Ants were sampled in the nest of Pogonomyrmex rugosus in the state of Durango, M & eacute;xico, in 2023, in four ecosystems: North American Deserts (DAN), Semiarid Southern Elevations (ESM), Warm-Dry Forests (SCS) and Temperate Sierras (ST). The most abundant species in these ecosystems was Pogonomyrmex rugosus. To determine the morphometry in each ecosystem and its relationship with environmental factors, 15 measurements were made (in mm) of the ant's body: head (4), mesosoma (4), legs (3), gaster (2), eyes (1), and antenna scape (1). In addition, the temperature, precipitation, radiation, elevation, and soil pH were obtained in each of the sites sampled. A one-way analysis of variance (ANOVA) was carried out on each measurement, and a correlation between the morphometric and environmental variables was obtained. It was observed that the head and gaster are larger in ESM and smaller in ST, while the eyes are larger in SCS and smaller in DAN. In addition, correlations were found between temperature with middle legs and scape, and elevation with mesosoma length.
