... is more akin to quiescence (see Glossary), an arrest that lacks the photoperiodic-programming aspect that is characteristic of most other insect dormancies ( Lirakis et al., 2018 ). That being said, we can still learn much from the dormancy of D. melanogaster , which, at the molecular level, shares many...

...Giulia S. Rossi; Patricia A. Wright ABSTRACT Several animals enter a state of dormancy to survive harsh environmental conditions. During dormancy, metabolic depression can be critical for economizing on limited endogenous energy reserves. We used two isogenic strains (strain 1 and strain 2...

...Giulia S. Rossi; Rebecca L. Cramp; Patricia A. Wright; Craig E. Franklin ABSTRACT Many animals occupy microhabitats during dormancy where they may encounter hypoxic conditions (e.g. subterranean burrows). We used the green-striped burrowing frog ( Cyclorana alboguttata ) to test the hypothesis...

..., a state of dormancy characterized by exceptionally low metabolism and high stress tolerance. Synthesis of molecular chaperones such as the J-domain proteins ArHsp40 and ArHsp40-2 occurs during embryo development and post-diapause growth of A. franciscana and they influence development and stress tolerance...

During dormancy, plasma glucose levels are 60% lower than those in active animals, while total protein, total lipids and β-hydroxybutyrate...

... of the atrophic response during extended periods of inactivity, both artificially imposed (e.g. limb immobilisation) and naturally occurring, such as the quiescence associated with dormancy (e.g. hibernation and aestivation). The severity of muscle atrophy is positively correlated with mass-specific metabolic...

...-ventilatory periods lasting 1.8–26 min. Dormancy at the higher body temperature was accompanied by higher rates of O 2 consumption and ventilation. The increase in ventilation was due only to increases in breathing frequency with no change observed in tidal volume. The air convection requirement for O 2 did...

... dormancy has been linked to the inhibition of protein synthesis in quiescent embryos. In this study, we have addressed the level of control at which a mechanism mediated by intracellular pH might operate to arrest protein synthesis. Two independent lines of evidence suggest that there is an element...

We tested the effects of ambient hypercapnia and hypoxia on oxygen consumption and on extracellular...

Cycles of CO 2 retention and release might be the result and/or the cause of changes in metabolic rate during dormancy. Ventilation is sensitive primarily to O 2 , and O 2 transport appears to be diffusion...
