Summary: Ecology still cannot fully explain why so many tree species coexist in natural communities, with a major difficulty being linking individual-level processes to community dynamics. By using tree spatial data, spatial statistics, and dynamical theory, the relationship between spatial patterns and population-level interaction coefficients can be revealed, impacting multispecies dynamics and coexistence.Mechanisms such as animal seed dispersal lead to a rare-species advantage and coexistence of otherwise neutral competitors.

Summary: The study experimentally tested the role of a generalist enemy in promoting the coexistence of competing insect species and found idiosyncratic impacts, without evidence of an overall trade-off between reproductive rate and susceptibility to enemies. Modern coexistence theory proved valuable in multi-trophic contexts, but unable to easily predict the overall impact of generalist natural enemies. The Bayesian approach highlighted the separability issues in model parameters and demonstrated the utility of using the full posterior parameter distribution for understanding species coexistence.

Summary: The study found that tiger occupancy was influenced by the availability of remnant sambar, while leopard occupancy was related to the presence of wild pig. Contrary to the hypothesis, leopards were not completely excluded from tiger-occupied zones, but their detectability was significantly lower, indicating fine-scale avoidance behavior.

Summary: The distribution of fruit pigeons on the island of New Guinea is influenced by geographical accessibility. The coexistence of species in a particular year and location is a nonrandom selection process. The sizes of these species are more widely spread and evenly spaced compared to random sets of species. Additionally, the local status of a highly mobile species decreases as other resident species become more closely related.

Summary: This study analyzed the fine scale spatial pattern of Moroccan fir and Cedrus atlantica in a mixed forest in northern Morocco, revealing an aggregation of conspecific and heterospecific individuals at small distances up to 2m. Recruitment of A. marocana mainly occurred close to dominant trees of C. atlantica, while C. atlantica dominated in small gaps. The spatial patterns observed suggest attraction mechanisms between the two species.

Summary: The exploration of mechanisms that enable species coexistence under competition for a sole limiting resource is a common topic in ecology. Intraspecific competition and spatial self-organisation are two important processes that facilitate coexistence, and their interplay forms a mechanism that does not rely on species-specific assumptions and captures coexistence across different environmental stress gradients.

Summary: Mutualisms are important in maintaining biodiversity, but are not currently included in existing coexistence theory, leading to potential errors in assessing how mutualisms affect the coexistence of competing species. The author develops a theory predicting how multitrophic mutualisms mediate species coexistence and demonstrates the importance of considering mutualisms in evaluating coexistence consequences.

Summary: In this study, we measured stomatal density and position of 90 widespread plants on the Loess Plateau, and analyzed the spatial patterns using replicated spatial point pattern analysis. The results showed that stomatal distribution pattern was similar in most plants, except for five species. Stomatal density and distribution were influenced by phylogeny and spatial scale, with regular distribution at small scales and random distribution at large scales. These findings provide insights into the relationships between stomatal distribution and phylogeny, which can inform the optimization of transpiration models in the future.

Summary: This study investigated the spatial distribution patterns and survival ability of sprouting trees in the karst old-growth forests of Maolan National Nature Reserve in China. The results showed that sprouting trees tended to cluster together with alive trees and were influenced by unseen factors. The diameter of sprouting trees was related to their survival rate, and trees with similar diameters were more likely to form clusters. Furthermore, microsite conditions played a crucial role in the regeneration and rapid growth of sprouting trees.

Summary: This paper provides an analysis of a mathematical model for two competing species in a chemostat, where they feed on a single resource and the dominant species can flocculate. The existence and uniqueness of positive solutions to the single-species model with flocculation are established. Furthermore, the study shows that when the superior species flocculates, there can be coexistence of all species for small attachment.

Summary: Theory suggests that competing species can coexist in a community when intraspecific competition is stronger than interspecific competition. This study found that the evolution of species- and size-dependent competitive asymmetries increased the likelihood of coexistence between interacting species. Furthermore, the research highlights the importance of integrating evolution and trait-based interactions into studies on species coexistence.

Summary: Forest gaps play an important role in temperate forest ecosystems. This study investigated the spatial distribution and replacement patterns of woody plants between primary and secondary forests during the gap-filling processes in Northeast China. The results showed that gap age, competition between species, and pre-existing regeneration status led to different species replacement patterns. Gap formation increased species richness, but only a small percentage of the species successfully reached the upper layer. The study provides insights into the competition dynamics among tree species during the gap-filling processes.

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: Managed forests serve as a natural climate change solution by sequestering carbon and storing it in harvested wood products, while also providing ecosystem services and wildlife habitat. This study focused on the stem sinuosity of juvenile coastal Douglas-fir and found that genetic improvement, silviculture practices, and local growing conditions can impact stem sinuosity. Factors such as tree spacing, vegetation control, and climate variables also affect the severity of stem sinuosity.

Summary: The study aimed to assess the effects of different forest management strategies, dead wood types, and microclimates on Fomes fomentarius. The results showed that the occupancy of Fomes fomentarius was lower in control stands, while the percent cover occupied on snags under a closed canopy was higher. Increasing the number of snags and maintaining dense forest canopies could enhance the presence of Fomes fomentarius as well as provide important microhabitats for various arthropods.

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.
