Summary: The structure, composition, and functional changes of the P. pinaster rhizosphere bacterial communities vary with seasons, without being influenced by the host genotype. Seasonal changes are reflected in the patterns of bacterial co-occurrence, suggesting potential disturbances for bacterial communities in the context of climate change.

Summary: The study validated a fast liquid chromatography-mass spectrometry method for quantifying phytohormones in Pinus pinaster tissues. Results showed significant increases in salicylic acid and jasmonic acid methyl ester in susceptible phenotypes, indicating higher susceptibility of Pinus pinaster to PWN infection might result from an inefficient trigger of immune responses.

Summary: This study employed proteomics and metabolomics to investigate bud maturation in Pinus pinaster, identifying specific proteins and metabolites involved in epigenetic regulation, hormonal signaling, and abiotic stress pathways. These findings enhance our understanding of the molecular processes behind bud maturation, offering valuable insights for timber production and forest management in the face of climate change. Further research using different pine populations is needed to validate and generalize the results.

Summary: The pinewood nematode (PWN) is a major threat to conifer forests, causing pine wilt disease (PWD). Research on susceptible and resistant maritime pine (Pinus pinaster) plants revealed that susceptible plants shut down central metabolism, accumulate osmolytes, inhibit photosynthesis, and decrease water status after PWN inoculation. In contrast, resistant plants showed a regulated defense response, restricted PWN migration, and accumulated certain metabolites like GABA and succinate, providing insights into mechanisms for disease resistance and selection of resistant phenotypes for forest breeding programs.

Summary: Through studying three different pine species in southern Europe, it was found that climatic patterns have species-specific differences in influencing tree growth. The Atlantic Multidecadal Oscillation and North-Atlantic Oscillation were identified as important drivers of tree growth, highlighting the importance of considering species-specific responses to climatic variability.

Summary: Pinus pinaster forestry has a significant impact on the national economy in Portugal, but oleoresin production has decreased due to competition from low-cost producers in other countries. The chemical composition of rosin derived from Pinus pinaster in Portugal is consistent regardless of forest location, with abietic acid and dehydroabietic acid as the major components.

Summary: This study investigated the sorption processes of dead Pinus pinaster branches (PPBs) to develop a moisture content prediction model for this fuel type. Laboratory tests were conducted to determine sorption curves, timelag, and equilibrium moisture content (EMC), and existing sorption models were used for modeling. Field tests in central Portugal validated the accuracy of the models. The developed model can be applied in early fire risk assessment.

Summary: This study analyzed the impact of using genetically improved forest reproductive material (FRM) on wood production and financial performance in four European case studies. It was found that the use of improved FRM led to better financial performance compared to planting unimproved material, across different wood price contexts. However, challenges remain in the economic assessment of realized gains from genetically improved FRM.

Summary: The study found that irrigation negatively affected SOC stocks in the forest floor, but had a positive influence on SOC in mineral soil, especially at 15-30 cm depth. Mixing tree species and irrigation increased SOC stocks in the short term, with positive effects observed at mid-soil depths. Root niche partitioning in mixed plots and increased tree biomass in irrigated plots contributed to greater organic matter inputs, suggesting that SOC dynamics are strongly influenced by soil depth.

Summary: Leaf Area Index (LAI) serves as a key ecological indicator for describing canopy structure and modeling energy exchange between atmosphere and biosphere. While LAI of the forest overstory can be accurately assessed via remote sensing, LAI of the forest understory (LAI(u)) remains challenging to obtain and has been largely ignored in ecological studies. Research on retrieval methodologies for understory LAI demonstrates significant correlation between different methods, but biases depending on the LAI scale are observed.

Summary: Understanding the critical soil moisture threshold is crucial for evaluating drought impacts and improving climate models. In Europe, estimating this threshold is challenging, but analyzing relationships between evaporative fraction, vapor pressure deficit, and gross primary production can provide valuable insights. Variations in surface energy partitioning and sensitivities to soil moisture were observed across different vegetation types.

Summary: Accurate determination of canopy conductance (g(s)) is essential for understanding water and CO2 exchange in forest canopies. This study used measurements of leaf-to-air vapor pressure difference and tree transpiration to calculate canopy g(s) in a pine forest. Different methods were compared, and it was found that they agreed under certain conditions but showed discrepancies under water stress conditions. The study also emphasized the importance of in situ surface temperature measurements for understanding canopy responses to environmental conditions.

Summary: Previous studies have shown that tree species diversity can enhance forest productivity and nutrient cycling. However, the effects of mixing tree species on stand-level nutrient use efficiency (NutUE) have been rarely studied, especially in the context of climate change. This study examines how the effects of species diversity on NutUE are modified by water availability and drought conditions. The results suggest that species composition of tree mixtures is more important than water availability for stand-level NutUE in young forest communities.

Summary: This study assessed the effects of different intensities of biomass harvesting and compensation methods on forest functioning. It found that additional biomass harvesting had negative consequences on the ecosystem biogeochemistry, leading to soil impoverishment and decreased soil organic carbon content. However, the application of phosphorus fertilizer or wood ash improved tree nutritional status, but did not fully compensate for the negative impacts of biomass exports.

Summary: This study investigates the effects of phosphorus fertilisation, understory removal, and their interaction on carbon storage and soil enzyme activities in two moorlands planted with maritime pines. Results show that in wet moorlands, fertilisation and understory removal have a positive effect on tree biomass, but do not affect soil carbon stocks or enzyme activities. In dry moorlands, understory removal has a positive effect on tree biomass but decreases topsoil organic carbon stocks and enzyme activities. Overall, the study highlights the importance of adapting forest practices based on environmental context and carbon sequestration objectives.

Summary: Litter decomposition is influenced by environmental factors, substrate quality, microbial communities, and N deposition. Climate impacts on global-scale decomposition are general but become more significant as decomposition progresses, while N deposition effects are litter-specific and significant in certain biomes. Climate changes are expected to increase litter mass loss, while N deposition changes may dampen climate-driven increases in decomposition, depending on biome and substrate stage.
