Abstract Spatio-temporal scales have a clear influence on microbial community distribution and diversity are thus essential to consider identify study the dynamics of microorganisms. The invasive tick species Hyalomma marginatum has recently become established in southern France. It carries pathogens medical veterinary interest including Crimean-Congo hemorrhagic fever virus, Rickettsia aeschlimannii, Theileria equi Anaplasma phagocytophilum among others. While pathogenic communities H. were identified their spatial characterised, temporal still unknown.
