The air pollution tolerance index (APTI), anticipated performance index (API), and dust capturing capacity (DCC) of dominant urban street trees in Ranchi were studied at control, heavy traffic, and industrial sites during pre- and post-monsoon seasons. APTI varied significantly across seasons (F<sub>1,25.43</sub> = 27.24, p < 0.05), sites (F<sub>2,261.87</sub> = 280.50, p < 0.05), and trees (F<sub>9,9.18</sub> = 9.83, p < 0.05). APTI values were highest at industrial, followed by heavy traffic, and lowest at control sites. AA content was the most influential biochemical parameter associated with APTI, showing a statistically significant strong correlation (r = 0.819, <i>p</i> < 0.01). Street trees at industrial sites exhibited the highest APTI values (range: 15.11–19.99), followed by heavy traffic sites (12.79–18.30), and lowest at control sites (11.46–15.72). DCC also varied significantly across seasons (F<sub>1,0.321</sub> = 17.40, p < 0.05), sites (F<sub>2,2.65</sub> = 144.25, p < 0.05), and trees (F<sub>9,2.95</sub> = 160.92, p < 0.05). The highest DCC was recorded in <i>Melia azedarach</i> (2.64 mg cm<sup>−2</sup>), followed by <i>Bauhinia variegata</i> (2.49 mg cm<sup>−2</sup>), and <i>Bridelia retusa</i> (2.13 mg cm<sup>−2</sup>). APTI, API, and DCC were significantly affected by seasons, sites, species, and their interactions with pollutants. These findings highlight the importance of APTI, API, and DCC as important indicators of the pollution mitigation abilities of different urban street trees to recommend for urban greening initiatives in rapidly urbanizing cities like Ranchi.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":805,"journal":{"name":"Trees","volume":"39 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested this idea by sampling seven willow shrub (<i>Salix gyamdaensis</i>) sites spanning 4400–4800 m in southeast Tibet. A total of 171 ring-width samples were collected and measured. Detrended basal area increment (BAI) series were built for each site. The resulting BAI indices were correlated with NDVI and monthly climate variables. Shrub growth indices were positively associated with summer NDVI, suggesting the regional greening is associated with increased shrub growth. Willow growth also showed positive responses to summer temperatures at five out of the seven study sites. However, shrub growth in the other two sites showed either a positive response to the minimum temperature of the previous December or a negative response to August temperature.

Based on comprehensive tree census data (2010–2015) from a fully mapped 0.06-hectare permanent forest dynamics plot in the Da Xing’an Mountains, Northeast China, encompassing 32,565 individual trees, we classified forest stands into three distinct forest types according to species composition: mixed birch and larch forest, pure larch forest, and pure birch forest. A generalized linear mixed model was used to analyze the effects of the factors influencing the mortality of birch and larch in mixed and pure forests. Our research indicates that (1) competition is typically the primary cause of tree mortality. For the two main tree species, birch mortality shows greater sensitivity to increased conspecific competition, whereas larch mortality is more affected by higher hetero-specific competition. (2) For different stand types, species diversity had a more negative effect on the mortality of the two tree species in the mixed forest than in the pure forest. (3) Larch and birch mortality with varying tree diameter classes are found in different stands, and the significance of the factors influencing tree mortality patterns varies significantly. Our research demonstrated significant differences in the relative importance of variables driving tree mortality between pure and mixed forests and emphasized the role of both conspecific and hetero-specific competition in tree mortality.

To optimize large-scale restoration, it is essential to develop methods, such as direct seeding. Despite its ecological and socio-economic benefits, as well as its cost-effectiveness, direct seeding remains underutilized in Amazonian restoration initiatives. Thus, we evaluate the functional and taxonomic aspects of carbon recovery in 23 riparian forest permanent plots restored by direct seeding in southern Amazonia, approximately 12 years after restoration. We assessed aboveground carbon (AGC) stocks and four functional traits—specific leaf area (SLA), wood density (WD), seed size, and plant height—to analyse the effects of trait variation and species abundance on AGC stocks. We compared these parameters at the plot level between restored and primary forests, and at the species level between sown and naturally regenerating species. We found that restored forests after 12 years have AGC stocks 79% lower than regional primary forests. Five species account for up to 50% of the AGC, with sown species accumulating up to seven times more AGC than regenerated species. Restored forests showed a more acquisitive strategy, with higher SLA and lower WD than primary forests. Carbon stocks positively correlated with species abundance and functional trait variation. In conclusion, our results highlight that after 12 years, restored forests have not yet matched the AGC stocks or functional composition of primary forests, remaining dominated by a few species and functional groups. The dominance of AGC stocks by sown species underscores the effectiveness of direct seeding in facilitating revegetation and the positive relationships between carbon stocks and functional trait variation emphasize their importance as indicators of forest recovery.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":805,"journal":{"name":"Trees","volume":"39 4","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
