They are specialists of lentic environments that incorporate a dry phase, although in some cases they do occur in fishless semi-permanent waterbodies (Ferreira et al., 2011 ). Some of the water birds that are commonly found in Chott Merouane are shown in Appendix 1 in electronic supplementary material. The highly saline water also promotes the production of large branchiopods such as Branchinella spinosa Milne Edwards, Branchinectella media Daday, and the brine shrimp Artemia salina L.
