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.

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.

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.

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 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.
