined laser scanning imaging spectroscopy. The does not require prior taxonomic information integrates variation in plant traits between within species. compare our with leaf-level field measurements species-level plot inventory data find reasonable agreement. Morphological physiological show consistent change topography soil, low richness mountain ridge under specific environmental conditions. Overall, follows logarithmic increase area, whereas divergence evenness are invariant. By mapping scales individual trees whole communities we demonstrate the potential assessing space, providing pathway only limited by technological advances methodology.
