Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | Eggs | Fecundity | Larvae
Laying of third egg which is variably smaller than the first two eggs in the same clutch is correlated to the facilitation of brood reduction (when beneficial) and sex-biased investment decisions, i.e., hormonally-mediated female reproductive recrudescence (Ref. 95045).
