Summary: This article examines the rate at which reversible phenotypic plasticity (RPP) occurs and its potential impact on how organisms overcome environmental challenges. The study suggests that current theoretical models do not consider the evolutionary potential of RPP rates. If the rate of plasticity itself can evolve, it may alter the organism's perception of environmental predictability and influence the slope of the evolved reaction norm. The optimization of phenotypic plasticity rates, their evolutionary dynamics in different environments, and the costs associated with them warrant further exploration in future research.

Summary: This study further characterized the 3A4-BMR chimera using differential scanning calorimetry and evaluated the stabilizing role of BMR. The fusion to BMR was found to have a significant effect on thermal stability but a minimal effect on catalytic activity. Different linker loop lengths had an impact on both activity and stability of the chimera, highlighting the importance of careful design and evaluation of P450-BMR chimeras.

Summary: Mechanical stimulation has great potential to control the growth of plants, resulting in more compact and stable plants. In this study, tomato plants exposed to air stream stimulation showed reduced leaf area and increased radial growth, leading to a more compact phenotype. The air stream-treated plants were able to maintain biomass accumulation by adjusting resource allocation.

Summary: Thermal tolerance plasticity is important for organisms to cope with climate change, and understanding its variation is crucial. The baseline tolerance/plasticity trade-off hypothesis (TOH) suggests that organisms with high baseline thermal tolerance have reduced plasticity. While many studies support the TOH, caution is needed as common testing methods can yield false trade-offs due to regression to the mean. Reanalyzing 25 previous analyses, it was found that only six remained significant after adjusting for regression to the mean, indicating an overestimation of TOH support.

Summary: Contrary to expectations, tropical and temperate coral species exhibited similar performance breadths in photosynthesis and electron transport rates, with thermal optima generally below local average temperature. This suggests that corals have adapted to cope with temperature variation, but current temperatures are pushing the boundaries of coral thermal tolerance.

Summary: An individual's fitness cost associated with environmental change depends on the rate of adaptive phenotypic plasticity. However, understanding of plasticity rates in an ecological and evolutionary context remains limited. A quantitative synthesis of existing plasticity rate data reveals considerable variation in plasticity rates among species, with different rates observed among higher taxa.

Summary: Animal species, including humans, exhibit individual variability in cognition that is difficult to explain. This study demonstrates that cognitive plasticity contributes to this variability. The results show that guppies exposed to different levels of resource predictability develop different cognitive abilities, suggesting that adaptive cognitive plasticity is a key determinant of cognitive individual differences.

Summary: This study examines the phenotypic plasticity in response to environmental change, focusing particularly on gradual phenotype changes and their ecological consequences. Experimental results suggest the importance of gradual plasticity in certain environmental contexts, and the developed mathematical model shows better explanatory power for population dynamics in variable environments. Understanding and considering the ecological effects of plasticity in variable environments are crucial for making accurate predictions and advancing ecology.

Summary: The study found that although the relationship between basal tolerance and plasticity was not significant in non-acclimated flies, there was still a strong correlation between the two in cold-acclimated flies, which may be influenced by statistical artifact. This suggests that previous patterns of thermal tolerance trade-off in similar studies may be affected by regression to the mean effects. Control and correction for such effects are crucial in determining the existence of a trade-off or physiological constraint.

Summary: With the ongoing climate change, the thermal biology of large yellow croaker, an important mariculture fish in China, was evaluated. The study found that large yellow croaker has a certain thermal tolerance to cope with high sea surface temperatures caused by climate change, but long-term exposure to high temperatures may result in reduced growth and increased oxidative stress. Therefore, the current farming mode of large yellow croaker may be more vulnerable to elevated temperatures on production.

Summary: Reversible phenotypic flexibility allows organisms to adjust to environmental conditions, and the costs and constraints of this flexibility are not well understood. This study found that high basal metabolic rate (BMR) is positively correlated with flexibility in BMR, but flexibility in maximum cold-induced metabolic rate (M-sum) or metabolic scope does not generally incur elevated costs.

Summary: This study found that cold-affiliated species in Andean tropical montane forests struggle to adapt their leaf functional traits to warming, while warm-affiliated species are able to adjust their traits from acquisitive to conservative strategies in response to cooling. This suggests that warm-affiliated species may have a competitive advantage under climate change, potentially leading to compositional shifts in these ecosystems.

Summary: The Climate Variability Hypothesis (CVH) predicts that ectotherms from thermally variable climates should have wider thermal tolerances than their counterparts living in stable climates. We tested this hypothesis by measuring CTMIN, CTMAX, and thermal breadths of aquatic mayfly and stonefly nymphs from adjacent streams with distinctly different levels of thermal variation. In support of the CVH, we found that mayfly and stonefly nymphs from the thermally variable stream had broader thermal tolerances than those from the thermally stable stream. However, the underlying mechanisms for these differences differed between species, with mayflies relying on long-term strategies and stoneflies using short-term plasticity.

Summary: Vector-borne diseases are vulnerable to climate change and the Chagas disease is transmitted by Triatoma infestans, one of the main vectors. Research found that the thermal performance of T. infestans is influenced by temperature acclimation and body mass, as well as the non-linear effect of thermal variability on their performance.

Summary: Most food web models fail to consider the complexity of interactions involving microbes in a community. This study evaluated the role of carcasses as multidimensional resources and explored sex-based dietary partitioning in Andean condors. The findings suggest that carcasses represent a trophic heterogeneous resource, and vertebrate scavengers can consume different trophic groups within the carcass, from autotrophs to secondary consumers.

Summary: Estimating energy expenditure is crucial for addressing ecological issues and conservation strategies. This study validates a movement model estimation of puma energy expenditure using doubly labeled water. The results show that this estimation method is consistent with other approaches, and that decreasing air temperature and increasing movement distance are correlated with higher energy expenditure in monitored pumas.

Summary: Social isolation has a significant impact on health, leading to various physiological disorders and even increasing the risk of early-onset neurodegenerative conditions. The effects of social isolation differ between genders, with males being more susceptible to inflammatory states and females more susceptible to oxidative states. Long-term social isolation results in the accumulation of tau and Aβ proteins, increasing the susceptibility to early-onset neurodegenerative conditions.

Summary: Social interaction has positive effects on animal performance by preventing stress-related events, providing security, and enhancing reproductive output and survival. This study investigates the effects of prolonged chronic social isolation stress on behavioral, cognitive, and physiological performance in the long-lived rodent Octodon degus. The results demonstrate that social stress increases anxiety-like behaviors and reduces social and working memory in male degus. Moreover, social stress decreases the multifractal complexity of basal metabolic rate, indicating a decreased ability to respond to environmental stressors and an unhealthy state. This study integrates cognitive-behavioral performance and multifractal dynamics of physiological signals in response to prolonged social isolation, highlighting the importance of social interactions for the well-being and overall performance of social animals.

Summary: The environmental conditions experienced by developing animals affect the development and maturity of the immune system. Specifically, the diet during early development impacts the maintenance and function of the immune system. Exposure to low-protein diets during early development has been linked to a reduction in immune competence in adulthood, but further research is needed to understand how nutritional history modulates immune function in different types of animals.
