Summary: Outbreaks of defoliator insects, such as the forest tent caterpillar, can have short-term effects on soil springtail communities, causing shifts in composition. However, these communities ultimately show resilience and recover over time.

Summary: The oak-pine forests in the U.S. Central Hardwood Region are recovering from past exploitation and experiencing rapid succession changes. A study on red oak borer outbreaks and their interaction with climate change revealed that succession plays a more crucial role than climate effects and insect disturbances in predicting regional species composition changes. The modeling approach used in the study improved the realism of simulating insect disturbances and provided insights for decision-making in forest management plans.

Summary: The study found that hickories may have a conservative root-centered growth strategy that exceeds that of oaks, with highly plastic physiology. This allows for long-term persistence of hickories in the mid and understory while being responsive to favorable increases in available light. The reproduction dynamics of hickories suggest a gradual and consistent recruitment to the mid and overstory in contrast to the single, unimodal age distribution of oaks following historic disturbance.

Summary: The Forest Inventory and Analysis (FIA) program of the U.S. Forest Service aims to estimate various forest attributes using a design-based network of sampling plots. This study explores the use of digital aerial photogrammetric (DAP) point clouds developed from stereo imagery to improve these estimates in southeastern mixed hardwood forests. The results show that using the DAP point clouds improved the precision of forest volume estimates compared to using tree canopy cover data.

Summary: Managing old-growth forests and promoting old-growth complexity in aging forests for carbon emissions mitigation has become an important component of diversified land management strategies. Understanding carbon storage potential in old-growth forests across the Central Hardwoods Region (CHR) is crucial for evaluating climate-adaptive management strategies. The study found that old-growth forests on more productive sites in the eastern portion of the CHR stored more aboveground carbon than less productive sites to the west. Over a twenty-year period, old-growth forests in the region accumulated 7% more total aboveground carbon, with varying impacts on different carbon pools.

Summary: In many regions of the world, excessive browsing by ungulates has reached unsustainable levels, threatening biodiversity and forest regeneration. Moose, as ecological engineers, have severe impacts on forest structure and composition through overbrowsing. The distribution of forage and cover patches affects moose browsing pressure, and this relationship has been explored in conifer-dominated stands but not in hardwood-dominated landscapes.

Summary: In 2016, mixed-severity wildfires in the southern Appalachians provided a unique opportunity to study forest structures and breeding bird response. Over a period of 5 years, the researchers measured the forest structure and breeding bird communities across a fire-severity gradient. The results showed that high-severity burns had the greatest impact on tree mortality, shrub recovery, and breeding bird abundance, richness, and diversity.

Summary: Overall, Pinus, for conifers, and Quercus, Juglans, Fraxinus for hardwood species showed the most balanced ratio between basal area increments (BAI) and intrinsic water-use efficiency (iWUE), making them preferable for forestry plantation in areas with increasing drought risk. However, regarding specific species like Populus and Cupressus, there were clear distinctions in iWUE and BAI accumulation.

Summary: This study aims to use a combination of LiDAR and satellite imagery to identify and differentiate the structural features of old-growth forests. The results show that undisturbed old-growth forests exhibit intermediate characteristics in terms of structure, while transition old-growth forests and disturbed old-growth forests have distinct features.

Summary: This study used wearable devices to monitor the concentrations of urban particulate matter (UPM) in northern China during the heating and non-heating seasons. By analyzing multiple factors, including temperature, humidity, land use, and point-of-interest data, the study revealed the spatial-temporal distribution and influencing factors of UPM. The results provide valuable insights for urban planning and health risk reduction.

Summary: The composition, abundance, species richness, and diversity of the herb-layer community are influenced by nitrogen fertilization, disturbance history, and the overstory tree species nearby. Fertilization lowered diversity indices, while older unfertilized watersheds had higher diversity than younger ones. The presence of sugar maple was associated with higher herb-layer cover and diversity indices in some watersheds, despite differing watershed aspects.

Summary: Natural disturbances play a key role in shaping forest ecosystems, and assessing disturbance regimes is crucial for understanding forest dynamics and biodiversity habitats. A study on beech-dominated mixed forests in the Western Carpathians revealed a predominance of windstorms as the main disturbance agent, with significant spatial and temporal variability in disturbance events, particularly in the mid-19th century.

Summary: Previous studies have shown that the impacts of harvest on stream chemistry in deciduous forests with seasonal snow cover vary and may take different recovery times. In this study, we investigated the interactive effects of forest harvesting with regional and global environmental changes on stream solute concentrations and other parameters. The results showed that the impacts of harvest on stream chemistry were greatest in clearcut areas, moderate in selection cut areas, and least in shelterwood cut areas. The impacts typically lasted for one to six years, although some solutes were impacted for the entire 21 year post-harvest period. Different solutes showed different response patterns, which were consistent with expected changes in nutrient demand, sources, and transport due to harvesting. Comparing harvest impacts to long-term climate change and acidification recovery revealed antagonistic or synergistic effects depending on the solute. These findings highlight the importance of long-term monitoring to accurately understand the consequences of forest harvesting practices in the face of environmental change.

Summary: Oak is being replaced by maple in the eastern deciduous forest. Prescribed fire has been used to deter this replacement, but its effectiveness has not been comprehensively evaluated. This study surveyed oak-dominated stands in two National Forests and found that repeat applications of prescribed fire increased oak regeneration, but only with concurrent treatment of midstory stems.

Summary: In this article, a machine learning algorithm based on the GOES-16 ABI sensor is developed to detect and monitor active fires in real-time in the MATOPIBA region. The final model achieved an overall accuracy rate of approximately 80% and reached its peak accuracy after about 20 hours of consecutive active fire detections.
