Bdelloid rotifers survive desiccation and starvation by halting activity and entering a kind of dormancy. To understand the mechanisms of survival in the absence of food source, we studied the anatomical and ultrastructural changes occurring in a bdelloid species, Macrotrachela quadricornifera Milne 1886, after starvation for different periods. The starved rotifers present a progressive reduction...
Bdelloid rotifers are aquatic microinvertebrates able to cope with the loss of environmental water by entering dormancy, and are thus capable of living in temporary habitats. When water is evaporating, bdelloids contract into “tuns”, silence metabolism and lose water from the body, a condition known as anhydrobiosis. Under controlled conditions, a bdelloid species (Macrotrachela quadricornifera) was...
