Multispecies coexistence of branchiopods (Anostraca, Notostraca & Spinicaudata) in temporary ponds of Chaouia plain (western Morocco): sympatry or syntopy between usually allopatric species

摘要: The study of the structure communities Crustacean branchiopods Anostraca, Notostraca and Spinicaudata temporary ponds in Morocco revealed existence a geographical area with particularly diversified number species. Over few hectares, 11 species, among 18 known Morocco, are present. While most them usually allopatric belong to distinct associations, indicative particular ecological climatic conditions, they can coexist Chaouia plain, either adjoining (sympatric species) or same pond (syntopic species). In one we could find up 10 phyllopods: 6 2 Spinicaudata.
