  abstract = {{T}he factors responsible for the patterns of niche differentiation and narrow endemism have rarely been investigated in annual {M}editerranean plants. {T}his topic was addressed here by performing comparative studies on realized niches, regional occupancy, global biogeographical distribution and seed traits of a set of {A}renaria ({C}aryophyllaceae) species inhabiting southern {P}rovence ({SE} {F}rance), focusing in particular on {A}renaria provincialis, a narrow endemic restricted to the hills and modest calcareous mountains around the city of {M}arseille. {F}ield studies were carried out from 2008 to 2009 at 624 sites in the limestone mountains where {A}renaria species are likely to occur. {T}he {A}renaria species occurring in southern {P}rovence vary greatly in their patterns of regional occupancy and their biogeographical distribution. {M}ultivariate analysis of the realized niche showed that they have some similar limiting environmental factors in common, but they do not all occupy the same habitats. {S}tudies on the fruits and seeds showed that the endemic {A}. provincialis has a larger seed than its congeners and a capsule that remains closed and falls from the plant at maturity. {T}his well-differentiated diaspore specific to {A}. provincialis may be responsible for the limited dispersal capacity of this species. {P}hylogenetic analyses showed that {A}. provincialis is not closely related to the other taxa inhabiting southern {P}rovence, but rather to {A}renaria occurring in highland areas in the south of {F}rance. {T}he restricted pattern of distribution of {A}. provincialis is probably due to the past isolation event from which it originated and to its limited dispersal capacity, rather than resulting from its ecological niche range.},
