DONNEES PRELIMINAIRES SUR LE MENU TROPHIQUE DE TROIS ESPECES DE TOURTERELLES DANS LES PALMERAIES DE OUARGLA (SAHARA SEPTENTRIONAL-EST D’ALGERIE)

Abstract

In recent decades, the genus Streptopelia (S. decaocto, S. senegalensis, and S. turtur) has become increasingly present in the various phoenicicultural environments of the northern Sahara-East of Algeria, particularly in Ouargla basin.
