At the end of the summer they search for hibernation sites where they spend winter and spring. In contrast, the extent of chronic pathology, the removal of host blood during hibernation, is likely to be determined primarily by immune competence. At the protein level, myoglobin appears to increase in skeletal muscle as animals prepare for and undergo hibernation. Altogether 189 adults hatched and 36 larvae remained in hibernation. The beetles had recently emerged from winter hibernation and started to mate. It would be perhaps more justifiable to look for an intoxication as a cause of this phenomenon than as a cause of hibernation. In the early spring the arrival of migratory birds coincides with the ending of hibernation of the non-aedinine mosquitoes which fly around seeking blood. Like seeds in hibernation, they await a more receptive climate, in the meantime gathering strength and power. Peaks in activity levels are associated with migrations to and from hibernation sites and with breeding activity, especially mate searching by males. Some did certainly succumb to the new pressure and lost their fortunes, some went into hibernation anticipating that this uncongenial phase would soon be over. These larvae were either allowed to continue their development, or were cooled and subsequently put in the refrigerator for hibernation or shipment. Because the hibernating mammal arouses periodically from torpor throughout the hibernation season, the ability to function at euthermic temperatures must be maintained continuously. In broods kept under out-of-door conditions hibernation could be interrupted by several methods. The dust storm season problem can be accommodated by hibernation. The few genes that are 'switched on' during hibernation are mitochondrial genes, genes encoding antioxidant and stress proteins, and transcription factors. Thus, by the time the animals enter natural hibernation, large populations of uniformly sized hormone-responsive follicles exist in arrested meiosis within the ovary. In toads examined at the end of hibernation, fat reserves were negatively correlated with parasite intensity. Feeding continues throughout the summer until the adult weevils start preparing for hibernation. There are summaries of breeding behaviour, dietary requirements, hibernation, behaviour, and adaptation and evolution. During hibernation only 1-2% of the genes are turned on, protein synthesis is reduced to c. 1% and energy production to 5%. As described above the number of hibernating larvae increases gradually in the later summer generations, although the climatic conditions at this time of the year provide no cause for hibernation. A relatively small number of genes that perform crucial functions for hibernation will be up-regulated during winter, whereas other gene products that are not essential during hibernation may be down-regulated. The simultaneous occurrence of hibernation and of this inhibition of development by unfavourable conditions, or the interpretation of the latter as hibernation, have caused a number of rather puzzling statements. Altogether 105 imagines hatched and 30 larvae remained in hibernation, of which a number pupated and hatched without any change of conditions and the rest died.
