Diversity and Ant Community Composition in Some Algerian Islands

Abstract The present paper seeks to study the diversity and ant community composition of some Algerian islands. This is considered as first exhaustive survey species islands since 1957. was carried out in spring summer seasons between April July two years 2014 2015. Vegetation richness, island area, mainland distance, elevation variables were measured for each island. Relative abundance (RA), frequency occurrence (FO), well richness (S), Shannon’s index (H), equitability (E) used compare pattern among Patterns structure compared sampling through ordination analysis (nonmetric multidimensional scaling [NMDS]). SIMPER using a Bray–Curtis similarity matrix performed determine contribution dissimilarities Canonical correspondence (CCA) highlight impact environmental on community. All analyses computed by PAST software. Two methods (pitfall trap hand collecting) used, which led identification 1039 individuals belonging 16 species. Diversity indexes different Ant significantly regions Bejaia Jijel. Three contributed 50.74% differences regions. Part influenced directly or indirectly three variables: vegetation distance.
