Ten reasons to love echidnas Natural History Museum
The discovery that echidnas hibernate, however, challenges this view because echidnas are monotremes, and monotremes are very old in evolutionary terms, having split from other mammals over 120 million years ago. Hibernation, thought the researchers, might be a much more ancient phenomenon than was previously thought..

The animal does not have brown fat, an energy reserve associated with hibernation in placental mammals. But the echidna does gain weight before beginning hibernation, just as more advanced mammals do.

Abstract. Short-beaked echidnas undergo both torpor and hibernation, expressed to different extents in different climates. We propose that when well fed animals hibernate in comparatively mild.
Facts About Echidnas Live Science
Echidnas hibernate during bushfires. These hedgehog-like animals in Australia often live in underground burrows or hollowed-out logs. They stay hidden away and wait out bushfires until it's safe to emerge and forage for food. What animal hibernates the longest? A dormouse can hibernate for up to 11 months in the wild, provided they've eaten.

Echidnas hibernate in some of these areas, but in their studies of hibernation and reproduction in Kosciuszko National Park (Beard, Grigg, & Augee, 1992), and south-east Queensland (Beard & Grigg, 2000), Beard and co-workers never found more than one male with a female, and also noted that no females re-entered hibernation after mating.

Short-beaked echidnas undergo both torpor and hibernation, expressed to different extents in different climates. We propose that when well fed animals hibernate in comparatively mild climates, with food available, they are using the winter cold as a resource and "putting themselves on ice" until the next breeding season.

Echidnas (Tachyglossus aculeatus) are amongst the largest deep hibernators, but it is difficult to get them to hibernate normally under laboratory conditions.We measured body temperature (T b)in 14 free-ranging echidnas using implanted data-loggers.Cooling during entry into hibernation bouts followed a Newtonian cooling curve, and conductances calculated from cooling curves were identical to.
Digging Echidnas are Essential Australian Ecosystem Engineers The Official PLOS Blog
Echidnas do not construct a complex hibernaculum, (although some mothers dig a nursery burrow after mating) and in our study area were found to hibernate in piles of bark, hollow logs, log windrows, refuges under rocks, and grass tussocks, or simply dug into the soil.
Echidna Fact Sheet Blog Nature PBS
Abstract. During hibernation there is a slowing of all metabolic processes, and thus it is normally considered to be incompatible with reproduction. In Tasmania the egg-laying mammal, the echidna ( Tachyglossus aculeatus) hibernates for several months before mating in mid-winter, and in previous studies we observed males with females that were.

The short-beaked echidna (Tachyglossus aculeatus, ∼3 kg; bottom-left),. Many hibernators fatten extensively before the hibernation season, do not hibernate when lean, and rely to a large extent on stored fat as an energy source in winter; some species use food caches or a combination of fat and caches.

Echidnas also hibernate in south-eastern Queensland and on Mt Kosciuszko at exactly the same time. So, rather than being entirely temperature driven, Stewart suspects hibernation is more to do with conserving energy over the period when ants and other invertebrate prey are in shortest supply. "We really don't know why they do it," he says.
