Summary: Allometric scaling studies are important for understanding the morphology, function, and behavior of trees in ecology. This study investigated the allometric relationships between branch lengths in 3D vector mode using a detailed quantitative structure model and 3D point cloud data. The results showed that the scalar and vector relationships between branch lengths and the lengths of cumulative child branches were similar among trees. The relationships between the horizontal and vertical components of branch lengths and the cumulative lengths of child branches differed significantly.

Summary: Quantifying whole branch architecture is crucial for understanding tree function, but measuring small diameter branches is challenging. Methods using terrestrial laser scanning are applied to analyze tree architecture, but accurately reconstructing small diameter branches remains difficult. It is suggested that accurate reconstruction can only be achieved through harvest and measurement in controlled conditions.

Summary: Illegal logging is a major cause of tropical forest loss. Satellite-based alert systems can accurately estimate tree cover loss in logging concessions using 10 m scale satellite data, but reliability is lower in areas with few disturbances. There is a trade-off between aggregation level and accuracy in estimating logging volumes, which presents a challenge for remote verification of logging activities.

Summary: Amazonian forests play a vital role as reservoirs of biomass and biodiversity, contributing to climate change mitigation. This study examines the impact of disturbances on forest biomass and biodiversity in the Peruvian Amazon, using tree-level data and remotely sensed monitoring. The results show that disturbance intensity negatively affects tree species richness and biomass recovery. Surprisingly, time since disturbance has a small negative effect on species richness. Approximately 15% of Peruvian Amazonian forests have experienced disturbance since 1984, with an increase in biomass of 4.7 Mg ha(-1) year(-1) during the first 20 years.

Summary: This study assessed the net Delta AGB derived from four global multi-date AGB maps over the past decade. The comparison between LiDAR data and maps showed reasonable agreement, while the comparisons using NFI only had some agreements at smaller aggregation levels. Disagreement between maps is still large in key forest regions. The results suggest that the AGB assessed from current maps can be biased and any use of the estimates should consider this.

Summary: Accurate information about tropical forest disturbances is crucial for forest management and law enforcement. Monitoring forest disturbances using cloud-penetrating SAR imagery has shown effective results. However, current methods based on backscatter values may cause omission errors. This research proposes a method to quantify the heterogeneity of neighboring pixel values using textural features, in order to overcome omission errors caused by post-disturbance tree remnants or debris. The combination of SAR-based textural features and backscatter improves the consistency and timeliness of forest disturbance monitoring.

Summary: This study analyzed the effects of site and climate on the self-thinning line in Scots pine forests in Europe. The results showed that species tolerance, temperature, and precipitation influenced the slope of the self-thinning line. In terms of the intercept, latitude and radiation had compensating effects. Time did not show significant trends in the self-thinning line. The study highlights the need to adapt management strategies and models based on self-thinning to different latitudes. Climate change has not yet significantly impacted the self-thinning trajectory, but a continuous rise in temperature and high precipitation may accelerate the self-thinning process and result in increased biomass accumulation.

Summary: Secondary forests play a crucial role in ecosystem dynamics and biodiversity recovery. This study investigated the mechanisms underlying secondary succession in a restored secondary forest and found that deciduous tree species transition from diversity accumulators to repellents as they progress through different life history stages, while evergreen tree species can act as accumulators or remain neutral. The study also revealed the effects of density dependence on the mortality and regeneration of different tree species, and highlighted the importance of early-arriving tree species in facilitating the establishment and diversity of late-arriving counterparts.

Summary: Regeneration failures in the closed-crown boreal forest, resulting in the creation of open lichen woodlands, can be restored through clear-cutting, scarification, and natural seeding. Clear-cutting combined with scarification promotes seedling establishment, and scarification creates suitable microsites for germination. Seedling growth in lichen woodlands is higher when logging and scarification are combined, but lower compared to feather moss stands. Afforestation through natural seeding following scarification could be a cost-effective option for restoring lichen woodlands.
