These anthropic pressures combined with drought episodes, typical of semiarid Morocco gathers a high biodiversity because of regions such as the study area, results in an its great landscape and climate heterogeneity important loss of aquatic habitats (Mabrouki et (Dakki 1997). Unfortunately, this biodiversity al. 2016b; Taybi et al. 2016b, 2017). is threatened, particularly that inhabiting aquatic Within aquatic ecosystems, macroinvertebrates, ecosystems.
