Aquatic insect communities in inland waters of Chile are characterised by the presence certain species depending on water quality, but there is little information statistical ecology structure communities. The aim present study was to apply null models explain aquatic insects middle zone Loa River, Atacama Desert (Antofagasta Region, Chile; 23°S). results co-occurrence showed that associations random, while niche sharing share ecological niches and consequently interspecific competition. reported taxa similar for other North Patagonian rivers terms community structure.
