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

Physiological Systems in Insects discusses the roles of molecular biology,
neuroendocrinology, biochemistry, and genetics in our understanding of insects. All …

Water is of fundamental importance to living organisms, not only as a universal solvent to
maintain metabolic activity but also due to the effects the physical properties of water have …

Although higher temperatures strongly stimulate ectothermic metabolic rates, they only
slightly increase oxygen diffusion rates and decrease oxygen solubility. Consequently, we …

Insects exchange respiratory gases using an astonishing diversity of patterns. Of these,
discontinuous gas exchange cycles (DGCs) have received the most study, but there are …

Abstract SYNOPSIS. The Discontinuous Gas-exchange Cycle or DGC is generally thought to
have evolved primarily as a means of reducing respiratory water loss rates in tracheate …

For terrestrial animals and plants, a fundamental cost of living is water vapor lost to the
atmosphere during exchange of metabolic gases. Here, by bringing together previously …

The discontinuous gas-exchange cycles (DGCs) observed in many quiescent insects have
been a cause of debate for decades, but no consensus on their evolutionary origin or …

Do developmental constraints in ant colonies limit gas exchange strategies to those
displayed by female alates (presumptive queens)? In the xeric harvester ant genus Messor …

To assess energetic costs during rest and locomotion in a small insect, we measured
metabolic rate in freely moving ants Camponotus sp.(average body mass 11.9 mg). The …
