Summary: This study found that in the dioecious tropical forest tree species Mollinedia schottiana, there is no significant difference in sex-related costs between females and males, with females not showing higher investment loss or growth disadvantage. The male-biased sex ratio is likely a result of the plant's floral biology strategy for pollination by thrips.

Summary: This study focused on pollen and seed flow within a regenerant population of Astronium fraxinifolium, revealing that the majority of pollen and seeds originated from trees outside the sampled populations and were dispersed through isolation by distance. Genetic diversity was similar between adult trees from different locations and individuals from the regenerant population, but significant levels of inbreeding were detected within the regenerant population.

Summary: This study investigated the survival rates and the development of adventitious roots in four tree species under different shading and water levels. It found that some tree species were able to survive and adapt to inundation through the development of adventitious roots, while others required lower water levels. Additionally, some tree species thrived under moderate shading levels, while others required full sunlight.

Summary: The study compiled and presented a database of timber species in the Amazon region, based on official information from nine South American countries and scientific references. They verified taxonomic names from each source and considered tree species with a diameter at breast height (DBH) ≥10 cm. Population estimates were obtained from tree inventory plots and the Amazon Tree Diversity Network. The database includes information on conservation, trade status, and population of each species.

Summary: The impact of increasing tropical cyclone (TC) activity on temperate forests in the eastern United States was investigated through the use of structural equation models. High TC activity was found to lead to a decrease in the size of trees, an increase in tree density and basal area, and a decline in tree species richness. TC activity was identified as the strongest predictor of forest structure and species richness in dry forests, while its impact on wet forests was weaker. These results highlight the sensitivity of temperate forests to future increases in TC activity and the potential decline in tree species richness.

Summary: The encroachment of forests into savannas is a common phenomenon, with the rate depending on factors such as soil conditions, species composition, and changes in stand structure. Savanna specialist trees are being replaced by generalist species, causing faster rates of stand development. Generalists are able to persist in forests and have faster growth rates, enabling them to outcompete and suppress savanna specialists.

Summary: Understanding how evolutionary history and trait trade-off axes shape the drought tolerance of trees is crucial for predicting forest dynamics under climate change. This study compiled traits related to drought tolerance in tropical woody species, finding that xylem resistance to embolism and leaf turgor loss point determine the risk of hydraulic failure, with leaf phosphorus concentration also playing a role. The results suggest that drought tolerance is under strong selective pressure in tropical forests and is coordinated with ecological strategies governing forest demography.

In addition, LightGBM and CNN1D showed high predictive abilities with smaller subsets of SNPs. The research suggests that genomic selection with GWAS-based SNP selection can be effective in breeding non-cultivated tree species to improve initial growth.

The findings reveal that subpopulations are not reproductively isolated, with significant pollen flow occurring both within and between subpopulations. The study also highlights the self-compatibility of C. estrellensis, but with non-random mating patterns due to biparental inbreeding and correlated paternity. Spatial genetic structure is observed, suggesting the importance of certain distances for successful conservation efforts.

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.

Through soil charcoal analysis in the Lorraine Plateau in France, the presence of Fagus and Quercus in mature Quercus stands was confirmed. Radiocarbon dating results indicated that historical forest management caused the replacement of Fagus by Quercus, starting from the Bronze Age.

The results show that combining UAV and field data can improve the prediction of tree diameter increment. Diameter at breast height and crown area are complementary predictors, and crown-based competition indices significantly enhance prediction models.

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.
