  abstract = {{T}he 'central-peripheral' hypothesis has provided a baseline for many studies of population dynamics and genetic variability at species distribution limits. {A}lthough peripheral populations are often assumed to occur in ecologically marginal conditions, little is known about whether they effectively occur in a distinct ecological niche. {A} cross-taxa analysis of 11 {M}editerranean vascular plants were studied. {W}e quantified variation in the ecological niche between populations at the northern range limits of species in {M}editerranean {F}rance and those in the central part of the distribution in continental {S}pain or {I}taly in 2013-2014. {W}e analyzed both the macro-ecological niche where populations occur in terms of broad habitat and altitudinal range and the micro-ecological niche where individual plants grow in terms of soil and structural biotic and abiotic characteristics. {M}ost species occur in a single broad habitat type common to central and peripheral populations and have a narrower altitudinal range in the latter. {I}n contrast, for the micro-ecological niche we detected marked variation in several niche parameters among central and peripheral populations. {A}lthough many differences are species-specific some are common to several species. {W}e found a trend towards narrower micro-niche breadth in peripheral populations. {O}ur results illustrate the importance of studying the precise ecological characteristics where plants grow and the pertinence of a multi-species approach to correctly assess niche variation. {T}he ecological originality of peripheral populations underlines their evolutionary potential and conservation significance.},
