We analyzed the effects of population density and climatic variables on the rate of population growth in the guanaco ( ), a wild camelid species in Lama guanicoe South America. We used a time series of 36 years (1977-2012) of population sampling in Tierra del Fuego, Chile. Individuals were grouped in three age-classes: newborns, juveniles, and adults; for each year a population transition matri...
