Five early-flowering plant taxa were selected for analysis: Alnus (alder), Corylus (hazel), Populus (poplar), Ulmus (elm), and Salix (willow). Daily airborne pollen data were collected using a Hirst-type pollen trap in six cities across Poland, representing different climatic conditions. Firstly, long-term air temperature trends were analysed to identify spatial and temporal climate variability. Secondly, the differences in pollen seasons between stations were compared to assess the spatial variation. Thirdly, pre-season meteorological influences on season onset and intensity were analysed. Finally, the influence of meteorological parameters on daily pollen grain concentration in the atmosphere was examined. The results show that, in the second decade, the strongest temperature increases occurred in early-year months, potentially influencing early-flowering taxa. Over a 20-year period, the period with the highest pollen grain concentration starts earlier and lasts longer for most stations and taxa. Meteorological influences on pollen dynamics shifted over time, leading to spatial, temporal, and species-specific variation across Poland. Air temperature, insolation time, and relative humidity notably influence daily pollen levels, especially for Populus, Salix, and Ulmus (correlation > 0.2), while Corylus and Alnus show weaker correlations (< 0.1). The analysis indicates a decline in correlation coefficient values over the study period, particularly for Corylus and Alnus.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938242","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}

This study explores the temporal and spatial evolution of extreme climate events during the tobacco growing season in Southwest China and assesses associated climate disaster risks. By applying a range of extreme climate indices, spatial analysis techniques, and a climate disaster risk assessment model, the study identifies significant trends in future climate scenarios. The results indicate that indicators such as TN13 and TN20 exhibit a marked decreasing trend, while TX32, TXx, and TNn show upward trends, particularly in long-term projections. Extreme precipitation events demonstrate variability, yet an overall upward trend is evident. Spatial analysis reveals notable regional variations, with high-risk areas concentrated in the western, southern, and eastern regions, and low-risk zones in the central area. The climate disaster risk assessment indicates an expansion of medium to high-risk areas under future climate scenarios.

The study was conducted to evaluate the effects of heat and humidity stress on liver function markers and histological changes in rats fed a high fat diet, thereby enhancing our understanding of how environmental stressors impact liver health. A total of 180 albino rats (90 males and 90 females) were divided into 6 groups, with controlled environmental conditions, fed with their respective diets. Experimental rats were subjected to stress (4 h daily) in a temperature-humidity chamber for 30 days. Blood samples were collected at three intervals (each of 10 days) for biochemical analysis (ALT, AST, ALP, GGT, ALB, TP, and TB), and liver tissues were processed for histological examination. The study found significant alterations (P < 0.01) in liver enzyme levels, including elevated ALT, AST, ALP, and GGT in HFD-fed rats under heat and humidity stress compared to RD groups. However, TP, ALB, and TB showed non-significant variations (P > 0.05). Histological analysis revealed structural damage in the liver, including inflammation and necrosis, particularly pronounced in male rats. Gender-specific responses were observed, with males generally exhibiting higher (P < 0.01) enzyme levels and liver injury compared to females. Heat stress led to disrupted hepatic cords and hepatocyte ballooning in RD-fed rats, while HFD-fed rats exhibited central vein disruptions with minimal ballooning. Humidity stress caused vacuolization in RD-fed rats and frequent central vein disruptions in HFD-fed rats. The findings suggest that a high-fat diet exacerbates liver damage under heat and humidity stress, emphasizing the need for dietary considerations in managing stress-induced liver injuries.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938187","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 investigated lipid and fatty acids in the muscle and liver of the catfish Horabagrus brachysoma acclimated to 26 (control), 31, 33 and 36 °C for 30 days. The total lipid, phospholipid, triglyceride, and free fatty acid significantly decreased, while cholesterol significantly increased (P < 0.05) in both tissues at 33 and 36 °C. At 26 °C, total saturated fatty acids (SFA), particularly palmitic (C16) and stearic (C18) acids, accumulated in fish muscle and liver at levels 1.6 to 2.25 times higher than those in the feed (Tubifex worms). With increase in the acclimation temperatures, the SFA rose in muscle but reduced (P < 0.05) in liver, though both tissues still maintained nearly double the SFA content than in Tubifex. The muscle and liver unsaturated fatty acids (UFA) were 25% and 48% lower than in Tubifex at 26 °C, however, the muscle UFA decreased (P < 0.05) further with rising acclimation temperatures while liver UFA increased (P < 0.05) at 33 and 36 °C. Compared to the feed, oleic acid levels in the muscle and liver increased two- and threefold, respectively, with muscle content significantly peaking at 36 °C (P < 0.05). The ability of the catfish to deposit n-3 PUFA or to reduce n-6 PUFA to over twice the amount found in the feed (Tubifex) was disrupted at 33 °C, with muscle n-3 PUFA decreasing by 35% and n-6 PUFA by nearly 50% at 36 °C. A temperature-dependent decrease in DHA in muscle was also noted. Such reduction indicates decreased transfer of PUFA in the higher trophic levels and may also affect growth, development and disease resistance of the fish. Additionally, the content of oleic acid in catfish muscle nearly doubled compared to its feed at 26 °C, with levels increasing significantly with the rise in rearing temperatures (P < 0.05). It can be concluded that modulation of lipid and fatty acids is one of the ways by which H. brachysoma will attempt to acclimate to temperature rise due to global warming.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938097","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}

LULC patterns exhibit different driving mechanisms on land surface thermal environments across different seasons. However, so far, quantitative research distinguishing seasonal differences in LULC patterns at the landscape and class levels in relation to land surface temperature (LST) has remained limited. This paper applies the boosted regression trees (BRT) model and structural equation models (SEM) to investigate the seasonal variations in LST response to LULC patterns. The research findings indicated substantial seasonal variations in the response of LST to LULC. Pronounced cropland heat island effect was observed during spring and winter, whereas the heat island effect of built-up areas was pronounced during summer and autumn. The impacts of LULC indices on LST generally showed threshold effects, and clear interactions between different influencing factors were observed. An increase in core area percentage of landscape (CPLAND) or patch cohesion index (COHESION), when interacting with percentage of landscape (PLAND), notably enhanced LST variations. The impacts of landscape patterns across all LULC types on LST were pronounced and predominantly direct throughout all seasons. The variations in LST were dominated by the landscape patterns of built-up areas and forestland during summer and autumn, while the landscape patterns of cropland and forestland predominantly determined LST in spring, and the LST in winter was mainly influenced by the landscape patterns of cropland and water.

This could lead to a loss of physical work capacity (PWC loss) and result in significant economic risks. Here, we investigate the PWC loss risks and their recent changes under different heat stress environments for the period of 1985-2023. Changes in PWC loss risks on comfort days, defined by heat stress values of 20-29 °C, show a latitudinal contrast, with an overall decrease in low latitudes and an increase in high latitudes. However, they have increased everywhere on both discomfort days (30-45 °C) and dangerous days (above 45 °C), with a greater increase in the latter condition. This suggests that global warming is exacerbating the risks of PWC loss in more intense heat stress environments. Geographically, Western Europe, the Mediterranean, Siberia, the Caribbean, and northeastern South America have experienced more significant increases in PWC loss risks, exceeding 1.5 times relative to the climatological mean over the past four decades. Such changes are due more to changes in the frequency of heat stress days than to changes in the severity of PWC loss.
