“…The metabolic rate tripled when the temperature increased from 10 to 20 • C and doubled when the temperature rose from 20 to 30 • C [56,57]. It has been shown that pupae of Musca domestica, with an increase in temperature from 5 to 41 • C, increase their emission of heat and CO 2 [49]. Similar correlations were observed in pupae of Cydia pomonella, where with the temperature increase, the heat emitted by pupae increased [58].…”

Climate change, and in particular the increase in temperature we are currently observing, can affect herbivorous insects. Aphids, as poikilothermic organisms, are directly exposed to temperature increases that influence their metabolism. Heat stress causes disturbances between the generations and the neutralization of reactive oxygen species (ROS). The aim of this work is focused on explaining how the aphid, using the example of Aphis pomi, responds to abiotic stress caused by temperature increase. The experiment was carried out under controlled conditions at three temperatures: 20, 25, and 28 °C. In the first stage, changes in the activity of enzymatic markers (superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), β-glucosidase, polyphenol oxidase (PPO), and peroxidase (POD)) were determined in aphid tissues, at each temperature. In the second stage, microcalorimetry monitored changes in heat emitted by aphids, at each temperature. Our results showed that A. pomi defense responses varied depending on temperature and were highest at 28 °C. The flexible activity of enzymes and increase in the metabolic rate played the role of adaptive mechanisms and ran more effectively at higher temperatures. The A. pomi thus protected itself against ROS excessive induction and the aphids were able to respond quickly to environmental stress.

“…The metabolism of living organisms can be measured as the rate of heat emission, CO 2 production, and O 2 consumption [49]. Our analyses showed that an increase in temperature from 20 to 25 and 28 • C caused an increase in the specific thermal power of aphids, most notably at 28 • C (Figure 4).…”

“…The effect of temperature on insect metabolism has been investigated in many species. Correlation between temperature and metabolic rate was shown previously in studies on pupae of Platynota stultana [25,26], Musca domestica [27], and Cydia pomonella [28]. Interestingly, the metabolic rate resulting from temperature changes may depend on species or geographical coverage.…”

Despite many studies of the aging process, questions about key factors ensuring longevity have not yet found clear answers. Temperature seems to be one of the most important factors regulating lifespan. However, the genetic background may also play a key role in determining longevity. The aim of this study was to investigate the relationship between the temperature, genetic background (fruit fly origin), and metabolic rate on lifespan. Experiments were performed with the use of the wild type Drosophila melanogaster fruit flies originating from Australia, Canada, and Benin and the reference OregonR strain. The metabolic rate of D. melanogaster was measured at 20 °C, 25 °C, and 28 °C in an isothermal calorimeter. We found a strong negative relationship between the total heat flow and longevity. A high metabolic rate leads to increased aging in males and females in all strains. Furthermore, our results showed that temperature has a significant effect on fecundity and body weight. We also showed the usefulness of the isothermal calorimetry method to study the effect of environmental stress conditions on the metabolic activity of insects. This may be particularly important for the forecasting of impact of global warming on metabolic activity and lifespan of various insects.

Calorimetric measurements on biological systems from small molecules to whole organisms lead to a new conception of the nature of live matter that has profound consequences for our understanding of biology. The data show that the differences in Gibbs energy (ΔG) and enthalpy (ΔH) are near zero or negative and the difference in entropy (ΔS) is near zero between a random mixture of molecules and live matter of the same composition. A constant input of energy is required to maintain ion gradients, ATP production, and the other functions of living matter, but because cells are organized in a spontaneous process, no energy input is required to maintain the structure or organization of cells. Thus, the origin of life and evolution of complex life forms occurs by thermodynamically spontaneous processes, carbon-based life should be common throughout the universe, and because there is no energy cost, evolution can occur relatively rapidly.However, observations on biological systems challenge Schrödinger's model. Despite the assumed formidable energy and entropy costs, life did originate at least once, and possibly more than once [2]. Second, energy from catabolism is not transferred into new tissue during growth; catabolic reactions are used in driving (i.e., increasing the rates of) anabolic reactions but do not contribute to an overall higher-energy state in the anabolic products [2,3]. Third, live matter exists in a state of suspended animation or in a state with an extremely low rate of respiration for extended lengths of time without energy input (e.g., see [4][5][6][7]), for example, microorganisms, resurrection plants, seeds, spores, estivating animals, bdelloids, and inhabitants of desert ephemeral pools. Fourth, experimental data show that life does not always feed on negentropy [8]. And, evolutionary changes occur with frequencies that are difficult to envision if change to more complex life forms requires formation of ever-lower-entropy, higher-energy, metastable states.Explication of the reaction defining the thermodynamic system in which live matter is formed from nonliving matter resolves the apparent inconsistencies between Schrödinger's model for live matter and these observations. Schrödinger [1] did not explicitly define the reaction used to conclude that the entropy of live matter is lower than that of the "foodstuffs" from which it was formed. The product is clearly living cells, tissues, or an organism, but the state of the live matter and what is meant by "foodstuffs", i.e., the reactants, are not clear. Is the live matter an animal in motion or is it an embryo in a seed in a state of suspended animation? In autotrophs, "foodstuffs" could mean CO 2 , H 2 O, and N 2 , or it could mean the substrates for respiration such as carbohydrates and amino acids. Whether living tissues are in a high-or a low-energy state is relative to the reactants and thus depends on the system considered.Comparison of a random mixture of molecules in aqueous solution and live matter of the same composition is the appropriate...
