These diagrams show the existence of the three basic annual heat cycles, the basis for classification into dimictic, monomictic, and amictic lakes.
Sexuality is initiated by an environmental stimulus that induces amictic (female-producing) females to produce mictic (male-producing) daughters.
Well-fed, amictic females produce typical, thin-shelled amictic eggs that are subitaneous and develop without arrest into females.
In the present study, we experimentally test several hypotheses regarding the nature of the food-limitation stimulus that induces diapausing amictic eggs in S.
Under these conditions, the food concentration remains high, and amictic females produce only subitaneous eggs.

Cyclic parthenogenetic Daphnia reproduce by amictic parthenogenesis as long as the environment remains favorable.
Only amictic females (asexually reproducing) were included in the experiments; mictic females (females producing males or sexually produced resting eggs) were discarded.
If this is true, then the data would lend support to the notion that truly asexual taxa possess general-purpose genotypes even in a limited comparative situation (i.e., compared with close relatives that have both mictic and amictic phases in their life cycle).
Any females later proving to be mictic instead of amictic females were discarded.
Snell (1986) found that the number of offspring produced by amictic, but not mictic, females of this species increased continuously between 18 [degrees] and 38 [degrees] C.
