“…1). This species is a medium-sized lizard endemic to northwestern arid Patagonia (Perez et al, 2011). At present, P. tenebrosus is only known from a very restricted area in southwest Río Negro and Neuquén, Argentina (Kubisch et al, 2017).…”

Global warming can significantly affect many aspects of the biology of animal species, including their thermal physiology and physiological performance. Thermal performance curves provide a heuristic model to evaluate the impacts of temperature on the ecophysiology of ectotherms. When integrated with other thermal biology parameters, they can be used to predict the impacts of climate change on individual fitness and population viability. In this study, we combine holistic measures of thermal physiology and the thermal sensitivity of locomotor performance with environmental temperatures measured at fine scale to estimate the vulnerability to global warming of the endangered Patagonian lizard Phymaturus tenebrosus. Our results indicate that this lizard exhibits its preferred temperatures and maximum locomotor performance at higher temperatures than the mean temperature it currently experiences in its habitat. In addition, it exhibits a low effectiveness of thermoregulation, being a poor thermoregulator. In view of the results obtained, we suggest that the climatic conditions of Patagonia may be advantageous for P. tenebrosus to survive future global warming, since its thermal physiology and locomotor performance may improve under increasing in environmental temperatures in its habitat.

“…In northern Patagonia within the Provinces of Rio Negro and Neuquen, Argentina there are 103 species of lizards, including five families and 10 genera (Avila et al, 2013; Pérez et al, 2011), plus the Patagonia tortoise ( Chelonoidis chilensis ) (Bonin et al, 2006). To the south in central Patagonia in the Province of Chubut, 38 species of lizards occur primarily in steppe habitat (Minoli et al, 2015).…”

Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?

Addressed here is the biogeographical-vexing question of why the guanaco (Lama guanicoe) is the only large mammal on the big island of Tierra del Fuego, answered by comparing alternative colonisation hypotheses. A multidisciplinary examination was conducted into the archaeological, ecological, evolutionary, geographical, genomic, glacial and zoological past, plus distribution of native terrestrial vertebrates in the Patagonia of southern South America. Notable disparities exist between main Patagonia (2.5 species/10,000 km 2 ) compared with Tierra del Fuego (1.8). In the similar-sized area of mainland Patagonia just north of the Strait of Magellan there are 12 reptiles, 7 amphibians and 34 mammals = 53 total species; Tierra del Fuego has 13. Despite being the size of Switzerland and only 3.5 km from the mainland, Tierra del Fuego has no species of snakes, salamanders, frogs or turtles, only one lizard, one toad, nine small mammals, one carnivore and one ungulate, the Guanaco.

“…This taxon has been recently redescribed (Nori et al 2010a) and the current known populations are restricted to the north of Río Negro province (Nori et al 2010b, Pérez et al 2011) approximately 430 km in a straight line from Península Valdés. The populations cited as Liolaemus goetschi in Scolaro (1976b) are considered as Liolaemus melanops since subsequent works showed molecular (Avila et al 2006b) and morphological (Abdala 2007, Abdala et al 2012b) differences between these two taxa.…”

An accurate estimation of species and population geographic ranges is essential for species-focused studies and conservation and management plans. Knowledge of the geographic distributions of reptiles from Patagonian Argentina is in general limited and dispersed over manuscripts from a wide variety of topics. We completed an extensive review of reptile species of central Patagonia (Argentina) based on information from a wide variety of sources. We compiled and checked geographic distribution records from published literature and museum records, including extensive new data from the LJAMM-CNP (CENPAT-CONICET) herpetological collection. Our results show that there are 52 taxa recorded for this region and the highest species richness was seen in the families Liolaemidae and Dipsadidae with 31 and 10 species, respectively. The Patagónica was the phytogeographic province most diverse in species and Phymaturus was the genus of conservation concern most strongly associated with it. We present a detailed species list with geographical information, richness species, diversity analyses with comparisons across phytogeographical provinces, conservation status, taxonomic comments and distribution maps for all of these taxa.
