By favouring the growth of early seral vegetation, they can increase the abundance and palatability of woody browse, a ‘browse subsidy’ that may attract ungulates like moose (<em>Alces alces</em>) and white-tailed deer (<em>Odocoileus virginianus</em>), the main prey of wolves. Peatlands traditionally served as refugia from wolves for boreal woodland caribou (<em>Rangifer tarandus caribou</em>), but such subsidies may facilitate disturbance-mediated apparent competition, whereby predator activity associated with deer and moose raises incidental predation risk to caribou. We tested this ’browse subsidy’ hypothesis by comparing availability and proportional use of palatable winter browse on seismic lines and adjacent undisturbed forest plots across a gradient from upland to peatland forest in the Athabasca oil sands region of Alberta, Canada. Seventeen seismic lines were sampled, each with four paired plots across an ecological gradient from upland to peatland. Each plot pair compared the seismic line with the adjacent undisturbed forest. Seismic lines averaged 5.0 more highly palatable stems per 10 m2 (61.5 % more) than adjacent forest plots, while the proportion of stems browsed by deer and moose was 59.2 % higher on lines and increased with browse stem density. However, even after accounting for increases in browse availability, browse use remained higher on seismic lines relative to the adjacent forest, indicating selection of seismic lines by deer and moose. These results suggest that browse subsidy on seismic lines may contribute to disturbance-mediated apparent competition and declines in caribou, particularly where subsidies occur in or adjacent to peatland caribou refugia. Targeted restoration of high-subsidy lines could reduce deer and moose activity in these areas and thus potentially reduce predation risk for caribou.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"606 ","pages":"Article 123554"},"PeriodicalIF":3.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146036225","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}

This study aimed to improve thermotolerance of “84 K” poplar tissue cultured seedlings by screening optimal ICE6 concentration and elucidating its mechanism. Phenotypic observation initially screened concentrations from 0.01 to 0.08 μg/mL, with 0.04 μg/mL selected. High temperature stress tests measured physiological indices (chlorophyll, root activity, malondialdehyde, osmotic substances, antioxidant enzymes). Integrated transcriptomic and metabolomic analyses, along with gene expression profiling, were conducted. Results showed 0.04 μg/mL ICE6 significantly promoted seedling growth. Under stress, it reduced MDA accumulation, slowed relative conductivity increase, and enhanced osmotic and antioxidant capacities. Transcriptomics identified 3789 differentially expressed genes, while metabolomics detected 819 differentially accumulated metabolites. Key genes correlated with dehydroascorbic acid and 2,3-diketo-<span>L</span>-gulonic acid. Mechanistically, 0.04 μg/mL ICE6 maintained membrane integrity, alleviated oxidative damage, boosted antioxidants, and upregulated sugars/proline. Regulation involved hormone signaling, phenylpropanoid biosynthesis, and flavonoid related antioxidant metabolism. This study represents the first application of ICE6 in the large-scale propagation system of poplar tissue-cultured plantlets, filling a research gap in the use of novel regulators for stress resistance in forest tree tissue-cultured plantlets. By analyzing key targets mediating heat tolerance via ICE6 at transcriptional and metabolic levels, it provides insights for genetic improvement of poplar stress resistance from these dual perspectives. Furthermore, this work lays a theoretical and technical foundation for directional regulation of stress resistance during industrial production of tissue-cultured plantlets, ultimately contributing to enhancing the resilience of forest ecosystems under climate change.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"606 ","pages":"Article 123532"},"PeriodicalIF":3.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146036236","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}

Because pollination services vary by species and across spatial and temporal scales, understanding the effect of fire on pollinator populations informs conservation management and ecosystem restoration. Due to the known positive effects of fire on bees, including increased floral resources, nesting habitat, and light availability, we hypothesized that pollinator richness would increase with burn severity (measured with the Composite Burn Index) and decrease with burn age. We quantified native bee richness in the Okanogan-Wenatchee National Forest in Washington, USA at nine forested plots that burned in 2021, 2018, and 2015, or were unburned since 1968. Data were collected in 2021, 2022, and 2023 biweekly from April to August using blue vane and pan traps. Our findings suggest that native bee genus richness was driven by the interaction between burn severity and burn age. Study areas that had recently burned at higher severities had greater bee genus richness. Furthermore, the proportion of above ground nesting bees in landscapes 1–8 years post-fire was greatest at sites that burned with moderate fire severity and had more available nesting habitat.

We monitored tree regeneration and browsing during 2012–2024 in permanent plots across De Hoge Veluwe National Park (the Netherlands) in transects as well as in exclosures paired with control plots. We found that food selection was not mediated by landscape-level characteristics, but rather by tree species identity. Tree species preferred by ungulates had less height growth when subject to browsing. Exclusion of ungulates led to a substantial increase in height growth of preferred species, while the relative height of avoided species was reduced, indicating apparent competition. Forest regeneration inside exclosures converged to a community of mixed broad-leaved species.

Cone harvest data reflects underlying reproductive cycles, but volumes are also influenced by seed demand and forest management decisions. Nevertheless, cone harvest remains a valuable proxy in forestry, as it reflects the availability of reproductive material essential for regeneration planning and nursery production. This comprehensive study analyzes the influence of temperature, precipitation, and the North Atlantic Oscillation (NAO) on the cone collection of seed material for four native Central European (Norway spruce, Scots pine, silver fir, European larch) and two introduced (Douglas-fir and grand fir) coniferous species. The quantity of cones harvested in the entire territory of the Czech Republic in 2004–2022 ranged from 78.7 to 396.9 t·ha<sup>−1</sup>·yr<sup>−1</sup>. The most intensively harvested tree species in the Czech Republic, Norway spruce (<em>Picea abies</em> [L.] Karst.), shows the most pronounced 2 and 3-year cycles, with a complementary 7-year cycle, with precipitation in April and October and lower temperatures playing a crucial role. Scots pine (<em>Pinus sylvestris</em> L.) dominates by 2.5 and 3.5-year cycles, influenced by precipitation in August and September and lower temperatures in September. Silver fir (<em>Abies alba</em> Mill.) shows 2.3-year cycles aligned with June precipitation, while European larch (<em>Larix decidua</em> Mill.) is influenced by the NAO, typically in 2-year cycles. Douglas-fir (<em>Pseudotsuga menziesii</em> [Mirbel] Franco) exhibits 2.2-year cycles linked to July precipitation and NAO in June, while grand fir (<em>Abies grandis</em> [Douglas ex D.

Of the forest tree species analyzed, Scots pine showed the highest correlation with the factors studied, while European larch had the lowest. The results show that tree seed crop cycles are strongly influenced by climatic fluctuations, which is essential for effective forest management. However, the 19-year dataset limits confidence in detecting longer-term cycles. Higher harvest volumes in species like Douglas-fir, grand fir and European larch are additionally affected by increased collection efforts. Understanding tree fructification cycles is crucial for planning, as climatic variations significantly affect reproductive success and the availability of planting material.

Here, we selected an expansion gradient in a natural forest region in southern China, consisting of a broadleaved forest (no expansion), a broadleaf–bamboo mixed forest (moderate expansion), and a pure moso bamboo forest (complete expansion). We measured soil P availability, physicochemical properties, extracellular enzyme activities, and plant stoichiometry. We found that compared to broadleaved trees, moso bamboo maintained comparable P levels in leaves and twigs but exhibited significantly lower P concentrations in roots and reduced available P in the rhizosphere. This indicates that moso bamboo possesses a highly efficient strategy for P uptake and internal translocation to support rapid growth. Importantly, ecoenzymatic stoichiometry in rhizosphere soil revealed that microbial P limitation in the rhizosphere intensified with the degree of expansion. These results indicate that the superior P acquisition strategy of bamboo depletes rhizosphere P, thereby exacerbating P limitation for soil microbes and potentially creating a competitive disadvantage for neighboring broadleaved species.
