Ainu hunters caught hibernating bears or bears that had just left hibernation dens. Many animals other than humans often induce hypothermia during hibernation or torpor. Still, many ectothermic animals undergo periods of dormancy which are sometimes confused with hibernation. Germination involves the dormant endospore starting metabolic activity and thus breaking hibernation. Botanists can use the term "seed hibernation" to refer to a form of seed dormancy. Instantaneous resumption is one of the advantages of sleep mode over hibernation. Bearded dragons go through a type of hibernation called brumation. They rely on their fat reserves during their long winter hibernation. In the den, she enters a dormant state similar to hibernation. Marmots breed soon after emergence from hibernation. Their circadian rhythm stays intact during hibernation. Temperate bat species may swarm at hibernation sites as autumn approaches. Grizzly bears do not defecate or urinate throughout the entire hibernation period. Hunting disrupts migration and hibernation patterns and destroys families. It is possible to disable hibernation and delete codice 2.
