Descripción
Lizards that live in the harsh climate of the Argentinean Patagonia (40°-53°S) are active for a period restricted to spring and summer when lizards perform vitellogenesis, pregnancy and birth. Herein, we present data on the female reproductive cycle, body size at sexual maturity, litter size and fat-body cycle of one of the world´s southernmost reptiles, Liolaemus sarmientoi. We also provide preliminary data on the reproductive cycle of a sympatric species, L. magellanicus. Females of both species start vitellogenesis at late spring, probably arrest or continues at very low rates during brumation, and resume it in the spring of the next year. Pregnancy starts in spring and births of L. sarmientoi (2 to 7 offspring) and L. magellanicus (3 to 4 offspring) occur over a month in midsummer. Females that give birth earlier can start a new vitellogenic cycle before autumn and perform an annual reproductive cycle. However, females which give birth later in midsummer delay the start of a new vitellogenic cycle until the next spring, performing a biennial reproductive cycle. Therefore females show the potential to adjust their frequency of reproduction according to the energetic restrictions imposed by harsh and fast-changing weather mediated primarily by strong cold winds present in the Southernmost lands of South America.
