Mechanism allowing an insect to survive complete dehydration and extreme temperatures.
Cryptobiosis describes the state of an organism whose body water is completely dehydrated and metabolic activity has become undetectable. Our study aimed to elucidate the physiological mechanism of cryptobiosis in the highest cryptobiotic invertebrate, Polypedilum vanderplanki. Larvae of this insect rapidly accumulated a large amount of the carbohydrate, trehalose, (18% of dry body mass) during...
متن کاملGene expression changes governing extreme dehydration tolerance in an Antarctic insect.
Among terrestrial organisms, arthropods are especially susceptible to dehydration, given their small body size and high surface area to volume ratio. This challenge is particularly acute for polar arthropods that face near-constant desiccating conditions, as water is frozen and thus unavailable for much of the year. The molecular mechanisms that govern extreme dehydration tolerance in insects r...
متن کاملExtreme temperatures and violence
In his book Civilization and Climate, Ellsworth Huntington (1876–1947) noted1 that “Almost any American or European who has travelled or resided within the tropics will confess that he has occasionally flown into a passion, and perhaps used physical violence, under circumstances which at home would merely have made him vexed.” This begs the question — why is there no violent conflict when sever...
متن کاملHall Sensors for Extreme Temperatures
We report on the preparation of the first complete extreme temperature Hall sensor. This means that the extreme-temperature magnetic sensitive semiconductor structure is built-in an extreme-temperature package especially designed for that purpose. The working temperature range of the sensor extends from -270 °C to +300 °C. The extreme-temperature Hall-sensor active element is a heavily n-doped ...
متن کاملSponge-Microbe Associations Survive High Nutrients and Temperatures
Coral reefs are under considerable pressure from global stressors such as elevated sea surface temperature and ocean acidification, as well as local factors including eutrophication and poor water quality. Marine sponges are diverse, abundant and ecologically important components of coral reefs in both coastal and offshore environments. Due to their exceptionally high filtration rates, sponges ...
