Toxins deposited during heartwood formation (extractives) are largely responsible for its durability and can be quantified by chemical extractions and well-replicated comparisons of sapwood and heartwood densities. Using the latter approach, we explore variation in heartwood attributes of the tallest species, <em>Sequoia sempervirens</em>, in secondary forests regenerating post logging in California. After climbing, measuring, and core-sampling 77 dominant trees (96–202 yr old, 56–87 m tall, 6–37 Mg biomass) in 18 locations distributed from northern rainforests to warmer, drier, and less foggy margins of the species range in California, we combine improved allometry with dendrochronology to reconstruct tree sizes for developmental analysis. Northern trees have the lowest wood densities, highest wood volume increment, fastest increase in the heartwood proportion of wood volume increment, highest growth efficiency (biomass produced per unit leaf mass), and lowest extractive proportion of heartwood increment, whereas marginal trees are at the opposite extreme and central trees are intermediate in all these metrics. In the climatically distinct and fire-prone canyons of the marginal range, higher density and extractive content of heartwood contribute to long-term carbon sequestration and persistence of <em>Sequoia</em>-dominated vegetation. Allowing <em>Sequoia</em> to reach great height may be the best way to improve carbon sequestration in the core range, where heartwood extractive content and decay resistance are lower in secondary forests than primary (old-growth) forests. Biophysical constraints on turgor pressure in lofty crowns may limit sapwood production and promote heartwood deposition throughout the trunk, explaining why tall trees in primary forests have higher heartwood extractive content than much shorter trees in nearby secondary forests. Understanding the causes of regional variation in heartwood attributes requires further study, including outside California where <em>Sequoia</em> is widely planted for its extraordinary values.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"593 ","pages":"Article 122926"},"PeriodicalIF":3.7,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144366913","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}

Norway spruce (<em>Picea abies</em> (L.) H.Karst) stands in the Central Europe are declining due to climate change, necessitating alternative silvicultural strategies. Silver fir (<em>Abies alba</em> Mill.), shade-tolerant species with the potential to form multi-storey stands, has been proposed as a potential replacement. However, its response to warming in spruce-dominated stands remains unclear. This study presents results from a three-year in situ climate experiment in the Western Carpathians, where soil warming of 0.5 °C simulated future climate conditions. Dendroclimatic and biogeochemical approaches were used to assess the effects of warming on the growth and nutrient status of young silver fir trees, growing as a young generation in a decaying spruce stand. Results indicate that while initial height and diameter growth were not significantly affected by warming, a declining growth trend emerged after three years, suggesting that temperature conditions exceeded the species' optimal range. Furthermore, warming reduced main macro- and micronutrient concentrations in fir needles, especially calcium (Ca), phosphorus (P), potassium (K), magnesium (Mg), copper (Cu) and manganese (Mn), which are essential for physiological processes and stress resistance. Stoichiometric analyses revealed shifts in carbon (C), nitrogen (N) and P ratios, indicating possible nutrient imbalances. The results highlight the vulnerability of young fir trees to warming and suggest that future forest adaptation strategies must consider both physiological responses and site conditions.

The MaxEnt model results exhibited high simulation accuracy, and the predicted suitable areas conformed with real growth and distribution patterns. The annual mean temperature (BIO17) and precipitation of the driest quarter (BIO01) were the primary climate factors influencing &lt;em&gt;Picea&lt;/em&gt; dispersion. The total suitable area during the LIG period was 7.43 × 10&lt;sup&gt;7&lt;/sup&gt;km², which represents 93.34 % of the current total suitable area. The total suitable area during the LGM represents 76.31 % of the current total suitable area. The total suitable area during the MH represents 96.11 % of the current total suitable area. Under future climate scenarios, the total potentially suitable area exhibited a marginal increase of less than 3 %, while the highly suitable area experienced substantial reductions. Specifically, under RCP6.0, the highly suitable area decreased by 11.65 % and 13.60 % compared to current conditions. The most pronounced declines occurred under RCP8.5, with highly suitable area shrinking by 15.46 % and 20.41 % in the 2050 s and 2070 s, respectively, compared with that under the current scenario. Under future scenarios and among the 31 &lt;em&gt;Picea&lt;/em&gt; species, the total suitable area for 22 species indicated a decreasing trend with the greatest decrease under the RCP8.5 scenario.

Decomposition of each litter species declined in a close to linear way throughout 36 months of exposure, with decomposition of beech leaves being slowest.

Immediate logging had the greatest negative impact on soil temperature variables, with maximum daytime soil temperatures increasing by up to 3.5°C in the topsoil (10 cm) and diurnal temperature variation rising by up to 1.9°C.

In addition, delaying salvage logging, or opting for no salvage logging, resulted in an 8–11 % increase in soil water content compared to the control.

In forests, canopy cover and structure shape microclimatic conditions and habitat features, yet little is known about how these characteristics affect carrion decomposition by vertebrate scavengers. As forest disturbances increasingly open up canopies, understanding the impact of canopy cover on carrion decomposition becomes essential. We investigated removal rates of small carrion at paired gap and closed-forest plots along a gradient of forest-management intensity in three regions in Germany, using camera traps to monitor vertebrate scavengers. Of 89 rat carcasses, 67 were removed by vertebrates. Initial removal rates were higher in gaps than in closed forests and at plots with higher forest-management intensity. However, over the full exposure time, removal rates were similar across all treatments. Differences in temporal patterns of carrion removal were linked to shifts in scavenger dominance, with red kite (<em>Milvus milvus</em>) prevalent in gaps and red fox (<em>Vulpes vulpes</em>) in closed forest. Our findings indicate that forest management and changes in canopy cover, such as those caused by disturbances, have little impact on carrion removal rates. Vertebrate scavenger assembly however differed between open and closed forests, which suggests functional redundancy among scavengers but that it is important that carrion resources are available for scavengers both in gaps and closed forests to promote overall biodiversity and maintain their ecosystem functions.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"593 ","pages":"Article 122920"},"PeriodicalIF":3.7,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306415","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}
