Summary: The distribution and genetic diversity of Beauveria isolates in northern European Russia boreal forests were studied, identifying three species and multiple haplotypes. Different subpopulations were found based on geographic location, suggesting intraspecific recombination across the region.

Summary: The study evaluated the impacts of restoration methods on forest stands in northern Sweden. Prescribed burning initially caused a decline in diversity but led to an increase in the long term for vascular plants, while ground layer bryophytes remained lower post-restoration. Gap cutting had no significant effects on diversity or community composition.

Summary: During the decomposition of organic matter, the assembly history, resource quality, and the arrival of primary and secondary colonizers can affect the composition of fungal communities and the rate of wood decay. The study found that the gradient of fungal community composition is related to resource quality and that the initial fungal community explains the variation in community composition. Additionally, the exclusion of invertebrates has a lasting impact on fungal communities.

Summary: In recent decades, European forests have been increasingly affected by natural disturbances, which have significant impacts on timber resources and ecosystem services. However, there is a lack of long-term empirical data and a coherent monitoring system to better understand disturbance dynamics and develop adaptive management strategies.

Summary: Reestablishing fire regimes in red fir forests can restore historical forest structure, with stronger effects observed in the Sierra Nevada region due to greater departure from reference fire return intervals and warmer, drier conditions. Incorporating historical references and regional fire return intervals is vital for the restoration of fire-dependent forests at local and regional scales.

Summary: Disturbances in forests can impact mycorrhizal fungal communities, affecting plant establishment and growth. This study found that soil transfers from late-successional forests did not alter resident fungal communities or seedling growth in disturbed stands. The presence and abundance of ectomycorrhizal fungi should be assessed before considering soil transfers for forest restoration.

Summary: The study found that aboveground biomass in boreal northwestern North America increased from 1984 to 2014, with losses from fires partly compensated by post-fire recovery, while losses from timber harvest were partly offset by post-harvest recovery. Earth system models overestimated biomass accumulation, indicating a need to improve representation of disturbance processes. Disturbance regimes like fire, drought, harvest, and insects are likely to intensify in the future due to climate change, impacting the carbon uptake and storage in boreal forests.

Summary: Understanding the long-term history of forest fires in boreal landscapes is crucial for studying the interactions between climate and fire, as well as the impact of human activities on natural fire regimes. This study reconstructs a 600-year fire history in a pine-dominated landscape in the Republic of Komi, Russia, and finds that climate plays a more significant role in shaping fire regimes compared to human activities.

Summary: Disturbances in ecosystems are changing due to climate change and human activities, leading to uncertain recovery of pre-disturbance ecosystems. In the boreal forest of western North America, intensifying wildfires are causing shifts from black spruce dominance to deciduous trees. Understanding the resilience and stability mechanisms of different community types is crucial for predicting future forest dynamics.

Summary: Spruce wood was modified by grafting poly(e-caprolactone) onto the wood cell wall using ring-opening polymerization. Different monomer concentrations (30%, 50%, and 70%) were impregnated into the wood and further polymerized in DMF solution. The biodegradability of the modified wood was tested through weight losses and analyzed through FTIR and SEM analysis. The results showed that higher concentrations of e-caprolactone exhibited better decay resistance against brown rot fungi attacks, while lower concentrations were more effective against white rot fungi attacks. SEM and FTIR analysis confirmed that weight losses were due to both cell wall degradation and polymer digestion by fungal enzymes.

Summary: Transformational change is needed to protect the world's natural resources. Ambitious forest restoration efforts are crucial in achieving this change, with the success of restoration depending on trees' ability to withstand various stressors, especially drought. Research often overlooks the significance of the former land use in determining the predisposition of trees to resist drought, potentially leading to wasted restoration efforts.

Summary: This study investigated the impact of different fire frequencies on soil systems and found that only the A horizon was significantly affected by the prescribed fire interval manipulation. The richness and composition of microbial communities in the A horizon differed between the burned treatments and the unburned control. Soil chemistry changes were also observed in the A horizon, with higher levels of certain nutrients in the burned treatments compared to the fire exclusion treatment. The results indicate that long-term changes in fire frequencies can induce shifts in the soil microbial community.

Summary: Sylvicultural practices, effective fire suppression, and increased browser densities have significantly changed structural diversity in boreal forests. Prescribed burning can enhance deciduous tree recruitment, especially for birch and rowan, while the impact of browsing on deciduous trees is age-dependent. Retention forestry combined with burning can reduce mortality rates for deciduous trees in managed forests.

Summary: This study analyzed the impact of moose on forest canopies across the boreal biome through distributed exclosure experiments. The results showed a uniform response of forest canopies to moose across regions, regardless of environmental gradients. Moose led to a decrease in canopy height, complexity, and above-ground biomass.

Summary: Deadwood is crucial for maintaining species diversity in forests, but forest management has resulted in its scarcity and a decline in biodiversity. This study investigated the effects of tree retention and prescribed burning on tree mortality and deadwood dynamics in Finnish boreal forests. The results showed that a combination of high retention levels and prescribed burning can generate diverse deadwood, which supports the conservation of deadwood-associated biodiversity in managed forests. However, the continuity of deadwood throughout the forestry rotation period remains uncertain, and management methods should be adjusted at the landscape level to ensure the persistence of deadwood habitats.
