Structural and ecological variation of the pontic phytogeographical element from the coastal Karst to the Southwestern Alps
This paper discusses the geographic trends in the distribution of the Pontic phytogeographical element (including Pontic-Mediterranean species) from the northern Adriatic coasts (Trieste Karst region) to the South-East Alps and pre-Alps. The number of Pontic species decreases slightly from the Karst towards the pre-Alps, with a sensible reduction from the pre-Alps towards the centre of the Alpine chain. This pattern can be related to temperature. The geographic variation of life forms shows a simplification of the life form spectrum: the geophytes, being less dependent on environmental conditions, are the life form with the lowest geographic variation.
