Chironomid (Diptera, Chironomidae) species assemblages in northeastern Algerian hydrosystems
The aim of this paper was to analyze the distribution of chironomids (Diptera, Chironomidae), and determine their substrate preferences, from two hydrosystems located in northeastern Algeria: the Kebir-East and the Seybouse wadis.Sixty-five species were recorded in 49 sampling sites distributed along the main courses of the two hydrographic nets an
