Summary: Detailed information on spatial patterns of tree species diversity (TSD) is crucial for biodiversity assessment and forest management. This study developed a new workflow for large-scale TSD mapping using Sentinel-1 and Sentinel-2 imagery and topographic data, and found that the combination of these data sources yielded the highest accuracy in TSD predictions.

Summary: The study found that tree mortality rates significantly decreased with elevation, precipitation seasonality, plot-mean wood density, and plot-mean square diameter, but significantly increased with total annual precipitation, mean annual temperature, and productivity. Individual-based mortality increased in old-growth forests between 1991-92 and 2016-17. The main drivers of increasing tree mortality over time are still unknown, but may be related to increasing precipitation and temperature in the region.

Summary: Climate variations affect the adaptive capacity of trees in tropical montane cloud forests, with leaf vein morphology being related to specific climatic oscillations. Different Magnolia species exhibit variations in leaf vein traits along altitudinal gradients, adapting differently to humidity and hydric deficit. This study provides insights into identifying the most vulnerable Magnolia species to climate change effects, highlighting the importance of conservation efforts in Mexican tropical montane cloud forests.

Summary: In situ sap-flow measurements from Eastern Himalayan secondary tropical montane forests suggest that shallow-rooted pioneers are more vulnerable to drier and warmer winters than deep-rooted late-successional species. The interactive role of life-history traits and environmental factors on plant water relations is crucial for understanding the responses of species to climate change, but it remains poorly understood in secondary tropical montane forests.

Summary: Andean tropical montane forests are biodiversity hotspots that play important roles in providing hydrological services and carbon storage. Abandonment of agroforestry systems may lead to secondary succession, and the conservation of secondary forests is crucial for mitigating and adapting to climate change and supporting biodiversity.

Summary: Tropical secondary forests play a crucial role in carbon sequestration and biodiversity conservation, but their recovery rates vary widely and are influenced by various environmental factors. Aboveground biomass recovers quickly in the early stages of succession, while tree species richness increases at a slower pace. Recovery rates differ significantly among forests.

Summary: Having knowledge about the distribution of tree species at a national scale is beneficial for forest management practices and decision making regarding the selection of suitable tree species for specific locations. The accurate identification of tree species in relation to their locations enables assessments of their resilience or vulnerability to various factors. This study used data from the national forest inventory in Germany to develop a machine-learning approach that classified a dense time series of satellite imagery, resulting in a map showing the dominant tree species in German forests. The accuracy of the model was validated through tests and comparisons with independent forest stand inventories and statistics from the national forest inventory.

Summary: The study reveals that the aboveground carbon stock of a montane African forest network is comparable to that of a lowland African forest network, and is two-thirds higher than default values for these montane forests. The research provides country-specific montane forest AGC stock estimates modeled from the plot network, aiming to guide forest conservation and reforestation interventions. The findings emphasize the need to conserve these biodiverse and carbon-rich ecosystems.

Summary: Studies have shown significant impacts of climate warming on the spatial and temporal changes in mountain tree diversity over the past four decades, with varying sensitivity to warming in different regions. Priority protection should be given to Minshan and Xiaoxiangling in the Giant Panda National Park due to their higher sensitivity to climate warming. The Park should adopt a tailored approach for diversity conservation considering spatial heterogeneity in plant community dynamics.

Summary: The study found that amphibian species richness increases towards the equator in the Neotropics, with distinct patterns in different taxa and their relationship to climate variables. Climate variables explained less than half of the variations in total species richness, indicating that factors such as historical biogeography and orographic heterogeneity may also play crucial roles.

Summary: Understanding the relationship between forest tree composition structure and environmental and disturbance gradients is crucial for conservation and management decisions. This study quantified this relationship in a tropical sub-montane forest, finding that environmental factors explained a significant amount of variation in tree species and community composition, emphasizing the need for site-specific assessments. Additionally, human disturbance had a minor but still noticeable impact on composition, highlighting the importance of minimizing human activities to preserve forest species patterns.

Summary: This study contributes to the knowledge of the diversity of Russula species in subsection Roseinae based on specimens collected in tropical montane rainforests in western Panama. Four new species were described and illustrated, showing closer relation to North American or Asian species. Two of the species were associated with Oreomunnea mexicana, while the other two were associated with Quercus species, all only known from mountains in western Panama.

Summary: This study presents auxiliary support techniques for tree selection strategies in secondary forests based on spatial structure indices and competition indices. It emphasizes the importance of tree competition in forest management. Using GIS and C# programming languages, selective thinning was simulated based on target tree-based management principles. The results support the use of auxiliary technology for scientifically selecting trees for thinning and highlight the significance of competition indices in the selection process.
