This study explores the thermal performance and energy demands of a six-story office building in Osaka, Japan, under current (2020s) and projected (2090s) climate conditions. Although extensive studies have explored building energy performance and climate resilience, limited research has focused specifically on hot and humid climates, where extreme temperature and moisture levels significantly impact building behavior. EnergyPlus is used to simulate indoor air temperature, operative temperature, Predicted Mean Vote (PMV) for thermal comfort, and the energy consumption of a Variable Refrigerant Flow (VRF) heat pump system. Results indicate significant overheating in unconditioned zones, with operative temperatures exceeding 36 °C during summer in the 2090s. Conditioned zones also experience challenges, with cooling set-points surpassed on extremely hot days. Energy consumption analysis reveals a 20 % increase in cooling demand, from 3323 kW in the 2020s to 3983 kW in the 2090s, highlighting the impact of climate change. The findings emphasize that passive cooling strategies, such as cross-ventilation, dynamic shading, and high-performance insulation, can reduce cooling loads by 15–25 %. These results underscore the urgent need for climate-resilient building design and provide actionable insights for adaptive strategies in hot-humid urban environments. Future work will integrate adaptive comfort models and explore hybrid passive-active systems to enhance resilience. Future research will integrate adaptive comfort models and investigate hybrid passive-active systems to further enhance building resilience under extreme climate conditions.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"131 ","pages":"Article 104212"},"PeriodicalIF":2.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144653719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamics of STO during local heating are determined by both SkBF and the diverse mechanisms of heat transfer within biological tissues. The aim of this study is to investigate the changes in the phase and amplitude of STO resulting from local heating. The skin temperature was measured on the palm surface of the distal phalanges of the left hand fingers (index IF, middle MF and ring RF). The research involved a group of 10 healthy participants. Before heating, the STO amplitudes for IF, MF, and RF have almost equal values and oscillations are highly correlated. During heating, the IF amplitude decreases in the intermediate stage but recovers eventually. The IF signal has also undergone phase inversion such that the correlation with other fingers becomes negative. Meanwhile MF-RF correlation remains high throughout the measurement. A mathematical model founded on the heat transfer equation, wherein SkBF oscillations are represented by time-dependent perfusion, reveals that the amplitude and phase of STO are determined by the mean tissue temperature. The relationship between the STO amplitude and phase and tissue temperature during local heating is shaped by both microvascular vasodilation and the thermal boundary conditions. This study introduces a novel approach by combining phase and amplitude analysis of STO and highlights the intricate interplay between microvascular function and thermal dynamics, offering potential advancements in the design of diagnostic tools for assessing vascular health.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"131 ","pages":"Article 104200"},"PeriodicalIF":2.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although fecundity and viability of egg masses were mostly unaffected by exposure to 35 °C, even a one-month exposure to 35 °C doubles the age at which females produce viable egg masses, hence increasing generation time and reducing population growth rate.

Tadpoles exposed to HW developed faster than those exposed to HW as embryos, or to controls. Toadlets that were exposed to HW as embryos showed higher activity of the antioxidant enzyme superoxide dismutase than controls, but only toadlets exposed to HW as tadpoles showed higher concentration of thiols, indicating upregulated endogenous antioxidant defenses. Furthermore, toadlets exposed to HW during the larval stage spent more time climbing the open-field arena walls suggesting higher dispersal tendency. Overall, our results indicate stronger physiological and behavioural carry-over effects on toadlets exposed to HW as larvae, compared to those exposed to HW as embryos.

We examined the hibernation pattern of a wild hedgehog population (<em>Erinaceus europaeus)</em> in a semi-rural habitat in the north-west of England that is subject to a mild winter climate. We conducted night surveys across a 1-year study period, collecting population-level activity data on a total of 26 individuals as well as detailed data on hibernation timing and pattern in five individuals tagged with temperature-sensitive VHF tags through the hibernation period. While all five tagged individuals employed hibernation, we found a variation of up to 93 days in the hibernation start date and 47 days in end date between individuals, although the general pattern of hibernation such as average torpor bout duration was similar. Some individuals used shorter torpor bouts over an extended period in combination with extended activity of several days prior to the onset and after termination of hibernation, presumable allowing them to save energy during the colder nights while being able to forage during warmer days when invertebrates were active.
