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.

Various rehabilitation approaches, natural healing factors, and curative agents are commonly used for osteoarthritis management. A key question remains whether treatments involving mud and mineral water therapies in resort-based sanatoriums are more effective than conventional rehabilitation procedures. To address this, we analyzed clinical trials since 2000 that compared the effects of balneotherapy and peloid therapy, either alone or in combination, with standard rehabilitative thermal interventions in managing peripheral joint osteoarthritis. A systematic review of 40 controlled trials from PubMed, Cochrane Library, PEDro, and Web of Science evaluated the effects of these therapies on osteoarthritis patients. The inclusion criteria were guided by the PICO model, focusing on various mineral water and mud therapies versus routine rehabilitation. All assessed outcomes were included in the intergroup analysis. Most studies focused on knee osteoarthritis, with 62.7% of participants being female. Significant intergroup differences were found in improvements in pain, stiffness, and physical performance, with better long-term outcomes observed in patients receiving mineral water or mud therapy compared to controls.

Common strategies to mitigate UHI include expanding water areas and green spaces, designing effective ventilation systems, and promoting energy-efficient buildings. In addition, shade structures have become a widely used thermal adaptation measure in outdoor environments. In this study, we investigated the walking speed and thermal comfort of pedestrians during the transition from outdoor to air-conditioned indoor spaces and categorized the influencing factors into three main dimensions: physical environment, physiological dimension, and psychological response. The analysis was conducted by means of a scale survey and observation. The results of the study present several key points. First, shading in outdoor environments slowed down walking speed by 4% in summer, with a decrease in walking speed of 1.1 m/s for every 1 °C decrease in Tmrt (mean radiation temperature). Second, men generally walked faster than women under different shading conditions. At the 95% confidence level, T-tests showed that shading had a significant effect on both genders (p < 0.05), with a more pronounced difference in walking speed for males. Finally, the Thermal Comfort Vote (TCV) remained in the neutral to satisfactory range when walking in shaded outdoor areas. In addition, switching to an air-conditioned space after staying in a shaded outdoor area increased comfort. In contrast, to achieve a similar level of comfort indoors after a stay in an unshaded area, the air conditioner needed to be set at a temperature 0.75 °C lower than the original temperature. These results emphasize the important role of shading in improving thermal comfort and its potential to reduce building energy consumption.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955484","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}

The objective of this study was to evaluate the influence of shading levels (SL) and climatic seasonality on the morphophysiology of young Myrcianthes pungens (O. Berg) D. Legrand and Cupania vernalis Cambess plants in a subtropical region. Species of significant importance for restoration were subjected to four levels of shading (SL0, SL18, SL50, and SL70) and evaluated during contrasting seasons of temperature and growth (winter and spring). In winter, both showed an increase in specific leaf area and variation in the amount of chlorophyll a and b, mainly under SL50 and SL70, which optimized photosynthesis under reduced light, sunlight hours and solar radiation. The increase in radiation and air temperature in spring denoted greater maximum assimilation of CO₂ in plants under SL18, SL50 and SL70, which from the analysis of principal components can be justified by the characteristics of the microclimate generated in these environments. Therefore, to optimize growth, M. pungens and C. vernalis must be planted under 50% shading because of morphophysiological adaptations in plants during seasons with subtropical climatic characteristics.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958199","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}

Field measurements were conducted in the most common street morphologies and compared with data obtained from meteorological stations (MS). Subsequently, the influence of tree presence were evaluated for the measured streets, and PET assessments were conducted by incorporating fisheye photographs of the most common tree species in the region into the SVF calculations. The results indicate that EW-oriented streets, particularly the Left Lateral, experience beyond extreme heat stress due to extended sun exposure. PET results from MS were inconsistent with local conditions. The analysis of Platanus orientalis, Populus canadensis, and Robinia pseudoacacia on PET in different street orientations showed reductions of 5-6 °C, particularly for the first two species during morning and midday. This equates to a PET reduction from Beyond extreme heat stress (I) to Extreme heat stress, for heat stress beyond 41 °C. Although this reduction is significant, tree shade had limited impact under such extreme heat. The study found that trees on the left side were more effective when placed on one side, while the right side provided stronger cooling when trees were on both sides in both E-W and N-S streets.

The aim of this research was to evaluate the mortality risk associated with cardiovascular diseases (CVD) due to suboptimal temperatures (daily mean temperature) and temperature variations (diurnal temperature range). Daily data spanning from 2014 to 2020 in Wuhu City were gathered, encompassing meteorological factors, environmental pollutants, and cardiovascular disease mortality information, involving 64,758 CVD deaths. Time-series analyses were conducted utilizing generalized additive models (GAM) and distributed lag nonlinear models (DLNM). Burden analysis was executed to estimate the percentage and count of daily CVD deaths linked to daily mean temperature (DMT) and diurnal temperature range (DTR). Lastly, a sensitivity analysis was conducted to assess the robustness of the model. A horizontal S-shaped relationship exists between DMT and CVD mortality rate, where both high and low temperatures exhibit adverse effects, with high temperatures demonstrating a more pronounced impact than low temperatures. An inverted J-shaped relationship exists between DTR and mortality, wherein extreme DTR elevates the risk of CVD mortality. Variations in exposure responses occur among populations with diverse characteristics. The main cause of death burden is moderately high temperature rather than extreme temperature.

Concurrently, six distinct ML models were evaluated and optimized using Bayesian optimization (BO) technique, considering performance indicators like weighted accuracy, F1-Score, precision, and recall. Notable trends emerged, with the CatBoost Classifier demonstrating superior performance in UTCI prediction, the Random Forest classifier excelling in PET estimation, and the XGBoost Classifier achieving optimal PMV prediction. Furthermore, the study delved into the influence of morphological features on OTC, prioritizing factors using SHAP values. Results consistently identified 90-degree orientation, street width, and 180-degree orientation as pivotal factors influencing OTC, with varying degrees of sensitivity across different classifications of thermal stress. Analysis of binary SHAP values unveiled intricate relationships between urban features and OTC indices, emphasizing the critical influence of street orientation on regulating outdoor thermal environments for UTCI and PET scenarios.

These models improve on simple phenological expectations by harnessing the intricate relationship between bird movements and weather conditions to forecast migration fluxes days in advance. However, state-of-the-art models face limitations as bird fluxes are often simply modelled as a response to local and instantaneous weather without accounting for previous and synoptic weather patterns. This study focuses on enhancing bird migration forecasts by evaluating the contributions of weather dynamics at various spatial and temporal scales. We use bird vertical density data from 9 French weather radars over 6 years and employ gradient-boosted regression trees for predictions. Dimension reduction tools are used to describe local and continental-scale weather conditions from the previous three days. We also explore the contributions of the different meteorological metrics considered using explainable regression trees tools. Our model improved phenology models by explaining about 1.3 and 2.25 times more additional variance than approaches based on local and instantaneous weather conditions in spring and autumn, respectively. Local and instantaneous weather metrics contributed the most, but they mainly helped identifying nights with low migration. In contrast, weather metrics for previous 3 days were crucial to forecast highest intensity migration events, as they enabled to account for bird accumulation in relation to unfavorable weather locally and remotely. This study enhanced forecast accuracy and contributed to a deeper understanding of the factors influencing bird migration. It enabled the identification local and synoptic weather patterns related to important migration events without a priori knowledge. It is therefore easy to interpret, easy to transfer to other ecological systems, and promising for the accurate forecast of migration peaks. Forecasted peaks can guide conservation efforts, for example by dimming lights for birds at night or by shutting down wind turbines.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143952771","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}
