Phenotypic trait Reference
Shorter incubation times in the montane population. Iraeta et al. 2006
Larger hatchlings in the lowland population. Iraeta et al. 2006
Faster growth in lowland juveniles (reciprocal transplant experiment). Iraeta et al. 2006
Faster growth in lowland juveniles (common garden experiment). Iraeta et al. 2013
More plastic activity levels in response to food availability in the lowland population. Iraeta et al. 2008
Larger clutches of smaller eggs in the lowland population.
Iraeta et al. 2008 Iraeta et al. 2013
Longer flight distance for pregnant females in the montane population. Iraeta et al. 2010
Relatively longer hind limbs in the lowland population. Iraeta et al. 2011
Larger adult females in the montane population. Iraeta et al. 2013
Countergradient variation in body size: the genotypes that presumably control the key adaptations of the lowland population (larger eggs and hatchlings, and faster growing juveniles) occur in a low-productivity environment in which lizards grow more slowly and reach a smaller adult size.
Iraeta et al. 2006 Iraeta et al. 2013
More and relatively larger femoral pores in males from the lowland population. Iraeta et al. 2011
Greater development of the sexual coloration of the head (i.e. larger colored surface) in males from the lowland population.
Iraeta et al. 2011 Llanos-Garrido et al. 2017
Increased saturation of the sexual coloration of the head in males from the montane population. Llanos-Garrido et al. 2017
Males respond to the activation of the immune system by reducing the extent of the sexual coloration of the head in the lowland population, and its saturation in the montane population. Llanos-Garrido et al. 2017
Higher rates of infestation by tick nymphs in the montane population (no ticks in the lowland population). Llanos-Garrido et al. 2017
