Abstract

This article focuses on the community structure and ecological niche differentiation of intertidal decapod crustaceans, specifically brachyuran and anomuran (porcellanid) crabs, on rocky shores in the Antofagasta region of northern Chile. Using null models of species co-occurrence and niche sharing, the study found that species associations are generally structured rather than random, and that the species do not share ecological niches, indicating an absence of interspecific competition. These patterns are likely influenced by microhabitat differentiation within the heterogeneous rocky shore environment, with differences observed between protected and human-impacted sites. The findings contribute to understanding species coexistence and community dynamics in highly productive upwelling zones influenced by the Humboldt Current.
