Summary: This study evaluated the thermal resistance of Acipenser baerii and its hybrids under chronic heat stress. The results showed that the hybrids exhibited higher survival rates and lower gill damage compared to A. baerii. Additionally, A. baerii was found to be more susceptible to heat stress, as indicated by increased levels of various stress markers in the early stages of exposure. These findings contribute to understanding the coping mechanisms of cold-water fishes to chronic heat stress.

Summary: Chaperone proteins, such as Hsp90, play a critical role in maintaining protein homeostasis in all living cells. Recent studies have shown that bacterial Hsp90 is essential for the survival of bacteria under stress conditions and is involved in the virulence of pathogenic bacteria. In this study, the researchers used site-directed mutagenesis to disrupt the binding between Hsp90 and the chaperone protein DnaK, and found that this collaboration is crucial for the folding of client proteins in bacteria. They also demonstrated that this collaboration between Hsp90 and DnaK in bacteria has evolved to form a more complex collaboration between Hsp70 and Hsp90 in eukaryotes.

Summary: Heat shock protein 70 (HSP70) is induced by cellular stresses and its expression in skeletal muscles has potential applications in ASCVD prevention. HSP70 can improve insulin resistance and chronic inflammation, two underlying pathologies of type 2 diabetes, obesity, and atherosclerosis. External stimuli like heat and exercise could enhance HSP70 expression, providing a possible alternative for ASCVD prevention in individuals who cannot exercise due to obesity or locomotive syndrome. Further research is needed to investigate the usefulness of monitoring serum HSP70 concentration for ASCVD prevention.

Summary: The study investigated the impact of heat stress on the expression of the HSP70 gene in chicken PBMCs. PBMCs were isolated from healthy adult birds and exposed to heat stress at 42 degrees C for 1 hour. The expression of HSP70 was gradually upregulated from 0 to 4 hours of recovery time, with peak expression observed at 4 hours. The study highlights the protective role of HSP70 against the deleterious effects of heat stress in chicken PBMCs and suggests the use of PBMCs as a cellular system for assessing heat stress in chickens ex vivo.

Summary: Heat stress induces functional and metabolic changes in cells and tissues, which can be assessed by histopathological alterations and biomarkers. Various pathomorphological changes and biomarkers associated with heat load have been observed in adaptive and productive organs of livestock. Immunohistochemical analysis identified biomarkers in growth-related organs, reproductive organs, and immune organs that could serve as reliable variables in heat stress assessment in livestock. Examining heat-stressed organ histopathology and identifying cellular markers by immunohistochemistry may help in screening climate-resilient livestock breeds and developing strategies to mitigate the detrimental consequences of heat stress to ensure sustainability in livestock production.

Summary: The study conducted a systematic identification and functional analysis of HSP70s in turbot, revealing their essential roles in adapting to various environmental stresses. The research identified 16 HSP70 genes distributed on nine chromosomes in turbot and provided valuable insights into their evolution, classification, and functional diversity. Expression analysis showed significant up- or downregulation of HSP70 genes under different stress conditions, with three genes (hspa1a, hspa1b, and hspa5) responding to all induced stresses, indicating their involvement in anti-stress mechanisms. These findings contribute to understanding the biological function of HSP70s in turbot and the development of stress-resistant strains in aquaculture.

Summary: Thermal performance curves are commonly used to study the effects of heat acclimation on animals, but may not accurately predict survival in the field. In intertidal mussels, cardiac thermal performance tests show changes in critical temperature and flatline temperature after heat acclimation, but further research is needed to understand their role in thermal acclimation.

Summary: European dairy cows are highly sensitive to heat stress, which significantly impacts their milk yield, welfare, and fertility. Heat shock proteins (HSPs) play a crucial role in mitigating the harmful effects of heat stress on the early embryo development. This study demonstrates that exogenous HSP70 can improve embryo yield and reduce the adverse effects of heat stress on embryo quality, suggesting a potential protective mechanism against heat insult.

Summary: Species with different life histories and communities tend to shift their phenology in response to climate warming, leading to increased phenological overlap and potential impacts on species interactions such as resource competition. Shifts in abundance distributions are not strongly influenced by species' seasonal timing or elevations, but phenological overlap increases in warmer years as species adjust their seasonal timing. Overall, grasshopper abundance is relatively robust to climate changes, but increased phenological overlap may decrease abundance by strengthening species interactions.

Summary: Organisms respond to climate variability and change through different mechanisms, particularly in terms of fecundity and survival. Understanding and predicting responses to climate change requires considering the differential effects of these two components, which vary systematically along climate gradients. Incorporating these differences into models can improve predictions of responses to recent climate change.

Summary: The study reveals that the mean embryonic acute heat tolerance decreases with decreasing latitude, and the developmental temperatures have different effects on heat tolerance at different latitudes. Based on the findings, it is projected that heat stress frequency will increase and shift towards lower latitudes with climate change, leading to habitat movements and reductions in southern regions.

Summary: Both mathematical models and biological model systems are tractable representations of complex biological systems or behaviors. While they facilitate research and provide insights, they may not be accurate as they omit details of the natural systems. To improve our inferences from models, further efforts in model development, improvement, and acceptance by the scientific community are advocated, along with a more explicit discussion of the purpose and power of models.

Summary: Squamate reptiles exhibit two reproductive modes: oviparity and viviparity. Existing large-scale studies suggest that viviparous species are more vulnerable to climate warming based on viviparous species occupying relatively colder environments, which are predicted to decline in availability under climate warming. However, oviparous and viviparous squamates are geographically widespread and their distributions often overlap. This study used Sceloporus lizards in North America as a model system and found that under climate warming, oviparous females are predicted to increase reproductive frequency more than viviparous females, which may lead to decreased maternal energy balance. Interestingly, the developmental success and offspring energy balance of oviparous species are predicted to decline at some sites under climate warming, while this is not predicted to happen for viviparous species. These findings highlight the variability in response to climate warming between oviparous and viviparous species, with oviparous species in hot areas with high temperature variation being especially vulnerable.

Summary: The sensitivity of insect populations to environmental conditions can impact their growth, development, and performance. High-elevation and season-limited populations exhibit developmental plasticity, enabling them to advance or prolong development in specific conditions, consistent with field phenology. This plasticity is driven by increased thermal sensitivity of development under short day conditions early in the season.

Summary: Understanding the thermal sensitivity of organisms is crucial for predicting the biological consequences of climate change. The commonly used approach of estimating thermal safety margins may not fully capture the performance of organisms at different body temperatures. This study finds that the asymmetry of thermal performance curves has important implications for thermal stress and performance decrement. Metrics that incorporate additional aspects of thermal performance curve shape provide a better measure of the thermal risk of climate change.

Summary: Organisms living in seasonal environments adjust their physiological and morphological characteristics in response to environmental shifts. Detecting these adjustments can be done by measuring organisms directly from nature or by rearing them in the laboratory under conditions that mimic natural ones. However, simulating natural conditions in the laboratory is challenging and requires knowledge of the natural history of the ecological environment.
