  1. Mean values (± standard error) of hydrated (H) and desiccated (D) lines of A. ricciae and M. quadricornifera at start of the experiment (M0) and after four (M4), eight (M8) and twelve (M12) months (= months of continuous hydration for H or subsequent desiccations for D). Fecundity, reproductive days, reproductive effort (= number of eggs per reproductive day), eggs produced till 10-d-old, age at the first reproduction, and longevity are reported.
