Summary: The study reveals clear seasonal variability of soil phosphorus pools in tropical forests, where P released during litter decomposition is positively correlated with changes in organic P fractions, while the net change in organic P fractions is negatively correlated with phosphatase activities in the top 5 cm of soil. This emphasizes the importance of litter input and soil extracellular phosphatase activity in driving seasonal soil P fluctuations, highlighting the need to study soil P dynamics as an integrated system in tropical ecosystems.

Summary: The study investigated the effects of different land-use types on soil P fractions and sorption-release characteristics in the eutrophic aquatic-terrestrial ecotone of Dianchi Lake. It found that different land use induced changes in soil P fractions and P stocks, with buffer zone soils showing higher P buffer capacity. However, despite the buffer capacity, there is still a high risk of soil P loss due to accumulation of available P in the soils.

Summary: In this study, P partitioning and speciation in Brazilian Cerrado Oxisols were investigated using sequential chemical P fractionation (SPF), P K-edge XANES, and 31P NMR spectroscopy. The results showed that P mainly sorbed to Fe and Al hydr(oxides), and organic P in soils under native vegetation existed primarily as phytate. Additionally, different management systems led to different P accumulation in the soil.

Summary: Responsible management of Acacia plantations requires understanding the trade-offs between maintaining stand production and reducing environmental impacts. Intensive drainage leads to increased carbon emissions, peat subsidence, fire risk, and nutrient export, while also enhancing nutrient availability for plant uptake. Dynamic process models can help comprehend the interconnected hydrology, stand growth, carbon and nutrient balance, and peat subsidence, informing production schemes that are environmentally and economically viable.

Summary: Soil chemical fertility in tropical and subtropical agriculture has declined due to depleted stocks of phosphorus, nitrogen, and carbon. This study used the APSIM model to simulate the dynamics of these elements and found that nitrogen supply and water availability strongly influenced crop yield and nitrogen export. The model also identified long-term depletion or accumulation of soil phosphorus, nitrogen, and carbon in most treatments. P fractionation and isotherm measurements were found to be labor-intensive but valuable, and efforts should be made to establish a database for different soil types.

Summary: The dynamics of juvenile plantation forest are complex, but understanding early growth and survival is crucial for effective management. Traditional growth and yield models provide essential information for decision-making in managing planted forests. The integration of explanatory factors such as wetness index and morphometric protection index can improve predictions and support forest management decisions. In this study, hybrid growth and yield approaches were tested for Eucalyptus species, with topographic and climatic factors enhancing height growth and survival prediction. These models can assist forest managers in making informed decisions for plantation establishment and management.

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: Fagus sylvatica L. is a competitive tree in European temperate deciduous forests, but often sporadic or absent in present-day stands where Quercus spp. are dominant. 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.

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.
