Distribution of nematode orders in a river subjected to pollution: the Monachil river (Granada, Spain)

Abstract

The water quality of an aquatic environment can be suitably assessed, from a nematological point of view, by examining the presence of higher taxonomic categories (families, suprafamilies or even subclasses). Order was chosen in the present study to examine water quality variations occurring along the course of the Monachil River (Granada, Spain). Rhabditida were detected in those stretches of the river exposed to pollution, while Monhysterida, Arueolaimidu and Enoplida were detected in unpolluted areas.
