Resumen

Microlophus occipitalis is a diurnal lizard distributed on the coasts of Ecuador and Peru, of which it is tried to determine the use and resources selection of habitat, as well as the main components of its diet. Survey was done in Napique lagoon (Piura, Peru), using the Design Type I of Manly (availability and use are estimated for all individuals of the species within the study area), and the Manly Selection Ratio to determine resources selection. The composition of the diet and amplitude of the trophic niche was analyzed with the standardized Levins index. A total of 1055 observations allowed determining that M. occipitalis selected the Trunk and Stone resources. The dominant activity was Food, followed by Sunbathe. There was a high consumption of Hymenoptera, followed by the Coleoptera. Microlophus occipitalis is a species that mainly uses the trunks and stones that occur in its habitat to be able to thermoregulate. Its main activity is food. It is a carnivorous species that in the spring-summer season consumes mainly ants and coleoptera but complements its diet with flowers and leaves in low quantity, in a seemingly accidental consumption.
