Life Cycle:

Life Cycle:

In A. rhodense, the three sexual morphs are produced by selfing hermaphrodites and crossing females, independently of the environmental conditions (Chaudhuri et al., 2015).  However, in A. freiburgense, mothers exposed to crowding cues derived from high population densities produce mostly hermaphrodite offspring. In the absence of those crowding cues, mothers produce predominantly females and a few males (Tandonnet et al., 2020, Zuco et al., 2018).
