Summary: The study reconstructed microbial succession along a land-freshwater-estuary continuum within La Romaine river watershed in Northeastern Canada, finding varying importance of assembly processes and shifting selection hotspots depending on hydrological conditions. The majority of the reactive pool could be traced to soil/soilwater-derived taxa, while the unreactive fraction was composed of taxa with diverse potential origins, highlighting the importance of upstream history and hydrological seasonality in understanding microbial community assembly on a network scale.

Summary: The study investigated the dynamics of microbial diversity and functional groups during forest succession in boreal ecosystems. Shifts in microbial community composition were found, with fungi being more sensitive to changes during succession. Ectomycorrhizal fungi showed a significant increase in relative abundance, suggesting a key role in nutrient cycling processes in soil during succession.

Summary: This study evaluates the changes in beta-diversity of saproxylic beetle communities during deadwood succession and identifies the major drivers of these changes. The results show that beta-diversity of saproxylic beetle communities increases over time and is positively correlated with phylogenetic distance between tree species and spatial distance among regions. The effects of spatial distance, climate, and forest structure remain constant throughout the succession process. The diversity of saproxylic beetles can be enhanced by promoting forests with diverse tree communities and structures.

Summary: In the context of global change, this study analyzed the ecological processes driving forest recovery in fire-modified landscapes by studying changes in functional and phylogenetic composition over 8 years. Environmental filtering and light limitation were found to be major drivers of community assembly, with faster changes at the forest edge compared to the interior. The study highlighted deterministic assembly processes in tropical forest post-fire succession, with fire and drought driving environmental filtering during early succession.

Summary: Fire plays an important role in hemi-boreal forest succession, structure, and biodiversity. This study focused on Lithuania's forests and used the ASIO model to map the potential natural fire regimes. Dendrochronological records were used to analyze fire occurrence in a fire-prone forest landscape. The findings highlight the impact of both human and natural fires on the landscape.

Summary: Many studies have shown that assembly mechanisms may differ between life stages, and ontogenetic dependency plays an important role in determining the composition of different life stages. In this study conducted in a forest dynamics plot in California, it was found that adult plant diversity was mainly influenced by spatial factors, while seedling diversity was mainly explained by ontogenetic dependency.

Summary: The study assessed the long-term impacts of selective logging and active restoration on tree species diversity, community composition, and forest structure for biomass recovery. Results showed that basal area and pole stem density were lower in logged forests compared to unlogged forests, but no difference in stem density was found for saplings and established trees. Logging had a negative impact on sapling species diversity, while tree species composition differed significantly between logged and unlogged forests across all stem size classes.

Summary: This study investigated the effects of climate, tree species composition, and other environmental variables on boreal forest regrowth following clearcut logging in eastern Canada. It predicted a beneficial, but limited effect of projected climate changes on forest regrowth rates, with conifer forests being more positively affected compared to mixed and broadleaved forests. The predicted increased regrowth rates were mainly associated with increased temperature, while changes in climate moisture had a minor effect.

Summary: North American boreal forests have suffered extensive tree mortality and carbon loss due to stand-replacing disturbances, but the impacts on forest dynamics are still unknown. This study used remote sensing data and biomass datasets to estimate the effects of fires, logging, and insect outbreaks on the carbon balance of western North American boreal forests. The results showed significant losses in aboveground biomass for all three disturbances, with fire being the dominant factor for forest recovery. Environmental factors also played a role in forest recovery. These findings have important implications for effective forest management after disturbances.

Summary: This study found significant impacts of storm disturbance and post-storm management on understory vegetation. Salvage-logged plots showed the highest coverage and species richness of herbaceous plants, but no significant effect on diversity or evenness. Approximately two decades after the storm, understory communities differed significantly due to different management practices.

Summary: Changes in organic carbon composition affect the composition and structure of soil bacterial communities during forest succession. Stochastic assembly is the dominant process, with higher bacterial nodes and connectivity in the organic horizon. There is a significant relationship between organic carbon composition and bacterial communities, with differences observed in the organic horizon and mineral horizon.

Summary: Species with wider geographical ranges tend to have higher physiological tolerances to environmental challenges, which may enable them to expand their range more easily. Physiological data can be useful in predicting a species' potential range size and vulnerability to anthropogenic disturbances.

Summary: Landscape complexity plays a key role in determining the population dynamics of interacting predators and prey. The commonly used aspatial predictive models in management plans may lead to unexpected outcomes or missed opportunities for spatial interventions. By utilizing spatially explicit individual-based models, it is possible to manipulate species interactions and achieve specific management goals related to predation rates.

Summary: The disturbance hypothesis suggests that habitat disturbance promotes the invasion success of non-native species. This study aimed to investigate the effects of anthropogenic disturbance (logging) occurrence, intensity, and time since logging on the invasion success of the non-native slug species complex Arion subfuscus s.l. The results showed that logging occurrence had a positive effect on Arion abundance in only one of the study sites, while having a negative or no effect in the other sites. Additionally, Arion abundance decreased with increased biomass removal intensity and generally increased with time-since-logging. Future studies should aim to reformulate the disturbance hypothesis to make more specific predictions about the conditions under which habitat disturbance promotes the invasion success of non-native species.

Summary: Although global change can reshape ecosystems, indirect interactions remain overlooked. Climate and land-use-induced changes in landscape affect food webs. Using simulations, we predict the outcomes of global change on a large-mammal food web in the boreal forest. Our results show that changes in forest landscapes exacerbate apparent competition between moose and caribou populations through wolf predation, with the cumulative effects of land use and climate change amplifying caribou mortalities.
