Alaskozetes antarcticus is a species of non-parasitic mite, known for its ability to survive in subzero temperatures. [1]This animal's name derives from its habitat: Alasko, meaning "from Alaska", and antarcticus, in connection with frigid conditions in which the mite lives.
Mites of domestic animals cause important types of skin disease, and some mites infest other organs. Diagnosis of mite infestations can be difficult because of the small size of most mites, but understanding how mites are adapted to feed within the structure of the skin is useful.
Freeze-avoidant insects cannot tolerate internal ice formation, so they avoid freezing by depressing the temperature at which their body fluids freeze. This is done through supercooling, the process by which a liquid cools below its freezing point without changing phase into a solid. In order for water to freeze, a nucleus must be present upon ...
They inhabit organic debris of all kinds and are extremely numerous in leaf litter. They feed on animals, plants and fungi and some are parasites of plants and animals. [37] Some 48,200 species of mites have been described, [38] but there may be a million or more species as yet undescribed. [16]
A hibernaculum (plural form: hibernacula) (Latin, "tent for winter quarters") is a place in which an animal seeks refuge, such as a bear using a cave to overwinter.The word can be used to describe a variety of shelters used by many kinds of animals, including insects, toads, lizards, snakes, bats, rodents, and primates of various species.
Heat shock proteins also help the tolerance to both high and low temperatures. [8] Belgica antarctica not only tolerates, but also requires a freezing climate to survive: exposure of larvae to such mild temperatures as 10 °C is enough to kill them within a week. [7] Exposure to temperatures of 30 °C kills individuals in a few hours. [8]
Another popular orchid, Cattleyas, will do well with a range of 50 to 80 percent humidity." If your orchid needs a humidity boost, putting a cloche over it or a water tray under the pot can help.
Freezing of the head and thorax in other insects tends to have adverse effects on neural tissue, so it is not surprising that these protective mechanisms have been observed in certain species, but E. nugatoria is the only insect known to semi-freeze through the winter. By allowing the abdomen to freeze, evaporative water loss is reduced over ...
