Daniel Stec and other iEcoTeam members just published a paper in "Organisms Diversity and Evolution."


In the study, the authors examined how tardigrades, microscopic animals known for their ability to survive extreme conditions, use cryptobiosis across different environments. They focused on two types of cryptobiosis: anhydrobiosis (survival without water) and cryobiosis (survival at freezing temperatures). The study took place in a pine forest bordering a desert in Poland, where samples of moss were collected from the forest edge to its center to see how tardigrades' abilities to withstand desiccation and freezing varied across this gradient.

Tardigrades living in the center of the forest had better survival rates under both extreme conditions compared to those near the desert. Surprisingly, no correlation was found between the abilities to survive desiccation and freezing, challenging the idea that these two survival strategies are linked. The study highlights how environmental factors shape tardigrades' ability to survive extreme conditions.
