The plantations dating from 1990 were thinned in 2008. First, disk samples collected in 2021 from 140 trees across the four thinning intensities were used to construct a ring-density model following thinning. The plot inventory data from 2008, 2014, and 2021, combined with the ring-density model, were then used to estimate individual tree carbon sequestration, which was summed at the plot level. We found that (1) ring density displayed higher values near the pith, followed by a rapid decline, after which ring density slightly increased toward the bark; (2) thinned and control treatments showed similar average ring-density chronologies throughout the study period, constraining the generalization of post-thinning ring-density trends; and (3) thinned plots exhibited lower tree CO<sub>2</sub> sequestration rates than control plots, with estimates of 5.17, 5.35, 4.75, and 5.84 t·ha<sup>−1</sup>·year<sup>−1</sup> for 100 crop trees per hectare, 50 crop trees per hectare, thinning from below, and the control respectively.

Climate change projections for the Great Lakes region (USA) point to expansion of deciduous broadleaf species at the expense of conifers, as well as decreased winter snowpack thicknesses. To assess the sensitivity of the soil CH<sub>4</sub> sink to forest composition, winter snowpack thicknesses, and soil frost, we conducted a 2-year snow removal experiment in sandy soils. The sites were dominated by either sugar maple (Acer saccharum) or red pine (Pinus resinosa) in northern Michigan, USA. We measured in-situ CH<sub>4</sub> uptake using static chambers in plots where snowpacks were either left undisturbed or removed. Our results indicate that annual soil CH<sub>4</sub> uptake is 25–30 % higher under sugar maple than under red pine, suggesting that predicted broadleaf forest expansion will increase the strength of the soil CH4 sink. Nonetheless, our estimates of annual CH<sub>4</sub> budgets for these stands also indicate that this process may only contribute 2–3 % of the annual climate mitigation services in these forests. We observed no differences in rates of wintertime CH<sub>4</sub> uptake between treatments, and no carry-forward effects of snow removal on rates of growing season CH<sub>4</sub> uptake. Depth trends in soil CH<sub>4</sub> concentration indicate that wintertime CH<sub>4</sub> uptake in our control treatment was limited primarily by the rate of diffusion of atmospheric CH<sub>4</sub> through the snowpack and into the soil, whereas it appears that CH<sub>4</sub> uptake in our removal treatments was limited by soil freezing.

We link compositional shifts to demographic processes such as recruitment, growth, and mortality, providing a clearer understanding of succession dynamics.

The impact of tree species composition on plot-level responses was observed for drought resilience components at the drier site. Additionally, plot diameter heterogeneity positively influenced growth resistance to both stressors, while basal area negatively affected drought resistance. Water balance played a central role in the growth of both species, but silver fir growing in drier conditions was less influenced than silver fir growing in wetter ones. Silver fir can adapt growth strategies to deal with different environmental settings.

The material was collected from young Scots pine (<em>Pinus sylvestris</em> L.) and Norway spruce (<em>Picea abies</em> (L.)

In the middle-aged stand after thinning, the residue levels were 0, 10, 20, and 30 Mg ha<sup>−1</sup>. In the young spruce stands, the removal of logging residue following the final felling resulted in a negative growth response, but the doubling of logging residue did not result in a further growth increase. In contrast, no treatment effects were observed in the growth of the Scots pine stands, both in the young stands after final felling and in the middle-aged stand after thinning. In the young stands after final felling, the logging residues had no significant impact on the amounts of humus layer C or N. In contrast, the logging residues increased the levels of both C and N in the humus layer of the middle-aged pine stand after thinning.

However, climate change may shift the geographic distribution of numerous tree species and alter the capacity of forest ecosystems to store carbon. The forests in the northeastern United States, characterized by their diverse tree species and complex structures, have experienced climatic changes in recent decades and are particularly vulnerable to these changes. Given that tree species vary in their carbon storage capacities, understanding how forest composition influences aboveground biomass (AGB) is crucial for assessing the impact of climate change on forest carbon storage. In this study, we synthesized plot-level forest inventory records (n = 27,858) to evaluate the influence of forest composition on AGB in the northeastern United States. Our results indicate that dominant tree species are the primary feature of forest composition most strongly correlated with AGB across all successional stages, exceeding the influence of species diversity and evenness. Projected climate warming in this region is likely to alter these dominant species. Although this shift may increase the abundance of hardwood species, which generally have higher wood density, the plot-level AGB is projected to decrease due to changes in forest structure introduced by the new dominant species. These findings highlight the important role of dominant tree species in determining forest biomass and suggest that warming-induced shifts in dominant species could reduce the carbon sequestration capacity of forests in the northeastern United States.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"580 ","pages":"Article 122536"},"PeriodicalIF":3.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143161779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In anurans and mammals, species composition changes between forest corridors and continuous forests were primarily driven by species replacement; while in birds, these changes were driven by differences in species richness.

The seedling and grass competition can affect seedling crown complementarity, a key canopy process that enhances the productivity of tree mixtures compared to monocultures by optimizing light capture and resource use. However, little is known about how their competition advantages shift from \"grass to seedling\" or \"seedling—grass—seedling\" or just grass. We conducted a four-year tree diversity experiment involving weeded versus unweeded treatments, with eight functionally divergent woody species comprised of 17 functional combinations. We examined how crown complementarity, crown volume, and stem basal area of tree seedlings varied between weeded and unweeded treatments along the gradients of tree species richness and functional diversity over time. Crown complementarity and crown volume of tree seedlings were positively affected by tree species richness and functional diversity, and the positive tree diversity effects on seedling crown complementarity strengthened over time under both weeded and unweeded treatments. On average, seedling crown complementarity was greater in unweeded than weeded treatments. Herbaceous plants increased crown volume but decreased stem basal area after three years, and the tree diversity effects on stem basal area were not significant in both weeded and unweeded treatments. Overall, herbaceous plants did not change the tree diversity effects on seedling crown complementarity, but mediated biomass allocation trade-offs between crown expansion and horizontal growth of stem in tree seedlings during the early stage of stand development. Our results suggest that herbaceous plants can boost seedling crown complementarity but their competitive effects are not large enough for affecting the positive tree diversity effects on seedling crown complementarity in the early stage of stand development.
