Summary: The study examined the hydrological effects of natural regeneration of Tropical Montane Cloud Forests (TMCF), finding that an increase in TMCF cover can contribute to increases in water yield. However, to ensure significant effects, regeneration and/or successional development of TMCF has to reach at least 20% of a catchment area.

Summary: Tropical Montane Cloud Forests (TMCFs) provide important ecosystem services but are threatened by deforestation and climate change. Challenges in assessing the quantity of TMCFs include uncertainty in geographical location and limited availability of meteorological data. Changes in tree cover and greenness varied across continents in TMCFs, and climate change signals differed geographically.

Summary: In the Amazon basin, birds in floodplain forests adapt to seasonal flooding by migrating vertically to higher forest strata without significant changes in vegetation density relative to water level. The reduction in available space during floods increases prey density for insectivorous birds, allowing them to maintain territoriality without major habitat shifts throughout the year.

Summary: As the usage of three-dimensional (3D) laser scanner becomes prevalent for forest inventory, the analysis and processing of point cloud data captured with a 3D laser scanner have gained significant research attention. Extracting individual trees from point cloud data is crucial for further investigation at the tree-level analysis, such as tree counting and trunk analysis, leading to multiple advancements in this area. However, accurately and automatically obtaining the tree crown silhouette from the point cloud data is challenging due to the frequent overlap between adjacent tree crowns. To address this issue, a soft segmentation method utilizing K-Nearest Neighbor (KNN) and contour shape constraints has been proposed, resulting in improved visual effect and precision of point cloud segmentation. In conclusion, the proposed method demonstrates a successful approach for tree crown segmentation and silhouette reconstruction from terrestrial laser scanning point cloud data of forests.

Summary: Tropical montane ecosystems have high biodiversity and the variability of mountain climate is important for sustaining this diversity. In this study, we tested this hypothesis for soil bacteria and fungi along an elevational gradient in Hainan Island, China. We found that bacterial and fungal diversity decreased with increasing elevation, and their dissimilarities increased with greater separation in elevation. Soil moisture and pH were the major drivers of fungal and bacterial diversity respectively, while soil temperature was the main driver of dissimilarities in bacterial and fungal communities. Our findings indicate that local-climate variability plays a crucial role in structuring soil microbial communities along tropical montane gradients, and they may shift in response to future climate scenarios.

Summary: Fog plays a crucial role in maintaining montane cloud forest ecosystems. Future climate changes may impact the hydroclimatology of cloud forests. Increased rainfall intensity decreases the accumulation of canopy water, while higher water vapor concentrations lead to more nighttime condensation on leaves. Elevated CO2 concentrations have minimal effects on canopy water, but enhance photosynthesis and reduce transpiration. Evapotranspiration decreases in cloud forest regions, contrasting with the expected intensification in the global water cycle under global warming.

Summary: The study found that forest edges have a significant impact on the avian species composition, especially for endemic species, along the gradient from cloud forest to dry forest. This suggests that habitat modification at forest edges may have a differential effect on different types of bird species.

Summary: Despite their small size and limited distribution, tropical montane forests (TMFs) are important for biodiversity and ecosystem services, but are vulnerable to climate change. To improve conservation efforts, it is crucial to use scientific evidence and identify research gaps. This study assessed the impacts of climate change on TMFs, finding a lack of long-term data and a focus on predictive modeling rather than experimental studies.

Summary: This study investigated how fog modulates the energy and hydrological cycles of montane cloud forests, highlighting the unique hydroclimatological cycle in this region and the inseparable relationship between canopy and near-surface meteorology during the diurnal cycle. The partitioning of latent heat flux and its impact on local hydroclimate remain unclear, warranting further research to better understand the complex interactions in montane cloud forests.

Summary: This study focuses on the impact of climate change on tropical montane forest ecosystems in the Peruvian Andes, projecting that by 2070, 58% of all montane forests will be in areas with high potential impact, particularly between 800 and 1200 meters above sea level. Additionally, around 64% of montane forests in protected areas are expected to be exposed to high potential impact.

Summary: Recent studies have identified fog-driven epiphyte-rich tropical cloud forests in the lowlands of French Guiana. A high-resolution product based on satellite images has shown widespread occurrence of fog/low stratus clouds (FLS) in the entire tropical lowland rain forest of South America, providing suitable environmental conditions for the Tropical Lowland Cloud Forest (TLCF). This knowledge on the spatial distribution of potential TLCF is crucial for conservation efforts.

Summary: This study investigated the importance of ancient forests for the conservation of threatened species in mountain and subalpine protected areas in France. The results showed that historical forest had a positive effect on certain taxonomic groups, such as Spermatophyta, Bryophyta, Coleoptera, and edge forest Pteridophyta, while negatively affecting edgeforest lepidopterans. These findings highlight the importance of protecting ancient forests for preserving threatened forest species.

Summary: The study evaluated the AMF community composition and soil infectivity in urban sites with different disturbance levels and management histories in Cordoba, Argentina. The results showed that AMF communities were dominated by generalist species that are resilient to harsh environmental conditions. Urban forests had higher richness, diversity, and soil infectivity compared to parklands, with plant diversity, tree cover dominance, and soil compaction playing key roles in shaping AMF communities.

Summary: The genus Nacobbus, a type of nematode found in the Americas, can cause significant economic losses on major food crops and is subject to strict quarantine legislation. However, the management of Nacobbus spp. remains unsatisfactory due to lack of information on its life cycle, detection methods, and resistant plant genotypes. This review focuses on environmentally benign treatments for Nacobbus spp., including biological control strategies and other eco-compatible approaches. Potential sources of resistance for genetic improvement are also discussed. These sustainable strategies not only help combat the pathogen, but also improve crop health and growth.
