Summary: This study focused on stand biomass dynamic models of evergreen forests in order to improve biomass growth dynamic assessment at regional scale based on easily observable parameters. The results revealed that in managed forests, the thinned model showed better identifiability and support compared to the Mitscherlich model, while in self-thinning forests, the Bayesian inference results were in accordance with the self-thinning 3/2 rule.

Summary: The accepted paradigm in Australian forest hydrology is that streamflow from even-aged forests is influenced by forest age (the Kuczera curve), although this is less common in the Northern Hemisphere. However, none of the stand replacement experiments in Australian obligate seeder forests have faithfully reproduced the Kuczera curve. This study proposes an alternative model based on the self-thinning line, which explains the observed changes in self-thinning after disturbance and provides a better understanding of hydrological responses to disturbance.

Summary: The self-thinning law was applied to examine the density-dependent mortality in uneven-aged stands using data from forest inventory plots in Slovenia. The models developed for different stand types, including mono-species, multi-species, and single tree selection stands, showed variations in the slope and intercept of the self-thinning line. The species mixture and composition had an impact on the maximum stand density. These models are useful for understanding tree competition and growth in uneven-aged forests.

Summary: This article describes the development of growth models for the cypress species Hesperocyparis lusitanica and H. macrocarpa in New Zealand. These models, based on measurements from 521 sample plots, include height/age, diameter/age, mortality, and stand-level volume functions. They are valuable tools for forest managers in evaluating regimes and predicting yields. By accurately describing site productivity using the 300 Index, these models provide an improved framework for understanding and quantifying site productivity.

Summary: Rotation forestry has been the main management practice in Finland, but the existing models are mainly applicable to even-aged stands. With the increasing demand for continuous cover forestry, there is a need for models that can be applied to uneven-aged stands. However, the new height-dbh models have shown less accurate performance compared to the existing models for even-aged stands.

Summary: Self-thinning dynamics are often considered in forest management to constrain growth models. This study developed self-thinning relationships based on tree density relative to mean tree diameter, considering site quality and stand structure. The rates of self-thinning decreased as the proportion of the object species increased, relative height increased, and site index increased. The effects of aridity varied among species.

Summary: The aim of this study is to investigate the relationship between initial stand density and thinning intensity and tree diameter, height, and volume increment based on 30-year observations. The results show that the most intensive thinning plots had the highest diameter increment, 1.5 times higher than the control plots. However, increasing thinning intensity and signs of growth stabilization in control stands do not guarantee the highest productivity and cumulative volume in the future.

Summary: Understanding the spatial patterns and interactions of trees in forest stands is crucial for understanding forest development processes. In this study, we analyzed the temporal changes in tree spatial patterns in uneven-aged Douglas-fir dominated stands in British Columbia, Canada. Our results showed that unthinned plots had clustered spatial patterns, while plots with moderate and heavy thinning treatments had random or regular patterns. We also found that tree diameters were not spatially autocorrelated in thinned plots, but there was positive spatial correlation in unthinned plots. Dead trees were smaller in size and clustered at all spatial scales, and there was no spatial relationship between dead and surviving trees.

Summary: Thinning has a modest impact on the C balance of silver birch stands, resulting in decreased net ecosystem production but still maintaining as C sinks, mainly due to reduced tree biomass. Thinning increased C accumulation in herbaceous plants but did not compensate for the lower C accumulation by trees. Overall, thinning did not significantly affect soil respiration fluxes.

Summary: The number of species shared between sites decreases as more sites are included in the comparison, with a rate dependent on the most widespread species. In over 80% of empirical communities, the decline in shared species follows either an exponential or power law form, which are largely untested and poorly understood. Simulation results show that the distribution of widespread species differentiates the two forms, with the power law form favored when such species occupy more than 75% of sites. Empirical data confirms that the form of multisite similarity decline can predict community structures and competitive interactions.

Summary: People who walk in urban parks near water bodies like rivers, ponds, or lakes often suffer from mosquito bites, which can negatively impact their health and mood. Previous studies have focused on linear effects of landscape composition on mosquito abundance, but this study compares linear regression with a generalized additive model and finds that the latter provides a better fit by considering nonlinear relationships. The coverage of trees, shrubs, and forbs significantly influenced mosquito abundance, with shrubs having the greatest contribution. The addition of interaction between trees and shrubs improved the model's fit.

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: 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.
