However, climate change will impact species physiological traits, behaviour, reproduction, and phenology before their critical thermal limits are reached. Thermal performance curves (TPCs) are one way to evaluate how temperature impacts ecologically relevant traits before species reach their upper thermal limits. Comparing species TPCs to the climatic conditions they experience through their geographic ranges can provide insights into how vulnerable species are to further climate change and how their ranges might be altered. We assessed how flight performance – an important trait for escaping predators, dispersing, and finding resources and mates – is affected by temperature in two agriculturally important species of native stingless bees, <em>Austroplebeia australis</em> and <em>Tetragonula carbonaria</em>. <em>A. australis</em> has a broad arid/tropical geographic range and <em>T. carbonaria</em> has a narrower coastal subtropical range. We tested the thermal flight performance of both species at seven distinct temperatures between 18 and 42 °C. <em>A. australis</em> had a broader TPC and higher thermal optima than <em>T. carbonaria</em> reflecting the broader range of environmental temperatures and the hotter average environmental conditions they experience across their range. However, while <em>A. australis</em> could maintain flight performance at hotter temperatures, a larger proportion of their range is hotter than their thermal optima, suggesting their geographic range might constrict prior to the range of <em>T. carbonaria</em>.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"133 ","pages":"Article 104286"},"PeriodicalIF":2.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145301726","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}

Research on the effects of temperature on brain mechanics is limited, and studies relevant to surgical conditions have largely focused on reporting empirical results without further mechanical interpretation. To our knowledge, a comprehensive, model-based analysis of thermal effects on the mechanical response of brain tissue under conditions resembling surgery is still lacking. This study aims to fill the long-standing gap by quantifying undercharacterized thermo-frequency–dependent aspects of brain tissue and providing temperature-sensitive, model-ready properties for surgical conditions. To this end, oscillatory shear tests were performed on bovine brain tissue at 1 % strain across a frequency range of 0.1–100 rad/s and at three temperatures: 5 °C, representing hypothermic preservation, and 25 °C and 35 °C, approximating the room and physiological temperature range, respectively. A Generalized Maxwell model was fitted to present viscoelastic parameters. Across most frequencies, experimental results showed that storage (G′) and loss (G″) moduli decreased with increasing temperature, with 5 °C values significantly higher than those at higher temperatures, which were not significantly different. Fits to the model quantitatively parameterized the softening trend, showing a decrease in stiffness parameters with increasing temperature. Additionally, the model showed that the rise from hypothermic to room or physiological temperature reduced the viscous contribution and increased the elastic contribution, thereby altering the tissue's stress-relaxation behavior.

Fourteen participants were randomly exposed to Exer-H (ergocycle at 60 % VO_2max at 30 °C) and Exo-H (hot-water immersion up to the waist, 43–44 °C). The heating phase ended when T_rec (Peak) reached 39 °C, or was &lt;39 °C but reached the volunteers’ limit point of tolerance. The post-heating phase (passive sitting) ended when T_rec decreased to 37.5 °C. Blood prolactin concentration and T_sk were assessed during the heating and post-heating phases, and thermal perceptions were determined during the heating phase. Peak T_rec was slightly higher in Exo-H than Exer-H (39.00 ± 0.00 °C vs. 38.82 ± 0.27 °C; P = 0.028). The Δ changes in prolactin concentration and T_sk (especially Calf and Thigh) were larger in Exo-H during the heating and post-heating phases (P &lt; 0.05). Sweating/shivering, thermal comfort, and thermal sensation scores did not differ between Exer-H and Exo-H during heating. Positive relationships were found between Δ changes in prolactin concentration and Δ changes in T_sk, with the best associations observed for T_sk Calf and T_sk Thigh in both phases. Thermal comfort/sensation correlated positively with Δ changes in prolactin concentration, while sweating/shivering correlated negatively with body mass loss (%). In conclusion, prolactin concentrations show a more pronounced increase during Exo-H compared to Exer-H, despite a closely matched elevation of T_rec. This result may be explained by the large differences in T_sk of the lower limbs between the two heating conditions. Moreover, thermal perceptions are not differently affected during Exer-H and Exo-H. Our findings suggest that sweating sensation could partially reflect the hydration status, while thermal comfort and sensation may be partly connected to changes in prolactin concentrations.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"133 ","pages":"Article 104290"},"PeriodicalIF":2.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145268782","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}

It offers real-time, repeatable results, making it useful for monitoring and guiding timely interventions. This cross-sectional study was conducted on 56 participants diagnosed with knee osteoarthritis to evaluate the role of infrared thermal imaging in assessment and immediate monitoring. Thermal imaging measurements were obtained from both affected and contralateral knees using standardized protocols.

Therefore, we aimed to investigate the role of microhabitat use in two high-mountain lizard species (<em>Abronia</em> genus) with different habitat preferences (terrestrial and arboreal) on the degree of coadaptation between thermal physiological parameters and thermoregulatory strategies. We found that environmental pressures, driven by habitat use and seasonality, result in differential responses in both behavioral thermoregulation strategies and the physiology of these species. This high response capacity has allowed them to compensate for thermal fluctuations in their microhabitats and has, to some extent, promoted the coadaptation of selected temperature (<em>T_sel</em>), thermal optimum (<em>T_o</em>), and thermal performance breadth (B₈₅), along with thermal limits and thermoregulatory strategies.
