Resumen:
In this chapter we provide a detailed and integrated review of the reproductive biology and life-history traits related to reproduction of lizards that inhabit the cold and harsh environments of Patagonia, Argentina. Lizards from the genus Liolaemus, Phymaturus, and Homonota have shown distinctive life-history traits, such as the retention of eggs in the oviducts during most of embryogenesis, evolutionary transitions from oviparity to viviparity, adaptive synchronization of parturition with benign environmental conditions, signs of parental care, plasticity in the timing of reproductive events, prolonged-multiennial reproductive cycles in females, interspecific variability in male reproductive cycles, and physiological mechanisms in males to synchronize with female cycles, among others. We discuss the adaptation of reproductive cycles to the energetic constraints imposed by environmental conditions of Patagonia. We focus on understanding how reproductive physiology could be affected by environmental stressors with the aim of contributing to successful conservation strategies.
