The spatial distribution of animals in a landscape depends mainly on the distribution of
resources. Resource availability is often facilitated by other species and can positively …

How ectotherms exploit thermal resources has important implications for their habitat
utilization and thermal vulnerability to climate warming. To address this issue, we …

An increase in temperatures and frequency of drought events are predicted in the High
Andes due to climate change. Species could respond with changes in its range, abundance …

Sister species that live in sympatry provide the possibility to analyse the level of divergence
in their ecological, physiological and life-history traits and how they can coexist without out …

Background Life diversifies via adaptive radiation when natural selection drives the
evolution of ecologically distinct species mediated by their access to novel niche space, or …

The diversity of habitats generated by the Andes uplift resulted a mosaic of heterogeneous
environments in South America for species to evolve a variety of ecological and …

Global warming can significantly affect many aspects of the biology of animal species,
including their thermal physiology and physiological performance. Thermal performance …

In the highlands of the Andes, lizards must balance precisely the allocation of energy for
growth and reproduction to ensure their survival. We studied the individuals' age, growth …

Body temperature is the most important ecophysiological variable affecting reptiles' life
history. Moreover, thermoregulation in ectotherms implies a struggle to reach preferred …

Small lizards can accommodate to constraints imposed by temporal changes in ambient
temperature through a combination of adaptive evolution and behavioral and physiological …
