Abies nebrodensis (Lojae.) Mattei, a relevant example of a relie and highly endangered species

Vendramin, G. G., Michelozzi, M., Tognetti, R. & Vicario, F. : Abies nebrodensis (Lojac.) Mattei, a re levant ex ampie of a relic and highly endangered species. - Bocconea 7: 383-388. 1997. - ISSN 11 20-4060. Allozyme, DNA markers, sequence data and monoterpenes have been used to clarify the genetic and taxonomic relation ships between diffe rent populations of Abies alba Mill. and the only existing population of Abies nebrodensis (Lojac.) Mattei , a relict lir restricted to a s in g le locality in Sicily. A high level of differentiation was found usin g ali th e different approaches. The genetic distance between A. nebrodensis and the group of A. alba populations was found to be much greater than that among A. alba population s located more than 1000 km apar!. The results provide support for th e considering A. nebrodensis and A. alba as di stinct taxonomic entities.
