Summary: Forest fragmentation can increase the deposition of atmospheric ammonia (NH3) from agricultural areas, affecting the spatial variability of nitrogen (Nr) deposition within the forest. This study found that NH3 deposition dominated the annual total nitrogen deposition to tree canopies in a Japanese fragmented forest. Additionally, agricultural activities near the forest enhanced the retention of NH4+ in the tree canopy, leading to higher growth rates of trees and understory vegetation at the forest edge.

Summary: With climate warming intensifying, the risk of more frequent and hotter droughts to forest ecosystems globally, including temperate biomes, is significant. To accurately predict forests' response to drought, it is crucial to provide comprehensive information on tree growth resilience, its spatiotemporal changes, and the factors driving it. However, such information is often lacking for broadleaf species in temperate regions. In this study, the researchers analyzed ring-width series from 1981 trees across 40 sites in northeastern China, covering four dominant broad-leaf tree species. They found that factors such as minimum temperatures in most seasons, warm conditions, and drought stress in early summer were the main limitations to tree growth. Different tree species displayed varying levels of resistance and recovery to drought, with Quercus mongolica having the weakest growth resistance but the fastest growth recovery. The study also revealed spatial patterns in tree resilience driven by differences in site conditions and local climates. It highlighted the importance of considering biogeographical factors when studying forest resilience to drought.

Summary: Climate change is directly altering the bioclimatic conditions during the growing period of trees, as well as indirectly affecting the timing and length of the season through shifts in leaf phenology. Research shows that climate change has led to advanced leaf unfolding and delayed leaf colouring, impacting the growing period and precipitation levels for different tree species in Central Europe. The findings suggest an increased drought stress, particularly at lower elevations, with future forest productivity depending significantly on elevation and species composition.

Summary: The study found that climate change has species-specific effects on different active earthworm species, but has limited interactions with land-use types. Intensive grassland management decreased the abundance of active earthworms, while sheep grazing favored earthworm populations. Overall, the response of earthworm communities to climate change and land use types is complex and context-dependent.

Summary: The study found that in the presence of pathogens, the increase in carbon allocation to sink leaves and the increase in nitrogen allocation to lateral roots did not occur during growth flushes, but these resource allocation shifts were mostly restored with additional interaction with the EMF. The presence of the EMF led to increased resource allocation to principal roots during root flushes, even when other interactors were present. These interactors affected the alternating, rhythmic growth and resource allocation shifts between shoots and roots, with the EMF supporting plants in maintaining the ERG.

Summary: Climate change and land-use intensification pose increasing threats to biodiversity. In a field-scale grassland experiment, we tested the combined effects of climate change and land-use intensification on arthropod biodiversity. We found that climate change reduced arthropod abundance, while land-use intensification reduced overall community abundance and altered species composition. These changes will have profound consequences for ecosystem functioning under future environmental conditions.

Summary: This study investigates the decomposition of wheat straw under future climate conditions and reveals that future climate will accelerate the decay rate of straw only in the early phases of decomposition. It also shows that the projected climate change will increase the abundance of saprotrophic fungi in decomposing wheat straw, and that the impact of future climate on microbial community assembly and interaction networks will depend on the decomposition phase. The study concludes that the impact of future climate on straw decay and microbial traits is limited to the early phases of decomposition.

Summary: This study examined the impact of climate change and land use patterns on the biomass patterns of Collembola, focusing on different life forms. The results showed that the response of Collembola biomass to these changes varied among different life forms. Specifically, surface-dwelling Collembola experienced a significant decrease in biomass, while soil-living Collembola were less affected. The reduction in Collembola biomass was mainly due to climate change-induced body size shrinkage and intensive land use-induced density reduction.
