RAMIREZ-PERILLA, JAIME. Ex situ Annual Egg-Laying Cycles of Rhinoclemmys melanosterna, R. diademata and their Hybrids(Reptilia: Testudines: Emydidae: Batagurinae). Acta biol.Colomb. [online]. 2005, vol.10, n.2, pp.113-121. ISSN 0120-548X.

R. melanosterna, R. diademata and their hybrids (R. melanosterna x R. diademata) present annual continuous egglaying cycles with maximum frequency during the rainy season. The period of maximal annual egglaying for hybrid R. melanosterna x R. diademata is earlier than its parents. Aparently there is not direct relation between the ad libitum food offer and Rhinoclemmys sp egglaying cycles.
