ResumenClutch size and egg ma.c are not related in a mountain pop’tion of Lacerta schreiberi. This endemic Iberian lacertid lays only one clutch (7—24 eggs) per year. Synchronicity among breeding femalec is related to a long incubation period, which leaves a short activity period for juveniles before their first wintering. The length of the incubation period shows a strong relationship with environmental tempera­ ture. Vitellogenesis starts at the beginning of the activity season, and clutch size is related to female SVL. Clutch size corrected for maternal SVL is not correlated with egg mass and shows no variation among years. However, egg size and hatchling SVL show among-year and interindividual variation and are not related to female SVL or relative clutch mass. Egg mass is positively correlated only with the laying date. We suggest that clutch size depends only on stored lipids remaining after wintering and environmental factors could be responsible for egg size variation dur­ ing vitellogenesis.
