Summary: The Changbai Mountain area in China is a significant region for mineral water storage and development. The composition of hydrochemicals is crucial for determining mineral water quality. Through analyzing hydrochemical data from 74 mineral water samples collected between 2018 and 2020, this study investigated the characteristics and formation mechanism of hydrochemical components in mineral water. The results indicated that single-type mineral springs are formed through rock weathering control, while compound mineral springs result from the combination of CO2-rich, weakly acidic, confined hot groundwater with high salinity mixing with shallow groundwater along fractures. The volcanic geological process significantly influences the hydrochemical components of mineral springs on the North slope of Changbai Mountain, while human activities greatly impact the mineral springs on Longgang Mountain. The findings of this study contribute to understanding the distribution, hydrochemical characteristics, and formation mechanism of mineral springs in the Changbai Mountain area, providing a theoretical basis for their protection and development.

Summary: This study investigated the variation, diversity, and community assembly of root chemical traits in the fine roots of 204 plant species along an elevational transect in Changbai Mountain, China. The concentrations of macronutrients decreased with elevation, while trace metals increased. The root chemical traits at the community level showed a similar pattern to that at the species level, mainly influenced by climate and soil factors. The interactions of climate and soil were the main drivers of root chemical assembly for woody layers, while soil factors played a significant role for herb layers. Root chemical diversities were mainly regulated by species diversity, the interactions of climate and soil, and soil factors in the tree, shrub, and herb layers, respectively. A better understanding of plant root chemical diversity and community chemical assembly is important for understanding ecosystem functioning.

Summary: Antu County in the Changbai Mountains is an important source of mineral water. However, there is insufficient research on the source of groundwater characteristic components, which affects the protection of water resources. This study reveals the formation mechanism of characteristic components in groundwater through analysis of hydrochemical and isotopic data. It identifies metasilicic acid as a common component and confirms that the groundwater primarily receives recharge from low-mineralized precipitation, allowing for sufficient time for water-rock interaction.

Summary: Debate exists regarding which tree species can sustain forest ecosystem services in a drier and warmer future. The use of non-native timber species, like Douglas fir, is suggested as a solution to mitigate climate change impacts in Europe. However, more research is needed to define the biogeographical, climatic, and ecological limits for widely planted timber species. This study found that the growth of Douglas fir is constrained by warm and dry conditions, particularly in dry areas.

Summary: During the past years, water shortage has hindered the growth and productivity of various oak species in seasonally dry regions like the Mediterranean Basin. Thinning has the potential to improve oak growth in these drought-prone areas by reducing tree competition for soil water. However, there is still a lack of long-term assessments on the lasting effects of thinning treatments and their contribution to oak growth recovery after drought.

Summary: The relationship between tree growth and gross primary production with drought is influenced by stand characteristics and competition, with stand density playing a significant role in long-term growth responses. Canopy densification drives the pattern and trends in summer NDVI, indicating the importance of stand canopy coverage. Short-term growth and NDVI responses to severe droughts are independent of stand characteristics.

Summary: The authors found that early spring phenology slows drought recovery, while delayed spring phenology prolongs it. More than half of ecosystems in the mid- and high-latitudinal Northern Hemisphere fail to recover from extreme droughts within a single growing season. The phenology effects on drought recovery are comparable to or larger than other well-known postdrought climatic factors, suggesting the need to incorporate these interactions into Earth system models.

Summary: Intensive livestock management can cause nitrogen pollution in water bodies, but the impact of manure application on agroforestry systems is not well understood. This study assessed how pig manure affects tree growth and the nitrogen cycle in two commonly planted tree species. The results showed that fertilized trees had higher soil nutrient concentrations but lower soil microbial biomass. Pine trees showed similar growth between fertilized and non-fertilized trees, while almond trees showed lower growth when fertilized. Leaf nitrogen concentrations decreased, but wood nitrogen isotopes increased in trees subjected to pig manure application. This suggests that pig manure alters nitrogen cycling in both soil and trees.

Summary: Recent drought-induced dieback affects forest dynamics, which are also influenced by past management. In western Pyrenean silver fir stands, dieback coincides with past management legacies, but their impacts on forest growth, structure, and composition are unknown. This study examines how dieback interacts with past human use and modulates the dynamics of silver fir forests. Results show that silver fir growth declines in response to drought, and declining sites have lower density and higher dependence on water availability. Tree death increases the cover of dominant understory plants. Past management activities leave a mark on silver fir growth and affect tree density. Further monitoring is needed to fully understand the influences of past management legacies and current climate change on forest dynamics.

Summary: Assessing tree growth patterns and deviations from climate baselines is important for determining forest vulnerability to drought. In the case of silver fir populations in the Spanish Pyrenees, ongoing dieback processes have been observed since the 1980s. Our study found that the most intense dieback occurred in low-elevation sites in the western Pyrenees, with trees displaying low growth rates and high variability in growth. In contrast, the eastern and central Pyrenees showed mild growth limitation by low soil moisture and positive growth recovery in recent years.

Summary: Ongoing climatic change poses a threat to drought-sensitive tree species like silver fir. This study used ddRADseq to examine the genetic characteristics of declining and non-declining silver fir trees in the Spanish Pyrenees. While no genetic differences were found between the two groups, there were strong associations between the genome and environmental factors, suggesting the influence of climate, soil properties, and microbial diversity on local adaptation. Incorporating genetic data into silver fir forest dieback studies can provide valuable insights into local adaptation.
