Descripción
In the cold temperate climate of Patagonia, reproduction and growth of ectotherms are restricted to brief seasons, particularly at high latitudes. This energy constraint has affected the evolution of life history traits such as sexual maturity, clutch size, offspring size, reproductive effort, and fecundity. Limitations on the timing of reproductive events and the allocation of energy to offspring have a vital role in the fi tness of the species, and it is expected that oviparous and viviparous lizards respond with inter- and intra-speci fi c differences to different environmental conditions partly because of thermal constraints on the  development  of nestlings.  We studied the  reproductive  cycles  of  two populations in  Patagonia, Argentina (43º  and 46ºS), of each of three species: the southernmost oviparous liolaemids, Liolaemusbibronii,  and  Liolaemus  boulengeri,  and  the  viviparous  Liolaemus  lineomaculatus.  The  three  species showed annual and synchronous reproductive cycles between males and females with birth or hatching occurring at the end of summer, showing common evolutionary paths in their reproductive biology. In addition, the oviparous species seem to have adapted to cold and arid environments at high latitudes, in contrast to a major prediction of the cold climate hypothesis for the evolution of viviparity.
