Longitudinal distribution of macroinvertebrate in a very wet North African Basin: Oued Melloulou (Morocco)
The Melloulou River presented 161 invertebrate taxa, most new for northeast Morocco. Multivariate analyses showed an invertebrate distribution governed by altitude, slope and current velocity in a highly flow dynamic. Three assemblages and a great number of ubiquitous taxa were also found. These findings are of crucial concern for managing actions.
