Permafrost temperature profile. Permafrost occupies the middle zone, with the active layer above it, while geothermal activity keeps the lowest layer above freezing. The vertical 0 °C or 32 °F line denotes the average annual temperature that is crucial for the upper and lower limit of the permafrost zone, while the red lines represent seasonal temperature changes and seasonal temperature ...
Like humans, animals can be at risk of hypothermia if they become too cold. Veterinary charity PDSA advises giving dogs and cats extra blankets for their beds over the winter months and a few ...
Cryoturbation is the dominant force operating in the active layer, and tends to make it generally uniform in composition throughout. However, variation in the composition of soils due to differences in parent rock are very marked in permafrost regions due to the low rate of weathering in the very cold climate.
Dogor is a preserved canine specimen that was found in the Siberian permafrost of Sakha in 2018. It is a remarkably well preserved two-month-old male puppy with fur and whiskers remaining. The animal has been determined to be 18,000 years old. At first, DNA sequencing was unable to identify the

Not all questions have simple, yes or no answers—including this one. While many dogs are lactose intolerant, many are not! Lactose intolerance develops as a dog grows up, so it can be impossible ...
Drunken trees are not a completely new phenomenon—dendrochronological evidence can date thermokarst tilting back to at least the 19th century. [13] The southern extent of the subarctic permafrost reached a peak during the Little Ice Age of the 16th and 17th centuries, [24] and has been in decline since then.
Permafrost mummies provide crucial insights into the physiology and life histories of Pleistocene organisms, due to how well the preservation process keeps the specimens from decomposing. The constant presence of permafrost is able to preserve the soft tissues of organisms through a process similar to freeze-drying. [ 1 ]
