Biogéographie des apidae (hymenoptera; apoidea) d’algérie et monographie des espèces d’eucerini et anthophorini dans la région des aurès.

Abstract

Anthophorini and Eucerini, like the whole of Apoidea, occupy a key position in the ecosystems. They take part in a dominating way in pollination of the entomophilous plants. They are particulary remarkable by their very targeted floral choices. Indeed, the majority of the species belonging to these tribes is polylectic even oligolectic. Unfortunaly, these tribes are very badly known. For an unspecified study applied, it was thus necessary to arry out a signifiant synthesis on the taxonomy and the biogeography of this group. From the many data resulting from the laboratory of Biosystematics and Ecology of Arthropods and and personal collections, several mechanisms are built. First, a monograph of the species at regional level (Aures) is achieved. On the other hand, catalog is taken over the commonly recognized synonyms of different taxa. Turthermore, we studied the functional features on phenology of each species studied. At the end of this work, we collected 1525 specimens belonging to 68 species, 5 genus and 17 sub-genus of Anthophorini and Eucerini were listed on a regional level, Eight species are new for our fauna. Thus Eucerini includes 62.36% of species diversity compared to anthophorini which represent only 37.64%. To understand their dynamic, distribution maps are realized. In the same way, their diversity centers were highlighted on several geographical and taxonomic levels. The world distribution of Apidae and richness of each biogeographic area (Ethiopian, East-Paleartic and West-Paleartic) are specified.
