“…thaul were captured during September 2012 on two small ponds at Carrera Pinto (27º06′40.2′′ S, 69º53′44.3′′ W; 2,000 m.a.s.l. ), a small oasis in the Atacama Desert that is known to be the northernmost population of the species (Correa, Sallaberry, Gonzalez, Soto, & Mendez, ). In both ponds, we performed an exhaustive search across microhabitats (below rocks, in the vegetation and in the water).…”

For ectothermic species with broad geographical distributions, latitudinal/altitudinal variation in environmental temperatures (averages and extremes) is expected to shape the evolution of physiological tolerances and the acclimation capacity (i.e., degree of phenotypic plasticity) of natural populations. This can create geographical gradients of selection in which environments with greater thermal variability (e.g., seasonality) tend to favor individuals that maximize performance across a broader range of temperatures compared to more stable environments. Although thermal acclimation capacity plays a fundamental role in this context, it is unknown whether natural selection targets this trait in natural populations. Additionally, understanding whether and how selection acts on thermal physiological plasticity is also highly relevant to climate change and biological conservation. Here, we addressed such an important gap in our knowledge in the northernmost population of the four‐eyed frog, Pleurodema thaul. We measured plastic responses of critical thermal limits for activity, behavioral thermal preference, and thermal sensitivity of metabolism to acclimation at 10 and 20°C. We monitored survival during three separate recapture efforts and used mark‐recapture integrated into an information‐theoretic approach to evaluate the relationship between survivals as a function of the plasticity of thermal traits. Overall, we found no evidence that thermal acclimation in this population is being targeted by directional selection, although there might be signals of selection on individual traits. According to the most supported models, survival increased in individuals with higher tolerance to cold when cold‐acclimated, probably because daily low extremes are frequent during the cooler periods of the year. Furthermore, survival increased with body size. However, in both cases, the directional selection estimates were nonsignificant, and the constraints of our experimental design prevented us from evaluating more complex models (i.e., nonlinear selection).

“…However, the geographical distribution of many species recently has been clarified, improving information on taxa known only from type localities (Formas, 1995) and the fauna of undersampled areas (Mendez et al 2005 ), as well as information from Chilean herpetological collections (e.g., Nuñez, 1992;e.g., Sepúlveda et al, 2006;Correa et al, 2007).…”

“…En Chile, es uno de los anfi bios más abundantes (Díaz-Páez & Ortiz 2001) debido a que ha logrado adaptarse a distintos tipos de hábitats, presentando una amplia distribución latitudinal, delimitada entre Carrera Pinto, Región de Atacama (27º 06' S, 69º 53'O) en el norte (Correa et al 2007), hasta Aysén (45º 30'S, 70° 20'O) en el sur (Cei 1962;Duellman & Veloso 1977;Victoriano et al 1995;Díaz-Páez & Ortiz 2001;Iturra-Cid 2010), y desde la costa hasta 3.125 m sobre el nivel del mar (Correa et al 2010). Esta especie es capaz de vivir en ambientes térmicos tanto de bajas temperaturas como de altas temperaturas (Sommaruga 2001).…”
