Abstract
The hyperarid Atacama Desert, without vegetation, extends for 740 km N to S in Chile. The presence of vertebrates with low mobility in this environment indicates the development of special adaptive capacities and the presence of little-explored ecosystem interrelations. We studied the distribution and density of reptiles and mammals in two altitude gradients of 76 km each. On the other hand, we use a stable isotopes analysis for characterization of the trophic niche in reptiles. We found that the reptiles and mammals are infrequent and have low densities. The silverfish of the Zygentoma order are key prey in this community. Reptiles overlap in the consumption of trophic sources, but differ in their positions in the trophic web. The information is complemented with information about predation among reptiles in this extreme ecosystem.

期刊介绍：
GAYANA is a scientific journal published by Universidad de Concepción, Chile. It is the modern version of Gayana Oceanología and Gayana Zoología. Therefore its numeration starts at volume 63(1).
GAYANA covers all aspects of zoology and oceanographic research. It is structured in five sections, defined by subject or discipline: Ecology, Biodiversity and Taxonomy, Earth Sciences, Evolutionary, and Applied Biology and Environmental Biology. Each section is in charge of an editor who receives and manages the manuscripts sent for evaluation in close collaboration with the editorial board.
