The Maritime Alps are one of the 'hot spots' in the Mediterranean basin. This study investigated two endemic plants, Moehringia lebrunii and Moehringia sedoides (Caryophyllaceae) in order to increase knowledge of the vegetation of this region, and to investigate possible conservation strategies. Ecogeographic surveys and molecular analyses were...

Saxifraga callosa is a species spread in South-Eastern France and Italy with high diffusion in Maritime Alps. This species lives in more or less vertical limestone rocks at an altitude of between 200 and 2,000 m and it ranges from Southewestern Alps (Cottian and MaritimeAlps, Provence) through the Apuane Alps and the Apennines to...

Brassica rupestris Raf. is a chasmophyte species that includes two subspecies both endemic to Central-Western Sicily (Italy). ISSR were used to detect the genetic diversity within and among eight populations representative of the species' distribution range. High levels of genetic diversity were revealed both at population (PPB = 53.88%, HS =...

Primi risultati sulla fologeografia di due specie endemiche silicicole delle Alpi Marittime

Sono qui presentati alcuni studi sulla biodiversità delle Alpi Marittime: studi ecologici e studi sistematici.

Previous studies have indicated that several plant species had shown remarkable resistance to Pleistocene climate changes and survived the Last Glacial Maximum in scattered ice-free refugia within the European Alps and peripheral areas nearby. The 'Expansion–Contraction' model has been proposed to describe the responses of organisms to...

Primula allionii is endemic to a tiny area of the Maritime Alps and has one of the narrowest distribution ranges in this hotspot of biodiversity. Phylogeographical patterns in P. allionii were studied using plastid DNA markers and dominantly inherited markers (AFLP and ISSR) to verify any admixture between P. allionii and the sympatric P....
