Aim Variation in species composition among locations (β‐diversity) is of fundamental interest in ecology, yet its dependence on spatial extent and grain has rarely been assessed empirically. This study provides a systematic empirical test of the spatial scaling of β‐diversity and highlights the importance of study design for detecting the role of environmental filtering in shaping regional β‐diversity. Location Northeastern Ch...

Aim Nitrogen deposition is a widespread global change driver that significantly affects terrestrial ecosystems. However, evidence on the specific mechanisms of productivity response to nitrogen deposition in temperate forests across ecological and climatic gradients is scarce. This study evaluates the effects of nitrogen deposition, multiple attributes of biodiversity and climate on productivity in a large temperate forest reg...

Aim The underlying drivers of latitudinal gradients in multifaceted β‐diversity remain debated. The primary focus on abiotic drivers of β‐diversity has left dispersal processes insufficiently explored. This study presents a multiscale analysis of how dispersal, Quaternary climate and contemporary environmental conditions influence multifaceted β‐diversity and its decomposition components in a large temperate forest. Location N...

Climate variability poses a significant threat to ecosystem function and stability. Previous studies suggest that multiple facets of biodiversity enhance the temporal stability of forest ecosystem functioning through compensatory effects. However, as climate change intensifies, two key questions remain unresolved: (1) the mechanisms by which different biodiversity facets sustain the temporal stability of carbon sequestration a...

Tree growth and lifespan are key determinants of forest dynamics, and ultimately control carbon stocks. Warming and increasing CO 2 have been observed to increase growth but such increases may not result in large net biomass gains due to trade‐offs between growth and lifespan. A deeper understanding of the nature of the trade‐off and its potential spatial variation is crucial to improve predictions of the future carbon sink. T...
