Rotifers are very few organisms with abundant cold water. It is already known that it fights cold (even in stagnant water), boiling, desiccation, and play, and the group has been abstinent for millions of years. The humble but surprisingly strong Bertello rotifer has now surprised researchers – a recent research found a 24,000-year-old Siberian water shell and found a shot (or revived) there. Surviving 24,000 years in the cold is a new history of these species.
Rotifers are not the only living things that come from ice or ice. The same researchers found that they were about 40,000 years old possible worms in an ice-free area in the region. Old moss, seeds, viruses, and bacteria have all shown longevity on ice, resulting in proper complaint about whether pathogens can be released if Ice and glaciers melt.
Since bdelloids are often dangerous for bacteria, algae, and detritus, however, there is no need to worry about this. But as divers under the diet, newly released rotifers suggest that perhaps we should consider how species that have not been seen for centuries can return to modern technology.
Soil Cryology Lab in Pushchino, Russia, has been digging for snow in Siberia for nearly a decade. The group compares the age at which living organisms are exposed to radiocarbon which describes the surrounding soil (evidence has shown that there is no direct movement across permafrost layers). For example, last year, researchers said “the zoo is dry”Of the 35 practical experts (with an ear that is not an animal, plant, or mushroom) are counted from hundreds to decades.
In their recent discovery, cryology researchers have discovered living bdelloids that have formed fragments of soil in about a month. Among the rotifer clusters, bdelloids have a greater potential for producing parthenogenetically – for example, by producing stones – so early experiments had already begun to do so. Although the clones made the old ancestor more difficult, this greatly helped to re-examine the nature and form of the unconventional complexity.
In all of the above-mentioned studies, there are concerns about modern design. Apart from using these techniques, the team also addressed the issue by looking at the DNA present in soil samples, to ensure that contamination is not likely to occur. Phylogenetic analysis also showed that the species did not resemble modern rotifers, although there are very similar species found in Belgium.
The team had a natural interest in understanding the cold and how long the rotifers survived. As a first step, the researchers simulated rotifers mixed at -15 ° C for one week and filmed the rotifers.
The researchers found that not all rocks survived. Surprisingly, clones were often less tolerant of cold than modern rotifers from Iceland, Alaska, Europe, North America, even in the tropical regions of Asia and Africa. They were slightly more tolerant of cold than their closest relatives, but the difference was moderate.
The researchers found that rotifers could survive slowly (about 45 minutes). This is remarkable because it has gradually been formed into tiny particles that form within the cells of an animal — a development that is often life-threatening. On the contrary, preventive measures are in great demand by anyone who engages in the real estate business, which makes these recent acquisitions attractive.
While the authors are not in the business, they are developing additional tools to understand cryptobiosis — a state that regulates metabolism that allows rotifers to survive. Commenting on research related to the dissolution of large organisms, the authors say that this is particularly difficult as the body in question becomes more complex. That said, rotifers are among the most difficult to extinguish to date – packed with organs such as the brain and intestines.
