--- Use of spatial, temporal and trophic niches and some aspects of thermal ecology and morphology between two species of Tropiduridae: Microlophus occipitalis and Stenocercus puyango in the transition zone of the pacific tropical and dry forest in Cerros de Amotape National Park (PNCA), Tumbes, Peru was studied. Microlophus occipitalis and S. puyango displayed an unimodal activity pattern with peak activity at 13:00, and an average body temperature for M. occipitalis and S. puyango of 34,83 and 32,17 ºC respectively. Significant relationships between body and air and soil temperatures were recorded. Most microhabitats used were the fallen logs for M. occipitalis and leaf litter for S. puyango. The diet of both tropidurids was composed of arthropods, mainly ants and insect larvae. Moreover, morphological differences in average sizes and weights were recorded between both species. The similarities found in both time of activity (temporal niche) and diet (food niche) are probably associated with their phylogenetic relationship and to own environmental features within the PNCA. Differences in the use of space and body temperature between both species would be associated with differences in the selection of microhabitats within the PNCA. Key words: Resource partitioning, Stenocercus puyango, Microlophus occipitalis, temporal, spatial and trophic niches, Cerros de Amotape National Park.
