To what extent and in what way the distribution of steppe landscapes in the past and modern isolated steppe centers is associated with climate continentality has not been specifically studied yet. In this paper, the basins of the upper reaches of neighboring rivers, the Indigirka and Kolyma, are considered as a model. In the first basin steppe communities on the southern slopes of the valleys occupy an important place in the landscape, on a background of permafrost larch and Siberian dwarf pine communities. In the upper Kolyma River and further north, east and south, the area of steppe communities and diversity of steppe plants and invertebrates decreases sharply. A comparison of 28 characteristics of temperature regime, humidity and climate continentality indices revealed that the differences between the aforementioned regions are reliable and substantial only in winter. It cannot be excluded that the extensive distribution of steppe associations in the headwaters of the Indigirka is influenced by factors other than climate, such as the distinctive biogeochemical characteristics of the territory. The analysis of seasonal indicators of continentality may prove to be an important factor in the understanding of the climatic causes of past tundra-steppe dominance in the Northeast Asia.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":"1739-1751"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143962097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We collected 40 Pinus sylvestris cores from Bakuriani and extracted their blue-intensity (BI) signals, which capture latewood density closely linked to high-season temperature. After chemical treatment and high-resolution scanning, we employed correlation analyses to identify the seasonal temperature signal in BI. Then, we used a linear regression model-validated by local instrumental records from 1950-2020-to reconstruct April-September temperatures back to 1780 CE. Additional superposed epoch analysis tested the reconstruction's responsiveness to significant volcanic eruptions and solar variability. Our reconstruction strongly correlates with observed data (r = 0.72, p < 0.001), revealing significant warming trends alongside cooling events linked to volcanic aerosols and low solar activity in recent decades. Spatial analyses confirm that the BI-derived temperature variations align well with broader regional climate patterns. Furthermore, CMIP6-based projections under high-emission scenarios suggest possible warming of up to 8.75°C by 2100, highlighting the severity of future climate risks in the region. By integrating BI data, linear regression techniques, and superposed epoch analysis, this research demonstrates the effectiveness of tree-ring proxies in capturing both anthropogenic and natural drivers of climate variability.

The primary objective of this randomized controlled trial (RCT) was to investigate the effectiveness of a 3-week spa therapy intervention on the 6-month change in function (mobility and functional ability) of KOA patients. Secondary objectives examined the effectiveness of the intervention on KOA-related pain, stiffness, overall symptoms severity, and patient's quality of life. Community-dwelling adults, aged 50-80 years-old with KOA were randomized to spa therapy intervention or control (usual care) group. The primary outcome measure was assessed using the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) function subscale. Other outcome measures were the WOMAC pain subscale and a pain visual analog scale, the WOMAC stiffness subscale, the WOMAC total scores, the EQ-5D-3 L for quality-of-life, and patient reported outcomes. Among the 173 individuals randomized, 145 (n = 74 in spa therapy, mean age 67.5 ± 6.4, 67.6% women; n = 71 in controls, mean age 68.3 ± 6.7, 64.8% women) were analyzed. A significant between-group mean difference of 11.7 points in the WOMAC function subscale, favoring the spa therapy group, was found at six months follow-up (primary outcome measure). The intervention was effective in significantly improving most secondary outcomes, including the WOMAC stiffness, pain (and pain visual analog scale) and total scores, as well as the minimum clinically meaningful changes in KOA symptoms, and patient's quality of life.

To predict these events, it is important to investigate when and where DAPS prefer to occur and how they are related to other M-I phenomena. We conduct this investigation statistically using 10 years of Swarm data and find that DAPS under sunlit and dark ionospheric conditions exhibit different dependencies on magnetic local times and geomagnetic activities, reflecting a complicated interplay between magnetotail dynamics and ionospheric conductance. The statistical results also reveal a strong correlation between DAPS and embedded Region 2 currents.

Urban regeneration has been presented as a solution to those problems. This study investigates whether urban regeneration provides environmental benefits in terms of mitigating urban heat islands (UHI). Two large-scale urban regeneration areas in Ankara, the New Mamak Urban Regeneration Project (NMURP) and the North Ankara Urban Regeneration Project (NAURP), are anaylzed, both of which have been undergoing transformation more than a decade. Landsat 5 and Landsat 8 satellite images were used to detect the land use-based changes in the surface UHI, based on UHIER index, between 2005 and 2022, CORINE datasets were utilized for land use classification in the study areas for comparison. The results show that UHI values decreased in entire project areas due to removal of squatter settlements and partial completion of the transformation. However, when the local variations are observed, it is concluded that UHI values increased in already transformed sites as a result of high built-up densities, where complex cultivation pattern is replaced by urban fabric in NMURP, agriculture and construction sites replaced by urban fabric, natural grasslands replaced by road network and urban fabric, and urban fabric is replaced by urban green areas and construction sites in NAURP.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":"1517-1528"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12179009/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
