Employing the clear, student-friendly style that made previous editions so popular, Insect
Physiology and Biochemistry, Fourth Edition presents an engaging and authoritative guide …

The regulation of body temperature (thermoregulation) and of water balance (defined here
as hydroregulation) are key processes underlying ecological and evolutionary responses to …

Air sacs are a well-known aspect of insect tracheal systems, but have received little research
attention. In this Commentary, we suggest that the study of the distribution and function of air …

Insect cold tolerance depends on their ability to withstand or repair perturbations in cellular
homeostasis caused by low temperature stress. Decreased oxygen availability (hypoxia) …

Insects exchange respiratory gases with their environment through their gas-filled tracheal
system, a branched tracheal tree extending from segmental openings and terminating at fine …

The study of desiccation resistance and its underlying traits is key to understanding species
responses to changes in water availability, especially in the context of predicted increases in …

The tight association between ambient temperature (T) and metabolic rate (MR) is a
common occurrence in ectotherms, but the determinants of this association are not fully …

Understanding the physiological tolerances of ectotherms, such as thermal limits, is
important in predicting biotic responses to climate change. However, it is even more …

The origin of the allometric relationship between standard metabolic rate (MR) and body
mass (M), often described as MR= aMb, remains puzzling, and interpretation of the mass …

We examined the effects of humidity on the metabolic rates and respiratory patterns of
Gromphadorhina portentosa (Schaum)(Blattodea: Blaberidae) to determine whether insects …
