Substantial differences in both life-table characteristics and reproductive patterns distinguish bdelloid from monogonont rotifers. Bdelloids reproduce only asexually, whereas most monogononts are cyclical parthenogens. We explore some of the adaptive consequences of these life-history differences using a computer model to simulate the evolutionary acquisition of new beneficial mutations. A one-locus...
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...
