New and interesting data on distribution and ecology of mayflies from Eastern Morocco (Ephemeroptera)

The moulouya's watershed and the oriental morocco have been always considered as the poorest in terms of ephemeroperological settlement. thanks to our repetitive campaigns,and the difficult territories carried out for the first time,including the high plateaus,the oriental sahara and the oriental parts of the rif,middle atlas and the high atlas,we have been able to identify at least 23 species of the entire study area representing almost half of the moroccan ephemeral fauna. this work is dedicated to the monitoring of mayflies populations and update the few data available on this group,mentions new records and attempts to clarify the distribution of this order by giving an overview of the ecology of every single found species. © 2017,of mohammed 1er oujda morocco.
