Summary: This study examines the impact of introduced parasitoids and native woodpeckers on the population growth of emerald ash borer infesting regenerating ash saplings. It reveals that Tetrastichus planipennisi Yang and woodpeckers contribute significantly to the mortality rate of emerald ash borer larvae. The study suggests that biocontrol measures can help promote the survival of young ash trees as forests recover from emerald ash borer outbreaks.

Summary: The persistence of mature ash trees and the development of regenerating ash trees have a significant impact on future forest composition and ecosystem structure. The initial infestation of emerald ash borer and the introduction of biological control agents provide unpredictable protection for mature trees but may safeguard the next generation of ash trees. A study conducted in eastern and western New York, ten years after the first detection of emerald ash borer and nine years after the release of parasitoid wasps for biological control, revealed changes in the composition and status of historically ash-dominated forest stands.

Summary: The invasive insect Emerald ash borer (EAB) poses a major threat to ash trees in North America. To conserve the genetic resources of ash trees, scientists have studied the effect of systemic insecticides on seed infestation and germination. The results suggest that using systemic insecticides can effectively reduce seed weevil infestation in ash trees without affecting seed germination rates.

Summary: Quantified changes in ash tree demography and emerald ash borer carrying capacity in forested ecosystems reveal significant impact of EAB invasion, with most ash trees dead post-invasion and EAB carrying capacity drastically reduced. Presence of live stump sprouts on EAB-killed green ash trees varied, while ash sapling and recruit density showed variability. Absence of newly germinated ash seedlings suggests potential limitations on recruitment of ash saplings and seedlings in post-invasion forests.

Summary: The emerald ash borer has caused significant damage to ash trees in North America, resulting in the death of hundreds of millions of trees. This study investigated the wood-degrading potential of Basidiomycota fungi associated with EAB galleries. The results showed that many of the white-rot fungi isolated were aggressive wood degraders, with Trametes versicolor, Phlebia radiata, and Phlebia acerina being the top decomposers, leading to substantial weight loss and degradation of wood cell walls.

Summary: The use of systemic insecticide treatments as a primary control strategy against emerald ash borer (EAB) may have nontarget effects on other insect species. This study assessed the effects of systemic injections of emamectin benzoate or azadirachtin on the spring and fall phenology of mature green ash trees. The results suggest that systemic insecticides may mitigate changes in ash tree phenology such as delayed leaf out that may be early symptoms of EAB.

Summary: The study highlights that planting susceptible non-native host plants can induce outbreaks of a native insect pest in its native range, potentially increasing the risk of invading novel regions via human-assisted activities such as international trade. The research also suggests that there may be lag-times of several decades between planting susceptible hosts and initial pest outbreaks, posing challenges in predicting the true risk of invading novel regions. Therefore, a comprehensive risk assessment for invasive insect pests should consider the role of non-native plants introduced or planted in the pest's native range.

Summary: Invasive forest insects have significant impacts on forest ecosystems and forest landowners. This study found that the detection of highly impactful emerald ash borer (EAB) decreases the probability of harvest but increases the intensity of harvest, resulting in a net increase in harvested biomass. Furthermore, EAB detection influences private landowners to harvest greater quantities of ash and affects the diameter of harvested trees.

Summary: Emerald ash borer (EAB) invasion impacts riparian ecosystems by creating canopy gaps and altering bacterial communities. Downstream of EAB-related canopy gaps, dissolved oxygen and macroinvertebrate diversity decreased, while there was no difference in coarse woody material or aquatic leaf litter. Organic matter dynamics remained resistant to change, likely due to downstream movement of organic matter from upstream sources.

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: This study examines the influence of canopy structure on tropical tree growth using data collected through unmanned aerial vehicles (UAVs) and field measurements. The results show that combining UAV and field data can improve the prediction of tree diameter increment. Diameter at breast height and crown area are complementary predictors, and crown-based competition indices significantly enhance prediction models. The calibrated model at one site can accurately predict growth at another site.

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.

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.
